First race with the GS Racing R21pbx2 nitro engine. I left the engine pretty conservative on the tune for its first race. With that cosidered, the engine ran flawless today! The first 5 mins was corrupted on the video. Video starts at about 5 minutes into the race. Towards the end of the race, My throttle finger goes numb making it hard to hold onto! lol Hope you enjoy the video! Thanks for watching!
