You can also do the engine replacement program that HPI has. Can return any engine and get another G3.0 for 65 bucks.
hmm, didn't know HPI had an engine replacement plan, with that in mind I would consider doing an engine replacement if money was an issue. The 3.0 is a decent engine, but if you can spring the extra cash I strongly recommend the OS18 as it provides an incredible amount of power to this truck, much more than the 3.0
