One that would require a firm twist to open the handle.

They have a large surface area combined with a cup shape. This would in the least create a large pitch variation and adverse yaw if not opened on both sides. The forces exerted against the frame and hinge would be large given the long length. If the hinge did not give out, then at least a large stress will be placed on the subframe there. If the door did come off then the risk to catastrophic damage to the tail seems great.

I have been building a hangar for my Zenith 701, and my friend and I are trying to find a way to buy some plastic wheels for the doors. The wheels must have a V groove like this: http://midwestcaster.thomasnet.com/item/wheels-v-groove/pv-series-solid-polyurethane-v-groove-wheel/pvp-420-19?&seo=110&plpver=10 I have been trying to find a place to buy this kind of wheels but either there is no response from the company or the shipping cost is more than the price of the wheels. We will need 16 wheels and not necessarily with the bearing in the centre. We could have it with a plastic insert or even a metal rod for the bolt. If anyone can find a place where this product is available and for a reasonable price 10-15 $ pr/pc. plus shipping cost to Iceland (for less than $200), I would very much appreciate the help.

Just a matter of machining the grooves and drilling the center, then cut apart into wheels. If you can't access a strong enough plastic material of the diameter required, wouldn't steel be suitable??? Maybe a bit noisier, but very strong....

Just pull the long hinge pin out and off you go. If you do this be prepared to ride in a very windy cockpit. My plane flies OK without doors but we get plenty of prop wash.
