There are shows on TV about your type.... hoarders. If you are in this hobby for 10 minutes you will start your own pile of used and abused. No reason to take someone else's pile. My house if full of just the new stuff I bought. My time is worth something... and likely more than the effort it would take to get rid of this old "stuff" (another word really applies). Old Cox engines... even when brand new they were mostly a pain to keep running. Stop kidding yourself... save the space and rush this stuff to the curb and don't think about it again.
Would you trust a plane on Kraft servos? come on.

That's some great ''advice''

(just the trainer part and finding a flying field )
KaiasPapa the radio parts might be worth at least a few $ to a vintage radio collector...Kraft parts are not junk. ebay them, and the engines, and you can get a few bucks towards some new equipment.
The old Cox engines typically sell quickly and easily there. The Spitsy has been modified, but they are not all that easy to find, so you can at least sell it as a parts engine to a collector.
Here is a forum just for small engines:

A LOT of us ''ancient''

modelers started with the small 1/2A type engines...they can be a real learning experience...
