Finished my 2nd GTP - Page 3 - RC-Monster Forums

Well word was that Novak was coming out with some 1/8 motors. I'll wait and see what that is all about.

With sensored you have better startups with taller gearing/high rollout ratio. Tekin has a boost too for their 1/8 lower kv motors.

Right now the RX8 is super smooth even with my 47/23 gearing in sensorless. My other GTP which has the 4000kv motor, starts up good with 51/25 gearing. But when I dragraced it, I had 51/18 in there with the 4000kv motor. Instant starts with the RX8 without sensors. Sensored is not really needed for what I do.

Sensored is good for those boost+turbo running folks with their roar motors.

Upgrading the ring gears is recommended and getting those metal diff case caps is a plus when going with a higher power setup.

So are they a factory upgrade or aftermarket part? Got a link for them? Anything else that really needs upgrading? I bet these things are hell on tires. LOL

I think the dirt oval comes with the hardend ring gears allready, but I'm not sure.

The ring gears are factory upgrades and the metal diff case caps are from king headz.

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.
