I would like to take this opportunity to discuss the charicteristics of a piped 2c. Doesn't putting a pipe on a 2c engine make the throttle transition sluggish?
A 2c with a properly setup tuned pipe won't be sluggish, but it will be more like having an "on-off" switch on the engine instead of a throttle. This is exacty why I don't use tuned pipes on 3D planes.
But don't confuse a tuned pipe with a Mousse Can Pipe. They are not the same thing.
.....a 4c has better over all transition authority? Isn't that what 3D planes need?
I agree that 3D planes need an engine with very good transition characteristics, but I don't agree that a 4c does it better. A 2c with a MCP will run and throttle as good or better than any 4c.
Not the blistering high speed's & horse power sluggishly built up from the supercharged effect of a pipe on a 2c, but the torque available at any position of the left stick that 4c's offer? I could be wrong here because alot of people use the piped 2c engine......
When it comes to 3D flying with a 2c, a tuned pipe is your worst nightmare.
But a Mousse Can Pipe is a 3D pilot's dream come true! A MCP can give nearly the same power boost as a tuned pipe, but without the annoying "on-off" syndrome. A properly setup MCP on a 2c will have a very linear and instantaneous feel on the throttle stick......almost like an electric motor.
Here's a link to a video of one of my planes. The engine is an old OS 40 FSR with a MCP spinning an APC 11x4. Crank up the volume and listen to how the engine instantly responds to even the slightest changes in the throttle stick.

Even the 40 LA will respond very well to a MCP, but the TT 42 GP just does it much better......especially for 3D and sport flying with one of the old Stickit type planes.
