First off, John, you know damn well you are always welcome..

Now, lets do a little assuming type thinking here for a minute, 'k..
With the .25's it flys well, not a killer machine, but flys well.. How
go you think it would be with say,, .40's instead.. Only a minor
increase in weight but a lot more pull power.. And of course, a
definate increase in sound <YES!> Leaving all things as they are with just slapping on some .40's... Do you think it would be a
better performaning plane.. ? Do you think it would fly noticably 'heavier' ... ?
Bill, why don't you throw in your thoughts as well..
