RE: No more Ultra Thrust?
I just spoke to Dave today when ordering some props and such and didn't think to ask about the mufflers. I did ask what he was going to do now that Nelson quit making engines and he said "retire". Makes you realize how small our hobby really is when one person decides to stop making something and it changes the whole program.
Jett mufflers are just as good, but I wonder if he will be able to keep up with demand.
