TRAIANUS 4" Long Range Quad

My first 4-inch, first LR, first dead-cat frame.
I took the smallest M10 GPS and still couldn't fit it well. No idea how to fit the antenna - TBS Unify took all the space leaving almost nothing to fit the mmcx plug-in. It was designed for a 4S battery but tried it with 3S in my room and it was a very stable hover.
Requires GPS test and antenna replacement.

Upd: ordered TRUERC CORE 5.8 (RHCP MMCX90 125MM). GPS is working but heavily suppressed by VTX.

146 grams.
7mins on 3S 450mAh
17mins on 4s 1050mAh (with XT60-XT30 adaptor)

hi, use the bat pad; it's the only sufficient power source for VTX.

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..
