Crawler Innovations "Big Blue" - 2.2 KOH Crawler; wraith based I purchased this rig from Szczerba last year. He has a detailed build thread here: http://www.rccrawler.com/forum/2-2-s...mblin-koh.html I mailed my wraith axles, scx trans and electronics from the White Lightning Wraith to Szczerba. The build thread on that wraith is here: http://www.rccrawler.com/forum/axial...ng-wraith.html Szczerba installed the parts and mailed me the rig. All it needed was wheels & tires, a battery and some minor tweaking. It's been to a number of National & local G6's. It's also been used as a test truck for Crawler Innovations products. The axles have seen better days, and the truck is due for a complete rebuild. I figured now would be a good time to create a build thread and share the truck. https://farm8.staticflickr.com/7442/...0414ca8c_o.jpg https://farm8.staticflickr.com/7072/...4a772327_o.jpg https://farm8.staticflickr.com/7200/...f0aeef3e_o.jpg https://farm3.staticflickr.com/2829/...6b50a72f_o.jpg https://farm8.staticflickr.com/7064/...f123845c_o.jpg https://farm3.staticflickr.com/2908/...f470a0d4_o.jpg |

Re: Crawler Innovations "Big Blue" - 2.2 KOH Crawler; wraith based time to show it some love"thumbsup" and thank you for outstanding products:mrgreen: |
Re: Crawler Innovations "Big Blue" - 2.2 KOH Crawler; wraith based seen thing in person & its one rig you don't to be in front of ! its a beast ! you need some DmG axle skids for that thing !! pm me your shipping info buddy & ill send u some :mrgreen: The DmG |
Re: Crawler Innovations "Big Blue" - 2.2 KOH Crawler; wraith based I have a number of upgrades planned for the rebuild. I have been collecting parts for over 6 months now. All new axles are up first: https://farm3.staticflickr.com/2929/...5a84984c_o.jpg A huge Thank you to Vanquish Products for their support. Thank you for allowing me to continue to be a Team VP driver. "thumbsup" When you want the best in aftermarket quality, No One beats Vanquish Products. We have come to learn the stock axle pinion bearings can't handle the load of 4S & 4 pole brushless. I will be installing bushings for the pinion. We have also come to learn that not all gear sets have the same gear mesh or teeth contact. The Axial Under Drive gear set has the best gear mesh and the lowest gearing @ 3.30 (IMO A gear set be offered in 4.30 or a ratio closer to a 1:1 crawler). The Kyosho steel shims are a must when setting ring and pinion back lash. The new axles will have these parts installed: https://farm3.staticflickr.com/2882/...a2dcf53c_o.jpg |

Re: Crawler Innovations "Big Blue" - 2.2 KOH Crawler; wraith based I like my builds to be clean and simple. The wiring under the hood of this rig is a mess. I lost the CC MMP 1Cell ESC last October at Crawlapalooza when the fast moving stream carried this rig down stream and deposited it in a four foot deep pool. The ESC had not been waterproofed and it fried the micro processor. I installed a MMP to keep it running for local events, but the wiring was a mess. Have you noticed how the Castle BEC's have 1 foot of RX wire? LOL Welcome to OverkillRC - Overkill RC has the fix for messy wiring: https://farm4.staticflickr.com/3749/...84b30d59_o.jpg The pair with blue handles is a ratcheting crimping tool for servo/RX wires. I have tried other cheaper tools and they suck. These tools I purchased from Austin at Overkill RC work amazing. I have used them to clean up the wiring on several drift cars and crawlers already. If you build a lot of rigs, these are tools worth buying."thumbsup" |
Re: Crawler Innovations "Big Blue" - 2.2 KOH Crawler; wraith based Amazing Rig. Looks pretty dang real. What are you running for the upper links? Same as the lowers but with a bend? |
Re: Crawler Innovations "Big Blue" - 2.2 KOH Crawler; wraith based Thanks for posting those shims. I have been looking for a good source for the 10x12's. |
Crawler Innovations "Big Blue" - 2.2 KOH Crawler; wraith based Nice to see the rebuild. It needed some TLC. |
Re: Crawler Innovations "Big Blue" - 2.2 KOH Crawler; wraith based Looks like a killer rig, great styling too. I'll be lurking around following this rebuild for sure. |

Re: Crawler Innovations "Big Blue" - 2.2 KOH Crawler; wraith based Let's get started: https://farm3.staticflickr.com/2869/...50faee86_o.jpg I decided to build an all new trans for Big Blue instead of a rebuild of the old one. I'm going to use the build up of the trans to demonstrate some mods that can be done to any SCX / AX Trans. Parts List: VP Trans Housing BWD FOFF Motor Plate Axial Top Gear & Shaft RRP Steel Idler Gear RRP Steel Output Gear C.I. 5mm Steel Lightened Long Front Output C.I. 5mm Steel Lightened Long Rear Output RRP Steel 60T / 32P Spur Gear (For Traxxas E Revo) combined with RRP Steel 88T / 48P Spur Assembly (For Axial SCX/ AX) https://farm4.staticflickr.com/3756/...809cfb74_o.jpg |
Re: Crawler Innovations "Big Blue" - 2.2 KOH Crawler; wraith based The previous trans in Big Blue used an Axial plastic trans case and Kimbrough 62T 32P Spur gear. Although they never gave me a problem, if and when an errant pebble got in there to destroy the plastic spur, it was an hour to R&R the part. I knew on the rebuild I wanted a steel pinion and spur. I also wanted to gear down from before. On the final trans, I used the backing plate from this kit: https://farm4.staticflickr.com/3801/...9a7e6086_o.jpg The stock plastic housing is cheap and effective, but for tight tolerances... As an example, the previous trans is pictured below, notice how the RRP Axial Slipper plate hits the BWD motor plate: https://farm3.staticflickr.com/2863/...e99807ef_b.jpg Same trans, but with the Axial slipper unit: https://farm3.staticflickr.com/2937/...69e78b53_o.jpg Same trans, but with the RRP #7960 60T Steel gear for the Traxxas E Revo Modified to the stock Axial Slipper: https://farm4.staticflickr.com/3716/...2743d439_o.jpg https://farm3.staticflickr.com/2850/...2650eec8_o.jpg Here is the gear modified to fit the stock Axial Spur Gear Assembly: https://farm3.staticflickr.com/2834/...25426bbb_o.jpg I modifed the gear using my dremel and a diamond wheel point. It cuts very quickly: A link to the bit is here: 7122 Diamond Wheel Point / Model: 7122 I have also done this mod using a small round hand file. It's a cheap and easy way to get more steel spur gear gearing options. I use a modified 56T steel spur gear on my AR60 based Monster Truck that is a pure basher on 3S lipo and 4 pole 3800KV brushless. Here's a video of the MT in action: <iframe src="//www.youtube.com/embed/AA5Zjs-yT8g" allowfullscreen="" frameborder="0" height="315" width="560"></iframe> With Big Blue it was important to me to gear down for a smoother start up and greater drag break. The 60T E revo gear will accomplish that a lot more than the 56T from the slash. If you do this mod, you will need three custom length bolts to mount the spur gear to the slipper unit. I used 10mm length with 3mm aluminum spacers to get the exact length I wanted. The spacers also help to hold the spur gear securely. https://farm8.staticflickr.com/7079/...0055af4f_o.jpg https://farm4.staticflickr.com/3689/...bb9e1e8c_o.jpg https://farm3.staticflickr.com/2875/...07902cbe_o.jpg 8) |
Re: Crawler Innovations "Big Blue" - 2.2 KOH Crawler; wraith based Looking good Eddie!! Hmmm...wonder how much $$$ will be riding in the car this weekend?? :roll::twisted: |
Re: Crawler Innovations "Big Blue" - 2.2 KOH Crawler; wraith based Continuing on with Big Blue: RRP which is short for Robinson Racing Products; finally released a New Steel Output gear this year"thumbsup" For years now I have used the Hard Anodized Aluminum gear with no real failures to report. I have always wanted steel from an American Made company and now we have it. https://farm3.staticflickr.com/2859/...409c1122_o.jpg Here's the aluminum version: https://farm8.staticflickr.com/7246/...d144f0b3_o.jpg RRP released a Wraith part # Steel idler gear last year that is a couple dollars more than the existing SCX / SX part # Steel idler gear. Steel Wraith: https://farm8.staticflickr.com/7243/...87c74426_o.jpg Steel AX: https://farm4.staticflickr.com/3753/...f6cec67f_o.jpg In laymen terms, they are the same gear. So if you are a baller on a budget, the AX version is the one to buy.;-) https://farm4.staticflickr.com/3809/...ccd8953a_o.jpg |

Re: Crawler Innovations "Big Blue" - 2.2 KOH Crawler; wraith based Although I am leaning towards not making the 5mm Transmission Outputs again (and I am currently sold out of them; so please do not ask), I still want to put the information out there. I'm using long front and rear trans outputs on Big Blue. The 14" wheel base basically requires it. I'm using 5mm outputs because the axles have 5mm pinions. The previous trans had 6mm outputs. https://farm4.staticflickr.com/3810/...0527c9de_o.jpg The dimensions of the outputs are identical. It does not matter which direction the outputs stick out of the trans. The C.I. Long Front output design has: https://farm8.staticflickr.com/7179/...fe48072f_o.jpg The C.I. Long Rear output design has: https://farm8.staticflickr.com/7303/...006f1e7e_o.jpg Nice, Strong & all Steel; https://farm6.staticflickr.com/5209/...78f680e5_o.jpg All the gears inside the new VP Trans housing ready for grease and final assembly: https://farm4.staticflickr.com/3753/...2ee080d3_o.jpg The BWD Motor Plate: https://farm6.staticflickr.com/5263/...47d94179_o.jpg . |
