RIGHT STUFF FOR REAL STUNT

Have you seen the ad in Tower's catalog for OS FP engines?   Says, "Build to run one way . . . FAST!"   They're right!   If you've experienced the dreaded "run-away" on OS FP, or LA engines, and want it to run right for stunt, I can fix it.  In 1984, I developed the liner re-timing that tames these engines.  Others are only now catching on.  Allow one week turnaround after I receive your engine.  Setup instructions included.  Send the engine PRIORITY MAIL to:

POWER SYSTEMS FOR STUNT

Click here for Double Star Maintenance Update

DOUBLE STAR ENGINES
We believe the Double Star lineup of stunt engines to be the best traditional type stunt engines ever produced, Period!  Produced by ex-Soviet aerospace engineers in Kishinev, Moldova, the 40 CLASSIC, 50 CLASSIC, and 60 LITE were specially commissioned by me for use in Classic models and modern 60-size planes.   All incorporate modern AAC technology, exquisite workmanship, and are very light. . . the lightest available in their sizes.  Production of these engines is regular, but limited, so they are often "pre-sold" by the time they arrive here.  You can cancel anytime up to shipment.  This year, we hope to have new equipment in place which will increase production.  Full repair and part services are available.

Double Star Engines General Operating Information

FUEL: All Double Star engines are of aluminum, aluminum chrome (AAC) construction. As such, they need less oil than traditional control line stunt engines. I use, recommend, and sell Sig Fuels for use in these engines. All castor, or high castor content fuels can cause overcooling, rough running, and even, paradoxically, overheating and lean two cycle running. This is because the needle has to be set very lean for the engine to run at all on high castor fuels. Set this way, less overall fuel flows through the engine, which contributes to overheating. Alcohol in our fuel acts as a coolant as it flows through the engine. At lean needle settings, less alcohol goes through the engine.

GLOW PLUGS: I have tested nearly every glow plug on the market, and the result is that the Sig R/C plug (p/n GP003) is clearly superior. This plug is supplied as original equipment in Double Star engines. Nearly all other glow plugs, including some popular brands, cause a power loss and sensitivity to needle settings. Stick with the Sig plugs, no matter what your experience (or your local expert) tells you. Trust me on this! The Sig R/C plug also improves performance of just about every other engine, including OS and Saito 4 strokes.

PROPS: The best props I've ever used are Bollys in the appropriate size. Second-best are the newest B-Y&Os. Third-best are cleaned-up trued Zingers. Zingers tend to load an engine more for a given size. For example, a 10x6W Zinger loads an engine about like an 11x6 Bolly.

BREAK-IN: None. People think I'm kidding. I'm not. I mean it, when I say, "Put it in the plane and fly it". On the ground, the engine does not experience the same cooling and loads as it does in the air. Ground break-in of a Double Star can actually cause premature wear. You don't break in your new car by letting it idle in your driveway, do you?

PROBLEMS: If you have a problem with a Double Star, call me, not your local buddy who has never run one and has nothing invested; however, don't call me -don't even buy a Double Star, if you:

1. Make your own fuel.
2.
"Know" your glow plug is better.
3. "Know" your fuel is fine because it runs okay in your Fox3 5.
4. Haven't followed the instructions here or those packaged with the engine.

 

DOUBLE STAR CLASSIC 40 - This engine is based on the Fox .35, but with greater bore and stroke, AAC construction, and now comes with its own muffler.  A direct swap into Fox mounts, it weighs the same too.  It easily turns 11X5 and 11X6 props on 5% nitro, and works best in 42 to 52 oz. models.

Double Star Classic 40-------------------$150.00
Tongue Muffler----------------------------$25.00
Head Shims---------------------------------$1.00 ea.

DOUBLE STAR CLASSIC 50 - The classic 50, based on the Tigre G-21 .46, is a direct swap into Tigre mounts.   It weighs 8oz. with bushing shaft and AAC style piston/sleeve.  Works well in 48 to 58 oz. models such as the larger Classic models (T-Bird, NAKKE, etc.), or such as the Stiletto 660.  It is delivered with DS lightweight tube-type muffler.

Double Star Classic 50-------------------$200.00
Tongue Muffler----------------------------$25.00
Head Shims---------------------------------$1.00 ea.

DOUBLE STAR 60 LITE-RING - This engine is the 60 LITE with a ringed piston and "bridged" sleeve ports to suit the ring.  It is aimed at the competition flyer who practices heavily, as the ring gives instant starts when the engine is still hot from a prior flight.  This version was suggested by Bob Baron, and he used the prototype at the '98 Nats.

Double Star 60 "Lite-Ring"--------------------------$250.00
"New" one oz. DS Tube Muffler---------------------$35.00
(included with new engines)
Tongue Muffler--------------------------------------$25.00
Head Shims---------------------------------$1.00 ea.

DOUBLE STAR 60 BB - The original DS engine updated with AAC technology, instead of the previous ABC, saving 37 grams.  Otherwise, it's a copy of the Tigre .60 and totally duplicates its performance and character.  Comes with light weight DS tube muffler.

Double Star 60 BB ----------------------$260.00
Tongue Muffler----------------------------$25.00
Tube Muffler ------------------------------$35.00
Head Shims--------------------------------$1.00 ea.

Double Star 61 LRE - The DS 61 LRE is the ringed, rear exhaust offering in the Double Star line. This is a very powerful, but classic running, stunt engine which is also incredibly fuel efficient, thanks to it’s unique porting arrangement. Weight, with included muffler, is about the same as a ST.60 without muffler. It makes a great engine for scale type models, as the muffler can be hidden in the fuselage.

DIXON CUSTOM FOX 35 - Engines are carefully fitted and various subtle changes are made to gas flow to increase power and smoothness.  The crankshaft is re-balanced to reduce vibration, socket screws are used for re-assembly, and each is test-run before shipping.  100's of Custom Fox .35's have been purchased over the last few years.  And . . . everyone kept thinking the one used in my Nobler was a .40.

Dixon Custom Fox 35 -----------------------$90.00
Fox Hemi-kit (highly recommended)----------$28.00
DS------- NVA-----------------------------$10.00
(Custom engine does come with stock FOX Muffler too)

Dixon LA .46: I feel like this the best overall control line stunt engine for those new to the sport, or those people who want a "set it and forget it" engine. It is tolerant of different fuels and props, and works very well on profile models like the Brodak Cardinal. I re-time the sleeve to get a classic "4-2-4" type run at lower RPM than a stock motor, and with more torque. Additionally, I add a Double Star NVA to the traditional venturi location, a SIG R/C glow plug, and a Double Star tongue muffler. Each engine is test run before shipping. Between OS FP's and LA's, I have done over 300 engines.....Never had a complaint or got one back!
 
Dixon LA .46 Package $150.00
Rework On Your Engine $80.00

Dixon Super Tigre .51: The Super Tigre .51 is an overlooked engine. However, it is an excellent, powerful engine that works very well (with rework) in 600 to 700 square inch models, from 48 to 65 ounces. I re-time the sleeve for a classic "4-2-4" run, and make a custom Delrin venturi which re­locates the Double Star NVA to its traditional position just above the crankshaft. I also supply a SIG R/C glow plug and tongue muffler. Each engine is test run before shipping. Len Bourel won Advanced at the 2009 Brodak Fly-In with one of these.

Dixon Super Tigre .51 Package                     $160.00

Modifications Of Your Engine

I am still providing re-work services on OS-FP and LA engines supplies by customers. (Some other engines can also be re-worked.)  My modifications allow the engine to run in a traditional 4-2-4 manner at lower RPM, allowing use of 5" or 6" pitch propellers.  Most people find this type of run to be more pleasant, more "traditional", and there is no need for special carbon fiber low-pitch propellers.  Most wood propellers on the market will work just fine.

     The FP-LA re-work consists of:

          Re-Time sleeve
          Correct-size Venturi
          Double Star needle valve unit
          SIG R/C glow plug
          Double Star tongue muffler
          Test run
          Return shipping in the U.S. and Canada

Total Price $80.00 per engine

Send the engine, Priority Mail, to:

                    Tom Dixon
                    P.O. Box 671166
                    Marietta, Georgia 30066
                    U.S.A.

Payment can be made by cash, check or money order.

The re-worked FPs and LAs work especially well on profile models.

All OS-FP or LA engines, from .15 to .46, can be re-worked. (The LA 60 is too heavy to be useful.)

Turn-around time is usually within five days from the time I receive the engine.
