Peter Miller Posted May 29, 2016 Share Posted May 29, 2016 Glad you ike her so much,I know that I do. I was really interested that you had the CG at 1/3rd chord. I normally use 25% or 1/4 chord and never more that 30%. So I was interested that she had not turned twitchy and still recovered from spins instantly.

john stones 1 - Moderator Posted May 29, 2016 Share Posted May 29, 2016 No hint of her misbehaving Peter, comes in nice for a landing penetrates no bother, already one more built at our club, be no surprise if others build one. And Orange/Jacinth is a great colour for seeing John Quote Link to comment Share on other sites More sharing options...

Brian Jones 9 Posted June 27, 2016 Share Posted June 27, 2016 Here is my depron version of the Ballerina, covered with coloured packing tape. I hope you don't mind the few mods. Weighs 3lb 10oz inc batteries, and fly's really well. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted June 27, 2016 Share Posted June 27, 2016 Looks good, glad it flies well. I don't mind what people do. It is all part of modelling. The rear struts look interesting. Quote Link to comment Share on other sites More sharing options...
Brian Jones 9 Posted June 27, 2016 Share Posted June 27, 2016 Thanks the rear struts were an attempt to spread the load across the depron wing .they are probably too stiff really but it's all a learning curve! Quote Link to comment Share on other sites More sharing options...

bouncebounce crunch Posted July 3, 2016 Share Posted July 3, 2016 Loooking good. What is the verdict from the builder/pilot? Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted July 3, 2016 Share Posted July 3, 2016 Nice and easy to fly, good knife edge with next to no aileron or elevator needed to the left. My example needs trimming out some more as it screws out of outside loops, rolling to it's left through the bottom, maybe a balance issue or sidethrust? All it needed on the maiden was about 50% up trim for straight and level and a couple of clicks of right rudder for a vertical line on stall turns. For the second flight I moved the on-board glow battery back to the wing trailing edge which improved elevator response and reduced the up trim needed.

bouncebounce crunch Posted July 3, 2016 Share Posted July 3, 2016 That is excellent feedback from experience and good knowledge shared by Bob Cotsford. Thanks Bob. Haven't built her yet but she is on my list and your advice will make for a better build. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted July 3, 2016 Share Posted July 3, 2016 Hi Bob . Nice to know that you are happy with her. Possibly it screws out of outside loops because yu have a lot more power than mine.. Quote Link to comment Share on other sites More sharing options...

Possibly it screws out of outside loops because yu have a lot more power than mine.. You can't have too much Peter. Well, ok you can. I did wonder whether changing the prop from 12*6 APC to a lighter wooden 13*5 might help with less gyroscopic force and torque effect coming in when I open the taps at the bottom of the loop.

Peter Miller Posted July 7, 2016 Share Posted July 7, 2016 I am sorry to say that I will not be able to make it.. Due to an urgent change of plan by my club sec we will not be coming. Im sorry but in one way it is for the best. as I have also had a minor medical problem. Nothing serious but I would feel happier not coming.

Geoff S Posted August 26, 2016 Share Posted August 26, 2016 Well, better late than never. I took my Ballerina up to the airfield intending to test fly it, but I decided discretion was the better part of valour after a flight with my 'warm up' model - Riot. It was quite windy and gusty, to boot. I did 2 or 3 touch and goes, some better than others but it wasn't a pleasant flight and I was alone so no-one to take in flight photos. So it was mostly a photographic session: The fin, rudder, elevators and tailplane are all built up with laminated leading edges (except the fin). I made a mistake with the fin and fitted a piece of 6mm balsa at the bottom where it's mostly contained inside the tail side pieces with it's grain horizontal rather than vertical, which seemed reasonable. Unfortunately it meant the fin was very flexible and I lacked the courage of my convictions and braced the tail with closed loop wire attached to small brass brackets. I suspect the tail is still lighter than if it was made of solid sheet but even if not, I think the brace wires look quite cool as does the light shining through the surfaces. Hoping for a successful test flight later this weekend. Geoff Edited By Geoff Sleath on 26/08/2016 15:13:54 Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted August 26, 2016 Share Posted August 26, 2016 This one looks very nice Geoff! Clever not to fly when conditions are not good. Good luck with the maiden. Mine is still uncovered, will continue when autumn comes. Lucas Quote Link to comment Share on other sites More sharing options...
McG 6969 Posted August 26, 2016 Share Posted August 26, 2016 Very nice, Geoff. Really looking good. The tailplane flying wires give your bird a real 'Golden Age' look. You could have 'forgotten' to mention your mistake... Your driver also looks very 'casual'. Taking off for some holidays, I guess.
