That is how I press motor shafts in and out, with my drill press and a 5mm flat punch.

All the New parts are on their way

RCM 4.3:1 Ratio 1/8th truggy diffs
Center CVD's
AXI 4120/14 outrunner motor

Hopefully this build will get back "in gear" when they arrive.:yes:

I will be waiting! I have a solid axle truck that wants to be converted direct drive too :D

Dont forget my hyper7 wants direct drive too :)

just got done reading the thread. Bravo Sike. Well done.

She is a beauty.

Got a little bored waiting on parts to get here. So I decided to enlist the Revo in a weight loss plan! :lol:

She went from 9lbs 8 ounces, without batteries, to 9lbs 1 ounce. When I change motors, another 4 ounces will drop to make the weight 8lbs 13 ounces. I'm thinking about maybe trying the Badlands tires/wheels, so that might shed a little more weight.

I decided to get rid of those gawdy "sideboards". I shaved them on down. This allows me to lay my Lipo's down for an even lower center of gravity.

Ok, maybe 4 Series 10,000mah Lipo's are a bit bulky. How about 4 Series 5000mah Lipo?

OR, if I can settle on a HV ESC that I like, How about 8S1P A123?

I also trimmed and slimmed up the motor mount some.

My Tower Hobbies order should be here tomorrow. The rest of the parts will be here either Tuesday or Wednesday. I'm ready to get this thing going. :yes:

This is a very cool project. It is really tempting me to try something like this... :whistle: Also, how heavy are your 8s1p a123's? I'm thinking of dumping my 4s 8000mAh and going HV...

Bye:mdr:

8S1P A123 is 1lb 6 ounces. What ESC will you be going HV with?

Do these Wheels and Tires look funky? Good for Asphalt Speed runs I think.

I LOVE the Phaltlines!

Sike, this is coming together really nicely man. It's looks fine with the 10Ah lipo's on there... that would make for some nice runtime at that, 40 mins at least at 40 mph.

Thanks.
 

Hey Sikes thanks for sharing this project info with all of us. This thread has been a pretty educational venture. We are learning at your expense and that will help a lot of us decide how to proceed on some of our own builds. The trucks setup looks really good, and the direct drive is a unique concept for that truck. With those street wheels and tires you should be able to get some pretty fast runs. keep up the good work. We are having fun just reading through your experience.:lol:

Thanks, I seem to like the jazz controllers the 55-32-10 or something like that. I have not decided yet though... Also, those tires look great!

Off topic question, would a 63v 3300uf 85c cap be ok on my quark 125? I know its not low esr, but since its so big, would it work? I have 2 of them....(from an older bass amp:oops:)

Bye:mdr:

It not being a low ESR cap means that it is a lower quality version. It's internal resistence is higher(slow to charge, slow to drain), so it may or may not help performance. Also, the 85C rating, is it's maximum operating temperature. The low ESR versions are 105C rated.

I have a few extra 63v 1000uf 105C that are low ESR. Interested? Drop me a PM.

Parts ARE IN!!!!
 

Wooo Hooo! Look what I got!

I got the new motor also.

I've got to hand it to Mike on this one! Fast Shipping and great service. These new diffs look beefy! I guess I better go get to work on this! :yes:
