Barry.... Well, It's like this.. The 100 is still in the 4*.. That maybe what
I'm flying in the funfly if I don't get the profile back together... I did try
the 15X6.... Guess I get a bit more speed, but the spool up seems the same
and I get more air with the 16X4... So... For me bigger is better))
I even got the ST out... But thought better of that for now..

I started on the "Do" but... I need to get another throttle linkage. I guess
from it laying on the table so long it fell on the floor and it took some damage
from my chair... That's what I get..

Kaos... Glad the mag is working for you.. I've seen one run good in our last
fun fly... But the three at the field is kinda iffy at low throttle...
Sounds like that's not the case with yours... You'll have a ball
Whats your thoughts between the two engines?
