Finished my 2nd GTP

Strap some dry ice on the motor !!!

What powerplant did you go with?

BigMaxx Pletty w/23T pinion.

I wanted the pillow ball setup in the rear, but didn't want to spend an arm and a leg for it. So Ebay to the resque and bought OFNA Rear Pivot Ball Kit, MP-6 Part# 31297 for 14 bucks plus shipping. I had to shimmy it a bit, but now I have a nice 13" wheelbase. The thing is on rails and zooms like mad.






Here's the bigger motor. It's scary to drive with this beast.

LETS DRIFT THIS ONE TOO !!!!!!!
One added rule ! YOU NEED TO HOLD IT LONGER, AND SWING IT MORE SIDEWAYS !!!

I could probably make my other GTP a so called drifter. I would have to use the 1520 motor for the unlimited torque with that chassis.

I figure I'll post this here too.

The Bigmaxx is a 1800W 2300kv motor and about the same length as Castles 1520 motor. It runs on 4s Acepow. The other Pletty that I blew up was a 1000W 3000kv motor.
The Bigmaxx has too much torque and I'm actually considering using the current limiter. 1000W or like most 1512 motors are perfect for the GTB.


Motors that I have used in both GTP's are:

Hacker C50 13L 1874KV and 6L 4060kv motor (As smooth as sensored and perfect amount of torque w/quick spoolup)

Plettenberg Maxx 3000kv and Bigmaxx 2300kv motor(4 pole motors that spool up like a 2 pole)

Castle 2200KV and 1520 1600kv motors(both are torque monsters, but slower spool up)

Tekno Neu 1512 1400kv motor(Way smoother than Castle motors)

Tekno Neu 1515 2700kv motor(Fast smooth torque monster)

Tekin 4030 1400kv motor(Even smoother than the Tekno Neu)

Lehner XL Basic 3100kv motor(Tough little motor, but an XXL would've been better)

Hacker C50 Maxx 14.4 3600kv motor(Same can size as the C50-L motors, but less torque due to shorter rotor magnet)

LRP 2500kv 1/8 motor.(13mm rotor just doesn't cut it. Worked well in lighter vehicles. Power is equivelant to a C40-L Hacker motor)



ESC's that I've run in the GTP's:

Losi 1/8 ESC(Ran 6s A123 with Tekno neu 1515 2700kv motor. Blew up after firmware update)

Lutach LT-10s 120A(10s A123 is overkill with a 1400kv Tekno neu)

Tekin RX8 with cap bank(favorite)



If anyone who wants to run a Hacker motor, the B50-L or C50-L are best. Difference between them is motor can size and rotor structure.
B50 has sintered rotor, 36mm can diameter
C50 has segmented rotor, 44mm can diameter

We have already seen what happens when you drift!!!! $400 GONE with the pull of the trigger.

I don't think you have tried enough stuff in those cars but I do see a remarkable trend in the ESC dept. Burned 1 Up, used 1 the size of a netbook and then the "ONE"!!!! Over and over and over and over.

Yup, the one and only. The one that got a bad rap, due to user error(using subpar batteries)

I'm about to get another one, because my back-ups backup needs a back up.

hehehhe. Next year I'm getting the 8S Castle ESC. No need to get the 12S version, as total power out is about the same per Castle. Just have to upgrade those ACEpow batts with 10awg wires and it should be good. MGM also has new ESC's out, but Euro conversion puts them out the pricerange.

My GTP pulled a peak of 2668W with a 4s pack over the weekend. Tires were run down Ofna blue foams. Basically I was doing burnouts, speedruns and power sliding. This also posed a problem with the ESC. My voltage dropped twice to 8.55V for 0.002 of a second and the RX8 didn't respond. I only had 5 led's on, so I didn't thermal. Impressive on the RX8 part to detect that V-drop that fast.

So I found the Acepow 4s pack limitation with my 1.5D 1515 2700kv motor and 47/28 gearing. I can however ease on the throttle and not have the lipo cutoff trip.

Datalogger used was the new Eagletree V4 which has the 50hz logging capability. Connectors are EC5. RX8 has 3 extra caps. Motor plugs are 6mm.
