FIIshTank (Hoverbot Ultralight Prototype)

I really want a quad that I can fly indoors (possibly on 1S or 2S) and then take it to the back yard and have enough thrust to work on tricks when I don't have time to go to a park and fly the big 5" quad.

I've been looking at brushless micros, and the pepperfiish build looks very interesting, but I really want a frame with some reasonable prop guards.

While looking for a frame with 16x16mm mounts, I learned from the fpvchat slack that the awesome guys at Hoverbot are up to something new. I couldn't wait to try it out!
This build uses the Hoverbot Ultralight Prototype frame, and is just 7.3g with prop guards. The wheelbase is 80mm and is for 2" props.

I wanted a durable cloverleaf antenna, so I'm using the IBCrazy Cloverleaf, which is 1.1g when trimmed down (vs .6g for a whip).

For the 3d printed parts, I got the spacers printed in TPU, and I'm using the 20* camera mount printed in ABS.

I compiled a huge list of 2S batteries at
But ultimately I've decided to go with these:

I fly indoors with 2S and a throttle curve to make that sane. Full throttle 2S indoors is a bit too much oomph for my skill to keep it out of the ceilings. OpenTX config for telemetry alarms for 1S/2S as well as a switch that enables 1S / 2S "indoor mode" / 2S mode. Indoor mode has a reduced linear throttle that hovers at 50% instead of 30%.

AUW with my ghetto 1S is 52.6g, AUW with the 2S 300mah is 54.7g. AUW with my go to 450mah 2S battery is 61.1g. Those 450mah 2S give me ~5m30s flight time indoors!

The more I fly this quad, the more I love it. I've not touched the tiny whoop since.

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..
