Hopping up the Hound

[julesbristol]

Hi chaps,

Has anyone tried hopping up the DF-02 gravel hound? I've sorted the bearings and drive shaft, and got a no limit ESC and 7 turn motor on the way. Waht else is worth doing? Cheers

7 turn motor eek I smell burnt plastic!

try the alluminum shocks and harder springs.

also http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXDU13&P=MLwill increce the ride height and traction

i also have alloy hexes and the wheels nevers come off.

i have a concern about the 7T motor. I think it will need lower gearing than the 16/70 that the hound will go.

post your results from your firt run. i think they are going to be very intresting.

the fastest motor i v put in my hound is the ss5800. But i thing a good 7T will be faster . Let us know.

ps

an alloy motor mount and a motor heat sink might be nececery.

thanks chaps. what should i change the gearing to? i've got bagfulls of pinions from my TT-01...

[Andreas_Bl]

i would start from the smallest pinion you have and work my way up. but dont know what sizes you have. I m waiting for an lrp bullet this week and i ll try it first with an tamiya 11t and the 16t pinion(lowest i have) and see how that goes. I think it ll be ok but with yours i dont know.

And their is an othe matter. their 4 ways to drop your gear ratio.

1st you can drop pinion size.

2nd you can inc spur size.

3d both the above

4th you can put smaller diameter wheels.

Solution

4th is out of the question in our case(the ride is too short as it is.

3d is out because 2second is out.(i dont know if the make larger than 70T

so , leaves as with 1st. smaler pinion.

I noticed in my hound that with the stock motor mount. if you put a 16T pinion the motor is accually touches the chassis. so with a smaller pinion where the motor is going to go ? I might have to dremel the chassis and the center axle with it.

these for now. Maybe i m all wrong and the 7T wont get warm at all.

please post your details specify motor , esc ,gearing and temps if you run it before than me.

sorry for the long post and my eng.

no thanks very much. very helpful indeed. i'll be in touch with results! Jules

i tried a rear wheel drive conversion in the hound(i just removed the center axle & the front diff & bones)

the motor was a bran new Speedgems extreme 17T(put a 20deggree timing on it)and the esc an lrp bullet(no limit).

gearing 19/70

the results was unbelievable. these motors have unbelievable punch and top end. (they punished my rear tires with only one batt!!)

I cant even imagin a 7X1 in there.

but i m ordering one right now.

ps

I know that i need some new chrome wheels with that sweet body and not painted stocks.
