Any recommendations regarding what you use to print on or write on to display the CAA Operator ID and how you stick the label to your models to avoid them coming off?

Just been reading in the Nov 2019 edition of RCM&E on page 114 about the ZOHD Kopilot Lite Flight Controller. Given that I am a very infrequent flier these days, I wondered if this type of product would assist me to fly with a bit more confidence in less than perfect weather conditions. Has anyone any advice on using these devices, such as ease of setting up, do they work, are they value for money. Are they relatively easy to connect with Rxs and Txs? I use a Spektrum DX6 Tx and Spektrum Rxs. Would this particular flight controller be compatible? I would appreciate any help and advice you could provide before deciding whether or not to go ahead. TIA and kind regards Ken

Hi John, Were you able to get to the bottom of the C of G issue that you raised in your post? I have the same model and am at the point of checking the C of G and also find it most unusual to measure at the wing tip.

Thanks John. So what you're saying is that the Curve number simply reflects the switch that's been allocated to the particular channel? As I said earlier, its a pity Spektrum don't fully explain this in the manual. Regards, Ken 3

Thanks for your explanation John. I'll press on now and sort it out based on what you've said. I cannot understand why Spektrum don't provide a clear explanation of these settings in.the manual. There's no reference to this feature at all. Thanks again, Ken

Thanks for your reply Denis. The Tx is a DX6 NOT a DX6i. I'm familiar with dual rates and expo and how it's used on Tx. I'm looking for clarity on the DX6 screen to set Dual Rates and Expo and in particular the Curve option. Hopefully someone can enlighten me regarding it's purpose and use. Ken

Could anyone give me some help on the D/R & Expo Setting screen please. One of the items on this screen is Curve: plus a number. What exactly is the purpose of this? The manual doesn't mention Curve as far as I can see. Thanks in advance, Ken

John, Where are the Dubro Glow starters available from and how much do they cost? Ken

I have a glow plug starter that will NOT stay connected to the glow plug if the engine is inverted or mounted to the side. It always falls off as soon as I use the starter on the engine and is very frustatiing. Does anyone have any particular glow starters or other devices which will overcome this and will stay fixed no matter what angle the engine is mounted at? Thanks, Ken

Steve, Regarding your suggestion about using a 7mm segment voltage meter on my model - how would this be connected to the Rx given that all the sockets are in use on the Spektrum AR610 Rx? Ken

First of all let me say a big THANK YOU to all of the above RCM&E Forum members for giving me their thoughts and possible solutions to the problems that I described at the top. Today, I took the model and Tx to Martin at Whitchurch Models (Martin is the owner by the way) at his very kind offer and suggestion after spending a lot of time getting nowhere at home trying all sorts of combinations and connections both on the model and DX6. To cut a long story short, Martin, using a process of elimination, finally tried a brand new Overlander 6v Rx battery on the Me 108 which immediately cured the problems I had been experiencing. I wasn't able to do this at home because I didn't have a new battery and I was reluctant to start replacing servos, switches etc etc spending a lot of cash until I was sure what the problem was. Martin was able to do this in his shop and I am eternally grateful for his help and expertise. Whilst in Whitchurch Models, a customer who had been watching and listening to the diagnosis revealed that he changes all his Rx batteries for new ones at the start of every flying season. Some may say that that approach may be a little OTT and extreme but he certainly doesn't get any RX power issues/glitches and there may be a moral in the story there for some of us. Anyway, I can now concentrate on getting the model back together again (with new batteries) and reinstating all the various settings on the DX6 that I'd been messing around with!! Best regards, Ken

The AIL and Flap servos are Supertec S03 and the RUD, THR and ELE are Futaba FP-S148.

They're both 5 cell NiMH batteries and are a couple of years old. I've disconnected the arms from the servo horns on the two flaps and the two ailerons to ensure there isn't any binding on the linkages which may have caused a servo overload. This has made no difference to the servo operation on all of them. When I have the THR, RUDD, ELEV all the time and then connect the two AIL leads into the Y lead to the Rx, all function OK. Then when I plug ONE flap lead into the Y lead from the Rx, everything still works OK. When I plug the second flap lead into the Y lead that's when the ELEV, FLAP and AIL start misbehaving. Conversely, if as above, after plugging in the THR, RUDD, ELEV and then connect the two Flap leads into the Y lead to the Rx, all function OK. Then when I plug ONE AIL lead into the Y lead from the Rx, everything still works OK. When I plug the second AIL lead into the Y lead that's when the ELEV, FLAPs and AILs again start misbehaving. Hope that helps to explain my dilemma - fly with one flap or one aileron perhaps?!? By the way I don't have a voltmeter to check what's happening as you suggest. Kind regards, Ken

Hi Steve, I have two Tornado batteries in the model (separate one for the retracts) and both are Tornado 2000 and both are reading 6.8v 99% full on my battery capacity checker. Ken

Hi All, First of all let me describe the servo setup of the Me108.... 2 Elev servos 1 Rudd servo ! Thro servo 2 Ail servos 2 Flap servos 1 Retract servo I have the 2 Elev servos with Y leads to the Rx, the 2 flap servos with Y leads to the Rx and the 2 Ail servos with Y leads to the Rx. On the DX6, in Aircraft Type in System Setup I have set it as Wing: 1 Ail, ! Flap, Tail Normal. If I don't have the Ail or Flap plugged into the Rx, the Throttle, Rudd, Elev and Retract all function correctly. If I then plug one ail lead into the Y lead, that functions ok, as does one flap similarly at he same time. As soon as I plug the second Ail lead and/or Flap lead into the Y leads, the servos have a mind of their own and the elev doesn't work properly either. They all start flapping about and the orange light on the Rx starts flashing too. I had this model previously setup on a Futaba T6EXP Tx and a Futaba R136F Rx and all worked without any problems at all. I bought the DX6 in order to gradually move my models onto 2.4ghz and take advantage of the model capacity of the DX6. Has anyone any ideas as to what could be causing the issues I'm experiencing. I have tried various different settings in the Aircraft Type without any success. I have now come to a dead-end and don't know what to try next, other than return the model to Futaba radio which defeats what I set out to do. If you are able to throw any light on my problem I would really appreciate it. Kind regards, Ken
