Can you give me your opinion on how much torque I need on a yak that is 71" and about 9.5lbs?

I was thinking of going dual elevator with 2 225MG's in the back. that's 132oz torque total.


what do you think?
Thanks!

i use 5625's on my 1/4 scale yak 55 they are fast digital and cheap(45 buck at troybuiltmodels)....watch out with the 225 mg and the 525 mg's ive have had a 5245 fail on me and a couple of 225s....after doing some research i found out its not just me
