Same. In 2011 we tested all our 775s and at the time of installation they were good. Over the competition season, we developed case shorts, resulting in us lying dead during a large number of matches at GTR-W. Robot would start autonomous, and when the arm hit a certain angle, we'd cut out for about a minute.

2056 helped us troubleshoot the case short, and loaned us a "775 blaster cable" that allowed us to temporarily clear the short. It got us through the competition.

I wouldn't touch a 775 again unless the case is electrically isolated. Mounting to lexan, and plastic 1st stage gearing is a good start.

With the 6 CIM limit and 2 Mini/Bag-CIMs in addition to the AM 9015's, I really don't see a reason to ever use 775s again, period.

We've had good results with them in the past, maybe we're just getting lucky and getting "good" ones. We appreciate everyone's advice on the motors, however. You can never get too much info like that.

I think this might just be a case of we'll use them until they bite us in the butt, as we have yet to have problems with them the last 2 years.

Good luck to everyone this year, I look forward to seeing everybody's robots in the coming weeks.

Thanks for the advice all. We have already put in place electrical isolation with nylon standoffs and plastic transition gears. It's great having a SLS rapid proto printer sponsor!

so for those who are asking: either a strait or curved would work its really about the pressure on the Frisbee, how much they are compressed, and the psi in ur wheels (or 0 if you are using hard wheels)

Ours shoots far over 100ft at only a 10 degree angle (at 30 we hit the ceiling of the cafeteria) :rolleyes:

here's the video we have so far (we are getting a better one up soon):
