Why 3 Channel Radios?
I'm sure this is a stupid newbie question but why are people buying three channel radio systems? One channel for throttle & brake/reverse, one for steering and the third is for ?????
Am I missing something really obvious?
Thanks

Could be a reverse module on a nitro vehicle, or a secondary steering servo or dig unit on a rock crawler...
My friend actually took a motorcycle horn and wired it in his scale crawler using a 3rd channel receiver. You would not believe how loud it is on a little RC car

The transponder doesn't require an available channel...it just uses power from either the battery or auxiliary plug on the receiver.

Some guys using 2-channel radios power the transponder using a Y-harness to splice into either of their channels.

My rock crawler I use it for locking the rear diff
On my gasoline boats I use it for Fuel Trim
On my 1/4 scale Nascar I use it for Front to Rear brake Ballance (just like the real cars do)
And on my Scale boats I use it to turn On and Off light's (MCD switch 8)

If you were the manufacturer, and you wanted or needed to boost your profits to stay in business, you have two direct ways of doing so.
1. Reduce your expenses (cut payroll/raises, cut projects, reduce $$$ on r&d, etc...)
2. Reduce your manufacturing costs.
By making a 2-channel and 3-channel radio and receiver that are otherwise basically the same, manufacturing costs increase. BUT if you decide to eliminate the 2-channel model, and sell the 3-channel model to would be buyers of 2-channel models, you give the buyer increased flexibility while at the same time boosting your profits by reducing your manufacturing expenses.
Simple Economics my friend!

Some drifters like to make flipping head lights. Which is why they need 3rd channel.

If I'm not mistaken, most 2 channel radios are considered 'lower end' by the manufacturers.
Take for example the the DX2.0 and the DX3.0. I don't need a 3 channel radio how ever the DX2.0 only has 2 model memories, so if I want more, need to step up to the DX3.0.
Once you step up to the higher end radios, it becomes a cost control measure I would geuss. It cost more to produce two radios that are the same but one is 2 channel and one is 3. By producing one version, keep production cost down, store don't need to stock more inventory etc...

futaba should definitely seriously consider making the futaba sixpack
