fitting bigger capacitor to tekin rs pro? or glitch elsewhere

[johnnygibbon]

hi fellas i have just put a 2nd hand tekin rs pro in my xb4 however i found that yesterday it was glitching with my savox servo an the reciever ( spectrum) was flickering on an off. endpoints are set corrctly as well
i tried 2 recievers and it still did it . i had tested the tekin in my drift car beforehand and it was fine working order
then i added a capacitor to the reciever ( glitch buster) which helped until the latter part of the race as the batteries lost a bit more charge and then about 4 min in to the race it would glitch again and turn off and on again
i thought it might be the savox but its pretty new and has worked fine for months
however on closer inspection this morning i found the little silver capacitor that comes with the esc had come away on 1 leg so was not connected so .......
1. could this be the source of the glitch or does it not make much differance , as i said the glitch happens when the batteries get to about 8 volts near the end of the race and while doing a lot of steering on throttle
2. i am going to replace this capacitor with a new one , but can i replace it with a larger one or 2 wired together to increase the capacity and help prevent it drainig as quickly under load
3. what capacity is reccomended for the power cap for the esc and for making a new glitch buster

thanks in advance
