After discussions with Vans and other Cablecraft assemblers, I have found the following. The standard cables as supplied by the kit manufacturer are rated for 200-300F and the contents of the cables then soften and melt with summer temperatures after shutdown. These are industrial grade cables. They are about $70-$80 and last several years, and then the controls begin to move with difficulty and must at some point be replaced. Cablecraft also makes aircraft grade cables that are rated to about 350F and cost 2-3 times the industrial. I am going to order them which are supposed to be airworthy for life of the airframe. This seems preferable to changing cables at 500 hour intervals. In the meantime I am ordering a throttle cable from California Push Pull to install until the stainless cables are ready. YMMV but when the T, P,M controls start to become difficult to move or jerky it is time. I have already replaced the original cables several years ago.

Two additional points of interest:
<![if !supportLists]>- <![endif]>If using push/pull controls the throttle cable Van’s recommends is too short (47.5”). Get the one Van’s sells for the RV-7 IO-360 (50.5”).
<![if !supportLists]>- <![endif]>Agree on the heat issue with any of the cable options. Where the cable runs near the engine I put it through a small diameter piece of fire sleeve, like Aeroquip AE102-8.

Did you look at McFarlane for cables? They offer RV-10 specific cables in aircraft grade. They have PMA for some Cessna and Piper, and now are OEM supplier for Mooney. I don't recall exact pricing, probably between $250 and $300 per cable. Teflon lined, first rate construction.

California push-pull is a Cablecraft assembler. The cables I spec'd previously were $60 to $70 each 2 years ago. I believe the ones I ordered are rated to a higher temp than the Vans supplied cables, i.e. to 350F. The marine cables seem to have more stainless than we probably need for aircraft.
