Just picked up a "slightly" used 40% YAK 54 - Aviation Models (TOC)....overall plane is in very good condition, except for the cowl.

The cowl itself is extremely "thin" in terms of material thickness.....this is especially true around the inner circumference of the front of the cowl, where any more than a little pressure can / will result in the paint / cowl cracking. In addition, it appears that some of the laid up fiberglass on the inside of the cowl is "bubbling" away from the cowl body.

1) Anyone out there with this plane experience the same problem?

2) Any / all solutions you've come up with to "beef up" the cowl without adding a tremendous amount of weight?

I'm thinking of laying up some light weight carbon fiber cloth on the inside of the cowl but would sure like to hear what others have done / might do.

Thanks for your help,

Bill
