The conrod is made extralight&superstrong alluminium to make the lightest and strongest possible conrod to withstand the abuse of a new .12 engine.
This is a special Tuned Crankshaft. Made to meet even the highest standards of our most demanding drivers. Slightly reduced rotational mass and greatly improved fuel flow provide great performance - extra light.
This Piston/Sleeve set is optimized for use in EFRA/IFMAR competition events and is made from hard chromed brass and features 3 transfer ports extra light material.
we have made this backplate with a special steel inlay, this reduces friction and wear when the conrod touches it. The round shape reduces the dead space inside the engine
Rear ball bearing:
The new ball bearing reduces the inertia of the rotating masses and increases the engine's scavenging. You can see both the ball bearing and the manufacturing process result in the picture. These novelties give an increased throttle response and a higer top speed.
