Well, here's an update-Chief said the Extra 330's were "on back order", which kind of pi$$ed me off since they didn't bother to tell me that on the phone-SO-I cancelled my order and got a GREAT deal at my LHS on a SU-31 (Hangar9)-out the door for $725 plus tax!

I thought that was too good to pass up.

Then went out to the field to watch a Hangar9 SU31 and the BIG Ultimate fly, I was impressed.

Ryan-that 3W 106 shakes pretty bad, and is 2 times as much power as that SU31 needs-I'm leaning towards the ZDZ80 single, I was just wondering how "user friendly" it is since I have no exp. with this line of engines. Where's a good place to order one?

Thanks
