What will happen to the rest of the D3.5 motors such as the 13.5T motor next year? Will it still be ROAR legal?

If I remember I believe it has 30* built in at 0 on the end bell. And each mark is 5*. I haven't had an original revtech in years.

Only the 17.5 will become illegal as of April. The rest were never in question and will still be legal.

Ok thanks. I am setting up for a local race. The race is tomorrow at 7. What do you think is a good 17.5 for boost racing? The track I race on is very technical with one 40' straight.

I run mostly orca stuff. I haven't boosted my 17.5 but my 5.0t is nice with it. I ran boost on my killshot HT stator with HT rotor and it was good also. The HT killshot with HT rotor is great on technical tracks has a ton of low end and you can gear or boost it for straights.

Talking Result of my night with the Revtech

Hi I raced with my Revtech R-series Maxzilla 17.5 motor with 12.5 HT rotor. I used a Speed passion Reventon Pro. My FDR was 5.57 (78/28) in my Sakura Zero. I had the motor one mark on the + side of the timing from the stock setting. My Esc was set up with 6 ddrs, 100% HB timing, 120,000 Max timing. I came in 2nd in the A-Main in Mod class. My Esc temps was 106*F without a fan. My motor got to 149*F after the 7 min A-main with a heat sink but no fan. The motor had great torque, and good top speed. I also didn't have any motor fade. I am very happy with this set up and plan to run it for the season unless I can find a motor that does better .

I ran a new killshot 13.5 (blinky) RPM stator last meet. motor temped at 130DegF for 3 runs on the fourth run i smoked it at about the 4.5 minute mark. temped at 167F after i got it back to my pit. times stayed conistant throughout the whole run so i had no idea it was about to blow untill it happened

Just trying to figure out why it smoked? especially after coming off at 130* all night.

I run a medium ashphalt track low to med grip
3.6FDR
standard can timing (40* i think)
Orca VX
We run at night so ambiet temp would have been 18-22 deg Celsius and it was getting colder so no chance that the grip came up and caused the failure

My guess is the insulation wore off a wire and shorted. I had 2 Revtech motors go up the same way and heard several did the same thing at On-Road Nats earlier this year. These are very fast motors and when you get one that does not short you'll be very happy with it but it's crap shoot. I real wish Trinity\RevTech would fix this issue.

What is the idea killshot motor for blinky touring car Rpm or high torque?

Also would one be better than the other in boosted 17.5?

Last time. Ran touring I was using revtech with ht rotor 12.5 mm

Small track with tight turns = torque
Big track with more flowing turns = RPM

Is it more common to use a 12.3HT rotor for 17.5 blinky 12th scale on a med size carpet track? I am running a 12.5 HT now and I hear the 12.3 would help carry corner speed and still have great torque out of corner.

For the RPM Killshot, I would suggest the stock 12.3BP rotor.... I have found it to be faster than the 12.5HT in most cases, but it is slightly harder to nail down the timing/gearing. It seems to have a narrower window than the 12.5HT.

Thanks for the reply.

What about for the D3.5 motor? Is the 12.5 HT still the best to go with the 3.5?

I raced the revtech again friday night. The only settings I changed was the max timing to 125,000. The motor ran good, but in the A-main the motor got up to 180*. I didn't notice the motor fading or it acting funny. After the A-main I moved the max timing back down to 120,000. Then motor ran much cooler then. I guess it had to much timing to get to 180*. I still placed 3rd in the A-main.

While I have buddies who love the stock 12.3BP rotor in the D3.5, I have had my best results using the 12.5HT.
