I've progressed with this configuration but I'm, still a bit confused over channel assignment. I've got AS3X working on switch D and it's on by default then gets reduced in Position 1 and off in position 2. I want to set SAFE up. As its only a 6 Channel Tx and I only have one spare channel does that mean I only get one channel to left for the AS3X gain, SAFE and Panic button or can they 'share' a channel?

It's that for sure. Must have blipped the throttle once with the throttle cut off and not made the connection that it was that that made it work. Many thanks for you help. Lesson learnt. NEVER EVER RTFM!

Actually that does make a lot of sense but the AR630 manual says 'CAUTION: Activate throttle cut to prevent motor operationduring this test'. Maybe that's an error on their part.

I was blipping the throttle all the way open (with throttle cutoff activated) each time I tested it so was sure that wasnt the problem. Wasnt sure what I did differently when it did work though. I did notice that when working it is was very active for ailerons but hardly noticable for pitch/yaw.

Hmm, very strange. Seems to be working now and it's using switch D but in the reverse sense to what i'd expect. So position2 is off, 1 is on mild and 0 is more extreme. Not sure what i did to make it work but at least I have something to work with now! It seems like a very complicated area which is hardly covered at all by the Spektrum documentation.

Switch D operates the channel AX1 all the channels looks like this: THR AIL ELE RUD GER AX1 AX2 There's no mixes or expo, just took a standard Acro and the only change was throttle cut

Thanks Dennis but some chatter from the Servos is exactly what I'm after! I just want to see that it works on the bench before building the model. I tried another channel apart from Aux 1 and that didnt work eiher.

Hi, I wonder if anyone has setup an AR630 for AS3X and could help me please? I go through the first time setup and do the orientation etc and the giros work because I can see them changing on the Gyroscope screen but no servos move after I throttle up and down and move the Rx. It's the channel assignment thats confusing me. In Gain Channle Select I'm assigning 'Aux1: D' as thats the unused channel and I assum Input: D is the switch that will be used. Any help would be greatly appreciated!

Thanks for all the responses. I know I'm a little close to the ESC max but it's actually a modified Lazy Bee and it's going vertically upwards when flat out so it doesnt happen often!

I hadn't really done the maths with my LiPos. I worked out that C Rating is maximum disharge rate and therefore bought the highest that seemed reasonable to buy. Now I'm struggling to get the same so I've done the maths and I think (but want to check) that I can use something with a much lower rating. I tested the brushless/30A ESC/Prop combination and was drawing 27A. The previous LiPos were 2200 3S 60Cs. Given the 27A max current draw I wouldnt actually need more than a 20C. Is that correct or am I missing something? I do understand that it's worth getting higher ratings for future models but I dont think I'll ever need the 60C.

Thanks everyone, some really good suggestions there!

Hi, I'm looking for Xmas present ideas for the kids. I've got a Spektrum NX6. Has anyone found a universal Tx case that fits the DX/NX 6 range of Txs? The spektrum ones are a bit expensive. Not sure about dimensions because of the handle on the back.

Thanks for all the advice. Certainly not 'teaching me to suck eggs'! I didnt want to go the SMART route because I already have ESCs and batteries for my aircraft. I'll probably stick with timing flights but will enable the Rx voltage warning for my Lazy Bee as it should be a bit of a floater now it's much lighter with brushless and LiPo. TBH I probably would have gone with the NX6 even if I knew about not getting Flight Pack Voltage as I have the capability to add this in the future when I buy new Rx's.

That makes sense that the Rx will only see the Rx voltage from the ESC - should have though of that! Hmm. Looks like I've spent a lot of money on some kit that doesnt do what I wanted! I dont think the AR410 or indeed the AR630 I bought will give me flight pack volts.

Hi, Ive returned to the hobby and bought myself the new Spektrum NX6 as I couldnt trust my of 35MHz JR set. I went that route because I liked the idea of Telemetry telling me when my battery was low and I should land. Im setting up an AR410 Rx but I cant get the battery voltage over telemetry. I thought (perhaps ignorantly) that the Rx would return the LiPo voltage through the ESC. I have Rx voltage but thats just giving me 4.9V and I know the LiPo is 11 odd Volts.There is Flight Pack Volts but that says 'no data'. Might be worth mentioning that the ESC is connected to the Rx on channel 1. I seem to be missing something fundamental here - can anyone help pls? Edited By Chris King 3 on 21/11/2020 14:09:32

Hi, I'm upgrading my old 35Mz JR set to more modern kit after some spectacular unintentional aerobatics and landing in a tree! I like the idea of telemetry pimarily for battery level and like the Spektrum 6e but I notice that the G3 has voice alerts. Does the e just beep for alerts? Do people find the voice alert useful? I like the fact the G3 is compatible with Realflight too and that alone may swing it.

They were stored in an uninsulated loft so dry but experiencing the full extremes of UK weather!

Thanks for all the responses. Just one last point. Seeing as motor, battery and receiver are being changed is it safe to assume 20 yr old servos are OK if they appear to work OK? They are Hitec HS81s. Dont want to risk all the other kit and airframe just for a few more quid!

Thats great news, thanks!

Hi, I have some (20 yr) old electric models which I've upgraded with brushless/LiPo and want to upgrade my old 35MHz radio with a telemetry set (probably Spektrum 6). I'm aware there are digital servos now. The question I have is will my old servos work with the new receiver?

Thanks for the suggestions everyone. I'm sure there's something here that will work. Chris

IIRC I found thinned down 8" bands were OK with my Lazy Bee (standard size) but it's not been flown for years. Inner tubes are rare these days. We used to use radially cut ones to make bands to hold competition numbers on our trials motor cycles in the 1960s but they'd be much too short (4" ). You could perhaps use small wheel pedal cycle inner tubes cut circumferentially? Geoff Edited By Geoff S on 14/07/2020 20:01:01 Did you chop them in half to get two bands from one?

Posted by Malcolm Fisher on 14/07/2020 19:57:34: For one of my models, I cut long enough strips from inner tubes - single strips not bands and used a hole punch at each end to fit over the dowels. Worked well for me and they lasted longer of I made the ends wider where the holes had to be punched. Malcolm Hmm, that gave me an idea. I took an old band and cut it so it was one run and punched a hole in both ends and its pretty strong. A 4" band nearly goes the distance I need. That might work. It's just judging how strong the end with the hole is.

Posted by Jeffrey Cottrell 2 on 14/07/2020 20:16:30: Hi Chris When you say 22" do you mean the total length around the band, or the length of the band laid flat? If you mean the total length that would mean a chord around the 11" area. Rubber bands are measured folded flat, and unstretched.. I have some bands I use on my Limbo Dancer. These are just over 7" unstretched, but will happily stretch to over 11" in use. Other than that, Amazon do list some 200mm ( 8" ) here. Personally, I think 8" would do you fine. Jeff The chord is about 15". The 22" inch I quoted was the length of the band layed flat. e.g. the length from each dowel diagonally across the wing

Even First Steps only go up to 8" or 200mm! Not sure what size inner tube I'd need tbh. Don't have them around these days as everything is tubeless.
