Made some changes, flew the 51 several times this Sunday. Flies well, easy to control. Landings without flaps are fast!
One change was to go to a 12x8x3 prop. we also measured the overall weight, and were somewhat surprised at the results!
The listed weight (7.5Lb) was evidently with a light engine, no fuel or retracts.
This one came out at about10.5Lb in ready to fly configuration. (Just had to measure the extra electrons, heh!
Sadly HH and H9 have discontinued the model. Due to the price of spare parts, I ended up buying one on E-bay, along with a discontinued H9 P-47.
There are significant differences between the discontinued H9 P-47 and the current "razorback" version.
If it wasn't for the higher price, I'd have opted for the new version. A major difference is the use of a wing tube on the new version.
The manual claims a weight of 10-11 Lb for the P-47. Hope that is correct. If so, a Power 52 motor and a 6C LIPO should get things done. (1650W Motor)
The current ESCwBEC is a Castle 75, and the ESC's short term capability is much higher than the 75A spec.
Note: The E-Flite 80a ESCwBEC has a note about the power 60 motor and compatibility. The 52 is very similar, except for the KV rating.
With the 52, the Castle 75 ESC will cause the motor to "screech" if the motor is stopped, and the throttle rapidly advanced from 0.
