roller an already with the gearbox changed to adapt brushless motor!

a small ideia as i want to mount electronics on the chassis!

i will use a 3s lipo setup with a 3270kv 4pole leopard motor with a ezrun sc8 esc.
4 pole for more power and less heat and only 3s because the weight of this car that is less of 3 kilos roller and will be less of 4 kilos ready to run.

greetings

Looks like an interesting project and should be fun to drive. One thing that bothers me about the MFR is the drive shafts (not so much the center ones). I have seen a few people come back to the shop with buckled shafts and that was in nitro form. Brushless might be a lot harder on them. Rest of the truck seems decent.

Anyway keep the pics coming. We all love conversion threads here.

I am looking forward to see this completed, I've always wondered about the MFR.

cool looking truck
the ends and shocks look LST ish almost
sc8 esc will be good in there i had one in a 5 kg savage no problem

thank´s to all answers!
i had many electric cars since 2006 but i feel this is my true first conversion and after run 3 full packs today on the car i am really loving this project.
the mfr is freaking fast and have tons of torque!
jumps very well and balanced and steering is great too!!

i am using t-maxx wheels for bashing on dirt because they have good traction!

it stands high and with good ground clearance.

weight loaded even with more heavy monster wheels is 8.10 pounds that is 3.6 kilos.

the ezrun esc works very well on this motor even on 3s and on the end of 20 minutes of each pack motor measure 55 degrees celsius and esc and lipo more cold that motor.
i am really happy with this conversion and this mfr really is a great fun and agile truck to drive.

about dogbones or drive shafts i have already notice that they are the weak part on thsi truck but i will buy optional universals all around if they tend to break or bend!
motor mount is a home made l plate and for now is working without any issue.
more too come because projects are works always in progress!!:yes:

greetings

NICE! Thats a great car now, and I don't think many people have a brushless MFR!

new updates!

since i was notice some wear on transmission dog bones e think on continue the project and mount a center diff too.
i notice that it could be easy since chassis plate is flat and i get my hands to work.
i have already in stock for many time a center diff brushless motor mount from a rc8 so i get the rest of the parts to mount it.
next i made a custom plate to attach to center diff and to chassis staying between both and that´s it!!

the easiet part was made center dog bones with correct leght and for that i use two spare ones from front and cut them and glue them with a special epoxy glue.
this dog bones are not round and top pins come out after heat so it was easy to customize them!!

i bought a new lipo box too from a hyper 10sc truck and fit just perfect and change all stock screws to hex head ones!
also get optional 17 mm's hex hubs and change motor to a 4065 2700kv 4 pole from stock ezrun sc8 combo!

new body is on project too and all i can say is that tha handling of the truck is now a dream.
is corners like a 1/8 truggy with 4 wheels planted on the ground but at same time i can bash it anywhere like a monster!!
weight come to 3,45 kilos with this changes and with truggy 1/8 wheels so yeah it is dawn light and super fast on 3s lipo!

more to come soon!

Nice conversion! CD and all, I also like your choice of electronics:yipi:

Thomas G

thank´s!!
i choose hobbywing sc8 because this is really a great combo for the price and buy this or mamba or tekin here in portugal guarantee is the same!! none!!!:lol:

soo more cheaper the combo more money in pocket!!


greetings

Well done. I wasn't all that happy with your first motor mount as it looked very thin but the new setup looks excellent. Even a center diff too. Wow! Weight is excellent too. I hope it serves you well and keep us updated on the durability of the truck.

so far car is running great either bashing or racing on track and dogbones are handling great.
only blow a rear shock on a local race but since they are plastic it´s normal.
this is a cheap conversion if you get a cheap mfr to buy and it is a blast to drive even on 3s lipo. imagine with a 4s setup....
my friends with e-revos and savy´s fluxs usually break on a dirt bike track were we usually bash and my mfr as ending days without a issue!!
so my concern with weight is giving results!!

greetings to all

new updates to the project.
since i really didn´t like having center dogbones over the chassis plate i get a e-maxx transmission for the car instead the previous center diff.

with e-maxx tranny i got the chance of changing center dogbones for passing under the chassis and the change results on a whole new truck...

http://img812.imageshack.us/img812/3349/imag0015af.jpg
with this tranny i have a superb brushless motor mount and i can run it with or without center diff depending where i want to run!!
i have to dremmel a bit the chassis and made 4 holes for the tranny and that´s it!!
and with center dogbones passing under the chassis i got a huge space over the chassis for putting electronics different!

now i only have to make a custom tranny skid or protection and it is ready for more many hours of fun!!

http://img263.imageshack.us/img263/6021/imag0007acn.jpg
i have not weight the car again after this change but it seems very light again and it runs neutral and with awesome handling!!

another thing i notice is when i desacelarate the car still rolls or still run alot better than earlier with center diff, that means that have less transmission stress between gears or anything similar to that. it feels much more trigger sensitive too!
hope you guy´s enjoy because after 15 cars i had this one is by far my favorite and as been surprised me alot!!

What is the specs on that golden leopard motor? What voltage do you run with it?

Fun to see an old school conversion and a project go through numerous iterations. :)

Takes me back. Enjoy!

is that one: http://www.rcecho.com/LEOPARD-RC-Mod...tor-IM042.html

i run it at single 3s lipo with great sucess so far.
doesn´t heat alot and is a 2 poles motor.
