My Buddies DVX400 dies when he land jumps. It will do it on small jumps or big. Any suggestions as to what might cause this?

 

Does it start up easy when it dies? It may be some problem with fuel flow.

 

It starts just fine. He also hears the starter go off upon impact.

 

Sounds electrical. Make sure there is not a wire being pinched by the suspension when it is compressed. Also make sure the battery is locked down and it isn't grounding to the frame. I had a wire grounding under the seat that would blow a fuse and kill mine. I just bet it's electrical.

 

Thanks for the advice, we'll check it out.
