Oh, BTW, my Old Crow is not the one that Motion is offering. Mine is an Iron Ass version that came with a 580kv, which was adequate but not substantial. We also sit at 5000 feet above sea level, so that comes into play as well, especially in Summer. The 650kv really helps as well as the zip tie mod. Mine has the original sound system, when Old Crow was introduced, it had an upgraded sound system which didn't require a separate battery.
The new Old Crow, for lack of a better term, has an upgraded power plant/ESC and comes with a two blade prop, you have the option of purchasing a four blade spinner/prop system that is, essentially, the original Iron Ass prop/spinner with the Old Crow paint scheme, separately. I'm sure some of the guys are flying theirs with the four blade prop, maybe they'll share some info.
Lon replaced his stock ESC in his Iron Ass version and kept the stock 580kv and ran 5s with it and it performs great from what I remember.
I replaced my stock system with a 650kv and a 85A Mantis ESC but still have to keep a 1300 2s battery upfront to get the CG right (had lots left over from Ol' Weed wacker)
With My Little Gal I and II (both Iron Ass versions), they had no sound system and were lighter. Again the 580 was ok, but the 650 was better.
I personally haven't seen the new Old Crow fly but Mike and Ryan thought it was great, so, since I trust their judgement on this, give it a try stock with either preference for a prop(2 or 4 blade) before doing anything, I'm sure from what I've heard, it is definitely not underpowered.
My poor Old Crow flies pretty good with the 650kv, but what I don't like is the dead weight sound system battery, which I could conceivably eliminate with a heavier 6s battery ( I don't use the sound system as it sound like a great big fart to me!!)
I've seen CB's P-40 with the 6s system out of the FMS P-47, and man, it's almost better than sex!:PSo, much so that I bought Ryan's 6s system from his crashed P-47 and put it in my P-40.
So, I figure the same system in the P-51 would rock!!
Hope that clears it up.
