I didn't know there was one either; it's below the engines forums listings, down in the mfg support forums.

I just got one of these engines (BT32EI) today, to put in a 1/4 scale Super Decathlon. Nice looking engine, and have heard good stuff about them, but never owned one. Couple of questions though:

1-the Fuji, and Tower, literature list both the BT24 and BT 32 as having 2.2hp. Why wouldn't the 32 have more than the 24?

2- why is there a shaft out the back; what else can you hook up to this engine?

3-Do you think using DuBro antivibe mounts would work on this engine, as shown in the picture below? There's a mount a little larger than the one I'm holding, made for larger engines. This mount would allow the muffler to clear the firewall without having to make a box (the rear shaft would also clear)

What size prop are you using and what's your performance like? I plan on a 18-6 for the Super D.
