Got out Wednesday with a few and got 4 flights in on my A-10 for the first time in a while. With our typical Spring winds being so strong for the last couple months, I had an opportunity to change my Mig-29 fans to the FMS 12 blade 3280-2100Kv inrunners (not that it need it with the TV nozzles) which added about 25% more thrust (have yet to get that up yet). I took the Mig fans (9-blade 3658-1920 Kv inrunners) and put them in my A-10 replacing the old outrunners (not that it needed it), which increased the thrust 15-20%. Talk about "Killing Two Birds With One Stone". WOW, really made a difference on getting off of grass and it's speed and vertical is outstanding. I've never flown it without all the ordinance, even on the maiden, so that's a testimony to it's incredible flight characteristics.
I had painted those swirly white things on the fan hub and the first time out RudyD54 asked why it sounded like an "angry mosquito" as in the Mig they sounded great. He checked it and told me the fans were out of balance, probably due to the painted hubs. It was vibrating so much my JHH pilot came down with his eyes crossed and missed the post flight briefing due to a massive migraine.
Well I guess you really can "teach old dogs new tricks" so thanks to gooniac33 and his outstanding fan balancing videos, it's now "quiet as a church mouse" 
except for the "whoose". Now if I can just figure out what all the hoopla is about over this thing called CG, I might be getting somewhere.
Anyway, I do have to say the A-10 is the best and easiest flying EDF I have. I'd almost recommend it as an EDF trainer and with it's large size, orientation is never an issue. Easy to see why it's been around for so long and continues to sell well while never having to be upgraded; what can you do to something that's close to perfect except mess it up. I had zero complaints with the stock outrunner fans, but the Mig fans are spectacular in it. On 2 SMC 6200's I have my timer set at 5:30 and come down with 38-40% in the tank, flying it much faster than scale. If I spend the flight more scale like, I can get over 7 minutes before my flight pack voltage telemetry indicates low voltage. Thanks to FW/MRC for keeping this one on the Flight Line. If this was a HH product, it would have been gone long ago (and the overall quality would not have been as good, IMO).
