Well, I'm a mighty happy camper today! I just got me LXX booster set w/ the 3.8 Perfection Motor. This was a great deal, as it comes with 2 Skyline bodies (Calsonic & Clear), 3.0 motor, 3.8 Perfection motor, and booster controller. My reviews are below.
The Booster Controller
When I tried out the booster controller along with the 3.0 motor (I switched out the pinion and idle gear), I was amazed. Such performance from a clone is outstanding. Even when you don't use the boost, it's not so slow.
The Bodies
Now, the bodies are just as great. The Calsonic body was very detailed, and cool. The clear body is cool as well, and I plan on leaving it clear, until further notice.
The 3.8 Perfection Motor
What can I say about this wonderful motor? The thrill of going fast has gotten me addicted. Pull off a sharp turn and you're on your side. This motor is FAST. It's not just fast, it's FAST. I had to power walk just to keep up with it. This is a must buy product.
Overall
I'm having great fun with this set. This is the best deal I've gotten since, well, forever. These two products (LXX AM and Perfection 3.8 Motor) have given me great joy. I suggest you guys at least try it out. You won't be disappointed.
