What is right for me? Lipoly or IB3800? ~Which Motor? 7xl/8xl/9xl? EVO pics inside :) - RC-Monster Forums

R00ST · 10:14 PM

I have sold all of my rc vehicles except my brushless revo project (well still have a novak ss5800 powered stampede might keep as I cant get much for it used)

I will be running a 9920 with either a 7xl/8xl/9xl and not sure on the cell count as of now (I know if I run nimh ib3800 it will probably be 7 cell packs, so 14 cells total)

I have posted before asking about which motor to run, and I was given good info, but I still cannot decide on which motor to get! I want torque, and I want run time. I have heard good things about all 3 of the xl motors im looking into (7xl/8xl/9xl) I am sort-of leaning toward the 7xl just because it has its peak power/efficency with less cells right? therefore if im only running 14 nimh then I wont be taxing it too badly.

I suspect my e-revo to weigh in around 9.5 pounds completed (batt setup obviously will change that number either way) and I will mostly be running larger offroad tires (favorites are the proline 40 series mashers) running mostly offroad but also on the track occasionally. If I go the ib3800 route, I will probably be getting 4 7 cell packs, so I will only be able to switch batteries out once while bashing (biggest reason runtime is VERY crucial!)

on maxamps I can get my 4 7 cell packs built to my specs with deans for about 175 shipped. I have heard awesome things about the ib3800s capacity (running up to 4500 MAH!)

how many lipos can I get (keep in mind I will need a new charger...but would be able to sell my two duratrax intellipeak digital chargers) that would be basically the equivalent voltage/runtime? (so 16.8 volts approx, with approx 4500mah?) how many could I get, and what chargers are available for decent prices?

Here is a pic of the project thus far - should have more in the revo forum soon hopefully. Still need the 9920/ and whichever motor I choose, and already have a 94138 airtronics servo on the way. Since I cant seem to find kyosho twin force battery cups ANYWHERE I think I will just make some out of aluminum angle.

Sorry my camera sucks so bad... I decided to run a cvd to the rear only, because that way I can still get the tranny out without having to unbolt the front/rear ends. I also modded a 3racing revo tranny cover to fit over the E-tranny. I made 4 new recesses so the 4 center screws go straight down to the chassis to hold the tranny in, the other 4 (outer 4) hold the cover down (but also screw into the tranny to futher secure it).

Thanks in advance for any comments/info!

** P.S. ** If anyone knows where to locate some Twin Force battery cups LET ME KNOW!!!

SELL ME UR E-maxx trannY!!!! Welcome to teh forums. Did u use CENTER DRIVE SHAFTS or teh ARM DRIVESHAFTS?

R00ST · 10:53 PM

for about 75 bucks...sure I will! I bought my tranny from a guy ive known online for quite some time (has UE idlers in it). The cheapest I could find one on ebay about a month back was about 55-60 bucks for a stocker.

Just a note, if you cant find a good one on the forums (be it new or used) a good bet is to build one NEW! I built one for my friend (other guy doing an evo conversion) and it only came out to be just over 50 bucks for all new parts. I did have my own bearings laying around though.

*edit*

I have been on the forum longer than you have, maybe I should welcome you! ;) heh, I have been on here awhile, just do more reading than I do posting.

I used maxx long driveshafts that I cut down (hopefully they will hold... didnt feel like doing more dremel work to make a revo shaft work)

Building is cheaper? Well, i saw cheaper bearing sets online. hMMmmmm, thanks for the idea. Where id you buy teh stuff?

One of them flm tranny cases would look real sweet on that truck. The truck looks good now.

if only money grew on trees! (if you find a money tree let me know :) )

can u list the parts or put links of the items off towerhobbies?

R00ST · 11.10.2005, 10:51 PM

You have a PM.

squeeforever · 11.10.2005, 10:55 PM

i would say a 8xl if you cant deside. also, depending on your budget and what your willing to spend i would probably go lipo.

R00ST · 11.10.2005, 10:57 PM

I listed what the cost of the ib 3800's are (about 175 shipped) and I can charge them on my two intellipeak digital chargers. If i go lipo I would have to sell those, so would have approx 250 to spend. Out of that 250 I would have to get enough batts to have approx 4500 mah, about the same voltage as the 14 cells, and a charger (dont know if it can be done or not).

If i find a money tree. I not telling. Just do more shopping. :D
