| As a newbie I never tried a heli stand as I to thought it was unsafe.
I decided to learn the safe way
Have an experienced modeler look it over first
you can't tune an engine on a stand because the load won't be the same
you can check gyro direction in a preflight
you can check for leaks by pressurizing the fuel system
My tracking has always been bang on during set-up
If you think you need a heli stand chances are you need to learn more
|
We seem to have lots of so called Experts here (arm chair pilots).

"Safe" in who's books? Yours? What is the "safe" way???? LOL

This tells me that you are just guessing and running with the "crowd".
You can run in an engine under better "controlled" conditions and you certainly can tune the engine from idle to midrange. But you might have to re-tune/fine-tune the midrange again , once you have tuned in the top end during flying.

Yes, and you can also make double sure that your direction is correct by giving s small amount of left or right as the tail will move a little bit.
It's obvious that you are just "guessing".

And you can't do that as a double check on a tied down base???

The final proof that you talk out of your rear.
It shows that you have very limited experience. Spatially the bigger birds running 690 ~ 710mm blades are prone to require fine tuning the tracking, no matter how careful your bench adjustment was. Very few helies have absolutely "zero" play throughout the control system and even that varies from model to model of the same Manufacturer.
Although the flybarless onces comes closest to the perfect condition, due to their more direct linkage system. (I am just setting up my first one now).
Now add any differences between two blades and yes..you still get them despite CF technology and top level manufacturing, and your "perfect" tracking from first spool up is pure luck.

Another one of those wildly thrown out statements.
Nobody "needs" anything.
You don't "need" a pitch gauge..but it does make life easier.
You don't "need" a governor, Tacho, Temperature Gun and/or sensor, 2.4G radio.........
Anyway..it was fun
Just too many "so called Experts" here with "zero" real life experience on the subject, to make this a worthwhile discussion. |

. If he can actually fines somebody that will pay that much money for one he should get into Real Estate.
