    Back in the '70s i paid CAN$400 for my 1st 72MHz 4-function radio setup for a STANDARD CLASS glider, 100" span. I journalled the build, it took over 90hr. Today i get a 6-function 2.4 rig for CAN$50 from Amazon, then add $20max for a good rudder servo. Gliders dont require an ESC so the comparison ends there. My hobbies seem to get less expensive as I age.β›΅

    As we age Rc gets less on aircraft Boats what can happen wrong? It turns left not right but no crash

    My large high speed glider went straight down liPo but like pretzel but didn’t explode or open. I blame the receiver but not so sure it wasn’t me. Boats are safer bet n less clean up on damage. Now where did I put that electric jet engine fighter?

    Hhager2 thanks for that detailed explanation. I gave up 72MHz aircraft 7yr ago when i lost the hand-eye co-ordination & my salvation has been RC ships (which crash only in 2 dimensions, not 3). Your tech explanation warmed the cockles of my technical heart. Two point four has been a blessing to our hobby in many ways...radio apparatus is relatively inexpensive,& rechargeable batteries in the TX hav been replaced by a few AA alkalines which seem to last an entire sailing season. Additional receivers are inexpensive. The drone industry has brought us less-expensive servos & ESCs not to mention LED lighting strips. LiPOs scare me but SLAs & NiMH pks do the job well.

    If you have a Spectrum set you have no worries, this receiver has NO Ariel to bother with.

    Cheers, Pete

    Remember 2.5 ghz is attenuated by water rain too. It can penetrate buildings at times. Airplanes have height advantage n clear areas once in air. Boats can go behind vehicles or land which can attenuate signal. There is usually a fail safe mode that you program. In aircraft it’s straight ahead n motor off. Slight nose up. On boats you can set for a wide circle or motor at half? I have Rc aircraft that if signal is lost it returns to take off point n manages itself to auto pilot land. It would be good if a boat could return to launch point on auto pilot. Gps gives that ability in Rc heli n planes. It could apply to boats?

    Most 2.4ghz rx's have 2 short Antenna, one should be vertical and the other horizontal. I often drill a small hole inside a flagstaff or mast NOT METAL, or even position the receiver in the funnel.
    Hope this helps, cheers Colin.

    2.5 ghz is diff from MHz radios The antenna is very short and can penetrate the boat easily if it’s inside it. Metal is a problem I have a spektrum radio one receiver fir gliders has a long antenna the rest are tiny couple inches. If you wanted to put a long antenna line I described inside a plastic pipe that works. Otherwise the radio with short antennas can go inside the model. Do a range check in either case to make sure. Btw 2.5 ghz won’t work under water in a sub. MHz radios can get a few feet under.

    Surface craft at ghz work fine with radio just placed inside model
