GP Yak with a Moki 1.80. BCM Pitts... This is the perfect match. I've been flying it for over a year now... If you have any specific questions shot me a PM.
Also other planes that I have Moki's in that perform perfectly
Moki 2.10 - RC GUYS Super Decathlon ARF
Moki 2.10 - Top Flight Giant Scale P-51 ARF
Moki 1.80 - CMP Giles 202 ARF
Here are the only pics I have here at work. I will post more of the others if you like

Here is one for size comparison.
