Piers Bowlan Posted October 14, 2017 Share Posted October 14, 2017 Posted by THOMAS CUMMINGS on 14/10/2017 00:02:38: Posted by kc on 13/10/2017 18:01:19: The Harmony plan and all RCME, Radio Modeller, Traplet etc plans should be now be available from Sarik Hobbies Thanks for the link but I am unable to find the plans section of their website! Since Sarik took over the Traplet plans catalog quite recently their website has not been updated yet. You have to phone them - number on their home page. That set up looks a bit over the top Thomas, if you don't mind me saying so (unless you have scaled it up somewhat).

Peter Miller Posted October 14, 2017 Share Posted October 14, 2017 Thomas I never mind what people do with my plans. Lots have been converted to electric including a few Ballerinas. Just don't ask ME to do that. Javing said that I have just build an Easter Eagle for a friend. That has electric power.The original had a Speed 600. This one has the power train from Kitehawk and the performance is incredible. It climbs to a dot in the sky in much less than half a minute and then just floats around. This model really proved my theory about low aspect ratio wings for gliders Piers. Look at his figures. That model is miles bigger than the original which had a .20 in it and weighed about 3 lbs Edited By Peter Miller on 14/10/2017 08:14:04 Quote Link to comment Share on other sites More sharing options...
Dave from the future Posted October 14, 2017 Share Posted October 14, 2017 Posted by Peter Miller on 13/10/2017 18:23:48: The day that electric motors come with an IC conversion figure and propeller sizes I might consider designing specifically for electric. The Ripmax Quantum ones do. It's kind of missing the point about the flexibility of electric, but it gives a setup that presumably works.

fly boy3 Posted October 14, 2017 Share Posted October 14, 2017 Hi Thomas, I agree with Piers that's a big un lol. If my maths are right ( could well be wrong due to my age) I make it near a wing loading of 25 ozs/square foot. That is near a warbird spec. Are you going to fit flaps ? Cheers Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted October 14, 2017 Share Posted October 14, 2017 With a wing area like that 25 oz per sq. ft. is not too bad. Fly Boy The new owner of the Easter Eagle is so chuffed he is like a dog with three tails. On a dark and cloudy day he had a 40 minute flight on 2200 Mah battery.

Simon Chaddock Posted October 14, 2017 Share Posted October 14, 2017 Peter "...my theory about low aspect ratio wings for gliders." Interesting and more or less agrees with my own findings. My only caveat is that it only applies to smaller lighter planes both gliders and power! My super light (7.3 oz per sq ft) electric Depron Ballerina (with retracts but no folding prop) does a pretty job as a glider and thermals well too!

fly boy3 Posted October 14, 2017 Share Posted October 14, 2017 Hi Peter, that's my problem as an ic nut, when do you know when to come down with electrics ? Lol Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted October 14, 2017 Share Posted October 14, 2017 Simon: I went to a huge vintage glider rally some years ago at Tibbenham. IT was a lovely day and there was one massive thermal with a whole mass of high performance gliders going up. Minimoas and other really top class aircraft including the first ever glass ship. And right at the top and going up faster than the rest was...A Sedberg, also known as "The barge" Fly Boy. You know that it is time to come down when your neck locks in the "up"! position Just had a good afternoon flying and EE was there and coping with a stiff, gusty breeze.

fly boy3 Posted October 14, 2017 Share Posted October 14, 2017 Nice onePeter, can't wait for my EE maiden, still shattered trying to programme my Dx6i. for vee tails. Lol. Manual tells you what to do,but not how to do it? Cheers Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted October 14, 2017 Share Posted October 14, 2017 Yes, it can be a swine. Don't ask how I know But a few tips. Depending on the transmitter start off with either "delta wing" or "elevons". depending on what the transmitter calls them This allows you to use the aileron stick for steering rather than the V tailset up. Thye other thing. You may find that while you can get the elevators working the right way you can't get the rudders working. In this case swap the servos over so that the right servo is on the aileron socket on the Tx and the left one is on the elevator socket. or vice versa Even having recently set up the Kitehark and got it working on my very old Dx7.and then setting up EE which is the same we had to swap them over for the The new owner who has a DX7S and that was different. I can't comment on the DX6 I hope that this will help. It took him a while to actually grasp how a V tail works. If it is any consolation.I have set up several V tails on old Futaba FF8 etc and on the Spektrum I still get them wrong with embarrassing results such as trying to fly with them reversed. Ending up in a tree, Having to temporarily fly on the rudder stick etc. He also found that exponential made the model nicer to fly. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted October 15, 2017 Share Posted October 15, 2017 These are pictures from a video taken with a Mobuis camera on Alan's Easter Eagle on a breezy day Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted October 17, 2017 Share Posted October 17, 2017 Thanks very much Peter on help setting up the vee tail. Will try again on my Spectrum. Failing that I will revert to my trusty old Futaba still on 35Mhs lol. Exellent pictures from the Möbius, on the EasterEagle, my wife thought it was of the wide prairies in the USA. We can only see the tail of the EE, but as we know she is a lovely bird. Thanks, bird relates to model and wifey.

Peter Miller Posted October 18, 2017 Share Posted October 18, 2017 Which Spektrum do you have. Also which Futaba? I will then check the settings on mine. I still use my Futaba for things like gliders and vintage.as I have for more receivers for that than the others. Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted October 18, 2017 Share Posted October 18, 2017 Hi Peter, I am in same boat too with lots of stuff stil on 35mhz. I can only afford budget stuff, but my Fut. has never let me down. It is a Fut T6XP. and the Spectrum is DX6i. Thanks. Ps I will be trying out Orange Xs on Spectrum. Slightly off topic, sorry. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted October 18, 2017 Share Posted October 18, 2017 Hi Fly Boy. These days I don't buy expensive stuff. My Spektrum was one of the first in the country. Still going strong and as I said, my Field Force 8 is still used quite a lot, especially now that all my Spectrum receivers are in use. I always say if it works why scrap it.

Peter Miller Posted October 28, 2017 Share Posted October 28, 2017 Alan Wright who has the Easter Eagle has had a 40 minute flight and only uised power for 6 minutes. Then on Friday he was flying when he was on the end of the attentions of a buzzard. His Mobius video camera caught some great shots. In the second shot Alan was already in a steep dive to get away from a possible attack. Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted October 29, 2017 Share Posted October 29, 2017 Hi BBC (Forgive me if I don't type your full monicka, I am lazy!!) As the largest engine that I use is a .52 you will need to enlarge any plan. 25% sounds pretty reasonable. If you want something that is aerobatic and predictable and really enjoyable Ballerina is a great choice. Still my favourite model. If you want something quite a lot faster you could go for Super Marauder. THat has a .52 FS in it and is my windy weather model. Tell what you ideal layout is and I might have another suggestion Have fun Quote Link to comment Share on other sites More sharing options...
rgarde Posted December 12, 2017 Share Posted December 12, 2017 hello Mr Miller, I tried to find out which airfoil you have used for the grumpy tigercub as I maybe want to cut the ribs with my homemade CNC router. I think I have found the corresponding airfoil. Is it correct that you have used NACA2413 for the tigercub? Thanks in advance for your answer! With kind regards, Richard Quote Link to comment Share on other sites More sharing options...

Tony Cooper Posted January 3, 2018 Share Posted January 3, 2018 Hi Peter, I was reading your "Learning your lines" artical, It reads to me that there was a previous part last month. I have been searching but cannot find it. any clues please on how to find it? Cheers. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted January 3, 2018 Share Posted January 3, 2018 Hi Tony You have got me completely puzzled A) I cant find any article with that title in the last four issues of RCM&E And I certainly have not had an article published since October 2017 B) I can't find any record of ever having used that title in article that I have written over the years although the name could have been changed by an editor.

Paul C. Posted January 3, 2018 Share Posted January 3, 2018 Hi Peter , I think Tony is referring to the building techniques latest addition on the home page of this site. Just noticed it myself this morning 👍 Paul. Quote Link to comment Share on other sites More sharing options...
