This here (left) is my first Brushless Tiny Whoop build! It weighs just a shy under 25g, and is a quick beast! I was having some issues with the receiver at first, but upon reading the forums; bigger batteries with higher C ratings must be used instead of regular whoop batteries. I was a little disappointed at first, but after my first problem-free flight with the 450mah batteries, I was sold. I am currently waiting for a different camera and canopy to put on to finalize its aesthetics, but for now this will do just fine.
NOTE: This build is a power guzzler. I'm barely getting 1:30 (sometimes a lot less depending on aggressiveness) when I fly indoors at 60-75% throttle with a 450mah battery, and almost no luck with 260mah. The next chance I get I would probably go with a 15,000kv motor and hope to get at least 2:00 comfortably. The voltage sag creates telemetry/receiver issues and it starts to have trouble.

Update: currently using a clear BetaFPV canopy, the Tiny Whoop FX900TW camera, and downgraded the motors to 15000kv (flies much longer now but could be better)!

I see you used the rakon frame but did you buy it from Rakon? They seem to have 2 different frames one says it's for 703 and one says it's for 703 and 603. The link on yours is to rakons site but the sell the 703 at helination. I'm trying to figure out the difference because rakons shipping is crazy slow. Thanks.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
