I dont have the engine yet. I have only the Senior Telemaster.

Honestly as you probably have already figured, I have no experience with gas, and havent even built a glow plane in about 8 years. I have been flying electrics for years and years now. I can tell ya lots of info on that but I have no idea of what sizes work when it comes to gasoline engines.

I thought I was on to a good choice with the BME because its essentially a .90 size, which is already larger than the .60 that is recommended for the Senior. I thought that would be pushing the sizing envelope in my mind.

I cant believe you guys suggest a 26cc motor, isn't that what they recommend for the 12 foot telemaster? On the HL website theres a picture that says a G-26 is recommended for the monster. But you guys know way more than me so I will start leaning toward those size engines instead.
