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!

Instead of 16:9 displays with a 32 degree field of view (FOV) the V2s now sport 4:3 displays with an impressive..

The FB 009 is a lightweight and compact budget FPV headset. When I first saw this I thought it might be worth a try. I'm never quite sure which headset to recommend at this price point, so let's see how this stands up. Most notably it includes a USB chargeable 1S 1200mah battery which is a decent capacity for an internal battery. The headset is compact and features a 3" 480x320 16:9 display. The..
