It's still in the air and flying beautifully. I am running the 10 x 8 Master Airscrew prop. I know it's a prop for nitro but it fits my prop adapter and works well with the Dubro 3 inch spinner. I have a 3 blade master airscrew 10 x 7 I have not tried yet, again with a Dubro 3 inch 3 blade spinner. I have also thought about using the stock 3 blade with the Dubro spinner but it's working as is and since it's such a bitch to balance all that and get the spinner on just right so you do not warp the backplate tightening the screws I have left it alone. I did nose over a week ago and bent the motor shaft. (botched landing and hit on spinner) I had a motor shaft I had order from Grayson Hobbies on hand. It fit perfectly. Plane is smooth and fairly docile in the air.
I have read about using the 4s battery. If you do so I would suggest changing the ESC to handle the extra load. I have not tried it. I fly for 7 min on the 3s 2200 and that leaves me battery for approach and landing. I have some 3s 3000 but have not used them in this plane. I don't think the extra weight of the bigger batteries would be a factor ether since the plane needs nose weight. The 4s should make a significant difference in performance. I am ok with it flying scale and doing aerobatics that the actual P-51 could do. It is a beautiful plane in the air with the wheels up. If you get everything just right it is very smooth.
I just updated the receiver today and reset everything up. I got a Devo 7 transmitter with a Walkera helicopter and the transmitter is sweet. I am out of models on my DX6i so it's buy another transmitter or buy some receivers so I can use the Devo 7. The lease expensive route was to pick up a couple of RX701 receivers for the Devo. Now if the wind will just give me a break I am ready for a test flight.
