I have about 6 Dumbo tx/rx sets. They were bought to replace my STX2'S and TQI'S. As a stock replacement, they do quite well. Steering response is much faster than the STX2 and the range is at least double what the TQI can do.
There are only a few things to be aware of...
- Analog controls. Some escs dont calibrate well with analog settings. Using one with my Tekin RSPRO made a twitchy, uncontrollable mess.
- Steering trim is backwards
- Steering trim will drift. Turn your car off and back on again, you'll probably have to check and reset the trim. Also if you leave the car running for 5+ minutes. I'm always fixing trim with Dumbo radios... my biggest complaint.
