When I built a Hangar 9 DHC-2 Beaver, I wanted to add the realism of a Saito three-cylinder radial engine (saito-engines.info). This four-stroke motor not only produces a beautiful sound, but also has a cleaner and more economical fuel usage. The Saito Radial Engine requires new setups for the fuel tank system, throttle, and servo installations, as well as other options regarding exhaust systems. Let’s get down to business!
AIRFRAME MODIFICATION
Using a Dremel fitted with a cut off wheel, the engine is trimmed down to the required length for the Saito 33 engine.
The Saito 33 engine is temporarily attached to the firewall. Before final installation, I coated all wood surfaces with Zap finishing resin.
Reinforcement of critical areas is essential with square or triangular spruce. The firewall and engine compartment are two examples of components shown on the photo.
For strength, most giant-scale planes have an engine built into their fuselage. The Beaver follows this trend. You glue an assembled engine to its upper, lower and side frames.
