There is a few different dynamax setups going on right now.
One is from: http://www.dyn-e-max.com/fan_kits.html
I think fred's Scorpion HK4035-630KV dyn-e-max setup would work pretty well... on 12s the fan is putting out like 4000 watts around 90 amps.. it's close to 2.5 pounds
I'd run each fan on 6s

Then there is the XPS/ Jetscreamer setup that is in development.. IMHO I think it's going to work well in larger models with higher capacity packs...the fan and motor are a whopping 3.5 pounds


I'm sure Tams super light fan would also do great also.. and on only 6s per side his fan sounds really nice at the lower watt levels.. I's say that's the best setup
His fan is under 1.5 pounds

I have the Stu Max and for a scale plane it will sound amazing!! I need to talk to Stu to see how his fan will do on just 6s per fan

Lot's of ways to do it.. and most of the fans will sound good at the lower watt levels this A-10 needs with two fans
I'd say 2000 watts per side will fly it really well... but I don't think any fan can do that on 6s...

even if the plane came in at 20 pounds with 4000 watts your only talking 200 watts per pound, with a jet I really like 250 per pound but you'd need more cells which just adds more weight ...
