This instead of FLM conversion?
 
http://www.neweramodels.com/item.cgi...=&part_id=3372
i realize it would take some fabbing for batt and motor and esc mounts, but this thing is HUGE! maybe i should get a set of savage axles off of ebay. maybe a mega 22/45/2 and a sentilon 100a esc on 10s to 12s? maybe the zippy-r packs? what do you guys think?

lincpimp 02.24.2008 01:14 PM

Go with the flm kit, much better IMO, plus it has the motor mount and battery tray already setup. I would post some pics, but I am waiting till I get it complete

BL_RV0 02.24.2008 01:16 PM

well, i would like to run 10s most likely and you cant fit that in the flm kit..... :no:

jhautz 02.24.2008 01:31 PM

I can fit 5s 8000mah truerc pack in mine. They are made from 4000mah cells in a 5s2p configuration. So you should be able to fit 10s 4000mah.
Dont get me wrong... Its a tight squeeze, but they do fit nicely.

BL_RV0 02.24.2008 01:39 PM

what would be the best manufacturer that makes a 10s pack that i could fit in there?

lincpimp 02.24.2008 01:43 PM

I would buy a pair of 5s packs and run them in series. Maybe some flightpower lipos, like the 3700 cells.

jhautz 02.24.2008 01:47 PM

I don't think you will find a whole lot of options on factory built 10s packs. You will probably be better off going with 2x 5s packs wired in series. You could just put another layer of heatshrink over the 2 packs to tie them together and you can handle them like 1 pack.

ANother thing to think about is charging a 10s pack. There arent alot of chargers out there that charge 10s well. 2x 5s packs might be asier to handle in this regard also.

EDIT: Pimp is a faster tyepr then me.....:tongue:

A pair of these might be a nice low cost option. And should fit nicely. I have 3 of the 5000mah 4s packs and they are great for the cash.

BL_RV0 02.24.2008 01:51 PM

well, the mega motor im using only pulls 60a, and lutach said he got 23 mins runtime with some 2200 packs on the 22/30/2 which pulls 70a. he was running 6s. well im thinking about the 2500 fp's 25c or the 3300 30c.

BL_RV0 02.24.2008 01:53 PM

no worries about charging, i have a 1210i.

BL_RV0 02.24.2008 01:57 PM

how about 2 of these in series?

t-maxxracer32 02.24.2008 01:59 PM

damn that is one extended chassis.

way too long imo.

BL_RV0 02.24.2008 01:59 PM

yeah, ill just get the FLM with nemesis wheels.

I dont see why that wouldnt work. Slightly easier to fit also with the 45mm width vs the 50mm width of the 4000 packs.

BL_RV0 02.24.2008 02:12 PM

any motor suggestions? i will probably use the mega bur i want to know is theres anything else out there that will work without breakin the pig!

Hmm, where did you get that idea!

I will take some pics of the savage with the cen wheels when they come in, should be next week.

I was going to run a 14xl on 8s lipo thru a cchv85 esc. Now I just received the 36/38/2 aveox motor (1200kv) and I think I will use that instead. The mega should be a good motor for this application.

jhautz 02.24.2008 02:21 PM

I will caution not going with any wider (diameter) of a motor than you need to. The motor diameter plays into how big of a battery you can fit. The 36mm can motors give you the most room. The neus and neus with fins give you less room.

BL_RV0 02.24.2008 02:21 PM

will it be enough power?
i do admit i stole your idea, but it is such a good idea, i cant resist. btw, ill use the 3spd tranny, in case that brings any problems to mind.

captain harlock 02.24.2008 02:40 PM

Just an input to the NEM chassis conversion.

A major change should be also applied to the spur gear.

The Mod1 spur gears used in the Savage will not tolerate the force used to move a Savage that's 5" longer than the normal truck.

I believe the spur will get stripped under pressure in a very short while.

cart213 02.24.2008 03:03 PM

The SS Savages use steel spurs. Surely those wouldn't strip out. I assume you're referring to the plastic spurs?

t-maxxracer32 02.24.2008 03:36 PM

ya know... ive heard people talk bad about steel spur steel pinion but i run it on my xt8 and LOVE it.

sure its a little louder but ive had so many times when the motor gets knocked loose and theres HORRIBLE mesh. but no strippage:intello:

i dont think ill go to plastic/steel or anything else.

BL_RV0 02.24.2008 03:45 PM

well, heres what i got with 49/12 gearing (cant find a spur bigger than 49t for the savage x model, i will be buying the x ss kit w/o engine)
Differential Ratio: 3.3076923076923075
Transmission Ratio: 1.5833333333333332

Total Ratio: 20.69531 : 1
Tire Circumference (inches): 23.56 inches (598.47 mm)
Total Motor Speed: 51060 RPM
Vehicle Speed: 55.05 mph (88.43 km/h)

i always thought a 20lb truck at 55mph would be cool.... especially hearing it shift into 3rd..... mmmmm..... hopefully flip over wheelies in 1st.

t-maxxracer32 02.24.2008 05:53 PM

it may not actually do 55 thats just in theory.

if you do let it hit 55 please get a video of it crashing:lol::lol:

BL_RV0 02.24.2008 05:54 PM

will do. what motor do you guys think the 45/2 is eqivelant to?

tashpop 02.24.2008 05:57 PM

the 22/45/2 is equal to badass. at least it seems so far in my build.

BL_RV0 02.24.2008 05:58 PM

already figured that out. :lol: but what high-end motor has around its performance?

Your joking... But I had my Savage clocked on GPS last summer at 52mph and it was very difficult to manage. I could see the crash at that speed being very spectacular.:oh:
