1/6th Scale Savage Conversion

Lol, yeah I cut a little slot for the spur. I wasn't going to post it, but the plate had a funny wtf face by the time I was done.



So I got the paper template laid out @+110mm. I laid down the bulkheads, servo and motor/cd to get a rough idea on the layout.





Even with the extra length. its still going to be pretty tight to get everything within the tvps. One bog challenge is going to be how to arrange the batts. Basically I got a few ideas. Easiest would be to make a batt box above the F driveshaft. It will sit pretty high tho. 2nd idea is to make saddle packs alongside the driveshaft, and fit them low in pockets. I was planning on HV anyway, so having twin packs is likely.

The 3rd option is to lay the packs flat and low and build batt boxes to open outside the tvps, sorta e-revo style. Its a bit sacrilegious, and I'm not that thrilled about having to make secure doors to hold the batts. OTOH, it would give the best cg result. Eh.



The first option is the easiest, and with that CC motor sale, I have a very cheap 1717 and 1520 to play with. Its awfully tempting to just use those on 6S or so w/ the MMM. Plenty of power and performance with parts already on hand. Otherwise I'm waiting still for the HVMMM, and who knows when that's done, plus its more money to spend...


I did look thru your pix _dV. You had some great ideas and layout. I like what you did with the str servos. That was another thing I was debating, how to mount the servos, as along the rail, the serov horn comes v close to the motor in the rear. I was going to turn them perpendicular to the tvps to clear more space for batts, but I may steal that idea if it doesn't work out well. Need to do it F and R, and its tight in back.

Had some more time to work today. Baby daughter has been sick, so had some time to work while she napped today. Got the tvp template transferred onto the pressboard, then cut it out with my bandsaw. Made quick work of it.

I doubled up two boards and screwed them together with the paper template screwed and taped in. Ended up needing minimal trimming to fit, mostly around the upper bulkhead connection.







Pulled the other tvp off the XL, and just bolted everything onto the new tvps.





So its not massive, but def bigger. Could use a bit of widening tho. 1" per side would be awesome, but parts just not there. I know FLM has a .5" widening kit, but its $$$, only 0.5", and alu.

Hopefully the MBX6T parts come soon and everything works w/o too much of a pita. We'll see.

Steal away if it's gonna help. It's a pretty simple mod and the cutout for it is bridged by the steering post behind it so the TVP structure isn't really compromised. I haven't had anything hit\damage the exposed steering in a decent amount of varied driving either, the location makes that unlikely i think.

Will be great to see some vid of it when finished. I enjoyed watching the vid of your previous 4WS build and its unusual look when turning.

Btw, you might find that with the cutout you have for the slipper that rocks will get stuck under the adjustment ring as its diameter is much larger that of a normal center diff case. That's why my cutout is as wide as it is.

Thanks for the tips. :) The little platform is just a temporary solution just for fitting purposes. I'll be sure to cut the final plate larger if/when I actually get to that point!

I'm glad you liked the vid. It was pretty short and crummy, but just something to show the 4ws in action. Meant to make another vid, but have barely drove it this yr.

I made a better template using acrobat. The one attached earlier is handdrawn and scanned. This one I added lines digitally to be sure they are square and they print darkly. You have to tell the printer to print comments for the lines to print. Kinda lame, but Adobe is teh ghey.

I may end up cutting another template with a shorter wheelbase. The bug body I want is really suited for 480mm wb and I'm worried it may be too long to look right, but IDK at this point. Since I may bail on the batts inside the tvps, there is not much point to the bit extra length.

Prolly buy the body and compare the two templates before I make any cuts into my alu stock tho.
