I called HPI Monday morning and expressed my concerns with a brand new $320 plus rtr car and was unhappy. If these issues did not exist, I absolutley would LOVE this car. Looks pretty freaking sweet and feels SOLID to me. I love working on my vehicles so installing these parts are rather fun BUT it would be nice to have a true RTR vehicle...
HPI customer service is sending me a 72t spur gear and 46mm dog bones. HPI customer service is PHENOMENAL I just wish there quality control was the same.

FYI this forum ROCKS!!!!
I emailed them and they didn't even replace the dogbone that was lost. All they did was send me 2 orings in the mail it rather ticked me quite off.

I was going to buy one to play with on my drive way . ( I won't use a race car for that) Guess Ill just keep Tc3 for Now . If they come out with a kit form with CVDs . Turnbuckles and no electronics (which I can't use ) , I would buy one . It looks like it could be a good car for Spec racing

Spur gear stripped on mine while testing the SpecR axles. Couldn't get the stock 66t so went with the 75t. Drives better.
Wasn't suprised that spur stripped. I've run more 3s then 2s.
Tires at still terrible. Just too soft, no consistent traction. Can't imagine what surface they were test on. Think they were picked for looks, not function.
Gonna try running different body first. Porsche body stills feels tail heavy when driving. Have to keep shocks stiff do body doesn't hit pavement.

How about trying another brand of spur gear? When installing, double check that they are meshed correctly.

Maybe that can help.

Just finished un-boxing the Sprint 2 while patiently waiting on the hop-ups from hpi until I start running the Flux.

The spr parts are in stock at tracing right now. I just ordered a set for the front and rears. Get em while you can. They are the only ones domestic that have them. Was $35 shipped for me.

So HPI sent me a 75t spur gear and my LHS said that I have to run a different pinion. I called HPI and they are sending me the right pinion..............

75t spur gear should be running with a 27t pinion
65t spur gear should be running with a 32t pinion all from factory specs.

Right now I am running 75t spur gear with 32t pinion

I received and installed the Spec-R CVDs yesterday, and wow, what a difference. Honestly I wasn't able to use the car with the stock front dogbones and had actually taken them out and run RWD only just to play around a bit. Obviously going back to AWD makes a huge difference, but with the CVDs installed and not having to worry about turning too hard, hitting a bump, etc., the car was quite enjoyable to bash around.

I'm still not sure about the stock tires; their grip seems OK (on asphalt) but with them being oversized, you run into the problem of the body needing to be trimmed back, plus I don't think they track all that straight. That might be a result of the stock servo though.

Has anyone tried the Flux with standard size TC tires and/or a higher-torque servo?

Thanks,
Endaar

Default Wheels/Tires

I changed to the HPI vintage 31mm wheels and tires for front and rear. Works great! The stock slicks were terrible on the asphalt street I test on. I put in adjustable front tie rods and set them for no toe in. Car doesn't wander and works excellent. I also put in the SpecR CVD's. I do have a question. According to my manual, the stock spur gear is 75t. Are some coming with the 65t? I did order two 75t from Robson racing just in case of stripping. I do agree a new person would be pretty upset about the dog bones. I personally upgrade every RC I have so was a lil upset about the issue at first. HPI hopefully will fix this on later releases.

Mine came with the 66t spur. Tuning the 75t now. I finally changed bodies. Porsche body was just too heavy for car. Running a old Viper body now. I don't like the tires but I'm giving them a second chance now.
Had to loosen shocks all the way back to out the box settings. See how it goes but expect to try different tires soon.
