I wanted to see how a super light weight 85mm 2S whoop would fly. I used the 85X frame, Happymodel 0802 motors, 48mm tri-blade props (lightest weight since the motors are so small) and the guts from a 65 Pro 2 (FC and VTX-used different camera-see below). I used 2S 300mah BetaFPV LiPos with a proper XT30 connection. Overall it flys very well. You’ll absolutely never get a washout since its so light (32g dry) and you’ll be able to pull out of dives at the last second. The downside of this build is that you need to drill holes in the 85X frame to fit the 080X motor mounting pattern. I wanted to use the BetaFPV 12,000kv 0802 motors but the wires were too short and I did not feel like lengthening 12 hair thin wires which is why I ended up using the 16,000kv Happymodel motors. The downside to the 16,000kv motors is that they are a bit power hungry which resulted in 2:30-3 minute flight times. I have since swapped out the 0802 motors and 3-blade 48mm props for 1103 11,000kv motors and 4-blade Emax Avon props. The result was that I got a bit more instant torque/punch and more efficiency. I have a video of the 1103 version that I will release soon!
VTX: from 65 Pro 2 – Not available for purchase on its own at this time.
Camera: (as seen in this video – not very good) https://www.banggood.com/Super-Mini-1000TVL-FOV120-Degree-14-CMOS-2_8mm-Lens-3_3-5V-FPV-Camera-p-1175721.html?rmmds=search&ID=44069&cur_warehouse=CN
I have since swapped out the camera for this one which is much better: https://www.amazon.com/gp/product/B072X72W4P/ref=ppx_yo_dt_b_asin_title_o02__o00_s00?ie=UTF8&psc=1
