Hi guys,i am looking at building a boomcopter and have a question,is it possible to have 2 throttles on an Hitec aurora,,maybe a second throttle on one of the ratchet sliders on the side of TX,,i know that i can put a motors esc on a separate channel on RX and select a switch on TX and have full throttle or throttle off,,its the cold time of the year in UK and i am bored so decided to have a go at this,,,thanks chaps

You can use a mixer. A mixer is designed much like an aileron/elevator. The throttle Rx is hooked up to the elevator designation. The 2 leads come out of the mixer and go to each of the esc/motors. It is like an split elevator. Change the throttle and BOTH motors change together. So both are synced at all times.

Now the second lead allows equal change to the motors so, for instance you change 50 rpms, the one motor adds 50 and the other motor subtracts the 50. This is done by the mixer electronically. I usually hook the second input lead to rudder for differential thrust, but you could use a another channel and mix it with the slider. I use GWS mixer and it cost about $13.
I like to design and fly unique planes.
