I was having similiar thoughts about the efflux velocity of the Supersport. I think I will have a word with Wren on that matter. As it's only a sport scale model I may just run a Wren single pipe between the twin tailpipes on the model if the bifurcated pipe is going to be a serious thrust reducer.

I see that Skymaster are now recommending a minimum of 20lbs for the F18 on their website although the magazine ads are still at 14lbs.

Thanks for the input guys.
