If not tuned right, any motor will go through bearings. OS motors are a very good brand.

no not at all
the guy at the hobby shop said he knew more than the person tht owned the shop

Burned up 2 pistons in 2 gallons or less..... sry but he stinks at tuneing......all my motor's 5 gallons or more. have 1 with 7 to 8 gallons maybe more in it befor i retired it and it still ran.

I have seen guys that have been doing it for a long time that cant tune correctly. I saw a K-4.6 that the bearing retainer was melted out and the balls were laying in the crankcase, and he had been doing it a long time. A piston doesnt just go out, thats pilot error.
Not trying to be an ***, just telling it like it is. I worked at a LHS, and I saw it every day. Guys with 10+ years, burning up engines every day. And if you think a STS is better than an OS.....well, I wont go there lol.
yh but if anything went wrong with the sts i can by 2 for the price of 1 os

i remember when i was at scool, about 8-9 years ago, os had a brilliant rep for reliability, as far as i'm aware, that hasn't changed, so the sts would be false economy if it died ( i dunno what their reliability is like...)

its not about the cost of an engine, its the reliability and power. OS is a well name manufacteur and they dont have problamatic engines.. (spelling errors :P) So whoever goes threw 2 pistons with 2 gallons with a REAL OS theres something wrong with the tuning of it, not the engine.

i think i've said this before but i'll say it again. keith bontrager (mountainbike legend) has a phrase, it goes siummit like this, 'light, cheap, strong, pick two, it wont be the other one'
all u guys live i n the us
i dont
the weather is total different in the uk and this may effect the engine life

cambridge, England. os have a gr8 rep for reliability...

You tune for temp and humidity regardless of where you live.
what about rb
im mainly thinkin force 28 or sts 30
i heard he ran them on 25percent nitro and quite lean
but he likes spending money on engines
im thinking of os, rb and nova
thanks alot
