Gearing time!!!

So I plan to use the 1717 motor. Got it to fit perfectly on an old flm electric motor mount, the one designed to bolt to a nitro savage motor plate. Thats right, no cutting or anything, bolts right on and just touches the bottom of the bracket, no flex!!! I do not see this part on flm anymore, but I will take pics for you guys!

Plan to use a 47t steel spur and a 16t rcm pinion. I have enough room to fit that without the pinion contacting with the side of the tvp, and there is enough sliding adjustment in the nitro motor plate to get good mesh.

Now with that gearing and a std flux tranny this thing would be slow. So I just picked up the 39t idler kit. Basically the flux is locked in 1st gear (old savvy 2sp nitro tranny) and the 39t idler kit locks it in 2nd gear, 1.54:1 reduction. That with the 29/9 of the bullet proof diffs should give me right around 45mph with 6.5" tall tires.

Also bought the HD input gear cluster for the flux, as those wear from what I have heard. Keep in mind my only other savage was a 25 with a 14xl on 8s lipo with a 2sp and mech brakes. Never could keep a diff in it for long.

Thoughts? Not going to be a 5t but it will be a big bad MT...

What's all this talk about CC 2080, 2026? Where can I read up on these motors? I could only find the 2028 one.

I guess we all mean the same motor... The 2028.

Here are some pics, enjoy.

You can see how the atomic hubs fit, need a few shims to get the slack out. Bearings fit well so i guess I cannot complain.

Looking forward to seeing this built completed. I wonder, how big is the 5t chassis compared to the DB-176DB 17 has a wheelbase of 448mm (17.6 inches.)

Also, I currently have the stock hubs on a Flux of mine, and the rear, as well as the front obviously, have turnbuckles? Do you need to get aftemarket ones in order to remove the need for turnbuckles? I see that yours are in a set position. I didn't realise this before earlier..

These eliminate the rear turnbuckles:

Have those coming as well. Ordered them a few days ago.

This chassis, which is not the savage 5t chassis as I found out yesterday even though the guy who sold it to me said it was...

Wheelbase here is 19", so the redcat rampage 5th scale body should fit it just fine. I will have to order one and see how the width looks, may have to go with the XL axles to get the width to look right.

The hubs that vortex linked will eliminate the rear turnbuckles, and they look just like the atomic ones I have pictured above.

Have you actually read any of the forum posts?!!! There are three or four builds of 5T conversion at very least.

5T is 22.4" wheelbase; most of the "5T" conversion the same wheelbase. Mine is going to be about 22" when I convert to center diff just because of the dogbone lengths I can get easily.

Yeah, I thought this was a 5t length tvp setup, but it is not. I have no idea where it came from, looks to have been made by a large stamping machine so it is not likely a one off. But it is not long enough to be the hpi savage 5t chassis, and it does not quite look like it either. Not hand made that is for sure.

Anyone have a list of stretched tvps made by ?

Probably yes. Although watch out for breaking the axles where the threads begin, especially with the heavier vehicle and wheels. Check my thread for what I had done to use 24mm Baja hubs on Savage XL axles.

Or you could convert to using truggy suspensions instead of Savage too. Jamie @ FLM said he is working on 17mm-24mm adapters, so we'll see. If he comes out with them I may try and switch to using truggy arms.

If I was going to do something I would make lower arms that would mount to the savage and accept lsts hub carriers. Lst wheel cvds are longer than savage dogbones. Plus they have 8mm truggy style axles, and just about any hex adapter will fit. I will have to compare them and see what kind of with difference to expect. I know people go with CEN cvds and arms, those are wider.

The CEN Gensis?

Why not just use the lower arms from the XXL? Just need to probably remove some material from the bulkhead.

I checked the wheel driveshaft length on the lst2, not much more than 1/4" more in length so not worth the time.

Yes, I have seen people use the big cen genesis arms and driveshafts on the savage.

Here are a few pics with wheels on. I got measurements for the Redcat rampage body and it is 10.25" wide. So I think at 18" width now it will look a bit too narrow. Does anyone know how much wider the xl axles make the truck? Look at the pics it does not look like 1/2" per side, maybe less than that?

Just looking at my own pics, think the chassis could use a brace where the material was removed for motor clearance. Something like an upside down U that bolts in front and behind the motor and goes over the top of it.

Very poorly done pic, just to give an idea of what I am suggesting:
