Some fun down at the park with my scratch built delta ridge soaring glider converted to electric. I did it up in French livery as it had a sort of Miragish look about it. It is powered with a geared Astron motor, 2500mah 20/30C Hyperion battery and 50 amp Hyperion ESC and still flys well as a ridge soarer.

When I was getting close to finishing my last build - the DH1 (details here: http://www.rcgroups.com/forums/showthread.php?t=672333) - I started thinking about my next project. As the DH1 was a slow WW1 bipe I thought the next one should be a fast pusher jet. I have always thought that the SU-27 Flanker (and its numerous derivatives) was one of the most aesthetically and aerodynamically appealing designs ever created. It also has that cold war "ememies hardware" attraction. So the model was sorted, now for the colour scheme - so many options to chose from, but in the end I kept coming back to the Ukrainian Air Force demonstration team’s Flankers with the cool racing stripes and splinter camo.
After spending three months on the DH1 I wanted this to be a quick build and had a look at a few Flanker kits and ARFs around, but in NZ freight cost is always a PITA. I was fortunate in that a flying acquaintance of mine has made a few Flankers for other flyers in the past. He very kindly knocked me up an ARF body that is a work of art and slightly over 1m long. I powered it up with a Multiplex Permax BL-480/4D, Hyperion 2500mah 20/30C battery, Hyperion 50amp ESC and 6 x 5.5 prop. Haven’t had a radar gun on it yet, but the same set up on my Stryker takes it to 150 kmh. Added a cockpit, canopy and pilot, a dob of paint and some decals I made and she was done.

I have always had a hankering to build a DH1 or 2 as their shape is unusual and suited to electric flight. After some searching I found an ARF model made by LX Models . Their standard DH1 model has a 76cm wingspan, but I managed to source a 1.0m beastie from a model shop in HK. They apparently make a 1.3m model but I couldn't find one anywhere. The LX website is pretty toxic and they never answered my e-mails. I must say I am very impressed with the quality of the model. The only gripe I have is that some of the linkages were a bit basic and attachment methods would not have lasted five minutes in flight. Just replaced them with some quality hardware.
Off and on it took me three months to build the DH1, the most time I have ever invested in a model so I was rather relieved when she just climbed away on the maiden flight as though it was the hundredth flight.
It flies brilliantly with excellent control responses. With 4 ailerons and the tail controls right in the slipstream she is very agile. Does nice loops but is a bit reluctant to roll - more likely a technique I will have to learn. It does pretty well though as I guess the original was never designed to roll at all.
Some pics below.

The latest dent in the bank balance. This model is a shameless knock off of the KingCat turbine, right down to the commonly used colour scheme, but is sure a fun model and is a real blast to fly. Hopped it up a little from the recommended set up with a Multiplex Permax BL-480/4D, Hyperion 2100mah 20/30C battery, Hyperion 50amp ESC and 6 x 5.5 prop. Haven’t had a radar gun on it yet, but the same set up on my Stryker takes it to 130 kmh so it should be in that vicinity. Other mods were mainly strengthening to take the extra Gs and the addition of larger wheels and a pilot. Thread and review links are here:

I purchased an elliptical wing glider as a crash wreck recently for 20 bucks.
Had to strip off the old covering, repair about 20% of the framework and recover with tissue and dope (my first experience of this). Read up techniques on RCG and was quite pleased with the finished result - rather fragile covering though so have to be careful handling it.
I recalled that the Horten brothers built an elliptical wing glider which they called the Parabola, so decided to do this model up in German markings to represent what a production powered version of their Parabola might have looked like as a reconnaissance bomber.
She’s powered by a Hyperion HP-Z3007-26, with a 2500mah 3 cell lipo and 30 amp ESC generating 245 watts. AUW with battery is 2.1 pounds so she motors along nicely.
Its amazing what the Horten’s managed to do without the aid of a computer or advanced materials. My Parabola cheats a bit by having winglets, but they look cool and make it very stable. Glides extremely well and is much more manoeuvrable than I thought it would be, some pics below.

For my second balsa build I chose the relatively straight forward Little Stick. Motor is a Hyperion HP-Z3007-26, powered by a 2500mah 3 cell lipo and 30 amp ESC. Does a nice rise off ground and has proven to be very aerobatic. Comes in pretty hot, but I am getting better at nailing the landings and it sure is a tough design so can take a bit of rough handling. Final touches will be a pilot and machine gun stapped on by the rubber bands securing the wing.

This is a scalish model of a Beagle Pup that was originally flown as a gas powered control line model. I have just finished an electric R/C conversion and she flys superbly. Motor is a Hyperion HP-Z3007-26, powered by a 1750mah 3 cell lipo and 30 amp ESC. Does a nice rise off ground and is way overpowered so flies for about 20 mins with a bit of throttle management.Very sedate flyer, but certainly has a turn of speed with this set up and looks very scale on fly bys. The Pup was used by the RAF as a trainer for awhile and the colour scheme of this model is based on a civil registered one still flying in NZ.

After putting together 16 foamies and electric conversions of balsa models others have built I felt it was time I bit the bullet and tried a balsa and film build myself. I chose the 1/2A Lanier Shrike as it is quite small and has a delta shaped wing that should not be prone to warping. Build went well and I learned alot along the way (mainly by doing it twice) and have had great fun with the finished product. Its powered with a RCer Warp 4, 50amp Hyperion ESC and 2200mah Lipo. This gives it quite a high wing loading but it as an absolute rocket ship. Its very unforgiving however and I might down size the set up at some stage to reduce the wing loading. Some pics below:

My flying club had a float plane day last weekend which was a huge success with flying from 9am till 4pm. With all that activity it was inevitable that some of the flyers came to grief. Heres just some of the incidents that were caught on camera. In follow up blog entries there are some additional pics of the more successful flying Enjoy.

Motorised Alula: got abit tired of chasing my Alula around ridges and parks so put a small Hyperion motor set up on it and transformed it into a soaring eagle. Flys brilliantly, is very aerobatic and still ridge soars nicely with motor shut off. Terrorises the local bird population. When the folding props are back against the fuse you can't even see the motor in flight.
Motorised Graupner Mosquito: 2.5m wingspan with detachable motor mount. Glides beautifully. Will make a better looking mount sometime as the prototype was fully adjustable so I could sort out the best thrust angle to max out the climb rate.

Had a rush of blood to the head awhile back and thought I would see how my Outrage performed as a float plane. The standard GWS floats (for the Beaver etc) are just the right size. Handles well on the water as the rudder has a lot of authority due to its size and flying performance is about 75% of stock. Has a real short takeoff run and is a barrell of laughs. I just used the existing undercarriage with some c/f rods c/aed in place. Some pics below, together with some links to a couple of vids that inspired me:
