Good speed & above 100oz/in is good for a 2wd buggy, maybe more torque on high grip. Coreless or brushless motors + digital work better for holding power, return to center and resolution but you’d...

Adding power will hurt run time. A lipo upgrade will improve run time and power. Small nigh batteries aren’t very good for high current loads. If you have taller tires, lowering your gearing will...

Theyíre not forcing anything on anyone. Theyíve just moved to a faster better protocol. All radio companies have. Luckily, new Spektrum rxís are pretty inexpensive.

They work fine. Some radios won’t access their fastest frame rates with analog servos but they shouldn’t hurt the servos, either. I’ve used really old Airtronics 257’s and 258’s with newer Spektrum...
