Yep first tank, tomorrow the 2nd and 3rd tank. I noticed the factorysetting was fairly rich for the LSN.
Anybody know what the standard factorysetting is for the HSN?

Just a word of caution....I wouldn't be revving it quite that high so early in the break in. These engines are TIGHT. Just adds unneeded stress to it. I usually heat cycles it at least 3 or 4 times on the first tank or 2 and then start revving up slowly to @ quarter throttle.

HSN should be @ flush with the housing from the factory if memory serves me correctly.

+ 1 you are putting to much stress on the rod bushing. Take your time on break in and it will last much longer.

Thanks for the tip but ho many turns out is the factorysetting of the HSN?

I start with both needles flush with housings and tune from there. Never really use other peoples setting because due to climate/ temp differences , tune will be slightly different. Sorry for the vague reply but that's the best i can give you, i don't count how many turns on the needles. I'm sure someone else will give you there needle settings.

WHOA...that was the first tank and you were reving it like that and letting it sing for that long....I can see that motor giving up a rod soon. Like said earlier with the pinch these motors have your putting alot of stress on the bushing. And reving it so high like that is a good way to spin it.

I have been running nitro cars for over 25yrs and have never broken a conrod even though I revv it sometimes but it is better to idle at the first tank.

Understood, just realize these Alphas are tighter than your average Nitro engine out of the box ;-) We all have our own break in methods...and they all work. These little Taiwanese engines are not your average nitro engine though. Just take your time with them. My first one took just about 2 gallons to break in...my second....nearly 2.5 gallons. It's a slower break in than others I have done for sure.....but they seem to last a bit longer as well (at least in my experience).

I hope that vid wasnt your first tank. I was told never to take it past half throttle when breaking in a new engine. One that is hard to start too. Let it heat cycle and repeat. Follow the engine break in thread at the top.
