These are the largest tires I could find for a 6" rim. There may be some that are larger in diameter but they are also much wider and width causes a lot of drag for little or no improvement on t ...

I don't believe they are "monitoring" websites, like all good businesses they have services (web crawlers) that notify them when their name is mentioned in any web text. You could get the s ...

Typically you would mount them with he spade parallel to the airflow in level flight. When you deflect the surface you also expose the surface of the spade to the airflow and it helps move the surface ...

I don't know how they worked, I never installed them. I have seen them on a MKIII but I never tried them.

How did the spades work on your MKIII?

When I first flew my MKIII I was disappointed in how heavy it was in roll. After about 50 or so hours in it, I no longer noticed. I have since sold the MKIII but I do have a set of steel aileron spa ...

At about the 6 minute mark of this video there is a picture sequence of folding my MKIII. It is a little different than the Fire Fly because the struts do not hold the wing up, you have to have a stan ...

Wow, It looks like there was a whole lot of excitement for a short period of time. Sorry this happened to you.

Rick, your MKIII must have been different than mine because mine was not built to any aircraft standard. I did not compare the parts I received to the engineering drawings, I did not even receive dim ...

I agree, it is disconcerting to have a flight critical part fail. Please remember you are flying an experimental aircraft. It is built with non aircraft (approved) parts and not designed and built t ...

The way most rudders are constructed on Kolbs is the "ribs" are bent at 90 degrees at the ends and then riveted to the trailing edge of the rudder. When I was messing around with the trim t ...

Desser has had another 21 tire on their website for a while that will also fit on a 6"rim. It comes in two versions, one that has mostly smooth tread (just a couple of ribs) that weighs 11 lbs a ...

when covering the wings I found the trailing edge did not warp but the ribs bowed out of column. I would keep an eye on this when shrinking the wings.

FWIW

I folded the wings every time I fly. One of the checks I put into place is to put all the hardware into a little box by itself (no more or no less than needed). After set up, that box should be empt ...

I am in no way endorsing this engine and I do not have any experience with them but here is another option to explore.

Hello All,
I just noticed today that Dressler tires has a 21" tire for a standard 6" rim. They have it both in shaved and unshaved versions. Below is a link

Yes the airplane had a cowling, it was an Aeroprakt A20. I still have a 300 hour Rotax 912ULS for sale that is perfect for a Kolb. It would come with everything needed to make it work on a Kolb. En ...

Hello Frank,
I will search for a better picture but the exhaust has been pulled off of the aircraft already. The exhaust can is nestled under the gearbox with the exhaust pipe exiting downward on th ...
