Scale 50% Dalotel 165

[RCFlyingKnight]

Hey Roger, See attached picture for how I figured this was. I can't see this as a oil/air pressure dampening, more like piston pushing against a cushion. The dimensions I got for the strut is best guess scaling your picture for a 4" wheel.

My idea isn't fesable after actually drawing it out. Sorry I couldn't help,

Matthew

Roger....could something like this work? An inner (lower) strut sliding inside on 2 bushing in the upper strut, with slot machined to accept a steel roll pin. The roll pin captures the inner strut, limits the travel and prevents rotation.

Just thinking out loud!

Thanks Matthew for the effort, everything helps and the wheel is 8"

I will have a closer look at your drawing, this would work , now the question is the lower leg would have to be solid because of the slot, I will have to check about the weight increase

modified my order for aluminum, for the landing gear, should be here by next week hopefully

I would think that if the wall thickness is enough, the center could still be hollow. Another though, instead of a steel roll pin how about a high-density polyurethane/propylene pin. Or a smaller steel pin through its center. The plastics hold up to tremendous wear and would be substantially less abrasive on the aluminum slots. They also have self lubricating properties, if I recall.

If you go plastic for the pin, you might as well make it flat so the contact area is greatly increased.
I slightly modded Pistolera's drawing to explain my thought.

Good idea!

Thanks guys, I love these ideas,
