g2r motor/controller

[tallyram]

hi, i'm new here. i've been reading all the posts i can about all the motors and controllers. i will be getting a g2r rolling chassis soon and have a few questions. which motor to smoke all the nitro revo, t-maxx, and hellfire guys at local track? $300.00 for motor is limit. someone recommended a lehner xl2000, so i can use lipos. what about controller? the same person recommended a bk 20120. price is more than i'm willing to give up. $300.00 is my limit for controller also. what about the 12020. almost same thing, right? please help. i can't wait to run with the nitro guys. thanks!

a lehner 1940/6 would be a good motor and the differance between the 20120 and the 12020 is that the 20120 is a micro car controller and has more tuning options.
how many cells are you going to be running???
welcome to the forums by the way

Welcome to the forums - You will definately find your answere to your questions here. Many knowledgeable people here. And then me too - LOL

i'm not sure. i want to run a setup thats really fast and would let me beat the nitro guys on a huge track. i know lipo for sure. i don't know about series or parallel wiring for batteries.

Welcome to the RCM forum!

Well, BL, especially in combination with Lipo, will be superior to nitro on the track.
4S (14.4V) would already be enough. Many run 5S, but it is said this is almost too much power.

If you really want to spend 300 on a motor, get a Lehner 1930 or 1940. But you will find plenty cheaper motors that still kill nitros.

A nice and inexpensive (well, let's say not that expensive) setup would be a Wanderer 8XL on 5S Lipo on a BK Warrior 9920. This combo should give you 35 - 40mph with ease.

As for Lipo in parallel: As much as you can afford! More P equals more mAh (capacity) equals longer runtime.

How long are the races on your track?

Look around and see some videos around. It will give you an idea of what runs how.

Welcome to the forums to.

You don't need a 12020 esc for a xl2000. It don't draw enough amps constantly to need it.

Hi tally, welcome to the forum,

Like Coolhand says, a 120A controller is not needed for the XL2000, if you've got 300 to spend on a motor, i would check out the LMT 19 series. or get a wanderer XL and you've got some money left to step up to lipo. It really is surprising what lightweight does. the watt/oz value gets better.

and lesson 1 in brushless is that the power that the setup can deliver can never be higher than the power the batteries can handle.

I run a 2000XL with a 7020. The controller never gets higher 120F even on a fairly warm day. I would agree with everyone else, for around $300 a 1940 would do an excellent job and kill some nitro a$$. :D

i would personally go with the lehner 1940 or possible a 1950 if you are willing to spend the extra, with the 9920. it would certainly be less than your $600 budget. that on 6s lipo would certainly be a very good combination.

that would be an awesome setup

thanks for all the replies guys. what is the diff. between the 1930 type motors and the "normal" lehners? also, how durable is the g2r going to be. sorry for so many questions, but what other upgrades will i need to race this truck with a brushless setup? thanks for all your help!

[squeeforever]

ok, the purple lehner motors dont have segmented magnets and wont be as smooth at slow speeds and are made in china instead of germany like the black ones. the basics get rather hot quickly. i had one and the speed was unreal but runtime wasnt to good and the motor and esc got hot. the 19 series is definately the way to go. if you dont really wanna dish out that much doe the wanderer xl is the next best thing. they run VERY cool and have gobs of torque and can take from 12 up to 18+ cells for most.
i would upgrade the diff cases and cups along with steel idlers and a strobe slipper.

[tallyram]

thanks for the info, squee. whats the diff between the 1930, 40, and 50 motors? also, does monster carry all the items you listed to upgrade? thanks again everyone.


p.s.- i'm not sure how long the races last, i'll find out in a day or so. the track holds motocross races as well as rc races, its huge.

the diff between the 30's 40's and 50's is the length of the motor basically the longer the motor the more torque it can produce

[squeeforever]

im pretty the 30, 40, and 50 means the length of the rotor (not can) is 30mm, 40mm, 50mm. the longer, the more torque which means less heat, higher gearing with less rpms which equals to more power.
