The best way is from the bottom. And that is the way they will be built.
We looked at several different designs and everything was pointing to having them removed from the bottom.

I look to have them in production by the end of the week.

Also do you have any updates or price quotes yet Jamie?

| Hi, I was wondering what type of gears are used in the bulkless conversion. Would UE 8 gear spider diffs work? Thanks!

That is a good question, I will need to get back with you on that one.
The Savage has a larger ring gear than regular buggy gears so there will be a difference between the pinion and ring gear. Hopefully the difference can be made up with the pinion bearing.
I will check this out. And get back with you on what will need to be done.

| Ok, thanks! If they won't work correctly, are there any other strong diffs that could handle insane power that will fit?

Thats is awesome!! Many people are waiting to use buggy diffs in their savage especially the UE 8 spiders. In several forums, ppl every now and then keep asking about the UE diffs in the savage. From what ive researched, the only thing that need to be adjusted is the pinion bearing section. But I bet jamie knows alot better than me. Please let us know about this coz I bet ppl will grab the bulkless that will accept the 1/8th diffs. I will be the 1st one to buy the bulkless if they accept UE diffs . It will be a great product

Jamie hows the bulkless coming? The big north West hobby expo competion I am entering is febuary 4th and my truck needs bulkless. On my display I will have a piece of paper that says FLM products also so you might get some puiblicity "hint" "Hint".

Savage bulkless 80% done. I will be finishing up on the prototypes this evening. I will be test fitting them tomorrow along with sending out a set for test fitting.
They should be in production late Wednesday. I will be basically waiting for some feedback on the prototypes to make any necessary changes in the production pieces.
I do have some photos after the 2nd op if anyone has just gotta see them.
The cost looks to be around $120.00 for the full set. They will be sold individually though for $60.00.
By the way, just about any 1/8 scale gear will work. Provided you shim out the pinion bearing 1mm. I might even make a set for these gears? Depending on feedback.

Can you send a pic to nickthepyro@aol.com. Thanks, Nick. Also I will be picking me up a set ASAP.

Hi Gentlemen I’m Shawn I run 6 gear Ofna Spider diffs in my savage. They work well but there are some things you have to do to the Spiders. The JOINT CAP or Differential Shaft where the Dog bone goes in is too small on the Ofna Spider for the Savage dog bones, including the Hot Bodies Mega Travel Drive Shafts. On the Ofna diff shaft the size of hole for the end of the dog bone of an axel is 8.03mm. On the HPI Savage diff shaft end for the dog bone end of an axel is 9.12mm.
You have to swap out the diff ends. Now here is the issue. The length on the shaft that enters the diff it self to hold the bevel gear and pin, is not the same on the Ofna ends. The savage ends are also longer. 14.73mm on the Ofna ends and 15.50 on the HPI Savage ends. This causes slop in the dif because the pin hole on the shaft of the Ofna diff end is 8.65mm from the back side where the bearing is. On the HPI Savage diff end the pin hole is 9.50mm from the back side where the bearing sits. But when put in the diff case it seems ok my mesh on the ring and pinion gears do not seem to change. But you can pull the diff ends out a little. I use 2 rubber rings to hold my dog bone close for little slop. Now if you use plastic diff cases this will flex with super power plat engines. I recommend Alloy Front and Rear Gear Box’s. If you’re using hipeformence engines so your diff does not get any distortion on the gear mesh.
I used the existing Savage Bevel Gear 13 Tooth with 3 8x10.3x.12 spacer rings on the gear side not axel side for gear mesh.
Now the ring gear or Bevel Gear 43 tooth yes is smaller on the Ofna diff then the HPI Bevel Gear 43 tooth. This causes the Pinion gear or Bevel Gear 13 tooth to ware out. But the handling got better handling on the track and I got better rock climbing with 10000 diff lube instead of lockers.
I have not tried to use a pinion gear form OFna yet I need to.
The reason for me trying the spider diff was because even the 4 gear was warring out so fast. I never really had problems with the ring and pinion gears but now using the spiders I no longer have my 6 gears warring out but the pinion gear does. I will look into researching the Ofna pinion gars setup and let you know. My Savage is under complete re construction right now. It’s torn down for my new Fastlane Machine Extended Low Center of Gravity TVP, Adjustable Shock Towers, Adjustable Upper Control Arms, Extended Arm Conversion, Servo Plate Kit, Center Skid Plate, and Servo Mounts to all show up. I just placed the order but once it all shows up, I can get back to bashing and I will do some more investigation on the Ofna Spider diff set up for my Savage and let you know the result whether its worth all the work and money. Right now it’s 50/50 I do like the hook up at the track.

Via Matt,
Basically, these are the "Class A" units. This are the basic Bulkless System, however in early 2006, we will be releasing our Class B units, which will be for the racers, who need the Diff to drop out easily!
So what is the difference between the Class A, and B? Well the Class A are built to be bashed, and bashed hard! They are built solid, and are bulletproof! You will however have to take it off the Truck to change the Diff.
The "Class B" units will have two blocks that drop out from the bottom of the Diff Housing, that will allow the diff Bearings to slide out from the bottom. The design on these is still very much in R&D, so that design might be revised quite a bit.

That is a looonng post.dThanks man.. Ok here is what Ive gathered, to eliminate the problems u have just state, u can use the Unlimited engineering drive cups, the size is almost the same as the HPI drive cups and it can be used in OFNA gears coz UE designed the drivecups for the OFNA diffs. The real problem is just the pinion bearing section as Jamie explained.
Jamie, you are right about shimming the UE 1/8 diffs pinion. But it will be about 1.8mm of shimming and that will keep the pinion less supported by the bearings. So what Im thinking is, maybe u can adjust the bearing section by 1.8mm towards the ring gear (diffs). That will keep the pinion supported nicely. But that is just what Im thinking, maybe u have better solution for this. And if you need someone to test the "hybrid" bulkless, Im willing to pay for that. I mean, I'll buy that prototype and I'll let you know how the bulkless hold up. If you have hybrid bulkless for maxx, why not for a Savage. I bet alot of ppl are waiting for this hybrid bulkless.

Thanks for the info. I have them on order today. I will be pre ordering the Bulkless system for my savage soon as Atom Rc hooks that up.
So I to will let you all know how that works out.

I used the existing Savage Bevel Gear 13 Tooth
the reason for its wear, is because the 1/8th ofna 43 ringgear is helical cut, that savage gears are a straight cut. Combining them is not an option in my opinion. it will wear for sure.
@ admin;
perhaps it is an idea, to place the bearings a bit closer to eachother (bearing that hold the pinion) which would make it easier to get more grip with the input cup on that shaft. (that is the problem with shimming them too tight inside the original savage cups) So my guess is that if you used the same sizes, that the 1/8th diffs will suffer the same problems in the bulkless.

That does look like a good idea, I do not see any issues with it like that.
The bulkless are now in production, release should be Friday or Monday depending on when they get done. I will have a good pic up of them when they are complete. Although I may take a shot of the prototype ASAP.

| Referring to the idea of the "hybrid bulkless" that will accept the UE 8 spyder diffs, Jamie, since we are moving the pinion bearing section towards the ring gear, they might be problem with the length of the front center drive shaft. It will be 1.8mm shorter coz we'll move the drive cup towards the ring gear. So maybe you can offer us an extended drive shaft. Matt told us at Savage-central that FLM has a very strong material for the drive shaft. And can you let us know when will the type B bulkless, for racing will be available? Thanks!
