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.
