EPP Foam Planes
Good Motors To Fill The Need For Speed???
I little while back I bought one the Cobra Race Wing Motors. The make them in a few different KV ratings. the Motor I bought was the CP-2814-1800. Below video is the initial bench test results. Here is link to where I bought the motor if anyone is interested: Cobra Race Wing Motors - Brushless Motors - Products (innov8tivedesigns.com)
Here is a video of the first plane I tried the Race Wing Motor on. I put it on my FF-Aurora foamboard plane. I killed it before I could get a GPS Speed run on it. It did look pretty fast though.
After trying the motor on the FF-Aurora I ended up putting the Cobra Race Wing Motor on my old FF-EPP Jet. The ESC I used was different and appeared to have trouble syncing with the motor at full throttle. That is one thing to note about the Cobra Race Wing Motor, it is a 14 pole (14 magnet) motor just like the race drone motors. When you have more poles the ESC must fire off many more times per revolution as compared to a 4-pole inrunner or even 8 or 10 pole regular outrunner motors. I hoped the 32-bit Power Up ESC I had would keep up, but didn't , at least with the settings I had. Maybe if I set it to higher timing it may. So if you are going to run a high pole motor with higher voltage/higher cell count battery, just know your ESC might not keep up. The best ESC's to use in this situation I think are BLHeli ESC's that are made for high pole motors. So I ordered a Cobra 80A Brushless Race Wing ESC that does have the BLHeli firmware on it. Stay tuned for that coming up soon.
I got the 80A Cobra Race Wing ESC and added it to the FF-EPP-JET. It worked out pretty good, which it should have as that is the specific ESC for these motors. The plane flew at over 130mph! This old plane is a bit of a handful to keep control of. The old servos and long control rods have a bit of play in them, combined with the torque roll it was a bit squirrely! Anyway it made for a fun and exciting flight! I will need to add this motor and ESC setup to another plane soon!
