I ran my new LRP Quantum for the first time this weekend. Wow, this thing is small! It replaced an old Cyclone TC and worked very well in stock class in my XXXS. Had lots of punch and was very smooth. Setup was easy and changes were noticeable on the track. Day one, so far so good.
Next week I will run one stock(xxxs) and one mod(MR4tcS) with a 10d and will see how it works.
