Putting together Pilot RC 40% Decathlon.

  • Wingspan: 150" (3.81m)
  • Wing Area: 3758 sq in (24245 sq cm)
  • Length: 101" (2.58m)
  • Weight: 39.3 lbs (17.8kg)
  • Engine: 100-120cc

This is my first Pilot RC model and first Decathlon so I'd appreciate any input/feedback on build components for scale/sport flying. I'm not into 3D or towing so no need for crazy power/weight ratio. Kit is ordered, working now on the components.

Here's what I'm what I'm thinking as build list -

- Engine: Saito FG-100TS
- Prop: Mejzlik carbon 27x10

Radio gear:
- Pioneer w/Micro Mag Switch
- iGyro SAT
- PowerPak 5.0X2 (PowerBox batteries)

- PowerPak 2.5X2 (Ignition battery)
- PBR-26D Receivers (2)

Servos (ailerons-2, flaps, elevators)

Servo (rudder)
- Hitec D951TW (2)

Servo (throttle)
-Hitec D955TW

If you're fan of Tundra/Bush plane/STOL scale flying, you may be wondering about various tire/wheel sizing & weight. What follows is a summary of some of the tires that I've tested to date.

For context, here are the full scale Alaskan Bushwheel options and the corresponding scale measurements

Tomahawk PZL-104 Wilga 35A is full fiberglass kit, constructed in fiberglass and carbon fiber vacuum-sandwich technology with servo mounts molded in. Ordered custom built 3.7m wing version with all available accessory parts (scale tailwheel with shock, scale cockpit, lighting system and protective bags) by Tomahawk Aviation USA. Also picked up the additional components including GfK fuel tank, servo linkages, tow release and scale pilot.

Should be a nice, slow, STOL, all weather big fun plane to fly!

The design is fully scale and is highly detailed - all rivets, hinged panels, panel lines and corrugated sheets are molded in glass fiber technology. Even the slats along the entire length of the span are reproduced exactly as the original - super scale :-)

- wingspan 3.7M (12' 2")
- length 2.7M (8' 10")
- weight (~51-55 lbs)

As a current Moki S250 owner I decided to try the new Black Star 5-250v3 for my new Tomahawk Wilga project. The specs look good on paper, turns the same props and my buddies new UMS 5-125 sounds awesome!

Tomahawk offers both the airframe and the engine and as a top tier RC company, they product parts, service and warranty so I figured I’d give it a go. Also, I’m very excited to get it fired up to compare the sound!

Here’s some unboxing pics -

Virtually the second this plane was announced, I jumped on the pre-order list! Big bush plane - yes please! Being from Pacific Northwest, I’m very partial to bush planes and have thoroughly enjoyed the Hangar 9 1/4 scale P/A-18 Super Cub (both gas & EP), Hangar 9 DHC-2 Beaver (gas & EP) and the 1/5 scale Carbon Cub (gas).

Most of the build list went together quickly and includes:

- Servo (aileron/Elev/Flaps): Savox 1258TG
- Taildragger RC servo extensions
- Rudder: Hitec HS-7956HR
- Rudder: Savox 1231SG
- LED system: Electrodynamics (Nav/anti-collision, wig/wag landing, beacon)
- IFlytalies instrument panel
- PR Bushwheel struts
- PR Bushwheel 8.75” (222mm) Tundra
- Air Top 200mm (7.87”) Tundra - Summer tires
- Jeti Duplex R10 Rex Assist
- Jeti Duplex Dual Mag Switch
- Jeti Central box 200
- (2) Jeti Duplex EX R3/RSW 2.4GHz Receiver
- Jeti Duplex EX R3 REX 900 MHz Receiver
- Jeti Duplex R7 Rex Assist

The hard part was power selection. Spent the better part of 2 months going back & forth between short list:

1. Saito FG-61TS
2. EME 70 twin w/auto-start
3. 12S EP setup

Finally pulled the trigger on the Saito...beautiful engine although twice the price of the 2-stroke gas and EP. Should sound more scale which is important to me :-)

Now that the engine is sorted, added a few things to the list

- RotoFlow - 16 ounce
- Tech-Aero Ignition BEC
- JC Super XCub prop

Let the build begin!
