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 $1925.00
Supersonic Mufflers (pair) $210
30mm headers available in 2", 3" and 4"
Headers, canisters and tuned pipes available. Check under accessories in the menu


Tired of hand cranking your high compression ZDZ 210 engine?

An electric starter can be installed onto your existing or new ZDZ 210 engine! The bottom mounted centrally located starter motor allows use of headers or JMB bolt on mufflers with clearance to spare! Starter ring diameter is 175mm (6.88”). Total weight added, 3lb 2oz…..bare weight with starter installed, 13.0lbs! Requires 24 Volts. (see pics at left)

Electric starters are also available for other ZDZ engines.

Please call for more information, pricing and delivery timeframes.

 

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!
