Removed all the gear from my X2 Elf because it was just too heavy for the props and felt like it was always working hard just to stay off the ground : https://rotorbuilds.com/build/4862

To recap parts:

This build was much easier with the extra room and feels a lot more solid and less compromised. Final weight of the quad is 65g without battery. 2s 500mah is 33g, 2s 950mah is 48g, 3s 450mah is 40g and 3s 460mah is 50g.

After the maiden I can say it does everything I want, hovers on lower throttle and is much better balanced. It is running BF 3.2.0 with stock pids dynamic filter, all notch filters off and no oscillations - something the old elf 88mm struggle with on much lower Ps and Ds. Motors warm on 3s and no more so very happy.

3s does make the battery sag a bit so need to try the gemfan 3025s. Minor quibble though, on the whole I am very pleased.

Got given a free life on the build - reduced height between FC and ESC and shorted a motor wire on underneath of the receiver pad. Killed the 5v receiver trace but all I had to do was wire to a spare 5v source (LED). No harm otherwise, phew!

It's shaped like a video game controller but has all of the functionality of a traditional transmitter like the Taranis Q X7 or the Taranis X9D. It features OpenTX and supports most..

The Bannilite was a collaborative effort between Luke Bannister, AKA BanniUK and Falcon Multirotors. The Bannilite features ample camera protection, easy arm replacements and weighs in at only 72g. It even includes a spare arm and camera mount. It's an excellent choice for FPV racing and doesn't break the bank. The goal of this build was to feature a number of modern FPV luxuries including easy..
