I can bounce mine up and down at least an inch or two by grabbing the engine mount and using engine weight.  Not sure how much to adjust until I run it up and down an airstrip or do a couple of bounce and go.  Same thing regarding the bungee - I could barely induce and bounce (if any) with the elastic bungee.

Got it installed. Relatively quick and easy job. Question: how much vertical movement do you have? Reason I ask is that mine seems to be very soft now. As in, I can get an inch up and an inch down of travel just by bouncing the prop end. Maybe I'm just used to the bungee where it wouldn't budge by hand...

Jon - I looked at your build/engine mount on your homepage - nice job!  Your engine mount doesn't look like it will be an issue at all for doing the steel bungee install/use.  Took me two shifts of about 1/2 a day apiece.  Digging out the engine hoist, finding straps, play with dog, cup of coffee, etc.  My engine mount required a bit of finesse and inserting everything from beneath the firewall/front strut support.  Looks like your stuff will drop right in from the top.  The kit does has been modified in one respect in that they no longer use the coupler nuts to adjust compression of the spring via the side straps.  Simply use the provided washers and self locking nuts.  I actually called Jan@Viking to confirm that was O.K. and it was indeed an intended change.  Simple install overall.  I did prime the spring and sprayed the inside of the strut tube with LPS anti-corrosive protection.  The top of the tube will be open to moisture (cap is removed) and I think drilling a small drain hole at the bottom of the tube as Jan suggest is a good idea as well.  I was a bit surprised by the scale and bit of rust inside my tube and I haven't had it outside of a dry heated garage since I started my project.  Hope this helps and good luck and good flying!!

Mine comes in tomorrow.  Any tips for the install?  How long did it take?
