Status: offline 		dear sir,

1.wonder if you have personal preference for 2 or 4 stroke engines for
pattern flying. i understand that some people use 2 stroke like the OS1.4 rx because
of lower vibration and more power. i am referring just to pattern flying.

2. my second question is directed to a 90 size pattern plane i have. i am thinking
of using an OS 90 2 stroke on this but am concerned about excessive noise,
what are the ways to mute the engine without affecting performance?



please share with us your views.

The fastest way to reduce noise it through 3 methods. First, an effective pipe arrangement. There are many at Central Hobbies. Second, a soft mount. Nothing compares to the Hyde mount for efficiency. Third, go to a multi blade prop.

Best of luck,
Don

Status: offline 		thanks so much, mr don szczur, putting money aside. i presume the choice is obviously 4 stroke then.
how do you tackle the problem of vibration caused to the servos? besides the hyde mount, do you have
additional damping for the servos? what are the precautions you would take to arrest vibrations?



i always come across the term "hyde mount" is this a prototype name or is it specifically the one and only
hyde mount presumably sold by hyde? MK has their own kind of hyde mounts if i am not wrong.

thanks for your patience.

good luck and all the best to you too!!!

Best regards,
Don
