Hi Bob:
If you've read the other posts in this thread, you know that those V-Maxx's caused many folks many problems. I can't give you an honest answer, as I have a LMH 120 Corona, brushless electric power ... NO troubles, NO mess. The others have contacted LMH and have had no problems getting the engines replaced, including the 2nd, 3rd, 4th and so on. I'm sure LMH knows the engines are a problem, but they don't seem to be doing anything about a more reliable replacement.
Good Luck,
Russ
