Upate-

Have been running the truck lightly for a while, the rcm lipos are doing great! I couldn't ask for more...(or could I) The motor has yet to reach 125 degrees.

I replaced the ball ends on the truck with offset ends to match my 0 offset rims..trouble is that I neglected to make a note of the turnbuckle length, so now my truck has about 3 degrees of toe in instead of out . Also broke my wing mount and my my battery tray ends while running with Eovnu the past weekend.. The story to the battery trays goes as follows. I was just zipping up and down the street and Mike(eovnu) let his girlfriend drive his hyper 7- he told here to drive the car to him so he could check something, all was well and she decided to floor it in reverse.... headed strait for me.. I jumped to avoid the car while cranking my steering wheel to the right on my m8. The cen went flying into a curb at about 20mph... blew the front battery stops right out.




So I have a little bit of rebuilding to do. My time is limited as its FIRST Robotics "build season" where we work everyday after school till 6, then weekends 8-5.

Right now i was experimenting with our teams hand lathe, making a center spool for Mike's hyper seven.

If you have seen my other thread, you know that i have been having motor mount troubles. My 1/8"2x2 aluminum angle mount is starting to deteriorate and flexes ALOT!, I noticed it when I would yank the trigger the gear sound would change(loading up) then die back down once the truck stopped accelerating. The solution seems to be a 3/16th" 6061 aluminum mount off the center diff, tied into the main chassis. Im probably going to make that today.




Sorry for being long winded :)

Replacing the Arm as we speak, no spare wing mount though


More pics in a few.

You don't need a wing anyway...

wings are for squares.

New Rx/esc plate

[Metallover]

Did you attach the motor mount to that esc plate? You should.

No, it replaces the center plate that is usually there. no need to attach it to the motor mount.

Very nice.

Nice Ben, now wheres the turkey bar?

[eovnu87435ds]

thats karma for u ben

he decided to rape my hyper when it only had 3 wheel drive, and flipped it over, then drove over it multiple times... then he ran into a light pole abut a minute later and broke the arm! btw it wouldve been cooler if u put the rx under the mmm on the plate or put the plate at a 45 degree angle

Right now the switch for the MMM is on the underside of plate. I wouldnt put the rx down there in fear of wires coming into contact with the pinion/spur.
just hope it will fit under the new body..

you shoult connect the mount with the chassis, with a bracket:


like that you have
-no flex at all
-the chassis turns into a heatsink

its quickly done and it works. I have two mounts, one for a bigger motor (kb45xl), all alu in L-shape, and one made of alu and carbon for a 36mm motor, which ist definately stiffer. the one for the kb killed the teeth of the center-diff due to a minimum of flex.

aluminium is less stiff then eg. glassfiber, carbonfiber, and it is possible that it is still flexing a little.

Connected to the chassis it also reduces the forces at the center-diff mount. its made of plastic, and it could flex like that very little as well.

[eovnu87435ds]

i thought so too, but apparently that is supposed to be a flexing chassis, and bolting the mount to it would make handling suck

hmm, allright. still, I guess the rest is still able to flex, it's just the center of the chassis. front and back wouldn 't change, I don't know.
maybe u just try it, and when it sucks, just remove the screws.

cool truggy btw!
