Gary,
I personally run Scorpion on all my machines, Based off of what Alan mentioned, if you are in the Market for one, I have 3. To add to that The Hacker is a very Quiet running Very Efficient Motor for Sport flying, and will handle 3D without any issues. The only limiting Factor is Pilot Skill Set. If you are a 3D smack down kinda guy, Buy the Scorpion. But if you are Budget Limited then the Scorpion is a Great alternate. I like them both, and based on the Machine that I build and the type of flying I do, determines which power plant I install. For my scale birds, I run the Hackers. When I'm letting it all out and in the zone, Nothing gets me to Ground Zero quicker than Scorpion!! They really take the Impact Well
seriously It is a nice Piece of craftsmanship for sure!! Either way you go, You cant go wrong.
As for you Alan, I'm gonna give you that one for free! lol I'm tired from a drive to come home and ship a bird to another New Synergy Family Member, and drove back to Savanna Georgia this morning at 1:25 am to go fix a real Heli.. Next fly in, Check your Boom supports.. LOL
Best Regards,
Kevin
