I get three full runs from my 180mah rx pack and a Tekin. My car is also faster than the BD equipped cars at our track. The only time a Tekin is slower than an LRP or BD is when the tekin is not properly set-up. I've run all the current speedos but the GM. I always end up back at the Tekin. Smaller, lighter, faster. Of course LRP has recently made their esc's user updatable, and that new Nosram would look great in my CRC cars........
