tekin rs pro temp

[fletcher]

hope someone can help. Iv always been a hobbywing\orion user, but after all my gear was stolen last week i picked up a tekin rspro\flux combo from a friend. I wired it all up yesterday. Making sure it didn't get hot as i always do. Gone to use it last night and its generating a lot of heat. By 3 mins in getting a stutter every known and then and loosing power. Its got a brand new sensor lead. I changed the motor, bought the settings right down and bought the gearing down (smaller pinion 23/18, 8.5 to a 6.5 motor in a losi 22) but it did the same. I noticed while soldering it up i did lean on the cap with the iron and it did begin to melt it, could this be the problem? Also if anyone could tell me the caps rating as i dont have my car on me i was going to go maplins and get a new one.
cheers for any reply!
