Hi there guys, I have a HPI RS4 3 and I got a .12 size engine in it, unsure of brand considering there is no marking stamps on the block. Now the problem is it starts and after about 3 seconds not even it stalls. I try revving it and it stays on, as soon as I release the throttle it stalls. How can I tune this to be a good engine, it's not that old it's only done about 3 hours of use. What settings should I adjust it to?
Please any help is wanted, I can't seem to get it tuned.
Thankyou so much if anyone can help, much appreciated Paul, cheers
