Sub 250g 3" CheaterKwad

The secret to this 3" CheaterKwad build is the tiny ViFly camera switcher.

GepRC Cygnet 3" front camera cage also fits to the rear (two screws on the bottom and four screws on the top) so to get a second camera cage you will have to buy an extra frame. The good news is that you have a spare top and bottom plate in case you break one.

The motor mounting pattern on the GepRC Cygnet 3" is 9mm x 9mm, unless you buy the Pro Version which is 12mm x 12mm

Dry Weight is :-130g

I used a GNB 550mAh 3s Battery and get about 4 minutes of flight time.

Tip :- Use a shallow angle for both cameras, if you don't you will just film sky when flying backwards (You also have to alter your flying style as you will use more Yaw and less Roll).

This is my first Rotorbuilds project so if you have any questions or want more pictures please just ask.

Is it possible to convert it to a DJI FPV build

Yes there is room to have a stack at the front and put the DJI Air Unit at the Back, Here are a few of my Sub 250g DJI Digital HD FPV Builds :- https://www.youtube.com/watch?v=s18gKTGMAu0&t=1s https://www.youtube.com/watch?v=HxTaRwFuJIw&t=1s https://www.instagram.com/p/B50pY04nJAX/ https://www.youtube.com/watch?v=-PYE6lmB8zE&t=18s

Thanks.

I am definitely looking to build a sub 250 gram, would they be powerful enough to carry a go pro session. I know it will incerase the weight but just wondering.

A Go Pro Session would put you over 250g, I could add a GOPRO to my 4" but it wouldn't fly very well at all. You really need at least a 1408 motor to give you the extra power to carry one and still have your quad fly well.

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..
