ZDZ is in the Czech Republic and it has been in business for many years. It was started by RC pilots who couldn't obtain engines from the West. These engines were designed specifically for the RC market, they are not conversion products. We offer two of the products that ZDZ offers because these two sizes are the best in the industry at this time.

The ZDZ-80 RV-J is a redesign of the older version. It starts great, runs great, and has power rivaling most 100cc engines. In many 100cc version planes, the ZDZ-80 RV-J will make the plane outperform the same plane with a twin due to the lower weight. Not only is the engine lighter, but there is only one exhaust. Not only same weight but save money! You will save $500 over a 100cc twin taking into account the cost of canister mufflers. I used it in my Aviation Models 35% (100cc) Extra 260 and performance was out of sight!

The ZDZ-210 is the best 200cc class motor at this time. I used it in my Aviation Models 40% Yak. It starts easily, runs flawlessly, and has power to pull around 55 pound planes. It is much better than other brands at this time.

Warranty: The engines are warranted by R/C Showcase in the US. The  ZDZ Engine warranty is 42 months, ignitions are 24 months and carbs. are 12 months.
