ultralight runcam split build
planning on mounting the split controller under the frame with a another 30x30 plate underneath it to protect and strap the batteries to

current theoretical dry weight is just under 100g ....all up with 450mah 4s battery will be around 160g!!

RS1106 7500kv + gemfan 3025 on 3s puts 440g at 26amps (bench test)
This makes this thing about 11:1 thrust to weight ratio!

2017-12-20
Completed! 108g + battery. With 450mah 3s she is a sprightly 150g!!

Gearbest sent me a replacement F428 yay!

I've had 3 split builds and all of them froze on me. The runcam split mini v2 I have no froze on me too. However, since I put it on full lipo voltage and common ground with VTX its held up fine. Maybe you are only supplying it 5v which will lead to freezes?

Did you try a different SD card - my Split V2 froze with a cheap SD card, but was fine with a decent one....

Well, the PCB fried when I crashed. Something shorted out and one of the chips let out magic smoke. I've since replaced the PCB and use it in another bird. Yes, the first thing I check is the SD card when I get freezes as well as the power supply.

Any flight footage?

just some garbage tuning footage


After the runcam split froze and took out the FC, ESC and the split controller I never put it back together.

Looks great! I‘m doing the exact same build, but with 2-3s batteries and 4500kv motors, so it won‘t be quite as punchy.

nice! You'll get a lot more runtime... check this guy's out -

Nice! Love the added bottom, great idea. Just built one using the same frame, without the split, and it rocks.

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..
