So I couldn't find a servo slower, though I did not look at very many places. Due to the extreme cold the other week my bearings got lost in transit. Hopefully the new ones will show up today. I think I got the preload set up for my tapered roller hub. The bearings are heavier so I will be right at the limit for weight. I made an upper A frame out of 7075 to try and prevent some bending and bowing. I also made a set of taller wheels that I may use if the floor gets too beat up. Unfortunatly there is too much snow to do some test driving as I would like to dial in my controls a bit more instead of driving in lines in my basement. The wiring was changed to all xt90 connectors exept for the deans on the drive motors. This will greatly speed up weapon motor swaps if need be.

That is flat out nasty!

That looks like it could be useful, I'll have to get one ordered for some more testing.

I am just going to use the esc like a contactor as my cheap pistol grip transmitter can only do that. It would be nice to ramp up the speed. I know there are a few different options of what I could do, but this late in the game I am not going to change anything else.
The new teeth should be fine and there is a little extra meat by the lone bolt hole as well.

So I haven't had time to figure out how to pull video clips off of youtube and go through my fights yet, maybe after moto... Anyway I have been doing some current testing with my different weapon bars and their effect on my weapon motors. I discovered that with my impactor bar after two spin-ups the pully and belt would warm up and not slip anymore. So cold it would draw 100 to 115 amps and warmed up it got up to 150 amps. I have done some testing with a ragebridge2 using current limiting and the results are looking good. I did 10 spin-ups and had the bar spun up for over 3 minutes and the motor was pretty warm but it should be ok. This setup will also simplify my wiring and be slightly lighter than the contactor setup. I also got my impactors back from the heat treaters and they came in at 54rc. Hopefully these don't break too soon as they took about 3hrs a piece to make. I also got 8 wheels cut out today. So far things are on track and I have actually had some time to do some testing.                                                                                                                                                                                                                                                                                                                                                                                         .

If I remember correctly when I was talking to pete at avc he was still running the vesc, but he had troubles with a certain branfmd. The build is looking good. Thanks for taking the time to post everything.

I was a bit dissapointed triggo wasn't there last year and I am glad you are making a new one! I am planning on getting there on friday again to help set up.

 Nice write up and good job at the event. I am running that same radio and it has worked well for me so far.

AVC was a good time! I met some great people there and the competion was fierce! BEAM held up quite well structurally, but I fried a few weapon motors. I have some more improvements to make to get it dialed in. When I go through the videos I will do a few recaps of what happened.

Ready to go for avc! Still a few things that I would have liked to do, but not enough time for this go around.
Hmm I cant seem to add any pictures

Alright time to get busy. I registered for avc in september and am in the process of buying a house that currently has no garage. So now I have got to get all of my milling done before it goes into storage. I got all of the side pieces milled to height. The front plates are also going to be the motor mounts. This will save some weight and make replacing motors much faster. I am making doubles of everything in anticipation for motorama as well because I probably won't have much spare time come the end of June.

There will be boring and tapping of the titanium. A guy I work with has a big lathe and used to make r/c car parts out of titanium. He will help me out so that is a bit of a relief.
I probably will get a shorter, thicker bar cut out for the vertical spinners. I wanted ar500 but the places that I got quotes from said they couldn't get it.

Got the gearboxes apart and the screws were loose. I was just wondering if the motors fit a little tighter in the regular 775 plates.
I was also surprised how the bar bent and everything else didn't explode. I ordered a small chunk of titanium to make a new weapon shaft as the aluminum one did bend slightly. Hopefully I can make it work.
