GP Ultimate 1.60 Power options
 

I am going to order the GP ultimate todayto replace my Ultimate, (crashed on maiden flight with Goldberg 10 dash 300s) Cold weather (20 degrees) seems to affect JR servos?
Any how, does anyone have one of these planes with the OS 1.60 engine? Or the Saito 220?
I dont want to go to gas engines yet and need some advice.
Any input is greatly appreciated!:D

I have used the OS 160. The engine is great. Ran flawless. Response and power were fantastic !!!! I like Saito as well never used the 220 You cant go wrong with the OS 160 you be glad you choose it


Good Luck
Chris
