Wiretap's 2S Lollipop75

By wiretap on Aug 27, 2017

6 3 5

F4 build with 6A 4-in-1 ESC, 0703 motors, and FPV w/ OSD on the Lollipop75 frame. I'm using a 2S 450mAh battery with this.

Unfortunately the camera I chose was a little too large to fit into the chassis, so I mounted it up top with a zip tie. In the future, I'll try to find a smaller AIO camera that supports video in/out for the OSD. I also mounted the flight controller 180-degrees rotation so the 6-pin connector would fit due to being too short to mount it the proper way -- a quick correction that needed to be made in Betaflight.

Here's a video of my first time flying acro mode:

We've talked before, and I am all finished building mine...it's been sitting here because of an issue I can't seem to solve. Since you are the inventor of this build I thought I'd ask you! :) Problem is, when I spin up the motors in Betaflight 3.3.1 the motors don't spin, this just twich back and forth! They never make even one revolution. Everything else seems to work fine. I have flashed to the latest version of BLHeli, but can't seem to figure out why they don't spin up. In the 3.3.1 configuration tab, I have it set to DSHOT600, 4khz/2khz, and have tried different settings to no avail. All the parts are brand new...
Got any ideas?
Thanks for your help!!! :)

Seems like the cam would take a lot of hits! Did you get a smaller AIO? How has this held up?

What kind of batteries and connector do you use? I just ordered the parts.

wiretap Sep 30, 2017

JST RCY connectors. I use 2S 300mAh batteries now which provide a little bit better experience due to the weight reduction.

how much flight time did you get from this setup?

wiretap Sep 30, 2017

A little under 5 minutes.

Nice! Hos do you like that FC. For the camera, you could always desolder the cam from the transmitter and run the video through that way.

The flight controller is great from the first few test flights I've done so far. It does get very warm, but I haven't had any overheating issues. As for the camera, I have a few other cameras on order that I'm going to be test fitting. Desoldering the current camera isn't all that easy since it was epoxy sealed at the connections.
