New from X-Act RC:
New from X-ACT is the Pro 5. If you thought the 3port Sportive was amazing this takes it to the next level.
The Pro 5 offers more of the easy tuning and reliability found in the Sportive by using the same high quality carburettor but enhances power using a new crankcase, 5 port piston and liner set with lightened piston for higher RPM, greater internal porting to enhance fuel flow and last but not least a coated crank. No other engine on the market we believe can offer all this at such an economical cost. We have worked hard to make this as much engine as possible for the money. Using advanced production techniques and modern machinery helps improve production tolerances and reduce cost.
To top it all off we have gone with a lightweight, drilled, CNC machined head as well and as standard the engine takes a turbo plug (we recommend a hot type plug)
All piston and liner sets are hand-matched and offer a tight initial fit but long life after the run in process.
Each X-ACT engine from the range is hand assembled here in the UK to ensure correct fitment, parts quality verification and the best possible experience.
Features:
- 5 Port ABC Piston and Liner for high power output.
- Coated crank
- Double bushed “PRO” Con Rod.
- Turbo head Button
- German manufactured O rings for long life.
- High quality 2 needle carburetor with thermal heat shield for consistent tuning
- Includes 8.00mm and 9.0mm carb venturi insert with alternative fitments available.
- Black treated crankcase with high quality bearings and laser etched logo.
- Multi fin CNC heat sink head for enhanced cooling.
- Pre shimmed for 25% nitro. Includes additional 0.1mm shim which can be used to ease running in or reduce shimming.
