Nitro engine ZR.28 Spec.4 Pullstart

Nitro engine ZR.28 Spec.4 Pullstart

With the LRP ZR.28 Spec.4 Pullstart a significant improvement of the carburetor fine tuning as well as the cooling of the cylinder head could be achieved by modifications of the excellent base of the predecessor model. The Heavy-Duty CoolDownMax cylinder head, which is already successfully used on the larger models, is now also used on the 28er.

A completely redesigned carburetor has been installed for even better adjustability, especially at idle. The running behavior at a standstill is thus significantly optimized. All in all, the ZR.28 Spec.4 Pullstart has more torque with better adjustability and improved response.

Otherwise one of the big ones, it shows itself to be a pipsqueak in terms of dimensions. Due to the compact design, the engine can be used in direct replacement to .21 engines. It fits in all common .21 motor mounts.
