  1. My 2017 Xtrail refused to start a few weeks ago, changed the battery ( £150) , no issues, stop start began working much more so this could be used as an indicator of battery health if only you knew? Mind you my old much lamented SAAB had a voltmeter which left no doubt.
  2. Reinforced sticky tape. cut into 30mm lengths two lengths stuck together to make 50 mm long ( with one reversed( ,made into figure of 8 hinges ( four hinges per surface). Easy version of sewn hinge !
  3. Four cell lipos which have a duff cell cell are near enough to 12 volts so can be discharged with a bulb. I use such old lipos as a power source for LED day running lights on my old Triumph then dispose when flat. Nearly all vehicles now have these LEDs so I feel more comfortable that I can be seen by car drivers, always a worry on a bike. I once put a lipo in a bucket of water then pierced it . It boiled away for a while under water, showing how difficult to extinguish they are. Just the once!
  4. If I see a disposable Vape on the pavement I pick it up and dispose of it properly by separating the battery,Following the possible re-use with interest,
  5. They control the vortices from the tips which cause drag
  6. Or the bad news , we have amputated the wrong foot, -------- the good news is the man in the next bed wants to buy your slippers.
  7. Not flying demo for obvious reasons!
  8. As I have said before converting to electrickery the main problem is enlarging the tank bay to fit a battery up against the motor mount , otherwise the cg is too far aft. My Christen Eagle had a wide cowl so managed to fit a battery transversely , the cg was spot on without ballast.
  9. Thanks Ron. Just wondering if this could be adapted to depron? Balsa veneer is stuck to foam cores with PVA , or perhaps use water based varnish . I do use vinyl from the local sign shop which makes the wing almost bomb proof but brown paper would be cheaper and also sandable and would take emulsion . Worth a try any way
  10. Shelf life for poxy seems to infinite
  11. Cut the fire wall off and extend the tank bay to make a battery box, thus bringing the cg forward.
  12. I have managed to lose three,one trying to fly the wrong plane in formation, one looped on launch into the sun and one too far away, is this a record?
  13. They will usually loop in intermediate, release at top of loop for an Immelman
  14. I have a rather jaundiced opinion about most insurance, other than essential such as house and car insurance, the companies try not to pay out if they can. Last year got a wood screw in a front tyre, too near the edge, the fitter said for a plug so bought another tyre, an all season as usual. Few weeks later, blow me, had the same in the other side so sent off for a packer of repair screws which screw in from outside. Added a touch of POR to help things and it has been 100% air tight, I have individual sensors in each wheel so can keep an eye on pressure which gives a bit peace of mind , tyres and brakes, really not best to cut corners but this fix seems a good product!
  15. My old boss was a wireless operator in '44 and '45, one of the ones he used to come out with was about the RAF pilot who was court martialed for chasing a WAAF round the station accomodation when he had no clothes on. He got off by quoting Kings Regulations which stated " An officer may dress according to the sport he is engaged in"
  16. Looked at the blurb for Glass, all a bit over the top for an over the top price, I find the Virgin TIVO box a boon as I can record and then fast forward all adverts or just simply mute until over. I think I developed a bad reaction to to ads during lockdown when no new ads were being produced and got sick of the monotony.
  17. Mention of a ROCKET THRUSTER PACK in the info no less, to put it under one second to 60, price is $250,000 or similar?
  18. Knowing what a farthing was, won my side a pub quiz, seems I was the only one in the room to ken.
  19. This was on Radio Scotlands Out of Doors program this morning so thought I would put it on. In Scotland sack is pronounced sek, plural seks Man went to B and Q to buy bin liners so went to the woman at the help desk and said "i'm lookin fer rubbish seks" She screamed and pushed the panic button so he got escorted out protesting
  20. As a private buyer, for some time I have bought at around two to three years old when the hump of depreciation has begun to level out. Looking ahead buying an EV at that age I would like to know the state of the battery as type of use,ac or dc charging, and being left at 100% charge is being reported as affecting life. Is a dealer going to report this? How would you find out to verify? It would greatly affect the value.
  21. Just googled Flying Legends to see that it is cancelled, no reason given. After the superb display last year I was committed to attending , must be some local problem. On the other hand Duxford is theming 80th anniversary of D day so might be worth the long trek.
  22. best watched on i player so you can fast forward the teddy bears, The Repair Shop is riddled with them as well.
