    Hi Troy!

    Thanks for the info. I thought you would be toiling away on the next developmental stage of these engines!!

    Hopefully soon, I can find the time to get flying again. I am looking forward to running this little beast. I am still a little concerned in keeping it quiet though.

    Four blade props? I have some of the 18.1 x 12 two bladers but I just cant see how I'll shut the thing up with these paint stirrers??

    Also-one more question to any of you out there in pattern land.

    I have struggled with aileron differential for years. I am just not happy with the rolls. I have tried various design fixes-but about the only one that seems to work is to get the wing back to 0-0 ( which can be achieved by a few ways, design, mix or thumbs) Differential itself does not seem to work if the wing is POA ( well...it works for half the roll !)
    Another black magic fix appears to be to run parallel ailerons-but this only 'sorta' seems to fix it. I like the feel of equal% chord ailerons however.

    I am frustrated with it-I like my planes to roll as if they had a string up its ...........well you know!

    OK-any 'secrets' I need to know??? Very good elevator work fixes it ( hence my 0-0 comment)

    Tom
