yup... my GPS was annihilated after only one speed run with my first MMM 2200 KV combo.
I had a Garmin GPS Etrex. Got it for $69 4-5 years ago. Today it's around $99-$129. I figured the price would drop, but apparently the value of it went up.
So what are you guys using? GPS or Speed gun? What kind, what brand, how much?
My company recently paid me a $50 bonus check.
I want to get a speed gun, but I question how accurate they really are. I see an advantage using a speed gun... Unlike a GPS, no added weight on the truck, and less wind resistance.
Could I mount a speed gun on a tripod and drive right by it, or do I have to aim the gun at the Revo as it passes by?
