Hot Racing MOA rig (2.2)

[renoirbud]

I had some HR axles sitting in the shop and some ideas. I made a low CG Servo mount, added Berg top 4link mounts.

I designed a chassis today that looks good and works better then anything I have ever run before. This is the first crawler that I have had that handles better then Tuber I used to qualify for 2007 nats, since then nothing has felt near this good. With Losi Claws, and no dig, i was able to get up ledges that I was not able to do with Panthers on my Berg Builds.

This chassis is an absolute home run, I will have to make a couple of these to sell, it will work with Bergs and Hot Racing axles.

I will post a picture tomorrow, the truck is bent right now because I stripped a ball end trying to clear a gap.

Parts so far

- HS5995 TG Servo (not the HS5955)
- RC Innovations Delrin Chassis
- Low CG Servo mount
- ST Racing bent Links
- RC4wd Beadlocks
- Proline Mem foams
- Losi Claws
- CC BEC
- CC Mamba Max
- Lathe motors
- Berg gears and spool
- 11.1 V 1500 MAH Lipo
- DX-3r

It will have dig, I am waiting for a package from Holmes for HD dig switches. I will activate them with a HS81.

[Shocker]

Very interested in the low COG servo mount. I'm waiting on one from Culetto but definately wanna see what you came up with too.

LMAO, you guys suck, I will go and see where my camera is.

D@mn yall crackin' the whip pretty hard tonight :p


That is a tiny pic though. I could see the tires real good. ;)

[renoirbud]

You guys are funny, I was just looking for the best hosting service.

[renoirbud]

I will do a roof, hood and sides for it tomorrow. I am sure it will look sharp, this one is going to be mostly black and chrome.

The top links in the front are not up to my abuse, I will replace them tomorrow too.

[rockshow]

It looks much better!

I think that it is safe to say that Rene went into an 'I do not give a SH!T about RC funk' after nationals. I spent quality time with the wife and worked on my 1:1, mountain biked and did some other stuff.

I am now completely out that phase and am ready to have some fun again.

When I have time to cut and paint some panels for this truck, it is going to be ULTRA sharp. (and it floats up lines that I have never been able to do)

Hey there the rear axle is the same as I had at the last comp, I just put different wheels on it for testing. (I sold Berg Axles, the DNA Snipers I had and am selling the Stalkers)

My Shafty may get close to 88 mph, I am sure it will be entertaining. (scale speed LOL)

I am switching to a Castle Creations 1/10th Side Winder, it might be easier to pit on the back axle, or maybe it even fits up front somewhere. And it is 8.5 grams lighter.

I figure there will be about 5 guys(alot) that are gonna be the one's to gun for. At least for me that is. I'm sure a couple of wildcards will get thrown in there too along the way.

Growing like gangbusters no doubt.

I am thrilled that the club is getting stronger. I really hope this continues. I think the results achieved in Va are just great, but Va is just a newer club, they will improve too.

I would love for the North Carolina Boys to travel to big events like the East Coast Championship and take a bunch of the top 10 spots. It would be great if we can turn into a force like the SERCRC is. I think we are on our way to get this done.

He should be limited to running only 3 wheels.

[renoirbud]

I am working on Version 2, I changed the link length on the top links, and I will raise the cab to make it easier to get back onto its wheels. The mounts for all legal panels are already shown.

The name is

2.2 Lucky MOA

[renoirbud]

The geometry is the same changes are;
- Shock mount braces are stronger
- Entire chassis is beefier
- Legal size body panels are a direct fit
- Cab is higher with rolled fastback, will make it easier to get it off it roof

[renoirbud]

I took the time to detail my part drawing (add material type, density, etc..) and used the mass function and found the last drawing to be too heavy.

I am going to try to break my tester today so I can find the weakest spot. Then this design is going on a diet. It should be able to reduce the amount of material by 40% without adding machining time, nor effecting strength.

And the good thing is, I can do that while I am in hotel in Ohio (then Memphis) next week.

[renoirbud]

New and Improved now 30% lighter!!

The curved top was initially not used, because I do not like the way it looks, however, it is too hard to get the bodypanels to fit well the way I had the design before.

Seeing Elements curved roof (on one of his prototypes) made me decide to give it a try again.

This version I will use at a comp. I do have two ideas to make it better. One to make it easier to adjust the ride hight. The other to make it easier to mount a lower body panel. But that can wait.

Having 3D CAD really helps me build a better chassis. It makes it easy to develope a design, rather then start over every time.

I think you on to somthing there Rene

[renoirbud]

Hey Tom

I know you prefer edges and corners, but the smooth curves are there for function. Plus it is also way easier to fit body panels when you do not have to make sure that two creases are an exact distance appart (I know you can make a jig, but who has time for that).

I am very please with how this truck drives and I am equally proud of how it looks. I am also thrilled that it is a completely unique way of using delrin to build a chassis.

[renoirbud]

I took the new truck to Vacor event #2. The chassis out performed the pack by a significant margin.

Did it surprise me? Yes, I finished course one in 90 seconds with a single reverse. That surprised me.

About running against many others, we will cross that bridge next weekend. There will be a large crowd, including some very well known and very good drivers there.

I also expect that Mike and Silas will bring their 'A' game to this next comp.

It should also be know that Rene went up the night before and stayed in a 'Holiday Inn Express'.

Good Luck guys. I'm sure you will make us "proud".

I hate that my rig is not ready to go yet.

[renoirbud]

I really hope we all do well at the next comp. It looks like it might be a wet comp. I am testing some M2 Hammers tonight, to see if I like them better in the wet then the Panthers.

I already know that I hate the Hot Bodies in the wet.

[renoirbud]

I was able to do some testing at the GA event that showed me that my squat/anti-squat angles are good if not great. But I am running a fairly low powerred rig. I am entertaining the idea of running some faster motors, just to be able to do a couple fancier tricks. This may cause the geometry of this rig to not work as well.

I will redesign the lower and upper sides slightly in the next couple days to give 3 or more mounting positions for the top links, also the top link mounts will not share the mounting hole for the side panel.

[renoirbud]

Lucky just got adjustable;

http://img.photobucket.com/albums/v243/renoirbud/v5adjustable.jpg

- Lower links are fixed
- uper links can be moved to 4 different locations in the front and 5 in the back, making 20 different squat angles possible
- shock mounts can be raised and lowered by droping down chassis center in 4 different heights and can be moved backwards and forward in 5 position so 20 different possible shock mounting positions

The mass is basically the same and lateral stiffness is increased.

[renoirbud]

I am breaking axles everytime I run, and I think the issues is that my servo can turn the wheels too far and they get bound up.

I am going to tap and drill some hard stops into the steering system to prevent this.


I loved the functionality of the new servo plate I had today and that it protected the servo from breaking off the mounts when the truck was up side down. If I have time I am making a mount the goes behind the axle so that the tie rod can be brought closser to the servo for more power. I obviously have more then enough throw.

[Silas]

It sucks that you keep breaking axles... hope that its the servo throw and it fixes it.

[Blueridge72]

The stops sound like a good Idea. I had that same problem. When I went to high clearance knuckles, I snapped 3 plastic C's in less than an hour before I figured out what was going on. You don't waste any time coming up with improvements do you. :)

hey rene what if u shaved ya axle stups also i did that on my ax-10 because it was also binding and it fixxed

[renoirbud]

hey rene what if u shaved ya axle stups also i did that on my ax-10 because it was also binding and it fixxed

I will look at that, but I can steer to the point where the axle pin only engaes one side. This might get worse if I shave the stubs.

[renoirbud]

The steering limiter worked. I was hard on the truck at the last comp and had no failures. This makes me very happy.

Your clod axles will look at you when you cut the power on and say... "Nuh-uh!" And then implode.

I think a super on 22.2V and two 45t singles will be able to do some sweet jumps. I hope its fast enough to clear the double.on my track.

The Title of this thread says, "Hot Racing MOA rig (2.2). Now we have a shortcourse Super! lol!

[renoirbud]

This truck has Berg axles now and I put in the Cobalts, wow. The power is insane, they are way faster then my 45 t lathe motors and the start up is good. They stayed totally cool through two packs (1320 Mah 2 cell), but they eat Mah like crazy. I think if I use the HR gears so that I can gear for more torque, they will be perfect. I am just not willing to take a chance on them without more testing.

I will be running Holmes Torque Master motors at worlds.

[renoirbud]

I just can not get a steering set up the way I like it. This is really pissing me off. I am firing up solid works now, I will have something before I leave on Tuesday for Crawlapalosa (I even passed on bike ride to day because this is bugging me)

Plan
1-low CG servo mount- move upper link, horn facing back

2-make highsteer knuckles that work with 300CVDs

2-tie rod for over the top, likely delrin with brass sleeves

[renoirbud]

off to the mill I go!

http://img.photobucket.com/albums/v243/renoirbud/knuckle.jpg

I will make these out of Delrin, I do not have any aluminum here right now

[CRSMacgyver]

Wanna make a couple extras....lol

[renoirbud]

I am moving the Tie rod ends in by 2mm, to give the tire more room and making the arms a liyyle beefier. Th top king pins will also be a little different.

[renoirbud]

I have run out of time to make my own high clearence knuckles. I am lucky enough to have CKRC knuckles. They are 0.4mm widder then the Bergs, that should be fine for the CVDs.

The AX-10 knuckles put the CVDs 1.0 mm to the inside, therefore mis-alligning the kingpins and the cvd.

[renoirbud]

here is some progress
