Perforated release film... you can make it yourself with a pinking wheel used for sewing. Fewer holes generally your leave more resin in the cloth..more holes..bleed faster. Perforated film and then

Eugene, those look like nice parts. Did you use peel ply? I don't see any. It's very useful and explained in the education section of the plans. Sam

If the crankshaft is in question it should be pretty easy for any decent machine shop to cut a billet for you. The company that Nitrides the crankshafts for Corvair conversions are not outlandishly

Another thanks for explaining the details of the autoclave process. Reading about fires up my composites and materials enthusiasm big time :-) I could probably chat for hours with you guys! About the

Thanks for the explanation! I never did autoclaving myself, although I prepared some fiber-metal laminates to be autoclaved. A related question: AFAIK, a low percentage of voids (below 3-4%) has

Eugen, sounds to me like you're doing a thorough job. The only remark I want to make is about the 0.27 MPa foam compressive strength. Some time ago I found a paper that showed how anisotropic XPS can

I like the idea of using the Briggs & Stratton Vanguard engine, especially since there is so much racing experience and aftermarket parts. I am installing a new engine in my Q1 and going in a similar

Solid numbers and sounds like a great flight! Corbin -- Corbin N121CG

Hi @all, thanks for the hint about the corners and the necessary of form it with a sanding block. This area is manufactured exactly according to the plans, it’s listed in Page 7-6 Contouring,

A Vanguard V, Briggs and Stratton. They are used in auto racing....with of course modifications to the innards. https://www.youtube.com/watch?v=6NJo_g0Fo6g This is Briggs & Stratton Slingshot

The mains are fine, the rudder is fine. For me, the root cause is speed control. These slick little birds want to go fast. My main challenge is speed management.

Eugen, Everyone is right about the sharp corners and the cloth wrapping them. Guidelines on how much rounding of the corners is needed can be found here:

Great report, Sam. Cute, smiling granddaughter makes everyone smile! Glad your cranial flight controller was in good shape and you now have those additional points of reference to add to the

Oh she's a cutie for sure Sammy! Looks especially happy to see you to! Bet you had a great time! Nice! 185 ground speed! And oh well 133 coming home but you got to enjoy you Q200 for a little

Charlie you're starting to sound like Jimmeh also! Getting them done and keeping them simple and to plans will get you in the air sooner. I flying them is sweeter than building. No really! Bruce

Nice! What engine will you use? Yep you will get a lot of sanding in the process! Bruce

Great picture. J

Sam, with your updates what makes the Q such a challenging bird still...Is the root cause the width of the mains? Or is it also control authority with the rudder? Some combination? Brian

By "new", do you mean anyone with less than 2000 hrs? :) Glad you had fun and were able to demonstrate your skills.

Great report Sam, what a cool Grandad !! You certainly have a few hours experience. Thanks. Rich T.
