JupiterTwo Posted July 30, 2021 Share Posted July 30, 2021 Hello there. Has anyone any experience with Spektrum SX107 micro servos and Futaba Receivers? I picked one of these up the other day for my Ryft build, and when I plugged it in it wouldn't work. I returned it etc, and ordered a new one from a different supplier. That's arrived today, and the same thing, it appears to be DOA. Now that seems unlikely. The reciever (RS304SB-E) is in 'normal' speed mode, so supports analog and digital servos. But nothing happens. I've tried it in the normal steering servo port, but not a peep. I've not found any comments of this combo not working yet, so I wondered if anyone else had faced a similar issue with this servo? Quote Link to comment Share on other sites More sharing options...
JupiterTwo Posted July 30, 2021 Author Share Posted July 30, 2021 Just tried it with an R2106GF receiver. No signs of life either. /sigh Quote Link to comment Share on other sites More sharing options...
JupiterTwo Posted July 31, 2021 Author Share Posted July 31, 2021 Another one arrived today, same situation. That seems very unlikely, but why wouldn’t they work with a simple 2ch futaba receiver? power hd tr4 booked for Monday, so at least the build can continue Quote Link to comment Share on other sites More sharing options...
Kpowell911 Posted July 31, 2021 Share Posted July 31, 2021 What transmitter? Are they binding ok? Quote Link to comment Share on other sites More sharing options...
JupiterTwo Posted July 31, 2021 Author Share Posted July 31, 2021 Futaba 4PLS, 3PKRA or a 10J. It all binds fine, other servos work in their place etc. Quote Link to comment Share on other sites More sharing options...

Yep, savox, power hd and a different spektrum servo all work in r304sb-e, r202gf and a r2106gf Quote Link to comment Share on other sites More sharing options...

Yeah, I've tried them too with the three different futaba receivers I listed. Just got home to find the a different micro servo delivered (PowerHD TR-4), and that's worked straight away. The odds of 3 in a row being borked are not in my favour, but I'll have to return them or get a servo tester. Quote Link to comment Share on other sites More sharing options...

I meant are you able to try them with non futaba receivers to see if the servos are working Quote Link to comment Share on other sites More sharing options...

No worries though, they're in the postal system now back to their suppliers. Waiting on the 25t servo adapter to arrive so I can hook up the TR-4. Thanks for your interest in this one, hopefully it's just my bad luck. 1 Quote Link to comment Share on other sites More sharing options...
