Also the 1/4 servos have stronger gear sets in them to take the higher shock loads a heavier truck will see. I was also powering the servo directly off the reciever battery instead of through the reciever, which alot of 1/5 guys do. It gives the servo some more power and insures the reciever doesn't burn out from the increased load placed on it.
Edit: Cool project man, I really dig the large scale stff, can't wait to see it finished with vids.

so do you think i should go with a 1/4 scale servo then? i heard the JR HVT has huge teeth on the gears. the stock setup on this uses a 1/4 servo for the steering and a standard servo for the brake. i was just going to use standard for both. i did find these 1/4 servos. defintely the strongest i have found so far in the 1/4 size.

to linc:
i weighed the chassis as a BL roller and it weighs 19.3 pounds. that was with the battery trays on it. so here are the other stats, according to memory.
servo: 2.5oz each. x 2
2215 Neu: 25oz.
NeuEnergy 5s Lipo: 22.5oz x 2
Hydra 240HV ESC: 7.7oz
So all together i get a weight of roughly 24.5 pounds. I am gonna add on another 8 to 16 ounces for wire, screws, mech brakes, mounting hardware for esc, etc. so the finished product should weigh in at 25lb or just over.
This is the first build i have done where i havent tried to shed weight and been concerned with weight.
