Help with LST2 brushless motor choices - RC-Monster Forums

I ordered the Castle 1520/1Y from RC-Monster. I like the 200$ price tag for a finned motor. I have a Castle 1515/1Y in my Eight-T and love it. Hopefully I'll be ripping up the desert here in Iraq next couple of weeks.

It fits, but the 6mm shaft will cause pinion issues. Good try Harold, better luck next time. Good thing you are not the "oracle" of brushless, newbs everywhere would be screwed...

Ding, time for a cookie!

I will say the 1521 1y does great on 6s. So the 1520 cc motor should be fine. I ran a cc 2200 on 5s with truggy size tires and it did very well too. But if you plan to run bigger/heavier tires go with the 1520. 1600kv on 6s seems to be the ticket as it falls nicely with the 63/25 gearing that fits the tdr mount, and available setscrew pinions.

What gearing are you going to run with that 1717? It's hard to get good gearing because it is too fat. That's what I meant. Duhhh

The first batch of 1717 was releast with a 6mm shaft but has since been changed to 5mm. Give me some time and I will let you know if the 1717 works. I have been a little off with my project because I purchased FlexTek arms and New Era parts but in a few weeks I will be ordering the motor and ESC. I am not in a hurry because we have snow all over the place in Pa.

Well you can get 25/63 without any issues. And if you trim the trans mount by the motor a little you can get it almost as close as a 15 series motor. Big pinions are a requirement for the lst, we just need some 26-30t hardened pinions...

The way you said it you implied that the motor would not physically fit on the tdr mount...

Eat your food Tina!!!
