Hey John, I'll take some advice.

60 foot straight, 17.5 pulse motor, Ko SC 1.5, rubber tire, whats a good starting FDR? Timing on SC and timing on motor?

Any input appreciated.

Thanks

Thanks.

Quickness and not speed is going to be key on a short track like that.
I would have the speedo set on the second most aggressive profile #7 .
The motor with the timing on 10 degrees to start. I recommend the highest "C" rating battery you can fit in the car. Capacity is not that important as long as you never over discharge it. Start with about a 4.4 final , if everything is going well your motor should be coming off the track at less than 140 degrees. I also like to put the throttle exponential on +50 to help me keep some momentum in the corners with out using too much trigger.

Good luck!

Try the same as I had for the previous post ...

The Tekin has way too many options. lol
But the boost may not be effective for stock 17.5 because you will always be in the boost. I'd try it with out boost but an aggressive profile as well as the expo.

Theres a Bullet edition?
Isn't that the SXX speedo? (MOD)
I was under the impression the SPX was "THE" speedo for 17.5 and 13.5
The Losi Excellerin and the Tekin RS and pro models are the closest things to the SPX . The LRP is far and away the easiest to program/use.

Change that 28c pack for a Thunder Power 3200 40c !
You will thank me later. Or maybe just wait till the 4000 40c is available.

The KO Sc 1.5 only goes to 6 so I'll roll one back from there, but when you temp your motor, where do you shoot from? Off the label, or the end bell or a couple of places?

Thanks

John... at least provide CORRECT advice. the Ko Propo BMC Vers 1.5 doesn't have profiles. it has timing settings and a customized throttle frequency profile.

Johnny.. here's background info for you. at the Reedy Race, myself and some other BMC 1.5 users had our duo's on the middle timing hole with timing set at 6 with a customize throttle profile.

i had my automatic brake set at 25 with brake frequent set at 0.794 or 0.792 (i forgot the exact number).

FDR for my car was at 3.9 and 4.1 ( i played with both) settled on 4.1. with the straight being over 140ft. rest of the info you can get from the BMC thread.

also, there's are plenty of great profiles on the BMC thread. check it out. back to 416 programming.
