Hope you guys don't mind if I chime in here, I certainly agree with Barracuda and by the way, nice nice looking birds there cuda. My first Heli was a Concept 30 with the supertiger engine many years ago until Xcell provided their 50 size nitro. I have flown both nitro and electric and really like both but for my scale stuff I always go electric.

The two reasons I choose electric for scale flying is the ease of setting a constant speed rotor system and the really cool harmonic sound you get out of the body. Gives a turbine sound and makes more decibel room for the rotor system to chime in with the blade sounds at a hover. I also love being able to hear the tail rotor on turns that I miss flying nitro but hey, thats why we have chocolate and vanilla right?  All of my builds are on the Trex and the FHH 600 airframes.

I use a 8S setup so I get 7.5 minutes of flight time. I fly for RC Aerodyne and provide build and flight videos and just happen to have a Hughes 500D I completed a few months ago. Thought you might enjoy a little peek at the 500.
