If I wanted it to be "Click Bait," I would have shown a bikini model and stated she was doing a live review of the motor.

Can we please get the bikini model anyways. P.S. it's gotta be a good bikini model and no hags. Thanks in advance.

Yes. I'll wear a bikini for the next video.

Just a note for OffRoad Junkie and others ... The Double Down series was never meant to be a ROAR legal motor or compared to it. Was developed around the time that drag racing and "outlaw" classes for drag racing were being done back in the 2021/2022 time frame. While it may really loosely look like other Trinity motors, its a completely different design from ROAR based Trinity motors. About the only thing that compares is the "17.5 winds".....

Yes sir. That is what I have been letting a lot of new racers know, when they ask about it.
I remember outlaw motors were not allowed from the days of the Monster Outlaw motors from back in the 80's.

Without starting a new thread, here is what I have done to my minipro. Many of us have identified the inconsistency with the belt drive system so it was great to see the version 2 has moved to the gear drive system. However as the Australian dollar has tanked against the USD, the upgrade kit is too expensive for me.

So here is what I have done. I fixed a spur onto the pulley by tapping 4 m3 threads. The ID of the spur is 8.5mm and I enlarged it to 10mm so that the spur can locate on the flywheel shaft to maintain the concentricity. I have a larger pulley (40t from memory) so the threads stay well within the material of the pulley. If you have a standard pulley (32t) the threads will be very close to the edge of the pulley. Once I have fixed the spur I moved the motor upwards so the motor shaft is closer to the centre of the flywheel. I used a 20x40x2mm aluminium extrusion with the standard mounting location. I ended up using a 42t pinion and 84t spur (48p) to maintain the 1:2 ratio. I can report that it works well.

Now does anyone know if there is a newer
version of the windows software from Minipro for the v3 board? The one from their website is from 2023 and I have seen some bugs with it (eg the power graph).

I don't think I have issues with the power graph. Can you explain exactly the problem you are having, maybe I can replicate it.

It's not that it was banned, it's that it was never designed to meet ROAR specs and never submitted for approval. Outlaw spec racing is popular in Asia.

True. I believe I mentioned that in my video. That's the whole reason they call it an outlaw motor.

I took a Trinity Certified Slot Machine and a Double down then swapped their rotors.

Through all of your testing what are the torquiest ROAR legal 21.5 motors out there?
