Another week, and yet more fun with reader questions…
“This question is for Cub Reporter,Is it ok to rev my engine real high with the wheels off the ground?????
Cubby- What’s up “Wang”? Seriously, is that your name or did you just sign “Wang” on your email as a cheap joke? Either way, your question is a sound one that I’m certain many a noob has pondered.
You mention the word “engine” in your email, so I’ll assume you drive nitro. In a nitro engine, I’ve seen people break cranks and rods by revving their nitro burners too high with no load on their engine. Now personally I have tortured several nitro motors, mainly after a crash where the nearest marshal was texting with one hand and smoking with the other, so I’d give my buggy the death/panic rev to get their achtung, and I seemingly never hurt any of my engines. So perhaps YMMV with this one on nitro engines.
For you flashlight drivers out there, electric motors have a different set of issues. When you hit too high of an rpm, whether it be under load or not, you can ruin the bearings that support the rotor, or worst case, shatter the rotor from centrifugal force. Some brushless motors now days are good for nearly 100k rpm, others much less. On normal cell counts you might not have to worry about hurting your motor from too high of rpm, but on higher cell counts you might very well be able to blow it up.
And you’re welcome.
