Re: [Titanaircraft] Re: Jabiru 3300 on a Titan 1

As soon as I have a reasonable excuse (read: money) to get rid of my Jab 2200 on my Titan I, I'm gonna put a 3300 on it. I love my current setup and it's the most fun I've ever had with my clothes on, but, an extra 40 horses and a different prop... ahhh, what a rush!

ah, now we're talking. That would be an interesting compliment to JD's SS concept, where the plane is like his Chevelle SS. The Shelby Titan or Titan SB or ?

Maybe also an aerobatically stressed version, where you have as an option fitting a snomo 2-stroke conversion like the rotax 670 for max power/weight (and 50 hour TBO's ;))

But still, it would seem to me a single with 150 Vne kit and 2200 is still going to be pretty spectacular (and weigh less too)....

My thoughts have been to do a "Shelby" version of the Tornado single place. There is another airfoil I would like to use and of course that would require a new wing. A new tailboom and tail surfaces would be required. The Titanium main gear suggested by Kimberly would be a good choice as well.

Although I am still working full time at another job, I'm sure I could find time to build the parts over some weekends.

> Nah. You're turning a smaller diameter, lower-mass,direct- drive prop than the 912, so the torque on the mounts is no more than the 912S with a 6-inch larger diameter prop. Also, the six cylinders and direct drive are smoother than the thigh-revving 912-series, because the 912 gear box shortens and sharpens the power pulses returned to the mounts trying to turn the large smooth rotating inertial mass of the prop, particularly at lower RPM. We've been flying our 3300 2S since 2003. It is the right engine for the job for as heavy as we load the plane and the altitudes we fly it, and it is especially well-suited for the 2SS. I've flown many Titans with a variety of power plants, including jumping between the 912's and Jabirus for concurrent flights, and you can feel the difference in vibration.

It would also need a 150VNE wing and wing mounts, and you'd want .090 windows so they don't push in or oil-can in flight. While the 3300 on the single place Tornado would be an absolute ball to fly at greater than 2000 FPM climb, it would also push it beyond the 150 VNE if not careful.

It reminded me of my old 5.0 mustang, with this big ol 302 shoehorned into that little bitty little car. It almost looked like the motor would twist off the frame soon as he advanced the throttle for takeoff.
