I was flying my old Napier last night and 2 out of the 4 flights I had an issue with the engine surging and almost quitting after a hard turn... I had a decent amount of smoke and the engine tached at about 23 - 23.4K on the ground with the black prop(V3).. I thought maybe I had some air in the tank so on the 4th flight I took extra care in fueling, set the needle at about 23.2K pinched once, sounded good on the ground but still surged and caughed and sputtered after a hard turn... Any thoughts??

Other than that it was a blast and I can say I've officially be bit by the Q40 bug... Thanks Pat G. for the donatation of the old Napier to get me going and Cole T. for the good deal on the engine.

Sounds like a tank / air / fuel line problem to me. I'd replace it and the fuel line, put in a new glow plug, and try some new fuel.

also check if the plung in the tank is good and tight without a leak...ive had that happen before, even had one come all the way out and ended up messin up the paint on my Neme-Q fuse..somthin to check up on...now where r the pics of ur new plane?

The fuel is a brand new gallon of Powermaster so I don't think it's that. The tank is new as are the lines but I will check those out and see how they look... I checked the plug after my 3rd run and it looked pretty good....

Try a new plug anyways, and put that one aside. Sometimes a plug will look good, and light nice, but the engine still won't run right. Wouldn't hurt to try, easy check.

I'll try that... I got all those plugs from Del, I might as well put them to use

Maybe I'll have to bring it up some weekend and let the experts have a shot at it.

Any and all suggestions are greatly appreciated. I'm new to the Q40 thing so it's all good info...

Here's another couple things to check. Check for a pinched fuel or pressure line. Also, are you running a filter? If so, check it for junk. The only time I ever seem to get debris in my filter is within the first dozen or so runs on a new tank. If your not running a filter, remove the needle and flush it out...

Hey Lee,

Are you thinking of hitting grassfield this weekend ?

I'd like to but I'm forced to head up north(Bemidji) for a family reunion... It will be a good time but with gas being $3/gallon over here I don't know that I want to go.

I was in Bemidji this last weekend doing a swim team trip for my kid.... it's about 260+ miles there from my home.


We'll do a Q40 weekend before the snow flys

This Sat Jesse, Elert, Pat, and I will be there with Q40's.

oh yeah, I'll be there.

haven't had a chance to break in my prize yet, but my Dago seems happy with my Randy Smith special.

I'll see ya' then

Sounds like fun but I haven't been up there in a while so I should probably go...

Weren't you there on Saturday?

If every other thing they have told you is OK. (Air in the tank, plug etc) check if your back plate is OK, the same happens to me 2 weeks ago on a Q500 and the back plate was loose.

Regards-

Thanks Oddy, I'll check that too... I'm just putting a laundry list together of things to check and will probably do it tomorrow and then fly this weekend since I bailed on my family reunion...

oh oh .. Lee's coming out ? someone's going to be in the dog house..

now that is dedication man...bailing on a family reunion to practice...awesome

Actually Jesse, Deann was all for it... No dog house for this boy.. Well, not from that anyway.

Nope, just 2 brothers, and your too late they're both married Talk about a thread that has gone off course
