I'm sorry to hear about your troubles.

I bought a Caldera 10E for my son on on his 6th birthday. He just turned 7, runs the thing constantly with 2s LIPO and in a years time I have replaced 2 parts. A broken shock and the initial stock servo that came with it(replaced under warranty).

I have put way more money into fixing issues on my Traxxas Merv (Mini E-REVO). I still love the thing.

1. My son's has been a little noisy from day one. 1 year later still going strong with the same noise.

2. Range has been fairly good on ours. Not sure exactly how far but it goes far enough to barely be able to see it.

3. Never seen that issue.

4. That is annoying and have seen that as well. Usually just need to adjust trim.
