What about GMS 76?
I need an engine in the 75 range for my Goldberg Chipmunk (45-60), I was thinking Tower Hobbies 75 but its out of stock until late march and who knows if it wont be delayed even more like it usually happen to be...
OS 75 is out of my budget and I want something simple because of dead stick reliability calculation, in addition the chipmunk comes with a cowl so its not gonna be easy to adjust.
Any experience with the GMS 76, should I wait for the tower 75, is there a difference between them?
How does the pitts muffler affect the motor performance?
Thanks
Alex
