hmmmmm, unless you are talking a brushless setup....the E-Starter is nowhere near as fast as an Aerobird. Just yesterday I was flying with my buddy ...I was flying much faster than his E-Starter. But he could easily turn inside of me.....had we been combatants...it would have resembled a Zero taking on a Corsair..... brute speed versus manueverability. If you haven't decided yet, perhaps you should check out the TigerMoth 400. It is much faster than the smaller TigerMoth. Greg Covey did a Review of the new Tiger and has a great video to watch....looks like tons of fun. I also have been looking to step up to 4 Channel E-Starter, Dandy Sport or the Tiger 400.....
