I have a T-maxx with the TRX 2.5 engine in it. The engine doesn't seem that powerful but I can't find the specs on its horsepower. I'm wondering if the SH .28 Pro engine would be a good replacement for it. According to the manufacturer it has 3.5 hp @ 28,000 rpm. Would this engine be more powerful than the TRX 2.5? and would it fit in the T-maxx correctly?

Here is a link to the manual for this engine: [link=http://media.hobbypeople.net/manual/147012.pdf]http://media.hobbypeople.net/manual/147012.pdf[/link]

Thank you.
