Biff old buddy.

As for the final powertain setup I was happy with, here in Southeast Michigan. Reason I mention where we are at is elevations temp and humidity. Approx 700 feet about sea level. Temps in the summer on average around 85 to 90 degrees with humidity to match. Anyway all of the pics are my plane, and I am the builder.

Heres the powertrain setup. Mintor 170, with a Hatori 917 header at the stock length. ES Composite pipe, I will have to look into what part # pipe I used on that plane and get back with you on it. There is a 3/16 inch gap between the header and pipe. I run two O.S. A5 plugs in that engine. Fuel is Cool Power 15%. Prop is an APC 17x13 two bladder for the windy days, and a Dave Lockhart repitched APC 15.75x11 three bladder on the calmer days. The three blade prop takes some getting used to, so if you try one give it a chance before you give up on it. High needle is set out at 1 1/4 turns, and the low end adjustment is right in the middle. I did have to adjust the fuel pressure regulator to get a reliable idle from that engine. If you turn the regulator screw counter clockwise you will lower the fuel pressure. Most likely you will need to do that, otherwise it will be a slobbery pig. If memory serves me corectley, I needed to loosen the regulator screw 3/4's of a turn as a ballpark figure. Don't be afraid to adjust that thing, even though everybody says not to. I have made quite a few of the 170's run real good, and mine has never let me down. You choose a great engine to go with. Plus it's pretty.

If you have any other questions let me know. We will get that thing running good. Ask the Animal about mine, he has flown it many times. He hates to admit that he likes the two stroke, but he loves to fly it.

Guys,

I need to make a correction from one of my earlier posts. When I stated what the engine was in the second Olympian Medal I built, I said it was an O.S. 140RX. That is incorrect as the pictures show. The first Oly had the O.S. in it. The second one has a Mintor 170, as the pics show. Sorry for the confusion.

Hey Mike,
No, I'm not flying FAI. If I tried, it would basically look like crap. LOL I still can't decide if I'm going to get a 2M plane and really get serious with the pattern. The only down side is school, and the field I fly at is an hour away, so its a bit of a drive. Not much time to practice.

Later,
Doug

I think I am going to get back into pattern. now that i think about it, I have nothing else to do except fly the foamy and the heli. The normal flying around and 3D is starting to get boring, and the heli is a heli. I wanted to get inot jets but thinking about it, it would be funner to get a 2M plane than to spend $5,000 on a jet just to go fast in circles. I just have to think of what plane I should get, Probably a Brio or a Focus. Everything else is from Europe or too expensive. I just have to finish my current project which is a Fliton Extra with a Hacker C50 10L. Start saving and I might be able to buy the plane this summer.

You guys have any suggestions on 2M planes for me?

Later,
Doug

Dougy,

School is NEVER the downside. Without an education you don't have anything. Put school first. Toy aiplanes are last. Don't forget about family either, and you know what I mean about that. Hang in there, keep up those grades, you are a smart kid. Like I told you when I first met you. You have a lot of potential. Keep it that way. Without a good education, you won't get a good job, and you won't be able to afford the cool toy planes that you want. Keep it positive. Don't forget the family thing either, and don't forget how how you got started in this wonderful hobby either. You know what I am talking about. Your still my little bud, now get back up here and let's get back to doing what we love to do so much, and that's flying.

Piece, my friend,

I hear ya Mike. I havn't done anything big with the hobby because in three and a half years the palnes will be put away and I will be doing whatever I will be doing. This summer i am trying to get up there for a week so we can get together at the field and have fun.(Me, my dad, you, Ken, Scott, etc...) it looks like I will be able to get up threre. I just have to make sure nobody is going to be gone. Bell is going to ring in a couple of minutes, have to get to French class.

Au Revoir,
Doug

Doug,

Are you going to be flying Sportsman this year? If so, you do not need a full blown 2 meter ship. There are plenty of planes capable of flying Sportsman, and even Intermediate. Ask Scott Pavlock if he will sell you his Summit. I am not sure it he is willing to part with it or not, but he did very well with it. Don't get wrapped up in having to have the best of everything, it just is not necessary. In fact Ken Thompson and I have been playing with a couple of Showtime 4d's and they are very good Pattern/IMAC crossover planes for the lower classes. It is very pattern capable. I have an O.S. 1.60 in mine, and Ken has a Saito 1.50 in his, and both planes have way more power than they need. Sounds like you don't want to spend a whole lot of money on a patten plane right now, and that's good because you don't need to. Maybe you could look for a good used pattern plane. There are plenty of them out there. To many people think they have to have top of the line equipment to compete in pattern. That does not really hold true until you get into FAI and are flying at the top level in that class. Just relax and have fun. Besides if you plant and expensive 2 meter ship you will be out of it for awhile trying to replace it. Then you are out all of that practice time, because you don't have anything to fly. Think about what your pattern plans are, then let me know, and we will talk. Talk with your Dad about this too. He has been practicing pattern a lot, and I must say he is the most improved pilot in RCCD for the year 2005. You really missed a lot being down in Newport News this year. We also missed you at the Nats, and my contest. What happened? We were expecting you at both events. Not to mention you missed one of the best FREE barbeques at my house on Saturday night after my contest. Take some time and think about what you want to do. When you figure it out let me know, and I will get together with you and your Dad, and we will come up with a plan that suits you. Have you considered going to the Youth Masters? I strongly suggest considering that also.

Is that Revolution Pro yours Bob? Why don't you post some pictures of it silly boy, instead of hustling us to do the same.

Hi Guys,
Got to ask a question about the El Nino. It looks awesome. I thought there was more photos when I checked the other day but Anyway?

What is with the rudder, I have never seen a rudder like that on a pattern plane.
Just to clarify that I fly pattern down in Australia, have seen many planes but nothing with a rudder like that!!!!

Is it some special trimming aid, can someone fill me in with its purpose.
We dont get many US designed planes and so this picture has me interested??

Thanks,
Spocky.

The rudder has a boost tab, it was on the plane when I bought it. The boost tab moves a little in the opposite direction of the rudder giving it more authority.

If you would like, I can post more pics of the entire plane, I'll need a day or so.

What you are seeing on the rudder of Ken's El Nino' is called a boost tab. This increases rudder authority. It is rarely used, but is very effective. We used to have a pilot that flew in our district and he had a Piorun Olympian with a boost tab on the rudder. The plane did not have a rudder servo. He had a micro servo built into the rudder, yes the rudder. This mini servos only job was to operate the boost tab on the rudder. When the boost tab is operated the rudder will deflect on it's own in the opisite direction of the boost tabs direction. The Olympian I am talking about was flying in the Masters class in 2002, and did very well. He was one of our top pilots. He has since moved out of our district so I do not know if he is still using boost tabs on his pattern planes or not. Boost tabs are no longer necessary with the servo technology we have today. These guys were experimenting with ways to get the most amount of rudder authority while adding as little weight to the airframe as possible. This is why the rudder boost tabs were used at that time. I do not know of anybody that is currently using a rudder boost tab on a pattern plane other that Ken on his El Nino', and this is because this is a plane that was built by one of our best builders during the rudder authority experimentation process. There is two ways to make a rudder boost tab operate. One is with a servo mounted in the rudder itself that operates the boost tab like I mentioned earlier. The other method is to run a pushrod from the boost tab to the vertical fin. When the rudder servo in the plane operates the rudder the pushrod to the boost tab will force the tab in the oppisite direction of the rudder movement increasing rudder authority. When using a boost tab, you can use a much lower torque servo and have plenty of authority.

Hope this helps,

Mike Darr

Thanks for the explanation guys, you learn something new everyday?

I've never seen or heard about a boost tab unitl now!!!

I keep looking at Temptation's build pictures over and over. This is one of the most detailed and awesome build threads I've seen
