TO ALL SPEKTRUM RC BOAT OWNERS: I am inquiring to all boat racers if you like spectrum radios and if you have had any problems with them? The radios i am interested in are the new 3-4 channel radio. My understanding from Horizon Hobbies is that all SPEKTRUM surface radios are designed for cars and NOT FOR BOATS.The SPEKTRUM 3-4 channel surface radio packages come with two receivers no servos and the receivers can't be used for racing boats. So you must purchase a $80.00 MR3000 receiver for boat racing. Is anybody using these radios with the MR3000 receivers and have any problems? Are they worth the investment? I am aware that JR no longer makes surface radios for cars and boats along with there servos. I am not inquiring about Futaba,Hitec,Airtronics,or Flysky,or JRpropo you all have your brands you like. I am trying to see if the $350.00 SPEKTRUM package plus 4 receivers $320.00 = $670.00 is cost effective for 3 boats to run. Yes one extra receiver for backup and still no servos. Any comments are appreciated. Thanks Dan Mccormick ---NAMBA 221
