Bought this as a BnF, flew for a while then one bad crash the VTX died. Decided to upgrade the VTX and RC Link to a TBS Unify Nano Pro32, and went to ELRS on the RC link with the Tinysled sled. The ELRS RX has the ceramic SMD antenna, no whisker or tee antenna to mount and get chopped and I've personally gone just under a mile on 250mw in the city with it. The Happymodel PP RX or EP1 would be better here as the DIY Nano is pretty thick. Word of caution though, the Tinysled VTX sled SUCKS. I had horrible video reception, rolling image, constant static, loss of color, etc and hard wiring it with some short silicone wire fixed that. ELRS 500hz on a toothpick is quite fun. You NEED to take off that PH2x2 connector and use a XT30 with a good 2s, it makes it fly like a totally different quad. The GNB 500mAh 90c 2s that FPV Cycle sells is perfect for the quad, I get a solid 6 to 8 min of flight time depending on how aggressive I am.

The stock Avan 2.5x1.9x3 props are okay, little too much prop wash for my liking. The Gemfan 2512 (2.5x1.2x3) props are the best for freestyle. The HQ T65 bi-blades have a lot of response but lack some grip. They are great for longer range cruising as they are super smooth, but I think they lack the grip needed for freestyle. I used a RDQ 650mAh 2s and got 15min of slow, steady flight.

The frame is really really stiff for the quad style, I was able to turn off most of the filters and leave RPM filtering on. This little thing is too much fun for how small and cheap it is and its great not only for first time drone pilots but also experienced pilots who want something cheap to bash around where their 4" or 5" might not fit.
