I have a few of the EFlite motors, a couple of Power 25's, a Power 32, and a Power 46. I also have the smaller ones like the 450. I have them in two planes, the Mini Ultra Stik and the Mini Pulse XT. These perform really well and I've never had a problem. In the larger sizes, I seem to gravitate to the AXi's. I have a 2816 in an NES aircraft, can't remember its name at the moment, and a 2826 in an Electrifly Electrostik. I also have a few spare AXi's just waiting for aircraft. The highlight was winning a Gold 2826/10 at my club's annual dinner. I'm leaning toward modifying a Sig Rascal .46 ARF that I have in the box for the 2826. I've heard others have done it. My next project is to assemble and then install a 2808 in a Great Planes Spitfire.
