US Team Selection, Time accumulation for 2011

Those of you entering the 2011 FAI program need to be aware of a couple time-tracking issues. The MMM Club received our contest sanctions for the year without form 317 "FAI Free Flight Times Report Form" enclosed. Later, my "Proof of Program Entry" card arrived with an expired version of form 317 with Chuck Markos' name scratched out and the correct name and mailing info stapled to the form. Form 317 on the AMA website was revised last December and has the correct information. Bottom line is that any contest in which you are accumulating flight time for Finals qualification, make sure the CD: A) has the form, B) has the correct mailing info (Chuck Etherington not Chuck Markos), and C) understands that he need to complete the form and mail it so you will get credit for the contest. The link to the form on the AMA website is: http://www.modelaircraft.org/files/317.pdf.

Thanks.

The right Chuck (Etherington)






Q idea from R/C Duration

Roger
Regarding the debate over F1Q rules I wonder if anyone has considered the use of height limiters in the motor circuit. In the UK we are flying electric RC duration events using height limiters. We previously tried a 200 watts/kg limit but this involved a lot of checking on the field and still resulted in big differences in height because the only other restriction was maximum model weight of 2kg. Now we are using height limiters that stop the motor at 200m or 30 seconds whichever is sooner. The result is a much better competition allowing a wide variety of designs to compete on an equal basis. The height limiters are set and checked using a laptop in a few seconds so CDs have an easy job. Also plots of individual flights can be produced and saved on laptop/PC to provide feedback on performance. If height limiters were used for F1Q I think the model/power specifications could be quite flexible. As with RC there would be the choice to put a motor run limit as well as height. In RC competitions the CD has the option to check a limiter at any time if infringement of the limits is suspected.

Height Limiters are supplied by RC Electronics through local dealers. See www.rc-electronics.org. In the UK martin Bell at This email address is being protected from spambots.

In an RC electric glider the height limiter connects between the motorcontroller and the receiver (we are all using brushless motors). Cut off is automatic at the set altitude or time whichever is sooner. The altitude and time are set using a PC or laptop. The height limiter weighs 6.1gm with a cable that could be shortened to save some weight.


I guess for a free flight plane something needs to replace the receiver to set the motor speed through the controller. No doubt those already using brushless motors for F1Q already know how to do this.


The altimeter we are using is RC Altimeter #2 BASIC. The supplier's web site does not make it clear that this is a cut off device, they just call it an altimeter.

Skyscraper International Results


Free Flight Friends,


  Below are the results of the Skyscraper International Challenge, May 30-31, 2009, Americas Cup, Hartill Trophy, and National Cup competition. Dave Acton was CD and single-handedly ran the entry and scorekeepers table.  The scores I provide are copied from his sheets.  If you see any corrections let us know. We had 41 competitors flying FAI,AMA,NFFS events and 15 competitors in FAC events, separately run by Ed Pelatowski.


  We held 10 rounds in F1A,F1B,F1C,F1P.  Saturday morning after the first round the wind shifted to be from the west, forcing flights from a turbulent area. Maxes Saturday were reduced to 150 after the second round. Sunday morning for the four minute max round at 7am, many did not take advantage of early calm at the start of the round and met challenging conditions when the wind picked up. Noteworthy performances in F1B were by Aram Schlosberg and Tom Vacarro with nearly perfect scores and young Brede Dofrner who had perfect scores on all five flights Saturday afternoon. Noteworthy in F1A were junior competitor Timothy B., who finished ahead of Bob Sifleet and Tzvetan Tvetkov, and Michelle B. who had the lead at the end of the first day. In F1C we were very pleased to have had a superlative effort by Andrei Kirilenko with a near max-out.  F1P featured a tight race between junior Brian Pacelli and Skyscraper-of-the-year Dave Rounsaville; with Brian putting in the two days of flying to get the win.


  Rich Ivers and his father Dick Ivers (Sr) took the lead in the electric events with long strings of maxes, with Dick finishing on top after seven maxes in electric B, and five near-maxes in F1Q.


  Sunday saw some calming in the early afternoon. John Clapp and Don

Rousseau took advantage of it in F1G to max four out of five flights, with John getting the win.  Al Volmer won catapult glider both days.  Vic Nippert thermalled for the win in hand launch glider.  Bob Sowder and Gene Pailet battled it out in classic gas events. Bill Buss maxed two of three to win P-30.  Carrol Allen posted top score in Dawn Unlimited. These and additional outcomes are shown below.


  A fly-away noon Sunday by Julie Barron in Classic Towline with her rainbow colored Brilliant (designed and kitted by Denis Phalen) kept some of the Barrons occupied with the chase.  It failed to DT and rose into the clouds heading northeast.  Peter, Julie and I chased its signal by van along Interstate 84 past Middletown, Walden, and Newburgh.  In Newburgh it changed direction now heading east, now two hours into the flight. We twice saw it as it decended to below line height.  We hoped for a landing but it rose again over the Newburgh golf course and headed out over the wide Hudson river near the Newburgh-Beacon Hamilton Fish Bridge. We lost the signal at two and a half hours as it headed past Fishkill over mountains to the east-southeast.  Aerial search the next day over those parts of New York and on into Connecticut was unsuccessful in part due to some unexplained interference precisely at her frequency.  If it managed to fly another three hours it might have made it to the Atlantic.  The flight and search we will long remember.  Our apologies to any we may have inconvenienced by our absence Sunday afternoon in looking after field matters.


  I hope to see many at next weeks Wilber and Orville competition (June 13-14) at our field.  My next email will distribute word of its schedule.


  We certainly do not want to shortchange recognition of the winners and other very good flying in last weeks competiton.  Here are the results of the Skyscraper Challenge.
