Bumper Whoop

My very first build. Finished! Now if I know how to fly it...

I wanted something I could fly indoors 80% of the times and still have the juice for the other 20% outdoors.

Tips for the next person:
1) Use solder paste! I spent three days trying to get no-lead solder to stick to silver coated wires. Also, it's impossible to find rubbing alchold in Japan. Solder paste cleaned up the flux and got everything to play nice.

2) The adhesive used to glue the carbon fiber to the foam takes about 5 days to dry. During that time it will pick up any dirt, lint, solder bits, dreams, wishes, souls, etc. While it was semi-sticky, I used tweezers and picked at it till clumps would peel off.

The canopy is a RKH tiny whoop top. Running ibus , dshot and a led strip, so had to remap some pins. Batteries are rotorx 3s and turnigy bolt 2s.

Had a complete blast building the frame and can't wait to fly it.

Hey there, great build!

I've got a question: Is there a smaller version of this frame that could work with 6mm brushed motors?

furiouspug Aug 14, 2017

Not that I have seen. I wish they would do a V2 of this frame, maybe thinner or quieter.

SoupOS Aug 14, 2017

yeah that would be nice. I have 2 whoops on standard frames and am looking for some new and exciting frames to test out

whoop style looks lovely! mine ended up like this because i wanted this as flat as possible. (props are dual blades now)
one of my favorite quad now, I can fly this literally anywhere. party time is the best...
seems like you put wraith32 mini like me, (pretty much overkill for this quad though) try bidirectional setup!
when you can flip back from turtle crash, this thing is almost immortal.

You fit a micro in there! Haha
I think the bumper was the perfect frame to start a scratch build on, just so many different configurations and plenty durable.

I am considering moving to smaller motors and esc to cut weight and noise.

Thumbs up for the paste or the candy? XD Just curious, is rubbing alcohol hard to get because of Japanese law? I really like the build tho

I still haven't found any. I read online that some places do carry it. For now, Paste has removed any need for cleaning :)

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..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

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..
