Default nosegear

i am trying to find out how much travel up and down the nosewheel is capable of . also, does anyone have any observations or data on how the distance to the prop changes during the travel. any help appreciated.

Suggestion... Place airplane on saw horses to suspend gear and kick front tire and see how much it moves fore / aft.

You might be surprised...

When I was in the nuke industry I had a particularly brilliant engineer working for me that was always coming up with new and expensive inspections we could perform on our steam generators. I told him that if he couldn’t tell me what we would do different based on the results they were a waste of time and money. He grumbled, but it did reduce the number of science projects.

What would you do different based on the data requested?

Watch the RV-12 gear tests that Van's did on the RV-12, the nose gear deflection upward on impact looks minimal vs the splayed maingear. Looks like a flat front tire would be worse for prop tip to ground clearance than nosegear deflection from a hard landing.

Come on guys. If you cant grease this thing its time for a new hobby.
Even in that old video with Mitch flying the -12 he mentions that this is without a doubt the easiest landing plane he has ever flown. I agree. It’s is not an off airport Stol

My concern would be if you got a flat front tire, and landed, would you have enough prop clearance to not have a prop strike?

A heavier motor is something Van's might not have envisioned, since they designed the plane about the weight of the Rotax 912 series motor, as an E-LSA.
