Shogun V2 - Feigao brushless - pinion suggestion?
I was given a Feigao 2045-3600kV brushless motor:
Size: 20mm diameter x 45mm length Shaft size: 2mm Weight: 62g(2.21oz) RPM/V: 3865 Internal Resistance: 0.0687 ohm Without load: 0.7A Maximum Amp Draw: 16A At this point the Shogun is stock. I enjoy controlling the ballooning effect in fast forward flight with the stock blades. I use wooden blades when working on a bit of 3D. My limited contact, with folks about as inexperienced as me, gets a variety of suggestions for the optimum number of teeth for the pinion, when the Feigao gets installed. At this stage I am a medium competent flyer, improving regularly. I will almost certainly do some mechanical upgrades before moving on to the next helicopter. Right now it might be most important to have a relatively cool running motor, and longer runtimes from the ThunderPower 2100s. I have a Phoenix-35 available to drive the motor. If you have a suggestion, would you also give your reasoning, to help me to learn? Thanks |

I would start with an 8 tooth. You want the motor RPM to be as high
as possible. That motor should be close to 40K RPM at 11 volts (as I understand the K/V thing). You are trying for a head speed around 2400+/-

"Self", I sez, "why not swing back by HeliFreak's one more time, just for sh!ts n grins".
Thanks jondbennett. Glad you came out of the woodwork, even if just for one post. Your comments agree with what i have learned elsewhere, along with the calcs I ran, but wasn't sure of. Keep twitching the gimbals. |
