I don't know how many people have completed the build yet, but I am VERY pleased with mine so far. I wanted to get some more flights in this past weekend, but the winds were gusting over 20.... no flying for me.

Its absolutely calm and beautiful today, the plane is in the back of my SUV, but I'm stuck in the office ... AAARRGGHGHHHH

Just got my A/C ordered today. I believe that I have identified all but one of the necessary components to complete the a/c when it arrives. What I have not been able to identify is the length of the rudder servo control horn. Since the instructions say to not cross the rudder cables I assume that a straight double horn is used? What length/size works best for the given rudder geometry?

I assume you're talking about the rudder servo arm, not the rudder control horn. I used a 3" arm from SWB. There is a short 45 degree angle on the tips of the arms, but the overall width is 3 inches. With that, had to limit travel to keep the rudder from hitting the elevators at full deflection.

While examining all tail components before gluing, I found this elevator hinge. No sign of the pin being mechanically peened!! I will go with Robart instead. Everyone check your hinges carefully. Can't just be my plane. I know I do not posess superhuman powers of observation. Also a good thing they use about 100 hinges, "redundancy".

For the rudder i am using the factory arm from a 5985 servo still had to reduce the end points to keep it from hitting the fuse its about 2 7/8 inches endpoints are about 90 %

Shundley: I would keep adjusting it mechanically until you can get the desired throw at around 120% on the end points... this will give you your best resolution throughout the range... farther out on the control horn, and closer in on the control arm will reduce mechanical throw...

I was gung ho about getting this pitts. Everything I have been reading has been that it is precise. At the field, others have informed me that a Edge would be much more precise for imac.

Is this true?

Some pilots can make a brick fly like a dream. If you get the Pitts and practice with it you will be sure to please the crowd and judges. At the TOC, biplanes got extra pionts because of the extra drag and Chip Hyde took full advantage of it. I saw the TOC in peson once in the late 90's after it went to an every other year event. I saw many of the big name pilots and their sweet planes. Also saw a relatively new company trying to convince people that a light weight stick built fuse ARC airplane (Edge if I remember correctly)was the way to go. That company was AEROWORKS!!!! Years before that, Godfrey 70" Ultimates, Reed Falcons, Laser 200's and other 30% scale planes that were relatively small compared to todays beasts ruled the TOC.

Put very well I fly 35% extra 35% yak 35% staudacher also have many 30% and 28% planes also I bought a aeroworks yak all planes of any quality will outperform the skill of the pilots some planes just take a little longer to master learn to trim your plane for the imac everybody can imac a extra take the time to learn the pitts soon you will be the dog to beat

I took the Python to the field for its second day of flights today.. only 2 flights. It was very overcast, showers coming in, but for February, it was very calm. I had the vess 23A on it today. Noticably slower than the 23x8 NX, but it did seem to hover and pull out better than the 23x8. I had moved the CG back about 1/2 inch from the recommended setting, this helped a ton.

I think I may need to cut some additional airflow into the engine. It dead sticked on the second flight, and the motor seemed pretty hot when I checked it. No damage at all to the plane, I was suprized how smoothly it floated in with no power. It died pulling out of a turn about 100 feet off the ground... I thought it was going to be toast. It did land in in rough grass, but very smoothly.

Did I mention.. I LOVE this plane on high rates!

How much of the radial dummy engine did you cut out for the cyl? How much of an exit hole did you cut out. I want to make the exit hole plenty large when I cut. I know the nice chin scoop will be gone plus a large area to boot!. I am going to continue with my build tomorrow. Hinging the elevators using three large Robarts and two small ones between to fill the other factory holes. My D/A only has about 1/2 gallon of Lawnboy 40:1 through it so far. I don't want it running hot in the cowl.

(Fast forward to the next day) I am done rigging the tail feathers, servos and all including rudder pull/pull. Went in farthest out hole on the rudder horn (2 3/8" and the 2" spacing on the straight part of the SWB angled arm. Plenty of throw on high at 125% ATV. Using an 8711 monster on the rudder and 8611a's on everything else except the throttle and choke. Using digital Hitech mini servos on them. Using the 9303 for the first time and really starting to like it. Dual servo option on all primary control surfaces and easy to select and de-select. Highly reccommended by me . On the rudder pull/pull I went with some coated kevlar and eyelets that I had on hand. Reason being, when I went to lock a jam nut on the brass ends that were included, the threads started to slide out of the ball clevis. I couldn't pull them out by hand but before the jam nut would lock tight it would begin pulling the brass end out. The eyelets I used have deeper and sharper (also harder) threads and cut in to the clevis better IMHO. Just don't want to be worrying about any more on the maiden than I need to. Some pics.

Whether you want to or not, you'll have to cut out a pretty big section on the bottom of the cowl to be able to get the cowl over the muffler tubes, then get the front of it over the prop shaft. Its all good, though.. like you mentioned, the airflow is good, and it doesn't show.

As for the radial engine dummy, I cut out one "slice", just as displayed in the instructions.

Update on the "dead stick"...

I didn't even look at the motor.. I was mad about the dead stick (third on this motor over about 2 years) and took the soft landing as a gift from above... I put an ad on this website and sold the engine in less than a day... engine, muffler, standoffs, 2 props.. all for $500.

Then, I was taking the motor off the plane to ship it and found the problem (feeling pretty stupid at the moment).. I didn't secure the fuel tube to the motor box properly, and it allowed the tube to come in contact with the hot muffler. It completely melted through the fuel line, choking off the engine.

Anyway, to make a long story short, some guy in Phoenix is getting a great motor for a great price, and I'll be upgrading to a 3W 55CS as soon as Cactus Aviation gets them in. They are supposed to have about 20% more horsepower than the DA-50, so it should really make a difference. Not that the DA wasn't a good motor for the plane.

Anyway, even after a near-death experience followed up by a near-stupid reaction, I still love this plane... can't wait to get it in the air again.

By the way... I had mentioned earlier that I was going to try the Vess 23A prop. I used it for a couple of flights, including the last one.. all in all, I think I liked the NX 23x8 better. The 23A did get the plane up faster, and it would probably help it pull out of a hover, but there was a noticable drop in overall speed. I expected to give up some, but it was more than I expected. Stay with a 23x8.
