Want to take a second to thank Monty for taking the time to answer all my questions during the purchase, break in, and then tuning of the X5. We ran the X5 over the weekend at the RC Pro Series race in Belton, Tx. and it ran flawlessly, had lots of smooth tractable power, and good run time( even with the 8mm restrictor, hot plug and conservative tune ). If you're looking for a good race engine and great customer service give Monty a call!

TQ and won the Int. Buggy A not bad for first weekend with HES power!
