Status: offline 		The DVDs are for those who want to set up their plane for excellent flying, contemplating IMAC type flying or competition in general from the aerobatics perspective. However there are also 3D maneuvers and fairly complex topics such as preparing unlimited unknowns and sequences as well.

pvavon@hotmail.com for additional details (she sells Avon as well, by the way)

I'd like to thank Brad for all the hard work in putting this together.

All the best,

Don

Status: offline 		Hey Don - Great video! In the video you mention that only a small amount of sub-trim should be used or else the servo has a hard time finding center. Could you please explain this in more detail? I understand that you do not want to use sub-trim when trying to match servos, such as a dual elevator setup, but does it really matter if only a single servo is used per control surface?

After 20 years of modeling I finally learned that there are an odd number of teeth on the servo drive gear which allows one to rotate the servo horn 180 degrees to get a better geometry if needed. Unfortunately, I already snipped off the ''wrong'' side of the horn in a few applications which forces me to use a large amount of subtrim to get the linkages perpendicular.
Thanks,
Steve Insalaco

Status: offline 		Steve, good deal and all the best with flying. Finding center-not so much as servos moving at different speeds. Sub trim is a function that moves the servo to get the control arm generally centering. This in conjunction with end point adjustments can have an adverse effect on servo speeds. You are basically stretching the number of steps for the same amount of travel, among the servos. I was at the FARM club helping out a giant scale newbe last fall and he was flying a third scale H9 Extra 330 with Futaba 8 channel and Hitec servos. One of his servos literally trailed the other one by about 20 or so degrees when moving the elevators up and down in a rapid fashion. He said a servo was bad. Actually, backing up a bit- when he was flying he asked my help to trim his plane and handed me the transmitter. When I tried some waterfalls, it peeled off really bad. When I landed that is when I saw the elevators moving at different speeds. Upon inspection I found he used the electronic sub trim to get the servos aligned and massive atv end point to get the ends the same throw. He also had the ATVs set at nealy 150 percent. I think he was like, off one complete servo arm tooth and used the sub trim to get the servo back to center. After about 2 hours getting everything mechanically adjusted, the plane flew so much better. It went from something nearly crashing to a competitive IMAC and 3D setup. Any case, I had an identical experience when helping a flyer in Vanceboro, NC last year (after the pattern contest completed). Exact same issue on his (scale) plane. He thought the Rx was bad until I showed him what the deal was. After mechanically adjusting to get it close, all was well. That''s why I emphasize that in the video, since I''ve assisted several flyers with this issue.

Have a good one!

Don

Status: online 		Don, thanks for making this video. Lots of good info for everyone. I know the focus is IMAC - scale aerobatics, but a lot of the tips and info can apply to lots of different types of flying. Something for everyone.
