Start Here: Choose the Right Power & Gyro System
Use this quick guide to choose the right Booma RC power and gyro system for your aircraft. Follow the steps in order, then jump to the recommendation that matches your setup.
Step 1: Choose your aircraft size
Select the option that best matches your model:
Step 2: Count your servos
As a rule of thumb:
- Smaller gas/EDF models: 6–7 servos
- Mid‑size aerobatic: 8–12 servos
- Giant scale / turbines: 12+ servos, often on dual surfaces
If you are unsure, count every servo in the aircraft (including throttle, retracts, brakes, doors, etc.) and then choose the tier below that best matches both your engine size and servo count.
Step 3: Choose your redundancy level
For high‑value models, we strongly recommend dual‑battery redundancy. Use this as a simple guide:
- Single battery OK: Small 20–35cc, 6–7 servos, sport flying.
- Dual battery recommended: 40–70cc, heavier models, more servos.
- Full power distribution + dual battery mandatory: 70cc+ giants and turbines.
Step 4: Our recommended setup for you
Find the section below that matches your aircraft and follow the recommendation.
Tier A: 20–35cc aircraft (6–7 servos)
Typical models: 20–35cc aerobatic aircraft, small gas warbirds, EDFs and similar size aircraft with around 6–7 servos.
Recommended power, batteries & ignition
Option A – Simple, budget‑friendly:
- Single receiver battery:
- IBEC Ignition Kill Switch for ignition power and kill
Ideal if you want a clean installation with ignition kill and a compact power setup in a smaller model.
Option B – Entry‑level redundancy (recommended for most 20–35cc):
- Wallaby Switch Dual (dual‑battery sharing with voltage monitoring)
- Two receiver batteries:
- IBEC Ignition Kill Switch for ignition power and kill
Tier A bundles:
- Tier A Power Pack (20–35cc) – simple power solution for smaller gas models.
- Tier A Redundant Power Pack (20–35cc) – adds dual-battery redundancy for extra safety.
Tier B: 40–70cc aircraft
Typical models: 40–70cc aerobatic aircraft, larger warbirds and jets with higher current draw and more servos.
Recommended power, redundancy & gyro options
- Dual receiver batteries:
- Higher‑current power switch:
- Optional upgrade batteries:
- 3K Smart Battery (upgrade option)
- IBEC Ignition Kill Switch for gas engines
Want to add a gyro?
Add Smooth Flite SF10 Pro for advanced gyro stabilisation with Automatic Gain Control and clean wiring.
Tier B bundles:
- Tier B Power Pack (40–70cc) – high-current dual-battery power system for larger aerobatic and warbird models.
- Tier B Power & Gyro Pack (40–70cc) – includes power system plus SF10 Pro gyro for stabilisation.
Tier C: 70cc+ giants & turbine models
Typical models: 70cc+ IMAC/3D aircraft, 4–5m giant scale, and turbine jets where reliability and clean installations are critical.
Recommended full system
- Full power distribution:
- Smooth Flite SF20 Pro (full power distribution + gyro)
- or Extreme Pro (full power distribution, non‑gyro)
- Dual Smart Batteries:
- 3K Smart Battery
- or 6K Smart Battery for higher capacity
- IBEC Ignition Kill Switch for gas engines, or turbine‑specific ECU power as required
Tier C bundles:
- Tier C Power & Gyro Pack (Giants & Turbines) – SF20 Pro with dual Smart Batteries for full power distribution and stabilisation.
- Tier C Power Pack (Giants & Turbines, non‑gyro) – Extreme Pro with dual Smart Batteries if you already have a preferred gyro.
Not sure which tier you are?
If you are unsure which setup is right for your aircraft, send us:
- Engine type and size (e.g. 30cc gas, 120N turbine)
- Total servo count
- Battery type and voltage you plan to use
We will recommend a power and gyro system based on engineering best practice for your model, not just the most expensive option.
