I did some test flying of my own on tuesday afternoon and Wendsday.
I got this little "Thunder tiger" Yak 54 from Hobbies in the hills a few days ago. Mine came with a motor so all I had to do was add an RX, servos and an ESC and I was away. There was the usual few hours taken to assemble it but no nasty suprises here, all was very nicely straight airframe wise and the hardware supplied was of good quality. Attaching the canopy to it's frame was about the most time consuming part of the build.
I didn't make many modifications other than add a canopy hatch as I could see my self searching for it in the swamp after it ejected, if I didn't. The only other deveation from the original recipee was the use of an 1800 mah 4s pack instead of the 2200 3S recomended by the manufacturer.
I tested the motor using an 11 X 5.5 plastic electric prop and happily noted that it drew 32A static and had a healty amount of thrust as well.
So off to McCoy field on tuesday afternoon, I put a little extra dubbin on my leather boots to help keep my socks dry but it wasn't realy needed the field was quite flyable.
This is a light model with generious controll surfaces so I expected it to be a lively one to fly. It took off in a very short distance, I reckon about 10 ft on around 3/4 throttle. It seemed perfictly trimmed in pitch and needed just a couple of clicks for the ailerons. I gave it two flights that afternoon as the light was faiding. The factory sugested C of G was pretty much where you'd want it.
Four flights on Wednesday, tho' it was a bit gusty the little Yak54 handeled the conditions with no problems at all.
It's a light stiff built up balsa model with a very healthy power to weight ratio, it's not extreemly fast with the prop I was using but it can move smartly if you ask her too. She will go vertical indefinatly and Knife edge with very little coupling. It flies like a much bigger model, realy nicely in fact. It's just what I want, an easy model to carry down to the field when the road is too when to drive in and one that is a lot of fun to fly as well!!
