i have tornado bb and i am having a bit of trouble with the dogbones. 1st i dont know what size the front and back driveshaft is?2nd the dogbones are so fragile im wondering if there is any way to support it. please help.

The dogbone parts numbers are in your manual and no I can't see supporting a dog bone. I'd put your truck on a block and rev it to mid to full rev and watch the wheels if they like bounce up and down if you know what I mean then it is probably a wheel issue.There are other reasons if you are constantly breaking dog bones.

jacky boy is trying to say that he broke his back drive shaft is and he doesn't know what size it is. i kinda found it hard to understand.

see jack? people wont murder you if you ask a question that might be stupid. dude, stupid question = one u never ask. remember that.

I miss read what he posted I thought he meant to the wheels. Either way I don't see a way of supporting the drive shafts.

yeah thats what i thought he said to. i got him into the rc car hobby thing and he lives in my neighborhood so i just ride my bike over to his house and drive our cars around so, i know what happened

Hmm I am not sure if this will work but check out HPI parts Kinderman. I know a large number of their 1/10th scale truck parts will fit the Redcat's 1/10th scale trucks/cars. You may be able to find a part that is more durable. Check out their website at www.hpiracing.com

The dogbone part number is 6061 and no you can't support them. If you don't have tiny slivers of fuel line in the drive cups then your going wear out dog bones like no tomorrow. You need to take ALL the dog bones out and check the drive cups and put a small sliver of fuel line in the drive cup to take up the slack so they don't slap around in the drive cup. Less play=Longer life. Just don't get them to tight, you should be able to move the A-Arm up and down and turn the wheel with no binding.

No HPI dogbones won't work.

Do a search I posted some HPI part number drive shafts that work perfectly. They are also a little bit better made around the ends and dont snap the tips off as easy. Ill see if i can find them

Here ya go. And Allaboutfunhobbies, check your second post, you might wanna edit your post in this thread

OH YA, I forgot all about those. Good find and I stand corrected, I appoligze, lol.

lol no apologize necessary! im glad to come back from last summer and see you still trying to help out!

im asking what size the front and back driveshaft are/ example:55mm

their in your instruction manual although im pretty sure that they have it wrong cause it says the back driveshaft is bigger than the front but its not sooo i guess ill switch the numbers and....... front driveshaft - 87mm rear driveshaft - 55mm
hope this helps. the manual is reallllllyyyy crappy

buy the hpi rear shafts, use the part number in the link i posted, you wont be sorry
