ok update: i bought a novak 4700 uf cap installed it today and ran practice at the speedway race here in florida.

4 cells
19 turn
keyence rapida
novak cap

flawless all day!

i even ran the car down to a dead crawl and the receiver never gave up!

so far the cap trick has worked wonders in 4 cell oval for me!

big thanks for sharing a 5.00 fix....i owe you won bro!
