Here's a link to what I did, go to post 354. I tried a bunch of different materials on mine, and found regular 1/4" K&S music wire from the LHS to be the best. The nose strut is a little different as it's not a pin, but the strut machined down. Took a little effort to cut it out and replace with music wire, but so much better now

Interesting, My YA nosewheel strut has a (shorter) 1/4" shear pin with 1 setscrew in the strut and 1 in the trunion. Maybe a design change late in life for the YA P-38??!!

I think you'll find you have to keep some power on in the final approach with full flaps all the way down. The stall is gentle but you can see it sink fast if your behind it so be quick to add power if that's the case.
I had one bad landing the second time I tried the flaps because I couldn't read the stall coming on soon enough. Coupled with a TH servo issue not yet diagnosed I was reluctant to add power for fear of cartwheeling it in. So the best choice was to let it sink and keep it level.
Flies awesome though, crowd pleaser for sure

Default Retaining clips

It's either a c-clip or a e-clip. Horizon sells them, but you have to know the diameter of the pin.

I donít think itís either of those. It looks like a two-piece clip that is press fit in place. It is solid all the way around.

The clips mentioned will work, I think they are metric. I actually put brass tubes and 4-40 hardware in mine. Makes it easy adjust to keep the joints tight, but not tight enough to bind. If you go clips you'll need to add washers between the clip and the scissor, or you'll be able to rotate the strut back and forth due to excessive clearances. As you fly it a bunch, they continue to loosen up. I've squeezed the scissor so it fits tight ( but not too tight), then shimmed the outside between clip and scissor. I've shimmed the gap, and eventually found hardware is the way to go. Keeps the struts nice and tight without binding
You don't even notice the mains, I left the nose stock as it's so visible

Just wanted to add my home field is pretty rough, and hard on the gear

Great advice! Iím going straight to brass sleeves with 4-40 hardware. The stock pins are pretty but not practical as she ages.

Thanks!
