Talk 1520 - your experiences

[snellemin]

I finally used the 1520. Stuck it in the TM buggy on 4s and Qaurk esc. Works pretty good.

[ANGRY-ALIEN]

... wow... do you think you have enough power for your buggy now?

[nuz69]

I use a 1520/1Y on 4S in my buggy since a while now. I have better runtimes than my previous 1515/1Y, but it add 59 gramms

[snellemin]

I agree that it runs cooler then with the Pletty. It accelerates harder then the 1512 1400kv motor that I have. The weight is killer though, but I figured I stuck a V8 in Civic and have to drive different. Gearing is 46/23 and I'm waiting for Mike to get his 26T back in stock.

i use a 6 spider ofna diff in my savage.. i thought it was the only diff that would survive the power!!! i have used 100k, 150k and 300k oil.. but im currently using 500k in the centre diff now...

edit...

alien... your truck is performing nicely on 5s with the 1520... how much does your truck weigh and what gearing are you running with the cetnre diff???

Yep, it's a fatty, but it shore moves well... it weighs approximately 11 1/2 lbs and it's geared 52/17 (mid 40s)

Currently im weighing around 15lbs (elephant of a savage) and i was geared 12/47 and only run 6s... but i think i am going to up my pinion to a 14 or so as my temps are pretty cool at the moment...

Thanks for the info... You have some big gearing, but your truck is 3-4lbs lighter....

[ANGRY-ALIEN]

hmmm... from the temps and the performance of the motor so far, it appears to be slightly under geared actually... i ran it on 51/18 for a while and it was insane...
wasn't easy keeping the front on the ground off the line... when i did get them down, the truck was really quick...

On 6s running roughly 13/48 and badlands, i was supposedly geared for 50-53mph or so... but i was clocked at 43mph (speed gun)...

I am definitely going to gear to around 58-60mph which should give me an actual top speed of around 50mph or so... I wil ljust monitor my temps closely....

[ANGRY-ALIEN]

Interesting... Ive been thinking about asking the local police to give me some help with their radar guns, but i haven't gotten around to it yet... it definitely would be cool to see the actual speed of my truck...

Alien

[Jahay]

what i personally have noticed is that your actual speed is usually 8-10mph less that your hypothetical top speed... Seems to be the same senses for buggys and truggys etc that we have compared to at our meets.

[ANGRY-ALIEN]

8-10mph??? ... that's quite a bit considering the scale of the car... hmmm... I'll do the radar test with a couple pinons and make some comparisons with the calculator...

The 1520 Is a very nice motor. I am installing an 8ight CD with Nova-RC Cup. Panda what kind of Diff did you use with the Nova Cup? I thought these would be near bullet-proof...

It was all associated gear. The nova cup doesn't have a mark on it. It was just the pressure trying to separate the spur and cup, it loosened the screws and affected the shimming. I need to really crank on the screws. That's why I cut slots in the screws, I am too afraid of stipping the hex.

I like that mod... I have stripped so many when trying to remove them for maintenance..
