Wasnt planning on sharing this initially because I feel like Im already planning a v3 but this thing really flies amazing and its a huge upgrade compared to the v1 1S Toothpick I built previously.

Changes In v2:

1) Ditched the Crazybee F3 board due to a bad 5v regulator and upgraded to the new BetaFPV 1S diamond shaped board.
2) Upgraded to a standalone cam/vtx setup from the AIO. Turned out to be the same weight but allows for 100mW transmission power, smart audio and the antenna is no longer in a vulnerable position (which means no more replacing).
3) Upgraded to EX1103 12000kv motors. These are much more powerful then the 1102s on the low end of the throttle and have similiar top end speeds.
4) Upgraded from Bi-blades to Gemfan Tri Blade 2504s. WAY MORE thrust and still whisper quiet.
5) Upgraded to a Powerwhoop connector from the stock folded pin 1S connector

Things to look out for:

1) Depinning and direct soldering moters to this FC is not for the faint of heart. Be prepared.
2) Ive had this FC reset on me 3x when plugging in a new battery and each time it requires that I totally reconfigure it in betaflight.
3) The integrated Frsky RX on this Betafpv board is SHIT use an external rx.
4) Higher power motors and bigger props eat at the battery life. Id recommend a minimum of 520mah 1s batteries which on average get me about 3.5min of ripping around

Current plans for v3:

1) Upgrade from PH2.0 connector to BT2.0 connector (more amps and increased mating lifespan)
2) Upgrade FC to Crazybee F4 lite with integrated RX/VTX (should save 2g + in weight)

No more struggling w/ the Power Loops!

try the gemfan 3018 tri blades on fpvcycle.com they only weigh a gram each compared to the hq 3x3x3 which weigh 1.5 each. and add about 60 seconds for flight time

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
