Thanks again lthibault for your suggestions. I have completed my modifications and now have several days of flying and landing under my belt.
The plane flies great even with the additional 47 grams that were added to the nose. I was able to rebalance the plane by moving the the 5000mhA battery to the backmost position.
For the fun of it and extra cooling for the speed control while flying on hot Arizona days, I cut and screened in a NACA duct in the lower cowl.
Because of the short approach and short LZ at my favorite grass field, I still wanted to slow the plane's landing speed so I replaced the aleron Y cable with two direct aleron cables (plugged into Ch2 and Ch6 on the Rx) and programmed my JR9303 TX to drop both alerons (now flaperons) about a 1/4 in. while automatically adding about 1/8 in. of down elevator at the same time. I have timmed the deployment to take two seconds once the flap switch is hit...
Flaperons on this plane work great slowing the plane on final 5~7mph while still tracking straight and level. I do need to "fly" it to the ground because in really wants to float once it enters ground effects. Also, I deploy falperons at a medium speed... I tried it at a high speed and the plane wanted to climb.
For any interested parties, the Power 32 with CC60 Esc, 13x6.5 APC prop and fully charged 4S 5000mhA battery bench test on Eagle Systems Micro Logger at the following rates...
Instant Max Throttle: 62 amp burst (lasting less than a second)
1/4 Throttle: 1.74 amps sustained
1/2 Throttle: 6.36 amps sustained
3/4 Throttle: 21.84 amps sustained
95% Throttle: 46 amps sustained
100% Throttle 56 amps sustained
The Diamante is now as fun to land as it is to fly!
