O.S. OS Speed B21AD Adam Drake Edition Off-Road Nitro Buggy Engine
This engine is super high quality but it seems to be the answer to a question no one really asked. Nice, though not much different from the B2101 (not 2102) and not as powerful as the Ty 100% Spec2. I tried it in buggy and felt it has a less linear powerband than the square stroke 2101, then in truggy it didn't quite have the torque I wanted compared to a spec 2. With the B21 Ty 2 and Ty 100% Spec II, those are the buggy and truggy engines of choice in my opinion. No disrespect to Adam because he's a great guy and the engine is still very good. Ran it with 2090 pipe, P3 plug, Byron 30% fuel.
