New South Wales Pattern Flyers

Just an average group of flyers with an obsession for precision aerobatics.

The Arbalest Evolution Has Flown

After 276 hours of build time the Arbalest Evolution has flown. A somewhat shaky start. So far, in 18 flights, I have broken an undercarriage and hit the electric fence at the Nowra comp. New wings are currently under construction.

I am very happy with the way the model was flying. The wings needed a bit more dihedral to remove the 6% rudder to aileron mix required to correct adverse roll. Hopefully the new wings will sort this out. There is a slight pitch up on left rudder but still trimming so looking pretty good. The finished weight was 4260 grams with an 1185 gram Dualsky battery which is very light compared to the old Arbalest. This gives more power in the uplines and a slower downline speed. Seems to spin well (possibly a little better than the Arbalest) and snaps about the same.

The old Arbalest is flying at 4700 grams with the small canopy mounted cannaliser and the lower cannaliser (bellyiser!).

The main contributors to the 440 gram weight reduction for the Arbalest Evolution were:


Saved 69 grams from a light heat sink on the Spin 99 (29 grams) and my own built short undercarriage (22 grams).

Built up items

Wings 48 grams from Solarfilm instead of Monocote (23 grams) and lighter foam/ balsa (25 grams).

Stab 15 grams similar reason to wings.

Rudder 6 grams similar reason to wings.

No bellyiser fitted (83 grams) (Not yet but who knows!).

Canopy with small cannaliser (25 grams).

The majority of the savings came from the fuse and mounts. The fuse moulding contributed only 17 grams and the rest was an accumulation of savings in U/C mounts, wing tube mounts, servo mounts, ESC cooling air ducts, receiver mounts, battery mount, battery tray and paint. Where possible, Nomex honey comb and carbon cloth was used for trays, formers and bracing.

Hope to have the new wings sorted in time for the Masters.

Directions to RAAFMAC

The flying field is located next to the RAAF Ricmond Air force Base and Richmond Airport. Travelling West along Windsor Rd (from Windsor) turn right at Percival St (just before the airport runway). Travel approximately 1km along Percival Street and RAAF MAC can be found down in the grasslands on the right. Please see maps below for further details.

 Directions to Gloucester Aero Club

Gloucester Aero Club is located at 32° 03.1’ S; 151° 58.5’ E. Note that GPS should be set to degrees, minutes and decimal minutes.

From Taree / Wingham / Nabiac via Bucketts Way, before reaching Gloucester, pass Mograni Lookout, Mograni Creek Road and Mograni Creek itself (all clearly signposted) and take the next left into Waukivory Road (aka Avon Valley Way). After 3km this ends at a T junction, and as you approach this you can see the Aero Club a kilometer or so straight ahead. Turn right into Jacks Road over the bridge and after 800m at a crossroads turn left into Maslens Lane, then follow the common route below.

From Tamworth / Armidale via Thunderbolts Way and Barrington: before entering Gloucester turn right at the Bowling Club just before the 50kph limit (signposted Newcastle), after a dog-leg left turn right onto Bucketts Way South, go past the Golf Club where the speed limit changes to 80kph and take the next left into Jacks Road, after 1.7km turn right at a crossroads into Maslens Lane, then follow the common route below.

From Sydney / Newcastle via Bucketts Way South through Stroud and Stratford: when you reach the 80kph limit approaching Gloucester go past Fairbairns Road, travel another couple of kms and take the next right into Jacks Road, after 1.7km turn right into Maslens Lane, then follow common route below.

Common Route: Maslens Lane is a good dirt road leading to the flying club, bending left at the farmhouses. It's in the middle of a dairy farm, so if there are any electric tapes strung across the road take them down, drive over them and reattach behind you. The last 200m can be slippery if it's wet, but it's wide and flat so stay in the middle and take it easy.

Cows may block the road at milking times – typically before 9am and between 3 and 5pm.

The runway is North-South so the sun is a problem in the mornings, but there are no obstructions of any sort to worry an R/Cs model, the view is fantastic all round, and the Clubhouse has TV, hot water, kitchen, toilets and even showers! Camping is available at $15 per night.

The Local Visitors Information Centre has details of accommodation, etc on 02 6558 1406.
