Title: Super Tigre G21 35 Combat vs Stunt
Post by: William Fann on February 20, 2019, 11:59:57 AM

Is there any thing on the case that will indicate whether the 35 is a combat or stunt version?

It's not the carcass.

ST G21's were changed from combat to stunt by the cylindre y pistone' y capital.

The stunt setup can be identified by the baffled piston and slit head.  The cylinder porting is MUCH smaller on the stunt.

In my experience, there are no case markings.  You look at the piston.  If it has a baffle, that's the stunt version.  Myself, I always preferred the combat version.

Peter,  Why did you prefer the combat over the stunt?

Peer pressure and technical specs from Super Tigre.

The pistons, cylinders, rods and heads of the C & G21 series were interchangeable.

So you could put together a stunt or combat version with or without bearings.  The CRC setup was the winning engine for Profile Carrier.

The baffled (stunt) setup had far less power than the combat (flat top).

But when you wore out all the combat piston & sleeves you could set it back to stunt for something to do with the leftover parts.
