RCbutcher Posted September 9, 2014 Share Posted September 9, 2014 Be quick and there's a brill combo for 100 in the sales under bens clear out or something. Castle 1800kv Quote Link to comment Share on other sites More sharing options...
KYOSHOKEV Posted September 9, 2014 Share Posted September 9, 2014 Motor wise you want something around 2200kv bud 1800 is a bit low for a truggy 150A esc is fine Hobbywing Xerun is a good set up for a truggy Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted September 9, 2014 Share Posted September 9, 2014 Toro stuff seems hit and miss, for the extra few quid buy the HobbyWing combo, even second hand to save a bit... Provided they aren't thrashed to death it's worth the saving... Move away from 120a systems, just not worth it in a truggy. Quote Link to comment Share on other sites More sharing options...
scotty1986 Posted September 9, 2014 Author Share Posted September 9, 2014 im lost lol ive got a 2300kv 120a system but told that wouldnt be much good as it would run hot kev?? also if i move to 150a systems it will mean buying new batterys i already have 4x 4s but there only25c so kick out 120a Quote Link to comment Share on other sites More sharing options...
scotty1986 Posted September 9, 2014 Author Share Posted September 9, 2014 ive got the 120a system in the hong nor kev would that cope in the 8t as the leaord can isnt as fat as the turnigy one Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted September 9, 2014 Share Posted September 9, 2014 Why are you wanting to swap the current system to something that's the same lol... Also, just buy some better LiPos for a better system, it'll run so much better. Be like night and day Quote Link to comment Share on other sites More sharing options...
scotty1986 Posted September 9, 2014 Author Share Posted September 9, 2014 because the turnigy system will run to warm and i cant seem to set the brakes ,, im just on a budget at the mo (well always on a budget 4 kids, wife,, dog ,, house,, car,, not a high enough paid job and a trip to legoland on friday) lol so just want a system that i can use the batterys i already have in,, im not looking for double backflips off the line or a 100mph 8t just something with the same power as my stock hong nor lx2e buggy and ill be happy i only bash and take the odd trip to the track Quote Link to comment Share on other sites More sharing options...
KYOSHOKEV Posted September 9, 2014 Share Posted September 9, 2014 What gearing is the 8ight running bud ??? Quote Link to comment Share on other sites More sharing options...
KYOSHOKEV Posted September 9, 2014 Share Posted September 9, 2014 I`m fairly new to brushless my self but from what i understand its all to do with size and weight between the truggy and the buggy mate the fact that the truggy also runs different gearing and size of wheels ect. I have a brushless 8ight and a brushless hong nor truggy and they both run 150A hobbywing ESC and 2200 or 2250 motors and the temps are fine and they last a 20 minuet final but only at 85% throttle My 8ight is running 16/45 gearing Another thing you need to look at is your batteries bud you really need around 60c minimum i run 4s 120c nano`s in mine and the batteries are fine.

Are you sure? That's not how I read it. The sum in the leccy section guide says mah/1000 x c rating. I guess it depends on what mah battery you're running but my 5000mah 30c should kick out 150a. Go up to 40c and you should be well clear for a 150a esc. If I have it right? On my 120sc8 & leopard 2650kv setup everything runs mildly warm, motor is the warmest but I can still keep my fingers on it.

cyronn Posted September 9, 2014 Share Posted September 9, 2014 40c Lipos should be fun in a truggy but running a buggy motor 2650kv is not ideal, as the motor does not really provide the torque needed. If you are planning just to run 4S lipos then ideally you want something in the 2000kv to 2200kv range. If running 5/6S lipos you want something in the 1800kv to 1500kv depending on gearing. Rule of thumb is volt up gear down. Quote Link to comment Share on other sites More sharing options...

You got it right but it's always best for the LiPos to provide more than is needed, they seem to run nicer and cooler. I've found anyway, I run 5.0 35-70C on a 150a system and it runs awesome. Also if funds are tight, sell your current combo and LiPos if it's not working out and just save a bit. Cutting corners will only have the same result bud.

scotty1986 Posted September 9, 2014 Author Share Posted September 9, 2014 (edited) not trying to cut corners mate ,, just i have a brushless buggy and have 4x 4s batterys for it so no point in selling the lipos,, could i run something like a 120a hobbywing esc and 1900kv motor so the motors tourqe would make up for the 120a esc?? ive just put the system out the hong nor lx2e buggy in the truggy ,, (hobbywing 120a esc 2100kv leopard motor with punch and timing turned up as it was set in the buggy) and it ran sweet although the motor did get warm ,, wasnt scolding hot to the point i couldnt hold it it was pretty warm to the touch,, buti could hold my fingers on it for as long i wanted ,, would a slightly lower kv run cooler??

I don't think that's really necessary unless using small mah batts? I wouldn't say a minimum of 60C personally, but different people run different things. I think as long as the LiPo can provide more than is necessary, that's enough, anything higher just shortens the run times not by much but over the course of a day it would be noticable.

Jernst20 Posted September 10, 2014 Share Posted September 10, 2014 You want 2000-2200kv ;and it should run pretty coolYou want 2000-2200kv ;and it should run pretty cool Quote Link to comment Share on other sites More sharing options...

scotty1986 Posted September 10, 2014 Author Share Posted September 10, 2014 oho if your not even going to bother trying to answer my questions then please dont comment ,, if i wanted to run a 150a esc i would be asking about a 150a esc,, i just want to know what motor and pinion i could run in my 8t with a 120a esc with a 45t spur ,, without anything getting to hot ,, thanks to those who have answered me with sensible answers relevant to the questions im asking Quote Link to comment Share on other sites More sharing options...
Deafty Posted September 10, 2014 Share Posted September 10, 2014 2200kv on 4s mate leopard 4280 or 4282 are great cool running motors. if u r running only 4 s then 150a esc wont munch ya lipos but 120 will work check the owners thread 4 pinion Quote Link to comment Share on other sites More sharing options...
cyronn Posted September 10, 2014 Share Posted September 10, 2014 (edited) Ideally for any 1/8th scale imo I would have a 150a ESC, whether its for 4S or more. I like to have the option to go 5S or 6S lipos for when I have my mad moments, But a 120A esc is capable to run it on 4S but seems bad practice to me as you are on the limit of that esc. edit: I've had my 8T for near 4 years now and its still the best RC I have owned with a few mods.
