This compact controller can keep it's cool even during the most extreme 3D maneuvers. Talon 25 is intended for use in most 400-size helicopter setups running up to 6S LiPo or your favorite 3D foamy that pulls up to 25 amps. Despite it's size, it boasts an impressive 8 amp peak/3 amp continuous BEC, keeping even the most draining servos at ease. Talon 25 also offers Castle's industry-leading helicopter functions, not to mention easy programming using the Castle Link USB adapter (coupon for free Castle Link included). Talon 25 tips the scales at a mere 18 grams!

Notes from Dave: This is a world beater ESC. Now we can run high voltages in our smaller models with a small tight ESC from a quality manufacturer. I'm very excited to put one of these in my 5S, 16 ounce Stick 400. Sweet!

*RC HOBBY APPLICATION RATING: 25 amps for the duration of a single 4,000 mAh battery pack with the ESC in contact with a 5 mph airflow of 25C (77F) or cooler air. Controller temperature must never exceed 100C (212F). Exceeding current or temperature ratings may damage components and may shorten the life of the ESC. Always verify system current draw at full-throttle. Decrease load or increase airflow to decrease the ESC's operating temperature.

**Peak indicates amperage sustainable for most servos' current draw transients. Always confirm servo current draw before the first flight of the model.

SOLD OUT, ETA 2026

In the full-scale aviation world, the Very Light Jet category (VLJ) is comprised of small business jets that seat four to eight people. They give private pilots the speed to effortlessly zip past an ordinary Cessna 172 on the way to a weekend fly-in. With a VLJ, the pilot would be finished eating that $100 hamburger before the 172 even enters the landing pattern.

The design of our Raven is inspired by Terry Dunn's VLJ design published years ago in Fly R/C magazine. Although Terry's original design was a simple, foam park-flyer, it had great lines reminiscent of the VLJs that Cirrus, Sonex and others now produce - or even possibly Mooney, if they had ventured into private jets back in the day.

We based the size of the Raven around a 64mm EDF - a power system that's inexpensive, readily available, and has plenty of power for this type of design. It's mounted right up-top, in the air flow channel of the fuselage. From there, we massaged and reworked Terry's design, adding landing gear and re-engineering the fuselage to have a removable wing section. A little tuck here, a little snip there, and the Raven was born.

The Raven's wing is a snap to build. It utilizes our unique WEB-LOCK wing construction to lock in critical alignment locations. The stressed balsa skin makes the panels very light and surprisingly rugged.

We've designed the Raven's fuselage to be self-aligning, with a light-weight internal structure for added strength. Surrounding this is the outer balsa skin, which is strong, light-weight, and twist-resistant. Overall, this balsa/ply airframe is uncomplicated, lightweight, easy to build, and features precision laser-cut parts that fit together quickly and accurately.

Oh, and let's not forget that V-Tail. It's the Raven's party piece - the touch that gives it that unique look - its swagger - its style.

The wing is removable for storage/transport and for giving access to the radio/servo area. From there, you have easy access to install the radio and ESC. What's more, the fully assembled model can fit in the trunk of most cars.

Up front, there's a large hatch, which gives quick access to the battery and nose-gear. The hatch's spring-loaded latch makes swapping in a fresh pack a breeze.

When it comes time to fly, the Raven will surprise you in a number of ways: First, is the takeoff roll - it's shorter than you might expect!

Second, the Raven's wide flight envelope. It's just as much at home cruising around the pattern at lower throttle settings as it is tearing up the skies at full-throttle. Next is the Raven's surprising aerobatic capabilities. Now you'll never confuse this for a pattern ship, but Raven can easily perform loops, rolls, 1/2 Cubans, split-S, inverted flight and more - and most without needing a dive to start.

Lastly is the controllability. Even at very low speeds, you'll always feel that you have control of the Raven. And that controllability is a welcoming feeling when it comes time to land smoothly, slowly, and right down the runway.

Specifications:

• Wingspan: 47.25 inches
• Wing Area: 330 sq. inches
• Length (airframe only): 34.25 inches
• Weight: 1.7 pounds framed, 3.5-4 pounds RTF
• Radio: 4 channel with V-tail mixing
• Give 30+ in./oz. servos (Mini servos - similar to HS-5065MG

• 64mm EDF Power Unit (12 bladed unit - similar to Freewing E7207)
• 60+ amp ESC, 4S LiPo)

Features of the Raven:

Premium USA Hardware
Included in each Old School Model Works kit is a premium hardware package. We only source our hardware from brand-name, USA manufacturers to guarantee the best quality.

WEB-LOCK Construction
There's nothing else like it. Build our wings, straight and true - with a minimum amount of fuss.

Front hatch
This extra-large top hatch gives you plenty of room to access the battery. It's front spring-lock makes it quick to remove the hatch and quick to lock the hatch back in place.

Short Aileron and V-Tail Linkages
We've designed the Raven so the linkages are to be as short as possible, giving you positive, slop-free control. Exactly what you want in a high-performance design.

Design your color scheme

Download this sheet to design your Raven's color scheme.

Additional items needed to complete the Raven kit:

• 64mm EDF Power Unit (ESC, battery)
• Radio system with 5 servos (we used mini-sized servos in our prototypes)
• Pushrods: 6" pushrods for the ailerons and v-tail, 8-10" for the nose gear
• Clevises for the pushrods
• Servo extensions: four 12" for the control surface servos
• Y-harness for nose gear servo
• Wheels: one 1.5-2" (nose), two 2" (mains)
• Covering (typically 2 rolls will work, depending on the color scheme) 

Please note:

We've done everything we can to make the Ravem a fun and easy to assemble kit. That being said, THIS IS NOT A BEGINNER KIT. If you've never built this type of balsa kit before, you will probably experience many challenges along the way. The manual is not written for beginners - it is assumed that the builder has the skills and techniques needed for this type of build.

Due to high demand, allow at least 2 weeks or more for shipment.

The DU-BRO Fuel Tanks are known throughout the RC hobby for their incredible strength, reliability, and long service life. With over 30 years of 0% tank failure, these tanks have earned a reputation as some of the toughest and most dependable in the industry.

DU-BRO fuel tanks are designed to resist cracking, splitting, and deformation from vibration or engine pressure. They are even strong enough to work with pressurized fuel systems, making them a trusted choice for both sport and high-performance models.

Each tank comes complete with high-quality hardware, including DU-BRO's famous one-piece clunk, which features built-in fuel barbs to prevent fuel tubing from slipping off. This ensures a secure, leak-free connection and smooth fuel delivery during flight.

You can use DU-BRO fuel tanks with glow fuel or gasoline. All you need for gas use is the #400 Gasoline Conversion Stopper, unless you are using one of these tank series:

#690-#692 - Includes tubing and stoppers for both glow and gasoline

#795-#797 - Pre-configured specifically for gasoline use

Each tank's capacity is approximate and may vary slightly. Also note:

2 oz and 4 oz tanks do not have the protruding lip

All larger sizes do include the molded lip for secure mounting

These tanks are perfect for RC airplanes, boats, and other models that require a strong, worry-free fuel system. They are easy to install, long-lasting, and built to handle the demands of everyday flying.

Tubing:

2-24 oz. Tanks include 3/32" I.D. silicone tubing. For gasoline, purchase 3/32" I.D. Tygon tubing (not included)

32-100 oz. Tanks include 1/8" I.D. silicone and Tygon tubing for gasoline or nitro fuel.

Proudly Made in the USA, DU-BRO Fuel Tanks continue to set the standard for reliability, durability, and performance in RC fuel systems.

My personal Slow Stick Canard is a twin tractor. I have a 1000mm boom length and the CG is set at 1-1.25" in ffront of the main wing leading edge. I have never built one with a stock boom length (800mm) but I would start with the CG in the range of 0-.5" in front of the leading edge. The shorter the boom the further the CG comes back, the longer the further forward you would place it. I don't know where Bob Masterson's CG is set but I would thing it is similar to my 1000mm boom setup.
