It's the stock motor from the Rtr kit. Flux MMH-4000 motor. I wasn't being very nice to it a bit throttle mashing. Lots of quick take offs and hard braking. I never checked the mesh. No big deal at least this is an easy fix.

Nice pic Mr. Wood looks like your driving the car hard the way one should. One member here is bashing his off road... Parts break from time to time I see some spares in the UK on ebay you can grab until the hpi hop ups come available.

I do believe the new design will prove to be a winner down the road just need to work out some of the bugs on the car since it's a totally new design from hpi.

I just purchased a Sprint 2 Fallken Porsche minutes ago (smoking deal) and converting the Camo Falken into a beauty shelf queen.
I'm not giving up on it either. My last run before I lost the dog bone, with a different body, showed real improvement.
As for it being s long term success, only time will tell. If it becomes a good 3s vehicle then it's good with me. Since no sales figures are every released, makes it hard to judge.

Questions?? Which Model?

I have the Porsche RTR. It has the dog bone issue but he SpecR axles fixed that. In reading all 8 pages of this topic, is the Porsche the only one having problems or are the other two also having problems? One other issue I have is the steering to the right goes way too far and the upright hits the frame. I am using a Spectrum radio and have to turn the Right steering travel to 40%. I also have the servo centered but have to go almost full left on the rate. I tried moving the servo saver but will not go so rate is centered.

From the ones I played with on the shelf the flux seems to be the only one with the problem. The only steering issue I'm having is it's a rather pain to get the steering alignment set. So it doesn't drift one way or another.

Any feedback on that servo saver? I'm actually wondering how it would compare to the Xray servo saver.

If they made a kit, I might actually buy one just for kicks.

As far as I know the FLUX is the only one with issues, although I believe adding two O-rings to each side of your diff and not putting any in the axle side will help the issue. Also dialing back the steering a bit I'm sure would help the issue even further.

As far as your issue, I'm not sure what exactly what the problem is. Do you have any pictures showing the problem?
I can say that there are hard stops left and right molded right into the chassis that limit the amount of steering. On mine, when I hit those hard stops the steering knuckles are pretty much touching the C-hubs both left and right. It's just about impossible for the steering not to be equal (assuming you still have the stock non-adjustable steering links) unless there's an issue with your servo not being centered and not giving you full stroke one direction. Or you have the steering bridge mounted in the wrong holes.

You should be able to pull the servo saver off and get it fairly close to centered. Just make sure you center your radio out before you re-install your servo saver.

I was expecting the servo saver to be garbage, but it's actually pretty stout and works good, it's also adjustable so you can set the tension.

But just be warned that they do not give you different spline options with the car, so you are stuck with 25T servos (futaba, savox, etc.)

Does anyone know if the nitro parts of the rs4 will work with the car?

Default Steering

I got the steering problem fixed. It seems the stock tie rods were either loose on the ball cups or the right was too long. I put adjustable links on and problem gone. Will wait for upgraded steering set to come out. What servo are people using to replace the stock HPI? I tried a Savox std. and the mount was about 1/8th inch to long. I couldn't get screw holes to line up and it wouldn't fit back in the chassis. I would post pics but don't know how on this board. I don't have any photo sharing accounts.

The HB/HPI D413 servo saver parts are shared. So the option to use any servo is available

Back up and running. Installed the Spec R axles this morning. 3s test run, minus body, went good. Thanks for suggesting them.

Thanks to Mr P!nk for confirming the fit.
