Hi everyone. Fairly new to the hobby and have been focused on larger aerial video multirotors, but have also done a couple cheap 250 builds. But as the local drone racing scene has been rapidly growing, I thought I'd put together something raceworthy. Here's a rundown:
Space One Formula 220X frame
Aikon 20 amp ESCs flashed with BLHeli_S 16.4
Emax RS 2205 2300kv motors
SPRacing F3 Evo
Tattu 3S 75C 1300mah lipo
Now to the problem. 1st flight using DAL 5045 3-blade props, the quad lifts no problem and hovers solid, but the second I give it the least amount of throttle, it just drops out of the sky. I doesn't disarm and the second it touches the ground, it's ready to take off again so I think I can eliminate any kind of signal issue
My first thought was just setup, but I've also tried F3 Mini, Naze32 and CC3D, all with exactly the same results so I think I can narrow it down to a power issue.
So I switched from the DAL 5045 3-blades to flimsy Genfam 5X3 two-blades and low and behold, problem solved nice and smooth even on full throttle punchouts.
I'd like to use at least 5040 3-blades, so I guess what I'm asking from the more experienced, is what in this setup is causing this. I know 4S is what 99% use and I've got some on the way, but even with these, ecalc shows that I won't be able to go above 5X3 props. I guess what I'm trying to figure out what component is causing the issue as I'm assuming the redbottoms are just pulling too much current draw. Yes I'm using 20amp ESCs but have 30amps coming. Just hoping to get a little input like - hey, that setup should work, you need to check all your connections or on the flipside - your problem is ___ and you need to change____. I'll post a pic of the wiring so you can see the setup, but it's pretty straight-forward. Thanks
