Hey everyone this is Tony Jr from warehouse hobbies, my dad started the business back in the early 80's that has produced some of the best boats in industry. unfortunately he is retiring from the business, I will be offering affordable engine modifications, the same modifications we have been doing to our boats since the zenoha motor came out in the early 2000's I have produced hundreds of race modifications known as the M6 and M5 that are being raced across the united states today... I have been working with my father since 2008 developing faster engines and will continue to do the same for all the R/C enthusiasts out there. I have just recently joined some of the R/C forums to become a little more involved.
