Has anyone there tried modern standard micro gear? The weight savings and performance of brushless motors and lipo's should thrill the crowds. Why are they bound to such heavy outdated gear? Do they have rules on what type of rc/motor combo they can use?

micro receiver/servo + lipo + brushless will work great! but too much cost for poor boy in Thailand :-)

Speed for now is 60-80Km/H for 2AA ni-cd battery ... do you think ? worth to upgrade to modern gear? or risk of sink into deep water (if crash) :-)

Drag not over 3 minutes , free style 5 minutes.
Lipo will longer but the small brush motor dosn't have water cooler .. will die easily

For long run go with 2cells lipo + brushless motor with water cooler both ESC and motor

With 2AA batts and brushed motor, wonder what kv of the motor is. Maybe that gear box gears up rather then down and thats how they are getting the rpm up.

Yea agreed, I took a closer look at the gear box its geared down. So its all on the prop pitch and the torque of the gear box addition.
