The leg... is not necessarily... (at least in my experience) but the band is always negative...

you can actually store profiles in your pocket pc using text files. but you wont be able to transfer it. you will still need the handheld programmer to program your VFS.

There are some settings on the previous pages on the thread. The best way to add punch, is a combination of larger capacitor and profile adjustment. At least that did it for me.

Default Using a 5 Cell RX Battery Pack with VFS1

Hi

I am just installing my VFS1 (J) into my 1/12th scale. I use the mini KO 302F reciever.

When I run 4 cell 19Turn, everything is powered from the main cells... however
When I run Mod I install a 5 cell pack with its own switch. I find this makes things less risky if I dump and avoids issues with Personal Transponders dropping out.

My question is about what happens to the VFS1 in the latter case. I am worried about the BEC in the speedo and my little RX batteries tring to power at the same time.

With my old Nosram Dominator Evo I did not worry about it. I turned on the RX battery switch and avoided turning in the speedo at the speedo switch when using the RX pack. I have accidentally turned both on with no ill effects but I don't want to risk that with the VFS1 unless I know it will be fine.

Please advise

Thansk and Regards

Mark

Mark-

When using a receiver pack, you must pull the red pin in the lead going from the esc to the receiver. DO NOT CUT the wire. You will need to re-install the pin for programming the esc. I would recommend using heat-shrink or tape to make sure that the pin does not short out against anything.

You will still have to turn on boht switches. Turn on the receiver switch FIRST, then the esc.

Thanks for getting back to me so fast Robert.


.... oh, thats a pain! I guess I am going to damage the BEC then if both end up connected?

And another question if I may.... Am I right in assuming the Battery Save voltage should be 2.3V for the 302F RX?

Am I right in thinking that if the battery voltage falls BELOW 2.3V then the speedo will take over the throttle response and overide whatever my stick is commanding in a bid to restore voltage (and keep control)?

Thanks again

Mark

Mark-

You may damage something with both connected.

The battery save voltage can be set to 2.3V ONLY while using the KR-302F. When the voltage falls below the set value, you are correct.
