Just because one sticker is slightly more advanced than another, does not mean that motor will be faster. It simply means that motor's actual ZERO mark is slightly shifted, and since the sticker is keyed to the zero mark, and the sensor board position is measured by the sticker, all the Ballistics are timed identically. (<--- good idea on Novak's behalf)

Yes it was a good idea for Novak to do it that way. But people can also advance the Ballistic timing past the built in stop and get 5-10 more degrees of timing. Then the just move the sticker to show 45*or 0* of timing. If I remember right the end of the label is about 50* from the factory set location.

Ok, Now I see what Greg was saying. I was not visualizing the motor while I was talking about it.

21.5 kv rating 1800 25.5 kv rating 1550
tire dia PI fdr kv volts avg " per minute " hour " per ' ' per mile MPH
2.6 x 3.141592 / 4.8 / 1800 x 8 = 24504.4176 x 60 / 12 / 5280 = 23.20494
2.6 x 3.141592 / 4.0 / 1500 x 8 = 24504.4176 x 60 / 12 / 5280 = 23.20494
so if you make the 21.5 4.9 fdr then they should be slower for the class and give the new tech the advantage. people need to have the understanding that this allows them to run without having to buy new equipment and still allows those that play by the new rules to have the slight advantage.

so that being said. I may have to adjust the number and track layout would make a difference everytime. but just overall base numbers is sometimes enough to keep everybody happy. it's club racing for bench racing bragging rights. now national level you got to hold the line on the rules.

I'm hoping that this is not a problem at my track. I'm making it a FDR rule for both motors with the understanding that the 21.5 would be slightly slower then the 25.5

I really like this idea for our situation. We were talking about having a deadline for everyone to comply with the new rules but that forces people who would like to run 25.5 to wait till the deadline. This encourages folks to make the transition.

well even the difference between ballistic and ss motors are different figuring you can go to 45 degrees on the ballistic and only 42 without milling the plastic (that I wouldn't know anything about) on the ss motors
so that being said. I may have to adjust the number and track layout would make a difference everytime. but just overall base numbers is sometimes enough to keep everybody happy. it's club racing for bench racing bragging rights. now national level you got to hold the line on the rules.

So, if I understand this, you are limiting the 25.5 to 4.0 fdr. How far off the pace is that from what someone would be running with no fdr limit?

Been running a 25.5 motor in my VTA this summer against 21.5 VTA cars. I've been running a 4.1 FDR and I'm more than able to hold my own in the infield. However, the 21.5 definately has me beat on the straight. I was really surprised that the 25.5 really didn't feel slower other than the straight.

All of our BL escs are designed for optimum performance with the 30 degree factory timing in our motors. All of the BL motors that we have (ever) made have been set at this 30 degree timing mark; we do not recommend changing it. Once changed, there is no way for a user to re-set it to 30 degrees---it would have to be returned to us. Replacing a rotor or wound stator also changes the factory timing slightly.

The Nashville crowd (Thunder RC and Cool Springs) has always had an interesting perspective on VTA. They have worked very hard to promote it. When they first started, they were very relaxed in their rules. Then when the attendance numbers built up, they split the class into a pure VTA and a Relaxed rules version. This way they always had something for the kids and the noobs and those who just wanted to try it, and they had a class for the VTA guy who shows up from out of town and runs Official rules. What impresses me most about that group is how they have always been able to promote and support the Official Set up without necessarily ramming it down. Perhaps I am biased about the Nashville crowd because I get along very well with them. Perhaps I get along well because of their perspective.
RobK has a difficult postition in that his main goal is a uniform set of rules nationally. He therefore cannot afford to make exceptions or be soft on the rules.
Cheers to all who think this is a great class. And here's to all who love it and do their best to preserve it and cultivate it.
