Receiver question?
« on: July 22, 2007, 09:51:49 am »

Can a 4 channel hitec receiver be used in conjunction with a hitec 6 channel transmitter, or does the receiver also need to be 6 channel as well?

I know this one............No, unless it has one of those removeable RF module things in the back. Best to get a new set.

Hi Ministeve,

The powers that regulate frequencies in the UK  allocated 35Mhz exclusively for model aircraft for safety reasons. Cars and boats can share 27 and 40Mhz but 35Mhz was set aside to stop surface model users from making planes fall out of the sky onto joe public.

At least that is the reason I was always bought up on.

35 meg is reserved for aeromodellers (legal requirement) . If you use it for a boat or car somebody will come along and shoot you!

IIRC you can still fly on 27Mhz However it is not recommended especially as 35Mhz is solely for RC aircraft (planes, gliders and helis).

When 35Mhz, our local Beatties store (the group closed a few years back) were selling 35Mhz gear with RC Cars! We had a job to get them to stop but eventually agreed(!) to supply only the then 27Mhz band equipment.

Sounds bureaucratic but people have been killed and injured by out of control model planes so there is a good reason for it.

Actual conversion is not particularly difficult or in itself expensive, but getting the appropriate test gear and expertise to ensure a working and legal result is.
The ready built sets come with a type approval which certifies that they are legal for use, and, if unmodified, provide an indemnity path just in case.  Using a modified or home made/modified transmitter must always involve some crossed fingers.

ok so 35mhz is reserved for the aircraft band .
right then what about power from these transmitters ,i have a hitec eclipse7 that was originally on 35mhz  so when i converted to marine i bought the 40mhz module and there we go ,but the thing is when flying aircraft it is done at a range far greater than we would controling a boat so does this mean my tx has a greater output than a normal 40mhz unit??

If is is a type-approved module, this includes the power output.  I did have a link to the appropriate site specifying power output limits once, but it seems to have gone walkabout.  The thing is, if you use a propietary transmitter, it will be legal, not only that, but it will work without any ill effects to anybody else around.

so does that mean the module controls the output power of the transmitter.

 Yes it does , tx on 35mhz and 40 mhz are allowed top use the same power, equivalent radio gear should have the same output, some of the budget stuff can be a bit lower.
