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.

NEW ZDZ ENGINE TECHNOLOGY!
ZDZ Modelmotor is proud to announce their collaboration with a major Italian manufacturer to provide new state of the art cylinders on all new ZDZ engines. This hi-tech Italian company also provides engine parts for motorbikes and automobiles and specializes in plating technology.
The new cylinders feature a new enhanced high strength aluminum alloy with a bead blasted finish for optimum cooling. A durable Nikasil plated cylinder liner is computer honed to an exacting tolerance providing a perfectly round barrel for improved lubrication, compression and of course, higher power output. They are also much less prone to scratching, peeling, overheating or seizure. This equates to a significant increase in engine longevity with a high level of sustained performance.
For those of you familiar with ZDZ engines and their reputation for extreme power to weight ratios with lightning fast throttle response afforded by rotary valve induction, this is great news!
ZDZ Modelmotor wants to be your only choice for innovative high quality European engines!

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!

WARNING - Gasoline and Turbine powered R/C model aircraft are not manufactured to withstand unlimited G's. Any R/C model aircraft can fail, be it a wing folding up or a fuselage breaking in half under too high of a load. Just as any full size aircraft, model R/C aircraft have a maximum G rating. Because you are not in the plane flying it and experiencing the G's and reading the G-meter, it is more difficult to judge the G's on the aircraft, and it is very easy to exceed the limits of the aircraft. Understand that if you perform a snap roll, parachute, wall, blender, knife edge loop, or pull hard on the elevator at almost any speed, you can be putting in excess of 15 G's, even in excess of 30 G's, and most aircraft can only designed to take 10-12 G's. If you perform any violent maneuver, you can break your plane. When I perform hard maneuvers, especially for the first time on an airframe, I am prepared for a failure and am prepared for it as best I can be. This mainly includes performing the maneuver far enough away from spectators that in event of a failure that I am not endangering others. In addition, be prepared for the manufacturer to not pay for a new airframe which is broken during flight. It is common practice for any manufacturer to not replace an airframe which breaks in the air or upon landing. I have only seen manufacturers replace airframes when they have received many of the same failures and the manufacturer determines that there was a design or manufacturing error. If you break an airframe, and you are the only one to do so, then it is probably not the fault of the manufacturer. Please fly safely, and avoid full throttle operation other than at low airspeeds.
R/C model jets, warbirds, aerobatic planes and UAV Unmanned Aerial Vehicles to name a few are
not a toy! If misused, it can cause serious bodily harm and property damage. Fly only in open areas, and AMA (Academy of Model Aeronautics) approved flying sites. Follow all manufacturer instructions included with your plane, radio, servo's, batteries and engine. Aircraft manufacturers guarantees each kit to be free from defects in both material and workmanship at the date of purchase. This warranty does not cover any component assembled by the customer. All parts of high stress must be inspected and reinforced if necessary by a competent builder. Some parts should be glued again. High stress areas such as firewalls, motor boxes, wing mounts, landing gear mounts, etc., are areas of high concern. Seek help if necessary. In not case shall TBM be liable for the cost of any product it offers which is not manufactured by TBM. The liability to the manufacturer cannot exceed the original cost of the purchased item. Further, TBM reserves the right to change or modify this warranty without notice. In that TBM has no control over the final assembly or materials used for final assembly, no liability shall be assumed nor accepted for any damage resulting from the use by the user of the final user-assembled product. By the act of using the user assembled product, the user accepts all resulting liability. The kit manufacturers have provided you with a top quality, thoroughly tested kit and instructions, but ultimately the quality and fly ability of your finished model depends on how you build it; therefore, we cannot in any way guarantee the performance of your completed model, and no representations are expressed or implied as to the performance or safety of your completed model.
