Need a test controller that is used on a Newbright vehicle. (Beach Park)

Looking to test my 49 MHZ Newbright vehicle to see if my remote is bad.
Just looking for your remote and or vehicle to test my vehicle or remote.
We could test it in a parking lot somewhere.
Should only take 5-10 minutes.
My vehicle creeps forward when it should be stopped.
If I push the trigger forward a little, the vehicle stops, release it and it goes forward again without touching the trigger.
.
My vehicle and remote are 49 MHZ has a 4 channel remote.
Thank You.
