28X 10 PROPELLER

[skymaster68]

Hi tomorrow is the maiden for my 34% CA MODELS Extra 330.
It has a DA 100 that has about 8 galons thru it.
My cuestion is what about a 28x10 biela prop? how is it compared to a Mezklik?
I all ready have the Biela and woul like to know your opinion.
I fly IMA and some 3D

The Mejz 28X10 is a wierd prop, in that it doesn't load the engine up as much as most other 28X10's, yet has some friggin' serious pull. Try the Biela, but I suggest you get your hands on the Mejzlik, too. You can never have enough props - my 260 only has about 20 flights on it and I have already flown it with a BME, NX, Menz, and a Mejzlik. So far, the Mejzlik 27X10 has the least load and is quite, but not a stump puller at my elevation. I now have a PT 27X10 that I will try this weekend.
In aerobatic setup, the prop is the first thing in the fine-tuning process, so it doesn't hurt to experiment.

I dont think you will like the biela on the DA, its a lot of prop, unless your airplane is really light. I would suggest a PT 28x10 or one of the Vess 27s for the DA. My 3w 106 had more power than my DA 100s, and I still didnt like the biela 28x10 on the 3W. The PT Props are awesome.

My field is at 1550 ft

you can always try the biela, but if you cant spin it 6000rpm or higher, I dont think you will like it.

Yeah, what he said. At 1500 feet, the DA can turn a Mejzlik 28X10 at around 6500. If you aren't within a couple hundred R's of that with the Biela, then it probably won't be the best prop choice for 3D - probably an option for IMAC, though.
