Tekno RC BLOK 21aP .21 Oil Bath Broken-In Off-Road Nitro Truggy Engine
crazy amount of power and unbelievable torque. This motor one crazy piece of machinery. I put this in my NT48.3 and it has plenty of power to get it through some of the toughest jumps I have encountered. Great motor and a great price. It is pre broken in with Tekno EBIS, however I would suggest to idle one tank and use another tank under load to start getting it ready for a tune. On the third tank I would start to race tune and by the 4th tank you should be able to get your race tune fully integrated.
