2016 | Stanley Slopefest | 26/27 Nov.

Enjoy two days of fun-flying on some of the best slope-soaring sites in Tas.
Pilots need current MAAA membership and thus insurance coverage. Advisable to book a cabin early.

In an effort to reduce numbers and ensure that the event is manageable, this year the event will be restricted to SEAT full & associate members only. Contact the Pres. for further details.

Flying Sites

Our usual St.Leonards site is now off-limits due to new fencing. Use the Corallin field. The top field is under new ownership and access is yet to be negotiated (Aug. 2014)

For more details regarding access/ location see President S. Boag.

It is with great sadness we report the passing of Mary Bainbridge.

Mrs. Mary Bainbridge 1937-2014.
Mary was our Club Secretary for many years and an avid supporter of this great sport / hobby and loved the club.

A founding member of the club, she will be sorely missed. Famous for her camaraderie and always generous with her sweet teas and chocolate biscuits.

Her life was celebrated at a memorial service held at friend Gill Waddle's home, Evandale.

Tough Conditions
on both days gave the high-class field of 8 pilots a chance to push their launching and thermalling skills to the limit. 12 rounds flown allowed 2 droppers which to some, proved very handy.

Interstate guests Greg Potter, Gary Whitfield and Darrel Blow enjoyed another terrific event at Valleyfield. They all promise to return next year (with their entourage) to indulge in some top-notch Tassie thermalling.

Gliders flown included Greg's trusty Pike Perfect Extreme, John Skinner's FOSA fresh from the F3B Worlds in China (and launching to the moon in the wind) , Gary's Perfect, Darrel's Aspire, Bruce's Cobra, Stephen's Ultra-Orange Supra (flown to great effect in the gusty conditions), Mike Taylor's Perfect and the only Explorer 3.5 from Chris Adams.

Saturday offered a mild, steady 15kt breeze all day and pilots had to make the decision to either stay with the thermal they're in and get taken a mile downwind OR leave it prematurely and stay on the field in the hope another thermal would come along. There were many out-landings.

Re-launches were popular with some rounds only permitting 3mins single flights despite 2 launches. Mostly the air was bouyant but fast-moving. Half-ballast was used by most pilots. Speaking of ballast, lunch was again sourced from the Epping Forest Servo with their quite delicious rolls and sandwiches.

Sunday morning offered great flying conditions until about 10:15am when the predicted Nor' Wester kicked-in. With 12 rounds flown we packed-up with a rain squall visible only 10 mins away.

Warwick Bonney again did a great job as CD ably assisted by Mary Bainbridge.

Kudos to John's girlfriend Lou for taking some excellent photos of the event. Trying to frame these fast-moving gliders is a tough ask but she nailed it several times.

Apres-Fly was held at the beautiful Barton Cottage (not far from the field) where Gary & Darrel had sourced accommodation. This was a terrific informal ceremony and if the weather had been warmer I daresay placegetters would have taken the plunge in the lake nearby.

Congrats to Greg 1st, Stephen 2nd and John 3rd.

Next year promises to be bigger than ever.

SEAT 2010 Tasmanian State Champs

Report: Chris Adams

gary, darrel and florian with trophiesFollowing an amazing 2 days of challenging conditions, 17 rounds flown there could only be one winner; step forward Darrel Blow! Coming all the way from Mildura with his wing man Gary Whitfield, the pair showed how a keen eye for thermals and accurate consistent landings could clinch the points. Credit goes to Florian for campaigning his vac-bagged Magic so effectively against the moldies.

The weather served up perfect thermaling conditions even for nostalgic F3B ships from the 90's. Thanks go to SEAT exec. for running a smooth fuss-free contest, Glen A. for recording flight scores and Gerry Carter for the scoring software that allowed all results to be processed reliably and very quickly.

Only 3 mild bingles all comp. but then that's why they invented glue & fabric.

Valleyfield is proving to be a perfect venue for glider comps and we look forward to running further events there.

Fancy your comp. analysis in 3-D? (thanks John Skinner)

green machine stephen boag holdingSteve's Green Machine continues to impress with its natural speed and energy retention out of downwind turns. Fastest Time of the Day was Stephen's at 61sec. Breaking the minute mark at 7AD is the Holy Grail.

2 Florian Lindner 4879.68
3 Mike Taylor 4648.17
4 Chris Adams 4163.65
5 Bruce Nye 3291.59
6 John Skinner 0.00

Conditions were very good; no rain, mild to fresh temps, wind only just tending Westerley. Buzzer system worked perfectly again (thanks Bruce). Kudos to Glen for buzzing Base B for the day.

Only casualty of the day was John's Shooter attacked by a big eagle. V-tail came off and despite full brakes, landing badly. Almost total write-off. The eagle disaappeared with its mate only to return as soon as a glider went up. Event postponed for 10mins to allow them to depart.

Florian's Magic fly-throughOn a brighter note, Mike's new Crossfire 2 RDS looked the goods with impressive straight-line speed on par with the Machine. Chris had his GoPro HD cam on the Elvis Estrella; seeing the course from above is exhilarating!

Only 6 rounds flown thanks to interruptions, stopping at 3pm when the wind swung completely to the west. Next F3F TBA.


Projects Underway: Nexor Pro

cnc'd mdf plugAfter consultation with fellow pilots and rigorous competition-level flight testing, several new refinements to the Nexor design are planned.

Centre-panel dihedral
It was thought that the hands-off/ nod-off-for-40-winks-stability-while thermalling was lacking so the molds have now been modified to incorporate 3.5 deg. dihedral in the centre panel. All it took was a big circular saw, lots of shimming/ measurement, a new full-length cradle top & bottom and courage.

New Fuselage
carbon/kevalr hybrid sock boomWith a view to making production easier, radio-install easier, ballast insertion/removal easier, reducing AUW by moving servos further towards the nose the Nexor Pro sports a pod/boom design. The mandrel for the boom has been designed and produced the layup for the prototype is kevlar/carbon sock with uni-carbon inner run fore-aft.

Mandrel for joiner box
The joiner boxes will also get the mandrel treatment rather than the semi-effective current method of using the molded joiners as plugs. If a mandrel is used, the boxes can remain straight when they go into the lay-up rather than the awkward method of trying to align 2 separate boxes.

Stanley 2009

Report: Chris Adams Photos: on Flickr Chris Adams/ Max Wiggins

mike, max & florian flyingStanley Slopefest is an annual slope-soaring weekend event held in late Nov./early Dec. at Stanley; a small but beautifully formed fishing/farming village on the remote North-West of Tas.

For those that arrived on the Friday night the weather was bordering on apocalyptical; very angry skies that grew into a full-blown storm. Those that stayed in a Stanley Cosy Cabin reported their huts all swayed like jellies during the night.

After a thorough drenching Stanley served-up perfect West/ Nth-Westerlies. What followed was a wonderful all-day slope soaring opportunity.

Mike Adams's CirrusPeaking at around 20-30 pilots, the sky was filled with foamies/ moldies and the occasional 1/4 scale K13 and 4.5m Multiplex Alpina. The SEAT frequency board proved a godsend and there were surprising few clashes.

Only 2 crashes during the course of the event to report; Chris and Steve may have to get the glue-in.

Pilots came from Sth. Aus (Greg), Melbourne (Marcus), Hobart, Wynyard, Latrobe and Launceston to fly off the magnificent slopes around Stanley.

After flying, our group swooped on the Stanley Hotel Bistro for enough good food to facilitate the customary passing-out-after-flying-all-day-ritual.

Craig and Dynamic 40 in front of The NutSunday was miserable in contrast. Poor weather from 9am with no wind then 2-5kts and mild thermals saw most head off around midday. With only the very lightest foamies, winch launching F3J/B ships and Steve Ralph's ballistic electric wing for entertainment.

Join us next year for some great flying, great views and great Stanley hospitality.

Projects Underway: The Machine

steve at jerilderie holding machineThe Machine is a fully-molded 3D modelled and CNC cut 3m glider.

Stephen's Machine is number 5 in an on-going build series. Each build sees small improvements made to the lay-up, hinging & production process. Weights vary according to lay-up; the lightest yet was Bruce's carbon D-box with an AUW of 1.9Kg

Steve flew his at Jerilderie 2009 as a 3rd back-up model. Further experiments with CG & model set-up including ballast loads will push the design envelope.

For further info see Projects.

Projects Underway: The Nexor

bruce cuts wiper gap with dremelAnother fully-molded 3.4 metre competition glider. This time using cheap MDF as the plug material, with the costs going towards a high-quality but easy to fabricate mould. Bruce's prototype was named "Nexor" as a tribute to it's gliding ability (it stays up so long it makes your neck sore).

The Nexor was maidened at the Milang F3J International in March 2009 and performed on a par with commercial models 4x the price!

servo lead to laptop

The next iteration of the design incorporates dihedral to enhance roll-stability further.

For further info see Projects.

Projects Underway: Taslotto

Continuing the theme of using MDF as the plug material, the "Taslotto" F3B ship is based on HN-483 sections and built in one-piece. The Taslotto uses the same v-tail fuselage as the Nexor.
