Do you know how the performance changed when you put the BAG on it? Did its speed and/or force change?. If you had a model number for the original motor, that would be really helpful for comparison, since it doesn't seem to be listed anywhere.
Thanks.
EDIT: I just noticed that it (and all other similar models) are out of stock online. Did you order it online or (since you guys are in Canada) were you able to get it in a Princess Auto store?

I believe we were fortunate enough to just walk in and grab one. We measured the rpm of the stock motor to be 1000rpm (roughly) and I recall the subteam we have working on this saying the bag was 7 times more powerful (don't quote me on that one). However the 1000rpm is what we measured and the bag is 14000rpm. That turns the actuator into something that went 1/3in per second, to one that goes 4.6in per second now.
Also, although we think the force is around 7 times greater from the bag, I would not plan to load it much more than what its rated for (200lbs static load) as you might start having mechanical failures in the actuator.
