Well I got a wraith kit around January of this year and ended up sinking my life into it trying to make it crawl how I wanted. But no matter how much tweaking or what parts you buy, a scale style build is pretty limited on ability. So I watched the classified and found someone wanting to trade a xr10 roller, well I wouldn't say roller as it still needed pieced back together, looking to trade for a wraith. Well I jumped on it and took a chance I would like it better. After a little while I came across more and more parts from some good people on this forum. After a lot of reading, watching some of you guys rigs on YouTube and such, I got a basis on how I was going to setup my rig. Keep in mind this build is on a budget as I have two kids and hours at work are slow this time of year. I know I am not up to par with a lot of the rigs on here, but this rigs does what I want, 98% of the time. When I got this it was chassis, axles( with all vanquish parts), slw wheels, rovers, and titanium links. The axles were loaded with RC4WD hardened gears, so no worries there. I installed my servo on the axle and since I already had a fxr and 35t tekin, I decided I would stick with that for now and order another tekin combo. I started assembly the night I got the rig.

A few days later I got my electronics in and tried to get them as small as possible. First try, and I call it a fail.

Since I didn't like my electronics the present way and I didn't like them on the chassis, I ordered a rowdy racing electronics mounts and tried again. I moved my bec to underneath the servo. I think I did a little better on this smash job as it fits perfect on the mount with clearance for the links.

Now for battery mounting. Since I really don't have any patience and couldn't wait on saving a few dollars to buy a battery mount, I searched my basement and found some aluminum plate and decided to try and build my own. A little trial and error and I eventually came to this. Which I like but I think is a little to tall as it touches the same time my tires do when on its roof.

So after all this I just wasn't satisfied with my chassis or the rig break over. So I went on a hunt for a cheap chassis. I came across a Viper II and for some reason really liked the look. So after about a week and a half of talking to the RCC member, he decided to help me out and meet in the middle on the price. The chassis was flawless when I received it minus a few skid scratches. I have a practice course I built in my basement and after running the viper II on it I am in love with its break over as compared to my bjv4 chassis

For shocks I went with inverted traxxas big bores with mini t springs. I like this setup a lot. I am just having problems with shock oil setup. Its either to thin and causes massive axle hop and rollovers or to thick and my rig out runs the shock on obstacles.

I decided to try and lower the weight a little, so I removed my homemade servo armor, trimmed wires down to only what is needed and removed my wheels to drill them.

Not the difference I was looking for but it adds up. After five or six practice runs I decided to sipe my rovers as I have read it help out a lot. And I agree after siping the tires and adding a soft tuning ring in the front, it is much better on steep or sharp angled approaches. Here is how its sits for now. Waiting on some Custom Fiber pieces, and saving for some Holmes Hobbies motors.

Will update as parts come in and progress happens. Any technical advice would also be helpful as I am learning as I go and learning from great articles and build threads on RCC.

Looks real great!! Keep up good work!!

I'm in process of building my daughters crawler as well. Sits about just like yours just diff chassis ( chaotic)

Have fun crawling!!
 
KustomKreeper8606's First MOA

Well since my first comp to attend is at the end of this month, I decided I better get on the move trying to get things done. I got my RCBro knuckle weights holders in, but they were out of stock on the weights. So, I made my own. I had a brass hammer in my toolbox that hasn't been used in years, a drill, and a dremel. It was time for a little inginuity.

Both full and half together equal out to 3.5 oz with bracket. Also after reading and reading that shaving HB rovers works wonders. I decided it was worth a shot. Haven't tried them yet. But believing it works. 99% of RCC can't be wrong.

Well, checked the mail today and had a package. Inside was some sweet Custom Fiber pieces.. Going to hate to see scratches on these.

Motor Guards...

Took the crawler out today behind my work. There is a creek with aalot of river rock and such. Well all was going well until I noticed the rear motor was acting a little funny. So I unplugged the battery and started looking it over. The rear motor was blistering hot, with just a tad of smoke for a few seconds. Wondering what is causing. There is no shorts, motor is advanced 6*. Could the advance be doing this. Also its 96 degrees here, don't know if that is affecting it or not. ESC didn't get warm at all either.
 
Well after having motor problems, I took it as a sign from the RC Crawler gods that I needed better motors. So now I am waiting on my Holmes Hobbies 5 pole 17t Pro's to come in. Should be here by Friday. Will post pics when they come in. But in the mean time, I got a set of sedonas in. These tires are freakin wide. So I decided to narrow them. This is my first attempt at this. Going to mount them up today.

Here's a pic of stock sedona, shaved rover, and narrowed sedona, to get an idea of how much I took out.

Well got my motors in yesterday. After reading a little I decided to go with a 12t pinion for gearing. Figured it will give me a little more creep control. I reshrinked my fxr's. As I had to removed the heat shrink because I accidentally pulled the receiver wire of one of the fxr's. Got everything all buttoned up, plugged up one of my new batteries. Checked steering, it was a go. Pulled the throttle and only the back motor worked. Pulled it again and both worked. Starting to get frustrated, I tried one more time. When I pulled the trigger sparks shot out the front motor, but no rotation. I decided to call it a night as I was getting ill, and it happened to be 2 in the morning. Going to try and figure this out after work today. And also going to try and finesse my universals for a little more steering without binding. Will post pics of axles later tonight.
 
That sucks! Gear mesh binding maybe? Bad bearing locked up?
I just had ruined a motor guard with a fire.. might want to take it off, as to not turn it crispy..
 
Motors and wheels spin fine, bearings are good. While waithing on my motors, I tore down the axles and checked bearings, cleaned, and regreased everything. Before installing motors I checked them. They were not locked or anything. Comms and brushes looked good on both motors. I am going to pull the motor and electronics and do a little trial an error.
 
I'd check the gear mesh on them like Troy mentioned. EGB just had this exact problem where he wasn't getting motors to turn. Ended up his pinion was actually too far out on the shaft and was binding on the cover.
 
Motor problem has been solved. One of the mount screws was just barely touching the armeture. Enough to not let the motor start. But able to spin by hand and I also slightly changed the gear mesh as it was a tad to tight. Both together were my problem in my opinion.
 
Well my tekin hotwire came in at noon today. Hooked my esc's up and found out why they acted differently while under forward throttle engagement. One was on firmware .28 and the other was on . 32. Updated the .28 and now they work together flawlessy. Also did some dremeling on my universals and gained a few extra degrees of steering without binding.

Just put these HH 17 turn 5 pole Crawlmasters to the test on my practice course. These have to be the smoothest motors I have ever seen. Unbelievable creep control. Great torque. Now I see why everyone runs Holmes Hobbies..........
 
Well my first comp was to be this weekend. But and there's always got to be a freaking but, I was practicing on my lunch break an took a roll. A nice skinny, pointy spear shaped fxr killing rock, hit just perfect on my fxr and poof. Magical smoke. No power to the front. Removed heat shrink to see a fried board. But, yes another but, I am hoping to find a used fxr asap. Hopefully I can make this comp.
