  1. It looks like you have lost the push rod guides, these could be made out of a section from an old telescopic aerial. They will need o rings top and botom to seal them. As mentioned above the screws are very likely BA on an engine of this age.
  2. The battery is there to keep the model memories up. Unlike other makes that use EEPROM which needs no power to retain its memory, JR chose to use a system that has to have power to keep it live. The battery eventually runs down and needs to be replaced but doing this usually means that it loses all its models.
  3. Some of the higher quality metal servo arms have a pinch-bolt to ensure a proper fit.
  4. Wasn't there a fatal accident on the flightline in Spain fairly recently? You'd think this would shake some sense into your local junta.
  5. I don't think anyone fixed it, it's just that the server is in a good mood for once.
  6. B&Q sell something that is identical to Depron... https://www.diy.com/departments/diall-polystyrene-6mm-insulation-board-l-0-8m-w-0-6m-pack-of-8/1906880_BQ.prd It comes in 3 thicknesses, 3, 6 and 9mm
  7. Bigeard, Mylar is a polyester film made from stretched polyethylene terephthalate (PET), pop bottle material. It comes in sheet form on the roll from Mike Woodhouse in thicknesses from 1micron up to 12.5micron. It's a clear film that also can be silvered. It heatshrinks like iron films but has no adhesive and it can be attached to an airframe with Covergrip. I have used the 2micron which is very flimsy, the 5 micron is easier to use. When applied under tissue so little dope is needed, it comes in lighter than tissue alone with the additional advantages that it's completely air-proof and puncture resistant.
  8. Be careful wetting the structure if it was built using PVA or other water-soluble glue as the structure could easily just fall apart. There was a magazine article about some old geezer, when ever he crashed his plane, he used to put it in the bath to separate all the bits so he could rebuild it from scratch, this could of course have been the April edition.
  9. OK now, thanks.
  10. The cookies thing pops up randomly so if you click back when ever you get it then click on the link you want it will eventually go there.
  11. My DB Ghostrider 50 would occasionally stall into an unrecoverable spin so I put small upward tilted ply tabs near the tips of the wings which completely cured the problem. It seemed that the issue stemmed from the small fin area because the design was originally conceived to be used with galloping ghost control.
