Try em all....and judge for yourself. I recently went over to the "Dark Side"...prop in the water boats. My poor airboats ( I have two Airforce...the other one hasan OS .55AX with the samesize prop)justs sits now....but I will firethem up one day...I am so consumed by my new boats....a Deep V mono and a Hydroplane. I am going to give my brother one of the airboatsto have someone to run with and I am excited about your boat. You could say I have the best of both worlds...maybe....but your progress will speed up my renewed interest in the airboat hobby as the other boats engines ae very finicky at times....and I have had more bad days than good....compared to my airboats.
