FAI Version

Non FAI Version

I noticed the same thing when I got my GRRT FAI. Our hobby shop had ordered both so we could look at them and see the difference.

The only reason I went ahead and got the FAI is because the exhaust was round and the pipe clipped directly on. The non needed a round adapter for it. I like the direct clip on because seems it would have a better flow of the exhaust and the exit exhaust port on case looked much larger.

I never tried the other non FAI to compare but seems the FAI had a better set up to me.

They are entirely different engines all together...

The FAI is designed to reach that 2.7 hp without nitro, just standard 80% methanol - 20% ricinus oil fuel...

And if I remember correctly (I'm not entirely sure) the Formula 1 guys over in the States use massive amounts of nitro in their fuel...

Default Grrt's

It's real simple!

3065 is the old model.
3070N is the new model.

There is also a 3070F available which is a front intake model, basically a nelson clone.

All of these engines are designed for FAI pylon use which specifies FAI fuel, i.e. 80% Methanol and 20% CASTOR oil.

The morris website is misleading in saying that the 3065 is designed for open class Formula 1 racing, which it isn't. (The Formula 1 racing class does not exist any more)

The Malina brothers did use this engine in their 1985 World Championship model, however, it was the FAI pylon world championship.

Yes...

You're right DerFly...

The old model would make a great low budget fast engine though.. maybe not as longlasting or maybe a bit less powerful, but still great value at that price I think...
