Ernie Misner -> Is there a listing anywhere of accurate engine weights??? (4/28/2008 8:58:21 PM)

Greetings, I'm without a good scale at the moment and am wondering what the real-life, approximate weight of an OS 55AX, Saito 82, and OS 70 Surpass, with mufflers. I do know that the 55AX is just over an ounce heavier than the 46 AX.

It's frustrating that the specs the manufacturers give are hard to go by. Perhaps there is a list of engine weights, like there is rpm figures, here somewhere at RCU?

Thanks,

Ernie

I've found the weights listed on OS's japanese web site to be accurate.

The quoted weights are for the engine without muffler, but there is a separate chart on the dimensions page that lists the weight of all the mufflers.

The .55AX is 404gm + 120gm = 524gm (18.5oz)
The FS .70 Surpass II is 580gm + 55gm = 635gm (22.4oz)

Hi Ernie, I have a top quality digital scale and I weighed a few of the engines you mentioned. Weights are with muffler, bolts and glow plug and are brand new never run engines.
OS 55 AX=18.2 ozs
Saito 82=18.0 ozs
OS46AX= 17.4 ozs

If you go to the RCU user reviews under specs the engine wieght is listed without muffler.
