SONNY MONKS Posted November 14, 2018 Share Posted November 14, 2018 If you have enough channels,would you choose two seperate channels,or one,with a y lead? Quote Link to comment Share on other sites More sharing options...
PatMc Posted November 14, 2018 Share Posted November 14, 2018 Seperate. Quote Link to comment Share on other sites More sharing options...
Frank Skilbeck Posted November 14, 2018 Share Posted November 14, 2018 Separate, that way you can easily adjust the amount of aileron differential at the Tx. Quote Link to comment Share on other sites More sharing options...
Don Fry Posted November 14, 2018 Share Posted November 14, 2018 Ditto, it allows fine tuning via the transmitter, makes differential easier, allows flaperons. No downside, except, two plugs to attach, instead of one. Quote Link to comment Share on other sites More sharing options...
SONNY MONKS Posted November 14, 2018 Author Share Posted November 14, 2018 Thanks frank,ive changed it to seperate on my frsky X6R,i was quite surprised when i plugged the second servo into channel 5,and it was already operational,i thought you had to mix it,from channel 1 of course,certainly made my job easier,i thought it would be a right job,with it been frsky,as im still getting to grips with it.

Nigel R Posted November 14, 2018 Share Posted November 14, 2018 Separate, because you can do subtrim and differential with ease. Although differential also easily possible by using a slightly offset horn. If I only had a Y lead I wouldn't worry too much, though.

cymaz Posted November 14, 2018 Share Posted November 14, 2018 Separate aileron servos and channels. And if you can separate servos and channels on the elevators. Quote Link to comment Share on other sites More sharing options...
Dave Hess Posted November 15, 2018 Share Posted November 15, 2018 I had an interesting situation the other day. The BEC on the cheap ESC wouldn't work with two servos on one channel, noteven 3.7g ones, but it was fine running two 9gservos at the same time on separate channels. Naturally, I changed itfor one that could manage it. Quote Link to comment Share on other sites More sharing options...

Naturally, I changed itfor one that could manage it. When you say the BEC wouldn't work do you mean the servos wouldn't operate. One "feature" of modern 2.4 systems is that the position voltage/current is quite low and if the servo requires a strong position signal and they don't like sharing it on a Y Lead. Note this is not the power to run the servo motor but the signal which tells the servo where to go, this signal comes out of the decoder chip in the receiver and is very low power so wouldn't cause any issues with the power feed to the Rx. Although we did have an issue one time with a servo that worked fine on a Rx battery but overloaded the ESC BEC, in this instance it was a faulty servo that was overloading the BEC.

Gary Manuel Posted November 15, 2018 Share Posted November 15, 2018 This really is a "no-brainer" Sonny. If you have the channels - use them. Edited By Gary Manuel on 15/11/2018 16:15:05 Quote Link to comment Share on other sites More sharing options...

What happened was that everything was OK when i switched on, then I started wiggling the sticks to test all the servos. Everything was OK for about 6 seconds, then the ailerons went nuts and ended up stuck with the arms gone past 90 deg movement. Once that started, the elevator and rudder were no longer controllable. I tried two pairs of servos, which both behaved the same, so i swapped the ESC for a better one and everything was OK. I had a similar experience before, when I knackered a good quality ESC by connecting it the wrong way for a short time. Fearing I had done it again, at first ,I tried a second ESC that was the same type as the first, but the servos behaved the same. What do you think? it's one of those £4.50 Orange DSMX receivers.

ChrisB Posted November 15, 2018 Share Posted November 15, 2018 Either or. Y leads can attract RF interference on occasions but it's always pot luck. Quote Link to comment Share on other sites More sharing options...

Nigel R Posted November 19, 2018 Share Posted November 19, 2018 I gotta watch you guys! For the record, I found on Hobbyking: The cheapest Orange [410] with DSMX and actual servo plugs is £9, 6 channel version is nearly £10. A CPPM plug version is £5.50, but that's intended for quads I think. The older DSM2 only 6 channel receiver is £4.70, maybe Dave means that one. But that isn't DSMX.
