Hi Michael,
Where did you get the sprung tailwheel from?
I was trying to get the plans/drawings for these a while back but couldn't
find any.
cheers

Hi John and Lasse
I have owned a Mk1 H36 since 1988 (G-MRG in the UK,
now VH-VRG in Australia). It originally came with an un-sprung tailwheel which
was useless on rough surfaces. The sprung tailwheel became available in about
1989-1990 and is very easy to fit.
The original H36 "suffered" from aileron snatch.
This meant that the stick twitched when you went into a thermal. To me this
seemed to be a benefit rather than a fault, but the authorities didn't like it
and so stiff return springs were fitted on the the H36 Mk II (and on the
HK36 as well) these springs are great for building shoulder muscles but the
Mk I version is much nicer to fly.
My UK engineer, Tim Dews (Airborne Composites)
fitted canopy helper springs. I assume they came from Diamond. They do make it
easier to open the canopy but they are not really essential. On my
Dimona, the springs are hooked into the seat belt fixing behind the seat. This
needed to be strengthened with additional glass.
A German club were offering a modification to add
toe-brakes and a pop-out tail-wheel coupling. I have no contact details for
this. The turning circle, although not a problem in Australia, is not very good
and means that you need to be careful at quite a few European general-aviation
airfields.
I have never had any airframe problems (yet!). The
first engine lasted 1300 hours and suffered from burnt valves. The present
engine (fitted 5 years ago) has a vastly improved baffle system but still
needed
the valves redoing - guides and seats - after about 300 hours.
Hope this information is of some use to you - it is
a really nice plane to fly.
Michael

Hey Ian!
How's it going?
If the MkII had the springs on the tail wheel and
helper springs on the canopy,
are there mods available for the MkI?
