Questions Setting Up My Bomber that's Well Balanced

[Mayday!]

Just picked up a Bomber, super excited.



So What I'd like is to set up the Bomber so it has a good balance between crawling and rock ...... *sigh* racing.

Now let me paint a picture:
- My friend has a Twin Hammers he's done a couple of mods to fix the front end and ditch the cantilever setup.
- I LOVE how smooth it is over rough terrain, it just glades over gaps and absorbs most things in the way. But I do realize this is partly due to it's weight and due to the IFS
- The TH also crawls like crazy, the low CG makes it wonderful for a lot of smooth crawling
- Ultimately I like the Bomber a lot more, I was considering the Rock Rey but got a killer deal on the Bomber I couldn't pass up.


I typically do crawling and trails. I'm not super aggressive and I don't "bash" hard. But I like the idea of having the speed for fun in trails in that rock racing fashion. (There are no U4 tracks near me so I'm not even considering that)


First I know I need to watch the CG to keep the nose up, I was also considering a light rear sway bay, seems there are mixed opinions for this when using for crawling and I get why, so maybe a light sway will help.

What other suggestions might you have to balance?
- Suspension
- Weight
- CG
etc.

What about IFS, or is this just a waste of time/money?

Side notes:
- Ordered the Holmes hobby 550 motor for it, I think 27t. I figure this will allow for more torque application but still have speed.
- CI single stage foams (will get tires and new wheels later)
- Ordered links and a servo for it as well.

- I have a wraith that's dedicated 100% to slow crawling. It's been a fun build so far. Which is why I wanted something more balanced.

If you have a Wraith for slow crawling, get a 550 21T for the Bomber
Make it faster

Or skip the brushes and get a puller pro 3500, speed and crawling in one motor.

As for IFS, consider how sharp it will/won't turn. If you like the Yeti's character, give it some consideration. My IFS/IRS rig turns like a semi with the diffs locked, sucks that I have to get a 30 point turn, back and forth because it doesn't turn sharply with the slightest bit of traction, no bueno for serious crawling. Unlocked, an entirely different bird. I think the B1B guys do putty, offering a little give. Perhaps one of them will chime in. I will have the "luxury" (when/if I put the servos on them) to lock/unlock, you wouldn't with IFS. Realize you are going to have to settle as far as being "competent" in both areas you want to run, the suspension tune is drastically different between the two IMHO.

I know billinvic loves the B1B and B2B bombers, look for his build threads on these forums

You've just given me a really cool idea for ifs rigs, use a locked rear with a lockable front.

Are there kits for a lockable front, and for that matter converting to IFS.




If it's gonna cost too much maybe I should just consider hunting for a good deal on a Rock Rey.

 

[Jboucher]

Check out The DMG garage on Facebook, he sells kits for the bomber IFS conversion.

Pretty pricey

In my much less than expert experience with my Bomber.
Mamba X/ HH Puller Pro 3500 for power.
A rear sway bar is mandatory. It helps handling a lot and in my experience it will not crawl at all well without one.
Avoid week servo's as well. It's a false economy to cheap out here. After suffering much aggravation you will just end up buying twice .

 

[Mayday!]

Ok servo and motor, got it.


I will switch to the brushless motor/ESC down the road, it's simply too much money right now.



What about getting the CG lower and aft?
suspension changes (mount location, fluid, springs etc)

 

[Rumpelhardt]

If you climb steep hill's you will want the weight low and more forward.

 

[Jboucher]

Basically beef tubes in the axles and wheel weights or knuckle weights up front.
