Chasing small throttle burps and short duration holds can be very pesky.

From my experience (using Castle 45HV and 85HV and a variety of JR PCM recievers and 2.4 recievers) -
- a choke on the ESC lead next to the ESC rarely helps.
- a choke on the ESC lead next to the RX helps the majority of the time.
- moving wires and components around to better isolate them helps on occasion.
- rotating the receiver 90 degrees (in any direction or axis) may help (or hurt).
- type of choke really doesn't matter much - I ended up using an 18" aileron extension woven around itself in a small circle - cheapest and lightest choke, and worked as well as anything else.

Once I changed to 2.4, I've not used a choke, and not found any reason to use one.
