RE: MoKan Pattern Contest in Kansas City
Here is the GPS coordinates. Also you will see the box reference. Clearly the outer edge of the pond is good reference for the 150 meters. Flying over the tree line in the back means a lot more than 200 meters. Ihncheol and Jimmy. I will be very happy if you could come.

RE: How hot is too hot to fly?
I am sure that is perfectly fine. Don't worry about temperature or issues in that plane and jus fly. Make sure to grease gearbox every 30-40 flights or when gets too moisy. I logged 100's of flights in that plane in 7 years.

RE: F3A Results - SPOILER
nonstoprc, We need to remember that the stab. has strong effect also. I will guess that the stab. probably has stronger effect than the wings due to the lever action when going down. It start to get complicated but a free body diagram probably will help us a lot. I did free body diagrams many years ago in the engineering school. That was not related to airplanes. Probably, someone out the the rcu community could do one with plane flying level and one going straight up and down (with no wind). Then add the wind and drag effedt assuming that pilot wants to get a 10 going down and up hill. Again, this probably will help us to explain what is going on. We also need to add to this analysis the wing airfoil type and what is required to produce lift (and drag) in the particular wing airfoils we use in pattern. What about the effect of the prop and the motor in this free body diagram. In this evaluation we will need to estimate the relative value of all forces acting in the airplane and recognize which forces will really have effect. Well this looks too time consuming and complicated for me. I will prefer to expend this time flying.

RE: Pattern ship winglet.
Doug, I agree. I installed the T-canns in 4 Abbras. The main effect that I noticed is a net reduction of k.E. mixes. Rudder became more effective so less rudder was need it. Of course they are connected. When people ask me what is that? I tell them that I am sponsored by Carnival Cruise. Here a picture.

RE: Proposed 2013/2014 Sequences
What about FAI - F3a pattern? We need to start to include integrated rolling in AMA pattern. It just will take time. I see us copying the cuban 8 with integrated rolls in the near future. I just wish that we do it sooner and not just taking it from FAI.

IMAC intermidate includes 1/4 rolling circle. FAI P includes cuban with integrated roll s on top. It apperas that AMA pattern is getting behind.

RE: Will YS ever go gas/petrol?
I agree 100%. Just add summer conditions at 90-100 oF in very humid day and try to count 1001, 1002, 1003 before doing each 1/4 roll. This is the only way to know if the motor has enough power. That is the real test.

RE: Will YS ever go gas/petrol?
ZDZ 40 didn't have enough power for the Master-AMA schedule. I tried with pipe in the middle of hot humid summer. Probably a good reason why didn't work for F3A. The plane was 5Kg with wood prop. Pattern pilots find out very fast when something new does not really work.

For the ones that w [quote]ORIGINAL: cmoulder [quote]ORIGINAL: nonstoprc It is difficult to beat a setup of $400 for a reasonable f3a motor ($250) and esc ($150$). Battery pack is $100. Assume three packs, you total cost is $700. Or $900 including charger and ac-dc converter. [/quote] Gotta love the outrunners. $0/0hours maintenance after more than 500 flights between 2 Himax 6330-210's. The expensive ones, at $279.[;)] [/quote] For those that would like to get closer to the YS feeling the inrunners is the option. I have been running the Hacker C50 for more than 5 years with zero problems. I never had a single dead stick. Only grease the gear box every 50 flights. It takes me 15 minutes to do this. Also, I can do "Flying Lunches" during the week. Just take 3 batteries charged and going to the field that is 10 minutes from my office. Probably the single reason that explaing my improvement in the last few years. I go back to work and nobody can notice that I have been flying. I hope my boss is not reading this e-mail..... Hey Tuny. Gasoline in Venezuela is practically free.....

RE: Will YS ever go gas/petrol?
Probably a good reason the motocross engines are water cooled now using 4 valves per cylinder. For good reason motocross prefer 4 stroke water cooled engines and two strokes are not as popular. Some years ago (~2003) I saw a 4 stroke gasser in RC scale competition. It was a propotype engine and they had very hard time to get it going. Looks like that engine didn't go anywhere for RC application. Clearly, if YS wants to use gasoline fuel cooling is going to be an issue and water cooled could be the solution but it is not practical in RC application.
