My first foray into R/C with my son...

I bought a 4wd Lancia Delta on a TT-02 chassis. It's almost built and I'm just setting up the electrics, and I'm confused! I have an Absima CR2S V2 2 Channel 2.4GHzRadio transmitter and it isn't doing what I'm expecting, but I don't know if this is normal behaviour.

Can anyone help with the following queries?

1- it seems slow too respond. Switching from forward to backward takes a few seconds, even though I let the motor so first with the trigger in neutral.

2- I was expecting the steering to be instant, but it isn't.

3- although I have receiver and transmitter next to each other on the table, it seems to sometimes ignore me.

It had fresh batteries in, I've followed the guide to connect it, and I think I got the setup correct by using the SET button routine.

I am sure it is me though! :-(

Delay between fwd and rev is normal (there to avoid stripping gears by slamming into reverse to do stunts!) and that's usually programmable from the speed controller, not tx/rx

Slow steering could be drag in a linkage? Disconnect servo, take front wheels off and see if steering linkage "flops" on its pivots with fingertip assistance.

Also, in the olden days of RC, we were always told tx and rx should be seperated by a few feet when on, not next to each other (can't remember why though!)

steering problem disappeared once I fixed all the components into the car and put the wheels on so maybe that was it.

and moving the Tx further away from the car solved that problem as well, thanks!!

I'm not always this useful (ask MrsVX!)
