I left the stock rear wheels where they were and have not touched them at all. I assure you they are straight and perpendicular to the plane (should I move them closer to the Center of gravity?). Iwanted to make sure just incase I changed to another prop, there would be ground clearance as well plus it was much easier to do it this way. What I did was modify the front wheel so that it is attached to a coat hanger which is bent foward to get the front of the plane up (you might notice how long it is, it some stock the same lenght as the rear wheel wires). After I find the right angle/hight for it I will bend the front wire straight and cut it to size and then permantly attach it to the front landing gear. It may look like the rear wheels are bent but I assure you they are straight. They probally look like that because of the extreme angle the plane is at for photo purposes.


P.S. What is LHS. Ihave seen this acronym before but have yet to figure out what it stands for.






ORIGINAL: opjose

You appeared to have angled the rear ( wing mounted ) landing gear backward, to change the angle of attack.

The problem with this is you are effectively changing the point where the plane rotates with respect to the C.G. as the nose tries to come up.

This is like putting a big weight on the nose just before takeoff, but removing it once in flight.

So it is not a good idea.

It is better to either shorten or bend the wires themselves a bit.

Typically we use a "V" bend to shorten piano wires when used in linkages, etc.

You may be able to do the same to the rear landing gear wire.

I'd use a wire bending tool to get this right and matched on both landing gear wires.

At worst you can go to a LHS and grab similiar piano wire and bend a new set of rear landing gear.
