Futaba 3GR-FS

[chris harte]

If i was to use the Tx with a 4 channel receiver could I use the 4th channel by using a switch on the TX even though its only 3 channels?

what car is it for?

what car is it for?

It will be for use with a king hauler truck. I don't fancy spending an extra ninety + pound for a new TX.

will it have mfu (multi fuction unit) ?

Yes thats the plan to fit an MFU

hi again

Everything will need to be 4 channel

[chris harte]

If I was to run the kit on 3 channels what could I use the 3rd channel for without the MFU unit.

Im not 100% sure even though i own a 3speed high lift and scania truck. it would be best to ask on www.tamiyaclub.com/forum

they will give great help about trucks etc

ive just remembered.

1st channel = speed controller

2nd channel = steering servo

3rd channel = servo for gear change

[53HRA]

one question...does the futaba 3gr-fs have digital trims?

if so then theres a probelm-the transmitter has to have manual trims else it wont perform as good as it would with the mfu.

Cheers. I thought it might be something like that.

Does it auto gear change with acceleration on the TX or do you have to stop and press the 3rd channel?

its like a real car!! you change gear from the transmitter.the left stick doesnt go up and down like the 2 channel-it goes in a gear pattern.

like this:

clicky

every 4 channel transmitter will be like this.you have to buy the gear guide seperate-this will stop you gear grinding as its a guide to show which direction to change gear in .the top 3 are 1st gear,2nd and third.the bottom is 1st,2nd,3rd but reverse.

Ah that makes sense now.

I will have to get myself a 4 channel tx to use with the truck.

I can't wait to get a truck. I have wanted one for ages.

just to say...it has to be 27mhz or 40mhz.35 is not allowed in the uk

[chris harte]

Yep it has to be 27 or 40 or 2.4GHZ. 35 and 72 are not allowed as the military use it.

enjoy building the truck(it takes around 11-14 hours)

[chris harte]

Thanks. Is there any particular problems that runs across the range of tamiya trucks?

Do you need any particular spares also?

ive never heard of there being probelms with them(as long as you build it right) and i dont think you need any particluar spares

tip is to empty the parts bags into little boxes because the parts are all over and it just makes it easier

When getting the radio system remember to get one with manual trim, you can use digital trim but its alot slower
