Raceflight@8KHz / Multishot@4KHz - Canis Minor 4" Prototype

By 32bitsofGil on May 31, 2016

1 200 5

This build capitalizes on the speed of a lightweight racer, with the agility and responsiveness of a 4" Raceflight aircraft. Using 4" DAL tri-blades on this will pull a large amount of current, but the 20a seems to be taking the abuse. (I would recommend 30a, with a F390 chip)

This is a prototype frame at the moment and is the very first version. We are working on an updated version, but with the frame being as light and agile as it is, I don't think I'll be upgrading any time soon.

What firmware are you running on the Revolution board?

Interesting, I've been trying to test Raceflight on my revolution but I can't get it to connect to the configurator after flashing. I gave up for now but I may revisit it seeing that yours works. How does it fly compared to OP or librepilot (assuming you've used one of those before Raceflight)

I used OP when the CC3D was still a thing. OP is trash, just complete garbage when compared to a well tuned Raceflight machine. It helps to pair with the right ESCs running multishot. If you have trouble connecting to the COM port it's probably a driver related issue. I knew I had a few problems like that when I flashed mine because it actually produces two interfaces that accept separate drivers.

It's totally worth it though.

Interesting. Even with zigdag drivers installed and the revo in DFU mode, Raceflight still hangs on "erasing board". When I flash the board using the OP bootloader method, Raceflight fails to connect to the board after the firmware is installed. Not sure what im doing wrong but hopefully I can figure it out soon so i can try RF for myself. Thanks for the info.

Build a 5" Long Range Drone - Transformer Ultralight

Jun 21, 2021

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..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

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..
