Good going, rogermharris. May I suggest instead of pilot holes, perhaps just marking with the laser and letting the individual drill to their liking? Reason why I mention this is then one could adapt to an engine other than the Cox .049 tank or Testors .049 Red Head tank pattern. There's no telling whether someone might try a Sure Start, Testors .049 without tank, OK Cub .049-B, or other beam mount engine with engine mount, etc.

And please regard my comments less seriously, as although your product is high quality, at this point I don't have a need for this item as for now.

no worries sir! it's easy enough to make it both ways. i like the accuracy of pilot holes, especially for a beginner Thumbs Up

#32 or #33 rubber band preferred, those are 3 or 3 1/2 x 1/8, or #64 with care as the wider band can cover the edge of the engine and choke the intake. Those are 3 1/2 x 1/4 and are commonly used for RC airplane wings. Two rubber bands are used, one per pair of ears.

The screws are #3 as called out in the engine paperwork, with #2, #3, and in some cases #4 being acceptable. I normally use #2 as #3 are difficult to obtain locally for me.

The holes look small enough that paint or a drop of epoxy will fill them for re-drilling. Also the extra set of holes for the sure-start and horseshoe backs is missing, but no worries there.

I can make them however they would be most useful. It certainly would not change the cost.  If you would prefer I can  add markings for other mounts. what length screw 3/8"?
Here is one with marks only

Awesome work!  I'd buy a couple for projects.  I like the ones without the holes, just marked.  But even with the holes, I could fill them with a dot of glue and drill for other patterns as needed.  Or, maybe a compromise.  Put holes in the smaller plate the engine faces, and no holes in the plate with the ears that rubber bands to the firewall plate.  But, as you say, holes would work good for a beginner building their first planes.  Make them however you wish, and they'll be used to anyone's best advantage.

And for rubber bands, I'd definitely use #32 bands. A big bag is not too expensive at Office Depot or the like.

Don't mean to be pushy, just offering up suggestions.

i don't mind the suggestions at all. i will do this and basically give them away. i'm not looking to get rich, just want to help preserve this hobby. since i am just getting back into it after 35 years or so it pains me to have to order pretty much everything and to have to purchase something like this and $10 shipping is outrageous! i'll put them in a standard envelope and put a stamp on it. the biggest expense is the stamp!

anyway... i can figure that out later.. it will cost me about 20 cents to make

Wow, nice looking Red & White Lil' Wizard! How'd you get the mirror-like tank? Polish or production?

Roger does fine work!
Nice high grade 3 ply, looks just like on my original. His parts will be perfectly interchangeable with the original Goldberg mount. Very nice.
