Chip,

I have some wheels I got from my HPH 304CZ. Do you

know the size you
need?=
I had to special order them and have since sold the

glider.

A point that doesn`t seemed to have been raised concerns the protection
of the underside t/e of the aileron when landing on a hard runway and
unable to keep the wings level until the glider stops.If a bit of
inadvertent stick against the wing going down occurs at the last moment
before stopping damage will occur.In this case a skid of up to 40mm deep
may be required.


..... that was at the back of my mind when I was asking about fitting a
wheel in one of the wingtip skids sold by Glasfaser. They make two types:
35mm and 50mm deep.

I've just ordered 35mm skids. This is on the grounds that I fly off grass
both at home and anywhere else that I'm likely to visit lands on grass
even if it has a hard runway. Consequently I don't want to fit a skid
containing a wheel because doing this is likely to fill the skid with mud
in damp conditions. Of course,

35mm may just be enough to keep the ailerons off the rocks but I'll check
whether the ailerons are clear of a hard surface. However, if it isn't
and I find myself going some place with hard runways I can always glue a
rubber doorstop with a reshaped mounting face onto each skid as a
temporary measure.
