I Learned Something Today

Well I learned something today. I was sitting at the track and I was wondering why my buggy seemed slower than everyone else's. As I was thinking that low and behold Nick the Quick comes walking in. I asked him how its going and he showed me his brand new drivers license. He was so proud of it that he had to take his first drive to MC D's and then to the track. So after making fun of his goofy picture we started talking about RC cars and stuff. I started to tell him about my problems and he said lets take a look. Mind you Nick is 18 and is a lot faster than me so I listen to his suggestions. We went out to the track and he drove 1 lap and said my gear ratio is not right I was topping out at the complete end of the straight away instead of earlier. I said how can that be I am running the same gear ratio as everyone else. I told him I was running 78 tooth spur and a 33 tooth pinon. He proceeded to laugh and said that is for a Novak motor not an Orion. As I sat there looking like a monkey scratching my head with an open mouth. He proceeded to tell me that each motor is different you do not gear them the same. He told me that when we were running 27 turn brushed motors the gearing between different brands was like 1 tooth. But with brushless motors it could be a lot different. So we started playing with it and sure enough I had to drop 5 teeth and go with a 78/28 ratio. When we put the buggy out on the track it was like night and day I was really surprised. So now I have to work on the truck. I think I have that close I am running a 78/27 so I think I am close might have to go down a tooth or so. Well that is it for now time for me to get some sleep big snow storm coming and I will have to go snow blow my house out.

Do you worry about FDR at all or is it just the Spur/Pinion numbers? I have no Idea what final drive you are running for your truck and buggy.

yes you do have to worry about FDR but it has come to peoples attention that if I have a FDR of 7.0 with a novak motor and i put in a orion motor the truck will be slower than when the novak motor was in. so I have been told to watch when the motor tops out and go from there.
