>How about a stock fatboy on an AT 18mm RMS E27?
I've flown my stock (except for a touch of nose weight) FatBoy on AT
18mm RMS D13 and D21 and it's a hoot (I call it the FastBoy on the
D21). I've never seen/used an 18mm E27, but I guess it'd be a
FasterBoy on that motor!. Lots of folks have built Fatboys stock
except for a 24mm mount to get bigger motors in, of course. Some have
gone to extremes and made HPR FatBoys.
Note, BTW, that the D13 and D21 are full Ds at 20Ns. According to the
Sprocketry chart the E27 is a very wimpy E, at only 23Ns. So don't
expect much more altitude out of the E27, just a faster takeoff.
