Prop For O.S. .46?
Hi I just recently recieved a diamond dust kit for Christmas and am really enjoying building it I have two questions.
I am going to put an O.S. .46 with a moosecan pipe the engine was broken in on a trainer and most of its life was a on a trainer will that affect the performance of the engine since it was originally broken in on a trainer? What prop should I use? |
RE: Prop For O.S. .46?
If it is an FX I would use a 9x7.

RE: Prop For O.S. .46?
Being broke in on a "trainer" won't affect the engine. How the engine was broke in.....i.e. "needle settings", has everything to do with how the engine runs. If the engine was ran rich, then all is good. If it was ran lean, you might have premature engine failure. It really depends on what 46 you have, for what props you use. Myself, I like to use 10x4, 10x6, or 11x7. It's like most anything else, it's personal preference. Hope my two cents helps. Happy Flying, Joe

Hi, could you give me a web site where I can buy a diamond dust kit? What is a price of it?
I am flying a diamond dust with an Evolution .45 power sistem with Rossi tuned pipe, 5 % nitro fuel and APC 9 X 7 prop. It flies well but I need more speed. Evolution is not enough for extreme speed and OS .46 AX or FX are similar to evolution engines. Gabriel, from Argentina. |

first few flights 10x6 APC just to get some flying time in.
9x7 once you are comfortable with the DD. |

Happy Flying, Joe And to repeat what was suggested - if you had to pick one prop, go with the 9-7. If the engine is in question a few short high speed runs on the bench - 9-6 good choice, rich but fast 2-cycle (i.e. safely short of peak, use a tach if ya got one), with cool down periods between, never hurts. You'll find out what shape it is in pretty quick, better there than on an airplane. MJD |
RE: Prop For O.S. .46?
I agree a 9x6, 9x7 prop is a good choice for the DD, but it sounds like this is a second airplane. Crashing is NO FUN! If you went with a prop that "slowed" down both the engine and airspeed, their might be something left and the end of the flight. That's where my prop might be usefull. Like I said before "all to their own". The DD is a fast airframe, and might be a handfull???

Thank you for all of your responses the engine is an O.S. .46 Fx The website where you purchase the planes is http://www.diamonddustrc.com/ and they cost $74.95 they kits are very good (I think I've only had 1 piece of bad material in the entire kit) the manual is excelent.

Either way sounds like Flyingman03 is having a good time building. That's what it's all about! The 46 FX is a great motor, and very forgiving nomatter what prop choice.
MJD.....I like your "Irish" saying |
