Hi guys,
Heres a couple pics of my latest project its a Ultimate 10-200 with all scale dimensions except for a purely pragmatic slight enlargement of both tail surfaces(not sure if it is neccesary having now flown it) This model weighs in at a little over 210 grams, cant tell you the wing loading because I havent bothered to calculate the wing area yet but it is 600mm span with a chord of 120 mm the fuselage is all depron, 3mm sides and bottom, 6mm top peices.The wings are 3mm with a 3x1mm strip on the leading edge of the top wing only, the struts are also 6mm depron.So far the only improvement I will be making is to put a carbon flying brace, diagonally from outboard bottom to cabane stut point because in a brain faid moment on the first outing I managed to make the bottom wing on one side break away from the interplane strut meaning that If I had pulled any negative G I'm sure that that wing would have failed, having no carbon in it.
the motor in this one is a little differant to the usual run of the mill 3D motor also, I decided to try an experiment and instead of the normal practice of high torque lower revving motor I thought I would use a Hand wound DIY 400 size motor with 14 turns of .5mm wire and a 7x6 prop, what I have is amodel that does not torque roll unless you want it to and it also has an almost instant throttle response. I'm very happy with the way this flies and looks in the air, it can be pottered around on very low thottle and do quite slow gracefull lazy eights or you can punch the Go stick and watch it zoom skyward.
Anyway I hope you like it, I look forward to hearing your thought on this little baby,
regards
Alexis
P.S that s my son Hamish holding the Ultimate, he flies too and says he wants one of these.

Nice project!
Models don't need to be flat! I recently built a Troll. Span is 770mm and AUW 198g. Powerded by a Typhoon micro 6/3D and 3s ePower 450HP. Performance is fantastic.

Thanks,
your troll looks beautiful, I have the troll plan here and have thought of building it a number of times but I always seem to do something else first, seeing yours sparks my intrest again.
regards
Alexis

Thanks,
It is one of the best slowflys I’ve ever flown, knife edge performance is stunning for such a small model: knife edge loops are very easy.
It just flies straight in any situation you put it, great for pattern style flying.
Hovering, torque rolling and high alpha harriers are also no problem.


I would definitely encourage you to build one!;)
