  1. Jeffrey this my invader, its free flight but it should help you in getting yours trimmed, mine weighs just under 4 ounces, the cg is on the main spar and the only packing it needed was 3/32 under the wing trailing edge.

    I do agree with you about using to many strong bands, I only use 2 rather thin ones, I use those the postman drops!

    I bungee launch mine using a home made affair consisting of 10 yards of 1/8th elastic and 15 of 6lb fishing line, even at full stretch the wings show no signs of lifting off the fuselage.

    The most important thing is to have the hook in the right place mines 3/4" behind the nose skid.

  2. Good thread Doc, for the life of me I can't remember where Brian said about not using it on phosphoru bronze, sadly a bit late to ask him now, what magazine did write under the name of "the wizard of oz"?

    At the time it made sense to me to the point of never using it on bronze, oilte etc.

    I only ever use it to silence squeaky door hinges although I do agree about the smell.

  3. Just my thoughts but if your going down the route of adding a reduction gearbox then why not go the whole way and develop a engine that's "A true 4 stroke" with in sump lubrication? if nothing else it'll put a end to the how much oil is to much debate.

    The gearbox idea is a great one btw, surprised it's not a common feature on larger engines ( of any brand).

  4. You can substitute paraffin for white spirit, kerosene or jet fuel, apparently white spirit smells far less once burnt.

    Can't answer the oil question although I would only ever use castor as most of my engines are old and I feel it offers the best protection.

  5. I've lost the odd wheel in the past oh and I had all the carefully applied trim fly off from a Hooligan ( remember them?) in front of most of the club...I was only young!

    Years before I did find a mill's 1.3 complete with bearers and prop in the middle of a local common, no other signs of wreckage and I've always assumed it "fell off" ??

    Totally unhelpful and tongue in cheek but it would never happen with a glow or diesel!...sorry couldn't resist..wink

    Nah! Seeing what happens down at the field, you're right it wouldn't happen with a glow or diesel. Usually they just don't run at all.laugh

    Please, please, PLEASE don't let this thread turn into an electric vs IC battle!

    Tim.

    Of course not Tim, only my attempt at a little humour, no offence intended...apologies...
