Default jett powered, but a bit off topic....

Thought a few of the Revvers here might enjoy some refreshing craftsmanship.

Many of you are familiar with the Jett 90L and 90LX engines. Here is the same engine..... just re-designed a bit.

Rolls Royce (Ro-Jett 90) powered Spitfire. 14" custom made 4 blade carbon prop. Runs around 7000-7500 rpm

Not a Spit fan? How about a Ferrari ?

This post probably belongs in the extreme slow forum probably, but enjoy anyway

Builder: Windy Urtnowski one of the best CL builder/flyers/craftsmen of all time.

Enjoy!

What is the red plane and is it possible to get a real good shot of the tail? I want to look at the rudder hinge line and linkage. Top secret project.[8D]

some of the better stunt ships have hinged rudders - adjustment and trip capability.

I have seen a two examples that have in-flight adjustment on the rudder (automatic) to keep line tension, but that was on sport scale not really stunt birds.

In control line stunt it is known as the "Al Rabe rudder". The rudder can be adjusted to remove all of the prop gyroscopic precession from the propeller for inside and outside manouvers.

I would guess that 99% of all RC fliers don't use the rudder when doing loops, but you will find that when you do the airplane tracks better. Most noticeable on draggy airplanes with big props.

I say if it's Jett powered and cool in any way, I want to see it - slow or no! Why not post it here, you have loads of Jett fans that might not lurk anywhere else you may post it - me included.

IMHO CL stunt models are the epitomy of the art and science of model finishing, alongside precision scale but without the artistic constraints.

And they don't fly none too poorly either..
