Rafael,  sounds like it is time for a break.  Go grab a cold one and your favorite book.  I too tried working two jobs and it was hard on the family and me.  Of course I did not have the money to spend on planes when I quit the second job.  Now once you get relaxed and feeling good about the family and such, maybe your progress on the plane won't seem so bad.   It takes time.  I know one individual that will spend a year doing a simple built up plane like the Oriental.  I too have some builds hanging that need to be finished, but lost interest in them.   H^^

Well,
Good health and humor to all! It finally is at the stage of touch-ups. Here are the mechanical results:
From many suggestions, I made the ailerons and elevator fully adjustable (slider). Bought a right and left turn rod ends on the elev. pushrod so it acts as a turnbuckle when adjusted. Got left and right turn HD ball links. Brett laminated bellcrank with leadouts attached at BC end. Offset control horns. 2/3 flap-elevator mix. I may change it, but I am used to an elevator response. Did not built it as a take apart. Added 3/4 in. to elevator total span. Shortened flaps. Added a little rudder for insurance. Widened the rib cap strips. Used rib webbing to the tips.

I did not have much time to build as I am busy with two places of employment. Most of the spare time, I spend with my family. I felt running out of patience at many times and walked away. I am not used to the long process of building a masterpiece as many of you do. I do not think I will ever have such craft-manship. The aircrafts created by many of you, are a work of art. So, I built the Stiletto in hopes that I could see if I have what it takes. I do not. The time needed to dedicate to such a feat, is beyond my realm. I know that the next one will be 10X much better, but it takes a while to throw big bucks into a few pieces of balsa wood. I posted the photo so everyone knows that it was built and it is not BS.

Now, I was shocked with the Brodack's Aviastar 61. I could not resist the Stiletto sitting and waiting for the final clear coat. I blew it away and started the engine. It had the typical burbs when a new engine is started for the first time. Would not kick in for any extended run. I used my started for a few seconds ( NOT like the R/C guys...) at a time and it came alive with a thunder! It was very rich so the needle was tweak a little. No change. The needle for the Aviastar 61 has a very fine thread. One can really dial in the mixture! What a change from those Foxes Combat Specials...

A few tweaks and it ran consistently. The plug was disconnected from the battery and it still was active. Pointed the nose up on its right side and immediately went on a strong two!!! WOW!
Lowered to level on its side and the engine went to a rich 4 and it quit. I experienced the same several times while adjusting the needle. Finally, It would go lean on the up nose, that was that. I was using  my KB-1L that I use for 95% of my engines. I changed to a OS 4-CY that I use for the 4 cycles. It went lean on the up. I FORGOT TO CHANGE THE SETTING BACK. HB~>

I topped the fuel and started the engine. AMAZING!!! #^ y1.
The engine would go to a nice 4 c when level and as soon as i pointed the Stiletto to a 45, it would go to a strong 2C-sputtering 4C stroke. I WAS IN AWE.  Never had an engine do that. Maybe the more expensive have that capability. I do not know how it will behave in flight, but I am ecstatic.

Will report back this weekend when it has its maiden flight...
I apologize for not giving the Stiletto its proper looks. I did some paneling but I lost the patience. It has big wheels because we fly off of a tall grass soccer field . the hole on the side is the flap adjustment and it is covered with a removable round tack used on car rugs, etc.

Prop is 13-5... That is another reason for the big wheels. What would be a good 3 bladed so I can gain more clearance? The Stiletto came in at a whooping 66 oz... HB~> HB~>

Rafael,  that plane is gorgeous from what I see in the pictures.   A lot more work than I do on planes.  I like the report on the 61 engine also.   Hope it flies as well as it looks.  By the way I have a friend that spends a year or more on building his stunt planes.   H^^

Hi Rafael,

That looks super nice!  Nothing there to be apologizing for.  I hope the first flights went well!  Just take your time and get into trimming and you should be very pleased.

Thank you guys. It makes me feel very humbled after seeing some of the very best aircraft presented here. The next one I will try to do it in silk or the PolySpan covering. It has been a long time since I used the stuff (dope, Ambroid (extinct), etc.) One can only imagine the memories that the smell of Sigment and nitrate brought to my mind. Old friends, my father, my uncle, etc. There is one thing that C/L has that no other of the modeling hobbies bring to the table: camaraderie and good friends. When one flies R/C, we are by ourselves. Sure, there are people there to help if you ask, but it is not as necessary or as forth coming as in a C/L circle. By virtue of the sport, we are dwindling in numbers, overcomed by modern technologies. I am very sorry that I was not able to make the Brodack's or the Nats to see the models and pilots. I can hack the PA pattern now, except for the outside squares and the square 8's. My knees knock together everytime I think about trying it. Amost always loose the rudder!  Funny, I have no problems bouncing around in a combat plane... I think it has to do with the investment. I am building a couple of scratch profiles (Magician, and something else) to practice.

Did not get to fly the Stiletto as I was working all weekend HB~> HB~> HB~> HB~>. Maybe THU... Very hot aand windy here.

Will update. H^^

Flew the Stiletto 660 with the Avistar 60. Not good.  HB~> HB~> See the post on the engine set up tips thread. Did some up and down legs(reverse wing overs) engine would transition nice b/t 4 and 2 but would shake/vibrate the lines on the up side for about 5-10 ft. Prop balanced but it may be too much (13-5 zinger). Is that typical of a stunt ship? Level flight and inverted smooth and same controls. At full elevator plane turns ~6ft radius but loss of speed is apparent. No stall. I know too heavy... Have installed the Evo that I won here. It is a shoe in! Just shorter nose (~1/8 to 3/16) did not measure, just added a washer behind the spinner temporarily.

Will try and fly this week with the new engine. Most of my props are for sport, R/C 3D or combat. Will go to the LHS and try an APC 12-5, Zinger 12-5 and an APC 13-5.

Any other suggestions? I am also considering a 3 bladed to give me more clearance... What? ???

Will get back.... H^^ H^^

First off, Ambroid is still available. Second I think most Zinger props are 1. baseball bats 2. prop kits. One of our club members had sanded and scrapped his down thin with undercamber and it works quite nicely.
The APC props might be better than the Zingers.  13x5.

Got mine almost finished, needs black to b e touched up and red/gold stripes added to the stab. H^^

 LL~ LL~ LL~
Right about the Zingers. They are a prop kit. The leading edges are in some props square! But, it is very difficult to find a 13x5. Most LHS cater to the R/C family and carry very few for C/L. The 10x 6s, etc. are plentyfull. I spend about 30-60 min. shaping the top and thinning the tips. Then I use the prop gage... HB~> HB~> They are not cheap either...

Great looking birds.  The Stiletto has always been one of my favorite designs.  I love the way you guys stayed real close to the original paint schemes.

Zinger props remind me of Fox Stunts,  They work great in certain situations.   I one plane that finally woke up when a Zinger 11-5 was put on the LA Blue .40 I was using.  I also like the Master Airscrew wood props also.   Have just gotten some Zoar props to play with.  Anyway I know you will find the right combination for the Stiletto.

Hi Rafael. Well I have finished my 660 and it came out right at 60.3 oz.  Ouch. A a tad heavy, but I feel the ST .51 will carry it. It has a top Flite 12x5 prop.  I will not be able to test fly it until after the 12th of Sept.  Going to Colorado, then to Memphis. Maybe it will lose another ounce while gassing.  Yeah, right, I wish.  D>K H^^ LL~

I know. I can't imagine how they come up so light on others. I put the Evo 60 that I won here on it. The AVISTAR blew up on a vertical down line and almost lost the plane. It would have been catastrophic if it was on the upside. This was the second AVISTAR from Brodacks. The first one I sent back with a written letter explaining the procedure and my experience. See my AVISTAR comments way back a few months on the thread( Engine tunning) Got another and bench run it as required by the instructions. It was flying fine for 4 flights (2-4, etc.). On the 2nd inside square it made that peculiar sound that puts a knot on your stomach. I lost many a crankshaft on the old FOXcombat specials until I replaced them with the more beefier cranks. JUST LIKE THAT THE AVIASTAR SOUNDED! HB~> HB~>
I took it home (Stiletto 660 safe and sound, managed to have enough to pull it out by going back and whipping)and took it apart. I knew what it was without taking it apart. The rod disintegrated!
I have some photos if anyone is interested. The AVIASTAR engine has a rod that is bushed but there is minimal material to hold the bottom end from braking away. It is a heavy piston and needs a heavier bottom on the rod. If this was a speed engine or super RPM I could understand. But this is a low rpm engine. Had an APC 12x5 turning 9730. So it was well within their range. In no way is this a reflection on Brodack's quality on kits and customer service as it was above excellent. But, I am gathering the photos and send them as soon as I find the time. I will never replace any parts on this engine as I will never install it on anything! If I buy the parts, the will be the same and might be tempted to put it on an aircraft.
In essence, the engine was the same as the first one:
Too tight a fit at the piston and the rod started clunking. I did not open the engine and I kept running it as some in here were suggesting not to tinker with the engine. BULL! I know my limits and a stunt or combat engine do not exceed it. Perhaps the speed, team racers are another story. Will report on the EVO. H^^ D>K

Well, my apologies for the late report on the Evo/Stiletto combo. All I can say is that if I had more to invest, I would purchase another Stiletto 660 and another Evo. I won the Evo here. The Stiletto 660 is from Walter. After much tinkering with the Evo, I see that I could have saved a lot of time by log-in back in here sooner! HB~> HB~>

Having a very cloudy idea about PA flying, I requested a good friend (Dick Carville) to fly the Stiletto and let me know what it needed. He was very pleased with the flying. I guess I did a decent job. The timing for inverted and upright is the same. He liked the sharp in and out squares, felt a little sensitive. I told him I had 2-3 ratio Flap/elev. He suggested to go 1/1 at 45. I may but I believe with my style of flying I may keep that for a while (better to have a little more that not enough)

I had the flame-outs that are discussed in here. The flying was done at a temp of 55-60F. The same used to happen when I used to fly combat with friends in the snow... (remember I am in beautiful N.E.)It was fun to slip/fall and try to keep the thing up without the engine eating snow... LL~ LL~ The Foxes would flame out with the cold.

The solution used to be to run a Fox R/C long. It worked for the Evo. It tended to speed up a little bit with an APC 12-5 on 69", handle to engine. Dick brought a baseball bat to slow it down. Less efficient than an APC, the Zinger 13-5 slowed it down to 5.3-5.4. The engine sounded beautiful! This is the winner!! Dick flew it a couple of more times. He wanted to keep flying ( I was getting cold...) and we added muffler pressure to the tank. Now it was on a beautiful 4-2. Did not get an RPM reading as we were still not there yet according to my friend. It was turn for me to fly again with all the trims. At the first flip, the engine backfired, dropped the prop and spinner and started screaming with white smoke everywhere!!! HB~> HB~>

The prop blade hit the engine cowling and split my beautiful nose HB~> HB~> I knew that perhaps that was the last run...Put everything together, took the muffler off and looked inside the exhaust... Nothing! no burns or scratches, no metal runs!!! What an engine! Nice conn. rod and components. The advantages of Castor!!! S?P The Aviastar self-destructed under normal operation!!! We flew several more times taking turns. The tank is 7.5 oz. but the Stiletto runs short.
I may build a tank that will hold a little more or go to less nitro (5-10%)...
Now, I know that a 13-5 is the prop for the Evo. I am wondering about C.F 2 03 3 blades. Too expensive to experiment. Any suggestions?

Merry Xmas to all. Happy Hanukkah

Not knowing your skill level,  one you have a prop that works don't worry about going to carbon props.   Glad to hear the setup is working.   Just don't push it until the real flying weather gets here.   I too used to go out when the temps were low.   Now I shudder then the thermometer shows a high of 50F.
