HOBBYWING Tunalyzer and Tuning a HW 17.5 G4R Motor

[@The_Absurdistt]

As always, wonderful vids. What current draw range would you recommend for a 25.5T? Cheers.

[@AdamDrake]

My pleasure! I'm not sure, but will try to find out.

GREAT INFO thank you Adam

Glad it was helpful!

When you are tuning a motor, are you only looking at the current draw to determine timing? Is there a specific current you are looking for? Is it always 6.4 or .5?

[@AdamDrake]

6.5 amps seems to be the sweet spot for 17.5 motors in a 2wd buggy.

What pinion and spur do you run on your B7 with that G4R 17.5 at 52 degrees? I’ve been at 48 degrees on a 75 31. It’s ok, but always looking for more speed and power. I have a Hobbywing tunalyzer too. Thanks for the help

Are you running on dirt or carpet? I'm running the Mugen Seiki MSB1.

[@CoeShow619]

@ on clay indoor. Tacky good traction. The B7 has a 2.6 transmission ratio. I can do the math to match your Mugen. Thanks for the help.

Is a motor fan necessary when increasing the timing for the higher amp draw? With a out of the box motor and 32/72, I'm running 150-160 after 5 min

[@AdamDrake]

I do recommend a fan for 1/10th racing on the motor. I don't use a fan for 1/8th racing on the motor.

Can you share the part number for the high torque rotor? Thank you!
