Hey Guys, I've had to replace my stock cowl and there was and still is a huge shortage since early Feb on cowls. I just got the new cowls last week and the quality of the cowls are vary poor now. The stock cowl had some thickness to it and the new ones are thin and are so easy to break or shatter. I guess they need to make there money somehow  |

what I did with my original is apply some 3M extreme fiber tape to the inside. I don't think it strengthens it too much this way because the cowl is so brittle already, but when it cracks some more, it kind of stays together though and I don't worry about it.  Maybe the best sollution is to make a fiberglass cowl using a plastic cowl as a mould? dave mc |

How about spraying the inside of the cowl with white Plastidip in the aerosol can? this will put a rubberized coating on it. I used this a brittle lexan gear cover for my Evader BX and it strengthened it quite a bit.

Upon receiving my super-eggshell-thin replacement cowling, I carefully lined the inside of it with duct tape and trimmed out the ventilation holes with an Xacto knife. The cowling is a bit grayer than the rest of the plane, and the cowling still cracks, but it's held together through many unscheduled one point landings. The grayer look should not matter if the SC is painted, which I intend to do with my new SC.

Well I bought 6 cowls toady and put one on my SC for the maiden with flaperons and hit a chunk of ice while landing and nosed it in and there went the cowl. Looks like it hit a brick wall at 100mph! Not happy with them. I will have to mod the cowl too. Here goes nothing.

I never seem to get more than a few flights out of a cowl before cracking it up either.
I've completely reconstructed shattered cowls by patiently putting the pieces back together and then fastening with bits of packing tape. (Keep your x-acto knife handy!) Once I've gotten it back together, I go over the whole thing with larger pieces of packing tape on the inside and outside of the cowl.
If you take your time, you can hardly tell your cowl has been 'rebuilt' from only a few steps back. Just make sure you get all the joints tight, and be real meticulous about how you apply the tape. Also, in my experience the rebuilt cowls tend to last quite a bit longer too ... probably due to the fact that they've now got a bit of flex built in.
I treat myself to a new cowl whenever I happen to see one in the LHS, but usually I'm flying with a "franken-cowl". It's pretty funny ... I can have dozens of successful flights on one of my old beater cowls ... but it seems whenever I put on a new one, I do something stupid and crack it up.
