r6dan Posted January 27, 2011 Share Posted January 27, 2011 What size motor do you lot think in this BRC say 250-300w but I think that is too small I think nearer to 350- 400, plus I think that they are tail heavy so a bit more weight might as well be motor and not lead...Edited By r6dan on 27/01/2011 21:00:26 Quote Link to comment Share on other sites More sharing options...
Simon B Posted January 27, 2011 Share Posted January 27, 2011 For a 3-D style performance i'd agree you'd want the 400w sort of range, as you'd want 150 - 200w per pound. Quote Link to comment Share on other sites More sharing options...
Eck Posted January 27, 2011 Share Posted January 27, 2011 Hi R6Dan, I've got one of these (Brilliant little kit!) I used a Giantcod setup (as usual) with an XYH 3536-110Kv motor, 60A SP ESC, 10x7 3-blade prop and Tipple 2300mAH 20C 3S battery. It still needs 60G of lead in the nose, so a bigger battery is a possibity. a brilliant wee flier - loops, rolls, inverted, knife edge - it does it all so easily!One bit of advice, though - if you fly off grass, ditch the spats and fit bigger wheels.Happy Landings!

Eck Posted January 27, 2011 Share Posted January 27, 2011 oh - and make sure the z-bends in the pushrods are at right angles - mine weren't and snapped one of the aileron horns! Quote Link to comment Share on other sites More sharing options...
Vecchio Austriaco Posted January 28, 2011 Share Posted January 28, 2011 I fly tyhis thing - even the 2nd airframe as I smashed the first one end 2009 flying with skis. As the first one needed some lead in the cowl I decided for a larger size engine - currently I use a Hacker A30L-14 - means 15sec peak power of 500W. I also changed the landing gear to a aluminium strip type which looks a bit more realistic. Yes, it flies the biggest loopings you want as it goes endless vertical.... - but the COG was spot on - not a gramm of lead. Have a look This was the first one a few days before it stalled (aerobatics with skis on are not always working... The only thing that servived was the pilot - he got a second chance and flies also the new one... Thats the new one - you can see the different landing gear Edited By Vecchio Austriaco on 28/01/2011 09:04:53Edited By Vecchio Austriaco on 28/01/2011 09:11:47 Quote Link to comment Share on other sites More sharing options...
r6dan Posted January 28, 2011 Author Share Posted January 28, 2011 I had to buy one! Do you think a closed loop rudder would be better on here to bring some weight over the c of g instead of having 3 servos flapping about in the wind right on the tail?

Eck Posted January 28, 2011 Share Posted January 28, 2011 Might well do, mate. I went with the original pushrods and rubbish horns! Quote Link to comment Share on other sites More sharing options...
r6dan Posted January 28, 2011 Author Share Posted January 28, 2011 It looks to be well built, still going around all the joints I can get to with some thin CA though, I have given up for the night!! need sleeps Quote Link to comment Share on other sites More sharing options...
r6dan Posted January 29, 2011 Author Share Posted January 29, 2011 I have used thin plastic hollow tube with 1mm piano wire in as snakes to put the servos in the fus,where they come out of the tube at the rear there is a slight bend in the wire as it exits the tube between where it attaches the control horns will a bend be ok ?Edited By r6dan on 29/01/2011 21:21:09 Quote Link to comment Share on other sites More sharing options...
ken anderson. Posted January 30, 2011 Share Posted January 30, 2011 dan-you may get a fair bit of slop(play) on tha rudder......i would have made a new exit nearer the surface of the rudder-prob just below the elevator hinge line....that's a lot of wire hanging out....... ken anderson ne..1.

r6dan Posted January 30, 2011 Author Share Posted January 30, 2011 Right changed my mind and going to put the servos in the tail, How do I set them up as it uses 2 servos one for each half of the elevator,how do I get them both going the same way on one channel?

Eck Posted January 30, 2011 Share Posted January 30, 2011 It needs a reversing y-lead. I had one from a model I bought from a clubmate, so I've no idea where to get one! Quote Link to comment Share on other sites More sharing options...
r6dan Posted January 30, 2011 Author Share Posted January 30, 2011 Can I butcher a normal Y lead? Quote Link to comment Share on other sites More sharing options...
Wingman Posted January 30, 2011 Share Posted January 30, 2011 No you can't alter a y lead - you need one of these Rev y lead They also have an adjustment pot to equalise the two halves.

Tim Mackey Posted January 30, 2011 Share Posted January 30, 2011 Or...use a mix to a free channel such as gear - then plug each servo into its own channel and use the tx servo reverse to ensure each one goes the right direction. Quote Link to comment Share on other sites More sharing options...
ken anderson. Posted January 30, 2011 Share Posted January 30, 2011 yes for the easy route i would go for tim's solution..........or the closed loop for the rudder sounded good ...with one servo on the elevator...... ken anderson ne..1.

Vecchio Austriaco Posted January 31, 2011 Share Posted January 31, 2011 Find here how to change a servos direction - after that you can use a normal Y-lead. Try it only if you are sure that you can solder nice small points and only if you have a small soldering iron. I use this solution im my Edge VA Quote Link to comment Share on other sites More sharing options...
Eck Posted January 31, 2011 Share Posted January 31, 2011 Just a wee warning, R6dan, I was flying my Edge around yesterday, "giving it the message" as our esteemed Chairman likes to say, when on the 5th flight, I was bringing it down for a low pass along the runway, and at about eight feet of altitude and three-quarters throttle, one of the grrrr snarl elevator horns pulled out from it's slot - the plane curved beautifully down to the runway for a perfect two-point landing on it's propeller and wingtip.The damage wasn't too serious - a broken prop, slightly cracked cowling and the wings pushed a half inch sideways!It'll be flying again this weekend, weather permitting!

r6dan Posted February 5, 2011 Author Share Posted February 5, 2011 Do you lot think a fixed rear wheel or a rudder steering one on the Edge?Edited By r6dan on 05/02/2011 17:10:28 Quote Link to comment Share on other sites More sharing options...
ken anderson. Posted February 5, 2011 Share Posted February 5, 2011 if it's going off grass strip-i wouldn't bother with steerable tailwheel on such a small model.......let the rudder do it for you.... ken anderson ne...1. Quote Link to comment Share on other sites More sharing options...
r6dan Posted February 5, 2011 Author Share Posted February 5, 2011 Well you know what our strip is like... I think I will fix it. Quote Link to comment Share on other sites More sharing options...
