Clay there is a review on here which is the Dave Patrick ultimate .40, or the Cermark ultimate. I bought one while on leave from the Army and fly it with an OS .50sx and a 12.25x3.75 prop. I honestly think a 4 stroke might get more torque to hover down on the deck, its hard to hold a hover at low altitude as it just wants to pull out of it. I will let you know how the experience goes though, the plane nearly met an untimely end with some engine problems early on which were since resolved. Be careful with engine choice as certain engines like the OS two strok will require a perry pump in order for the fuel to flow with no problems.

I will let you know as I fly it more and wring it out. Still programming it in my 9 CAP futaba. Here is my exact setup:

TX Futaba 9 Cap

RX hitec 7 channel rx
600mah 4.8v rx battery
4 x GWS mini servos (42oz of torque)
2x s3004 Futabas in Ailerons (had to modify setup to fit)
OS .50sx with bisson pitts
APC 12.25 x 3.75

Dave recommends a YS63, I am thinking a 13x4 Wide would work really well. I flew it on my plane once, but it loaded the engine too much.

Word of caution, this thing is bulit light, so be careful in engine choice. Fuel tank is tiny also. Landing gear is really weak and will bend easily, and you will want to throw out the wheels that come with it. I fly on a grass field so went to 2.25 foam wheels which caused me to lengthen wheel pant openings. Stock tail wheel is a real joke. I might add a heavy one to help the CG move aft for better hovering. It flys so nice now though that I dont want to change much. Slowing it down would help with 3d though. Thus far I have not been able to throw it around like a Twist or Funtana.
