Built up the PC frame. So much stiffer than nylon.
Modded the cover so it can be wrapped around and attached with two small threaded screws…
This one has 10000kv motors.
Flies like a rocket, but battery life ain’t great! Think 8000kv may be the sweetspot - just not the Kingkong motors - they seem way too fragile…
Anyone got good 1103 recommendations?
I think youre right about 8000kv for 2s use in that size. I recently put my favorite prop, cut gemfan 3025 to 2.25" on to my first gen racerstar 1103’s. So now I have the same prop on dys1102 10000kv, eachine 1102 11500kv, and 1103 8000kv. The 8000kv by far has the best battery life and is almost as fast as the 11500kv 1102’s. 8000kv is now my go to for what I grab to fly first.
I highly suggest trying cut 2 blade 3025 props.
I’m too lazy to look, but is there a frame version out there for 0603’s? I (ahem) accidentally ordered 2 sets of 19k 0603’s and would love to try out brushless on this setup…ya know…for science!
I’m finding that for 2S light builds, 8000Kv is around the sweet spot for all motor sizes from 1102 to 1106, and cut down 3020 props, even 58mm (2.28") works very well (haven’t tried smaller yet). The 3020’s weigh 2/3 of the 3025 so might give faster response.
My own design inspired by the Boss.
Not as pretty for sure, but it’s as light, possibly better airflow for the props as thinner arms. Though the main reason I did this was to make more space for an easier build - I’ve fat fingers! I think it would even take a 20x20 stack.
