King....
Let me offer my personal experience with the evoJet Booster 90. We have been flying the 90 for nearly a year now and have more than a 100 gallons of fuel through ours, this engine just works! So many advantages to the Booster line of engines, the internal 12v Kero start just being one of them! Spool times are super quick and the ease of starting speaks for itself.... This is the choice we have gone with in our new Bandit.... Needless to say, I highly recommend them!
