Contact for Bob Krug - Powermaster fuel?

[RknRusty]

Anyone know an e-mail address or phone number for Bob Krug? I want to ask him if he plans to be in Huntersville for the contest May 1st, 2nd and 3rd with Powermaster fuel.

I bought Powermaster 10/22 from him in October thinking it would last through May. It didn't.
The Sig 10/20 I bought didn't agree with my fp40 at all today. It overheated and sagged as soon as the plane lifted off and finally died with nearly a half tank remaining, hot as hell. I put some of the last of my PM 10/22 and it ran great. Glad I didn't kill it. It's an ABN engine which might have saved it.

If anyone knows, please contact me. I know some others who want to know too.
Thanks
Rusty

The Krug-erator is winding down his fuel deal, I am led to believe....
Mike Ostella, a member here, is a liaison for Bob, who is electronically challenged.

  Just add about 4 ounces of castor or synthetic oil to your existing fuel and be happy. There are websites out there that can tell you the exact amount if you want to get picky. SIG sells both castor and Klotz synthetic. Probably several threads on the forum on spiking oil content in fuel also.
  Type at you later,

Okay, thanks for the info, Rich.
Dan, I have castor oil on my shopping list. That fp40 must be finicky, my smaller fp 35 and 25 don't miss a beat when I switch between the two brands.

That seems weird, I have switched back and forth all the time between SiG and Powermaster in my OS and DS engines and had nary a problem.

[RknRusty]

Maybe it inhaled some weed seed while it was rolling out for takeoff or had some other clog that I inadvertently cleared. I opened it up to check the plumbing and backwashed the filter onto a paper towel. It all seemed fine, so I buttoned it up and switched fuel. Hard to tell. No matter, I'll add castor to the Sig and try it again. But after a run on Powermaster.

   Agreed, something seems a little funny with this. My engines run OK on SIG compared to Powermaster, aside from the tater issues. You do have to move the needle a fair bit.

I'll experiment next time out. If any more weirdness happens, I'll start a new thread in the engine forum. As I noted above, my other smaller FP engines didn't miss a beat switching between the two brands.

Even a spec of dirt in the needle will cause issues. Hard to diagnose at a distance. Powermaster has settled down many an engine. New stuff is clear again, no dye. Check muffler and pressure tap. They will clog after a time. Tank. Minute hole in tubing, possible. Common with the blue stuff. 

[RknRusty]

Hi Dennis. When I opened up the cowl and tank cover to check the plumbing, I looked for a leaky pressure line as well as the other lines, but all seemed okay. I'll give it another once over in the shop before I hit the field again Tuesday. Might as well replace all of the lines and pressure check the tank too. But it was perfectly on song after I closed it back up at the field and filled it with Powermaster. When I cranked it with the Sig, I had to richen the mixture to get it down to my launch RPMs, about 11.5k. Still a little leaner than my next powermaster launch, a nice run at 11.1k. I prefer to use my ear, but since I'm still getting used to this setup I decided to tach it.

Since it sagged during the rollout is the reason I first suspected weed seeds. If you could see the short seedy little sprouts at the field, you'd understand what I'm referring to. I have my pitman hold it off the ground until I have my lanyard strapped on and am ready to fly. The Oriental's LG is pretty short too, no doubt mowing the grass as it rolls. I hope it's that simple.

Powermaster has calmed down many an engine. We use it almost exclusively. Richen the mixture another click or two more when you try the Sig. That might help if the engine sags. At one time Powermaster could be ordered direct from the factory. They had a way of getting around hazmet. I'll ask Joe Adamusko. At on time he did that. Powermaster was a family owned company until the last few years. It was taken over the chemical company that had supplied the ingredients for the mix. At least that is the story I heard. Recent batches of Powermaster have worked as well as the original. If you have a hobby shop around, you might be able to get them to order some of the fuel through them. I'll see Bob sooner or later. We bought a lot of fuel from him. Many of us have enough fuel for the coming season. Could be his fairly close by East Cost customers aren't buying like we did. But we will. Eventually.

Sagging sounds like a fuel issue to me. Engine is becoming overheated. But, like I said, very hard to diagnose at a distance.

Yes it was scorching hot. The aluminum spinner backplate was too hot to touch.

Thanks for all the replies, I'll let y'all know whatever I figure out. This is the kind of thing that makes the week before a contest more interesting that I'd ever hope for.

Well, at least if its still acting up we can fix it at the contest!

Anyone can have trouble now and then.  At the contest you can ask Banjock about the 18 minute PA incineration flight I had last Huntersville on Saturday evening.  And yet with Dale and Derek's help we got it back together in time to fly the next morning.

[Dennis Moritz]

Message Mike Ostella, he's in touch with Bob. He could give you a read. Powermaster will ship six gallon cases ground. This avoids hazmet far as I can tell. Shipping charge reasonable. They don't list CL fuel, 22%(50/50 oil) 5% or 10% nitro. But should be available. Bob would be encouraged to bring fuel to home contests, if he knows there will be a quantity buy. He has come to our Philly Flyers field and delivered fuel. Very reasonable cost. This a turnpike trip (tolls) of over 100 miles.

[Dennis Moritz]

I saw that flight! Steve came back and almost beat Dan the next day. Gratitude.

Rusty, just for giggles I would blow some compressed air through the needle spraybar assembly, amazing what harm a little crud can do!

[RknRusty]

Yeah, I'm looking forward to seeing all you guys. Well I know at least Ray and Steve probably will be there. I'll rip her apart, blast out the NV and a good checkup. I'll bring whatever fuel I've got. I'm going to spike the Sig with some drugstore castor and see what happens. It always worked on my other FPs just fine.
Enough already, I've drawn enough attention to myself on this.
Thanks, see you dudes in the funny pages,
Rusty
