Spent a few hours on the water today testing my new setup.
Sv27
Turnigy 2300kv motor
Aquastar 90 amp ESC
Grimracer 40/53 3 blade prop
2 - 2s/2p 5400 mah lipos
75 MHZ AM radio
port side turn
rudder tucked in
stinger parallel with hull
This is the second outing for the setup. Last week a couple of us were out and I experienced some radio problems --- specifically glitching of the motor and servo. First noticed the intermittent problem while the boat was still on the stand and doing some tightening of bolts on the rudder. The servo and or motor would twitch whenever the allen wrench came in contact with the heads of the bolts. It was as though I was sevring as an antenna for some stray radio interference that was being picked up by the receiver. Did a range check and discovered a lot of issues from about 20 feet on out.
Buddy suggested we try his Spektrum 2.4 ghz which seemed to take care of the radio interference problem.
Went home that afteroon and decided to put some fresh batteries in the transmitter and did another range check in my back yard. It's pretty spacious. Everything wroked well beyond 100 feet and concluded that the problem was resolved. . . . . until this afternoon. Dropped the boat in the water and it ran fin for the first 50 feet before both servo and motor started acting eratically. Rescued the boat and did another range check. . . . with the same result as last week. Swapped radio and receiver with a spare that buddy had brought along with him with nearly identical results. Retrieved boat a second time and swapped radio for Spektrum. The boat ran well and we were able to test a couple of different prop setups and corresponding temps on motor, ESC and batteries.
Reflecting on the radio issues it appears that the failsafe is working properly on the ESC and that there is some significant interference to the lower 75 mhz band while the 2.4 ghz remainds unaffected. I am arelative newbie to FE but have some technical background and am trying to understand and or isolate the problem. Anyone encounter similar issues?
Apart from the radio issues I loved the way the boat ran.. . . and enjoyed the whole exercise of trying to establish a baseline for operating it efficiently. I don't have infintely deep pockets so I won't be trowing a lot of money ino this setup. I want respectable speed combined with reliable operation of all systems. My new-found nitro buddy suggested I consider switching to a smaller prop. We had tried one of his spare two-blade ones but ther seemed to be significantly more cavitation along with reduced speed. One thing I plan on doing is saving my pennies for an affordable 2.4 GHZ system over the winter..
