Hey Gang,

I'm new to this great stuff and on my own so I have but one challenge before I take off.

My Evolution trainer that comes with the P-51 Mustang PTS H-9 is acting up (I'm probably the problem). It starts up and dies after 30 seconds. After a few starts no longer wants to start. I can't even go above medium to full throttle.

I have played with the High speed needle. I know some people say to turn 2.5 times but this model seems to only go around once because a device stops it.

Any help is greatly appreciated. Seasons greeting and happy new year.

Best.

The Evolution .46 has two adjustments. Standing at the rear of the plane looking forward the adj. on the left side is the high speed needle. It is horizontal and if you look you will see a small spring steel clip that clicks on the needle adjustment as you turn it. Also, there is a very small pin that stick thru the adjustment pin and protrudes just a tiny
bit. You may have to lift the spring "clicker" to go over this pin. I think you should start about 1 1/2 turns out.

On the right side (looking from the rear of the plane) is the low speed adjustment. On the round blue collor is a small pin that protrudes up about 3/16" out of the blue collar. It is limited in forward/backward travel by
stops. You can only move it forward or backward about 1/4 - 3/8". This is primary low speed adjustment. Pushing it toward the rear of the plane to the "stop" richens the
mixture. Pulling it forward toward the propeller, leans the mixture. Start with it set about halfway between the stops. The pin will be pointing nearly straight up.



Start the engine, leave the Glow Ignitor on and let the engine warm up at a fast idle for a minute or two. Remove the glow ignitor. If it dies or the RPM decreases at a fast idle
it is too rich. Pull the slow idle pin (right side) further back toward the propeller.When you get it where it will idle fairly good advance the throttle slowly, let the RPM's build. Continue to open the throttle until you have it wide open. Open the high speed adjustment (left side) counter-clockwise slowly a little at a time.

What you want to do is slowly open or close the high speed needle until you reach maximum RPM and then richen the mixture (counter-clockwise until you hear the RPM drop about 300 RPM) or about 1/8 to 1/4 turn. AT full RPM when adjusted correctly you will clearly see some exhaust smoke and fine droplets of fuel.

Return to idle, advance the throttle rather quickly. It should not stutter or stumble. If it does, play with the primary low speed adjustment. Move the pin just a little at a time, probably toward the rear of the plane. Advance throttle quickly, let it run at high speed for 5 - 10 seconds and then return to idle, let idle for 5 - 10 seco0nds and return to high speed.

Once you get it taking throttle good, then it's just a matter of very minute adjustments to tweak it. If someone with experience is vailable, get with them and let them show you.

All adjustments should be very small, not more than 1/8 turn (preferably less) at a time.

You said you are on your own? Please look for some local help to get you started with flying. Getting the engine running is only a small part of what is involved. Without hands on help, you can expect to crash your plane repeatedly, untill it is no longer repairable. It is possible to learn to fly "on your own", but it is a very expensive and frustrating process. Good luck to you!

The Evolution engines are "supposed to be factory run in and adjusted". Some that come out of the box indeed run fine with the existing settings. Some won't stay running at all because the low speed valve in some cases is actually completly closed! Please do yourself a favour and contact the local hobby shop and ask them for contact numbers for the nearest flying club. The yearly fees are probably very reasonable. Training in most casess in included in the price of the membership and will pay for itself the first time your club instructor saves your plane from crashing! Just for info the H9 P-51 is more of an advanced trainer and won't last as long as a standard high wing trainer if you go it alone. Not that either one would last over 30 seconds!! [X(]

Make sure the fuel line and the line to the muffler is not switch, it will run but not for very long. I did this once and it took us a long time to realize what the problem was. After that I felt really really stupid!!

Thanks everyone for the great info.

I have been able to get arround the HSNV and was able to increase the speed slightly. The engine did not die but I was not able to reach full throttle and can't still start the engine after a few starts.

I think maybe my glow plug burns out after a while or maybe its the glow starter so I have ordered more plugs and a new starter. i'll keep playing with it and i'll keep you posted. Thanks for all your help.

As for me going it alone. It's not by choice really. I am simulatoring myself to death and fully understand that I will most likely crash it. So be it. I was warned. I will not be discouraged and I'm having fun problem solving.

Thanks again.

Most glow starters are rechargeable or you can change the batt. in some. If your glow starter is good you can take the plug out of the motor and stick it on your glow starter and if it glows orange then it should be good!

Good luck

Do you not have a field near you??

you might be too lean on the engine and it is overheating. This condition will destroy an engine. Seek help from someone who knows what he is doing. It is easier for all of us to fix and engine in person then over a message board becuase we see things differently then someone who is not familiar with the products

Thanks for the advice on the glow. It does seem after a while that the plug doesn;t glow after a few tries when I take it out. However the engine has been idling for a few minutes and I am making improvements.
I took off the cowl now cause there seems to be a large amount of fuel leaking. Upon inspection its comming from the carburator.

As for the air field there is one but it doesn't look like its in service. I am 30 minutes away from it and I've tried to contact them but no dice. I will move forward on my own step by step.

Thanks again guys.
