I'm wondering if a brushless Rancho conversion is possible but not sure about gearing and space I could get more space with these anyone have any ideas.

Update found this http://www.amainhobbies.com/product_...ducts_id/24952 witch is similar to Rancho layout I wouls have to get rid of throttle and brake servo can brushless motors stop like have braking ability look at lay out.

ehroof

that should work but i am not 100% sure.

guy4x4

Im not sure either just need a motor mount and I can get it to work I think

guy4x4

Ive ordered a motor now need to find a esc here is the motor the 8xl http://www.offshoreelectrics.com/pro...prod=fei-540XL

ehroof

Nice, you will have to keep us up to date on the progress and post some video.

guy4x4

Will do also what size esc do think 120a.

ehroof

lol, 120amp is a little over kill but why not

my brushless Truck flips forward when i hit the breaks with 3S lipo...
you'll be amazed with brushless power...
p.s. : watch the heat...

muratt2007

another thing came to my mind: you can use bigger pinion.
4S lipo should be fine... 2000KV X 16.8V = 35.000 RPM

guy4x4

What pinion would be good 13t or 14t.

guy4x4

I think I can run a 5s lipo ordered speed controller to here is pic.

muratt2007

5S is not advised because of the extreme RPM you'll get. You can destroy the motor because of the unnecessary RPM. But people use it and they say its too fast, no need to be soo fast... also as i know 8xl has 40.000 RPM max revolution limit. so 35.000 seems to be the safe revo speed.
with 35.000 rpm you'll see that your rig is wild...
theres not much difference between 13 and 14 teeth pinions(for me) so you should go with the bigger pinion(14t).
also you may order and try a 16T pinion for testing heat and speed.
also can you can put a heat sink and fan so you can drop the heat(do it after starting to use the motor.)
you can put on a water jacket to the motor.( i dont know where you can find the pump)

another note: my truck is 41.000 RPM Brushless and i can never put on full throttle, so dont worry about more RPM... 35.000 will be too much also...

Thanks for all the great info muratt2007 also thats a cool video If i get 4s lipo whats a good size 5000 battery thanks.

muratt2007

8xl dont ask for much amp so you can use any fine lipo over 4500mah with 20-25C discharge rating. i use 4500Mah 20C Broadamp and they go good.
depending on your budget you shall get the highest C rating you can=25C and highest amp battery you can afford.

More technical info:

4500mah X 20C = 90 Amper/hour
4500mah X 25C = 112,5 Amp/hour
5000mah X 20C = 100 Ah
5000mah X 25C = 125 Ah

8XL will use around 20-25 Ah avarage and you'll get about 20 minutes of runtime. if you use small pinion your runtime will be more, if you use big pinion your runtime will decrease but speed will be much more.
also at acceleration your motor will draw high amp like 70-80 ampers.
The higher C rating and higher mah value and the better battery quality will mean longer runtime, longer lifespan of battery.

I was thinking how does the brushless setup stop the truck how do I brake do I set up esc to do it.

muratt2007

you can see how strong the brakes are from these two videos:
http://www.vimeo.com/1371596
http://www.vimeo.com/1631537 (the first and last scenes)

these are with 3S your motor has much more strenght from mine so you can expect more braking power...


And you can adjust the brake power from the esc.
when you push the trigger forward for the first time you make brake when you leave it and push it for the second time you go backwards ( basics :-)

Good info muratt2007 here is as far as I got waiting for parts.

guy4x4

Just a update recieved my esc and motor have a look now need a battery the expensive part[&o].

ehroof

looking nice bro, when is the video going to be out?

guy4x4

Saving for battery so maybe in a few weeks cross my fingers LOL.

guy4x4

Ok did'nt like my motor mount so found this won that is a perfect fit also got my lipos so just need to do some configuring on were to place everthing but I have a good idea just ordered some velcro straps when I get them will shoot a vid here are some pics.

ehroof

that looks great bro, let me know how you make out. I love the 1/8 brusless buggy i have, crazy torque.

kuppler

Wow... Looks Killer. cant wait to see some video of that bad boy running....

Redharris

That Looks Awesome!
I've thought for a Long Time that a Full Scale 1/8 Brushless Truck would Sell.

I was THINKING that the Novak 1/8 Conversion Kit would work for my Truggy.....

I saw the Novak Motor/ESC at my LHS for $220, and those Novak Conversion Kits (Hardware) are about $80.

Im Thinking Your Route is Best....
You are probably saving some Cash by doing it yourself.
It seems to me that the motor MOUNTING Plate is the most crucial part.......Let us Know what works out for you, so WE can give it a Try!

tbs

Your car is looking great.

Hopefully I can get mine going today with the new ESC I got yesterday..

Will keep watching your thread to.


And thanks for the pictures you posted.. [8D]
