Matt,

My Q1 weighed 299# empty weight with the Onan ready to fly.
I only added 3 more rubber engine mounts to spread out the load on
the firewall. you can see them in the photos section. I had the
engine out of a Teenie 2.

Ryan. 424lbs. that is only 60lbs than the recomended maximum weight.
With pilot and fuel would the canard be strong enough on landings? Is
this the reason why you switched to tri gear?

Matt,

424# empty + [8gal.] 48# fuel + 180# pilot = 652# gross take off
weight.

60 horsepower vs. 22hp = 1100 fpm climb vs. 150/250fpm.

The main gear can handle the weight, I have bounced it, like a diving
board on a bad landing---still no stress fractures at the fuselage or
paint.

Fortunately all Rutan designs are over designed structurally.

I changed to tri-gear because after over 50 hours flying this type
of maingear I wanted something more reliable on landing.
The tri-gear lets me land and takeoff in 650' to 800' with no fear of
a prop strike or crosswind chalenges. I had to give up about 9/12mph
in top speed with the tri-gear.

Matt,

I had the VW engine sitting around. My point is that the engine
weight was not a problem for the Q1 airframe.

The VW engines have proven over the years to be a reliable Aero
engine.
