I still think there is a problem some where but for now I will keep trying to fine tune.

Cool, I had a problem with my Losi today where it would idle high and I couldn't get it. I ended up starting over from some base settings I know are good enough to run, but not dialed in. After a few minutes it was running great again.

I find it ironic that this thread is RIGHT NEXT to the OS engine thread... (or at least it was until I posted) :lol:

:lol::lol:

I find it hilarious :ha: that some are trying to keyboard diagnose the guys problem and then arguing with each other about it when clearly the fix was in the first few postes. Bandwagon-ers on the first few postes:nod::lol:

What I find funny is when someone posts "I have a problem with my engine." There are people who jump right to "you have an airleak! take everything apart!". Most of the time it's just wrong tune. Starting over and reworking it will usually take care of it, especially if it's all new gear.

That wasn't me and I agree, you see that crapin'in all the time:lol:.. Air leaks are over rated.:tire:

what would blow me away is to fix an engine problem on a chat forum! :lol:

Actually adjusting the mid range with the lsn and idle helped. I may be new to nitro but I can work on anything and understand mechanics very well. I like to ask questions when something is new instead of just assuming something and then blowing up a new engine. All the suggestions have helped and I hope after tomorrow it will be all good. Thanks for everyones help.

Hey in the end regardless of what anyone says this is a hobby. Hobbies are meant to be fun and enjoyable. As long as you enjoy R/C then all is good.

pitpop I understand what you're saying, but there are some very common mistakes that people make with Nitro engines. These mistakes have easily recognizable results (high idle, won't idle, bog at wot, bog at low throttle etc). Those problems can be diagnosed through trial and error and someone who doesn't know what causes a particular condition, would do well to ask for advice on things to try. If it doesn't work you can always turn the needle back to where you had it and try something else.

The biggest thing that I have learned with nitro so far is how small adjustments can make a real difference in tune. I printed off the tuning bible as well as all of your post and it helped alot. Thanks again to all who have posted.
