As my two runners sit currently!
It was about time for me to post my Ascender, still mostly stock but lots of fun. "thumbsup" I love kits, but bought the RTR for several reasons:
Short on time these days
I like the stock red with white roof paint job (I need new airbrush too and can't decide which one to buy :lmao
Wanted to try out the Vaterra waterproof esc (all my other crawlers use Tekin FXR)
RTR tires can be baked off to install beadlocks
RIght out of the box, this truck is 100 times better than any Axial! It's got all the options that I've spent tons of money on for my Axials already incorporated! The fit and finish is way better, no sloppy rod ends, plastic links, wobbly knuckles and c-chubs, loose sloppy transmission input shaft that floats up and down and walks in and out on the topshaft bearings, shocks that don't leak, tires and foams that don't fold over to the rim on sidehills....I could go on but you get the idea. Plastic is much sturdier and more precisely molded too. There were a few screws little bit loose (better than stripped), that was easily fixed during my initial pre-run once over. The front end had a little kinda wobbliness to it during sharp turning that others have mentioned, I found the front axles (CVDs) were out of phase with each other. If you turn the wheels all the way to either side and look at the CVD pins and barrels they were 90* off from each other. Simple and quick fix, pulled a steering knuckle off, pulled axle (CVD) out slightly to disengage it from the spool (ring gear), rotated 90*, pushed the CVD back into the spool, and reinstalled the knuckle with C-hub attached. Torque twist is not really noticeable until I put the big tall Blazer body on, but it doesn't hinder performance much. I lowered the ride height by loosening spring pre-load adjusters (with suspension un-loaded, wheels off the ground) until the springs just touch the adjusters.
This thing crawls great! "thumbsup"8)
Mine came with HD driveshafts and pinion gears already installed, need to take a peak inside the diffs and see if the heavy duty pinions are there too, but I bought spares when I bought the truck just in case.
Installed the HR aluminum diff covers, nice pieces. As soon as the SSD Diff Covers were released, I replaced the Hot Racing with SSD Diff Covers, which are much stronger, thicker and nicer looking little machined aluminum works of art.

Spools, Axle Gears and Shimming:
I've been beating mine hard too and so far everything's holding up just fine. Even did some forward reverse full throttle the other day, just to see if the diffs would blow and it's still on original set of HD pinion gears and drive-shafts. Also been letting everybody drive it, hopping and bouncing at full throttle on steep climbs, steering full lock in both directions, lots of tumbles mostly on 2S, but some 3S.
Shimming the diffs (spools), my Blazer came with both shims on the wrong side in the front diff and the rear had one on each side, so I swapped both factory shims to the side to push the ring gear closer to the pinion. I read on here somewhere that somebody added a third shim to the same side. The stock shims are about 0.004" thick or just under, the CRC (Calandra Racing Concepts) 8mm shims I bought are about 0.006" thick, I added one to the stack for total of three shims about 0.014" total thickness. The diff still spun smoothly, but it barely had any backlash so I took one of the stock thinner shims and moved it to the opposite side (away from the ring gear) which gave me just the right amount of backlash. This ended up being 0.010" thick on the ring gear side and 0.004" on the side opposite the ring gear. Added a little extra grease to the gears too.
CRC (Calandra Racing Concepts) shims, IIRC I bought shims at LHS RC Country in Sacramento, but I see A-Main Hobbies has them online and they are good source. Shims for ring gear (spool) and pinion, I bought steel Calandra Racing 6mm shims for the pinion and 8mm for the ring gear...just in case they needed tightened up a little (only the spool needed shimmed).

Shock Springs:
Vaterra Ascender Upper Shock Spring Set Soft,Med,Hard(2ea.) PART NUMBER: VTR233029. According to Horizon, "The RTR and Kit come with the "medium" rate springs. These can be identified by the Silver mark on the spring itself. The firm springs are identified with a green mark, while the soft spring is identified with a Yellow mark." I want to soften the short upper springs to get ride height down little more while still maintaining spring contact with the adjuster and bottom spring cup at full droop, the soft springs should do the trick!
Lower Shock Spring Set Soft, Medium, Hard (2): ASN VTR233030, these are color coded same as the upper springs.
RTR Ascenders come with silver (medium) upper and lower springs on all four shocks.
Batteries:
I usied Turnigy 1300 and 2200 3S smaller packs in it to start with, because it's what I was using in my SCX10 Honcho and Wraith, but have since bought several good hardcase shorty packs that fit the stock battery tray very nicely.
Turnigy 1300mAh 3S 20C Lipo Pack
Turnigy 1300mAh 3S 20C Lipo Pack
Turnigy Heavy Duty 2200mAh 3S 60C Lipo Pack
Turnigy Heavy Duty 2200mAh 3S 60C Lipo Pack (US Warehouse)
Switched to Team Orion Carbon Pro 4500 100C 7.4V Shorty Pack, I like the low speed control of 2S without swapping pinion.
I bought several SMC Batteries Factory Spec 7.4V Shorty 4400mAh 60C Inboard (Product Code: 4460-2S2P)
http://www.smc-racing.net/index.php?route=product/product&path=67_91&product_id=121
Current LIHV batteries run for 3-4 hours

Transmission and 2-Speed (Two-Speed) Option:
Will install two-speed tranny later so 2S should be fine, may go hotter motor later too.

Body Height and Mounting:
I lowered the body two post holes front and rear, trimmed 1/4" off front and rear of body, the sides still have about another 1/4" between them and nerf bars. Looks better and can go down one more hole front and rear on the mounts, I've already trimmed the front and rear of the wheel openings to clear the stock tires with the body lowered. Only trimmed off about 1/8" at front and rear edges of wheel wells to clear with lowered body, I think the body looks pretty good at this height, but am tempted to go one hole lower front and rear...leaving as is for now. It's easy to cut more, difficult to put it back. Might trim the front wheel openings at the tops to clear during full flex travel and turning as it still has very minor occasion rubbing there and I like the look of the body.
Tires:
Vaterra TSL listed as 4.5" tall, but I haven't measured them, the size is perfect for the Blazer body. They are pretty sticky once cleaned with Simple Green and water, driving them more helps too but not as quickly. They work very well on all terrain, including mud, loose dirt, sand and rock and clean out all except the stickiest clay mud. With more horsepower, they should clean out even sticky clay mud.
Foams:

RTR Steering Servo:
Spektrum SPMS605, 9KG Servo, WP, Metal, 23T
Gear Type: Metal
Servo Type: Digital
Speed: .24 sec/60 degrees @ 6.0V
Torque: 161 oz-in @ 6.0V
Current servo in all my Ascenders, HS-7955TG High Torque, Titanium Gear, Coreless Ultra Premium Servo
Part No: 37955S
https://hitecrcd.com/products/servos/ultra-premium-digital-servos/hs-7955tg/product
Stock plastic servo horn and servo are hanging in there for months, but I have replaced it with Hitec HS7950-TH servo, second RTR gets the Hitec HS7955-TG which survived my Wraith, but wanted more power there. Dynamite aluminum servo horns are on both trucks, they fit very snugly on the servo output splines, are perfect length using the outermost linkage hole, have survived on my SCX10 through Axialfest, and are inexpensive. These are available in black, blue and red. They are nice and compact, the lower arm profile allows me to get full suspension up-travel of the shocks and just touch the arm at full compression (stock plastic arm and many clamping horns do not). Clamping horns are unecessary on most RC, a good quality metal arm with Loctited screw and washer is all that is required.
Part Number: DYN2561
1/2 Machined Aluminum Servo Arm: HRC Black

Body looks sweet on my Wraith but probably have to cut too much to clear the tires. 8):ror: Ascender front end peaking out of right side of pic on workbench, need to get some of my trail pics.
