[karsonas]

Hi from the start and I'm sorry for bad English ... I have LRP S10 blast tx, and I was looking for his motor, and I'd go with electric standard class, but in this class is some limitations: Standard "category: only unmanned brushed 540-560 size motors. That means that I can only use these motor's like this http://www.modelis.eu/rc-models-elek...ai/9-model.jpg
So what engine would you recommend for me?. Transmission can be changed as long as needed.
