Joywrex's Creeper Build (First RC ever)

[joywrex]

I updated the badges on the bug body. Gotta represent the corp.






BTL Servo Installation, just in time for the new version to come out...






The tie rod link was too long (notice the bow leggedness)

All I had was a file, and yes it took a long time.




Installed (This picture was taken with a iphone 4s with pretty bad light. Still a pretty decent picture)

[joywrex]

some crawling:
















I don't know how it possibly rolled off the cliff from so far away but it did...




No damage woo!

This spot has been the bane of my existence. I don't know what to do to the car to make it get over that overhang...Besides dig.

How much weight are you running in your tires?

Like already asked...wheel weight front and rear...also looks like your foams are too stiff...your tires are getting traction but they aren't wadding up.

[joywrex]

The front wheels weigh 12oz total. The rears weigh 9oz. I can't add any more weight to the front wheels, there just isn't any room unless I get new wheels.

I haven't cut the star shapes into the outer foams. Maybe that could help.

This is the foams i have:

HB WD Rover & 5.5 Double Deuce Foam Combo

Front Inners: Firm Inners
Inner Front Width: 2.00
Front Outers: Soft Outers

Rear Inners: Firm Inners
Inner Rear Width: 2.00
Rear Outers: Medium Outers

[remmuh]

I agree with too stiff foams. Also your wheel base may be too short for that climb.

[joywrex]

I have a lot of stuttering when moving as slow as possible. I replaced the batteries in the controller and stuck the antenna out away from stuff. It seems to be getting worse, now when I go in reverse the servo tweaks out too.

my electronics do that 2. im not spasic on what the issue is, but its either the servo no haveing a neg wire going to the RX, or it is just the radio that im using.

[remmuh]

With the video being sped up I couldn't tell if it was glitching. but now that you said that it does I think along with the foams being to stiff the glitching is a big problem as it causes wheel hop.

iv got some weigths for the stock creeper rims that would add 7.5oz to ur front that go on the outside of the rim

thats an interferrence or power glitch..the servo twitching...check all of your wiring for damage and make sure the antenna wire is out and not wrapped around anything...also check your Tx batteries...

Id say see if someone with soft tires will let you borrow thier wheels/tires and see if you can make that climb....i just think your foams are too stiff cuz the rears wont cut under that bottom ledge. I also think your weights are fine.

I had a similar problem when I put in a FXR speed control. Turned out that with the Castle Bec I just had to run the ground wire from the servo to the rx and problem solved. I dont know what your electronics are but this worked for me and a few other people I know. Strange though it would not glitch at all with 2s, only on 3s?

It glitched with the 2s also, just not as bad.

[joywrex]

Well I was doing a little wire management to make sure everything was in its place on the rig and i apparently reversed the connection wire between the receiver to the esc...

The receiver promptly filled my house with delicious cancer-smoke.

I ordered a new receiver. I hope that it the only part that got fried!

lame

Should I do star cuts in the outer foams? Do you do that?

i made them plaster cast of the rim then pulled a female off the male and then pored the lead in the female mold they were .1oz difference
