  1. @import url(http://www.modelflying.co.uk/CuteEditor_Files/Style/SyntaxHighlighter.css); @import url(/CuteEditor_Files/public_forums.css); good morning Steve ty for your comments there i was looking on there last night trying to gain some extra knowledge on motors n esc so i opted for what i could work out.. on the prop / adpt . I just had the same comment there from Tim in his pm didnt remember about that till i had ordered .. 3mm prop adaptor and a 8x4 slow fly prop. is Tims suggestion... Thank you for the link. and yes will hold five for your testing .. will make life a little easier having the same motor and much appreciated ..   Yes I'm thinking about keeping the servos at the back but also considered putting the inside the rear of the plane with just a small push rod.. before covering maybe a little hatch. i don't like seeing the servo on air craft  just looked at your link there isnt a 8x4 only a 8x6 would that be to much ?? but have found this one 8x3.8   Adrian @import url(http://www.modelflying.co.uk/CuteEditor_Files/Style/SyntaxHighlighter.css); @import url(/CuteEditor_Files/public_forums.css); Edited By Adrian Day on 17/01/2012 11:38:57 Edited By Adrian Day on 17/01/2012 11:44:26
  2. well the last few days the build has slowed a little due to being busy. so only done the small things that i can before bed .. adding formers and wing rods so on. i should put some pictures on really so you can see the progress.. will do that soon as i can.   one thing i have been doing is thinking about the power side of things and working out the best that i can from what Tim and Steve have been teaching me .and PM'ing Tim my info just to make sure im getting this model the way he intended it.. i have now chosen the following electrical components     MOTOR ESC LiPo 2 SERVO'S Just ordered them from G.C so will be keeping eye out for the postie in the next few days Then once that gets here the build will come together pretty fast .. i think. hope this is keeing you up to date Adrian  Edited By Adrian Day on 17/01/2012 10:41:17
  3. Steve thank you Worth the try ..didnt think i got it ...need to work on my electrical skills   . there was a 10 in there some where .. didnt know how to work it out ..so its battery / motor =0.1 ........ rather than what i put being motor / battery   i guess that the run would more likely be to get my model as its would run out 4 mins earlier than i would have thought   couldn't remember ohms law so just put you equation   think maybe i should just leave it to the pro's dont think i have the brain for it Adrian            
  4. Afternoon all   well been building over the last 2 days, been very productive, now got the fuselage half built up got all internal formers in and some of the main turtle decks stringers in place with rear window bars in too, i have made the tail up with hinges so now control surfaces moving. have covered the tail plane ..   have chosen the colour scheme going for a blue and white colouring. i want to get the pix-e stickers made up with white writing but i cant do printing as printers gone pop will have to have a think   will post some more pictures soon showing the progress Adrian  
  5. As a relatively new comer to the world of model flying and construction I dont think you should change the name of RCM&E its says what it is .. the RCM speaks for its self and these days the E is covered by the electric flying model ok in the 60's it covered the rc gear and much more when electric flight was seldom used, As i have found building my model this week if it wasnt for the mag, this site and its great readers. informing me how the electronics side works.. I wouldnt have got anywhere.   PLZ DONT CHANGE ANYTHING its great as it is.

  6. Steve this is going to be a hard one for me don’t think im good enough for this test. Though your a good teacher maybe im just not a great student Are you quoting a little of ohms law if my memory serves me correctly?? p=v x i Ok here goes.. MOTOR working on the assumptions of the sports model 100w per lb as you said earlier in post. 2.5lb x 100w = 250w / (3s) 11.1 = 22.52amps so on that i would say go with this one motor with the workings looking something like this MAX CURRENT TO USE 22AMP OR 244WATTS ---- 22A x 11.1v = 244w KV YOU NEED 2200 KV x 11.1V = 24420 rpm AS HIGH RPM I WOULD SAY I WOULD USE WITH A SMALL PROP ESC   Im going with this one ESC CURRENT CAPACITY 30AMP WITH 40 AMP FOR 10 SEC BURST reason for using this 30amps is it 2amps over the 60sec burst rate of the max amp the motor can handle and can run on either 2s or 3s LiPo as you asked.. As for how long would the battery last my working out may be wrong but Im going to say 10 mins max Working out like this … motor takes a constant 22 amp draw so im working it out like this 2200mah bat = 2.2amps so 22A draw from motor / 2.2A bat =10min or 2.2 x 10min = 22A don’t know if this is right or not never worked on this before. Maybe a little backwards though JUST A GUESS.. SORRY IF this is wrong maybe I should stick with building and let others tell me what to put in.. Adrian dont think i got it though
  7. Tim / Steve Do you Think you could do the same thing a standard multi meter or would it not get the same results??   if not may be an investment that may come in handy at some stage and cost effective for the future Adrian @import url(/CuteEditor_Files/public_forums.css);
  8. Steve     Wow so much to take in in one go think i will have to read that a few times to get in the brain... firstly thank you for the acceptance of the friend request   next lets see read a little and write a little so much to take in     have made some changes now to my excel list as didn't realise I had put wrong digits now it might have the right workings thanks you again...   on the kv/watts well i didn't think there was going to be a simple exchange there just the luck i have been on a number of sites looking for motors and got only the kv with not much other information.. i was kind of wondering if there was another way that you can work things out like working backwards or something i may have missed. but that's good that there isn't something and its just not pos.   so on the motor front the idea is if you up the volts /amps in doing so changes the kv so adjust the prop size in accordance e.g: motor speed changing faster then you would put smaller prop ... if you lower the volt/amp then you would put larger.. ..would that sound about right?? and as you say about companies putting the burst amps making you think you can push it but in the most part and for safety you can only use 50% of what they are putting   i hope what i have put sounds about right but think this is going to take some getting round.. will work on that one thanks again for everything Adrian      
  9. TY Stephen for your nice comment ... tying my best .... welcome to my build and hope you'll come back Adrian@import url(http://www.modelflying.co.uk/CuteEditor_Files/Style/SyntaxHighlighter.css);@import url(/CuteEditor_Files/public_forums.css);
  10. Well today got a little more done to the pix-e. Cut the fuselage side parts and built the first side looking ok on the board and laying perfectly flat.   Fridays tasks side 2 of fuselage and cut the rest of the joining 1/8 sq parts from the plan. then fit F2 F3 and close the tail end together   lets see how the day goes shall we? slow but productive   little worried about making the landing gear as not sure by the design angles and fittings??? any one know how please let me know TY Adrian @import url(http://www.modelflying.co.uk/CuteEditor_Files/Style/SyntaxHighlighter.css);@import url(/CuteEditor_Files/public_forums.css);
  11. Tim   thank you am really trying taking my time to make sure that it looks pretty close to your workmanship.   An old mane once said to me if you find something that works for you stick to it, if only to get you by those dark evenings. i would say that as you said in your post if you know a particular setup you sick to , i think your doing it right from what i see and the models you build , i only dream to be that good, and your living that dream,   A hobby and something your great at what more could you ask for that and you have a partner who has the hobby blood to ... now thats hard to come by cant wait to see what you come up with next time   Regards Adrian  
  12. well i think the green ones taste of washing up liquid sad thing is love the green ones heem thinking about it i like all green sweets wine gums, fruit gums, american hard gums oh and the jelly babies got me wanting some now .. our local cost cutters do them 500g bags little walk me think
  13. Good Morning All day 3 of building the little pix-e went ok with just some cleaning up of joints to be done but structure is solid for its 1/8th sq parts,   today will be to start the fus may only be the cutting of parts and a little building depending on time, think its going ok ???? will say Tim, idea of constructing joints makes for stronger joining   Adrian
  14. Posted by Steve Hargreaves on 11/01/2012 16:08:09: Of course you can Adrian.....I need all the friends I can get.....   Yep, thats pretty much it on the maths.....remember its always better to err on the side of caution when sizing components.....anything working flat out will not reward you with a long life. Always allow a bit of "headroom" & frankly the difference in size/weight & cost between a 12A & an 18A ESC will be negligible so I would probably go for a 18A one....but thats just my personal feeling.   Plus if you find that your mates Pix E is faster than yours you can get more power with a bigger prop without bothering to change the ESC (assuming the motor will take it of course!!)...   So let us know which motor you get & we can decide on a prop & then run it all up on a Wattmeter & check that we have the correct power & that nothing is working beyond its limit......if we don't or it is we can change the prop.....   The Pix E is a vintage type design & will waft around on very little throttle turning a big prop so slowly you can count the blades......think lazy summer evenings & you're about there....   have sent a friend request dont know if it sent right first i have done TY Will have to invest in a wattmeter for sure got a little to get in between , pending on money if you know what i mean, some one may have to talk me round how do do the wattmeter test,   oh now thats a good idea looking forward to summer now cant wait, summer eve flying is a distant memory sad to say something i havent done in over 10 years last time was with my dear departed dad,   Adrian    
  15. well from what Steve put i have made a simple program in excel for further use hope that its a working out close to if you see anything in the picture that dont make sence please tell me, its just for a basic idea,   I have to agree with Pete B on that Steve i have to say your way of explaning things is in easy terms that most can understand so thats perfect . thank you Tim for your input on the power and what it does on the setup your using so do you think you could power the model with something a little smaller?? and it would still do the job if there is much smaller out there   question: if you know the watts needed but the motor seller only has the kv how do you work it out say the model is 3lb sports model so 300w on a 3s LiPo 12A - 18A esc how would you convert that to a kv on a motor????   RE: BUILD.   Got a little done today cut parts for Tail surfaces and the 2 fig of 8's F2 F3 and glued all together and finished Will post pictures tomorrow as soon as i get the chance.. build going ok ish so far. fus to start next i think   Adrian      
  16. Steve Lets see if i get this right or wrong   so on your maths then if we work out the vintage 75-80 rule i would need to do this 80W / 7.5V = 10.6A so i could do with a 12A ESC ? ? think thats woking in the right direction??   so prop size is really the main option and to test what feels / flies best for such a model just have to remember your low - big - slow .......high - small - fast idea but yes woking it out now sometime you just need some one to lighten the gray area to get the idea the way you have put it has helped immensely..   thanks again and can i add as friend on here please
  17. Steve Ty for the offer but i dont like to take advantage of anyones good nature,, will have a look in the model shop near me see how i get on , then if not and your going at all i may take you up on the offer, ty again. have you tried hobbyking at all are they anygood if so? have seen somethings on there i wouldnt mind trying out really looking for a simple and very cheap rc for test flying a little park style even second hand would do motor front.. so if my maths works well then .. if i get the motor Tim said about and the 2s li-po too then i guess it would work out 8100rpm with say a 10% loss for prop = 7326 rpm does that sound about right,??   i guess with anything electrical there is gains and drops all over the show, that and working out how to get the amps right for the esc thats another mathematicial matter to work on   will take a look at that link you have put in see whats on there , have saved it so can go there any time then.   thanks you AdrianEdited By Adrian Day on 11/01/2012 14:52:19
  18. Steve ty Great to get feedback from you and good information is hard to come by,   trying my best to make it look like the real design, and do Tim's model justice,   being a pain Steve would you happen to have a link for the tubing just so i can see what type you use, The one i was thinking is the orange one in the centre of this one from slecuk snake with yes the 1mm inside dont know if the snake intended would be any good as there would be 1 mm play, like the idea on the masking tape never thought of that, great tip on the li-po front was thinking the same thing as you have been told by some one who ordered from hobbyking that they had same problem, low price tilll they had to collect . I do try to get a lot from my main model shop in my town but not always possible (colin bliss models) then there isnt any postage or anything   on to the lb watts n kv) thanks for the info there i guess that the 100w is really only good for sports models then but say 55 - 75w ish plb for the vintage type would be more the norm depending its application ?????   am i getting that right? how do you change the kv into whats any Idea?? regards Adrian
  19. WINGS COMPLETED Nearly finished wings took this before I finished adding the last 2 gussets But have now fitted them so all done now onto the tail !! think they look ok???
  20. cheers Tim   trying to get used to the maths never really known all the info on kv / w so on , only working in the idea of 1lb to 100w but never know how to work out the power set amps or battery, thats something i will need to work on in the future,   thanks for the link that looks a perfect size for this model size and power and would go well with the motor u suggested ?   must have known as today i bought 100BBQ skewers for 99p cant go wrong   on that note i was thinking of running the wire inside a tube, such as a internal rod of a standard push rod if that makes sence, dont know if that would work but i know the idea your saying, even more food for thought??? what way would you think best Tim?   Adrian
  21. Hi tim thanks for all your help on the power side think i will go for the one i see and i have seen a 1300 on an american site but not sure on the cost of pnp, but it works out £3.80 for the li-po,   also if i put the LiPo more to the rear is it pos to put the servos inside the model with a fine metal push rod as in the size wire used to hold the wing rods to the hing???? well i have the wings finished today will take some pictures let me know if you think they look ok or not please ???
