RE: Best 26cc Engine
Oh, I just bought two FTL26cc side carb engines from HobbyKing for $300. I just got done running one of them:
7000rpm with a Turnigy 16x8 Cherry prop.
1740 idle.
This was after about 32oz of 32:1 Pennzoil Aircooled.
Good acceleration, seems very smooth, a vibe at 2700 rpm, but that my just be the harmonics of the plane it's in.
So it's not a world beater, but it is a very nice motor that is pretty cheap at $150 each, and they will be able to eventually power my Sky King Songbird.
