Overview

A stunning engine with solid performance and reliability – the 9 Cylinder 99cc 4-stroke glow radial engine is designed for larger models, specifically scale applications where the use of a radial engine in a round cowl will provide the ultimate scale look for the modeler’s plane. While providing great looks and sound, it also delivers the dependability and performance of Evolution.

UMS UT 9-99 is unique in appearance, successor to the very popular Radial Engine UMS UT 7-77 (of 77cc capacity). UT 9-99 astonishingly has very negligible vibration and sound. The ease of starting and fuel efficiency is a special feature.

The highest aero grade Aluminium is used, forged steel rocker arms, hand lapped valves are the specialty for this engine.

This 9 Cylinder Radial Engine is also a classical engine and a collectors item.

This image shows the installation of the 7-35 engine in a Seagull AT-6 1.20 ARF (SEA3550). This is with the cowl removed showing the installation of the collector ring and you can see the wiring for the on-board glow system as well. The 9-99 looks the same.
