Throttle and engine speed

New here. I have a Spektrum DX2S. When starting my 5B car the engine runs max. Is there a setting on the xmitter?

Find the manual and search for trim adjustments. Since it's digital and i don't own it i can' help you more than that. Your engine may also be tuned lean

Welcome in @elchucko , chances are, it is the throttle servo. With mine, when I hit the brake I would get a very high throttle.

Welcome to the RCT fun house...

Sounds like your throttle trim isn't set properly. Here's a link for the manual for the TX. https://www.manualslib.com/manual/787388/Spektrum-Dx2s.html#product-DX2S

Your throttle trim is on top of steering wheel to the left. Pic of it below..

And the servo was centered again. When you installed the new RX. Sometimes they can become off center with upgrading your TX and RX.
