Hi,
How do I remove the pinion gear from the motor without damaging both the pinion and the motor?

That pinion looks like Align TRex pinion. Look around the pinion to see got any set screw or not. If don't have, then u have use HZM method.

Thanks for the offer. I am thinking of using a soldering iron to heat up the gear and slowly tap out the gear. I think they might have loctite the gear to the shaft.

BTW
It not an Align motor. I just use the pic to illustrate.

The heat method won't work. The metal shaft & gear conducts heat too quickly. GWS sells gear remover. $14 to $18 depends on size. I got, PM me if u live near toa payoh.

Thanks. I am staying in Simei.
Couple of things I need to do before I pull out the pinion gear.
I nose dive the plane last weekend.
Stupid thing on my part. Change a new radio. Told myself to make sure I got all the control surfaces deflecting the right way. Check a few times, did range check and still didn't realise that the ailron is on reverse. Real stupid of me. Only after the crash then I notice.
Anyway smesh the step-down gear box. I have to get a new gearbox and if it uses the same gear pinion than all is cool else I'll PM you.

I will also strongly recommand using the proper tools bro...

removed a pinion gear once off my motor for ratio difference, using the 'cave-man' method. won't work, infact drop the whole motor away bcoz shaft was bend...
