 |
|
Hello Gang,
I am evaluating different scenarios for my HDS taildragger gear. I don't like the idea of bulky gear parts sticking out of my leading edge.
When strolling through the archives I also found out, that installing the bungee gear is not considered a piece of cake for most builders.
the alternative would be a Grove gear. But these also have the reputation of being hard to adapt to a 601. plus they are quite heavy.
OTOH, I wouldn't want to deviate too much from the proven original design. My thoughts are of vehicle (motorcycle?) shock absorbers to replace the ole bungee assembly.
Has any of the gentlemen here heard or seen of anything similar already done?
any thoughts appreciated
Greetings from Germany

Peter,
After readings posts on the bungee gear installation for years and searching the archives, I was apprehensive about them too. When it came time to install them, I made the tool described in the archives - and probably on the 601.org web site too. Forewarned and with the techniques advertised by those who have gone before, the actual installation simply wasn't a problem. I used some dental squeezers to put the bolts into well reamed holes without much fuss. It really isn't that bad and help is available.

Hello Peter,
I honestly would not bother to go for the shock absorbers. While the
conventional gear boxes do stick out a little, the installation is
undramatic and it works really well. I also can take huge amounts of
punishment (I know, I had a few hard contacts learning to fly my HD
taildragger). A motorcycle shock absorber (what about the spring?) would
require proper hard points in the wing and good load distribution, plus
you would want it as light as possible. To go for that would be opening a
can of worms...
The spring gear is an option, but 10 kg penality over the conventional
design, and a bit tricky to fit. You would most probably end up with a
cluncky spring under the plane, even worse than the two gear boxes.
