I would like to thank you all for your answers, they were very helpful. I own a few power supplies (leftover of a previous activity) and, since I am just a beginner, I would probably choose a small DC charger such as the ISDT Nano. At the field we have AC outlets, I could bring one of my bulky power supplies with me and the small DC charger or possibly buy another small AC charger. As an alternative to Overlander (very good), is the SkyRC line good?

I understand now. Thought "parallel charging" could denote charging two packs concurrently attached to different charger outputs. It's a physical (electrical) parallel instead.

I have to confess I'm a little bit confused, probably because I haven't read the guidelines for safe charging (yet) and I am not familiar with balanced charging. Why can't we monitor the individual cell voltages of every cell being charged when we charge in parallel? Some of the parallel charging units which have been recommended here (thanks to all, it's been really helpful!) have large touch displays, why shouldn't they display separate data for the, say, two batteries being charged in parallel?

Hello, I am looking for a charger (last component before my first flight). Two are available at my location (not considering high-end models): Accucell s60 and iSDT D1. I have to say that instinctively I much prefer the latter, which however costs twice as much. What would you recommend? I would like to use the charger for my electric glider (2200mAh 3S) and, if that's possible. for any other small rechargeable battery at home (have no proper charger, only awful cheap AA/AAA small chargers).

Thanks Ken. Will Turnigy 25C be enough given that the recommendation was 20C? I've read somewhere here that C-rates must be taken with a grain of salt, due to different measurement practices at the manufacturers.

I am looking for a 3S2200 battery for a new Easyglider 4. The connector is MPX. Multiplex recommends its 20C Roxxy Evo and I am wondering if an alternative could also work, besides being cheaper. Say, a HK Turnigy 25C, 30C or 40C. In that case, I would also need a XT60 (or other connector) to MPX adapter. What would you recommend, the more expensive Roxxy or a Turnigy (which discharge?) with adapter?

The Multiplex Cockpit SX9 is among the ones I like the most. I would like to ask you three questions. 1. Would you recommend it to a beginner? 2. Being familiar with computer programming, I considered buying an Open-TX based transmitter, because apparently they have a higher performance/price ratio. Should I realise that I don't like RC flying after all, I would probably waste less money. I have two concerns, though. The first is that to fully exploit their potential, I fear I should spend a significant number of hours programming, and I would rather spend more time learning to fly than sitting at a keyboard. The second one is about the possibility that some kind of malfunction might occur in flight due to wrong patches, or wrong modifications by me. That said, the question is, again, would you recommend such devices to a beginner? 3. Finally, how good an investment is a Multiplex transmitter now, in terms of support and value over time? Multiplex make excellent kit (I used their TXs for 15+ years), but I couldn't recommend a beginner starts with them at this point. This is because I don't have complete confidence they will l continue in the market in the long term. Yes the M-Link protocol itself and receivers are now likely to be made in the long term given the emergence of the top end megabucks M-Link Powerbox Core, but will there ever be another Mpx branded TX for the rest of us? The Profi was a flop and with seemingly no intention to distribute in the US it seems doubtful there is enough space in the market for them; Frsky and other OpenTX transmitters are eating their share in the low/mid range and Jeti pushed the disappointing Profi out of existence at the top. Re: OpenTX, given your background you are unlikely to have issues, particularly if you have used object oriented programming languages in the past. The people who struggle with it tend to be those who come from a none object oriented "canned mixer" system like JR, Futaba or Spektrum - it's much harder to "unlearn" one of those approaches than it is to start from fresh as you will be doing. Yes it has huge functionality and can be very complex if you want it to be, but equally you can setup simple models with the wizard in a few mins too. Despite what you may read thee is actually no real need to update OpenTX unless you really want the very lates bleeding edge functions - I went years before I updated mine. You just need to understand the basic flow, start with simple models and you'll very soon have all the understanding you need. This video may help... PS - OpenTX was actually inspired by and takes most of it's concepts from Multiplex OS's from the 90s, so you are actually choosing between two systems with a very similar approach, though any OpenTX set has a lot more functionality layered on top than a current Cockpit.

Posted by Frank Skilbeck on 02/10/2020 08:04:35: Stefano, I am a long time MPX user (Cockpit Sx 35 MHz, Royal Pro and Profi), friend has a Cockpit Sx9, it is very easy to program and I have never need to refer to the manual or you tube videos and it's very easy to make adjustments at the field. The telemetry functions are very easy to use too. But receivers are expensive and there are no cheap compatibles around. A few of my friends also use Frsky with Open Tx, and these work great too. The only issue some of them have is that they find it takes more time to program and also don't like making any adjustments to the programming at the field so usually go home to make any changes. Ironically being a Royal Pro/Profi user I can sometimes help, but do admit that some of the Open Tx menus are not intuitive. I do agree with Geoff, I'd never put a 7ch DR rx in a Lidl glider but I would happily use one of the 5ch lights which are quite a reasonable price. But if you are just dipping a toe in the water then have a look at what your local club uses, that way you'll not only get help with setup etc but possibility of buddy boxing, which a much less expensive way of learning to pilot a RC flight. That is a very good idea. I know that one of nearest fields has a school and it's using Jumper TXs. But I ignore what the trend is here among pilots.

I have a Cockpit SX9 and I bought it a couple of years ago when I got back into the hobby. It has performed faultlessly, has all the features I am ever likely to want. I fly full house gliders, sport aerobatic and funfly planes. It is very easy to programme and takes next to no time to set up a new model. However, the receivers are quite expensive and the supply is variable at the moment so I would check this out before you commit. Only MPX rx's can be used with it. Because of this, I didn't want to put £35 + receivers into Lidl rc conversions so I bought a secondhand RadioLink AT10 which can use cheaper rx's. At the slope today a chap was flying a Pike all moulded glider and it was being guided superbly by a RadioMaster TX16. The pilot said it was very easy to programme and has a multi-protocol module so could be used with most receivers. It's much cheaper than a Cockpit SX9. It depends what models you will be flying whether it will be worth the expense of MPX receivers. Personally I love my cockpit SX9 and have complete faith in it and wouldn't want to trust my £300 glider to a cheapo receiver but, as I've said, I wouldn't want to put a 7ch DR rx in a Lidl glider. My (very) long term goal is to fly a Freewing P-38 or a EDF plane. Before that I would like to complete the assembly of an old Amigo II. Probably I am being too ambitious and should start with small propeller planes. I haven't really decided yet, also because due to Covid problems I can't get the license very soon.
