3.5T LRP Vector X12 modified motor..
Hi,
i received my first modified brushless motor... with lrp sxx tc spec esc.. can you guys help me of how should i maintain the motor and what items do i need to make the motor fresh? grease? and whatelse? oil on the o rings? also one more thing.. what should the final ratio is perfect? cos atm i am using fdr of 6.4.. the internal ratio is 2.5.. so would u guys help me which spur and pinion should be perfect for 3.5T modified motor? thank you |
fdr is way too low...
I use around 8.2 with a 5.5t so i would imagine you would want around 9.0fdr... A light bearing oil on the bearings is all it needs with the occasional strip down to remove any built up dirt/rocks. Check the bearings also (when disassembled) and replace if they are noisy or notchy... 3.5 is pretty powerful. If your not sure what your doing you could end up with a dead motor and/or speedy pretty fast... |
hmmmm,
the speedo and the motor is hot with 6.4.. arrghh man.. the higher ratio means more top speed? just only light oil? like any oil types? |
You're going to burn things up with a FDR of 6.4 and a 3.5 motor.
Here's a suggested gearing guide from Novak for their Ballistic motors which may be a good starting point for you: http://www.teamnovak.com/tech_info/b...r_gearing.html I'm not familiar with LRP ESCs so don't know if the one you have has any profiles with timing but make sure you're in a profile with no extra timing from the ESC. Invest in a temp gun, Pro Exotics PE2 or the one from HPI aren't bad and temp the motor frequently (every minute or so) when you're playing with gearing on that powerful a motor to make sure you're within the temp range recommended by the motor manufacturer. 3.5 is really a lot of power. When I stepped up to one of those from a 6.5 the difference was huge. I prefer a 6.5. The 3.5 is really a handful to manage and everything is under a lot more strain with that much power. |
The booklet that is INCLUDED with the X12 motors states that 4.0 or higher are recommended for High Speed tracks and TC's with 7.2 - 7.4v
The 3.5 with a ratio of 11.0+ is for a 6v application. Of course these are just "guidelines" |
yeah, i use 7.4v 2s lipo.. dont see any 6v lipo... the min is 3.7?????
|
i have geared it at 9.72 for fdr.. is it under geared or overgeared?
the manual for the 3.5t and esc.. it says around 8 something.. i m confused.. i m using the kyosho tf-5 with these brushless stuff.. the esc and motor is still hot.. thanks.. |
come on guys... please help.....
|
Are you racing or bashing up and down the street?
|
i am using it for racing and drag..
jeez.... 6v for 3.5t.. how would i find 6v lipo? is the 8.2 fdr is fine? |

http://www.lrp.cc/fileadmin/lrp_anle...e-090518fv.pdf You should go for an FDR above 10.0 or 11.0 (as already mentioned) |
hmmm, yeah according to drag race... low fdr... but.. i also want to use for touring.. when i use the 6.04 fdr for 2 runs.. it was ok..
since i used the 9.72fdr.. motor is hot and esc seem hot too.. i checked the manual and it should be around 8 fdr.. so it seems that i am undergeared or what?? so confusing.. the esc sxx tc spec is all default.. i checked the blinking lights and stuff...... |
What temperature is "hot"?
|
i think around 60 to above.......
