I have a Brio since it was new in 2006. Converted it last year to a Himaxx 6330-210, CC Phoenix 80 HV, APC 20.5 x 14. A great combo . Previously, it had an OS 140 RX piped. The ship is approaching 400 flights( 97 with electric) and I highly recommend the conversion." Anthony RCU" gave me some encouragement and advice . What he says about tight quarters for loading batteries is true, but it isn't too large of an obstacle.

I had mine out last weekend in some stiff crosswinds- the performance is very satisfying. Much, much more power with this set-up than glow.

Its on the heavy side, but not a pig. I'm using Gens Ace 5300 5S bricks which are heavy, but very robust. Remember to make provisions for entering/ extracting cooling air and you'll be fine.

The Himaxx 6330-210 has worked out so well that I've installed one in my new Griffin.
