Ive got an older lrp sphere. Its not the tc. Ive been racing my nitro buggy latly and not playing with my brushless stuff. Im looking at adding a 13.5 brushless motor to y t4 and start running it. Will the newer motors work with my speedo?

Good Speedo...Any sensored motor down to the Sphere's turn limit will work. A Novak, LRP, Tekin or other sensored 13.5 will work great.

I bought it as a combo when they 1st came out. It came with the 4 star which I ran dirt oval and it was very fast.
