brfc7 Posted January 19, 2015 Share Posted January 19, 2015 Yes it's the red positive wire you remove so that only one of the speed controllers BEC's works. I run my Twinstar on either one or two lipo's which doesn't matter as the two esc's are on a Y lead with one positive removed. Ken? F16 with twin motors?

Stephen Jones Posted January 25, 2015 Author Share Posted January 25, 2015 Hi , I Found a 18Amp Esc today while routing for parts to repair my Transmitter . So i decided to take out the Flying Legends 20Amp Esc and give it ago , Glad i did . Wow they both now work perfectly and i am now pulling over 250 Watt and that was not a fully charged battery . So i now need to clean up the wiring and make a battery holder for the new battery , the best thing is , i will now be able to move the battery forward or back to archive the best CoG . So shouldn't be long now for me to get this one airborne . Steve Quote Link to comment Share on other sites More sharing options...
ken anderson. Posted January 26, 2015 Share Posted January 26, 2015 well done Stephen---- problem solved-make sure that the 18 amp one can cope with 250 watts...I may be wrong but it seems a lot for it-in fact too much...like I say I may be Wrong .... ken Anderson...ne....1 ....... may be wrong dept.

Stephen Jones Posted January 26, 2015 Author Share Posted January 26, 2015 Hi Ken , I have two Esc in my CanDoo one for each motor , and my readings are for both motors running together . 20 amp for the rear motor and 18 amp for the front motor . And zero torque . Should be Fun , i may put a smaller prop on the rear than the one i currently have on , as the rear motor seems to be providing more thrust than the one on the front . I may do a little more testing before i commit it to the Air . Steve . Quote Link to comment Share on other sites More sharing options...
Kevin Wilson Posted April 9, 2015 Share Posted April 9, 2015 Finally mustered the courage to maiden my CanDoo. That and procuring the services of a competent pilot (thanks bruvs). I can report that it flew away straight and level. No hint of the terminal left yaw suffered by some. I have fitted a Turnigy Aerodrive SK3 - 2836-1500 with a 7" x 5" prop. It is capable of 370W but currently drawing 190w with the 7x5. Even with my limited skills I find it easy to launch (1/2 throttle and a good throw) and is a nice flyer. I heartily recommend fitting rudders. For my flying style (sedate) having rudders adds to my control, although I cannot get it to stall turn.But then, being a canard, stall is not in its flight envelope. (Not photoshoped. one of my mods was a removable wing) I have now had a few flights with the CanDoo and am enjoying every one. Thank you Nigel for a very nice design Quote Link to comment Share on other sites More sharing options...
Cliff Bastow Posted April 9, 2015 Share Posted April 9, 2015 I fly mine regularly, it nearly always goes in my car on a flying day and its great fun. I did build it with the 4 servo set up so I could try all the mixes Nigel suggests but I find it more than maneuverable enough as it is .IE just elevator at the front and ailerons on the wing, so I haven't bothered with the mixes. I might give them a go if I can work out how to program them just to see what its like. Its a really great model, cheap and easy to build and a great flier.

Cliff Bastow Posted April 9, 2015 Share Posted April 9, 2015 I have two 40mm ducted fans lying around the workshop from an old model. Now what if I uprated them to brushless power and built another Can Doo? Hmmm there is a thought!

Colin Leighfield Posted April 9, 2015 Share Posted April 9, 2015 This is all good stuff, mine needs an hour or so of work to get it back to pristine condition, I must do that. As far as a DF version is concerned, I'm sure that Nigel made a reference to doing that. Are you watching the thread Nigel? Quote Link to comment Share on other sites More sharing options...
Cliff Bastow Posted April 9, 2015 Share Posted April 9, 2015 Hi Colin, You are right Nigel did mention a ducted fan version. I thought of sticking them on short pylons at the back like the A10. I think it would look good. No I must not get carried away I have to many projects on the go already!

Colin Leighfield Posted April 9, 2015 Share Posted April 9, 2015 Cliff, just like me. Too easily sidetracked, I must get a grip. Quote Link to comment Share on other sites More sharing options...
Cliff Bastow Posted April 9, 2015 Share Posted April 9, 2015 I know Colin, this year I am determined to finish one project before I start another. (its not going well as there are 2 models in build in my workshop as we speak) I must try to be more disciplined. All those free plans don't help! lol Quote Link to comment Share on other sites More sharing options...

brfc7 Posted May 18, 2015 Share Posted May 18, 2015 Had 3 flights with my Candoo today after suffering a slight prang on the 20th February. I'm running the suggested setup from 4Max (Motor / ESC) and with a 2200 battery I am getting 10 minutes flying and still around 30% left in battery baz Quote Link to comment Share on other sites More sharing options...
colisace Posted July 1, 2015 Share Posted July 1, 2015 Anyone done it wheels as I have taken mine to my club in Spain and of course there is no grass? Quote Link to comment Share on other sites More sharing options...
Stephen Jones Posted July 1, 2015 Author Share Posted July 1, 2015 No , But i do not see why not, just make sure you go for a tricycle set-up and the rear wheels just behind the balance point. Steve Quote Link to comment Share on other sites More sharing options...
colisace Posted July 1, 2015 Share Posted July 1, 2015 That's what I was thinking but wondered if anyone had tried it as I would think it may upset the flight characteristics. Quote Link to comment Share on other sites More sharing options...
colisace Posted May 28, 2016 Share Posted May 28, 2016 Finally plucked up the courage and fitted two wheels at the rear and one on the nose. Tracked in a straight line and rose off the ground beautifully. With a little trimming it flies great and feel as though it flies just the same as with no undercarriage. Landings are a little fast but who cares when landing on a concrete strip. Quote Link to comment Share on other sites More sharing options...

colisace Posted June 2, 2016 Share Posted June 2, 2016 Could find how to add text to pictures but the rear wheels are just held on with U clamps and a ply support on the wing top. The front wheel is an old tail wheel simply taped on for trials. It requires quite a run and does not want to lift off when suddenly it is away. It does have a nose down stance which does not help but requires clearance for the prop and landings are a dream. My next trial will be to fit an inrunner which was on the mig from RCM&E free plan with a 5inch prop to give better ground clearance and lift the nose up.

Stephen Jones Posted June 3, 2016 Author Share Posted June 3, 2016 Thanks for the info and pics, Much appreciated. I think i will try something similar , I tried To get mine ready to fly last weekend but i am still having problems getting both motors to run at the same time . I think i will have to take one motor off and fly it with just one motor on . I may try just one more time to get both motors to work if i can program my tx to operate the speed from separate channels as they will not work from a Y lead .

Kevin Wilson Posted June 3, 2016 Share Posted June 3, 2016 Stephen, have you tried an opto isolator on one or both of the ESC signal leads? These should stop any interaction between the two. Also I can see a possible interaction if the motor leads to the 2 motors are not kept seperate. Although in your model this should not be likely.

colisace Posted June 5, 2016 Share Posted June 5, 2016 Flew mine today in latest experiment. Used a 2700kv inrunner with a 5inch prop to give more ground clearance but required a small amount of weight at front. Took off great from runway and only required a small amount of extra up, flies great and now my club mates here in Spain all want one but want to try it in Depron so who knows what next is for the Can Doo?
