Default LRP Vector X11 13.5

Hey, guys.

So I've had 3-4 mamba maxes over the past year or so and I like them, however I'm interested in experimenting with the LRP systems. I don't know much about them, so whatever info could be helpful.

I understand they're sensored and all of that, but I'm not sure what the turn ratings are equivalent to. My guess is the 6.5 is "similar" to a brushed 13t? and the 5.5 would be similar to a 11t? and the 13.5t would be similar to a 27t stocker?

Anyway, if you guys could help me out on this I'd appreciate it. I've got an FT TC4, FT T4 and an Academy SBV2 that I would be running with this system. Thanks!

-Jeff

I love the LRP system. easy to program, good setting range and not too big or bulky.

I think:

5.5 = 9 turn
6.5 = 11 turn
7.5 = 12 turn
13.5 = 27 turn (or more like a 25 turn)

I typically use a 7.5 in my 2wd and a 6.5 in my 4wd on a loose track. If traction is good I'll go to a 6.5 in 2wd and 5.5 in 4wd. I don't race trucks.

Cool, cool.

So, is the 13.5 stock legal or still considered a modified motor according to ROAR rules? Thanks.

They are still illegal according to ROAR regs. I've been allowing them in stock at Planet and they seem to be equivalent. The fast guys will still win with either, but the newer guys will probably notice a bit of an advantage. If you don't know all about building and running a brushed motor you will probably be faster with a 13.5. We are probably getting about 50/50 brushed/brushless now.

Yeah, they are not legal for stock racing in ROAR events, but we also allow them in our stock racing. We did several tests and they seem to have a little more low end but a well tuned brushed motor had more top end. I don't think there is much of an edge either way. I just like the lack of maintenance of the brushless.

The 13.5 motors (LRP and Novak) are allowed in the Stock class at Sid's Raceway as well. Based on initial tests, they have slightly better bottom/midrange power but a "tuned" brushed 27T motor seems to have more top end power.

I am awaiting my LRP 13.5 so I can do a proper review on it.

I think:

6.5 = 10 turn
7.5 = 12 turn
13.5 = 27 turn

I agree with everything that's already been said about the 13.5. I would just add that it obviously has less fade than brushed stockers, which makes clearing the doubles at the end of a stock truck race a little bit easier.

IMO, BL LRP is the way to go for 1/10. I've had 3 speedos and 7 motors and they all have worked flawlessly. The Vector series motors w/optional sintered rotor feel like well tuned brushed motors.
