I pulled the trigger on this mid-sized glider because of the unique gullwing styled wings and also the Swiss insignia (my wife is Swiss ). The PNP version recommends a 7.4v 2S lipo but I opted to use my own 11.1v 3S lipos that fit well in the fuselage cavity. But since I needed to add a JST conversion adaptor, I carved out some foam from inside the canopy to accommodate room for the excess wiring.

The maiden flight went well and loved the way she handles. She stays aloft catching some thermals, however, as one of my buddies at the field pointed out, she was slightly nose heavy due to the added weight of the 3S lipo. On her third flight, when banking around before landing, she stalled and was too low for me to pull her up so she nose dived and cracked the nose. After the gluing the cracked fus, I double checked the CG and needed to add a washer on the tail to help balance her spot on. Overall I'm quite happy with this glider!

The blank was made by a fellow pilot (thx Mike!) at our field using Dollar Tree foam. Used a can of enamel spray paint I had and added florescent wing tips (Duct tape). I re-used the electronics from my F-22 (RCTimer 2212-6 2200kv; 30A ESC; APC 6x4 prop; 2 TowerPro - 9g servos and 2200mAh 30c Lipo). Hope to maiden her next Sunday since it was too windy to fly this morning.

Now that I feel more comfortable flying 3D, I felt it was time to build a VTOL. StringFly's Flying Sidewinder Missile was the perfect choice!

I've been wanted to get this plane for awhile so I finally did so as my Father's Day present! It's a great lightweight profile balsa that's nice and small for transport. However, I was a bit disappointed that Aeroworks sent me one that had a busted wing rib and the fuse was slightly dented and warped. I didn't want to go through the hassle of returning it so i just sent them an email questioning their QC efforts . Overall, it was a simple build with an easy to read instruction manual. Two exceptions were the rudder/elevator servo extentions that I didn't run through the tight fuse tunnel and also adding two small wood blocks used as my firewall motor mount. If you're not familiar with this plane, here are the stats:

Wing Span = 33"
Wing Area = 348 sq"
Length = 31.5"
Motor = RCTimer 2212-13 1000kv
ESC = RCTimer 30A
Prop = 10.47sf
Servos = TowerPro 9g (4x)
Receiver = HK Orange 6 channel
Lipo = 11.1v 1300mAh 30C (various brands)
AUW = 16.8 oz

Maiden flight went extremely well with no trim adjustments. The wide wing makes this an easy 3D plane for hovering and just about everything else.

I've been searching for a profile EPP 3D bi-plane and finally found this. At first I was reluctant to spend $81+ on a foam plane (no electronics), but now that I've had the chance to maiden her, it was definately worth the purchase. The build manual was in english and was easy to follow which took about 8 hours including the extra paint modifications and installing the electronics. Here are the stats:

- Wingspan = 35.4" (900mm)
- Length = 37.4" (950mm)
- Brushless outrunner = RCTimer 2212-13 1000kv (50g; 150W)
- ESC = RCTimer 30A
- Servos = TowerPro 9g (3x)
- Lipo = Turnigy Nanotech 1300 25-50C
- Receiver = Cheap 6 channel spektrum knockoff
- Prop = APC 10x4.7SF
- AUW = 17.3oz

I kept everything stock except for a modified motor mount which was made from ply glued to a couple layers of foam board. I also applied blue paint on the wing struts, cabane and underside of the lower wing for orientation.

Maiden flight went extremely well with minor trim on the elevator. The ZoomBi has plenty of control surfaces (3" ailerons, 3.5" elevator & entire rudder). She can hover well and perform other basic 3D maneuvers. I would definately recommend this plane to anyone wanting to learn 3D.

After having success with my modified Nasty by making the wing 1" wider, I opted to purchase Value Hobby's Sabre 35 ARF. This 35" 3D profile balsa is easy to handle and a blast to fly. Nice design and affordable!

I needed to replace my previous quiet wing with another. This time, the only modification was a reinforced nose that was constructed with additional strips of FFF under the nose. This support was hot glued and taped which also added the necessary nose weight needed to keep the CG at 7" from the nose.

I came across this easy build delta pusher that can take off and land on water. It flies great but I wanted it to taxi on land so I extended the short water rudder up along the vertical fin. It works great! Hats off to vleisie (Marcel) for the perfect pdf plans!

Now that I'm getting into 3D, I wanted to build another flat foamie that was simple to make using FFF. WaterDog's Nasty foot the bill with only three pieces to cut out! However, I modified mine by adding an inch to the wing chord (tips only), doubling the fus to strengthen it and used a different LG setup. The result was another great 3D trainer that is a blast to fly!

A flying buddy crashed his PA Addiction and didn't want to spend the time to repair it so he gave it to me! I decided to add a 480 equivalent motor from RCTimer (A3530-14 1100Kv) to save costs. But this also meant that I couldn't buy a PA motor mount. Unlike PA's Thrust motor which mounts from behind the can, I needed to rebuild the motor mount to accommodate the standard motor so it would still fit within the cowl. Using scrap balsa and ply, I was able to custom fit the broken mount securely with CA and wires. After logging several flights with this setup, my Addiction still flies great and there's no evidence of stress cracks on the motor mount! Thanks Bill for your generosity!

Time to replace my year-old version one! Added some mods based on the what was done to v1 and changed the LG.

My original FFF version of this didn't fly very well, so now that I have a sheet of 9mm EPP I thought I would give this another try. Alas...a successful 3D trainer (as long as I fly when there's no wind )!

The "noise reducing" prop slot also works well with my new F-22. When flying with other 22" F-22's at our field who have similar electronics & prop setup, there is a noticable reduction in noise with this version.

After reviewing video tests on noise reduction (performed by Otto Dieffenbach), I wanted to see how his proven methodology worked on flying wings. Although the maiden flight had a tough landing, the bowtie cutout in front of the pusher prop worked well. The specs on this wing is the same as my previous build (7x4 prop) so I'll try this on a pusher F-22 next. This is a great modification if you need to fly in areas where noise is an issue.

After experimenting a bit with polyhedral and undercambered wings, I thought I would look for a glider that possessed these characteristics. I found Springer's OSG and decided to add a KFm2 polyhedral wing as recommended by the designer. And painted the underside to look a little like an eagle!

I decided to resurrect my second RC plane, Flyzone's SkyFly2. This would give me an opportunity to test a couple of airfoils, hence "2X" for two different wings! All I had was the original fuselage, three wheels and control horns so everything else needed to be scratch built.

The boom was replaced with a wooden dowel painted black that was secured with thin gauge wire every 1.5" along the bottom of the fuse. New tail feathers were constructed with BlueCor FFF and the control surfaces were enlarged to 2". One wing was a simple polyhedral with undercamber and no ailerons. The other wing was a Kfm2 (top step) airfoil with blended winglets and ailerons. Both wings were shortened to 32".

The brushed motor and other outdated electronics were replaced with an RCTimer 2212-10 brushless (400 size) 1400 Kv, two 8g servos (one 9g servo mounted on the Kfm2 wing for aileron control), 1500 mAh lipo and an APC 7x4 prop. The rudder & elevator servos were mounted outside the fuse along with the pushrods along the boom. AUW was 20.5oz compared to the stock 19.2oz!

The polyhedral wing flew well while the Kfm2 wing didn't get off the ground. I'm thinking I will need to shim up the LE a bit to hopefully give it some lift. I'll test it again next weekend.

Here's an old thread about the SkyFly mods:

I wanted to build goldguy's NutBall while I was charging my lipos. Why? Because I think every scratchbuilder needs to have one! This FFF is a simple build and only took about 4-5 hours!

So back to practicing 3D. I stumbled upon WaterDog's nice full fuse plane built from Blue Cor FFF. Hopefully I can practice those basic 3D techniques and still enjoy a smooth fun flyer for simple rolls and loops.

Since I've never flown (or built) a V-tail prop plane, I found a build thread that inspired me:

I opted for the 26" wingspan version and added my own landing gear. After the maiden flight today, I'm still trying to find the correct trim to keep her airborne.
