Going turbine is such a different story, two 1000s would mean digital servos all around, stronger landing gear, all that stuff...totally different project. Better off starting with a new model.
The pitot fitting for the Ramtech is not ramtech specific, any of the fans can use either pitot or pipe pressure, and it's one of those "two schools of thought" things, I always used pipe pressure, but I'm beginnign to think pitot pressure is better because if the pipe comes out, you engine will still run. Just saw a freind do that the other day with a JHH hawk...something came off the airplane, I did not realize it was the entire pipe!
Is the BVM stuff that superior?
Hell, yes. The BVM fans and engines blow all the others away, by a country mile, more thrust, and much more reliable. It will be a little work adapting them Viojett or Viofan, because they have a slightly smaller diameter, but it would be worth it. There are bargains to be had on THEM, too.
