EZ build profile stunt for my Evo 36 cl

[Tommy Swonke]

 Just purchased an Evolution 36 cl and looking to mount it on a profile stunt plane . Something easy to build and sturdy. I need suggestions and sources.

Sig Twister or Banshee.  Or even a Sig Skyray

Thanks James, I'll check those out.

I'm leaning toward the Ringmaster S-1 kit from Brodak.  Brodak recommends .15-.40 to go on it so I guess the 36 will work on it.

The Twister is good but the nose will need to be shortened a bit to get the CG where it belongs...or the elevator moved back (which is better yet).

The Brodak Cardinal profile would be a good choice built exactly as the plans.  It's an excellent flying profile.  I don't know if it's available anymore!

The Skyray is too small for that engine unless you want to fly COMBAT with it!

The RSM P-40 (Profile) is another good choice.

The Pathfinder Profile by Brodak is an excellent flier and relatively easy to build with a straight wing, like the Twister but definitely outclasses it as a stunt trainer!

Engine sizes are deceptive.  A 1950's-era 35 is just enough for a Ringmaster, but there are modern-day 20's that are too damned much for it.  That Evo 36 is a toned-down modern-day engine, and will be way more engine than a Ringmaster needs, and way heavier than you want.

Easy and sturdy would be a Banshee; shorten the nose a couple of inches (it was designed for a lighter motor) and leave off the flaps (because they're complicated, and if you're asking for easy-built you probably don't fly well enough that they'd be much help).  Or get a stunt trainer from Phil Cartier.

 A tad of perspective for some engines I just weighed
Engine weights:
Fox .35------------------------6.8 oz
with muffler-------------------8.2

Torpedo Green head----------8.0
Johnson CS-------------------8.7
ST G-21-----------------------8.9
Fox 36X Needle bearing------8.0
Fox MK VI---------------------9.2
OS .20 ABC w/E2030 Muf----8.9
Evo .36CL with Tongue muf--9.3

Are you looking for a kit, or to build from plans?
If you want to go the kit route, Brodak has several good
flying profiles in the warbird series. As well as several
other 40 size profiles.

If looking to build from plans, then Don Hutchinson's line of
warbird profiles are all great flying planes. We also have several
easy to build profile planes using Gotcha foam core wings
listed on the Ultra Hobby Products website.

Tommy,

EZ build would be ARF or ARC.

Nobler's are popular. Nobler ARF only 119.00 free shipping at Tower hobbies.

Kit?

The Magician from Brodak.

I think they are ugly as sin, and I have one, but guys rave about how well they fly. EZ build, no flaps. 89.00 at Brodak, while they last!  

Brodak Quick Overview:

Designed by Jim Silhavy, the Original
 Magician is Classic Legal. It features a
 wingspan of 43.25 inches, a wing area of
 407 square inches, and an overall length of
 32.5 inches. The Magician can be
 flown with engine sizes .25 to .35.

Charles,

"Edited" I don't think Brodak's information is totally correct. The span might be 48" or a tad larger?

[Fredvon4]

BTW guys Tommy called and told me he has a Early (die cut) Brodak Profile Oriental on the way

I recommended NOT fussing with flaps as he is returning re-tread and the complication of setting up flaps and the trimming adds complication to his desire to just learn to build and and sport fly ---no intended stunt competition--

I hope this is not bad advice

I also steered him to some few older Oriental threads about building the Oriental with a shorter nose for heavier engines

as I see the (kit/designer) intended Fox 35 is  typically 6.8Oz and His on hand Evo .36CL with Tongue Muffler is 9.3 Oz so ballance with the heavier engine is a building consideration in my mind

I am sure Tommy will appreciate any and all opinions and advice

Brodak P-40 arf or arc . Quick to assemble and they fly very well.

Fred, lots of people fly this with a LAS-46 which is 9.3 oz without the muffler so the weight of a Evo .36 should not be a problem.

[Tim Wescott]

Hey Fred:  I think that's good advise even for someone who's going to be learning stunt.  Flaps don't help you keep the center of the plane on the pictures you're trying to draw in the sky: they just keep the plane pointed in a direction that makes it look better.  If you have decent judges, then flaps won't do you any good until you're getting over 400 points or so in the pattern -- that doesn't happen until you're almost ready to move up to Advanced.

    To give further perspective, in terms of performance, this is roughly in order of stunt effectiveness/desirability. The effectiveness/desirability of  the 8.9 ounce 20FP is about 3x that of the Fox 35, and the weight difference is 8.9 to 8.2. .7 ounces to get 3x the effectiveness is a very very small price to pay and a no-brainer. If's FAR less than the weight of the fuel you would use (and in fact, the takeoff weight will be higher with the Fox compared to the 20FP, because you will need a good 4 ounces for the Fox and maybe 2.25 for the 20FP).

   The weight, over this range, becomes a non-factor compared to the performance. Same with various piped engines, the tiny range of possible weight is negligible compared to the difference in the performance. So you want to select your engine based on the performance or effectiveness and just put some lead on the tail or shorten the nose to accommodate the weight.

I've been using the Evolution .36 CL engine for quite a while, in five different airplanes ranging in size from a 34 oz. Barnstormer, a 45 oz. Oriental, two Caprices (48 & 50 oz.) and a Roadrunner. Most current, and biggest is a 50 oz. Roadrunner (620 sq. inches). It had plenty of power at VSC last year. Fuel is Cool Power, 10% nitro with 18% oil (all
synthetic). Props are typically APC 11 1/2 x 4 (at our field west of Denver- about 6,000 ASL). At VSC I had to change to an APC 12 1/4 x 3 3/4 to slow the airplane down. I haven't found the weight of the engine to cause major balance issues. These engines are typically a 1/2" longer than a Fox or some of the early classic engines. The bulk of the weight is further back than a Fox which, for practical purposes doesn't contribute much to create a nose heavy model.

The Barnstormer is really on the small side of what to use the engine in...definitely not a Ringmaster. A Twister is probably the smallest model I would use. Someone recommended the Oriental Profile. If I ever build one of those, it will have the Evolution 36. The next model I plan to build is another Pathfinder which will get the Evolution 36.

A few notes regarding the Evolution 36;

My engines are mounted to 1/8" x 3/8" aluminum so that different engines can be easily swapped into different planes for testing. As a result, I try to have the n.v.a. as close to the same location as possible so that there aren't a boatload of holes going through the cowling. The stock rear mounted n.v.a. doesn't work well for that so I drill the case for a standard front mounted n.v.a. (Super Tigre) and .272" delrin venturi. Also, and this is strictly my own bias, I don't like the look of the case with all those goofy cooling fins, so I machine the head round and sand the fins off the back of the case to match the machined head. This has the added benefit of making it easier to get a nice fit of the cowl when the cylinder head projects part way through it. It also brings the weight of the engine down to 8.2 oz.

Internally the engine is dead stock. I haven't experienced the high fuel useage people talk about. Using Cool Power, the Evolution .36 gets way better fuel economy than my Magnum 36, Thunder Tiger 36 or my Aerotiger 36..

These have become one of my favorite engines. I've got at least 6 of them, several with over 300 flights and they still have great compression, start easily, are powerful and give a great stunt run. Just don't try to run them on 10/22. You won't be happy with the results.

i am flying the Mike Pratt design "Force" with an Fox35 cut from plans
itīs an easy to build plane (straight wing), needs nose weight for proper ballance (so your engne will be perfect, i had to add weight) and flies GREAT. i am learning the pattern with her.
i know that Mike makes a short kit, so this is an easy one IMHO
