Akumu - bomber build
 

Always wanted one but got a used yeti first (a few months ago) because it was the best bang for the buck. Then the oportunity to trade in my SCX10 v1 came to get a used bomber (rtr version)... it was bashed but came with hopups, what an ugly truck hahaha

Immediately started cleaning the livery and kit, did a thorough check of tranny and axles... no issues. Just the livery and color, getting on my nerves, also the stupid dogbones had to go. Found it had Boom Racing knuckles, c-hubs, steering arm, rear lower links, vanquish sway bar v2, metal drive shafts.

http://vlozity.net/akumu/bomber/akumu-bomber-02.png

Installed a sensoreless ezrun wp80 esc, 2600kv motor and 20kg servo, all waterproof, and tested it... this truck seems to love to tumble a lot, the stock foams suck.

Anyways, got pumped to get me a new kit version so i can start fresh. A friend is buying my old bomber soon.

Got Vanquish stage 1 kit, new beadlocks (vanquish k.o), used the metal spur gear from the yeti, moved Vanquish sway bars over from old bomber, Vanquish servo mounts which i placed 1mm spacers underneat the mount to lift the servo higher so i can use the servo arms longer throw.

i just got the new PL TSL Super Swampers 2.2 installed (will take pics soon), my Crawler Innovation single stage foams are ordered from RCMart along with an AXE540 sensored combo. The PL stock foams... geez, my fingers hurt trying to mount it, after 4 hours trying, i gave up and used the stock foams temporarily.

Here is a shot of both rigs...

I still need to purchase Vanquish motor mounts, maybe the rear lower links too.

Oh and a used cherokee body to play with, loved what Tim Askins did on his build.

Really great photography skills on display!

Congrats on your Bomber(s)!

Sounds like you've got a lot of work done recently...

Please give us your impressions of the HobbyWing AXE system, it is so far not very common here in the USA.

BTW - which kv-rating motor did you pick for the system?

Re: Akumu - bomber build
 

Nice! I specially like the front shocks pushed forward to the axle... it is something I want to experiment with...
One question: that servo horn isn't too close to the tie rod?

Re: Akumu - bomber build
 

the kit version manual states that the shock be installed on that forward hole. i actually have not run the new bomber yet, waiting on my CI foams before testing.

Actually there is clearance on the horn and tierod, it is the ball ends that hits the tie rod. what i did was move the servo up by 1mm (not shown in any of the photos), this removes any binds and scrubing.
forgot to mention i had to lengthen the steering rod so that i can use the bottom servo arm position for more angle... this created binding which wa resolved by moving the servo high.


Thanks Durok!

I will do a review, but FYI it will be installed on the SCX10 II which now sports the Toyzuki motor mount (traded the scx10 v1 for the order bomber here). I think i will get a sensored 4 pole for this one funds are available.

"thumbsup"

Re: Akumu - bomber build
 

@Zka17 my bad, the manual had it on its default hole on the lower part of the axle. I was just too tired and did not want to screw it on that hole, used the spare screw and plastic ball area on the manual... i may return it to default position, having shocks angled way too much make the rig climb harder (at least thats what i experienced on my scx10 rigs)

Re: Akumu - bomber build
 

installed Proline Super Swamper (none xl's) and CWR-3002's on the new rig. spent 3 or 4 hrs just to get one tire fit on the china vanquish copy wheel... totally gave up on the 2nd because it was taking way longer. decided to mount them temporarily on the stock beadlock wheels.

Maybe i need to get the dual stage foams instead or get the swamper XL's... what do you guys suggest?

http://vlozity.net/akumu/bomber/akumu-bomber-06.png

as for the older rig, not sure what direction i am going with that... either i sell it or the yeti. still thinking about it.

I will do my first test run this sunday... hope all goes well.

thanks for viewing!

Re: Akumu - bomber build
 

Really cool looking pictures.

Re: Akumu - bomber build
 

I think those tires are a good size. The xls would be better for crawling, but be a little more tippy and the tires fold over more in high speed cornering. All prolines are a pain to mount. Some rims you can get proline specific inner rings for. Or get proline rims. Otherwise you'll be popping beads often. That's my experience anyways. I have the xls on my wraith. Really sharp looking rig.

Re: Akumu - bomber build
 

Thanks for the info! I was also considering the proline rims (wheels), but was opting for the one with the metal ring... then before pulling the trigger i noticed there was no hex wheel hub included and it was marked for yeti, that would mean I'd be using the stock hubs which has a tendency to strip. Anyways, i had a spare set of vanquish hex wheel hubs, just checked earlier and they are compatible, so i guess i will be getting those soon unless i get some funds to order from ebay a set of wheels that i think would be a great match for these tires and they are in black.

Thanks!

Re: Akumu - bomber build
 

Broke my links yesterday before even starting the actual event. User build error... did anyone post something about building the stock links on a bomber? I came from DIY building links back in the mid 2000's and always had issues with my set screws disengaging from the alloy links, so i always built links so that never came loose.

Btw, did I mention yesterday was a U4 event? hahaha The track was not really that hard but it did shake up the rig enough to loosen the ball ends and widen the ball end holes, which made it unusable.

So if anyone reads this, the links set screw is 20mm long, use 10mm for the alloy link and 10mm for the ball ends! :wink:

Re: Akumu - bomber build
 

rebuilt all the links, bashed heavily in the backyard... happy to report no more link issues :)

Re: Akumu - bomber build
 

Those Swampers look good on there.

Re: Akumu - bomber build
 

I've generally found that the more of the set screw that you can bury into the plastic ball end, the stronger the overall link will be. The plastic ends are the weakest point, and they always break beyond the point where the set screw is. The more set screw you have buried in the plastic, the stronger it is.

But you're still better off with Revo ends.

Re: Akumu - bomber build
 

@Jim85IROC, i learned the hardway... but it is now setup that way. the set screws actually do only go in about 10mm deep, going beyond that you may puncture the ball ends.

I will need to check the traxxas distro here, but my kit came from a distro very near my place (i get home delivery on a moped ehehe) and he was suggesting the rpm ball ends... unfortunately, he had no stocks now. This should work before those come in as backups.

Thanks!

Re: Akumu - bomber build
 

If you drill the hole all the way through to the ball end, you can bury the set screw all the way, which will make the end very strong. Keep in mind that this may require a longer set screw. You can also use it to snug a loose ball end to help get you out of the woods if need be.

Re: Akumu - bomber build
 

@Jim85IROC, that's sound advice and will keep that in mind when the time comes."thumbsup"

Re: Akumu - bomber build
 

the stock wheels did not really appeal much to me being plastic and all, i have a Yeti that had an upgraded wheel and installed that on the bomber. The servo also felt weak, being a generic China unknown brand, so I replaced that with an old Sanwa ERS962.

The ride height also bothered me a lot, went to the local distributor of Proline shcoks and wanted to get the Slash Powerstroke replcement dampers... unfortunately they where out of stock at the moment. Got scaler shocks for my SCX10 II insted :D

finally got to upgrade the motor mount, found a stash of vanquish parts for the yeti/bomber in an lhs... will be returning for more :)

problem is after i did the upgrade, the motor wont spin :( ... doing some troubleshooting now.

Re: Akumu - bomber build
 

started playing around with some 1mm carbon fiber sheets to make custom panels for the bomber. i think it's satisfactory, nothing over the top specially since i justed used scissors to cut the sheet and some sanding to make it clean.

now i just need to figure out how to do the hood. :D

http://vlozity.net/akumu/bomber/akumu-bomber-09.png

i've replaced the esc (thats the one that broke) with a Hobbywing 120A none waterproof esc. I just hope the coming comp does not have water hazards hehehe

thanks for viewing!

Re: Akumu - bomber build
 

What are you running for an esc/motor? You could waterproof the esc if needed. I waterproofed my 10bl120 fairly easily.

Re: Akumu - bomber build
 

I'm running the same hobbywing esc 10BL120. I never tried waterproofing, always got WP series esc's but was in a hurry because the competition is drawing near.

Got the esc used but almost prestine condition with a sensored hw 10.5t motor. but i opened to use my 2650kv unsesored 4 pole motor, our coming comp is more of a time attack/U4 variant.

Re: Akumu - bomber build
 

finally finished the custom carbon fiber panels...

Re: Akumu - bomber build
 

tried running the rig on a U4 style course with CI single stage closed foams and it just kept flipping over. hahahaha

made changes to the foams, 2 stage hack job while i wait for the CI 2 stages foams to arrive. also finally replaced the king shocks to some slash powerstrokes dampers.

http://vlozity.net/akumu/bomber/akumu-bomber-13.png

will test this rig tomorrow in a G6 style trail... hope it works with these temp foams.

Re: Akumu - bomber build
 

Nice build. Not sure if shortening the link on your sway bar would help any or not?

Re: Akumu - bomber build
 

@NitroBugg, Thanks!

i got the anti-swaybar from my 1st bomber (got it used) in this configuration, i think it is stock, I will need to double check. but i have not played around with it, my drifters when i started all had the same orientation, if i am not mistaken, and that was more than 10 years ago hehe

my initial run yesterday was good, still a little bouncy but the DIY foams are brand new and a bit stiff. ordering the crawler innovation 2 stage foam, but it will wait... holiday rush here is really bad, so I will be ordering them 1st thing next year.

Re: Akumu - bomber build
 

running on flat ground is not a problem with an unsensored motor/esc. the rig is so stable even in tight turns... i am loving it. would like to get it crawling one of this days but would like to replace the motor/esc to a sensored one before i do.

i am mostly bashing now, 2.2mah lipo battery gets eaten up pretty quick... need to get a high mah for it. :)

That's an excellent quality photograph of a very sexy Bomber, well done!

Looks mean and ready to dominate it's next U4 race...

Re: Akumu - bomber build
 

still working on the rear section...

no colored blinker lights in the rear yet, had this build on hold for weeks and have not even mounted the rad properly.

Re: Akumu - bomber build
 

geez... i missed to C3 events due to the servo running out of juice. at first i thought it was my 3S batter, i was using a 2.2mah, but it turns out that i needed to install a BEC.

got me a Castle 10amp BEC and did a bypass connection that powers the servo directly... perfect! now i am ready to go all out on the next event.

Re: Akumu - bomber build
 

what was the issue with the VP motor mount? how did you fix the motor not spinning?

Re: Akumu - bomber build
 

I did not get to fix it... the vanquish motor mount did not have issues. it turns out the esc died. just salvaged the motor and run paired with a Hobbywing 120Amp ESC but decided to use the sensored 10.5T motor to have more control crawling.

Love this rig... Class 3 is not so popular here, but i will push to get it mainstream this coming months.

Re: Akumu - bomber build
 

What are the wheels your running? I really like em.

Re: Akumu - bomber build
 

its a GPM beadlock... i like this too, it seems more aggresive looking to me that anything from vanquish or ssd and other brands. the thing is you need to use the stock plastic half of the wheel which has a tendency to strip. what i did was use vanquish slw wheel hubs, have not had issues yet.

Re: Akumu - bomber build
 

Thanks for sharing... it's got to be one of the coolest looking bombers I've ever seen!!! "thumbsup"

Re: Akumu - bomber build
 

This thing looks straight lean and mean! Nice build! "thumbsup"

Re: Akumu - bomber build
 

Thanks Guys!

I'm trying some new shoes, voodoo with 2 stage foams and SSD wheels (not a fan of this wheels... they are so plain looking).

http://vlozity.net/akumu/bomber/akumu-bomber-17.png

We are having another C3 comp on the 14th, this new setup should perform well... but still thinking if i need to put some weight on the front tire. still looking into that.

thanks for looking!

Re: Akumu - bomber build
 

changed a few things on the bomber, not sure if you noticed the previous changes... replaced the plastic rear shock tower with Boomracing Shock Tower With Strut Bar, also replaced the lower axle link connectors. Last week I got an Aluminum Front Offset Axle Link Mount from Boomracing.
