  1. If you're using Imperial (UK) measurements a quart is 1.1365 litres.
  2. Paul is wanting to clean out glass jars!
  3. Cellulose thinners should work.
  4. Try Just Engines. They can supply engine mounts, test stands and fuel tanks (along with superb advice).
  5. Same for me. Someone "fiddling" again?
  6. I would suggest one from "Just Engines" . They do two versions depending on what size engines you have. Both are excellent and in my opinion better than the overweight, overpriced and over rated Sullivan. My Sullivan wouldn't even turnover an OS 200 FS whereas the JE turns it with ease.
  7. JR still produce TX's for less than £2,000 but the UK supplier doesn't seem to hold much of a stock, if any! I've been using JR since before it was available in the UK (bought my first set in Singapore) and have had excellent service except for one instance using a JR DSM2 DSX9 Tx which although made by JR used a Spektrum manufactured RF board where the problem lay. I also then continued with the "real" JR DMSS originally with an XG11 and later with a 28X. Keep the faith Peter.
  8. Perhaps OS should have a new distributor as well, then we might have a better supply of spares and new engines!
  9. I had that "rubber" coating problem on a couple of Panasonic cameras and managed to remove it with isopropyl alcohol.
  10. The two baffles form a cross (X) and do not sit on top of each other. The exhaust tube fits in the outlet of the silencer with the crimped end preventing it coming out.
  11. Did the paint smell of "pear drops"? If it didn't then it wasn't acetone.
  12. Not a good idea to use acetone anywhere near enamel in my opinion. That link Jon doesn't list any thinners or reducers.
  13. From my experience a suitable thinner for epoxy is iso propyl alcohol ( IPA) which shouldn't attack enamel finishes.
  14. This is from Mar 2023 AS guidance : The model may be carried out to the take off position by the candidate or a helper or it may be taxied out from a safe position in front of the pits/pilot’s area. Taxiing out of the pits is an instant failure.
  15. I glassed with 0.6oz/sqyd cloth and finish painted a BT P40 of approx 64" span achieving a weight gain of 4.5 oz. It was the only a/c I weighed both before and after but others were covered using the same technique so I would have expected a similar outcome.
  16. No. The catalyst is platinum or sometimes a platinum / iridium alloy. One reason they are expensive.
  17. Polykote was, I understand ,based on a resin called PU15 manufactured by a company called Furniglas. A large price increase and high minimum order value of the base resin was I believe, the main reason for the demise of Polykote.
  18. I've had very mixed results with it. The same paint from the same tin has proved very unreliable in its "fuel resistant " qualities. Even the colour seems to have different results. Yellow and blue seem reasonable but red is useless. The substrate also has an effect. Plastic and GRF OK but Solartex not so good, even after cleaning all surfaces with IPA. The best ever fuel resistant paint was, IMO, the long gone Powermax Polykote.
  19. US ton, commonly called a "short ton" is 2000 lb.
  20. Have you tried Model Fixings ? https://www.modelfixings.co.uk/cap_screws.htm#Cap Screws
  21. Supermarket cake icing and marzipan are rolled on a very lightweight plastic tube about 20mm dia. Perfect for servo leads, you just need to get your "pinny" out and start baking!😉
