Good tips

Thanks guys!

So most of you use a front diff? Have anyone seen or used a solid axle (spool) on this car?

I tried to run a front diff but decided to go back to the one-way because of better lap times. I haven't seen a solid in particular but there are many ways to turn a diff into a solid.

Default CRF on GPX4

Ole C my friend runs a CRF on his GPX4 and I also run one on my RRR. I do his clutch and motor tunning for him and have gotten this motor to perform extremely well on both cars. For the track you are talking about running on the gearing you want to use is 20/26, 60/54. And for your clutch you want to run 1.1 spring tension and .5 clutch gap depending on the traction of the surface you run on, if high traction you can go 1.2 on the spring and .6 on the clutch. motor will have more than enough bottom and insane top hope this helps.

Guys,
Had a win on the weekend with my RTR car with the TZ3 engine in it. The car seems to handle much better than my Pro GPX-4 and I find this strange as all the settings are the same all I can think is maybe the extra chassis flex makes the car grip up better than the stiffer Pro chassis still having a few clutch problems with the car freereving between gear changes.

Hey Taffyjnr5 the internal ratio of the GPX-4 pro is 2.4238 so for the 1st is 47/16*2.4238=7.12 and for 2nd is 43/20*2.4238=5.21

Hey Guys, been reading alot on the Hobao,as i got one for my 30th birthday from a bunch of mates, pretty cool little toy thats for sure and addictive TOO!!!

The make i have is Hyper 10 with a H12 Nitro Motor in it....!

Question how differant are these from the GPX4-PRO

I have only had the car for a week, done a rear drive gear & rear drive belt due to rocks getting inside and splitting the belt....! OUCHIE

The plastick gear was melted on half side, as i think the rock got the better end of the day LOL, but spen AUS$40 and she no worries again!!!!

What tips can i get for a Fast Circuit CAR - setup wise any links etc for my Hobao Hyper 10 & What setup is good for a Drift Style set up?

Some good links to help a ROOKIE like myself understand this new crazy Hobby my mates got me, now i need to learn a whole new world!!!

Regards
Frankie

Hi,
I am currently using Mugen diff oils with 30k oil in the rear of my Pro car and using 50kr ear and 100k front in my RTR Sport class car and I have found these to be the best for most tracks so far. Hope this helps you out.

I have actually started to run 100k diff oil in the rear of my car with a front one way and I've become a better driver. Putting 100k in the rear has taught me throttle control like never before. Definitely try 10k, 30k, and 100k to see what works best for you at your local track. Experimenting will only make you a better driver. Good luck.

Hi,
I run both a Pro with a OS TZ3 and a RTR in sport class with a OS TGP and have a lot of success with both cars at club level.

Funny you should say that i have started experimenting with the oneway and rear diff oils currently using 50k rear and it has made me a better driver.
