Default Soze's UMG10 - 80's toy/cartoon theme build

The UMG10 was intriguing enough for me to pick up another SCX10.2. Bonus that it came as a kit. As soon as I saw the driver included with the kit I knew what I what direction I wanted to go with it.

I mulled over how detailed to make this thread since the SCX10.2 is pretty well known at this point. Decided to go ahead and just document everything just in case there are newcomers to the hobby.

Part 1: Axles

Let's get started!




We need parts from these bags.




Step 1 - diff gears






Step 2 - Going to give these 1 piece housings a try before I replace them.








Step 3 - Front Axle






Step 4 - Rear Axle






Step 5





lockouts for multi-piece housing replaced with just screws for 1-piece housing.




Axles are complete!

Part 2: Links and Shocks


These are needed for this section






Step 6 - Steering and Panhard Links






Step 7 - Attaching steering and panhard links






Step 8 - Front lower links






Step 9 - Front upper link



Forgot picture of completed link.


Step 10 - Mouting front links






Step 11 - Rear Links






Step 12 - Mounting rear links






Links all mounted up.




Need this stuff for the shocks



Step 13-15 - Shocks




So my kit was missing all 4 pistons (Axial QC at it again). I had to steal them from a second SCX10.2 Cherokee kit I picked up. In the meantime I called up Axial to tell them that they were missing so that they could send me the pistons (AX30132).




UMG10 shock shafts on the left, Cherokee Kit shock shafts on the right.




Good ol' Noleen SF3 Shock Grease










Filled oil with low pressure setup






Shocks all good to go.




Part 2 complete.

Part 3: Drivetrain


Parts needed for this step. DON'T FORGET THE ADDENDUM PARTS & INSTRUCTIONS!. I almost forgot there was the addendum package. Not following it would have resulted in a 305mm wheelbase and apparently not molded quite correctly transfer case. (more on that later).




Step 16 - Transmission shafts






Step 17 - Transmission assembly




Yup, the top-shaft play is still there. It's ok, I've got a Vanquish Top Shaft for SCX10.2 (ebay) waiting in the wings...




Step 18 - Transfer case. Make sure you use the Addendum transfer case. I couldn't see any differences between the addendum piece and what was provided in the kit, but I ended up using the addendum piece out of caution. After asking around... apparently the original kit provided piece had some mold issues on the inside of the case. The Addendum piece supposedly has the insides molded correctly to prevent any binding of gears. I have not had a chance to open up the transmission case again to look at the differences in detail, but I will put pictures up if I dig into it again. The other confusing aspect of this step is that the addendum calls this part of the instructions "servo mount".








Step 19 - Motor mount plate.








Step 20 - Spur gear and slipper assembly






Step 21 - Motor and pinion




Holmes Hobbies Trailmaster Sport 550 21T






Onto the driveshafts




Step 22 - Front driveshaft






Step 23 - Rear driveshaft






Step 24 - Mounting the driveshafts.




I have the rear driveshaft on backwards in this picture... corrected later on.




Step 25 - Mounting transmission to skid






All done with part 3!

Part 4: Chassis Assembly


Poaching stuff from these bags




Step 26 - battery tray






Step 27 - Servo mount. It always amuses me how over-complicated this assembly seems to be.




Directions call for those 2 pieces under the battery tray, and for them to face in opposite directions. I don't know why or what they're for?




Step 28 - Mounting the servo




I ended up having some servo horn clearance issues with this particular servo. I had to use spacers for the time being, but I don't think this is the final servo I'll end up using... just what I have on hand.






Step 29






Step 30 from Addendum




MAKE SURE YOU USE THE ADDENDUM INSTRUCTIONS! This will give you the correct wheelbase.








Step 31 from Addendum






Step 32 from Addendum






Step 33 from manual - Mount front axle assembly (Addendum instructions skip from Step 32 to 37... so be aware that you need to jump from Addendum Step 32 to Manuals Step 33-36... back to Addendum steps 37, 38 and 39).






Step 34 - Front shocks mounted






Step 35 - Servo Horn




Boom Racing low profile 25T servo horn






Step 36 from manual - Attaching panhard rod








Step 37 from addendum - Rear links mounted.






Again, driveshaft backwards, but has since been corrected.




Step 38 from addendum- Rear shock mounting.






Done with part 4 update.

Part 5: Electronics, Bumper, Wheels/Tires


Step 39 from addendum - receiver box






Decided to not fully assemble yet, since my electronics choices are still in flux. There is a good chance that I'll be switching up the servo mount + battery arrangement as well.




Step 40 - front bumper








Step 41 - Mounting tires. I really like the way these tires look. I also like the plastic beadlocks wheels as well.












Step 42 - Mounting wheels onto chassis





Part 5 out of the way. Almost done!

Part 6: Body and Rear Cage

COBRAAAAAAAAAA! Ok, you guys probably get what the title means now. I think it was brought up that the helmet style was an odd choice given the background of who used that type. I thought it was similar enough to a Cobra Trooper helmet to make it a less offensive/controversial choice to be able to stick with it.


Steps 43-45 - painting body and parts, applying decals. I decided not to black out the fenders or rear panels this time, as I felt I wanted a "fuller" body of color. I blacked out the inside of the lexan, and painted the blue and flat cleared the outside of the lexan.

Colors Used:
Tamiya PS-4 Blue
Tamiya PS-23 Gunmetal
Tamiya PS-5 Black
Tamiya PS-55 Flat Clear
Tamiya XF-15 Flat Flesh













I really really wish I had a vinyl cutter for the Cobra emblems.




I'm glad this kit came with an interior. Real nice touch. I used the decal shift console at first, but later replaced it with the shifters from the parts tree.




Kudos to Axial for using reflective decals for the mirror. I don't know why non-reflective decals are still being used in some other kits.




Step 46 - Front grille assembly






Yup, Axial is at it again with that thin strip below the front grille. I think they're just trolling us at this point. However, I will say this one came out better and the grill seems to contour and grip the body much better when mounted.




Step 47 - Light lenses and buckets






Step 48 - Mounting side mirrors.










Step 49 - Snorkel assembly






Step 50 - Interior






Step 51 - Mounting the interior










Step 52 - Starting the rear cage assembly






Step 53






Step 54






Step 55 - At this point I discovered that Axial QC has yet blessed me with a shortage of screws 2.6x6. And an overage of incorrect screws 2.6x10. I ended up having to use some extra 2.6x10s that were provided instead of 10 2.6x6 screws that I was supposed to use.






Step 56 - Spare tire mount






Step 57 - Mounting the cab to cage.




Made a hole at the top of the cab for extra screw to support mounting to the top of the cage lining up with existing cage screw joint.










Step 58 - Mounting body to chassis








Stock form build complete.

Now it's time to put some of those Axial tree parts (ammo cans, rifles, etc.) to good use. Need to figure all that out.

Soze, that is awesome! I almost bought one of those recently. Ended up getting TRX-4 Tactical for my wife to come out and play with. Next plan is to pick up a pair of TRX-4 Sports for my boys (7 & 5 years old) and then pick up this Axial for myself. Love how you did your 's. Nice job!

Appreciate it! TRX4s are nice. This one will be a more of a challenge to drive with its short wheelbase, but it adds to the variety of my rigs.

Soze, are you running this rig on 2s or 3s? Also, do you typically not run a BEC? I haven't run them and haven't had brown out issues. Just curious what your thoughts are. Thanks man!
