I have a J-Munts Merlin 140 in my Ultra Flash and it suits it just fine.With 31.5 lbs of trust it will do 250mph as wedo not have any speed limit here in the UK.

But thats not the mainreason for using the M-140.This turbine is very well constructed and is smaller in diameter and weighs less than a JC 140. I have no nose weight to get the balance correct.It is also very economical and 8-9 minutes is easy with variable throttle use and the using the main and wing tank. Gaspar is also a very helpfull guy and gives excellent service.
