Trim Bypass and Thrust Tube
Hi Kevin
Unfortunately, I don't have the numbers handy at the moment. I will open up the kit we have and take the appropriate measurements. You have the 1700/2300 bypass with your kit. The kit also has the option of coming with a 1200 sized bypass. Testing with the 1200 bypass/thrust tube combination has shown minimal thrust losses with a SimJet 1200 turbine.
