Parkzone SE5A

This aircraft was intended as a replacement for the GWS tiger moth. It didn't quite meet my expectations of a floaty WW1 biplane. It's a bit on the faster side. On the plus side, it does handle the wind well. It took some testors paint pens, sharpie markers, toothpicks, pencil crayons and various bits of elastic string to make it more endearing. It now has a spot in my hangar. I do like the challenge of managing the rudder and elevator on landings and take offs.

Time to immortalize it while it still looks good:...Continue Reading

Guanli / Nitroplanes PBY Catalina – brushless ARTF version. Wingspan: 54” Weight: 30.64 oz. (after lightening modifications) Wing area: 2.72 sq feet. Wing Loading: 11.26 oz/sq foot.

Modifications: See pictures for details: 1) Added 1/32 balsa shim at L side of horizontal stabilizer support. This lined up the stabilizer with the wing. 2) Enlarged motor stick mounting holes and added spacers. This enabled exact alignment of both motor support sticks. 3) Moving the battery slightly forward resolved the tail droop seen on the ezone review video 4) Attachment of tip floats with canopy glue and adding a reinforcing bead of glue around the joint has prevented them from failing during > than 100 water landings, many of them “less than ideal.” 5) 0.5 oz fibreglass and WBPU to the hull bottom added only 3 grams! Thanks to Flyboy1001e for the help there. This was applied after a submerged UFO (Unknown Floating Object) punched a small hole in the hull. 6) Canopy glue forced into the rear window blister/fuselage joints with a thin CA applicator tip went a long way toward waterproofing. The fuselage seam was sealed with white glue and spackle. 7) Differential thrust mixing allowed omission of the heavy water rudder. That and omitting the plastic wing joint cover as well as some soldering eliminated another 57 grams. 8) Balancing the props and taking the heavy spinners off was essential after one of the motors vibrated loose on flight #20. 9) Ironed on white econocote covers up...Continue Reading

Apprentice 15e: Floats by SEAPLANE SUPPLY. Almost Stock: Just couldn't resist bringing the floats closer together for a more scale appearance. It now tips over in strong winds but looks a lot better. Flies beautifully. Depron float struts, water rudders as per estarter (see hangar II), and replacing the stickers with custom detailing are on the wish list.

Status: Speed control burnout after prop strike on water - being replaced.

Status May 2010: New turnigy plush 40 amp speed control. Flight time = 40 minutes on 3000mA 3s battery. (Too long to count on the 5000mA battery) Rides the thermals, even with the floats on.

GWS Estarter: Dual water rudders linked into fuselage rudder servo with fishing line in a semi scale format: Adds only a few grams but works beautifully. Pull-pull rudder. Concealed elevator pushrod. Concealed rubber band wing mounting through fuselage. Slows down beautifully with flaps and spoileron function. During ROW, it gets squirrely when up on step but stable when elevator is used to keep float angle high.

Status: Hangar queen: stock motor burned out and crashed into pole. Float angles need to be decreased relative to wing to account for the lack of angle at the step. There is too much of the float in the water ahead of the step.

Too pretty to redo all the gear. Moved on to apprentice to experiment with float angles. Lesson learned: Flight tests first, detailing later!...Continue Reading

GWS Tiger Moth

Status: Retired: Beautiful flyer for many years. Pull-pull rudder and elevator controls and brushless motor. Duplicate instruments X 2 cut out and glued to instument panel for 2D relief effect. Electric wire shrink wrap used as cockpit coaming.
