DIY For Life!

Hello Members,
                    I am going to show how to make a very cheap prop adapter to fit a GWS 4025 prop...

Take a 2mm bicycle spoke nipple,

Select a drill bit acc. to your motor shaft size(for a tight fit I selected 2.2mm bit for 2.305mm motor shaft),

Drill it exactly half down its axis,

Check proper fitting by test fitting it by hammering with a light tool like a plier/screwdriver or any other tool that is available...

Once fitting satisfactorily, place it inside prop bore according to your choice of side,

Put a drop of C.A. Glue(FeviKwik or any other equivalent) taking care not to drop C.A. inside the nipple,

Fit the prop on the motor and test...

Heres the motor with which I got best performance...a 25000 RPM 12 volt Johnson Motor.....Kindly let me know any other motor which works well with this prop...

Tachometer reads 16000 RPM+ at 12 volts and motor draws 2 amps...

Alok, its a GWS EP 5030 prop.. the gap between motor shaft and prop is eliminated by a simple metal shim with nurling.. done by tiny coping saw.. and glued.. works fine..  Thumbs Up

Last month I didn't have a prop for the DT700 in my Phoenix Magic. Looked through my old stuff and found a Zinger 10x5 (wood). Its hole was too large. Solution?

Add heat shrink tube to the shaft and shrink it. Add more till it matches the bore in the prop. No need for hardware.
