i just recently purchased this beutifull bird and am confused on what engine i should use.for the first flights i am going to run a os 91sz-h but im not to happy generaly with its performance on a raptor 90 i had.i am running futaba 9452s on all controls and 9454 tail servo with an older futaba 510 gyro,also im running radix 69 cm blades on it with a cy muscle pipe.basically i removed it all from my raptor 90.any recomendations are appreciated as im not very happy with any of my os engines
