I decided to get my boy a Senton blx back in March as an early bday gift, and I mean way early. His bday is now coming up in a week from today and let’s just say Senton was in need of a refresh. Over the last few months we’ve beaten on this thing and it keeps coming back for more. My major down time only began when we found loose/dry dirt. We quickly went through 2 motors this way.

What has started as a hobby and time spent with my kids outside has become a full on addiction. I blame the forum! Seriously though, I titled this boring as to the more senior hobbyist this is a mild build but to me it was my first real step into doing more than just general maintenance. Without the forum and member insight I’d be in the dark so thank you to you all.

As you can see she was in poor shape.

I decided to try and fix the poor design of dirt getting into the motor housingsince this is what I’m sure led to motor bearings failing.

I went with a hobbystar 3670 3020kv motor. Going to leave it with a 15t pinion for now. I also went with the steel spur this time around.

I kept the esc stock for now as well. It’s been good to me so far so I left it alone.

For wheels and tires I went with proline lp trenchers on raid adjustable hex wheels for the stock 14mm hexes. The offset is pretty far out there so we’ll see how it holds up. I was back and forth on going full on monster truck but decided to stay close to stock tire size. I still had to trim the rear to minimize some rub.

I felt some customizing was in order so I sanded down some stock springs and color matched them to the new body. I’m not expecting these to hold up. Really just to look cool before he gets his hand on the remote.

Upgrade list -
Fast eddy bearing kit.
25kg servo(testing with stock saver before k124)
Hobbystar 3670 3020kv motor.
HR Adjustable motor mount.
HR pivot balls.
Tbone front bumper.
Arrma motor fan.
Steel 57t spur.
15T pinion.

All else has been kept factory and has seen basic maintenance.

I need to reinforce the body still before his bday and I think I’ll put another factory rear bumper on since this one is tweaked some.

Looks good man! ? I'm gearing up to do a similar build and mine will be a first build as well....just waiting on parts. I choose the same motor as you so I would be interested to hear how it runs. I am going with the blk/grn Senton 6s body and keeping stock bumpers for the time being but they will be new as mine are trashed. I also went with same brand servo but the 20kg version. I also opted for the 2.8 trencher tire on the f-11 wheel with a 12 mm hex conversion as I wanted more ground clearance for where I run. Still trying to decide on what motor fan I want.

Anyways, good job on the build and let me know how that motor works!
 
@BustedBudget nice set up. What size pinion are you going to use? I found the arrma motor fan that comes with the 4s line works well enough for me. You could always move to something else more powerful I suppose. Plus with this motor you can keep the factory heat sink. I’ll keep you posted on how she performs (y)(y)

Good to know about the motor fan. I'll check it out, thanks. I like the idea of keeping factory heat sink. I will likely run the 15T pinion though I also have a 13T...see how it performs with the 15T and go from there.

Yes def keep us posted on how she performs ? I saw @Rich Duperbash run that motor in his Senton and I was sold! Man that thing ripped! I'm sure your wills too! Happy bashing ???

Come to think of it...I think with that motor you can run the stock 20T pinion...I believe that what Rich was running in his vid...
 
@BustedBudget I did some test runs on 2s and it was still plenty fast. Definitely was noticeably slower. 3s will still be for me while he gets it on 2s. I’ve been told an 18t is a happy medium so I may do that eventually.
 
Just got done with the final shake down. Holy cow I’m in love. This thing is so torquey with the 15t pinion set up. I can’t imagine how much more fun she’ll be by stepping up to 18t or back to the 20t pinion. Question for those who have run this motor, should I cover this part of the motor with tape since it’s not sealed like the blx motors?

Decided to try this for reinforcing key weak areas on the body. Let’s see how it goes.

Good to hear it is running well! I was amazed by how torquey the thing was in duperbashes video. It would wheelie all day on that 20T pinion. Pretty wild. Unfortunately, for me that motor is on backorder ? So, in the meantime I picked up an arrma 2050kv motor kit of 6s Kraton. I'm going to pair it with a sidewinder 4 esc and run it on 3s. Should provide plenty of torque and run cooler. Also picked up the 4s Kraton suspension arms and steel turnbuckle to give it a wider stance and help it corner better without flopping over as it tends to do.

I picked up a roll of the gorilla tape to do the Senton body and hopefully get a little longer run time out of it. Cant say I've tried that stuff but I'd certainly be interested to know how it works out! Probably a heck of a lot easier to apply! Lol
 
@BustedBudget thats a bummer on the motor. Damn covid. I’d like to see it with the wider arms on there. Did you ready have the longer 4s axles?

I’m sitting on an 18t and 20t pinion. As he gets better at driving and when it cools back off I might try it.
 
Yeah it was a bummer, but what are ya gonna do. At least I found a relatively cheap replacement in the meantime. My 4s axles are on the way as well in the same order. As are the 17mm hexes and 3.8 Kraton tires...and a bunch of other parts LOL I basically ordered all the parts to build a 4s Kraton. Except a chassis. I'll likely order an M2c chassis for it.
 
6 minutes in on his first bday run and this happens :ROFLMAO:

I knew I should of put the rpms on right away. Well they are on now.

In the short time it ran, all I can say is wow it’s a beast. I can’t imagine stepping up to an 18t on 3s.
 
Looks like the young lad is having a blast! ?

Truck looks like it's working (and flying) good as well ?

Ha! You know you had fun when it comes back that dirty! ??? Those trenchers throw a lot of dirt don't they? ?

Here is a pic of mine from a few weeks back after a snow run...looks very similar...

@JAM Question for ya...you running the 17mm hex prolines with the hot racing 12mm to 17mm conversion with an offset?...

WOW that looks relly cool. love the colors you did. I here duct tape under the body works well or even painting it with the rubberized paint does good to. I have never did these things so I can't speek from experience just what I here on thie forum.
 
@BustedBudget thanks! Just noticed your wheelie bar looks just like mine after a couple hard rear landings haha.

I’m using proline raids with 14mm adaptors. The wheels have different hex options themself. 6 screws thread in to lock them into place. They have 12/14/17mm options and you simply remove them and can swap them around. I went with 14mm to use stock hexes but the offset is kinda crazy. Still looks good and is more stable now. Havnt had it out on Dirt just yet though.

You would just unbolt and the whole inner section pulls out. I put an adapter on top for reference.
 
Ha yeah...I broke one of the support arms on the bumper and it kept doing that...has since been fixed.

Ah, ok...I did see them...I was just curious because I have a set of trenchers with the 12mm hex rims and I'm having fitment issues I'm not sure how to rectify...not enough offset to get them away from the steering components. I was able to shim the rears and get them to work but no such luck on the front and its rubbing real bad.
