The Beercat is actually the name of a Reno racing biplane that raced in 1969 and '71. It is part of the Texas Air and Space Museum collection. Now, is the Midwest Beercat modeled after the racer? Have to leave that up to the experts--though it sure seems similar. Thanks,

Thanks Ed, I'll buy that. Have tagged this plan as scale now.

Hi from an Aussie living in Thailand. First, thanks for all the wonderful plans. Now for my dilemma, I think the balance point for the BEERCAT is wrong. If it were a low wing tail dragger the plan's balance point would be very close, but as it is a Bi Plane with a stagged top wing it will never fly as it is tail heavy...a lot. If I accept the balance point to be in the same place on the top wing cord it seems perfect. Interested in your opinion.

Not sure my opinion on this would be worth so very much. I've spent no time flying models with reverse-staggered biplane wing layouts :) I'd wait for smarter people to come along. But meanwhile certainly a search for Staggerwing on Oz will show quite a few similar designs you could compare the CG with those plans?
SteveWMD - 23/05/2017
I'd say it's rather nose heavy. Following the 30% rule of thumb you could move the CG back to nearly 50% of the lower wing. That's roughly what other staggerwings use. But maybe it's better to stay on the safe side and try the shown position for first tests.

Balance point is correct for a negative staggered wings biplane, make a comparison with other similar plans like Beech 17 (more than one) on Outerzone.

Original photo of the full size Beercat, which could be useful [more pics 003].

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
