Posted by Steven Shaw on 03/02/2019 21:48:05: Yes some very good people there, also many not so good. Andy Knunz is a Spektrum engineer who is one of the helpful ones **LINK** Thank you Steven. That is a very useful link to add to my armoury.

Steven Shaw - very interesting posts on RC Groups. Thanks for the lead.

Posted by Steven Shaw on 02/02/2019 22:50:30: They've answered this question over on the RC Groups forum Thanks Steven. I am just about to check out the posts on RC Groups.

All points noted Denis. Thank you. I have tried binding both ways and cannot discern any difference! I checked the throttle Safe setting and it is working OK. So throttle is ON and OFF, only as arranged. Thanks again for the thoughts.

Hi again everyone. I have added comments and answers to each of you posts that I had not previously answered. It never ceases to amaze me (although I do not post very often and then, usually with a problem) how the experience of others starts to flow and invariably helps find a solution. Many thanks for your timed help.

Posted by Denis Watkins on 02/02/2019 22:05:29: You have it Steve J Data is also channel 1 If that's the case Gents, how do you connect to transmit data?

Posted by Steve J on 02/02/2019 21:25:10: Peter, Is your AR620 labeled like this? Hi Steve. Yes, that is exactly as per mine. Edited By Steve J on 02/02/2019 21:25:40

Posted by GrahamWh on 02/02/2019 21:09:31: Peter could it be that the Battery port has no signal connection on the PCB - just -ve and +ve, and the ESC of course needs signal connection too? I suppose it could be Graham. All ports have three pins. I haven't checked further.

Posted by Denis Watkins on 02/02/2019 21:00:43: Check channel order AETR? Of the Rx, Is it the same as the Tx or Something else Aileron, Elevator, Throttle, Rudder Hi Denis. Back on the case! Channel order of the Rx is ; Battery: 1= Servo port/DATA ; 2 = Aileron: 3 = Elev 4 = Rudder: 5 = ?: 6 = Flaps

Thanks everyone. Results as follows; Denis - I can confirm that the throttle showed as moving normally and responding to 'throttle hold', as normal. Daniel - I have it in the port next to the Data port - the one shown in the User Guide as Battery port. flyeruk - Ureka! Plugged it into the Data Port and it appears to work perfectly! Why? Why? Why? I have to say that I'm never happy doing things like that, going against manufacturers instruction. If the two of us have had the same problem, there must be others. I wonder if Horizon are aware? Thanks again. Edited By Peter Currey on 02/02/2019 19:21:24 Edited By Peter Currey on 02/02/2019 19:22:02

Thank you Dan and Colin, I have tried that Dan, no effect I'm sorry to say. I do have plane selected Colin. I always do with my gliders as the are they are electric powered for flat-field soaring. Thanks for the suggestions though - I'm willing to try anything. It's not doing my impression of the AR620 much good!

Grateful for any observations. I installed an AR620 Rx in a glider. The Rx binds to my DX8, with no obvious problem. With all channels hooked up, all surface controls work correctly but the throttle function will not operate! I have tried another Rx in line and throttle responds correctly! Am I doing something wrong? Has anyone else had the same problem?

Thank you Piers. The more threads I read and the more pilots I talk to, the louder the message that it's at it's best as a slope soarer! I also realise how much of Lincolnshire is flat! And then you point me in the direction of the 2 videos, one in flat Holland - there's hope for me yet! I will certainly keep you posted as to the eventual outcome.

Thanks Ian, Unusually, for a thread on here, when there was no response within 12 hours, I wondered if I had done the wisest move attaching my query to an old thread?! So I reposted, tonight as a new thread and have had several responses so far. I shall give it another go, trying to choose the best advice then checking and double checking everything before attempting to commit aviation! I shall bear your words of caution in mind. Cheers, PC

Thank you Peter. All grist to the mill. I've started a file of comments and advice. I'm going to take my time and get as accurately set up as I can, before trying it! Just to clarify - mine does not have an all-flying tail. It's just a strip elevator.

Thank you Simon it's helpful to have a recommended start point. I have to say that, although I have flown a number of different RC electric gliders, I've never before had any that tip-stalled in such a frightening and fatal way as the DG1000 I have to admit to being more than a little nervous about the maiden of the re-build!

Massive tip stall Hi Everyone, I had exactly the same happen to my Fly-Fly DG-1000, last year. The damage to the fuselage was so great that I had to get a new one! I have just finished the re-build and it's sitting on the bench waiting to be set up. What movements did you find best, on aileron, elevator and rudder? I can't find recommended throws anywhere! Also, would you expect to use Expo and if so, how much? Thank you in advance for any help you can give. Peter

I'm here Ken. Still breathing!

Thanks folks. The u/c is now modified and awaiting trials. That made the wind speed increase to 'totally unreasonabel' !! It will be a few weeks now before I am able to do any more flying so, keep up the good work of MX2 development and testing. Cheers, Peter

Hi All, I started trying to improve the performance of my MX2 by fitting a 40amp ESC. So far, so good - definite improvement. Now working on sorting out the undercarriage - seems it's the only way to get more than two flights a day, off a grass strip!!!!!!!! Once these two are sorted, will look at the possibility of changing the motor, in line with some of the suggestions in this thread. It still concerns me that, in order to get the sort of performance claimed for any model, I have to spend more and modify it. I'm a Yorkshireman by birth and believe that I should be able to get a minimum performance claimed, from the standard package. Anything beyond that, then I accept it is reasonable to modify at a cost. Does anyone agree, or am I expecting too much

Thanks JayCee. It's enough to make me go and start up one my glow powered models. They are never short of power and do what they are set up to do. Obviously, I expected too much from the MX2.

Hi Alan, Thank you for your constructive reply. I am using Futaba radio, so -ve Expo is good. You are certainly correct about the aileron pushrod exit slots. I just wish I could find a way of livening up the power train combination - ESC, motor, prop. I had expected the ones fitted to be somewhat livelier! I don't really want to have to spend more, changing ESC etc. to make the performance what I think it should have been in the first place. Will keep trying. I have to say that I am pleased to know that it is not just me having the problems. Cheers,   Peter

Hi All, I've just read every comment re the MX2 and I am puzzled. I have one and fly it with four different 2200 Lipos (only one Lipo at once!!). The results are always the same; lacking power, sluggish, short battery life - six minutes at best. The model is as supplied, with a 12X6 prop. although it says on the box that it is fitted with a 12X5 and it says in the manual that the recommended prop is 13X7 !!!!!!!!!!! Apart from the fact that, on the recommended 'sports' settings, it is impossible to get anything like the control surface movements that are stated. Even at half of the throws and with -35% Expo, it is over controlled. I agree witht the comments re the under carriage. It may be OK for tarmac but try it on a field of short grass!! As for prop hanging, you really would have to stand and hold it in the vertical.! So, any suggestions from those of you who are doing all the marvellous things with a standard, un-modified aircraft? I would like to transform it into a competent sports flier. I'm not into the extreme stuff. Thanks in anticipation.

I like the sound of a central under fin. Will see what can be done retrospectively. Had a chat and demo from a flyer at RAF Warbirds meeting at RAF Scampton, yesterday. He does a discus type launch, with motor running!! He holds by the leading edge, just inside the wing-end fin. Not sure I'm that brave!! Will let you know when I've had chance to try again.   Peter
