HAVE RECENTLY INHERITED A GIANT SCALE ENGINE WITH THE EXTERNAL MARKING OF "G4D" ON IT ONLY. IT HAS A PISTION DIA OF ABOUT 2" AND A STROKE ABOUT THE SAME SIZE. COMES WITH A COBRA ELECTRONIC IGNITION SYSTEM; A WALLBRO CARB & BENETT MUFFLER + 6 ALLENHEAD SCREW PROP MOUNT. WEIGHS APPRX 6.3 LB.
TORE OPEN THE BACK COVER OF THE IGNITION SYSTEM AND ON THE FLYWHEEL MAGNET FOUND THE MARKING "IKEDA 500 - 11000 RPM". PROBABLY REFERRING TO DESIGN CO. OF THE FLYWHEEL & IGNITION MODULE". HOPEFULLY WONDERING IF ANYONE OUT THERE IN FLYLAND COULD FILL ME IN ON THE POSSIBLE MANUFACTURER AND SPEC'S ON THE MOTOR. WOULD GREATLY APPRECIATE IT.

Post a few good photos.

I second the photo request. You will have quite a few guesing then.

Andre

Must be pretty excited about the engine to be yelling at everyone

Zenoah Red Max conversion..Chaninsaw or blower....

I am not yelling and yes i am really excited about it!!
By the way thanks for the ABSOLUTELLY RELEVANT INFORMATION TIRED OLD MAN!!!

I don't think TOM was talking about you at all. He was probably talking about rcmod. When someone posts using all caps it is considered bad form and is known as yelling.

If so my appologise for tired old man.[sm=confused.gif]
I've just learned something new.
Thank you Big_Bird[sm=thumbup.gif]

Thanks BB. Everyone uses the net but fail to understand protocols.

It's an old antique Zenoah conversion..41.5cc..Roush made stuff when quarter scale started...It's green on the back because it was probably a Green Machine brand industrial engine..
The bolt pattern on the front is the same still used for mounting the G45,62, and 80..The hex bolt on the bottom is the same as on the G38...
Ikeda still makes the G38 flywheels...
I can cross reference the carb if its a Walbro...
