Do LRP x12 Octa Wind 6.5 motors just run hot? I can't touch mine after a five minute race and I have the gear ratio spot on (19/76 losi 22) with the throttle profile on 1 and boost/timing off (SXX TC ver 2) , I have got the full timing advance end part in.

Anyone :confused:

Running lots of timing advance does make motor run hot but the x12's are known for running very hot but they seem to like it and they can tolerate hotter temperatures than most other motors.

I'd have to disagree i'd run mine oober hot until all the solder run out of it and it stopped dead, it's resoldered and runs fine now but still hot with any gearing but i wondered if it was put together with low melting point solder.

Hi

long long time ago I was beefing cause the same story...my X6sq indoor on the beginning geared to 17/78, LRP SPH Comp ESC timing ZERO everithying switched off... and the 6,5 Octa was stil hot.

Than I installed cooling, lillbit better but still very warm.

Now indoor I run 23/78 and no cooling....the motor is hot but I dont care,, and probably the Octa also:thumbsup:

Outdoor I run 8,5 Octa and same story.... HOT:thumbsup:

Ok, I'm going to try going down one more pinion size and if it still runs hot then hot it will run :cool:

Yeh the alleged gearing is 10.3:1 2wd i had mine 20/78 10.14:1, LRP SXX profile 1 no drag standard timing etc in my 6sq'd when it cooked i now run a 17 pinion but it still gets hot and like you no longer care it'll eventually die and i'll buy something different.

How hot is it ? in degrees...

I haven't tested it but I can't keep my finger on it, my old brushless Tekin motor was nothing like that.

What you doin in this neck of the woods :D you got a useless losi system

depending on track shape...60-80C but one I top 110C of my 6,5 Octa. But do not do that too often...risk of demagnetisation (neodymium), llosing the adhesion between the magnet and shaft....

I say up to 80C the Octas are safe regarding lifetime.

Which is the best temp gun for motors, are the nitro ones the same thing?

we thermal tested a 6.5 octa and 5.5 in the same cars with the same esc after 5 mins indoors the octa was running at 116C and the 5.5 was at 123C according to lrp there good for 200c:woot: i can fry spit on mine ever time I race

The X12 are very, very popular in the 10.5 TC classes these days. They are the only motors that can withstand 100+ *C after a 5 minute run without permanent damage.

As i said the solder run out of my 6.5 and it stopped dead i temped it about 102*c:thumbdown:

Easy to repair with high temp solder. If that was a Ballistic that got to 102*C then that would be game over.

I too am looking at these, 7.5 for 2WD and 6.5 for 4WD except in the Nosram flavour

I'm not liking the ORCA motors at present matched with my SP ESCs

I got my 6.5 Octa Wind at 65-70 degree's after five minutes outside in a Losi 22 (19/76 gearing):thumbsup:

The 100 degree's + all stopped when I took the full timing advance part off the end of the motor, don't need any timing advance with a 6.5 Octa Wind in a Losi 22 :lol:

What's the stock timing on a LRP motor?

I've been running about 18+ timing on my SP ESCS.

And repair it i did and it's been as hot since just thought it'd have better solder as stock! It run's happily away at 80* but that's well under geared to recommended ratio.

I've been running about 18+ timing on my SP ESCS.

Stock timing is -10 degrees, this is also recommended by LRP to be left alone but there is two more end timing parts that come with the X12 motor's that will change it to -5 degrees and 0 degrees, and if you then turn them around it will give you +5 and +10 degrees.

Just to help those who are not sure about this,

The timing insert with 4 dots on it is -10 degrees (standard) - highest torque - lowest rpm - coolest running

I have a losi 22 with a 19/76 and a x12 6.5 and a sxx v2 out side run hapely in the 50 to 65 range but indoor on carpet motor is In the 80 Mark and the sxx up in the 103 Mark very hot but it don't seem to care

I use to Run the orginal X12 6.5 in my Durango and and CatSX a good motor just aways ran hot

never ran any thing other then the -10 (came set at Zero) I think that the early Nosram and LRP escs that i had, used to run with around +24 deg fixed timing so this was a cause for the motors to run too hot the later ESC had a differnt profile which the motors liked better (designed to work with the X12 Range) and would run a little cooler.

one thing to always keep in mind, you must oil the bearing .when these motors run that hot they tend to dry out the bearing and then Seize up
a lot of people think that Brushless motors are Maintenance Free but there not . I admit there a lot less bover then the old Brushed motors but they still need to be spripped and Cleaned every so Often.
