Transmitter question
 

I fly planes. I'm wanting to get into Sailboats mainly becuase it just looks cool. I have a Hitech Aurora 9 and I am just wondering if it will work. I know as far as number of channels it's overkill, butI don't want to buy another transmitter. It just seems like a waste of money since I already have a nice transmitter to buy another one.

Thanks

RE: Transmitter question
 

I have an Aurora 9, too.
It will work ok.
I also use the Graupner MC-19.

Although a better way to go is to buy a used Graupner MC-19 40MHz radio and convert it to 2.4GHz HiTec transmitter. This allows you to have marine computer programming and full telemetry of your electronic equipment. The Graupner radio also has aircraft and land vehicle programming.

At the transmitter all the controls which can be connected can be used to control up to 8 switched functions, i.e. switches, trim switches, sticks and auxiliary analogue controls connected to inputs 5 - 10. Two additional Nautic transmitter modules (Order Ref. N&deg;. 4108 or 4141) can also be installed and operated with the corresponding receiver modules (Order Ref. N&deg;. 4159 or 4142). Even in this configuration there are still 9 functions freely available: normally 1 for steering, 1 for forward / reverse speed, and a further 7 functions for any auxiliary functions you wish. They can be operated using either stick functions including trim, or stick functions and trims as separate (analogue) functions, or analogue inputs (inputs 5 - 10 / switches).

RE: Transmitter question
 

A mate of mine faced a similar dilemma last year.  It was pointed out to him that he could get a cheap basic 2.4GHz TX and RX combo for less than the price of the extra RX for his all-singing, all dancing, all bells and whistles Futaba.  Don't know if this applies equally to Hitech.

RE: Transmitter question
 

I use a 60$ spektrum stick 4 channel radio and spektrum waterproof marine rx's in my rg65's.
Although 22$ HK 6 channel radio would do everything and more than the SPektrum does as it's programmable. I race electric boats with a Pistol TX so I already had the Spektrum stuff. Just needed to add the stick radio
Your Hitec will be fine for a sailboat.
That thing listed above is a nice radio but what the hell do you need that for in a 2 channel sailboat? Is it even 2.4?
I'm personally done with non 2.4 radios after having a tunnel hull race boat hit the bank at full tilt, total loss including a broken outboard lower unit! Never had a glitch with the 2.4 stuff, even the guys running the 15$ 2.4g hk radios are fine.

RE: Transmitter question
 

My Graupner MC-19 40MHz tx was converted to a HiTec Aurora 9 2.4GHz tx and a HiTec synthesized 75MHz tx. It has a Jeti 3-position switch for changing signals. I use the 2.4GHz tx for aircraft and surface vehicles. The 75MHz tx is used for my submarines.
The radio has 20 RC model memories and is expandable . The Aurora 9 tx allows the use of telemetry, as well.
The German radios are the best, but I bought this radio at a very low used price .
