Hi all,
Just a few notes on the problems I had with one of our members boats.
The boat is a IMARA tug (single screw) with two channel radio, one Hitech 610 speed controller, a blower motor and two 12v 7a batteries.
The first problem was on the bank ampage was 1.5 amps in the water 15 amps.
First thing gear the motor 4:1 with a home made gearbox (ampage now down to realist level), speed control now a viper 15amp
Tried the model, power ok but no radio range
Got home and checked the radio, transmitter 40mhz am, 40mhz crystals, 27mhz am reciever. range 6 ft (didnt believe it could work like this)
tried my 27mhz transmitter and crystals no problem
The transmitter is a futaba but no frequency is written on the case.
Anyway in future If I fix (or attempt to) I will check
Transmitter frequency
Crystals
reciever frequency
has anyone else had these problems
