If advancing the timing is what your after then yes. You can do it but like fly said....not really worth the effort. If it was a hi performance motor, and in a car, then yes. You could upgrade the motor for another brushed motor for pretty cheap. However if you want to try it out and it doesn;t work then your only out 6 bucks. Might be worth it to learn something new. I used to advance timing on my old race cars with 540 can motors back in the 80's. It is fun to tinker and learn if nothing else.

Did the re time to 12 deg advanced. ground test seems to have more rpm and more thrust, and the motor and battery stay cool. The old fish scale said about 4.5oz more. The radio and speed control are not the original, I have a 30A Turnigy esc and old futaba rx. Will do a flight test this Sunday. On the motor it self, there are three slots on the end of the case and a tab on the back plate. the tab was in the "0" position so I advanced it to the next slot.
The propeller I use is the GWS 10x8HD and with the motor in the "0" position, it seemed like I could not get enough RPM to make the prop work at it's full potential, now I think it will do better.

I am interested in knowing how this turns out.
Keep us informed.

Made a little more power! Flew it twice today and it did make a little more power, I can climb steeper and fly faster. I wish I had some test equipment to look at amp draw but I did get 3 or so minuets more flight time. That was the morning flight.
The second flight later in the afternoon was great until I landed on the roof of the gym. The wind started out around 10mph and there were a few clouds in the sky. You see here in Montana there is a saying "if you do not like the weather, wait five minuets". This holds true as about 10 minuets into my flight with lots of rolls and spins, the wind kicked up to about 25mph on the ground and I can only assume 35+ in the air. Lightning crashed and the clouds turned black , some rain fell and I convinced myself to pull into a wide turn and begin my approach into the wind. While crossing the wind the plane took off like a rocket with the wind. I fought with it and managed to turn back into the wind but made no headway. So having about 150ft under the wing I put it into a slight dive to make some headway. This worked well and everything looked great until I was almost blown off my feet by a nasty gust. Somehow the gust turned the wing around and took me into the gym at the high school where I fly I pulled up looping to inverted and blasted my ailerons to foll over, and then the gust died! Now in a stall having been blown backwards over the gym just about 5ft over the roof the wheels hit the skylight and that was the last thing I could see as the SC disappeared behind the roof line. Being part monkey I climbed onto the roof of the locker room and up a ladder to the roof and found the SC right side up in one big piece and a few very small pieces. Lost the landing gear skirt on one side and about 1" of the left wingtip. One of the wing struts was just pulled out of the mount at the wing and there is a small crack in the tip of one blade of my GWS HD1080 prop. The motor can backing was a little bent and the bushings were a little bound up but the prop still turned with some drag (I fixed that, works fine now). All in all not a bad crash, I planned on modifying the landing gear and the wing neways. I'll cut 2" off each end and round the edges. I'll let you all know how it goes any ideas?
Bye for now, I got work to do.

Sorry to hear about your crash. When I was a teen, my dad and I got into racing rc dune buggies - We had cars called "the Hornet" - they were budget racers that we modified to compete well with the Jrx2 and rc10. I can remember dad doing this to motors we used in our cars before we bought the expensive ones. That is neat that you did it on the stock sc motor. I might try it.
