I've been lucky enough to have found the early Spitfire and the FW190.
All boxed and complete from the factory.
Naturally I've modded both aircraft to 2.4ghz and I've converted both wings to twin servos for the ailerons.
I upgraded the elevator servos as the originals were the 5 wire units.
I've kept the original motors and gearbox assemblies for now as I didn't want to start cutting the perfect fuselages around as yet.
Perhaps in the future, if the motors give up then I'll carry out that mod too.
The models had been stored for so long that the joins on the fuselage half sections had started to come apart so to cure this I ran PVA inside and allowed it to settle itself into the join throughout the whole of both models.
Aside from this the finish is perfect and the mod with the ailerons to the Spitfire are not too bad considering I had to surgically remove the factory snakes from the underside of the wing.
This left a trench for the new servo wires and I manged to seal the join in the covering with clear tape.
I also used the wing tip protectors from the packaging to help save the beautiful eliptical wings for as long as I can.
The FW190 was easier to modify with the wing servos as the section is much thicker and allowed the wires to be routed through the inside.
The original roundels on the Spitfire cover the servos and home made crosses hide the servos on the FW190.
Both aircraft now have Turnigy 30 amp brushed ESC's for the original motors and Turnigy 2200mah 25C lipos provide the CG and plenty of grunt to get them flying superbly.
I don't like the sound of the gearboxes but the trade off with excellent flying and now quite rare Parkzone originals makes up for the "Toyish" sound that they make

These are a great fun little plane for either indoors or outdoors.
The piYak build thread can be found here http://www.rcgroups.com/forums/showthread.php?t=1226187
Mine is made from 9mm EPP and is the 18inch version.
It has a Turnigy 2730 1500kv turning a 8x3.8 prop.
Speedie is a 10A HK version.
All servos are HXT500s with arm extensions on the elevon servos.
I find it quite easy to fly and it can goof around in a small area at very slow speeds. I haven't quite got the hang of hovering but she is more than capable.

I needed a 12V power supply for my new charger. After looking around at high priced power supplies I decided to make my own power supply.
Here's the temporary power supply I came up with. I say temporary as I will mount it into a case and I will be adding a temperature sensor for the fan unit. A little soldering and a couple wires later this bad boy is rocking out so REAL power!
The specs are as follows:
700 watts
57 amp
110 volt or 220 volts
This unit will allow me to run 2 - Bantam 902 chargers and charge 6 - 4S batteries at the same time!

This is a picture of 1 or the 2 Octocopters Chris Bergen of Bergen R/C Helicopters has designed and is currently building for myself and another person.
The octo has OS30 motors and DJI WooKong M (WH-M) flight control.
The camera mount is gyro stabilized and designed by Jody Prather of HeliCam Solutions to carry a 5D camera. My camera mount is slightly smaller for the Canon T3i camera that I will be using. The retracts are supplied by Bill at Spring Air Retracts and redesigned to accommodate the Octocopter by Jody Prather of HeliCam Solutions. Chris Bergen took these photos of the build progress.
Thanks and hope you enjoyed the view! More pics, test flights, and AP photos to follow.

My Best 3
Had a blast but flying for a fixed camera is tough.
| My 3 Best.wmv (13 min 25 sec) |
Cleaning out the work bench and found 8 RCTimer 20A ESCs. 3 are still in the wrapper and 5 are out with 3.5mm female bullet connectors soldered to them. On 4 of them with the 3.5mm female bullets, I separated the signal wire from the +/- on the RX/BEC connector to clean up the install that was going on a quad that had the FC powered by a separate SBEC. I am including 4 servo extension wires that you can cut off the female side if you would like to switch the 4 back so the RX/BEC connector has Signal/+/- wires.
These were purchased approximately 1 1/2yrs ago and are in very good condition. No issues whatsoever.
Would like to get rid of the all to 1 buyer.
Have no trouble shipping out of the country.
$85 shipped for all 8 in the US, $90 shipped for all 8 out of the country

FunCub upgrades!
Well I took the plunge and ordered the articulated landing gear set for the FunCub from cublandinggear.com! He's currently on vacation at a float fly in eastern Washington so the order won't get processed until next Monday. I haven't decided if these will go on this one or maybe a second FunCub!
Getting ready for a float fly at Camp Far West next Saturday, Hopefully I'll come back with something to attach that gear to!

5.13.12 Two more flights at Pierce Airport (closed)! Well, I got a bit cocky - and it bit me in the butt! Shooting approaches and making passes at a camera on a tripod. I had a near miss on one pass and then tried to get down on a bad approach, landed long, and rolled out into the tripod! I got lucky - just a dented leading edge and a broken strobe light, it would have been nice to see them light up in the air just once before taking them out!
The flight took place on 5.13.12 and it was my 13th flight!
5.12.12 Went a flying at a field called Crazy Creek! What a great bunch of guys and what a phenomenal place to fly! I took out three batteries and the guy I flew with had five my size, and brought them along for me to use! Went thru his five figuring out flight times (we figured out 12 minutes is safe), I'm actually a little tired and I still have my three for this evening! No damage, no close calls, just pure FUN!!
5.8.12 I'm 52, I don't say 'dude' but - DUDE this planes a hoot!!!
I had three wonderful flights with absolutely no problems and she lands like a dream! She's like my Mini Super Cub but better - easier to fly and land and much more capable!

After all, he got me started in RC flying back in the early 80’s. It is built mostly stock except for the modified tail wheel tiller. I sewed the tiller to the control horn using Kevlar thread. It works well. I am not a foamie lover; however, this is the best flying RC plane that I have flown. The Suppo 2814/8 1000kv Brushless Motor with an APC 11 x 5.5 flies this Fun Cub with authority.

Second flight and still driving me crazy with the diving like it's still nose heavy. I know the video says tail heavy but I meant nose heavy. Third flight I removed the 808 #16 camera from where it was to move it back, but the velcro wouldn't stick anymore hence no video of the third flight which went way better. CG looks good on the ground but in the air it still needs some up trim to fly level at full power. Now I think the motor has too much down thrust and the solution is to tilt it up with some washers. I'll put the incidence meter on it later to confirm the degree.
Here is a Super hurricane 24 I bought to a French on ebay obviously in "very good state " .. ..
Cosmetically, it is in good state , also are the points , cylinder sleeve, piston .. There is a but .. As you can see on the pic, the crank has been seroiusly hammered .. Why ?? Also has been the crank pin .. That you can' t see on the pic, but the rear diameter is bigger of 1/10 mm than the rest of the pin ..
For the rest , it is like I could expect it was : the main bearing is worn out , 2/10 mm ( as far I know, this is a problem on this motor ) , also is the rod, on the 2 ends , also is the piston hole .
So I will regrind the crank pin to 4.6 mm , set a bronze sleeve in the rod . The upper part of the rod will simply be reamed to 3.4 mm instead of 3.17 when new. So will be also the piston, after that , I will set a new piston wrist 3.4 mm .
Also I will set a new main bearing, dimensions as new ..

Just another fine day with the Pitts...
Near perfect evening + 70F/21C+very cool RC plane+empty soccer field = a WHOLE lotta fun! 
My Pitts went up in the late evening. A fellow was fly casting for practice earlier in the eve, and I did not wish to risk getting tagged on the way down! It would make line RC a whole new thing!
Anyway, it was great. Just one quick 7.5 minute flight, and an awesome TD. I did a few loops a roll or two, a wingover, and some general cruising. Consumed 1550mAh of available 2100mAh (75% LVC on a 2800 battery).
So, I should be able to do around 10-11 minutes flying like that, around 50% and then 75%-80% on manouevers. The kids just love this plane! It's a winner, and one I hope to fly much more this summer. I am just finalizing the CG issue I had in earlier flights to get the plane a bit closer to ideal. Almost have it!

1) Pilot-on-board for pure fun such as some single seat ultralight, sailplanes.
2) Mainstream sport kits; http://www.advantagehobby.com/?cat=165
3) Scratch built FFF;http://www.rcgroups.com/foamies-scratchbuilt-428/
'Real Airplane': An aircraft used for a purpose, a tool to get a job
accomplished.
examples:
1) Private aircraft as transport or competition.
2) Military combat aircraft, RPV or pilot-on-board
3) Private aerial photography; fence line checking, real estate, search and rescue.

Bought the parts to assemble this Flyzone Micro Albatros WW1 in the fall of 2010. Hard to pass up on them at about $20 total; plus I didn't want another transmitter to mess with. Had the mono-wing racer ready to maiden February of 2011 and it flew not-terribly. Took some tweaking and radio mixing to overcome the known asymmetrical rudder response of this Albatros design. Also needed to keep the flying speed up.
By April of 2011 I was ready to try the biplane Albatros, which flew nicely overall. I adjusted the rudder-->elevator mixing and moved the battery more toward the nose to counter the higher moment of lift.
In anticipation of the Flyzone Triplane introduction I added a third wing to my Albatros in October of 2011. Again tweaked the mixing and CG location. Also reduced the rudder throw as it is now very effective. I continue to fly this triplane with a 120mah just behind the propeller. Since I still haven't added much detail it is nice and light with flight times of 12-13 minutes common.

- Installed a 3-channel Brick from parkzone.
- Uses a GPS-7 gearbox and motor from Hobby King. This required lots of rework to make reliable. The 7mm motor died very early and now has a SS red end bell. Soft metal prop shaft replaced with 1mm music wire. Added a GWJ Universal prop saver from BSDMicroRC.
- Flying with a GWS5030 prop reduced to 4.5" diameter.
- Tires were donated from an Ember 2.
- Wing bracing, landing gear, and pushrods are 0.020" music wire.
- Extra foam from food take-home trays and small foam plates.
