Talk 1520 - your experiences

How's the 1520 compare to say the Tekins TT2362 (1700kv truggy motor)?

I also like the specs on the 1518 for my mbx6t racer. Might be an option as well.

As my opinion 1520 handle much more power than the tekin truggy. Tekin truggy handle as much power as a classic CC/neu 2200kV or less (1400-1500W).
The 1518 and 1520 are longer, by 3 rules calc method it would have maybe 1800 and 2000W

Interesting....

I guess my only concern is over-powering the truggy. I'm sure for bashing with a maxx or something more substantial it would be great fun. Anyone running one of these in a race setup? How's the power/application?

The benefit to the powerhouse could be increase efficiency and less heat pulling similar gearing.

[nuz69]

That's it, the motor pull out its power only if you ask it, and the efficient is better if you dont push it to its max output. Therefore a 1520 in a MAXX wouldnt be incontrolable, unless you gear it for 80 mph ;)
Too much power is always better than not enough.

Yes, yes, yes... nough said

lol!

I guess that's the question then, what is "enough" power. By the too much power is always better rule, the 1717 would be a better option still, no (other than it's huge)?

I'm just looking to setup my mbx6t for racing. Being the 2200kv neu/CC setup has worked well in racing setups, makes me think 1400watts is enough for a 9.5lb truck.

Just trying to understand here. I've been a nitro guy forever so trying to get my head wrapped around all of this . ;)

Where the 2200kV is well, the 1520 1Y 1600kV is always better , because its would run for example 40-50 °F lower than the 1515 1Y for only additionnal 50gramms. The 1717 has same kV than the 1520, but is bigger and weights 150 more than the 1515 1Y ===> it requires relatively many AMPs and is a little heavy for a 1/10 monster truck.
2200kV works well but go easily hot in a monster truck when you push it in summer and its better to run cold for efficiency and longer runtimes.

[itbvolks]

Ok, so then how does the 1518 compare to the 1520?

Little more kv might be beneficial on 5S. Still seems like a brute of a little motor!

[nuz69]

1520 on 5S with bigger pinion would be better for same speed ;)

[itbvolks]

So a 1520 on 5S running a 17-18T pinion (final gearing 17/46) is feasible?

I am interested. Looks like the motor only weighs about 50-60gr more than my tekin.

[nuz69]

Yes, you could gear up to 55-60 mph without heat issues with this 1520 :)

[itbvolks]

Double.

[itbvolks]

Sounds like the 1520 would be a good fit overall for the truggy. It basically means I'd be down roughly 1850rpm with the reduction in KV but I wouldn't think that would be too tough to overcome with gearing changes and if it'll pull the bigger gear without overheating (which it sounds like it will with ease), that would be ideal....

Certainly seems like the motor makes significant steam!!!

I went out for a run again after tying fishing line around the savage tires so no tire balloon effect for this test. I tried 4* of timing and ran it for 15min. I burned up 5ah at 23v(6s) in 15min with 16/54 in a 12lb. rc8t. 125*F motor temp. Something seamed a lot more tame about it. I think it was the lack of the tire balloon effect. I will have to retest with a higher timing setting.

A 12lb truggy?...That thing needs to go on a diet!
