I wonder why they do not recommend their racing fuel in their RTR? They all have the same basic construction?? Maybe it was the fuel proofness of their plastics in their toys?
I didn't realize Cox fuels were even being manufactured anymore. Is Cox fuel being sold again? The extra nitro would cause the decals to come off, but the oil alone would do that. I would imagine they didn't recommend it because of how it made needle valve settings more tricky.... a lean run on 35% nitro would cook the RTR, or any Cox engine.
