What to get parents for Christmas.

My dad’s into RC cars, and I’ve already got him a few presents for Christmas but they’re kinda “boring”.

Wanted to get him something specifically for his interest. The man seems to have everything but I’m sure there’s something every rc owner things would be cool some little trinket or something or can always use.

Any suggestions in the like.. $25-$40 ish range that he may like? :)

I believe all he has is crawlers.

—- Now my mom on the other hand. She just bought a real car recently, a jeep willy. And mentioned she met a guy when out with my dad rc’ing, who ALSO had a jeep, and then 3d printed like a body ?? So essentially he has a little jeep rc car too. I believe she also has crawlers too, but can find some pics. Is there anything I can get for her so she can have a jeep body too?
