The one of a kind Simitar plans as jpg files

Some of the files were too big to post here.

Some didn't scan well due to being pencil drawn on the back of other plans.

Tight Turns,

Claude

Thanks to Alan Galinko for these

scans of the Simitar 2100 plans.

The Simitar 2100 is basically a double sized, 100 inch wingspan, 540.

The model would really be a performer with one of today's gasser engines, or today's electric systems!

Tight Turns,

Claude

The only pictures that were taken.

At a Simitar core cutting demonstration I had at my workshop on October 25th.

My wife was to take more but got distracted.

Anyway, with building season fast approaching here in Indiana, USA, I'm laying up some cores for myself as well as cutting cores for a few others.

I've got to get two more of last year's projects out of the way first.

More pictures in a week or two.

Tight Turns,

Claude

I flew a simitar back in the late 70's. After a 20 year break from RC, I'm flying again. I'd like to get another simitar model. After reading some of the previous posts and doing some on line searching it appears that nobody makes kits today. I haven't seen any kits or new/used models on RCGroups, eBay, or the other RCxxxx site :-).

I'm usually a ARF builder (assembler). I have put together a number of kits but kit building is not my thing. Any suggestions? Does someone regularly make wing cores? (and sheet them?) After reading on here an unfortunate experieince with the AMA cores I'm not egar to try them.

Do you know of any site that regularly has models for sale? I'm looking for something in the .40 size range.

Any help would be appreciated.

Thanks!

Unfortunately I don't know of much in the way of what I call Plank wings . I recently
saw this for a AMA add BigWing but its not for me . I have
followed Bill Evans stuff all of my modeling carer and have designed some of my
own planes because of the lack of anything to purchase . I am using a Favell airfoil
instead of the Scimitar . I like both airfoils . One thing I have noticed is careful attention
to the leading edge is very important .
As far as finding someone to sell you a built plane this is probably the best thread on
RCgroups or anywhere to post . Good luck

fast

shoe horn a 60 in any of the 40 sized ships and hang on. i've done this with severial ov bills birds and they tend to out run most of the raceing class
you do need to be on your toes on landing becouse of the extra weight, but dont worry, they maintain all there great handling, just faster. as for structure you must avoid trying to beef it up no need they are more than strong enough.
later and enjoy

A couple of links for wing cores.

http://www.compufoamcore.com/

http://www.flyingfoam.com/launch.html

For a powered plane, a symmetrical airfoil will work just fine.

I installed an OS 61 FX on my Pole Star and it's a lot of fun.

My Simitar Classic has an OS 65 LA.

Both models enjoy nearly unlimited vertical, but will slow down to a crawl if asked to do so.

The Classic is a lot of fun to fly in high winds, about 1/4 throttle and hold the nose into the wind and it flys backwards.

Tight turns,

Claude

Simitar wing cores

I can now cut wing cores for the Tracer 40 and Slo Motion. I can cut about anything else you want as well, just ask. Shoot me an email or private message if you need a set.

I'm Building Again. A Zippity-Do-Da this time.

I was going to try to build more than one model at a time, but work and other matters have been taking from my building time.

I'm building this Zippity-Do-Da with the intent of turning it into a training aircraft to be used next spring.

As always, please post your questions here.

Tight Turns,

Claude

Polestar EPO wing

Claude,

Tell me if I'm wrong, but I think the wing on the plan is a mirror image of the wings I see on both pics of the EPO : the leading edge has more sweep on the pics, more or less as much as the trailing edge on the plan ...

Any idea where the center of gravity should be? Is it okay to take the average chord and put the COG at the usual place ( as on a straight winged Scimitar, i mean)?

Best regards,

Kris G

P.S. attached is a pic of my Wiseguy, built from a sketch ( enlarged from the plan in RCM). It used to be powered by a OS 45 SF with pipe, now with by a piped Webra 61 speed.

I didn't notice it until you posted.

I'll put a note on the posts, I hope no one has cut cores for this yet!

I'll fire an email off to my friend in Louisville, KY to confirm.

I would balance as you said, as all the other Simitars at 12-15% of MAC.

Nice wiseguy!

Tight Turns,

Claude

The answer to the question is yes.(the plans show the wing mirrored, i.e. the front is the back etc)

To my knowledge only two real EPO's were built, Bill's and mine.

Expert Pilots Only, wasn't chosen lightly. Its short span, big elevons and weight/power make it a serious ship for fun, but not for twitchy fingers...(course that's why dual rates were created :-).

I like the planform and the way it flys, the plane comes in for a landing with the nose very high sort of like the SST. Landing with a n empty fuel tank really helps get that look...or having the tank just over the CG works too :-).

PoleStar X - PoleStar X EPO

There is a picture on page 6 of this thread, originally coming from Strykaas on RCU, but put there by Ed Moorman, showing a very similar configuration. It mentions the Pole Star X,but looks a lot like the EPO. Does anybody know what the difference is? Could this be a 3rd EPO in existence?

I am sooo happy there is finally some more information on this very exciting looking variant!

Best regards,

Kris
