85mm 2S Whoop | Track + Freestyle | Micro FPV

I used the 85X frame, BetaFPV 1103 motors, 2” 4-blade Emax Avon props and the guts from a 65 Pro 2 (FC and VTX-used different camera-see below). I used 2S 300mah BetaFPV LiPos and 450mah GNB with a proper XT30 connection. I get 3-3:30 on 300mah and about 4:30-5mins with the 450s. Overall it flys very well. You'll absolutely never get a washout since its so light (41g dry) and you'll be able to pull out of dives at the last second. This is hands down the best flying ‘whoop’ I have ever flown. I have tried a lot of different ‘recipes’ and this is BY FAR the best without a doubt. Build one for yourself and it will really impress you.

PIDs:
P(Roll): 60 I(Roll): 75 D(Yaw): 45

Nice ripping! Love that chimney proximity stuff

[teurisleonardo]

I have a beta 85 2 pro the beta 85x frame will work well greeting ??

[evekradiasi]

Can I use 500mah Battery to this frame?

[anthonylareppe]

Amazing :D
Thank you so much for sharing your knowledge and skills with those amazing youtube video !!!

[Spideystrat]

Nice! Just built an 85x. What camera did you use and do you prefer props in or out ?

[pleiadianpilot]

How, the, hell do you manage to get a whoop to fly so well man, my 75x, my cinebee, both fly like absolute shit on acro, washouts/yawspins/random flips, the whole lot 😫😫
