barts71m,
Not sure you can send the motor anywhere to get the etching. Might just have to bite the bullet and purchase a legally marked motor.
Like Tony, I have a heap of Mini gear that I tested which is now illegal to use. I will be doing as itchyb said and use in my 4WD Mini.
Concerning batteries, I would only consider purchasing or using those approved by ROAR, saves a lot of heartache in the end. With the new BL systems, using LIpo's after a 5 min heat you are only using 1400 Milliamps. So they are also frugal on the batteries. Takes about 20 min max for a recharge.
Tony thanks for the aussie mini thread.
Regards,
Calvin.
