    Thanks Denis - looks like start low & increase by trial & error. I'm thinking FM1 @ 0% ('off switch', FM2 20%, FM3 30% for first flight. Is there any point in any heading hold settings at this stage? I've heard they can potentially be more trouble than they are worth for normal flying. Any ideas on priority settings? I'm using the Spektrum PC programming download for set ups, and unfortunately this has none of the help/explanation/guidance info apparently available on the iPhone or Android phone apps (and the video tutorials all assume you are using these and constantly refer to the help button for detailed guidance).

    Intend installing new AR636 Rx in a scale Lockheed Vega, and wonder if anyone has any advice on typical gain settings for this type of model. There are forum posts elsewhere offering experience with 3D types (quite low settings around 15% on conventional gain) but suggesting much higher values for more sedate sport/scale types - no figures offered. I am guessing 40% - 60% might be OK to start, but would welcome advice on typical figures from anyone who has already got sorted with this system.

    I'm drawing up my next scratch project (Vega 5) and want to make sprung oleos from elliptical section telescopic tubing. I can't find anything ready made, so thought I might 'squash' circular section aluminium or brass tubing to suit. Anyone tried it? Any problems or tips?

    Thanks Dave - I'm sure the Tx will last as long as the airframe, but the long game is to salvage the Rx/motor etc for future scratch project(s). I'm told this is the cost effective way of getting the gear together - although I'm looking forward to plenty of fun with the 'Moth on the way! Pete B - thought so - what a shame! I've just got the Parkzone ultra micro P51 as well - bound to my DX8. Season's Greetings to All

    Bought Ares Tiger Moth 75 (2.4GHz) - anyone know if possible to bind to a Spektrum Tx (Dx8) instead of the crummy little thing provided?

    Nothing wrong with your landings - fast or slow - it's just loss of directional control in the roll-out. A turn develops, then a skid, tipping the aircraft onto a wigtip, which reverses the yaw, wheels alternately 'digging in', hence 'waddle', high CG = nose-over. Increasing rudder area would be a travesty on such a nice scale model, but you could try larger rudder throws, and adding a trickle of power just before the point the ground loop starts to develop. And always land straight into wind! Good Luck. John

    I'm using 6.6v 750mAh Rx batteries. I thought I could recharge on my Graupner Ultramat 14 charger, but it only gives NiMh, LiPo & LiIo options. Online their Ultramat 14 Plus seems to have superceded my model, and does claim to charge LiFe. Anybody know if there is a cheaper way than replacing my existing charger? Are there any inexpensive dedicated LiFe chargers out there?

    I've got some of these, but they come with minimal instructions. I can get it to switch between alarm 'on & 'off', but can't work out how to re-set battery type, threashold voltages etc. Anyone know how? This is the type: http://www.giantcod.co.uk/power-battery-tester-p-406643.html

    Pete/Frank - I've ordered some LiFe Rx packs - I'll let you know if it does the trick. Frank - I already have some of these monitors - thought they'd be useful because wiring telemetry out to the necelles might be tricky - and yes, I could use it on Rx instead, if I had a spare TM1000 (the one I have is installed in another airframe, don't like to keep swapping over).   (I've started another thread on programming these monitor/alarms - perhaps you can help there!)
  18. John Dimond
    Wow! - thanks for that Pete - although I'll need to read it through a few times if it's going to sink in! I have already resolved to power my Rx from a dedicated battery (probably 6.6v 700mA LiFe) I'll make it switchable for convenience/safety, and I shouldn't need to recharge during a flying session (it should long outlast my collection of flight pack LiPos on any given day), but wiil have a spare charged & ready anyway, just in case. The possibility of having the BEC(s) remain 'live' to 'take over' as back-up is particularly appealing - I'll do it if I can.
  19. John Dimond
    Thanks chaps - I've removed the ESC/BEC & replaced with a 4 cell 4.5v Rx pack, and all seems to work OK - I can see the Rx light remains constant throughout repeated cycles (previously it would go out for a moment then back on again when one or more gear legs failed to cycle properly). Conclusion - I think you're right - I need a seperate Rx battery on board. All I need now is to work out how to hitch it up - preferably with externally accessible switch. I'm sure I've seen some info on another thread - I'll get searching..............

    Thanks Frank - previous owner had ailerons on Y lead - I prefer seperate channels for differential etc. I'll try reinstating old set-up to see if it makes a difference - although I feel the DX8 should be able to cope with 2 x Ail set-up. Spektrum are aware of problem - I'm amazed they haven't sorted a fix by now (I don't think they've even raised a service bulletin on the subject - I only stumbled upon 'work round' from another forum post). I've flown the DX8/AR8000 with 2 x ail set-up in two other models (fixed gear) with no problem, so still suspect it'sa something to do with the retracts.   I was running off a 3S LiPo via one ESC - still giving 11.0v+ after problems occurred.

    I have a Deuces Wild with E-flite 60/120 trike retracts. As discovered elsewhere on Forum, with a DX8 set up with 'wingtype 2xAil/1x flap', the flaps don't work unless plugged into GEAR on Rx, and with gear into an AUX port. With this set up, things appear to work fine at first - but on repeated test of gear I got intermittent unsynchronised gear cycles and uncommanded servo movements. Horizon have had the DX8 Tx, AR8000 & retracts back for checks, but returned (after about a month) with 'no fault found'. I have very carefully re-assembled the whole set-up - gear first, worked fine, every time. Then I progressively plugged in remainder of servos, and all seemed to work normally. Just when I thought I'd cracked it, and for no apparent reason, the gear started to cycle out of synch' , and various control surface servos started to twitch again. The attached video clip shows problem before it went back to Horizon, but the performance now remains very similar.   Has anyone else seen this problem - ANY IDEAS PLEASE????!!!! http://www.youtube.com/watch?v=uQHJ9NugLcE
  22. John Dimond
    Glad to hear you've got it sorted Tim - wishing you happy landings! Yes, the Deuces Wild is electric, 1x3S + ESC/BEC each side, plugged into 'throttle' port via 'Y' lead - although I've been testing it with just 1x3S connected one side only. There is no seperate battery for the retracts - reading some other threads perhaps it would help if there was - if I could work out how to rig it up. Having trike gear, there must be a big demand on power with 3 powerful servos trying to operate at once. Anyone think this might help?
  23. John Dimond
    Tim - I'm having similar problems with a set of E-flite 60-120 retracts fitted into a 'Deuces Wild' twin. I'm using a DX8 Tx / AR8000 Rx. The main flying control servos, incl flaps& nosegear steering servo all work fine, but the gear operation is erratic - random sequencing of 1 or 2 legs only at times, and occassionally ALL servos cycle through uncommanded max deflections and have even locked at max travels when only the gear switch was operated. I downloaded the Tx settings to Horizon Hobby who tested it and apparently all worked perfectly. The gear always cycles correctly and in unison when checked on a servo tester. There is obviously some kind of interference/feedback when selecting gear from the Tx, but I'm at a loss as to why they often fail to retract/extend in unison. Any ideas anyone?
