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.

Step 13-15 - Shocks

47745456352_d894159e08_b.jpg



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).

46881379425_1617d77045_b.jpg



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

47797613411_05cc7e4004_b.jpg

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).

46881378975_fa7275c1a3_b.jpg



Step 16 - Transmission shafts

47745455022_b4d28444e5_b.jpg


46881378505_b267de6c31_b.jpg



Step 17 - Transmission assembly

33920691778_0a553eac85_b.jpg



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...

46881378035_8cb6191590_b.jpg



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".

33920690998_d89efe2b04_b.jpg


46881377565_236c4246af_b.jpg


33920690528_dfa7cf0f62_b.jpg



Step 19 - Motor mount plate.

46881376955_0d3a8634d8_b.jpg


33920689868_3e23cdb430_b.jpg


46881376305_38e5487a31_b.jpg



Step 20 - Spur gear and slipper assembly

33920689228_a82e042169_b.jpg


47008446874_900ef302b2_b.jpg



Step 21 - Motor and pinion

47008446444_2627ef6942_b.jpg


47797614071_2e72a48241_b.jpg



Onto the driveshafts

33920688608_c708ef94bb_b.jpg



Step 22 - Front driveshaft

46881375065_2228da7c2a_b.jpg


40831466973_f08ef590ae_b.jpg



Step 23 - Rear driveshaft

47008447354_1f9fb9ea6e_b.jpg


46881374505_b31e15fd73_b.jpg



Step 24 - Mounting the driveshafts.

40831466363_e453f15e7a_b.jpg



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

46881373825_474cc48613_b.jpg



Step 25 - Mounting transmission to skid

40831465803_6cf9ffe16e_b.jpg


46881373265_285ecf375d_b.jpg



All done with part 3!

Part 4: Chassis Assembly


Poaching stuff from these bags

40831464983_ebb4d9ab76_b.jpg



Step 26 - battery tray

46881372125_5d4568f662_b.jpg


40831464203_f030dc8a19_b.jpg



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

40831463903_5bc75c1b10_b.jpg



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?

40831463553_e3ee9131ed_b.jpg



Step 28 - Mounting the servo

40831463183_13bf1aaecb_b.jpg



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.

47797629621_6ca88551b6_b.jpg


46881365545_103aa9b3e7_b.jpg



Step 29

40831462683_e4d00d2ecf_b.jpg


47797628381_d94a0b7cab_b.jpg



Step 30 from Addendum

47797627871_6dfdcc05cb_b.jpg



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

47797627441_8f279f2182_b.jpg


47797626981_83a2e75358_b.jpg


47797626551_63012739e2_b.jpg



Step 31 from Addendum

47797626141_f970570ce0_b.jpg


47797625801_99e39875c4_b.jpg



Step 32 from Addendum

47797625481_7f9ed364b9_b.jpg


33920682908_d90f375031_b.jpg



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).

47797622431_9a07265013_b.jpg


47797621911_d35e6b758f_b.jpg



Step 34 - Front shocks mounted

47797621421_5c87e8c223_b.jpg


47797620951_3198f4c232_b.jpg



Step 35 - Servo Horn

47797620441_72ac5af1e9_b.jpg



Boom Racing low profile 25T servo horn

47797620281_d7152cff9d_b.jpg


47797619631_404c3f3dc0_b.jpg



Step 36 from manual - Attaching panhard rod

33920680378_77c950e3d9_b.jpg


47797618731_f47361a6a9_b.jpg


33920680128_3074782b59_b.jpg



Step 37 from addendum - Rear links mounted.

47797624801_60587c60a5_b.jpg


47797624351_9e4a830f19_b.jpg



Again, driveshaft backwards, but has since been corrected.

47797623901_187cc63513_b.jpg



Step 38 from addendum- Rear shock mounting.

47797623311_232083a1bb_b.jpg


47797622891_0126440c62_b.jpg



Done with part 4 update.

Part 5: Electronics, Bumper, Wheels/Tires


Step 39 from addendum - receiver box

47098032244_4306e523d3_b.jpg


46971282055_39554bb497_b.jpg



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.

47098031264_0c49885d83_b.jpg



Step 40 - front bumper

46971280625_571a60234b_b.jpg


47098029914_8e4cecf35a_b.jpg


46971278825_23a96fd99a_b.jpg



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

47098028394_1b4e4e781e_b.jpg


46971276475_6839d42bb2_b.jpg

46971274075_d3a67a755f_b.jpg


47887397541_f46b3f4fd7_b.jpg



Step 42 - Mounting wheels onto chassis

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
Tamiya 5mm Masking tape for Curves
Frog Tape (for general masking)

47835389402_cf71368feb_b.jpg



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

40921003223_f14f950706_b.jpg



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.

47835387492_fd89c60a75_b.jpg



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.

47835386232_b5d636c8ef_b.jpg



Step 46 - Front grille assembly

47835385362_0cb0bed939_b.jpg


40921000653_b20d51de0d_b.jpg



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.

47835384022_cb9c5ab36b_b.jpg



Step 47 - Light lenses and buckets

47887387951_e46468faa7_b.jpg


40920997893_756d0a7bcd_b.jpg



Step 48 - Mounting side mirrors.

47835382172_4c0f2e942b_b.jpg


47887385611_bb80255152_b.jpg


47835381262_dfa4195021_b.jpg


47835352172_3155c0bf40_b.jpg



Step 49 - Snorkel assembly

47097984414_d134822c88_b.jpg


47835380312_1344467575_b.jpg



Step 50 - Interior

46971258375_ee8dcbc3b8_b.jpg


47835379032_cbd70d27ec_b.jpg



Step 51 - Mounting the interior

47835377212_d43497d101_b.jpg


46971256135_d36ab692c7_b.jpg


47835367262_db1d81d2ee_b.jpg



Step 52 - Starting the rear cage assembly

47835375442_c7e44ae293_b.jpg


47835373772_61cccd5054_b.jpg



Step 53

46971253305_990f51ffce_b.jpg


47835353562_a10d394d5b_b.jpg



Step 54

47835353112_6f3194ee18_b.jpg


47835352632_5d7977a754_b.jpg



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.

47835371162_9800ccbcdd_b.jpg


46971250955_0a3d88f6e8_b.jpg



Step 56 - Spare tire mount

47835369352_eaec1d6b2d_b.jpg


47835366282_fd877ea309_b.jpg



Step 57 - Mounting the cab to cage.

47835368302_466b3cee3d_b.jpg



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.

noticed the kit has the ti coated shock shafts again. Kinda glad to see that. The older kit shocks were the best axial shocks.

In for thread title ;)
Looking at your selected colors I have no idea where you are going with this... Looking forward to seeing the rest!
 
You're missing red for what I was thinking.
Dont give any hints! I want to be surprised ;)

Cobra HISS variant?? I got nothing lol

I'm really sorry/not sorry that you have no life and an unlimited expense account to keep putting up these awesome build threads for us. :ror:

This is definitely a departure from mainstream but I like what you did there! "thumbsup"

LOL, yeah family life doesn't leave much time for other stuff, but I find time in the evenings to do stuff.

Unlimited expense account! Hah I wish! Most of this is funded by selling off my stuff from my older hobbies that I've left.
 
Ermahgerd the Cobra theme is perfect. Nicely done, and great walkthrough.

I'm digging that servo horn. I had to clearance my panhard mount to make my Axial aluminum horn fit which was annoying.
 
It looks great! "thumbsup"

Thanks for warning me about the grille! This is a body for me to avoid.

When you said cartoon theme I was picturing a UMG10 body on a Tamiya Comic chassis. :ror:
 
Looks great Soze! Love the Cobra theme! Seeing this took me back 37 years to my first G.I. Joe's!
 
CO - BRAAAAAA!!!!!!!!

hahaha awesome!!!
I totally took a stab in the dark on that!
Hey you know I have some A.R.B.C.O. decals for custom vehicles. I cant remember the name of the site where I got them. Maybe it was reprolabels? Anyway I can send them your way if you want!
(For those not in the know, ARBCO was cobras super clever "disguised" name for thier businesses usually run by the twin crimson guard commanders tomax and xamot. IIRC...)

GREAT WORK SOZE!!!
I still have not yet "figured" out a way to tie in my two favorite hobbies of RC and figure collecting. I think you nailed it here!
