RE: OS 18TZ vs Traxxas 3.3 Engine Test
The best of the two so far is the TZ mostly because it keeps a tune better. Notice that I had to add the wheelie bar. The 3.3 was fitted to the chassis using homemade motor mounts cut from a 1/4" thk x 3/4" tall aluminum bar stock and drill/tapping holes where everything lined up. CEN'S adjustable motor mount probably also could be used with some height spacers. The Tower ST-15 is a good flywheel to use if you need a very thin one for tight clearances. The clutch bell and shoes shown are CEN's hop-ups.
