Default RE: Impact

Well, the Impact has been flown. I got about a dozen flights on it this weekend. All that can be said is wow. Dry weight is 9.8 lbs, with a Mintor 170. Things I have found with my setup.

Incidences: Tail/Motor at 0 degrees Wing at .25 degrees positive. Recommended (Tail at .2 to .3 degrees negative – Wing/motor at 0) I opted to do the incidence change on the wing so that if it needed to be changed it would be easily accessible. If you do it the manufacturer’s way it makes it pretty much impossible to change without a butcher job.

CG: Set at the front on the recommended CG range (1/2 to ¾ behind wing tube) right at ½ behind the tube. The plane flew tail heavy and I needed no down when inverted. So I shifted some things around and got the CG just behind the wing tube. The plane flies much more solid there and requires a small push when inverted.

Mixes: Right now I have no mixes and I’m not sure if I will program any. There is a very slight tuck to the gear in knife edge. And I mean very slight. Up lines and down lines are very straight.

There was a pretty good crosswind yesterday and the plane seemed to handle it very well. I just applied the proper corrective rudder for a straight line and the plane just grooved.

My throws are as follows.

Aileron: High Rate 1in up 1.25 down – Low is 65%
Rudder: High 2.75 in - Low is 50% (Rudder is very/very effective)
Elevator High Rate 5/8 Up ¾ down – Low is 60%

As I find out more I will let you know. Patternboy I will be getting some pictures for you very shortly. I will put it side by side next to the Focus ver 1. I have had some problems with the media card in my camera.
