wxman... That's a great choice... Only thing I think the Mayhem really likes the
YS 110 type power.... I almost got a mayhem.. But got the Showtime for my 110

Don't get me wrong on the gear of the "Do"... The stock gear will break on harder
than normal landings, But she lands so light, so it's easy to make great landings...
I just added more epoxy and some triangle bulsa stock to the tank saddle area
from the block to that area... it's really easy... My gear came out once, out of many
many flights.. I ran out of fuel and could not get the nose quite back up so it
pancaked in hard. Other than that I've had no problems on the gear... ANd the "Do"
is a fun plane to fly... Reason for me in getting another 46 "Do" after my crash...

That Avistar will hover...... Mine hovered for a few mins with the 46FX 12.25X3.75
APC in it's stock form and a bit tail heavy...
