Well engine run complete and a brief taxi test. Test flights coming up next month.

Also was out with my buddy Jack Lowe who had his new scratch built P-51 out for an engine run and some taxi time as well,

This little beauty has a Kolm 100cc inline four stroke gas engine that sounds fantastic.

I have a bit of time prior to the taxi testing and flight testing of the 104 so I thought it would be a good time to service the A-10 landing gear.
This gear is very scale. The oleo is air over hydraulic and the brakes are a disc pack like the real ones.
At the end of last season I noticed that one oleo was  a little low on pressure as it sat a bit lower on that side of the plane.

Here you see the disc as it sits in the wheel.

It is a beautifully made little unit. It sits on the splines of the hub which you can see in the picture.

Once the gear is off the plane there is a valve at the top of the oleo that must be in the upright position or you get covered in hydraulic fluid. There is a little plunger that comes with the gear. You suck up some hydraulic fluid into it and once you have released the air from the unit you can remove or add fluid to the oleo. After that you can add a set amount of air in the strut (this varies depending on the model) and you are done.
Now resembled and ready for another season of flying.
