yes but if the power is off so is the mobile mast, however some appear to have generators at the foot of the mast, so perhaps not.

So called " Driving aids" on new cars , help or hinderence ?
john davidson 1 replied to Engine Doctor's topic in Chit-chat
Applies servo pressure to all four brakes, you can feel it on the brake pedal taking over and slightly depressing it. Just crossed my mind that I learned 60 years ago o double declutch AND heel and toe at the same time, like patting your head and rubbing your tum at the same time. Car tests of that time often made mention if the brake and throttle pedal relationships allowed heel and toe. Allowed steep hill starts if the handbrake was weak, which it often was! -

The electronic hand brake on my Nissan works very well, best of all it works on all four wheels and unlike well publicised occurrences on normal handbrakes on some other makes , never fails when the brakes cool down, A club mate is a Ford mechanic and he related a case of an electronic handbrake failure like the above, The vehicle was winched onto a recovery but they could not get it off so had to just cut the cables. Cost one thousand pounds to repair. I kept this in mind when replacing my old Volvo but the tech on the Nissan has been tptally reliable after seven years, touch wood. Still park with it n gear though! -

Parking on pavement infuriated my wife when she was a childminder, out with a double buggy and another on foot. She ended up walking on the road in traffic with them. Worst was builders vans, etc. they think that gives them the right to block the pavement all day nearest to their work. -

My X Trail has cameras below the door mirrors as well as front and rear, so can give a "birds eye view" when parking so you can line up exactly in the middle of a bay. That is the single aid I would have above all others -
What's flying over your house
john davidson 1 replied to David Pearce 4's topic in Full Size Aviation
Has come over my house several times heading for Scone, engine at almost idle but still shifting some! -
I have Harrier 809 from the library just now. Reveals some of the skullduggery behind the scenes politically and the likes of assistance from Chile , the USA and France to the British. Also covers a bit ot the Argentinian story too. Recommended.

Just to expand on that, the esc (speed controller) will cut power to the motor when in use to prevent damage to the lipo by over discharge. They can then either be left at storage charge if leaving for a while , or charged fully ready for use ( but not for an extended length of time as this can cause deterioration) . Important I feel if expensive lipos , not so much if small capacity cheap ones

RC Croups website?

Use sign shop self adhesive vinyl to cover the depron, make ribs and a depron spar , use one sheet for top and bottom with the top wider to allow for the top curve, Cover in one piece flat, groove the fold point then fold with a batten to support the depron. There is a tutorial on U tube by Graeme Dorschel. the result is an extremely strong ding proof wing ideal for your purpose. Not sure if vinyl is fuel proof though.

not a guru----Inteesting link quoting 3 to 4 year old Evs at one third of new price. Also comment re lots of cars coming to end of lease, so could be a realistic buy for a private owner On the theme of tax on EVs, government must be thinking about road pricing given satellite tech. Just wonder how easy it would be to evade although lots fo cars seem to be not taxed on the present system.

slave channel 7 to elevator channel 3 should fix it

Began flying with a rudder and elevator Junior 60 and was then given an old Mannock biplane . First flight was a huge shock as left aileron made it smartly turn right and never having used the left stick up to then, was lucky to get it back on the field. CAR was the only answer at that stage in my flying career

Woman in my local sign shop only laughed when I asked for offcuts. Their vinyl is reasonably priced I find although I haven't been in for a while so like every thing else probably in for a shock when I do.

Well done! Similar planform as my YF22 and similar roll rate too. Enjoy. -
Electric models can bite too.
john davidson 1 replied to Cliff Bastow's topic in All Things Model Flying
Tuning needle valves is perhaps more dangerous, too near the spinning prop, that is why many engines began appearing with remote valves. Speaking from experience ---needed a hospital visit years ago after touching a prop when reaching for the needle . I fly solely electric now and I am very careful and try to follow a safe routine, -

Transporting models to the field
john davidson 1 replied to Learner's topic in Flying Field Reports and Chat
Heard somewhere a while ago that drivers who wear name tags on a lanyard , in a crash the tag flies out forward to be met by the air bag , then severely impacts the wearers face , edge on too, ouch! -
Just fitted up an ARROWS VECTOR gyro unit to my BAE Hawk, seems identical to the above. Printed sheet provided is rubbish however, no similarity to the actual plug positions. Onto You Tube and carefully followed a tutorial successfully so all ready for the next session at the patch. This is my second Hawk, first one had one too many frantic searches for the sticks on self launch so this should calm things down. Weather for tomorrow looks dire so might have to wait for the weekend.

Spring is here again - who's been flying?
john davidson 1 replied to GrumpyGnome's topic in Flying Field Reports and Chat
Had a gallon of glow fuel self siphon into the boot of my car once, one more reason to use lipos -
are the planes included in the price?
