The very first model was the SR which was their first Schneurle ported engine but it had a rear induction drum valve (it was a pylon Racing engine) so R could be either Rear or Racing. Then they used the same crankcase but used a Front induction crankshaft.

Status: offline 		F front intake
S side exhaust
R ?? probably design/application type

MVVS uses the same, but with fuel as first digit so
Gfs/r means
glow (gas = I for Ignition)
front intake
side or rear exhaust (rotate cylinder)
GRR means glow, rear intake, rear exhaust

They were the later disc valve engines.

Status: offline 		Pe Reivers :I have a new in the box Evolution 26 GT and a new in the box Evolution 26GT2 and I plan to install them on a KMP Tigercat. MY questions are, will mixing the two generation 26's present a reliability problem? What would be involved in up grading The 26GT to 26GT2?

If you plan to fly 3D with the engine, it is wise to put an extra shim under the head ( unless you live at higher altitudes), and keep rev's up by avoiding the high load props 18x8 and upwards.
