Maybe the way to go would be a "thorn" style canard- and make it out of something really substantial.

Canards don't like doing the Loopty-Loop thingy. Past experience memory's..

Adding the wings are a lot easier than the fuse. Takes about ~1.5 hours. Here is the three view ....

Draggy? With Rutan's golden touch, still a winer / record setter .....

Extracted from AMSOIL/Rutan Racer

At the 1982 Reno Air Races, Mortesen and the AMSOIL Racer took second place, with an average race speed of 209.21 mph (336.69 km/h), just 0.3 seconds behind the winner, again Sundancer.

Mortesen then set out to break speed records. The first was the Class C.1.b (1,000-2,000 pound take off weight) 3 km closed course, which the AMSOIL Racer beat with a speed of 232 mph (373 km/h). The second record achieved was over a 75-mile (121 km) closed course, which was accomplished with a speed of 235 mph (378 km/h).

Nauga and Slopememo, thanks for your recommendations. Looks like I need to lift the bar a little bit higher now ......

I love that Thorn-style approach, just that my workshop is not equipped to carve that nice smooth wing yet....

I tried the bagged EPP on my ODS wing a few weeks back. They are very smooth, stiff and light. Best of all, they still bounce like the regular EPP. May be that's a better steping stone before "composite wing + molded fuse" .

Looks like that's something I need to give up for Canards. No problem, I think I can live with the speed oriented "Quickie Racer"

Don't know if the roll rate is OK with Quickie? Any one have experience with the speed400 Quickie available a few years back?

How about the ARES micro ground attack A/C, If I had had the money a R/C flyer in Fla. was selling the mold's for the fuse/center section and the right's to produce. I saw his gas jet turbine one fly and it was awesome, I have the 3-view's around here somewhere.

I always thought the Ares would make a cool sloper. I'd love to do a Pond Racer as well.

Trying to think outside the box here, but a few suggestions:

1. Make the front canards fixed (i.e. no moving surfaces) and have all control in the rear "elevons" (for lack of a better word) -- Not sure if this is feasible though.

2. Have magnetic/plastic bolt attachment for the canards with a super long and easily accessible/breakable servo lead, so that a serious landing will only knock the wing off.

3. Make the canard from EPP with Burly/NS to prevent damage, and the rear wing from foam/bagged/sheeted (if you feel like it).

Looking forward to seeing the outcome.

Steve

Years ago I built an AmsOil powered by an OS91FS ad you can see in the attached picture.
It flew beautifully,but took off from paved surfaces only.
The wheels position would pose serious problem when landing on slope too.
I think that every landing could be no other than a crash landing.
A czech modeler have done a model for AeroFly Professional de luxe simulator ,see the other picture.
It's not yet available,but will be un a short time,look at this site:

Thanks to Geode I've just been hunting down Rutan designs...

http://www.aerofiles.com/_rutan.html
Photos taken from the above page to avoid hotlinking

The Raptor, Ares and Pond-Racer look pretty cool Reading about the amosil Racer's demise is interesting too. Crashed at 200mph during the Reno air-races after entering dirty air behind another racer at 11 meters altitude... pilot got out with minor injuries thanks to Rutan designing the cockpit to survive 22G crashes...

Seems like the pond racer is a common subject for the powered bods too.. http://images.google.se/imgres?imgur...%3Dsv%26sa%3DN

Geode,

Sorry if this is a little OT, but what CAD package are you using.

I need to make the 2D to 3D switch and am looking for recommendations.

Hey Geode:
Not sure this is really helpful, but I like to fly power models as sailplanes on CRRCsim, and there happens to be a Rutan Quickie.

It does loop well, does tight turns, but the rolls are a bit barrely. Try using a strong launch on CRRC (1.5-2.5) plus 25-30 mph wind

PS the DeHavilland Vampire would make for some very nice PSS

Here you go sir:

Hi folks, thanks for all the info to Rutan's designs. He is really a legend. Looks like I will have quite a few PSS/Rutan prejcts line up in the queue ......

Geode
Only hoping I can build as many model airplanes as Rutan did on real airplanes

I use Rhino. Recently, I found "Blender" (http://www.blender.org/). Seems to be a power tool with great features and community support.
