Airtronics MT-4

[TimJohnson]

Has anyone tried to use the Airtronics MT-4 for crawling?

Pros/cons?

Thanks

Yes, they have been well received. Do a search for MT-4 in the subject line, I know there are threads here. One of my club members uses one.....he has been happy with it.

I have one and very happy with it. it has lot of features for crowling setup. easy to program, DIG could be assigned to any switches or a lever. also it has telemetry . I have one problem of getting actual battery voltage cause ESC is always providing 5.7V to my mt-4 receiver all the time whatever number of cells you have. if any one could help the please let me know.

I really like my MT-4, it was a bit of a challenge to set up. I am running a 2c lipo right into it with no issues. I am using the lever for my proportional with the dual esc's. great control and response. I wish the throw of the lever was a bit longer bit it just takes a bit of practice. It is a huge step up from my punkdig and DX3e.

I'm using the SW1 as DIG, cause mainly I need to lock the rear diff.

Beat radio I've used for crawling. Especially for proportioning if your using dual esc's

ESC's only send out 5-6v so they dont blow out rx bec's.

The MT-4 stock RX will handle 7.4 into it so your best (and probably only) option is to use a BEC set at 7.4. Use Aux2 port on the receiver for the bec if you have 2 esc's.

Great tips but what if I'm using a single ESC ? am I still able to set my ESC output voltage to 7.4V ?

ESC BEC voltage is usually not something you can set.
The comment was to use an external BEC set to 7.4 volts, then plug it into the RX using ANY open port.

On page 11 at the top under transmitter battery options it says :the operating voltage range is from 4.0-9.6 volts.

So a 2c straight into the TX is not issue at all.
