Yep, you could expect 1.5 to 2 hours runtime on the same 2200 3s pack. That's what I get on slower rigs with that size battery.
How does a CrawlMaster 540 13t have the same wheel speed as a TorqueMaster 540 27t?

Different slot counts, both are two pole. Higher slot or pole count = lower turn for same speed. That is why four pole motors don't list the wind in many cases, it just confuses people

So the two motors I listed are identical? But the CrawlMaster has slightly better low speed control and the TorqueMaster has slightly more power?

They are pretty close in speed. Torquemaster makes more torque (less bogging down), crawlmaster is smoother on low speed power delivery.

I purchased my RR10 Bonber to bridge the gap between the Wraith and the Yeti. In stock form I wasn't impressed but in brushless sensorless configuration with 2 speed transmission I'm enjoying it. I prefer it to a sensored system running stock transmission (2spd not usually needed with sensored systems) because of the crazy torque twist. The higher gear ratio I can use gives me low speed control, tons of drag brake, and limited torque twist in lo gear. When I want to go fast (14mph lo, 24mph hi gear) I can just upshift. No biggie

I'm considering something slower now. Something faster than my Traxxas Summit (16.9mph in high gear) so something around 20mph hopefully. I want my platform to be a "Wroncho" or a Wraith. I'm still deciding on the motor but I do like running in the 20mph range even for something more crawling oriented with some trail running ability.

It'll probably take me 2 months to decide on what motor to run like it did with the Bomber

I'm leaning towards either a TorqueMaster brushed or a TrailMaster brushless. I've had great success using a cheap hobbywing 2pole motor and I've heard your 2pole motors are even better than the other 2 pole motors. Any thoughts?

Sorry Let me state it as "no load draw"
Or the amount of draw under no load.
