Os Fs-90 & Fs-70s Help

[tigerstrike]

Hi, have a chance to buy two engines, both have been used, run perfect and are in super condition, have original boxes and instructions.

What should I pay for them????

Thanx

50% to 65% of the new price. (depending on the usage they've had)

Tiger,

Be aware, the OS .90fs is not a Surpass engine, its and older one and has less power than the .91 series. I've seen them go for 100.00 or so on ebay, FYI. I don't think the .70 was ever made pre-Surpass, so the 50-65 rule would seem more appropriate there:D

Later,
David

Thanx for the info, the 90 was an older model and the 70 was a 1996 model.

Congratulations - two good engines.

I have the 70 and it's the most reliable and consistent motor I have.

You'll really enjoy using it. You can use a very wide range of props and I've found hand starting no problem at all on any of them.

Once set up, it doesn't need adjusting despite many hours of flying. Avoid being a 'needle twiddler'; back off the fuel from absolutely flatout and you will have no trouble.
