A fixed wing could probably work but, would require a big flight surface. Perhaps the control system with router, would not have sufficient range to comfortably fly the aircraft without risk of loss...

Re: Sonic Shifter - recent feedback?
Both the WCP DS and the AM sonic shifter are dog-shifting style gearboxes.
An encoder can be fitted to the Sonic shifter out of the box, while a WCP DS does not, but a grayhill or CTRE mag encoder...

Re: WCP vs Vex Ball Shifter
I've checked on the FIRST Choice website 2016 and it's the AMT103-V, I'm not sure about 2015.
The AMT103-V is almost identical in size to the AMT102-V, the problem is that the encoder output pins...

Re: pic: Recycle Rush Re-design Part 2
In long distance power transmission, a transformer is used to increase voltage to crazy high amounts. This reduces the power-loss and means that a less thick wire is required.
Obviously no custom...

Re: pic: Recycle Rush Re-design Part 2
Well the KOP 12awg wire seems to not fit in a 30amp contact.
The other issue is the insulation, the insulation of the sp and SRX wire barely fits into a 45amp connector. I'm not complaining though,...

Re: pic: Recycle Rush Re-design Part 2
That is a very good point, hadn't though about that. That is very interesting to think about.
What 10awg wire did you guys use, and how well does it fit into a 45a powerpole?
