> overheating is a possible issue
I have often wondered if the nikasil cylinders for the VW would help with
the marginal cooling of the heads. My answer, without a shred of empirical
knowledge, is that it would. Back in the 60's my Ducati racer had a copper
gasket between the head and the generously-finned cylinder (aluminum with
cast iron liner). I was told by 'Ducati experts' that the cylinder drew a
lot of heat away from the head.
The nikasil cylinders would certainly cut some weight.. 10 lbs IIRC.
Wonder if ceramic or other engine coatings would help with the head cooling.

Having built several Corvair engines over the years, while they can be made quite
bulletproof, all the ones I have ever seen in aircraft use are tractors, so
they can be easily cooled. As a pusher, cooling is going to get a lot more complicated.
Besides; they are just too heavy.

Great Plains Aircraft sold the nikasil cylinders for the VW for a few
years. They talked about the weight savings and the cooling. They now say
that they didn't work out. Never heard the why just that they
don't recommend them any more.

Hi Bill Sullivan & others,
I have a FireStar with 5-rib wings just like yours. I built it and tried
to keep the weight down per Kolb's instructions, i.e. go light on the
paint; use sun block in the paint rather than the silver stuff, etc. My kit
came with the skinny 1" diameter gear legs and plastic wheels. My buddy built
a FireStar KXP with the same gear legs and wheels. He bent the gear legs
on the first landing, so I opted to switch over to the fatter 1-1/8" Dia.
legs before I flew mine, which was in 1994. We both think that after
getting some experience, we could probably have used the skinny gear legs. But
one place we wanted to fly to required brakes because of a downhill pavement
taxi-way. Installation of the go-cart brake kit required the use of the
heavier duty gear legs and the wheelbarrow wheels. This added weight. My
wife suggested (strongly demanded) that I install a parachute system. I
got a Second Chantz unit which I think was about 12 lbs. or so. Again adding
weight, but with the idea that the parachute was less than the 24 lbs.
allowance and the extra could be used to allow for the heavier gear, brakes
and wheels. I didn't weigh the FireStar at that time, so no idea of the
weight in that configuration. However, later on I installed a 3/4 coverage
Lexan windshield and at that time I did weigh it at 275 lbs. empty (Bathroom
scales).
Seems to be a lot of different opinions about whether or not you can use
the allowable weight of a parachute for other items. But at the time I
built mine, the Kolb brochure stated that a parachute might be needed to make
the 254 lb. weight, which seemed to reflect that you could.

Following Jack Hart's guidelines, I think you could come in well under the
weight limit. If I ever get to throw some money at mine, I think I can
come in around 270
