The airplane is about little bigger then a 40 size trainer.Th wing is semi-symetrical with alierons that have individual servos.I honestly don't think that wing is from this airplane although it fits perfect.But guy who sold it to me told me it was flown with supertigre 61,so i think 50 should be okay.Also i found that it says WHIZ40 on the side.I never paied atention to it but now it makes sence.
I was worried about down trust but since you guys say it's okay i think i will give it a try.Will have to break in my new engine ...Also i thinking of setting alierons on different chanels.Thats gonna be my first plane with flaps.Interesting.
Overall plane seems to be in a good shape so i hope it'll be more fun then spad trainer.
Thanks for the input,folks.
I really appreciate it.
