In my robot, i have 4 motors each with a ESC which all have a BEC. These ESCs run into y leads then into 2 channels in the receiver. The problem i think i have is that if all the BEC circuits in the ESCs are feeding the power into the receiver, is the receiver running at 20-odd volts and therefore making the ESCs a little hyper when it comes to slow movements being transmitted to the 'bot?!
also, just ordered a spectrum DX5e system. it does have a built in mixer doesn't it? in the past ive had a v-tail mixer whereas in the manual for the spektrum, the transmitter has a delta-wing mixer, are they the same?
MY DX5e doesn't have a mixer so you would need a V-tail mixer unless your your speed controller has a built in mixer.
I've got a mixer but the issue might be that the voltage it's getting is too high as something in the system isn't working at the moment. Gonna do some more testing to isolate the problem!
You would know pretty quick if you put 20volts through a receiver, the smoke would be rather evident. Unless you have managed to change the wiring then your BECs will be wired up in parallel, ie all positive lines connected together and all negative ones connected together. This means the voltage the receiver sees is the same but there is more current available. Check out some basic circuit theory on google (parallel and series circuits).
The power to the receiver doesn't affect the response of the speed controllers. It is the signal line (the white one) that comes out of the speed controller. Look on google at servo control (pulse width modulation) and you'll learn how the receiver communicates with the speed controller.
What speed controllers are you using?
sounds a little silly but the blue ones from ebay! been testing it and the issue is the mixer (all works without so its either the mixer doesnt work properly or the radio and mixer dont mix) , the radio gear is sadly fine but im using a GWS mixer and they are pretty good quality. looks like ill have to invest in a DX6i so i can do the mixing in the transmitter!
in my experience v tail mixers also stop the robot from fail safeing so be careful with that.
i think we've established v-tail mixers dont work then! lol. is programming a dx6i fairly straight forward?
they do work, never had a problem with them before i got a decent futaba set. I'd recommend getting a decent spektrum though.
they hard to program? ive cancelled an order for the DX5e as there are problems when running the built-in mixer apparently where full-ahead forwards or backwards only gives 50%. The DX6i apparently allows full mixing. will probably go for a gyro as well at some point
