MODEL AIRPLANE P51 RACE PLANE
« on: April 09, 2013, 02:44:07 am »
This is a 1:4.5 scale model of the Galloping Ghost P51 Unlimited Racer. It is aluminum, fiberglass, Carbon Fiber, birch, and poplar plywood.

The engine is a multi cylinder four cycle engine made in Germany. This video is in SE Germany near the Austrian Border.

It  has extraordinary sound.

This first Video is just starting it up.

The second video is a fast fly by flight video. A good deal of the noise you hear is of the prop.

You guys that like to work on chainsaws would just love the Kolm four stroke engines.

This one is 235cc, four cylinder

The Mustang. This airplane, due to its high performance, would require considerable piloting skills for it pretty much has the performance of a turbine powered model airplane.

That part of South Eastern Germany with the farm fields looks like North Western, Ohio. Some of the videos with the ski slope hills were made in SW Austria.

I was flying my 10cc four stroke plane at the local airport and my friend had a 50cc Echo powered plane. Another local UAV pilot friend showed up with his UAV friend from Phoenix that had a 200cc four cylinder USA made two stroke engine in a 1/3 scale 3D plane. My immediate impression was that the runway we were using and the available free space wasn't large enough to safely fly this plane without being a threat to the full size planes and the local neighbors.

These USA made two strokes are the most popular engines used at the flying field behind cut4fun's house. The smaller ones are more popular like the 50 and 60cc singles and second are the smaller twins. I say US made but I think the cylinders and ignitions are sourced elsewhere.

I have seen the 1/4 scale and thought they were pretty big so 1/3 scale I can only imagine how large they are and how much room they do take to fly and land.

I still like the way that P-51 sounds when flying.    When making a flyby it sounds so much like the real deal of a full scale plane.

Very interesting.

A lot of the sound you are hearing with that P-51 is the prop and the fact that he is keeping the throttle full open on most of those passes.

As far as room needed for 1/3 scale, it depends somewhat on the plane and how the pilot flies. The flying field behind cut4fun's house is nowhere as big as the runway area at the local airport on the west side of the town where I live but at cut4fun's house there is no airport with full size planes flying close by and the closest house is 1/2 mile away. The runway at the model flying field is only 300' long but with over runs and clear back of the trees. It used to been a skeet shooting area and was timbered out around 10 years ago.
