This originally started with just the brushed board to get an acro x5c. Eventually added fpv (with OSD!). Later, when getting motors for my smaller brushed bills, I decided to cram 8520 53500 racer star motors in it. Had to use a Dremel to bore out the original 7mm motor holes. Removed the landing gear, clipped the brackets under the motor mounts, removed LEDs and the battery door for weight savings. Also, like my other brushed build, the higher c batteries helped a lot. It's interesting to fly, but the geared drives give it a real floaty feel, no matter how I try to tune my rates and pids. Don't know if I'd call it a success, but thought I'd share anyways.

Hi! Could you share your PIDs? I've been trying to get Betaflight working on geared-drive quads using the same flight controller you have here, but my tuning abilities are laughable and I can't stop them wobbling like crazy and generally being uncontrollable.
Maybe. A tiny whoop does pretty good around 100. I would think this would have more thrust and need less, except that the gearing makes it slower to respond, so it might actually need more p.
I'd start with 60, fly it 30 seconds, see if it feels good, check motor temp, and up it ten at a time until it feels good and motors don't get hot (warm is fine).
Now you got me considering replacing the vtx and trying this again. Lol

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

this is pretty much the raceflight phantom equivalent to a tiny whoop
I thought it would work out so much better than it did. It works, it's just not near as fun as I had hoped. I've thought about 2s, but the only 2s motors I can find are less than half the kv, do I don't know if it would do any good, especially with the heavier battery too
i put the 2s fc from q90c flying frog in my x5. i have yet to tune pids so with the stock micro's PIDs the motors would only fly 20 seconds or so before losing power and it wouldnt fly. it carried a 2s 450mah but like i said only fpr 20sec or so. maybe i can go into betaflight and up p and d to 100 or so and have success. i ordered a pitchplus 115 frame today and gonna try that on 2s with same FC on 8520s. The q90c has regular 720mm motors so 8520s should give me the punch i need to stay flying lol. without punch i hit stuff, hard.
