Not a lot to say here as you seem to know what your doing as you say the Yak has the same set-up as the Hurricane,if it were me i'd double check first and maybe use a watt meter just to make sure
Hobbyking (Durafly) does some sweet warbirds too now and my DH-100 Vampire should be on my door step some time this week

I wouldn't mind getting there monster Stang but i'm just waiting see if i can use a new field or not as my field i have to hand launch everything,but i'm keeping my fingers crossed as it is one hell of a sweet warbird and a good price.
I'll post a link to see what you think of it,good luck with your set-up but i don't think you will need it as long as you double check everything and just make sure it's not to nose heavy,still better than tail heavy
