2nd flight, and a question.
 


Had my second flight today with a 5-10 mph cross wind and they plane flew great. didn't have any trouble landing exepct missing the runway by10 fleet in fronthttp://www.rcuniverse.com/forum/js/f...ngue_smile.gif. one thing i did experiance tho is my plane wants to tilt to the right, it may need some adustments. but i do wonder, How much oil should the engion spurt out? when i was done the entire right side of the plane was covered. also when i noticed i was to miss the runway i gave it full juice and the engion died, could my engien be too rich? (its amagnum XLS-61A) i do have it set alitle rich cause this is like the 6th time iv started it.</p>

It sounds like you are running a bit rich, I would lean it out and do a pinch test, even better, have an old pro at the club take a look at it, you may need to adjust your low end andustments.  A 2 stroke will leave a good amount of mess on a plane.</p>

Hope that helps</p>

i dont belong to a club mainly cause im too busy to enjoy one for the price. i fly out of my back yard since i have about 60 some acers to fly around with a smooth lawn to land on (i live on a farm). but i do have a family friend that loves the hobby and he did get me all set up and answers questions. i was just wondering wat you guys thought or suggested. thnx :) and keep them coming :D

Yes sounds like you're running a bit too rich but perhaps Lean it some then hold plane vertical (carefully) it should lean out some if too rich. It takes a practised ear to tune an engine which only happens with time.

Hey man yeah sounds a little rich only because of the engine dying when you hit the throttle quick.. but yeah, a 2 stroke glow engine will pretty much cover your plane with oil haha just whipe it off as soon as you get back to the pits

yea it sounds a little rich, start it run it up to fullthrottle for a minute then pull it down to idle and let it idle for 30 seconds or so and then push it to full throttle, if it boggs down trying to idle up the low end needs to be leaned out. try this till it has a smooth transition. on the high speed needle, run it up to full throttle and close the needle till you hear the engine at peak rpms then open it back up an 1/8 to 1/4 turn and fly it and see how it does. Your always going to have a mess down the side of the plane, thats the one draw back of useing nitro. hope this helps.

Toothman:

Sorry to hear you cannot learn at a club, which is the best option.

I would like to refer you to two websites that contain a lot of useful information about adjusting your model to fly straight (timming) and about adjusting your engine (tunning).

http://www.gettingairborne.com/engines.html

Also browse other articles posted in those websites about landing, etc.

Yes...expect your plane to be covered with oil after a flight or two. Tilting could be your aileron trim or just the wind. I know most of these guys said it sounds rich,but dont be surprised if its actually lean on the low OR high end. The "general" rules of thumb for low speed needle tuning is...

If your at idle and punch it,and it dies immediatly.....low end is too lean.
If your at idel and punch it and it hesitates then takes off.....low end is rich.


Now if its REALLY rich (low end or high end or combination of both) it may die too by simply flooding the glow plug with more fuel then it can burn up and drowning it out(maybe your case),b ut usually if this is the case,most experience pilots will be able to detect that the engine is out of tune right away after starting it and warming it up.

Good luck!
