Cowl for Sig Super Chipmunk

I am building a Sig Super Chipmunk and would like to know if anyone has available a fiberglass cowl for it? THANKS, Gary.

If anyone does come up with it. let me know. i will be building the super chipmunk this winter. Or, even carbon fiber would be great.

I have this kit and was specifically told to ditch the ABS parts as well. This is also true with the Sig Mustang. The plastic just adds a lot of weight. I wondered if it was possible to do a lay over using the existing cowling. I figured the increased diameter due to going over it was miniscule. I would think using lightweight cloth and finishing resin you could probably replicate it pretty easily. I've seen Bob Zambelli use a similar procedure to make spinners and cowls himself. It would certainly have to save some weight. I just wondered how it would withstand vibration. The arf Oriental has a fiberglass cowl which after due time starts to shed cracks from all directions where the screws penetrate. I feel this is more than likely the same with the arf Nobler as well.

I have built two and used the cowl on one of them. Got curious and weighed one. Right at 1.8 oz with the holes cut out.

In the past I've made several cowlings and sets of wheel pant halves using old PET soft drink bottles. Carve and shape a wooden plug, cut off the base of the bottle and wedge the plug inside. Start shrinking the bottle with a heat gun. After a little practice you'll start getting good results. Light weight, repeatable and very inexpensive.

Just build it. This plane in not a world beater stunt ship. It is a good flyer. If you fly Advanced or Expert then you would biuld modern ship. Good luck on the build.

Dankar,

Sorry, but I disagree. The Sig Super Chipmunk if very competitive. The differences come in trim and ajustability. Many times, people who would be building the kit, are advancing and learning at the same time. Properly trimmed, it is a very good flying plane. Keys are light weight and good consistent power, as with most competitive planes.

It is an excellent plane to learn on or for the more advanced flyer, to compete.

Also, between Myself and McClellan's, we built a lot of them and pretty much used the stock plastic cowel with no problems. Proper fit is crucial to not developing cracks around mount screws.

I've reduced or eliminated, the cracking around the screw holes, of the mouting locations on, FibreGlass or Plastic Cowls, by glassing a washer on the inside, of the cowl at the holes location.
