Didn't the brake kit come with the correct hex? Looks good Linc. The mount should do the trick as long as it doesn't allow too much flex. I assume the motor sits on the bottom plate so it should be plenty strong enough. I'm surprised there aren't more mounts like that mount too but mikes revo mount is fairly similar.

Nope, but the hex that the ss kit looks good, and I think the lhs has one in stock.

The motor does sit on the mount, and I plan to put a rcm heatsink on there too, so there should not be much flex. Maybe I should make some more, or get the local machinist to turn out a few. Mine is a bit rough for resale, but a nicely macined one would be good. For the best gearing options it has to be as thin as possible, to keep it close to the stock motor mount plate.

That's strange cause I have bought 2 kits with the same part number as the tower one you posted and they should come with the hex. That's the challenge with the savage as it does need to be as thin as possible.

Strange, I just checked both pics and they do show the hex. I may have to look again on the bench, but I am sure that it was not in the bag. I will look tomorrow, and if not the lhs is open on tuesday. Monday's suck, so I may have to work on the truck later in the week. And I really need to clean my table up before another project, it is a mess!

And you also need to snap a picture or two of your bench and storage of your 20+ rc cars. :yes: :mdr:

Yep, I really need to finish orgaizing the r/c workshop so it is clean enough to take pics.

Thanks, I'll be watching the thread. got my savage ss last night. next payday I am ordering the flm kit... should be able to order the monster max too to drop in... too many toys and too many lipos to buy is slowing production (just finished an 18B brushless buggy and working on a mlst)

Ok, made an esc mount, cleaned up the wiring, and took it for another test run. Plenty of power, and it will wheely all the way thru 2nd gear. The great planes esc is very controllable, and even starts up very well. If full throttle is pulled from a standstill the motor starts, slowly for a second and then full throttle. It does not do this when the truck is moving, throttle control is immediate when the truck is rolling. Motor got a bit hot for my tastes, but I do have a spare rcm heasink clamp, so I will give that a try. batteries and esc did not get much more than warm.

Sorry, no pics as the camera battery crapped out today, but I will try tomorrow.

So I gave it another run tonight. Stopped about 10mins in to replace the crap stock steering servo saver with a 1/8 scale type of servo saver. I used the HPI kit, as the lhs had it and it was fairly cheap. Big difference, and I am still using the stock steering servo. I have a hitec 5997 to put in, but I wanted to see the difference that the better servo saver design would make.

Had my buddy radar it, 41-43 mph at best. We also built some jumps and beat the truck a bit. Nothing broke, and I would say that I got at least 30 mins of mixed bashing. This is with the polyrc 3600 12c cells, 8 in series. I have a pair of flightpower 3700 25c 4s packs to get from the lhs. That should allow me to gear up to a 16t pinion from the 14t.

Temps were good, batteries and esc were warm, the motor was hot, but not as hot as the last run. I found that the slipper was set too loose, and was letting the motor spin up almost unloaded. I tightened it up, too much actually. I was doing backflips if not careful! I adjusted the slipper a bit and got it where it needed to be.

I do need to install the twin disk brakes, and have the hex at the lhs. I have a single disk at the moment, and it just does not have the power to stop this truck the way I want. I also put a wheely bar on it, a must IMO!

Still need to get some pics, but I may wait until I get the wiring finalized. I am still looking for a cheap bec that can handle 10s lipo. Hobby City have a turnigy bec that looks good, and is 20 bucks. I need some other stuff from them, so I may order a couple to test out.

What servo saver did it have on it and what saver have you changed too? I have been wanting to upgrade mine but haven't looked into it yet. Good to hear that it runs well and you really need to get some pics linc. No one really cares about the wiring.

Haha looks familiar, heres my bro's solution for a savage conversion, including twin outrigger battery trays. Good having it clamped like that, though gearing is somewhat limited - no problem unless your aiming to break any world speed records.

It had a stock servo mounted saver. I replaced it with this: http://www3.towerhobbies.com/cgi-bin...?&I=LXJSS6&P=V

Night and day difference, much better. I will upgrade the servo too, and this kit comes with all of the different adapters to fit all of the servos.

More progress
 
Got my Hobby city order in a few days ago, with the hv becs!

Bought two of these: http://www.hobbycity.com/hobbycity/s...idProduct=6320

Wired one up to the savage and it works great, no interference, and it even has an on/off switch. It is not small, and has a ferrite ring (big one) mounted about halfway along the rec wire. That righ is almost as big as a ccbec, and the main part of the bec is easily twice as big as a ccbec!

Other updates to the truck are a new steering servo, hitec 5997tg, and i relocated the rec to the area in front of the servos. Also added the twin disk brake setup, HD center cvds, and rebuilt the front diff to a 4 spider design. Also added a rcm heatsink to the motor, and put a set of 17mm hexes and some pin style tires.

Still running the 2 4s 3600 packs, and they work fine. Bashed it hard today, and 20mins later had a 2wd truck! Something completely let go in the front diff.

It was a blast though, tons of power. I was jumping it off the side of a ditch that runs down the middle of my grassy bash area. Got at lest 6ft of air and the truck flew well on power. I will open up the front diff and have a look at it, may be time for some al diff cups! The hpi ss ones with the steel inserts look good, I will have to try them out!
