Hardnut

I have a Miniplane and became frustrated with the trim on the U/C coming off. I have since used plastic page binders on mine and have also added them to the N struts. Fuelproof, the correct airofoil shape and smart looking to boot. I'll get a pic and mail it here.

Is anyone having issues with 2strokes overheating inside the cowl? Mine flies fine without a cowl but as soon as I mount the cowl the engine gradually tightens and is clearly getting too hot.

I'm using a Webra speed 40 with a bisson pitts muffler and it has enough power to hover my mini.
