This weekend I might start installing back all my led lights..I used the new body cover so I have re drill all the holes again for the roof led lights.as for the extending the rear bed I have removed the bed top of the old cover and trimmed it all up.but I'm also liking the back naked .kinda like the open end look .gives it that drag racing look.and I like that fact you can easily see that aluminum center brace showing .I even thought of making a whole top bed from lexan and wrapping it in carbon fiber wrap and leaving a 3" by 6" square in the middle just clear and installing red led lights inside the chassis.like a little window glowing red.with the Arrma forum sticker on top .I strongly might do this .any thoughts plz send them my way.👍😁stay tuned .more coming I promise

I’m guessing a lower kv motor with a higher voltage rating then you can get high torque and gear up for speed🤷‍♂️
I’m not experienced, just an idea from reading, hopefully smarter people will also comment😂

I was allways under the impression that a higher kv motor would give me more power.🤔

Higher KV means more rotations per volt. This means your motor itself will spin faster. Then, you can change gearing to get your final drive back up. If you can get a matching final drive, a 1100 kv motor should have the same overall car speed as a 3000 kv motor. Then, the 1100 kv motor would have more torque, and equal speed to the 3000 kv motor. This is why the top speed runners use lower kv motors.
@LibertyMKiii has way more knowledge than me on this topic, but I’ve learned a bit from reading his posts! There are many others, I’d also suggest talking to @vwturbowolf i believe he has some great knowledge about motors.

At some point though, too low a kv and you won’t be able to adequately gear for the speeds you want. There are websites for checking speeds and gear ratios, but I don’t currently have a link.
