Keith Simmons Posted July 7, 2011 Share Posted July 7, 2011 Looks lovely and best of luck for the Maiden. Can I ask what size 3 blade props you are using with your choice of motors? On Tony's website it's 11" dia (2 blade?) with 4max PPI 3657-1200 so I am interested in your setup. Thanks Quote Link to comment Share on other sites More sharing options...
Roy Thompson Posted July 7, 2011 Author Share Posted July 7, 2011 Hi Keith The plan is, to use gws 9x5 3 blade props. The motors are turnigy B36-56-09 1200kv.In theory they should draw about 30A each peak, not that I should need that much I hope. I'm scratching my head at the moment as to were to fit the air tank and valve assy. A couple of photos of the in side of Tony's showing the gear installation wouldn't have gone a miss in the original write up. Slowly ticking off the other jobs both. aileron servos are now fitted & working. Quote Link to comment Share on other sites More sharing options...
Tom T Posted July 7, 2011 Share Posted July 7, 2011 This is really good Roy, very interesting to follow! Can it be made as a nitro too? Sorry if this has already been asked and answered and I haven't seen it. Tom Quote Link to comment Share on other sites More sharing options...
Roy Thompson Posted July 8, 2011 Author Share Posted July 8, 2011 Hi Tom Yes It can, Tony has added details for an IC conversion on the plans (.15 - .19 ic engines) Quote Link to comment Share on other sites More sharing options...
Roy Thompson Posted July 18, 2011 Author Share Posted July 18, 2011 Still ticking off the final job's, not far now from her maiden. This is properly why the weather has turned to a big bag of poo Edited By Roy Thompson on 18/07/2011 22:08:54 Quote Link to comment Share on other sites More sharing options...
Roy Thompson Posted July 29, 2011 Author Share Posted July 29, 2011 Well the day came, I couldn't put it off any longer!All the jobs on the pre flight check list list were done, & the only thing left to do, was to get her in to the air I have a theory about first flights. The tightness of the bum cheeks is directly proportional to the man hours spent!! Quote Link to comment Share on other sites More sharing options...
Roy Thompson Posted July 29, 2011 Author Share Posted July 29, 2011 So how did it go? Very well for the first couple of minutes, the general model trim & control responses are fine. She needs a little more down thrust on the motors, but over all handling was fine. Then one of the motors came adrift!, & that cut the flight short. Unfortunately the landing was a bit rushed, coming in short & hard. Fortunately the only damage is a bent undercart. Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted July 29, 2011 Share Posted July 29, 2011 Sorry to hear of the undercarriage damage, but the great thing is it flew Well done Roy. Looks fabulous in the pictures, a real credit to you, wonderful color scheme.So you have experienced the worst nightmare of all multi engine models, one engine out CheersDanny Quote Link to comment Share on other sites More sharing options...
Roy Thompson Posted July 29, 2011 Author Share Posted July 29, 2011 If not for the engine mount being in front of the motors, then one of of the motors would defiantly been out, OUT and gone So came close! Quote Link to comment Share on other sites More sharing options...
Roy Thompson Posted August 3, 2011 Author Share Posted August 3, 2011 Well I got my courage up to day & took her out for her second flight, after much thread lock had been applied. This time the 5 Min flight was perfect (If I do say my self). A gentle 3 mph wind was blowing straight down the strip. So with fellow club mate Rob on the stopwatch we taxied out & turned in to wind, check list complete & rate switch set. Then with the throttle opened slowly, off she went. Up came the tail & some 20, 30 feet later she was airborne on about 80% throttle. The next few minutes were spent flying a series of circuit & figure 8's before climbing to try her slow speed handling. Much to my relief, there was no nasty surprise’s. The left wing will prop, but it was slow & quickly recovered. The first practice landing showed this again. So landing are to be power on affairs, with the model flown down on to the deck. This is exactly what I did on the next circuit, keeping about a 1/3 throttle on all the way down. This makes the landing approach seem a bit fast for my taste (maybe fitting flaps would have been a good idea), but she touched down gently with very little bounce & seemingly no tendency to nose over. With the speed bleeding off rapidly the tail sat back down with out fuss. The 5 min flight used 2.64Ah out of my 4.1Ah pack, so 6 minute flights should be the safe norm from now on, with a theoretical Max flight time of 7min 45seconds. Average power consumption was 352 W so that puts the average power to weight ratio at about 47 W/lbEdited By Roy Thompson on 03/08/2011 00:26:16Edited By Roy Thompson on 03/08/2011 00:26:33 Quote Link to comment Share on other sites More sharing options...

SA Allan Posted November 4, 2011 Share Posted November 4, 2011 Nice one Roy I wanted to build one too but the postage to South Africa was more than the kit . Picked up a topflite kit a few weeks back at the local hobby store for a really good price . Well done Quote Link to comment Share on other sites More sharing options...
P Smith 1 Posted September 8, 2014 Share Posted September 8, 2014 Hi am building this dc3 and am making the wing tips out of depron foam .. would it be advisable to build washout into the wing tips to prevent tip stalling??? Quote Link to comment Share on other sites More sharing options...
Roy Thompson Posted September 9, 2014 Author Share Posted September 9, 2014 Hi Paul The short answer is YES! Despite what Tony's says in the building instruction, you do need washout & plenty of it. I added about 1/2" under each wing tip, but I could have done with more. Don't get me wrong she fly's very nicely; just don’t let the airspeed drop! Fly the model on the throttles not the elevator & you should be fine. However if you let her stall she will drop a wing tip, & I find the best way to recover is to let her do one spin & then catch her if you have the height. So now I don’t let her low down, I keep the speed on keep her level at about ½ throttle & if I want to lose height I just back off the power. If you’re in the wing building stage, think about adding flaps. I dint but some time wish I had.

ken anderson. Posted September 9, 2014 Share Posted September 9, 2014 hello paul-check out our club web site-one of our lads made one and it was a bit 'iffy' landing...and loved to drop a wing-even doing so on take off if you lifted off to soon......it was to say the least not nice at all.....see the video...on our video page and contact the lad himself(old carry)Craig Carr for first hand account. His hair would stand on end when flying it-if he had any.... ken Anderson ne...1....DC3 dept.

Roy Thompson Posted June 25, 2018 Author Share Posted June 25, 2018 After a long layoff for repairs she’s back in the air, and ready for Middle Wallop. Luckily another club member had his new camera at the field Saturday, for her 1st post rebuild flight.
