Artto have a look at the Powerbox PBS-T250, but you'd need the programming lead to change the operation to Futaba.

David look at it as an opportunity to replace the single aileron servo with one in each wing.........

How about a Mini Astro Hog, plan available Here

Bit of old school training earlier in the week (yes I know, I've told him to route the exhaust away from the model)

ED if you look at UK power consumption it typically peaks at over 35GW during the day and drops to below 25GW at night for around 6 hrs, so thats 60GWh headroom every night, so around 180,000,000 to 240,000,000 miles of additional range every night above the circa 1.4 million electric vehicles on the road at the moment. But yes more generating capacity is required but it's not as great as many say it will be and it's over the next 15 years, by which time EV car owners will probably be paid to feedback in times of peak demand. But heat pumps will also add a demand too. Needs some joined up thinking from the government, so I do share some of your scepticism. Plenty of negative articles on EVs on the internet.

I prefer to do my maidens when there are clubmates at the field, another pair of eyes never goes amiss, and although not needed yet 🤞additional hands if it all goes wrong 😗

It's a lot simpler than some programmable transmitters 😀

BTW I would not recommend leaving an EV on charge on a standard 13amp socket overnight, they are drawing 10 amps continuous and the socket will get warm, if the socket/ wiring is not in perfect condition then it could catch fire. The standard wallbox has additional protection built in and if installed by a competent electrician will not be connected via your consumer unit but wired up with it's own breaker and protection etc and also monitor the total feed to the house and disconnect the car if the total load reaches the household limit.

Yep, do all the above checks plus a failsafe check, surprising how many models turn up at the field with the failsafe not closing the throttle.

You'll get around 2.2 kw, so every hour that would be around 9 miles range added every hour. When we first got our Mini we charged on a 3 pin plug, one charge took 8 hours to go from 40% to 95%, but the Mini is a small battery.

Just one note of caution, if asked to test a model on a Tx using Open Tx don't only check the control directions but also the that the trims work in the correct sense too.

I like to maiden all my own models, and practise is very similar to Jons. But have some club members who prefer to have somebody else test and trim out their models, even then I've flown something got it flying nicely and on the owners first flight they's either hauled it off the ground too soon or stalled it from 6ft on landing because the model flies different to what they normally fly, so I often do a few take offs and landings for them and let them have the Tx to get the feel for the model. I've got an EDF been waiting for a maiden flight for a couple of months but the weather has stopped me from getting our strip EDF ready.

Yep, IO has yet to charge our Mini in the fixed 2330-0539 cheap time slot, plugged it in last night at 16:55 and got a message that charging was delayed until 17:00, probably to pick up on 30min smart meter time slots, all finished by 19:40. And we would still get the cheap rate on the overnight period. As I noted earlier we are plugging it in around 5pm so we can also cook our evening meal on cheap electric too 👍 I just have a charging schedule set up on the Ohme app to charge the car to 80% by 8am, plug it in and let Octopus decide when they'd like to charge it up with cheap electric, very simple to set up and use. Would be more complicated if you had home storage batteries as you'd want to make sure you charge them in the period and don't draw on them.

Probably, without the crystal it won't be transmitting, with it will so the extra power is drawing the battery voltage down a bit. Not sure why you can't get into programming mode but make sure the gap round the push buttons is clean, it maybe that they are not fully depressing.

👍with the Ohme pro, on the Octopus devices page it takes you to the Ohme app, different presentation but basically the same info. I note you've got it to add 80%, so it will try to add 80% of the batteries capacity, i.e. if when you plug in at 10% it will take it to 90%, if your cars app talked to IO then you could tell it to charge the battery upto 80% regardless of the starting %.

Ron, the idea is you plug in and OI determines the best times to charge to meet your target, sometimes you might be given multiple slots to meet your target.

Or stick some bits of wood on to simulate some dummy cylinders, if you don't fancy cutting them Sarik do this wood pack. But at least paint them black.

Just got an old model with an even older Kalt 22cc mag engine, would only start on a prime, so I serviced the carb, new carb manifold gaskets and away it went, what a lovely engine, standard exhaust is too noisy so will need to be addressed, but at the time I thought why have manufacturers stopped offering magneto engines, they are a great all in one solution. My mates Zenoah 38cc is similar. Good luck with your search.

It's a tricky balance, an opensided structure would help dissipate any hydrocarbon spillages and prevent a vapour cloud, petrol has a flash point of -45 degC, preventing concentrations reaching the flamable limit, so while enclosing it may reduce the severity of a fire, it may increase the probability. Offshore oil/gas production platforms enclosed modules are designed for a certain number of air changes per minute with gas detection sensors to monitor hydrocarbon, with non hazardous modules being at a slightly higher pressure to prevent hydrocarbon ingress. As you can guess quite expensive so where conditions permit open sided is preferred.

We do the same on offshore platforms, but the sprinkler system is specifically designed to keep the hydrocarbon equipment cool to prevent escalation, which is what would happen on board a ship, a roof mounted sprinkler system would cool the outside of a car so if the fire was contained to the initial car then it would stop the heat from that car igniting adjacent vehicles, but if, as shown in the Luton video, you have a fuel leak under the car and this is burning this could run under other vehicles setting fire to those, if a petrol car tank was then to leak you may get a vapour cloud which when it gets to a certain mixture would ignite. If you where designing a system with lots of fuel storage tanks you would make sure they were all bunded, vented to a safe area, etc Part of the problem at Luton was that the hand held extingishers failed to operate thereby allowing the fire to escalate. A day after there was a taxi van fire at the pick up area at Glasgow airport but this was contained, but hey 2 diesel fires at 2 airport car parks and the issue is EVs

You could ask MMM to ship you one.of These

Burning petrol/diesel/oil floats on water, so can continue to burn, look at offshore accidents oil can quite easily burn on water. This runs under other cars and continues to burn, meanwhile the overhead sprinklers only cool the body work and not the fuel tanks/lines exposed to any flames under the car, this then adds more fuel to the fire, which the water can even help to spread the burning oil. Offshore the fire monitors are foam monitors, the foam making a barrier between air and the oil floating on water.

Paul, this any use to you We were checking my mates Moki 215cc which was quoted at 13 bhp at 4,300 rpm, he had a 3 blade prop on it turning at 4,100 rpm which equated for around 12.5 bhp, so it seemed to match pretty closely.

No IO could give you more, the overnight window is sort of the minimum, you just plug it in and tell how much you want by when. For example we have our Mini set for 80% by 8am, just plugged it in tonight and IO has scheduled the charge from 5pm to 7:30pm (it's only a little battery), you get a notification on your phone, but it means that during that period all you electricity is at that rate, so we always time plugging in before we cook dinner (every little helps....). Only works with certain cars and wall boxes, although our Mini is OI Go compatible we use our Ohme wallbox to interface with IO and the car interfaces with the Ohme (tells it what charge it has). It's not actually the car doing this but the phone app, so if you don't have a compatible wallbox then your car app would interface with the IO app, in that case setting a schedule on your wall box may override the allocated charging periods defined by Octopus. It all sounds a bit complicated but it isn't, literally takes seconds to set up and then you just plug in and away it goes and does it's thing. I think it's a contractual condition that you let IO (now IO Go) control the charging as they are scheduling the charging to balance the grid. Here's the screen shot of our current charging (ignore the miles this is based on Mini pessimistic Guess O Meter, it will actually be good for around 100 miles on 80%)

Another thing to consider is whether blast overpressure was design consideration, the heat would cause an increase in hydrocarbon vapours, when this reaches the lower explosive limit (LEL) then you basically get an explosion which causes a significant over pressure, it is part of the design of an oil and gas production facility to ensure the structure can withstand this, as is the safe routing of hydrcarbon vapours from vessels subjected to a pool fire. The sprinkler system also keeps the vessels cool to prevent the steel from weakening which could lead to a Boiling Liquid Expanding Vapour Explosion, but in these systems the sprinklers are mounted directly on the vessel. In a carpark they would be spraying the body work and not necessarily cooling the fuel tank, so maybe you would need ground based sprinklers under every car.
