I'm mounting my Extreme Landing Gear. The instructions say to "measure the axles as they are sitting. You want 1.5 degrees or as close as possible" The instructions go on to say the angle is adjusted by grinding the long end of the bungee strut.
Does that mean the outboard end of the axle should be higher than the inboard end relative to the lateral axis of the fuselage?
How do you measure 1.5 degrees?

Re: Mounting Landing Gear
You can use the tangent of 1.5 degrees. Tangent is the ratio of "rise" to "run". An angle of 1.5 degrees gives 0.0262" of "rise" for every 1 inch of "run".Tralika wrote:How do you measure 1.5 degrees?
To calculate your ideal rise, measure the length (run) of your axle, and multiply that by .0262. I measured our Extreme gear overall axle length at 9". Thus, a 1.5 degree angle would yield 9 x 0.0262 = 0.236" ideal rise over the full length of the axle.
To get your actual rise, measure the height difference between the inboard and outboard ends of the axle.
Compare your ideal rise to your actual rise. If the actual number is larger, it means a bit of grinding will help.

If just enough is really good, then too much ought to be perfect.

Re: Mounting Landing Gear
Shouldn't the inner axle be higher than the outer axle? The top of the wheel should tilt outward?
I have a small metal cube called a AccuRemote that electronically measures angle, tilt and bevel, digitally. Very simple to use this to determine the angle of the axle, relative to level ground.
