Hummel's engines are running (according to their website) 37 and 45
hp
at 85 and 84 lbs (is this with exhaust?

According to some, a _full_ VW, with stock heads, putting out a constant
45 HP will melt it's valves in somewhat over 5 minutes.

I'll ask Scott Casler (Hummel Engines) about that. Anyone out there run a
Hummel 1/2 VW?


Best advice out there? Look for a plan that has many copies flying,
that
you can walk up to, and look at, and fly. Talk to the people who have
built them.

My guess is that the Texas Parasol plans that you have downloaded will
lose on at least one of these requirements.

Found a thread posted hear in early '06 that raised some issues about the
Texas Parasol plans. One was the issue of wing strength. I'm thinking that
as I'm trying to keep 103 leagle (as close as possible) I should end up
near
the estimated safe gross of 500#. I'm also thinking a substitute of 2024T3
instead of 6061T6 might be a good idea on the 2" spar.

The other problem of longeron/ landing gear yoke placement I guess will
take
some thought. Has anyone come up with correct measurments?

One suggestion that the 1/2 VW generates too much vibration for such a
light
frame seems valid. I'm begining to believe I'm going to have to abandon my
hope to use the 1/2 vw for a 103 leagle aircraft.

A friend had recomended the Texas Parasol to me as it met many of my
desires
and he said there was a lot of people who have built them and a lot online
resource. I havent been able to find the people or the online
resources.......

Looks like I may have to find a new design (haven't completly given up on
this yet however). Would love to hear from people built and flown these
(especially near 103 leagle weight).
