HELP/CONFUSED
Hello , sorry I am new too on road/TC5R , a few posts back someone asked what was the best FDR for a TC5R with a NOVAK 17.5 and the response was 4.2-3.8FDR use a 72t or 75t spur 48p. When I put either of those spurs in there is not enough adjustment room in the motor mount too use the correct pinion(19t/20t) to get that FDR. Am I missing something , not doing something right. Could someone please help I`ve got my first race starting tommorow and I just need too know what spur/pinion is best too start of with for the 17.5 on a medium size track or what I`m doing wrong? Thanks too all this is a great thread keep up the good work all!!

A 100 spur with a 52 pinion puts your FDR right at 3.8

the FDR really depends on ur track because at my track the 17.5 guys role with a 4.6 FDR

72/34 would give you 4.2
64/32 would give you 4
61/32 would give you 3.8

First off thanks for all your help.To be totally honest with you Im not exactly sure how too figure out FDR if you could tell me how you do it that would be much appreciated

To work out FDR you do
Spur / Pinion x internal ratio..
Example...
72 / 34 = 2.11
2.11 x 2 (tc5 internal ratio) = 4.23 FDR

In the order of operations doesn't multiplication precede division? Though I suppose in the case of calculating gear ratio, it doesn't affect the outcome.

P(lease)
E(xcuse)
M(y)
D(ear)
A(unt
S(ally)
is the pnemonic we use to teach the order of operations, generally 6th-8th grade math. P(arenthese or grouping symbols), E(xponents), M(ultiplication and/or D(ivision) left to right, A(ddition) and/or S(ubtraction) again from left to right.
Doesn't matter if calculating gear ratios or whatever. To experiment try your hypothesis out...do the indicated multiplication first and then the division. You will end up with a very different (MUCH smaller, something just a bit over 1.0 in fact) result.
