Two Men, One Quad
Before you ask, this has nothing to do with two girls nor a cup…
A few weeks ago PropNuts launched the first in its ‘Will It Fly?’ series where we test out whacky ideas which have been puzzling us. This week we have a new challenge for technology and pilot ‘skill’!
Two Men, One Quad… Will it fly?
We had the whacky idea that perhaps we could invent a new ‘team’ flying FPV race. What if we have two pilots (or potentially more…) trying to fly and race one quad!? Silly idea? We thought so and we decided to test it out.
The idea is that this would test not technology but instead the ability for two pilots to act as one. Can one pilot control the throttle and pitch where another is controlling roll and yaw? More so, can one pilot anticipate the inputs of another pilot before he even makes it?
Will it fly?
Watch and find out.
How did we do it?
Simples. We used a Midge RS210 3mm Carbon Frame designed and built in the UK by Kooltoyz. The frame is perfect with plenty of space to house the receivers and also robust enough to put up with some punishment!
We loaded the frame out with EMax RS2205 2300kV red bottom motors to pack the punch, paired with 2x 20A LittleBee and 2x30A LittleBee ESCs. Yes we have mismatched ESCs.. Why? Because we had them laying around and wondered if it would make any difference at all, in fact it flew without a hitch and no one even noticed.
A EMax Skyline 32 flight controller was used as the brains (basically a Naze 32) and finally we whacked two receivers in to the frame. In order to run two RXs we simply run PWM input into the flight controller, split the channels across the two RXs and also added an additional lead for 5v power supply to the second RX (in fact we made provisions to have up to 4 RXs in the one Quad.. more on that to come.).
Once built, we wired up the correct channels to the desired receivers/transmitters, ensured we calibrated them in Betaflight Config for failsafe and all other functions before its maiden. Finally we closed the Midge up and took it out for a spin.
How hard was it to fly?
Surprisingly (and maybe to your disappointment) it went surprisingly well, even the maiden flight was a success. It perhaps did even better than some of our traditional single pilot quads for a first flight..
The thoughts from the team are that its not as hard to fly as you may think, although we had it on an easy mode. One pilot was controlling speed and forward/backward speed (Throttle and Pitch) and the other was on turning (roll and yaw). So it was pretty intuitive even though you were missing half the controls. We tested the other modes and mixing the controls and indeed they were a lot more difficult!
The real challenge is coordination and communication with the other pilot. We were flying an open field, this is easy.
We have some more plans for the Siamese quad so watch this space. This is only Level One in the difficulty scale, we’re going to mix it up a bit more.
