Disregard the thrust readings for the MT57, they are lower than what is shown, I did the test on a very windy day and that really helps the readings. I have nothing to do with selling the engines, LS is a friend of mine and I did the website just for fun. I have to do changes to his website, but my computer had a problem so It'll be a couple more days until I can make changes. The MT50 doesn't have the power you need, the MT57 and MT62 do, LS is bringing in headers and canisters for the engines at a real good price for MT owners, I tested the canister it's nice, very mellow sound.

On my SD 260 I opened the back of the tunnel and now have a flow thru tunnel, it took 15 minutes and a piece of 1/4"x1/2"x7" balsa. Doing that you have very minimal cutting to the cowl, and great cooling.
