Also just installed an 18 tooth pinion and lightweight spur and I have to say "wow". It really woke the car up. I had the stock 15 and seemed to be more on full throttle all the time to keep the car going. Now with the 18 the car has tons of torque and is easier to drive around the track. I am also getting longer run times as I am not full throttle all the time. Also learned to only have a very slight amount of gear backlash (mesh). Was running too much.

quick question for you all. i am coming from RC helicopters where slop in the mechanical system can make the difference between a perfect heli and one that wont even leave the ground. The Vorza rocks! but there is so much slop in the steering, wheel mounts and the drive train, i cant beleive the car can even drive straight! Is this something that all cars/trucks have? do i need to go in and start shimming and getting rid of all of the slop? Do i except it as the norm? any guidance would be great.

im afraid that if i solidify everything, ill find out that this is the reason it doesnt blow up when its going 60mph! there is probably +/-10 degrees of play in the front wheels!

thanks
Well from experience, but i am only a tech rookie, you want a little play. Example: I installed the aluminum rear hub carriers on my vorza. There are 2 set screws on the back side that holds the suspension shaft in firmly the first time i hit something I snapped the suspension shaft in half. I would think all that stress if tight you are gonna start breaking stuff on a regular basis. Any other opinions please post.

did you keep to the 48 tooth or did you drop teeth on the spur gear? i heard 18t is the max you can run with the 48t spur. still running the 2200kv motor? i also noticed that the 44 and 46 tooth spur gears are not yet available.

I upgraded to the lighter spur but still 48t. I think you can get a 19 with a little finessing of the motor mount holes. But 18 seems to suit me fine. Still running the stock 2200kv motor. You can find the 46 and 44 on hot bodies site I believe.

i have been reading this thread and finding that Hot Bodies buggies share many of the same parts for the Vorza. are there any parts besides the spurs for the HB buggies that are worth getting for the Vorza?

thanks

And the parts you find on the hot bodies site are usually cheaper than the hpi site. The Vorza is just a factory converted electric from the d8 platform.

Default 2650KV flux motor

im confused about this motor. The HPI manual says to use that motor with a 6s set up to make the vorza a rocket. RC Car Action special Electric addition also used the 2650 with a 6s pack and monster pinion to make the car go 100mph. But if you look at any website that carries the motor, the descriptions all say to use no more than a 4s pack? i like the motor, but im really 'down' with burning it up or toasting my speedo.

Any have the answer?

thanks

Are you mixing the two motors?

The vorza comes with the 2200kv motor
My understanding is that the 2200kv motor can be used with upto and including 6S, the 2650 on the other hand is designed to be used with upto 4S.
I wouldn't have thought using the 2650 motor with 6S would damage the esc, my understanding is that it could damage the motor due to the high rpm.

i'm running stock pistons, red springs, and ae 50wt in the rear and it still seems to be a bit soft.

would it be more benefitial to change the pistons to the 1.2's or just keep uping the oil? don't know to much about what the different shock pistons accomplish?

You might try lightening the front a little. Just a thought.
I run:
grey springs/ae 40wt/1.3's up front
Red springs/ae 45wt/kyosho 1.2 8 hole sp pistons/and a small chunk of the d8's air filter foam under the bladder cap
I cannot say that it is perfect, but it sure is better. Everyone that has driven it said they liked the setup.

I run the 2650kv motor on 6s with no problems, and have been doing so for a good few months.

Default i got an answer from HPI about the 2650kv motor

i inquired about whether the 2650 could be used with 6s or only 4s. Here is HPI's answer:

"Thank you for contacting HPI and Hotbodies customer service. You can use 6s lipo with the 2650 kv motor, but you must be aware of the temperatures and RPM’s that it is creating. You will have much shorter run times because it will draw more current the faster it goes. Again it will work, but we do not recommend it because of the constant monitoring that is necessary. If you have any other questions feel free to contact me."

i run the vorza with Spektrum telemetry so keeping an I on the temps is not a problem for me.
