Exclamation Nwebie Nitro questions (HPI RS4 Evo)

Hi everyone;

I just bought a new RS4 Evo RTR
In followed the instructions to the letter, but had trouble starting it.
In the manual it showed putting the glow charger on the glow plug, but did not say anything about how long (eg untill it starts, for 10 secs, etc). If I left it on there it would start, but die shortly after taking it off.
Also, while trying to start it, after turing over for a few secs (with the roto-starter) it sometimes would (seemingly) seize, or stop turning. I never held it on there once it stopped. I only let it turn for 5 secs or so at a time.
After I DID finally get it to idle, it would die, as soo as I tried to apply even a tiny bit of throttle. (Also, the wheels were not turning as they should, almost as if there was brake or clutch drag, but I don't think so, it rolls freely).
I let it sit a couple hours, because I thought it may have been flooded, and the roto-starter was turning VERY slowly, as if the battery was not charged. So I charged the battery for the roto-start, while I let it sit for a couple hours.
When I tried to restart it again, the roto-start failed, it actually smoked where the extension piece fits in to the roto-start, and the battery got real hot.
I am a couple hours away from the dealer where I bought it, and am wondering if I can just use the extension piece in a drill, or use something else.
If there is a link to find all this info, I would be glad to read it.
Thanks for any help.

Default Update-More Info

It is getting fuel, no air in lines.
I looked at a similar post, so am going to target to buy a drill, try that.
It was properly primed, the Evo has a primer.
I am using 80 percent nitro.
Please someone tell me how long I need the glow plug heated for!!!!!!!!!

check the starter batteries' connector. is it black, or melted? is it a cheep tamiya connector?

also, make sure the engine isnt flooded. have a good ignitor battery.

good luck!

Red face RS4 Problems

Thanks for the reply, the battery connectors are not melted, the stater itself smells burnt inside though (where the rod goes in, where it smoked)
Can you tell me how long to heat the glow plug before I start it?
Thanks again

The glow plug should heat up instantly (as long as the ignitor is fully charged). Leave the ignitor on the plug until after you have started the engine. It sounds like you're running TOO rich (too much fuel, so that it 'drowns' the engine when you give it throttle). Try leaning out the mixture (turn the high speed screw to the left in 1/8" increments. About the roto start-a guy at the hobby shop where I bought my RS4 said that roto-starts are infamous for shorting out, and if that was to happen, to bring it back to exchange for a new one...I'm not sure how true it is, but mine wasn't defective ::knocks on wood::
