engine for hobbico extra 300S
What should be the perfct engine for hobbico extra 300S- super tigre 91, Tower hobbies 75 or O.S. 61 FX?
The super tigre is the powerfull one, the T.H. 75 is the cheapest , but I think they can't beat
the reliabilty of the OS, and it's power is enough for this 40-60 airplane. What do you think?
