Title: Again, 4S are powerful. Big Rock!! Post by: GYU HOBBY RC on June 04, 2021, 02:23:25 PM Hello!!
I drove it after upgrading from Big Rock 3S to 4S. 4S have different powers. Hobby Wing series Transmission MAX10 SCT 120A Motor 3660SL G2 Brushless motor 3200KV The price-performance ratio is good. There is a slight heat cut phenomenon, but even if the pinion is lowered a little Speed doesn't seem to be a problem. Currently it is a pinion gear 15T. It's a fun little car. ^^ Arrma Big rock crew cab V3 -Part upgrade- ESC : Hobbywing EZRUN MAX10 SCT 120A Motor : Hobbywing EZRUN 3660SL G2 Brushless motor 3200KV Tire : Pro-Line Racing Trencher HP 2.8" All Terrain BELTED Truck Tires Mounted, AP6336 6x30 to 17mm Hex Adapters Battery : DXF 8400mah 120c 4s Gear : 32DP Motor Pinions Gear for 5mm shaft - 15T Shock : GPM Aluminum rear heavy-duty adjustable damper (front 102MM, rear 115MM) Whee Nuts : Aluminum Wheel hubs 17mm Hex Nuts Runtime : About 15 minutes https://youtu.be/vXPvnVvMmaA (https://youtu.be/vXPvnVvMmaA) Title: Re: Again, 4S are powerful.
