Being that Iím using a Tekin RX8 gen3 whatís the minimum and max motor I could use?

Although I have trenchers xís I might go shockwaves instead since I do hit the pavement a lot.

Or another set of terrain crushers.

Also should I scratch the rx8 fan and go after a r1 fan like you did??

And one more million questions should I stay light on the diff weight or do a 50/200/30
Or aggressive like I did my lst 200/500/100

Sorry for all the questions
The MT shock towers are shorter so they'll give you a little more ground clearance. I don't own a Tekin but it can probably fit a 80-85mm length motor. The larger fan certainly helps, just depends on what your doing. The front/rear diffs aren't really picky about the weight, unlike the center, I like 100k.

Oh I thought the et48.3 had room for 95mm and 105mm motors

That explains the shock tower recommendation and if we are talking 5mm I’m not worried
10mm now that might be worth $60 for the shock towers

The chassis layout is the same on the MT/ET, it's just longer at the rear on the ET. You have to relocate the ESC for long motors. I'm not sure what the exact height difference is between the shock towers.

I just added the 1440kv 4070 tp my savage, running 16/48 and 6.65 inch tires and I am not so impressed with the temps, I thought it would run cooler but now it is more or less as hot as my leopard 4092 1730kv with no heatsink. No IR temp, only checked with fingers, and the temps outside was cool.

Am I geared too low? I mean this is a 8s motor to beginn with. It is geared for around 69 mph, do I really have to run heatsink and fans on this as well? I thought I wouldn't. I know the 1730kv leppy run hot on 6s with no heatsink and fan but I didn't expect this from a 8s motor that is lower KV and also longer.

What was your gearing with 1730kv motor? Was it same as you have now or did you re gear it

Funnie, do you have smaller diameter tires you could try? If with the smaller diam. tires, your motor temp gets hotter, you'll know your average motor RPM is too high throughout your run, causing the heat. Also, do you have a center diff installed or are you using the stock transmission?

I use center diff with 500k fluid. I base my gearing on what others run, but I am not surprised if I have been geared too low all the time. But at the end of the day these are boat motors so they are watercooled and the can is smooth, no fins, so the heat won't dissepate as effectively as cans with fins.

You can’t base your gearing on what others run only use theirs as a starting point.

We all drive differently.

My lst with center diff started with 1800kv 48/16
Then 48/14 50/14 52/14 second motor 1500kv 52/14
Now I’m using 4092 1480kv 54/15 and in an all out grass run my temps are finally in the 130’s and occasional 145* spike but single fan has kept it in check.

If I can keep truck straight speeds are 50mph

If I want more then the trencher X’s gotta go for a more consistent tire.

My opinion you should try a 48/14

I am glad you posted your findings btw this motor was on my list for my et48.3

But now I might stick with a Tekin 1350kv or 1500kv motor

If your fingers didnít sizzle, thereĎs still plenty of room to gear up; and actual temperature readings might improve the quality of the advice you will get.
