85mm 2S Whoop | Backyard Rippage | 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.
