 Dana's Piccolo Pro Page. | This Piccolo pro is very agile! The Hacker B20-31S is very light, but packs a KV similar to Steve's 18L without the weight. He suggested I try the 31S. Steve runs his with a throttle curve, I prefer the steadiness of governed mode, having been spoiled by the Logo's Shulze and Kontronik setup. To minimize the possibility of a glitch recycling the ESC in governed mode, I've taken lessons learned from the Logo and tried to apply them here. Keep both ESC's as far forward as practical, and the Berg 5 in the metal shielding shadow of the motor. The antenna is kept as far away from the ESC's as practical. So far, it's been perfect, and I've flown it out further than I could comfortably see it. It's running perfect, and just a sweetheart with the CF blades. It's role in my stable is to act as the goat for 3D before trying the manouvers out on the Logo. To keep up with Steve, I'll be working on landing the Logo on the garage ceiling by this fall ... :) |

| NOTES on setup: For the reference, see Phoenix 10 Docs 9.1->Option 1 4V (don't want it to cut off .. ever..) 9.2->Option 5 Disabled (same reasoning) 9.3->Option 5 Brake Disabled 9.4->Option 3 Governor Mode Low RPM 9.5->Option 2 Standard Timing 9.6->Option 2 Soft Cutoff I have a JR X3810 TX, and for Normal mode set the throttle to 0,0, 41,41,41. The corresponding pitch curve is 25, 37.5, 50,75,100. I never fly in normal mode. This is just for additional safety (on top of the throttle hold at 0) in case I bump the collective with my jacket, trip the TH or something, so it doesn't activate until the second quadrant. The 25% minimum pitch is to have less negative pitch on startup, as it will have less load/drag than -12 deg would for a softer start. It's also the same pitch curve that I have for the throttle hold, which makes auto's a little more friendly in that it gives about -6 deg pitch max to help optimize head speed even if you panic and pull full negative on the collective. The throttle is set to 0 for throttle hold. If I lose the tail in flight, the reaction is to hit throttle hold to stop the spinning, and regain control of the machine for the auto, which has little room for error. Using Normal Mode to start up, first enable the tail with a quick hard left to initialize the ESC, briefly check slightly right rudder to make sure it's alive, mid stick the collective and let it wind up to the 1950. Once it all checks out OK, I flip to FM1 or FM2, depending what I'm going to do. |
