Jett-Stream or UltraThrust Muffler ??
I have an OS FX .61 on a Cermark F16. I would like to get a little more zoom with the FX .61. I turn a 11x7 APC at 12,900 rpm with a Macs single piece muffler now.
Which muffler would give the best improvement, Jett-Stream or Ultrathrust ??
Thanks,
Bill

Tuned mufflers
Bill,
They are both well designed and efficient tuned mufflers, but they both cost three times more than they are worth.
They should sell very well, at a very generous profit margin, for only $15-$25, depending on where they choose to manufacture them.
But thinking American modelers will pay any price for something that works, they charge you more than the price of a low range .40 engine.
Buy smart.
