I have 3 engines for sale that are in very good condition ,I just don't have the time race anymore and decided to let these engines which is hard to do but thats life! I'm asking for the OS R2102 $175.00 ! Now the Modified novarossi Ison is going for $165.00 it's in great shape with very little run time! The Kabuto R21 is going for $165.00 my engines are taken good care of meaning they get after run oil to keep them in great shape! My reputation on rctech speaks for itself everything is good
