The larger the disk is, due to the fact it only spins one way, increases the effects of three things that are not condusive to a good flying patteren plane. This type of planes sole purpose in life, is to make, long, striaight lines, with combinations of 1/4 loops, and half rolls in everyone, and I feel most will agree.

However the larger the prop is means more torque is created, along with increasing P-factor and spiraling slipstream. Those 3 forces that we all have to deal with are the reason I laugh when I here someone complain about a 1/4 inch bow in a fuse or wing. Or see some of the contraptions people dream up to make sure the right elev goes down the same number of thousandths as the left one. IMO A plane set up totally equal on everything along with being perfectly straight would not be a very tru feeling model due to those three things. I have set up airplanes with every thing from the clothes pin degree meters to laser levels and everything in betwwen in the past 6 months, and the one that has always provided the best flying plane for me, from the get go, was a steel ruler measuring in 1/32's of an inch. The reason it works so well for me is becuase, one day a few years ago I realized there are a few neverchanging things that all that are going to be in every single prop plane there is, that has just one prop spinning the same direction all the time. Once that became apparent my setup time and trimming process shrunk dramatically and I was very frtunate to not have to switch radio brands in order for that to happen<G>

I don't have time to go into much detail but if you start out with these things already addressed before your first flight on a new plane you will be way ahead.

1. All planes will roll faster left the right due to torque, so make sure you set your ailerons in the TX 5% less to the left from the start

2. Whether you use right thrust or not due to spiraling slip stream you will always need a throttle to rud mix to fly in a straight at varing throttle settings. Standard is about 3% and the direction is thrust dependant. I use very little enginee thrust so mine is always adding right rudder as I increas the power.

3. I have never in my life had a pattern plane that took 0 aileron Dif. They have all taken a degree more up then down, so dial it in at the house and avoid guessing when you get there.

There are some other little things like thottle to Elev. for straight downlines which all planes need, and 5% less travel down then up on the elevators, but I am beat and cannot get real indeapth as to why.

Anyway sorry to ramble but all of this stuff is directly affected by the size of that disc, and when I say affected I mean in a bad way. The only positve is downline speed is a little slower as a norn, but there are several ways to make that happen .

good luck and hope some of this might help a few of you with your future projects.
