Help a rookie?

I have not formally introduced myself, so I will start there.

My name is Timathy. Tim is fine

I have had a deep love for RC for a very long time since I grew up around my Uncle who was a complete RC nut. He even owned an indoor dirt track at one time. I used to love the rare occasions I got to play with his RC10 gold pan, Frog and Hornets. (those where the ones I was allowed to play with :O). Anyways. I have not had the means or the time to get into it myself until here recently.

I have a Leo x I had purchased a long time ago. It has bearing set and a hop up motor of some type. They where out of fireballs at the time. That truck has been broken for a couple years now. I hope to be getting a rx unit off of Russ here soon

.

I also Own a Redcat Sumo Truggy which is my sons. It has the 180 motor as well as bearings and steel universal drives. Its a pretty fun little beast.

Now comes the problem... I also own an Xmods street/evo with a PN 50t motor, AWD, bearings and the list goes on... I know, I know, Should have bought a miniz... But I didn't and here I am lol. To make a long story short My board got messed up and I ordered a new one. The board I recieved after hooking it up will only turn 1 way and not even center. I tried replacing the steering fets with the ones from my old board. Which did steer perfect. Still the same. Does anyone have any idea of what I could try? I am at wits end with this car. I do not have the money or I would just do the miniz conversion.

Any help at all would be great. Thanks
