I have 2 DNA200 Reuleaux that have issues. 1 I put the batteries in it sparked up and now doesn't work smells burnt. 1 When I load the batteries in and fire it the screen flashes on then off right away. On both the mods i noticed the battery sleds i cracked from top and bottom in the same spot. So I know that's a common thing because i had multiple people tell me they have the same issue. So my question is where do I send the mods to get fixed up and running?
