Pilot RC 40% Decathlon


Putting together Pilot RC 40% Decathlon.

Specs:
  • 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 -

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

Radio gear:
- Pioneer w/Micro Mag Switch
- iGyro SAT
- GPS-III
- PowerPak 5.0X2 (PowerBox batteries)
- SparkSwitch Pro
- PowerPak 2.5X2 (Ignition battery)
- PBR-26D Receivers (2)

Servos (ailerons-2, flaps, elevators)
- Hitec D950TW (8)

Servo (rudder)
- Hitec D951TW (2)

Servo (throttle)
-Hitec D955TW

Pilot Dude
- Extreme Flight X-35-40%- Red/White/Black

Servo extensions
- ElectroDynamics QuikClik

LED system
- UniLight PRO-Large Lighting Set

Mark, i had the 47% and I have the 32%. My initial thought is that you are a bit light on power. These are big heavy models. The builds are very straightforward, but as you know or will find out the manuals are almost useless.

Thanks...


Yikes!

Realize on the low end, but watching a few videos with DLE-111 and other similar engines spinning 27x10 - 26x12 props, I’m hopeful it’s gonna work.

Also I already have the Saito and ordered the model so fingers crossed!

Agree the manual is light on detail.

Thanks for your input - appreciate it!

hi, after doing so reading on the Saito i think you will be fine. you're up in the 6000s with a 27/10 which should be plenty. 40lbs is probably a bit optimistic, I'm thinking you will be closer to 50.

Decided to heed the thoughts and switch to DA120. Was hoping to use the new, big Saito FG-100TS but now share concern it’s both underpowered and weighs 4 lbs more than DA.

Thanks for the input, appreciate it!

Cheers
