Brushless Kyosho S-RR

[Patrick]

The 2 ST-RR's at my track haven't had problems yet on 4s trakpower packs. One has a 1515 2D (2050kv) and the other is lehner 1940 7t. They both have a fair bit of power for the track, but they haven't been doing on road speed runs with 6s or anything like that.

It was really hot today in Socal, perfect weather to see how the E-STRR would hold up on the track. Without any adjustments to the suspension or brakes (from it's former Nitro settings) I ran one 4s lipo thru the truggy to get a feel for it and to see how hot things would get. Ambient air temp's high 90's. After 10 mins, ESC = 170 (a little hot), Motor = 132 (Great), Batt = 108 (not bad). Not bad considering how hot the ambient temps were. The brakes were way off, way too much front bias (almost flipped over everytime I braked). Suspension was a little too soft as well. I lucked out and a JBRL racer that I knew showed up and was impressed with what he saw and wanted to take a spin. After another 4s pack, he was stroked, he could not believe the power/torque a brushless motor could produce. He made some adjustments to the brakes and put in a few more laps. A pretty good first time out.
