RE: New .90 gas engine (15cc)
You know, this thread really sucks. The majority of the posts have nothing to do with this specific engine.
Anyway, This engine will work perfectly in replacing a .60 sized engine. I have one in my Pica FW190 and it is perfect really. Again, I am having the same reliability issues. I have only had one flight that did not deadstick. I think it might be my small tank. The internal hardware just needs more room to move around.
Please try to keep this thread on topic.
