Hello Everybody

Many thanks for those repiles.

@BTerry:

I know that it is a bit "wrong" to buy a cheap engine and then add an expensive pipe. But, here in little Denmark, we have some very tight noiserestrictions, which does that the use of mufflers such as the one supplied with the DL-50 just isn't an option. So we have to use either a canister or a tuned pipe, to keep down the noise. A bit sad, but thats just the rules [&o]

About putting a bigger engine in the Katana, you are right, but wouldn't it be overkill? Maybe the plane would destroy it self caused by the vibrations from the 80 cc?
