Try an APC 11x4, 11x5, 11.5x4, 12.25x3.74, and 12x4. See which one you like the most...

Engine acceleration is just as important as thrust if you're into 3D. I bet you end up with the 11.5x4...

You've got good taste in radio equipment!

I'm not sure what kind of pipe it is. It was on the engine when I bought it. It is a manufactured pipe and not a home made one. I was told some guy in California made it. I have it on my Morris Gee Whiz Bee and it will hover with ease and shoot straight up like a rocket out of a hover. I don't have a tach yet but but I can tell ya its screamin! Throttle transition is super fast. I'll try to get a pic of it up here later on today for ya. I have a Webra Speed 50 I just bought and after I get it broken in good I'm going to put a mousse can muffler on it. I'm hoping to swing a 13-4 prop on it.........................John

John,
thanks for the info.
alot of people in israel who own the webra engines say that this is not the suit engine for a fun-fly because it have a weak and bad throttle response.
my webra 40 respones very quickly.
i'm glad to hear that it works good on your morris.

I love mine. Im going to sell all of other engines and go all Webra. If everybody would try one out with a pipe on it they would love em. They are the strongest and most reliable engine for their size that I have ever seen..........John
