Caviate, I live in France. Am I missing something..
Down my local recycling centre is a steel bin for batteries. Any battery. I asked the bloke, if it was Ok to dump a 5s 4000 in there. It was discharged, wires shorted together. He is God.
“of course” he says, “ but why the trouble to discharge it, we assume they carry charge, that’s why the bin is fireproof.
Because batteryvfires are now a frequent occurrence at recycling centres, hencevwhy we discharge the packs duly, to reduce the energy contained within them that wotlbdvbrvreeasedin a fire. It also reduces the risk of such a fire occurring in the first place because of an internaklshiet which is caused by dendrite growth whichhapoensfaster if the pack is charged.

It’s the salt that makes the current flow.
The salt water method is totally unnecessary snd pollutesvwater with lithium. Just discharge the pack to zero over a suitable load then cut the connector off and twist the ends together, as bperthe BMFaguidance, dispose at the recycling centre.

An alternative to carbon rods is to use metal turnbuckle type rods. That way you can make minor adjustments to eliminate any electronic trimming by adjusting the rod length mechanically very easily. 3 mm rods should be suitable.
On a petrol model like this with a fair bit of vibration going on, I agree adjustable metal clavicles and rods are a good choice - it is not like the weight penalty is likely to matter in a model powered by a 38cc engine.

Good news Matty. 👍
And today I stood up under my own power and can now transfer between bed and chair without the hoist on a natty trolley-like contraption they call the re-turn

Good to hear you’re making good progress Matty. Best wishes for a speedy recovery. Have you suggested climbing Ivinghoe Beacon as suitable physio?
That may.be a tad ambitious for a bit!

Quick update, I am now out of hospital in an amazing rehab centre , and am now doing loads more physio and they have lots of incredible specialist equipment including an exercise bike that has electrodes that you attach to your weaker limb that fire in time with the rotation of the pedddles to encourage your less good limb to relearn it’s role! I am so lucky to get a place here, as sometimes people wait weeks, but I got in last week only about 2 and a bit weeks after my stroke. That is ke, as apparently the early days after a stroke are when you have the best opportunity to improve.

Sorry to hear that news. Wishing you a full recovery! I know too many folk that have had strokes of some form , some younger than you. Colin
I had no idea til it happened to me that it coul happen at such a young age. I am generally pretty fit for my age too…

The worst bit was this happened on Monday, and ir was 45th birthday on the Friday!!!!

Hi everyone- as some of you have no doubt noticed, I’ve not been posting here for the last week or so due to circumstances beyond my control. M starting my rehab now though and will be back as ugmwnted by a 3d printed titanium plate in my head to protect my bran over where the surgeons removed a section of skull to relieve pressure!

Hi Matty. Just gone through all my servos,hitec,corona,futaba, some others,even parkzone and none will fit so it looks like I’ll have to enlarge the holes and make new cover plates!A bit of a pain on a new kit but hay ho if that’s what I have to do I’m going to reinforce most of the fuselage with carbon fibre.many thanks for everybody’s input.Has anyone actually built and flown one of these?how do they fly?
Not personally, I've sen plenty of FlyFly models down the years though. Once suitably reinforced they fly well, so I don't doubt this one will too. Certainly spend some time reading that RCGroups thread @Dickw and I linked above though; there is lots of first hand experience in that thread.

Hi Matty,I’m just going to have a look through my servo box as I have some hitec hs125s wing servos that I’ve had knocking about for some time.Got them for a Pat Teakle a asw17 that I no longer have and they were recommended for that model at the time.Trying to keep the cost down to pensioners rates lol.
I’m not a huge fan of 125s as the geartrains were always a little fragile, but they will be more than man enough for the job torque wise. If you have them already, might as well give em a go.PS - This is the RCGroups monster thread, I’ve linked to a search for “servos” that should hopefully help.

No need for anything special servo wise on a FlyFly IMO - anything that fits should do the job torque wise, the airframes (particularly the tails) tend to be the limiting factor on these.

In the thread about someone buying a new tx - you stated you'd seen a number of crashes caused by Taranis, Flysky and Frsky equipment....
Ah, not at your own club. OK.
Remember, this is practically the only flyer in the country who appears to be in love with the idea of RID, despite the fact the regs as proposed pose a significant risk of his flying site being barred from use. I wouldn't waste your time expecting a fully reasoned rationale from someone who believes an increased volume of unenforceable regulations results in increased compliance...

If ur current radio is a DX9 and you want to move with the times ,, upgrade to a NX 6, 8 or 10 and stick with Spektrum... I recently moved up to the NX8 from my DX7S... NO WAY wud I trust RadioMaster seen to many people have planes and helis pile them self into the ground in a mad attempt to dig their way to Australia.. 2 within the last few months who were flying on Radiomaster.. also over the years seen the same happen with Taranis , Flysky & FrSky transmitters
29 minutes ago, Ron Gray said:It’s always easier to blame the radio gear rather than dumb thumbs.
Indeed. The only common link I've seen between RF "failures" is in the humans in charge of them - those people who actually take the time to understand their kit, read the instructions and install (and power) their setups almost never have problems. Those who don't often have a failure on one brand, bad mouth it to all and sundry, then have a similar issue on their new transmitter. Strange huh... 🧐
PS - OP @David Davis 2, don't forget the added advantage of all the challenger brands like Frsky, Radiomaster Jumper is that RF and RX battery telemetry is built into all the RXs pretty much as standard, so if you have done a poor install or something has gone awry with your power supply, the TX will chirp to let you know automatically.

I'd suggest handling one first, I found it too heavy and due to it's large size and my small hands reaching the switches difficult.
That's just me though as they are very popular at the field.
I take it that is the TX16S you are talking about. I don't disagree that it would be too big for some, but they have other TXs too that are smaller (the TX-12 and Boxer) that all feature the same RF functionality and programming (e.g., way more than any mainstream brand mid-range set), so this is not really an issue any more.

PS- Playing with the variables on eCalc can also be a good way of learning the relationship between prop size/pitch, motor Kv, cell count, and motor mass. They also have a setup finder tool as well, though not all the services are free...

Talk to George at 4 max he is clued up It’s also worth looking on. the recommended set up section on the same web page
Sorry, but I'm not a fan of the "just ask George" approach. Sure, he is knowledgeable on sizing powertrains, but shouldn't a newcomer really develop some knowledge of how their model is powered and why we size stuff a certain way? Without developing this they will be forever reliant on others and/or are much more likely to have an escape of magic smoke?! Far better to teach the man to fish...
25 minutes ago, Murat Kece 1 said:Hi assuming your plane will be about 5.5lb, Eflite Power 25 870kv or its equivalent 4Max 3547x800kv should be more than enough.
Hmm, suggesting a motor isn't terribly useful either without a prop or cell count recommendation - remember, the OP appear to have no experience of electric flight.
@PeteC, here are some resources that should help you to pick up some of the basics - get a brew on and spend an hour or so leafing through them, then come back with questions and we will try to help:
- Crib sheet on powertrain selection from 4-max
- Another decent article on core concepts and sizing kit (the example at towards the bottom is useful)
- Threads on ESCs. motors and batteries in the beginners e-flight forum:

Apparently its Mr Bean's fault we're not buying electric cars😂
No, the problem is multi faceted, and essentially boils down to :
- The economics don't work for most private buyers (especially since the government have removed all the subsidies now)
- The infrastructure to support EVs isn't increasing fast enough. This is especially true if you have no way of charging it at home off-peak.
- Potential buyers are worried about fire risks and insurance costs since Luton and the recent London bus fires
- The most "affordable" current EVs don't have sufficient range to allay the fears of people for whom it would be their primary vehicle (and I say that as someone who likes the EV driving experience and would like to own one).
Add in the fact that the government has pushed out the date that new petrol and diesel cars can be sold til by 5 years, and it's not that surprising that EV sales have stalled. I suspect UK Gov are going to have to start incentivising again if they want private buyers to start making the jump in more significant numbers...

I don't remember names that well but do recall seeing the SAS Apache on an odd occasion. We were often the only ones up flying though!
Funnily enough, I also have a copy of Dave Hughes' book. Not the well thumbed original one that was my Dad's as he chucked a lot of stuff out when he gave up flying.
Yeah, I'm pretty sure my Dad still has a copy on his bookshelf too, though haven;t seen it for a few decades.

Yeah, those don't have the famous Duralene fuselage (from Bob Martin models in the states) the original did, though. The story of those is quite interesting...

Ditto for me. I've always paid through the BMFA.
Why people should expect to see information on the BMFA Membership site when they pay the CAA beats me. Just check with the CAA if you pay through them. Simples.
You don't even need to check the CAA site - if you paid direct you will have a confirmation in your email of the payment and the valid dates, then you will get reminders direct from them to renew. Far simpler IMO than renewing via BMFA (and also means can take full responsibility at renewal time), but I do understand why the BMFA wanted to offer this, even if it makes the Sec's job a little trickier. Each to their own.

...The fact that it happened to me exactly like Nigel shows it's fundamentaly flawed just like the Horizon system. It's uncannily like the Postmasters situation -the screen altered from correct to incorrect whilst I was logged in. It's obviously not a one off human error. Fortunately our situation is not nearly as bad as the Postmasters.

I’ve had a stroke at age44 last week!
in Why Not Say Hello....
Posted · Edited by MattyB
And in my 6th week of rehabwhtomorrow I’mmoving to another rehab centre t to continue my progress. In the last week I have stood unaided from my several timeschaand taken a few steps outside of the parallel bars with a stick for support! This is where I am off to, in sunny St Neots…
