Unfortunately I am not coming up with any easy solutions. It looks like you have everything set up correctly in the pictures (and there aren't really too many ways to "veer off course" here).

You may need to reach back out to Chris and see what he can advise.

One of the most important tips for improving speed is airfoils over the struts. Round tubing is very drag inducing. I don't know if Chris has it, but U-Flyit does. ABS plastic is light, but wood corner molding, or 2 strips of chair molding run thru a sander works good with a little router work. The leading edge of the strut isn't an issue, the trailing edge is. On my challenger it added approx 7-10 mph.

Please note; you will NOT meet part 103 requirements with streamlined struts.

Does anybody have any advice on setting up the CAMBER angle on the mains?

I asked Chris to add the F3 Cabane style landing gear as an upgrade to my F2 kit.

This was to add the 15 x 6.0 inch tires and better legs. Not really sure what gear comes with the F1/F2 kits anyhow.

I wanted to be prepared for any rough grass strips or dirt runways I may encounter one day. This should also give me a bit more ground clearance for my propeller tips as well.

I just finished painting all my landing gear parts and am ready to start on what is listed on page 31 in the 103 assembly manual.

Caught a break in the cold weather and managed to get my painting done before a large winter front sets in.

My question is, what is the purpose of the camber? Will the gear compress or sag as I add my weight to the airplane?

Anybody have any good pictures of the F3 type gear that you have set up?

As always, you guys are very helpful here and I appreciate it!

Set your camber for a final of 0 degrees (+/- 1 degree.) I like to set camber at -.75 degree or so so when it's at gross weight it sits at zero.

And there you go Bruce, from the man himself! Good to know info for my future F5!

I am curious as to why you made the highlighted and underlined statement.

My guess would be an increase in max speed. Curious to hear what Chris says!

Agreed. The prop may need to be changed to one with less thrust, or the throttle may need to be limited. I remember reading something about doing the latter, that the limiter must not be able to be changed from inside the aircraft. That was in reference to putting a limiting screw or bolt on the throttle itself in the cockpit of the plane. That would not be allowed.
