Totally agree with Jon’s thoughts on spins.

Much better sequence overall. I believe it is more in line with the intent of the sequence guide. It certainly makes the transition from advanced more doable. It also appears to be less power hungry.

One comment. I, and several others, are not fans of end box spins. In heavy crosswinds, like the last NATS, the plane drifts as allowed without penalty FOR THAT MANEUVER, even if it goes out of box. However, unless the proposal to correct this passes the contest board, the following maneuver gets penalized for cross box or out of box before the maneuver actually starts. So the pilot gets a penalty in one maneuver for allowable drift in another. There is no guarantee the proposal will pass.  In this sequence, a three turn spin allows even more drift than we have with 2.5 in the current sequence.

I would argue that the entry and exit of a spin are what really count in judging. Therefore, if end box spins are kept, reducing it to one turn or 1.5 with a 1/2 roll out reduces the drift component considerably. 3 turns is just too many for end box.

I'd also suggest that the top hat have a straight ahead option if the pilot does not need to correct in and out. I often wish the current sequence had the option.

Good effort!

Jon

Lets look at this, we can replace the Double key (K 5) with an avalanche K3 to get the snap in a center maneuver or lets put the maneuver we originally had in advanced, and avalanche with ½ roll in and out (K4), and remove the snap from the next maneuver reverse cuban turnaround.  Also changed a stall turn to ½ rolls reversed going up.

Tony thanks for looking at this with an open mind and critical eye.  To be honest I wasn’t going to initially post this but was convinced to by a group of D 1 flyers at the contest yesterday.  If for no other reason than to show that the committee did consider a more “conventional” sequence in addition to the one that was sent out.

And I did change a few things last night after spending the full day in the sun and I promise only 1 beer at dinner so I may have messed up a thing or 2.

Can this be the basis of the recommended sequence?  As I understand the process the committee sends the proposals to the BOD.  They review and in this case have asked for membership feedback and then make their recommendations to the committee.  If the BOD decides that sequence 1 is too difficult and this one meets the goals of the NSRCA better then they can ask us to tweak this one instead.  Did I send this out at the request of the entire sequence committee?  No I did not.

#4 From top of the box push 3/8 loop to a 45 2 of 4 push back to level inverted flight full roll across the bottom push back 3/8 loop to a 45 degree up line towards top center of the box 2 of 4 and push 3/8 loop back to horizontal (upright)

Can easily make a case to be a K5 😊

#6 correct ½ rolls only I will have to review current maneuvers for the K factor. Pretty late right now but I wanted to provide a response as best I could.

#12 comes from P19 and that is the k factor they gave it so that is what we were using right or wrong we have to start somewhere.  

Double key only reason it is in here is it is in P19 and as I stated I sort of like having a few of the same maneuvers as FAI (not the clown dance)  I need to try to fly it to see if it really a good maneuver or not but it is certainly an easy place to swap to a K4.

Roll reversal:  The knife edge flight you have to roll the other way after knife edge to come out upright.  But one can be put in the stall turns as well or somewhere else if we think another one needs to be included.

Snaps.  You are correct I misplaced one trying to simplify the pattern a little. Maybe after the 1 1/4 roll in the middle of the knife edge flight 😊  

I will look at the sequence and get one back in there.

Stuart, 

#4. The description doesn't seem to make sense. Isn't it an upright entry, PUSH to 45, 2 of 4 roll, PULL to level flight, Full roll from upright to upright, PULL to 45, 2 of 4 roll, push to exit upright? Or am I missing something? Also, it seems to be pushing being a K4. Here are the two closest examples in the Guide.

 Triangular loop (base at bottom) with half rolls in all legs, exit inverted (K4)

 Triangular loop from top (base at bottom) w/ half rolls on 45 degree legs, 2/4-pt roll on

base leg (K5)

It would seem that the maneuver proposed should be a K5. You might want to go with 1/2 rolls on all legs and redo a few things to get the upright/inverted thing going again.

#6. I had to actually draw this one out to visualize it. Just so I'm sure, you enter inverted and at center push to a 30 degree angle? I like the maneuver but I think it's really a K5 not a 4. The Guide has no 6-sided loop on corner, but a standard 6-sided with just a 2 of 4 on top is a K4.

#12. I still feel that a very good case can be made that this maneuver is a K5, not a K4. 

Both snaps are in turnaround maneuvers. You need a center snap. Guide says:  Minimum of two Snap Rolls but no more than three (one may be a turnaround maneuver).  

The only roll reversal is in the 4/8 opposite. You might want to incorporate another in one of the looping maneuvers. Maybe in the Figure Z. Maybe a 3 of 4 with a reverse 3 of 4. Or something less. Maybe just reverse the 2 rolls. But that might bump it to a K5 also.

You have to address the snap issue and in my opinion you have too many K5 maneuvers. Maximum according to the Guide is 4. I think this has to be addressed. I would dump the Double Key and use a K4 from the Guide in it's place as a start.

Otherwise to me it looks like a better pattern to work with then the current proposal.

Is there any chance that what is worked out here might actually make it in as an official proposal?

Thank you, you are correct I swapped the Cuban with a roll to allow better entry to the knife edge roll

To keep the Cuban an inverted entry and exit we can change the spin to 3 turn spin with an inverted exit (may bump the k?)

And change the stall turn to 1/2 roll down only.

Stuart,
I believe the reverse cuban with full rolls should be from upright.
Good luck with this.
