I have had two Trinity Picco's, both .12's, one a standard exh. and the other round-side exhaust. The later was an extremely powerful engine and very easy to tune. More than once my XXX-NT wheelied over backwards down our 120 foot straight with the engine running at 205 degrees. But... Since there is no real distinct power advantage between the top of line engines out now, go with the cheaper, ie. Fantom.
