ZDZ® Giant Scale Gas Engines are proudly made in the Czech Republic by ZDZ® Modelmotor s.r.a.. These engines are designed from scratch for RC Model Aircraft. No industrial engine or chain saw parts are used. Many years ago the ZDZ® ModelMotor engineering staff was given the daunting task of designing a family of gas fueled model airplane engines that must meet many conflicting specifications: Lightweight, Powerful, Low vibration levels in the single cylinder engines, Fuel efficient, Reliable, Long lived and easy to manufacture . They succeeded!

ZDZ engines have rotary valves*. This is one of the main reasons for the incredible throttle response of ZDZ RC gas engines. Most engineering experts agree that the rotary valve has brought the two-cycle engine its highest degree of efficiency and performance.

*ZDZ 80 R2, 100 R2 and 420 B4 have reed valves

Engine with Electronic Ignition $1450.00
Bolt on muffler pair $155.00
3" and 4" 25mm drop headers, JMB Silencers and AMT Tuned Pipes also available

 

Recommended Starting Procedure
for ZDZ Engines

 All ZDZ engines that use a rotary valve with fixed induction timing must use a unique starting procedure as compared to their piston ported or reed valve inducted counterparts.

 The starting procedure described below is most commonly referred to as the “5, 5 and 1” method. It is the preferred way to start a ZDZ engine once the carb has been primed.
For brand new engines, a richer low speed needle setting of approx. 2-1/2 turns out is required for initial fuel draw.

Step 1
 With the Choke completely closed and the Ignition system OFF, advance the throttle to full open, Flip the prop smartly 5 times.

Step 2
 Open the Choke completely, Leave the ignition system in the OFF position, leave the throttle at full open, and flip the prop smartly 5 more times.

Step 3
 Reduce the throttle completely and advance the trim to a mid to high setting, turn the ignition system ON, 1 smart Flip and the engine will start!
