Future: Brushless 1/8 Buggy *CAD Renderings*

Hey MaXXler, glad you could be part of this. I would like to see pics of the new project once you get to it. Let me know any advice if you have any. Also, I wasnt a huge fan of the razorback. I was waiting for the G3 to come out but it just doesnt look like it is going to makes it's way out.


I need to still order the XB8 steering assembly, but I am just going to CAD with the stock Ofna 9.5 Suspension.

Good job so far. When you render it, though, make sure to click perspective on. It does wonders. I'm looking forward to seeing the suspension and steering modelled.

Before I go anywhere from here, I need a solution to a problem. A member from another forum brought up an issue about the motor braking with a center diff will only give breaking to the wheels with the least amount of traction and usually spin out the buggy. I was wondering if anyone had a suggestion for a fix to this problem without running mechanical brakes?

[squeeforever]

Your only options are:

A. Mechanical brakes, front, rear, or front/rear
B. Run a one-way in the front so only the rear have brakes
C. Don't believe him

I wouldn't think it to be a big deal. 90% of conversions use the motor brakes and I have yet to here somebody say something to that effect. Infact, I have a LSP that uses motor brakes and it doesn't...It stops on a dime however...

Update*

Thanks squee, I think I will just give it a try, and if there are problems to worry about them later.

I am messing around with the idea of widening the chassis to allow the center diff with a 46t Kyosho plastic spur to fit between the lipolys packs allowing me to move the diff to the center more for a better balanced vehicle. I also threw in a render of the motor slightly off to the side of the diff, this would drop the COG, but I am wondering if the motor heat will transfere to the lipolys packs this way even if I have my battery hold downs/heatsinks on?

There shouldn't be any problems with the motor right over the battery. Personally, the motor shouldn't get hot enough to worry about anyway...Are you going for a buggy length wheelbase?

[glassdoctor]

If there were horrible braking problems as this person suggested then it would be a big topic. He doesn't know what he is talking about... obviously he's just speculating.

As I have said before on this topic, I have no problems with "electric" brakes. It is different than "nitro" brakes and there are disadvantages, but it's not a big deal. You can't use the brake to help the car rotate like with mech front/rear bias brakes. But there is no spin-out problems... the only bad thing with motor brake is that the front tends to push when hard on the brakes.

So you may have to brake a bit earlier and roll the corner or be on power through the turn, compared to a nitro.

I am going for buggy wheelbase. With this new chassis layout, I am able to move the lipolys back even further which is giving me more room for the stearing assembly from the XB8.

What about putting the motor in the center down on the chassis with the center diff above the motor. That would lower the COG. I had thought of that when I was laying mine out. I was able to keep everything down on the chassis with a different design. I used only one battery though. It could be off to the side and above one of the batteries. The drive shaft angles should work fine. I had mine mocked up like that and it looked like it would work all right.

that just looks plain SICK! i really want one now lol darn u! but id say for brakes, i have a mini inferno and it has a center diff with gears and nothing more, so no oil or anything and when i jam the gas it unloads, but jam the brakes and all 4 wheels would be stopping... id think the same here, past that just use heavier wt oil if it does happen lol.....but what other cars could u do this for? id want a truggy like this, lol every time i look at it im like I NEED THAT!

Changing up the design for a truggy application would be very easy.

Silentmonster, I really dont think that setup would work in my situation.

Update*
I should have a few new renderings in a little while.

id like to use losi 8ght t stuff....if u could make that all work that would be sick! but im nt asking for anything now lol, looks very pricey to machine all that:eek:

I would never choose the 8T suspension. They don't handle as well as alot of truggies, mostly because there very "twitchy" from what I have heard, but they say if you get use to it (not easy), you can be pretty fast with it. Anywho, I would go with the Mugen MBX5T suspension.

well personally, ur the only person that has said that... all the ppl i know have 8ghts and race at there tracks, and the fast truggies are the 8ght t.... i would use it i like it and thats what matters

[squeeforever]

Like I said, I have heard from numberous people that they prefer the Mugens because the 8T is twitchy, or "very responsive." I'm just saying, the Mugen is a better handling truggy.
