  1. Paul, leave it on methonal, it's not the valves it's the seats that need to be hardened, methonal burns a lot cooler than petrol at the expense of greater consumption.

    Just my thoughts ( hope Jon jumps in and backs me up)but I would carry on using the oil ratio recommended, I think a lot of trouble comes when modellers try to extract the absolute maximum out of there fitted engines when a larger engine ran below of its capabilities would give far less trouble and last longer.

    I only fly vintage jobs now but I do like to use a slightly larger engine than recommended and run them rich and undercompressed ( diesels obviously!) partly due to my mechanical sympathy but mainly because spares are unobtainable...just my thoughts.

  2. Soft valve seats, it was never designed to run on petrol.

    You may be lucky and find someone to fit hardened seats but realistically your looking at new heads I'm afraid.

  3. I use the little waxed paper pots that are used in McDonald's to put your ketchup in, they never seem to mind me taking a few ( probably polite to buy a burger though!).

  4. Hillclimber sir, give George at 4max a ring ( sorry can't do links) but he will give you good advice, you really don't need a lot of power with vintage types.

    As to covering, don't use film, totally out of keeping in my mind, my local model shop (addlestone models) has a roll of vintage cream tex in stock, saw it my self only this morning, that would look lovely with maybe some blue trim ( humbrol enamel?).

  5. Just finished and flown this, offered as a free plan in the mag recently.

    My model is rudder only and powered by a Irvine mills. 75,

    If you've read the accompanying article in the mag you will know this was Vic smeed's last design, pleased to report it flys like a dream, covered in polyester silk and dope with tissue trim, finished weight is 14 ounces.
