I hope you guys find this as interesting as I did.

My Dr.I is my test bed where I ultimately plan to use this device to record flight parameters: Levil BOM I've wanted to do this since Rise of Flight came out over 10 years ago! Finally, I am on the brink of accomplishing this. I have to be successful on my own before I can ask someone (perhaps PJ) to allow me to study their aircraft using the same methods. I am in the home stretch of fabrication for the Dr.I prior to flight I have ambitions to fly it before the end of October, but sometimes life has other plans. I am going to Rhinebeck Aerodrome this weekend to learn from their expertise and hopefully build some good relationships that would afford me the opportunity to use the BOM on their aircraft in the future.

The average resting G tolerance for people is about 3.5 Gs. That is just sitting in a chair, no G strain exercise or anything to counter them. For me personally, I have to start doing anti-G strain at 4-5 to keep 100% vision. I've heard of guys (VERY rare) who have a resting tolerance of 6 Gs! Below 5 Gs, I can fight all day, but it is tiring. After a 4-5 G fight, it would probably be challenging to go hammer away at 7 Gs or more. Regarding small radius maneuvers, at these low airspeeds, the maneuvers look very tight! One of my friends watched me looping the DrI and said it was the smallest loop he'd ever seen (this coming from an aerobatic pilot) and I never hit more than 2.5 G doing it. The WWI planes just cant sustain G forces long enough for G forces to be significant. I imagine if you black yourself out in the Camel, it is a pretty short duration? I have yet to try it myself, but I will.

G tolerance on a WWI plane doesn't even need to be modeled. These planes can barely sustain 2 5 Gs.

To see a single WWI plane at low altitude at 2-3 miles would be realistic. To see a formation at 3-8 miles would also be realistic. The longer distance corresponding to larger formations. At high altitudes, you might get 30% improvement.

On these types of engines, yes. When the throttle body is opened all the way (full throttle) that is the maximum amount of air it can put in the cylinder. I asked some friends and it would be possible to over heat a water cooled engine in very hot climates. A rotary would probably not be as susceptible.

One of the guys there in the video has done it for his own Dr1 completely on his own! However, 1 or 2 other people helping is a more comfortable way to run it.

haha, one cannot simply go half zebra...it must be done ALL the way Here is a little more Fokker fodder for you

I am not an expert on these engines yet, but I am officially on the learning curve now!

It will run by the end of the month!

@LesG I should have said it this way (I will go edit the post in order to reduce confusion for anyone who reads this later): each aileron is controlled by it's own independent circuit. On aileron or its controls can be shot away, and the other will still work. The ROF/FC 3D model of the wires coming from the control stick is inaccurate. There should be two wires coming from the stick. Here is a picture of how it should be: The replica you posted appears to be a Sands plans airplane. Some of the details I can see in the picture are inaccurate (normal if you build it strictly according to those blueprints), so I will be surprized if the aileron system is accurate.

@Cynic_Al the metal plate in beneath the pedals is diamond plate, so it is tough with plenty of friction. I don’t know if that is exactly how it was originally or why they put anything there at all. If it was to prevent wear, it is a pretty ambitious goal to have the plane last long enough during the war for wear to be a concern. When taxiing on on the ground, that is the most my feet move on the pedals/floor. In flight, I can get away with simply rocking my feet on their heels to have adequate control for basic flying. Some “extreme” maneuvers require me to move my whole foot, but it isn’t too often. When I have it flying again, I’ll try to get a video of the cockpit so you can see what goes in to controlling it.

@LesG The 3D animation is inaccurate. 2 wires came from the control stick. Each aileron ("wing rudders") was controled by a completely independent wiring circuit so that one could be shot away. Hope that helps!

This has been a long road! Finally starting to see light at the end of the tunnel.

I am nearing completion of the cockpit mods required for running the rotary. Most recently, I installed the fuel and along with the necessary fueltank and oil connections to the engine. For your viewing pleasure...
