The burst rating. Continuous is... exactly what it sounds like. The battery's ability to deliver that current without stopping. Burst is a short term limit, although what exactly constitutes "short term" isn't standard, as far as I know. Anyway, As stall current isn't something that is going to be drawn by your motors for very long, you can generally compare burst rating to stall current.

If you're looking at the burst value vs stall current make sure you add 20% to your requirements for safety. If your batteries constant C rating is greater than or equao to what is required to moved stalled motors you dont need that.

Captain Xavier has done both of these in his "Can it take a K-26?" Series.

Need more info on cage. Otherwise try bigger flywheels.

Cyclones are the cats pajamas. I reccomend them highly. Otherwise worker high crush should do the trick. Im don't use canted cages but I'm pretty sure the concavity on worker wheels won't be an issue.

Just bite the dart and cut down the tabs. You wont regret it. You can always use anything as a shim to keep the stock motors in place or even the fangs if you remove too much material. I hope you saved the rubber big and tall "8" shaped pieces. Those hold the motors on in a stock cage instead of screws.

Also you can get a 10 dollar acrylic cafe from OOD by worker. Havnt used one yet but I don't think you would need anything else if you got that option. Keep in mind they come canted and in two different crush sizes. I would recommend the non-canted 42.5. The extra crush is fine for revamped motors. They will actually be happier with it.

 
There is also another downside to consider. Removing mass from the flywheels reduces their momentum, meaning the flywheels will have less energy to transfer to the darts, and slow down more between shots. In a stock blaster, it isn't the torque of the motors that pulls the darts through the flywheel cage and flings it out, it's mostly the energy stored in the rotational inertia of the flywheels.  The motor's job is simply to bring the flywheels up to speed.  Less mass  means less momentum, less energy available to impart to the dart, and ultimately lower FPS.
 
 
Generally, you only see vented flywheels in blasters with upgraded motors and better batteries.

Yes but more mass on the outside of the spin increases torque through centrifugal(or the other one) force wich might make up for the loss of mass on stock wheels. Arent instanto (sp?) Wheels lighter than stock?

Upgraded motors are probably a must but get a pair of artifact wheels and use them as a template to make the new holes. You might ruin them though if you make a mistake.
