Pietenpol-List: progress on Scout

Post by matronics »

Original Posted By: Oscar Zuniga
=0A=0A=0AWell=2C I had an encouraging weekend. Quite busy=2C but still was able to get to the hangar both Saturday and today. Yesterday I got the carb all finished up and reinstalled=2C along with the air box=2C filter=2C fuel line=2C throttle=2C and carb heat control. I had to rig up a little fuel container (Folger's coffee plastic tub) with shutoff valve (beer-making supplies section at your Ace Aircraft Supply)=2C and feed line and elevate it above the level of the carb (which was on the bench). I put a section of clear tubing on a barbed elbow fitting out of the bottom of the float bowl to allow me to see the fuel level relative to the top of the bowl. On the Stromberg=2C the float level is adjusted by changing the thickness of fiber washer that's installed under the brass fitting that includes the needle seat. Adjustment is made in 1/64" increments and my float level was perfect on the third try=2C with a 1/16" washer. In between tries=2C you shut off the fuel and drain everything out=2C take the float assembly apart=2C and change washers. Once everything is set=2C you safety-wire the brass fitting in place and button up the carb. I've gotten where I can disassemble and assemble them with my eyes closed=2C and I would probably get just as many safety wire punctures on my fingers with my eyes open or closed. Everything on a Stromberg gets safetied.Today I tackled the front main seal. Third time's a charm=2C and it just takes patience and a steady hand. I closed the hangar doors=2C turned on the lights=2C cranked up the C&W music on the boombox=2C got myself some coffee=2C lined everything up close at hand=2C and dived in. The trick turned out to be using a small wooden lath between the back of the prop hub and the seal to hold the bottom in place while I pushed the top and sides into place. Once the seal was started into place all around the pocket=2C then it was just a matter of sliding it evenly into place and it was done. The Permaseal Ultra Black has to set 24 hours=2C so I wasn't able to fire up the engine today. I have everything in readiness though=2C so I'm going to sneak out of work sometime this week and go pull it through. The weather is supposed to be beautiful this week and I've just got to hear that engine run again.I'm going to call the A&P to schedule the annual=2C I'll fill in the logs to show everything I've done since moving the airplane up here=2C make sure the W&B is current (I changed the tailwheel and it shifted a little weight off the tail)=2C and then see if I can get back in the air. Four weeks till the Frazier Lake fly-in.Oscar ZunigaMedford=2C ORAir Camper NX41CC "Scout"A75 power =0A ________________________________________________________________________________

Pietenpol-List: mag switches

Post by matronics »

Original Posted By: "Clif Dawson"
Dennis=3BI coughed up the $$ and bought one of the ACS switches back when I rewired the ignition system on Scout (years ago). They were only slightly less than what they are now. You can always just use two simple SPST toggle switches for your ignition=2C one for each mag=2C but then you'd need to make some sort of locking cover to keep the ignition secure. I have seen someone's Piet=2C not sure whose=2C with simple toggle switches like that mounted outside on the top "boot" cowl where they are accessible to the pilot both when in the cockpit and when outside=2C hand propping. Good quality DC rated toggle switches will be under ten bucks apiece.Oscar ZunigaMedford=2C ORAir Camper NX41CC "Scout"A75 power ________________________________________________________________________________

Thanks for the idea, just need to figure out how to wire it all in, fortunately we have an electronics wizard in our local chapter. Hey, in case I forgot to thank you for the corvair college you hosted in San Antonio years ago, I =98d like to say thanks. Wife had gotten a free ticket for accepting being bumped off a previous flight and had some miles that needed to be used up when the college came up. Told her we should see that womens place, Fredericsburg, and do the river walk. She never new what hit her till we were on our way.Dennis

So I got over to the hangar for just a few minutes today and pulled the airplaneout into the sun. Tied down the tail, turned on the fuel, and pulled the enginethrough four blades. Made the mags hot and then propped it off with gusto.It fired on about the 4th arm, which isn't bad considering the carb has justbeen overhauled and fuel had to make its way into all the passageways and ports.Warmed it up and then hesitatingly applied throttle to see if it was goingto gag and cough without pulling carb heat. It did not. Power ran up, randown, and idle is smooth. I shut it down and will play with it some more thisweekend, but it appears to be ready to put the cowling back on and resume taxitesting. If all goes well, I should get some air under the wings on Saturday.Oh, yeah, and a quick check of the new main seal confirmed that it's bone dry,so hopefully no more oil mist after the oil gets good and hot and thin. I'llfind out after I can fly it for at least a few circuits of the field.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Had a nice hangar visit from Mark Baxter this afternoon. Mark is up in Corvallisand is building a GN-1 but was down in southern Oregon visiting a friend sowe discussed differences in the Piet and the Grega and Mark got a pretty goodlook at Scout.I was pretty inspired after the visit and I had just topped off the brake mastersbefore Mark got there, so I tied down the airplane on the ramp and warmed upthe engine real good (started on the third pull). With the oil warm and thecylinders lubed, I ran a cylinder leakdown test (aka, 'compression test') andwas pleased with the results. It was actually the first time I've ever usedmy new differential compression tester so who knows if I did it right or not,but I'm learning. I don't think I have the knack for nudging the prop back andforth to get the rings to seat in evenly, but it was better than my first attempt,when all I heard was 'whoosh!!!' since I didn't have the piston at TDCand a valve was obviously still off its seat. The tests showed about 72/80 onthree cylinders and 78/80 on the fourth.With that all done and no oil whatsoever showing from the new front seal, I replacedthe engine cowlings, walked around the plane again, and declared it fitfor flight testing tomorrow. Strictly in the pattern, and I'm going to hold myselfto three circuits or at maximum, four. Then everything will get the AceMark I eyeball all over to make sure nothing's amiss. Next week promises to bringbright sunshine and temps in the 80s, so I may just have to go flying beforework one day or head to the hangar after lunch to take the airplane up again.Meanwhile, I still need to get the radio and cables out and make sure Towerand Ground can hear me or else I ain't goin' nowhere.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: progress on Scout

I took Scout up today, and everything went well. The engine runs great and pullsstrong, and with a 9kt wind quartering from my left, the airplane was off therunway before I even knew what was happening. We were at pattern altitudebefore I even got 3/4 of the way down the runway. Handling was exactly as expected,everything is looking good. I need to go up on a still morning to seehow it does in cruise, to see if it's all trimmed out properly. No problems expected.Not so great after I got back down after a couple of circuits though. I taxiedback to the fuel pump and filled the tank (I had been flying with about 1/3 tank),and when I tried to start the engine, I flooded it. Couple of attemptsto start would get it to run for a couple of revs and then sputter and die, soI tried all the hot-start and flooded engine tricks I could remember and thesame thing happened each time. Then I used the last trick I could remember, whichwas to just open the throttle all the way and sit in the shade for about15 minutes while things dried out. It worked.So we're flying, but it's obvious that I'm rusty on my tailwheel skills and open-cockpitradio skills, so I'll be busy brushing up on those. Flying the GarminG1000 in a brand-new Skyhawk with Bose ANC headsets did nothing to help myAir Camper flying skills. And Scott, you said to post pics but I don't know whatyou want to see... it's just an Air Camper ;o) Cockpit covers are attachedin this pic.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/scou ... __________

Congratulations for getting back in the air.

Thanks for the starting tips; I've done all of those things in the past. OnceI get into more of a routine of starting the engine both cold and hot, I'm sureI'll get it down pat.One other thing I'll pass along has to do with my handheld. Flying out of a toweredfield, I need to have a radio so I'm flying with an Icom IC-A23. Radiocheck while using the VHF antenna mounted in the aft fuselage behind the pilot'sseat resulted in "aircraft calling ground, your transmission was unreadable",several times. Reverting to the rubber ducky antenna resulted in "loud andclear", so that's how I'm flying it. To save a little weight I should removethe fixed antenna and coax cable behind the seat and just leave the ground planein place for the ELT and its little whip antenna. Your results may vary.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: progress on Scout

Jerry; I know that the antenna lead-in and connection are less than perfect, butthey appeared to be good enough to at least get a signal out when I'm less thana quarter mile from the tower! I could easily shorten the amount of coaxthat I have from the antenna to the BNC bulkhead feedthrough fitting, and of coursejust having that fitting in the line adds signal loss. Then there is theconnection at the base of the antenna... the braid shield was pulled away fromthe inner core farther than it could have been, so there is probably some signalradiating there. In short, it could be better but I'm inclined not to botherwith it right now since the tower reads me "fife by fife" with the rubberducky. For all I know, the fixed antenna has a 3:1 SWR, is connected with thewrong impedance cable, and is going to smoke my IC-A23 ;o)I have never even looked closely to see what the coax is... it may not even beRG-58 and it's sure not RG-400. If I get the bug to make the antenna work rightone of these days, it won't be a big deal to rework the whole thing and I coulddo it in a few hours. The whip itself is a conventional bent-rod 1/4-waveCOM antenna that came off of a Cessna (I believe).--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Tue, 13 May 2014 17:20:43 +1000Subject: Re: Pietenpol-List: Re: progress on Scout

Oscar,Glad to hear the flight went well. Sounds like you have reached the end of thetunnel although you haven't exited it yet. I guess that comes when you finda new caretaker for scout. I'm with you on the antenna issue. As long as youcan get in and out of the field then don't worry anymore about it. The onlything I can offer you and anyone else flying out of a controlled field is to getthe tower's phone number put into your cell phone. There have been many timesI have landed at a local dirt strip to call the tower and tell them to expectme in 10 minutes and will be landing with no radio due to dead batteries.The controllers really appreciate the notice. Enjoy your time flying scout.BTW, Thanks for the pic. It looks great and see you in a few weeks,--------Scott LiefeldFlying N11MS since March 1972Steel TubeC-85-12Wire WheelsBrodhead in 1996Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: progress on Scout

Peter: yes, there is a ground plane. There is a piece of aluminum sheet spanningacross the lower longerons and filling maybe one framing bay. The COM andELT antennae share the ground plane, which is less than ideal, and I've triedto separate them as much as possible but it's a small space. So I know that thearrangement is severely compromised... the ground plane is too small, the COMantenna isn't centered on the ground plane, and there are control cables passingquite close to the antenna (elevator cables, rudder cables, tailwheel steeringcables). So probably "three strikes and I'm out" as far as that setupbeing able to put out a good signal.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
