How did you manage to fit the hakrc aio between the standoffs. I've got one of these aios and decided it was too tight and ended up using a Happymodel Super F405 HD with integrated elrs

[@vietmove]

Why not, it has 20x20 and 25.5x25.5 mounting holes, a little bit difficult with battery wire but all is ok

[@MadfishFPV]

@@vietmove sorry I posted this and slapped my head after , I was thinking of my Flywoo Goku 20x20 aio

[@DINSTAAR-FPV]

Very nice! ❤

[@gregdavidd]

Very cool thanks for testing this. You dont think that those 21700 are too heavy for the 1404 motors? I wonder if you could get close to the same flight time with 18650s?

[@vietmove]

Its a pity I dont have 4s 18650 vtc6 3000mah, i have 6s2200mah 18650 but i havent tried it yet, its got 6min with 6s850 and 9min with 6s1150.

[@gregdavidd]

@@vietmove OK. Thanks for responding :)

[@MadfishFPV]

I've got 13min15sec with a gnb lihv 1100mAh 4s but that was till the battery was below limits. 10min easy, and that's a sub250g build with O3, GPS and finder

[@chrisbee5481]

On 4s 18650 I get about the same flight time. So the weight is too much

[@MadfishFPV]

@@chrisbee5481 what flight time do you get?

[@MazAFends]
