First gas engine
 

I just picked up a new old stock Sig 4 Star 60 ARF and would like to try a gas engine in it. I have zero expirence with gas model engines. Could some one point me in the right direction?
thanks,
Phil

The Evolution 15cc and the OS 15cc gas engines are a good choice for a 4 Star 60 or 64.

You should also look at the RCGF 15 beam mount, it's a more traditional design, it has a rear mount Walbro carb and is lighter and less expensive then the OS or Evo

Here is some information on the RCGF 15

Glow power isn't the only option anymore. The RCGF 15CC not only fills the displacement gap, but includes a beam mount to make the glow-to-gasoline
upgrade drop-in fast and easy. A rear pumper carb simplifies installation and adjustment.

The RCGF 15 would be an excellent power choice for your model. My buddy has a Hangar 9 Ultra Stick 60 with an RCGF 15 that hauls it around in a most impressive fashion.

I was considering the RCGF 15 for my Hangar 9 Katana s 50

Thanks for the help. Now to choose.

Yes I agree the RCGF 15 is a great little engine.Handles very nice and good power.I am flying one in a 82 span Road Runner. Friend has one in a Easy Stick from value hobbies.
Valley View sells them now.The new Valley View 40 twin is built by RCGF now.I have two of the original VV 40s. Never had a problem with either of them. I build my own ignitions.
