Stephen Jones Posted December 23, 2010 Share Posted December 23, 2010 Hi fellow wood worms , I have started a build and Design project to keep me busy over the cold winter months . Not sure if anyone has built a radio controlled model of this type before and as i like the shape of the fuselage i thought id give it a go . Its a two part project as i intend to build a small 24" model 1St as a gentle flyer for summer and a Larger 36" model for faster flying . Here are some pictures of where i am at the moment . The start of the small 24" model , the Fuselage A vac formed canopy would be nice . Not so bad me thinks A nice size hatch to gain access to radio gear . I was going to put a small ducted fan in but now decided on a pusher prop instead . I may try a Ducted fan at a later stage . I have one more wing to build then its a case of getting it all together . Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted December 23, 2010 Share Posted December 23, 2010 Looks interesting,has it been ,a puffed up one,at the christmas pudding already,looks a bit like a fish,is it called nemo Quote Link to comment Share on other sites More sharing options...
Wolfie Posted December 24, 2010 Share Posted December 24, 2010 Steven, this is the 'Optica' design that you discussed in the EDF thread I assume? Will you be using a duct around the prop too? Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted December 24, 2010 Author Share Posted December 24, 2010 Hi Wolfie, No this is not a Optica , I don't recall Mentioning Sipa 200 before . Other than in a thread called " wot is this iam building Where someone did suggest it might be a Optica . And it would not be a Sipa 200 with a duct around it . Although you could also argue its not if it is prop driven . But for now will do , as i have seen many jet models prop driven that still look ok . Hope this helps http://www.machdiamonds.com/s200.htmlEdited By Stephen Jones on 24/12/2010 16:28:01 Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted December 24, 2010 Share Posted December 24, 2010 Now, isn't that a sweetie! I know very little about EDF's except that it would probably need oversize intakes in order to go down that road, so the pusher prop seems like an excellent approach. tim Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted January 1, 2011 Author Share Posted January 1, 2011 Hi again , A few more pictures still the small model yet again . The motor is small but fits nice , I chose this motor as i have a smiler set-up in two other models . One is a converted Epp foam glider which flys very well on less than half power for approx 4 flights of about 7 minuets each . and the outher model i have is a depron bird . both set-ups use 4.3g servos 2off a small 35Mhz receiver and a 350mah 2s battery thats why i thoght id build this so light .

Stephen Jones Posted January 3, 2011 Author Share Posted January 3, 2011 Hi Again . Some more pictures , Just need to make the wing-tips add covering and the radio gear .The weight at the moment is 78 Grams . Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted January 7, 2011 Author Share Posted January 7, 2011 Opps , I got a bit carried away with the hot air gun . Not shore weather to start a new cockpit , leave it or try and re-heat it back into shape with hot air gun and maybe a balloon in flated on the inside to try and get it back into shape ? .

Stephen Jones Posted January 19, 2011 Author Share Posted January 19, 2011 Hi ,Pictures of my 1st attempt at making my own moulded cockpit . Not so good on this side .Looks as though i will have to seal the foam in some way before i try again . Quote Link to comment Share on other sites More sharing options...
Dave Wilson Posted January 20, 2011 Share Posted January 20, 2011 Come one SteveHurry up and get it done.... It's going to be a nice weekend so let's see it down the field flying...... The cucumber flew, this should have no problems Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted January 20, 2011 Author Share Posted January 20, 2011 Hi Dave , So what do you think how it looks just get it done , bear in mind this is only a small model and is being built to aid an insight on any modification that may be needed in the larger version . And intended for summer flying where it could land in long soft grass . ?Edited By David Ashby - RCME Administrator on 20/01/2011 20:43:12 Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted January 20, 2011 Author Share Posted January 20, 2011 Hi Dave , I will finish of the covering . And now that i have the radio gear shouldn't take too long its just the cockpit doesn't look so great .

Stephen Jones Posted January 22, 2011 Author Share Posted January 22, 2011 Well its covered and only weighs 116grams without 350ma battery and needs linkages fitting . Nearly time to tuck into the meat and gravy and build the 36" model . Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted January 22, 2011 Author Share Posted January 22, 2011 Well dave , I dont think this weekend is going to be such a good weekend with all this frost . Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted February 10, 2011 Author Share Posted February 10, 2011 Hi , Hopefully will be able to get a move on with the 2nd part of this build project now .I have had my plan enlarged at the printers and made some minor changes to the wings as these will now be sheeted . Haven't made my mind up as to how best make up a battery box or if to fit under carriage fixed or retract .

BalsaBasher Posted February 10, 2011 Share Posted February 10, 2011 Hi there Nice project , would it not make sense to test fly the smaller prototype first ? Before committing to building larger version ? Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted February 10, 2011 Share Posted February 10, 2011 Fascinating stuff Stephen, looking forward to more pics Cheers Danny Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted February 10, 2011 Author Share Posted February 10, 2011 Hi again fellow Wood Worms , Small update booms done . Top fuselage i wasn't going to plank but wot the heck went a head with it anyway . Will be starting on the lower part now . I have now decided to build the fuselage in two half's to allow easy access to get the motor in , and fix the wings into place . Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted February 11, 2011 Author Share Posted February 11, 2011 Hi BalsaBasher , Well we haven`t had very good weather for test flying the Very small model and although the same but in different size the V-small model is built very light and is for more relaxed flying in calm summer weather , where as the small model is built for more ( hopefully ) fast and aerobatic flying , As the original plane was meant as a Jet aerobatic trainer . That's why i have decided to go ahead with this build , Plus i could be waiting forever for the right conditions as i usually find i`am having to work when we do on occasion have any good weather Wing skins cut and marked ready for tomorrow and belly of fuselage ready for planking . Hopefully will have the wings built tomorrow along with the fuselage Edited By Stephen Jones on 11/02/2011 00:38:57 Quote Link to comment Share on other sites More sharing options...
BalsaBasher Posted February 11, 2011 Share Posted February 11, 2011 Thanx for reply Stephen , fair enough . We have also had endless rains in SA recently and this seriously curtailed any flying.How will you finish the model seeing that you are going for sheeting ? Fiberglass ? Or Film ?

Stephen Jones Posted February 13, 2011 Author Share Posted February 13, 2011 Hi BalsaBasher , The build has come to a stop due to other things coming up hopefully will be back on track soon . I haven't decided how to finish it yet , will have to see how heavy or light it is first ,Possibly spray painted no idea wot colour scheme to do either .

Stephen Jones Posted March 14, 2011 Author Share Posted March 14, 2011 Hi Guys , Sorry its been a month since my last post i have not given up on the project . However i do seem to have developed an allergy to either the balsa ,dust or super glue or all of them .As i went to bed with coughing fits and breathing difficulty after my last post . i decided to stop modelling for a while . I then tried just a little more last week with the same result .So it is with great regret i will not be doing any more modelling until the weather is fine enough for me to sit outside with a dust mask on . i am still coughing and have a layer of mucous lining the inside of my nose i dare not go any where near any dust for a while . This is the little bit more that set me off again . I have since looked at more photos of the Sipa 200 and come to the conclusion that the fuselage is not correct . Although it looks right in profile from the top , bottom and sides .Closer in-specification shows a flatter bottom and sides on the fuselage , and the top of the rear wings where it meets the rear of the fuselage also is flat . So i may alter the plan for a next build depending on how my health goes . Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted March 15, 2011 Share Posted March 15, 2011 Really sorry to hear about your health Stephen, thats a real bummer. Its not fair when we can't do a thing we love. I thought I had a similar thing last year, and bought a really good quality mask and filter. I wore it for a while, but it was just so uncomfortable. It seems to have subsided now and I am back to my old self. But now I always have an overhead fan turning when I am gluing and I have learnt to hoover rather than blow the balsa dust off the work. Just those steps have let me get back to the bench. Take it steady for a while, and hopefully your tolerance will return.

kevin wild Posted March 15, 2011 Share Posted March 15, 2011 HI sorry to hear about your allergy, get back to it as soon as you're well enough the Sipa is a lovely aeroplane and your design thread is a great read keep it up Quote Link to comment Share on other sites More sharing options...
