Yes, it is a BIG engine. It would go vertical at a little over 1/3 throttle with it, spinning a MA 18x10 at 7400.
The MDS turns an APC 17x8 at 9100.
The air scoop, hmmm... Oh, I haven't mounted it yet. Need to oder a new cowl, the MDS fit's completly inside the cowl and doesn't need the large vetilation hole in the side of it.
Sorry, alerions servo's are digital 9625's. Battery pack is 6v.
