That is one problem that I've seen with ARF models. They do not give you fuel tank access hatches. I build them into all my kit builtup models, and it is a must in my book. It makes it easy to work on your fuel tank, engine linkage and get at your nicad.

I have built ARF's, and in every case I've painted on a fuel proof coating all the way back to the aft wing bulkhead. I will even pour it in the nose area, fuel proofing all the inner area, and pour out the excess. I find my models will last years if I do this. Yes it will add a bit of weight, but well worth the weight if a fuel tank breaks open...for it will save the model. K2R works wonders and I've used it for more years then I would care to remember...just wish I could find some here...

I believe if enough folks tell the makers of ARF's of the need to have fuel access hatches, they will build them that way. A few do have them, the Twin Star is one...but that model is no longer in production.

Soft landings always,
