Bob Cotsford Posted December 17, 2019 Share Posted December 17, 2019 I've just taken delivery of two 60A Neuron 'S' escs to be used in an E-Flite Deuces Wild. I've used the original Neurons and found them excellent other than being bulky. The Neuron S changes that in a big way! The original non-S is 59*35*17mm, the S version has shrunk to 44*22*12mm. Believe me, when you see the difference in the flesh it's quite amazing. I'll try to get some pics for comparison later. The S is about a fiver more than the earlier version but the units from T9Hobbysport include a BLHeli32 USB linker with each one, that has to be worth the fiver in itself. Now I just need to work out a wiring harness to drive tricycle electric retracts from one esc and the XPS Sbus decoder, dual receivers and the servos from the other with one three way Ashlock connector between wing and fuselage. I'm sure I have some Veroboard knocking about somewhere! Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted December 17, 2019 Share Posted December 17, 2019 Bob, You beat me ! My 40s was in the mail yesterday but has not arrived yet. It is destined for a trial in a Tony Nijhuis mini Gnat , can’t be many of those with a near full Telemetry suite. I like the Banggood Sbus decoder for complex wing joints .

Chris Bott - Moderator Posted December 17, 2019 Share Posted December 17, 2019 It will be good to see photos, Bob. That sounds like quite a setup you're planning there. It will be interesting to know how you get on with telemetry from two Neurons. You would even have the option of comparing RPMs and doing something if they're too different.

Bob Cotsford Posted December 17, 2019 Share Posted December 17, 2019 I've only used the FrSky 4 channel and XPS 10 channel decoders to date, and after selling off all my IC models I've ended up with two or three XPS units spare so never had cause to try the Chinese versions. Do the Banggood decoders include receiver redundancy like the XPS ones? Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted December 17, 2019 Share Posted December 17, 2019 Bob, Rx redundancy I don’t think so , at least not on the version I have. I used it because it allowed me to use the ‘normal’ frame rate after decoding from the Sbus viz the high frame rate of the FrSKy decoder , hence allowing me to continue with analogue servos .

Ron Gray Posted December 17, 2019 Share Posted December 17, 2019 That's some setup Bob, I've just acquired a Deuces and have set it up so that I have a separate battery for the retracts only, therefore I don't have them connected through the SBus, they bypass the SBus decoder and go direct to the RX. Redundancy RX can be provided using the R series RXs plus say the R-XSR as the slave. What power units have you got on your Deuces? I've upgrade mine to a couple from 4-Max to give me the option of 5s should 4s not give enough of an adrenaline rush! Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted December 17, 2019 Share Posted December 17, 2019 Parcel Force just arrived with mine. I had ordered a Bel Heli usb linker so I could have a proper play and just like Bob’s 80S , FrSky included one with the esc. ah well looks like I will have a spare! Tim Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted December 17, 2019 Share Posted December 17, 2019 Closer inspection of the linker I paid £6 for shows it to have the smaller USB plug you find on the end of some normal USB leads. A spare nonetheless. I note FrSky were good enough to include a link lead with their Freebie. Looking at the manual, I think I am correct in saying it needs the centre power lead isolating before you use it to avoid damaging the ESC, unless perhaps the SBEC jumper is not on ........

Tim Ballinger Posted December 17, 2019 Share Posted December 17, 2019 Thinking too much too soon. I see the S port on the Esc only has 2 pins so lead they supply is fine as it is. Tim Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted December 17, 2019 Share Posted December 17, 2019 Gosh these small diagrams in the manual can be tricky. I thought the usb programming lead went to the sport but I was wrong it is shown connected to the Rx output as would be normal with a programming card. So the power pin/ lead does need removing.

Bob Cotsford Posted December 17, 2019 Share Posted December 17, 2019 Ron, the DW is set up with a pair of Emax BL2826/06 850kv motors which have a 60A burst rating the same as the Power 32 'upgrade' recommended in the manual. With the 12*6 APC-Es fitted it should have about 600-650W a side on 4S. Damn but that wing is heavy! On the other hand, there's no weight in the fuselage. I'll have each u/c leg on it's own channel, each with a delay to stagger start/end current peaks. I've got 10 channels to play with on the decoder, plus it has built in receiver redundancy handling. I could just use an X6R or S6R for the primary and the micro XM as the backup receiver. If I change the ID on one ESC I should get independant telemetry from each, that's left/right motor consumption, pack volts, motor currents, BEC currents, esc temperatures - this could make setting up warnings and widgets complicated! Makes the power wiring seem simple. Tim, it's odd FrSky supply an update setup with all three leads, maybe they enjoy warranty claims? I had to go and check my linker to remind myself how I'd done it before and sure enough, I had disconnected the +ve lead.

Bob Cotsford Posted December 17, 2019 Share Posted December 17, 2019 'Standard' Neuron (black), Neuron S (red) and the Mystery brand (yellow) esc that came in the model. The Mystery is a pretty standard sized 60A unit and gives an idea how much they've slimmed down the 'S' version. OK, the Neuron is an 80A one but the 40 and 60A ones are the same size!

Tim Ballinger Posted December 17, 2019 Share Posted December 17, 2019 And now the Neuron 40s is even smaller than the 60s and notwithstanding the Telemetry sensors is smaller than any other ESC with same rated SBEC I can find. Tim Quote Link to comment Share on other sites More sharing options...

Makes the power wiring seem simple. ... Of course last night I realised that this was written in a senior moment as it can't be done with two Neurons as they don't have daisy-chain connections. They can only be used to terminate the Sport chain - bum! edit - When Sport first appeared the documentation stated that sensors should be daisychained, but delving into the web there are indications that the daisychain connections on sensors are just connected together, effectively putting sensors in parallel. I'd never really thought about it before, perhaps there is hope after all? Edited By Bob Cotsford on 18/12/2019 13:00:30 Quote Link to comment Share on other sites More sharing options...
Chris Bott - Moderator Posted December 18, 2019 Share Posted December 18, 2019 Bob yes the two connectors are paralleled. Just use a Y lead. Chris. Quote Link to comment Share on other sites More sharing options...
Geoff S Posted December 18, 2019 Share Posted December 18, 2019 To add to my Horus update woes (now cured - I think) my Neuron was dead when I tried it yesterday. No BEC voltage so the receiver didn't work. I tried powering my recever separately (after disconnecting the middle pin on the connector) but still no joy and it was getting slightly warm. Contacted T9 and I posted it back this morning, hopefully for a replacement under guarantee. Geoff Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted December 18, 2019 Share Posted December 18, 2019 The Neuron that I cooked is on it's way back from T9 but Richard didn't know whether FrSky repaired or replaced it, either way it's a Chinese warranty that is respected. Thanks for confirming that Chris. Geoff, this will be where Companion pays dividends as I can copy an existing model using a Neuron (Ultra Stick for example) and cut/paste all the logical switches and special functions to duplicate them, editing the references to point to the second motor's esc. Much easier than doing it on the transmitter! Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted December 18, 2019 Share Posted December 18, 2019 Frustrating for you Geoff, just when you think you are back on track. I put the connectors on the 40s this morning. I have not experimented withe Bel Heli interface yet as I need to read up a bit first. However when connected up everything worked. The luac script on the Tx seems to work and reports back with all the fields filled in although I have not tried altering the SBEC voltage yet. All of the Esc parameters reported back as expected and the EscR lets you set the number of motor poles ( it defaults to 1!). Currently I do not know how many poles the FMS fan is but 7 looked reasonable as a guess. What did not show up were the two BEC parameters ie voltage and current. Got Rx voltage as normal but not the actual BecV or BecA as advertised. Since I had to take no action to get the Esc parameters I am wandering if the BEC parameters have not yet been enabled for the Horus OS. Might have a look at the Freelink output and see if they are on the dashboard. Be interesting to see if you Open TX folks get the full suite.

Bob Cotsford Posted December 18, 2019 Share Posted December 18, 2019 I think they should show up on OpenTX 2.3.1 onwards, I'm not so sure about FROS though. Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted December 18, 2019 Share Posted December 18, 2019 I have not loaded the latest Beta to FrOS as the notes did not mention any further Esc parameter updates. Might have another look and check. Slightly nervous of beta updates so I will probably wait for the next release. Freelink was next to useless. Had markers for ESC an SBEC parameters but did not read them. Tim Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted December 18, 2019 Share Posted December 18, 2019 Just checked and FrOS went to latest version on 11 December. No mention of any further Neuron updates though. I’ll wait till you report back on the OpenTx monitoring. Tim Quote Link to comment Share on other sites More sharing options...
Chris Bott - Moderator Posted December 18, 2019 Share Posted December 18, 2019 These are my Neuron telemetry points. That's the ones all numbered 240. 249 are separately monitored LiFe flight battery and UBEC volts at the point that these are fed to Rx via diodes.

Tim Ballinger Posted December 18, 2019 Share Posted December 18, 2019 Thanks Chris, I have everything except the BEC Amps and Volts. Is that list from the ‘old’ neuron or the new neuron S? Tim Quote Link to comment Share on other sites More sharing options...
Chris Bott - Moderator Posted December 18, 2019 Share Posted December 18, 2019 Tim that's from an old/full size Neuron 80. Quote Link to comment Share on other sites More sharing options...
