I tried hard to find the horror in your post but was unable myself. I must not have the proper context.  ;-)

Thats a lot of steel shot to lay on a little varieze

The previous "raptor" is not to be confused with the kit being designed and built by Keith Murphy of Raptor Air Works (unfortunate that the two have essentially the same name).

This Raptor is a design based on the Rutan VariEze but incorporates a steel tube structure surrounded by a composite skin.  I am interested in seeing how the weights go, but this, so far, appears to have reasonable expectations with a reasonable price tag.  

This will be a really cool aircraft when brought to life

OK.....15lb ham here........no way to make it kosher

pneumatics not a good choice. Reliability poor in cold weather. Blow an internal O ring on one of these cylinders and you will be screaming

(ah, with a sound of that ole camaro airing out the carbon) I would think

that the thrust is a real kick in the pants.

Many congrats!! Now come the just rewards...........the opportunity to grin unconvincingly at the TSA agents knowing that they are no longer the bitter anticipation, but the memory. Blue skies slinger

CF spar caps.....the bend-to-yeild charactaristics of these over fiberglass

are different. I am a big fan of a light bird though, and I would personally like to use carbon in a few other areas but......it's a precious material to experiment with,

Excellent method of triumph over the "heavy" spar. The weight you saved is only gonna shine when you start your weight/balance. You cast off a bunch...

This fuse set-up looks like its going to be lite-lite-lite. Love what you are doing, keep it up!

thats right edge, you change the dynamics when you lengthen the tub. I thought this through before stretching, and I know I won't be carrying around ballast like a cozy. I just wanted the extra room in the back for luggage!!

just curious about overspeeding a prop, you know, mach at prop tip=!@#$%^

That was an interesting short article on the v-8 conversion, seems he addressed many areas where weight became the issue. I am personally going with the 13b with crook redrive. I am stretched 13" (firewall to canard) and will undoubtedly have some fun when it comes to weight/balance stage.

The doggone fuel burn is good, and camII racing fuel could easilly be exchanged for the 100ll. On pint engine oil in 4800 miles is absolutely awesome. I am wondering how he is capping his RPM? Rev limiting?

Can't help but think I saw a velocity at RR last year with a spanky V-8. Had a fighter rumble, but remember seeing heat blemishes on the prop where the hot waste came out of the cowl. Only drawback I see is loss of coolant at altitude........doubt it would keep purring like a rotary would. Funny thing, I thought the fuel burn at 200 would be closer to 16 than six:D

there is a warning about tryin to do that on the plans supplied for the

roncz canard...............nope!!!

No those are some cool cad's!! (Did I detect the usage of carbon on the

center section spar?)

Where I live, those are 1979 prices!

Benifits of the design? (Hum) Supposing you cannot glean sufficiant power from one piston per cylinder? I am thinking that the distribution of power to the crank at two points is of little benifit......perhaps a nice power plant for a irrigation pump?

KISS=(KEEP IT SIMPLE STU___!) An engineering principal which has proven itself time and time again. (Oops, I think I slipped on a banana peel)

thats one heck of a test to put on a yacht, wonder what would have happened if you allowed this one inch bubble to grow while you answered

the phone or something...........yachts in space/:rolleyes:

maybe Santa got caught up in an ill fated investment with madoff too!

Too all though, as always, a very merry christmas...........and yes, the greatest things have always been free:)

Girls.....now I know you could pull it off,

*****Arrived back home from assignment in washington D.C. and, on the doorstep, was my freshly fabricated engine mount for a Mazda 13B!! Inside the generously constructed shipping crate was the base for my winter

project......powerplant. Thanks go out to cozy girls for knocking this little item out in quick time.........it will offer an excellent diversion from laying floor tile!

Flying off the 40 at this airport would not be the end of the world, but it

would establish a precedence which other airports might follow=not good.

It was unfortunate, tragic, a black eye to all GA aircraft. To single out

experimental aircraft as unsafe would be like declaring the FAA whom deem them safe for flight testing are unqualified as well. This guy has a bone to pick, wonder what he would say if a G5 went down in similar fashion?

Hding ones landing gear inside the aircraft post departure has its benefits, and with a composite canard aircraft this whole idea poses a multitude of problems. It would be easy to speculate that for every 1000 aircraft, perhaps

2 might have retractable mains? These are experimental aircraft, and designing a set of retracts which will handle shock loads of landing and still hide seemlessly away inside the aircraft presents a sizeable challenge. There are a couple options out there for "out of the box" gears sets, none of them are without their own shortcomings. Stationary gear legs with nice pants are the easiest and most cost effective method of solving the question of retracts or not., if you just have to have retracts, good luck!

icing the cake!! Its all downhill from here
