What the ''lower cost'' products sorely lack is a decent mid range torque curve. This is where most fall down as pattern contenders. It will be interesting to see how the OS stacks up in this regard.
Steve,
The DLE55 on pipe is very nice runner. Very smooth and extremely quiet on my soft mount turning a 20x12 3 blade. I have the weight down low enough to make it useful in a pattern application. Currently flying the 78" EF Extra with it and at around 13 pounds all up weight it is no real load for the DLE.....but terrific fun.
I might actually make weight in a pattern plane but it would be tough. Not that that really matters much at local events anyway so the engine will go in my first new prototype plane.
That's why the 33GT is so attractive and if it gave me just a bit more mid range than the SAP 180 that I've been using, it would make a compelling argument for a 10 1/2 pound airplane. However, the rear exhaust headers are much more readily available and easier to install in a pattern plane than the return to center headers of side exhaust engines, so the PTE 36 has got my attention
