I'm no big fan of the jetcats. The fuel injectors run straight through the combustion chamber, construction methods of the chamber are more or less the russian variant rather than quality workmanship, and worst of all: jetcat ecu really jams into your radio. Crashes due to radio interference are usually linked to jetcat ecus. I've never seen an interference with a projet ecu....and if you excange the two, you will suddenly notice a much longer range on ground tests.
I dont know how it is in the states, but here in germany, jetcat pricing is also pretty high compared to other turbines...
I would go with FrankTurbines, SimJet, RAM, AMT (if you have the $$$) or similar.....generally speaking: if it is supplied with a projet ecu its probably a good reliable unit....
