Yep, I fell for the pre Christmas hype and then by new years day the bipe was a pile of tripe.

The good:
- Flies fantastic, best foamie I have ever flown.
- Motor is smooth and powerful.
- Servos are very smooth, much better than HXT900s.
- The foam is of good quality, very dense and a smooth shiny finish.
- Very well packaged, despite the birthmark on the fuse left by the carry handle
- Decent instructions, although the suggested throws are a little confusing.
- Control horns etc are all good quality. Kind of Multiplex like but even better IMO.
- Looks soooo sexy, even better naked without those ugly decals.

The bad:
-The decals come off easily, which was not too bad for me because I hate them.
- The LG spats dig in on the shortest of grass. The LG slot flexes too much and compresses the foam.
- Spinner screws are too short. Use servo screws instead.
- Not enough down and right thrust out the box.
- The suggested CG of 95mm is a little far back for most fliers. Most prefer 85mm.
- Oh, and the wings fall off, well rip off really, and far too easily.

Mine lasted 8 flights before the lower right wing tore off during a blender. It fluttered to earth while the rest just plummeted straight down from 10+ meters.

Although the other wings broke on impact the plane held up quite well considering the hard impact.
The breaks were all clean and very little of the foam was compressed.
Even that darn foam spinner survived.

The failure was probably the combination of several...Continue Reading

Scratch built from the ground up in my shed and completed around 13 years ago.
Took me over 10 years to build, so that's nearly 1/4 of a century all up.
Not sad to see her go in the end. No more modified cars for me.
Now I have plenty of money to spend on toy planes instead ...Continue Reading

The originals were built in either float or land versions and won the Schneider cup back in 1925. http://en.wikipedia.org/wiki/Curtiss_R3C

They are a lovely looking plane with some interesting prewar paint schemes to choose from.

Mine was built from a wrecked STA Ryan so it is mostly EPO.
Upper wings Fuselage and horizontal stab are all reworked parts from the Ryan.
Rudder, tail fin, and lower wing are MPF foam.

Specs:
Turnigy 2836/8 1100kv motor.
40A Plush ESC.
9x6 APC prop.
HXT900 servos
1300/3s nanotech battery
Wingspan 780mm
Weight 780g

It's a little on the heavy side so the wing loading is quite high.
Still, it flies very nicely and doesn't seem to have any bad habits.
The motor is plenty powerful and flight times are quite good.
Takeoffs are very short, although it does have a tendency to swing rather abruptly.
Landings can be a bit tricky as it drops very quickly if the power isn't maintained. After a few LG benders I'm starting to getting the hang of it.
Speed is what the original was designed for and this one scoots along quite nicely.
It flies scale like at 1/2 throttle and will do most aerobatic maneuvers at around 3/4 throttle.

This my second build of one of these kits.
http://www.hobbyking.com/hobbyking/s...arehouse_.html

This time I wanted to build a little hotliner so the rudder was not required.
Motor is a Turnigy 2730-3000kv driven by a HK30A ESC.
Battery is 1000/3s and servos 3x HXT500s.
Prop is 5x4 apc, which was cut down from a 6x4.
The battery tray came out of an old Kinetic.
Wings were strengthen using 2 strips of 6x1 carbon glued together. The wings are now rock solid and would carry a house brick.

She's quite fast and very stable. Carries the 1000mA battery quite well and still glides nicely.

I got a bit tired of tying to drill out props while holding by hand, so I built a little jig to make the job easier.
It also ensures that the holes are straight and centralised.

The aluminium block is a scrap manifold I found at work.
All over pieces are either aluminium of stainless.

I use a step drill to enlarge the holes by hand. I find it easier to control than using a powered drill.

The step drill goes from 4-12mm in 1mm steps. Each step is 4mm deep. I still have to get my hands on an imperial step drill.

The T spike thing is used to centralise the prop while is being clamped. Centre hole is 10mm. More than enough for the electrics I play with.

I've enlarged the holes in several props using this jig and each one has come out perfect.

I have a 800mm EPP foamie for practicing 3D but wanted something a little larger and easier to fly smoothly. The HK Yak 55 fitted the bill nicely, is available in the OZ w/house, and is certainly cheap enough.

Build went quite well as there isn't much to the thing. The supplied hardware is quite good and the instructions adequate.
I added extra ply to the motor mount and opened up the battery slot. The wings are glued rather than held with rubber bands.

Setup is:
4x 929MG HK servos
Frsky 4ch Rx
Turnigy 3530 1100kv
Turnigy 45A speedie
1300/3s Nanotechs
APC 11x5.5

This setup gives about 5-6 min playtime. It has plenty of power and good speed. Feels light in the air and can perform most 3D maneuvers quite well.
I tried a 2200 battery but the plane was too heavy to fly nice and needed tail weight for cog.

Great plane and very easy to fly.

I've just finished repainting and detailing my little bronco.

A smoother finish was achieved using a mixture of wbpu and talc as a base coat. Lots of sanding and then a water based grey enamel (house paint) applied using a wide brush.
Decals are from the Durafly Skyraider.
Not scale but good enough for me.
Posted by brett.c | Mar 30, 2013 @ 05:15 PM | 4,051 Views
I scratch built this little Bronco using 3 view drawings and various plans that I found here on RCG. It is built from Model Plane Foam http://www.rcgroups.com/forums/showthread.php?t=1533245 which is a wonderful product to work with, and is much cheaper than depron.

Wingspan is 1000mm and weight around 900grams.
Motors are 2100kv AXN spares from Hobbyking.
Props 6x4.
9g HT900 servos
30A HK ESCs.
8ch Frsky Rx.
2200mA 3s battery.

There is no landing gear so I use a purpose build dolly for take offs and then belly land (I'm not yet good enough to land back on the dolly ).
The underside is covered with fibreglass and WBPU.

This is without doubt the best flying scratchbuilt plane that I've built to date. It is fast, maneuverable and extremely stable. No tip stall tendencies that I've noticed so far, she just mushes about nose high. Looks very impressive in the air and sounds real nice when on full song. Though lower throttle settings can give a rather dissonant warble.

Next I will be adding some panel lines and decals along with an overall coat of WBPU for protection.

Got this from the aus w/house because it was cheap and I kinda liked the look of it.
Typically, it needed plenty of mods just to get the cg right, but I knew that before I bought the thing. Pays to do your research before buying these cheap planes.

Here is the thread where these mods are discussed. http://www.rcgroups.com/forums/showt...2#post23597497 My contributions are on page 12.

I tried flying it with 2200 battery and it was way too heavy. Changed to 1300 nanos and she now flies real nice.

Great value if you are prepared to do a few mods.

I picked up this kit from the hobbyking aus w/house.
http://www.hobbyking.com/hobbyking/s...00mm_Kit_.html

Basically its a knock off of the Merlin/Kinetic.
The foam is quite good and fits together nicely but the hardware is a little crappy.
The ply elevator mech has a lot of slop so I used 3mm prop sleeves as bearings. Works quite good.
I added 3mm carbon to the wing and elevator to help stiffen things up. The supplied fiberglass works quite well at stiffening the fuse.

A hatch was cut in the fuse for access to the elevator servo and I covered it using a cover from a Kinetic. All servos are HXT500s.

Motor is turnigy 2730-3000kv turning a 4x4 (cut down 6x4) prop. Battery is 500mA 3s fitted under the canopy on a balsa tray. Under that sits a 25A speedie.

The plane is fast, extremely fast, and is rock solid to fly. Its way better than the Kinetic thanks in part to everything being so rigid. The kinetic feels very sloppy in comparison. Good glide characteristics too thanks to the small prop.

Flight times are very short at WOT but even at half throttle she's plenty quick enough. Usually I get 5 minutes of mixed flying with a couple of high speed passes.

AUW with battery is 255 grams

So if you're looking for a cheap kit to use a base for a mini hotliner then I highly recommend this one.

Always wanted one these ever since I saw the first review on this thread.
http://www.rcgroups.com/forums/showthread.php?t=1371681

I got mine from the Hobbyking aus warehouse.
The reason I chose the T28 was due it's all round flying qualities, not just its speed.
And to me its more than quick enough on 3s for my local park.

I added a 3mm carbon spar to the wings because they seemed to have a bit too much flex for my liking. Other than some black stripes for orientation and an alloy spinner she's stock from the box.

There is a wide variance with recommend cg but I went with 30mm from the LE edge and she handles just fine.

Nice plane, very easy to fly because it is so stable at any speed.
Also quite fast, even on 3s.

A flying buddy bought this back from Thailand for me.
http://www.ifomodel.com/th/index.php
A couple of guys in the club have their Yak, which is very similar, but I like this one because it is something different. Oh, and it was the only one available in the shop at the time.
They are unusual in having a tapered EPP fuselage which goes from 20mm at the nose down to 10mm at the tail. The kit comes with all the foam surfaces ready to piece together and some control horns, that's it. The rest is up to you.
The manual was in Thai. Lots of n's and u's but a least the pictures were in English.
The motor I chose was a trusty old unit that has served well in many of my planes. A Turnigy 2210C 1200kv, 150W.
Speedie is a Hobbyking 20A Special (nuthin' special).
Servos, HXT900's.
Prop 8x3.8 no name.
I added some extra carbon bracing in the tail section and wheels off some long forgotten hack.
This plane flies very well for what it is. More a sports flier than a 3D ship but it will hover even I can't can't.
Seems very durable too.

I think me and the Sbach are going to have loads of fun together
Posted by brett.c | May 16, 2012 @ 04:04 AM | 5,344 Views
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.

My old Easystar has been hanging from the rafters for quite some time.
Once I'd learnt the fundamentals of RC flying I quickly grew out of it.
I remember RCPowers doing a twin version of the Hawksky and thought it would be a great little project to do the same with the EZ*.

I already had most of the bits for it so it was a simple matter of getting out the knife and setting to work.

Motors are 1650Kv 180W Turnigy 2210As. I have used these little motors before and they perform quite well.
Props are good old 6x4s.
Speedies are a couple of HK20A cheapies.
All servos are trusty HXT900s.

Control surfaces were enlarged and are made from 2 layers of 6mm depron sanded to a taper.

CF reinforcing was added to the elevator and tailplane, and along the underside of the tail boom. I also added a strip of 12mm wide carbon along the top of the wings in order to add stiffness and to flatten them out a bit.

Wings were clipped down to 1100mm. Ailerons are 300mm long.

Battery is a 2200mA 3s which I had to mount much further back. This required a bit of foam surgery around the servo pocket area but not too much. The battery slides in on its side.

I have only had one flight with it so far and I was extremely pleased with its performance. It has the easy flying characteristics of the old EZ* but is a whole lot more precise and manoeuvrable. Speed is quite good, not blisteringly quick but certainly quick enough for me. It still glides reasonably well too, which surprised me.
All in all...Continue Reading

Everyone should own a Funcub. They are such a fun and versatile plane that not having one can leave a dirty big hole in your flight line up.

I bought this one as a goer. It came with a Turnigy 480 850kv, 11x7 APC prop, 40A Mystery speedie, HK933 servos for rudder and elevator, and HXT900s for ailerons and flaps. I use 2200mA/3s 40C batteries.

This set up seems to work rather well. Not over powered but more than adequate for this airframe.

It did have a broken tailwheel mount which had also torn a chunk off the bottom of the rudder. I believe this is a real weak spot on these planes so I used a different style of mount made up from bits from a defunked Katana.

The only other mod I have done is to add a tab (CA hinge) to the battery hatch in order to make it easier to open.

The FC is a fantastic slow flier and is great for laughs at WOT.
Could be a nice easy trainer because you would have to be something really stupid to cash one.
But then again, you can do a lot of really stupid things with this plane

This plane can be bought as a kit from good 'ol Hobby King.
http://www.hobbyking.com/hobbyking/s...dProduct=12914

I bought it because the reviews on HK and here http://www.rcgroups.com/forums/showthread.php?t=1472734 praised its flight characteristics.

Also I wanted a basic EPO kit that I could build up and paint to suit my own tastes. I'm getting a bit bored with all the ARF look alikes.

The basic airframe is quite good and is very solid. Scale details though are totally comical. The supplied hardware is basically junk, however I did use the control horns and pushrods.

Specs.
Turnigy 3536/6 1250Kv.
Mystery 40A speedie.
2200/3s 40C
10x7 TGS prop.
Turnigy 7A ubec
HKSCM9-5 servos (only 5V hense the ubec).
Weight, just under 900grams.
Cg 70mm at wing root.

Mods.
Dual aileron servos (so that I can add some differential if need be)
Firewall added for engine mount.
Doubled up wire link between elevators (too sloppy)
New vacuum formed canopy (original just looks too ugly)
Carbon fibre reinforcing on R&E control rods (they flex a lot)
Reshaped gun cowling (again, too ugly)
Reshaped engine cowling (looks way off scale)
Tapering to the LE of the vertical stab (way too thick)
Reshaping the wing root joint (original has a large step)
Filling the exaggerated panel lines.
Spinner made up from an old 90mm EDF fan.
Added tailwheel in retract position (looks more scale and aids in belly landings)
Digging battery compartment 40mm further forward.

Another great design by Ken, dz1sfb.
http://www.rcgroups.com/forums/showthread.php?t=1542672

Mine is made from depron and has more rounded wingtips, extra stiffeners in the tail and runs on 3s. As a result it is a bit heavier at a little over 300grams.
I had trouble getting the cg right and had to cut the battery hatch as far forward as possible and fit a spinner. If I were to build another one I'd make a short extended nose to help balance it better.

This is a real nice stable flyer at 1/2 throttle but can become a bit of a handful at WOT as it is very fast. IMO 2s is more than enough for this plane.
It is very manoeuvrable and tracks nicely in the air. Slow flies well without any nasty habits.

Nice and quiet too, which is a plus when compared to most noisy pusher type wings.

Specs.
6mm depron.
6mm hardwood wingspar.
2x HXT900 servos
Turnigy 2730 1700kv
20A hobbyking ESC
7x6 Apc prop.
3s 1000mA battery
4ch frsky Rx

Christmas present from the Hobbyking Oz warehouse.

After reading the thread on this thing I thought I'd do the mods before attempting to fly it.

Motor is a Turnigy 3536/8, 1000kv and a 45A hobbyking speedie.
Prop is 10x7 and she pulls 27A static for just over 300W.

I intend to belly land this thing so the drop tank was beefed up with a carbon spar through the guts and some reinforced tape. Maiden flight will be with the LG.

Other than the power upgrade the other major mod was to the battery hatch. The original hatch was glued shut and a new hatch was cut into the top of the fuse. Battery still loads into the original location but through the top instead of from underneath. This makes battery changes a whole lot easier and opens up a lot of space inside the fuselage.

I was sorting through some old photos and came across a few from my control line days back in the mid 70s.

Back in those days my mother had a boyfriend called Vic and he use to take me and a couple of my mates in his big old 64 Pontiac. We could fit loads of planes in that thing.

I dropped out of flying at the age of 18 when owning a car gave you a far better chance of getting a date than a toy aeroplane did.
In fact, playing with toy planes was a sure fire way of ending up only ever playing with something else

So began a long, much too long, love affair with cars, and in particular hotrods.

Now I'm happy to say that I'm back where I began. Plane crazy

I picked this up from a flying buddy who said he was "over it."
It came with landing gear from a PZ Cub along with PZ control linkages etc.
It also had a pair of HXT900 aileron servos.
So a few "issues" with this plane had already been resolved.

One major outstanding issue was the stock motor and ESC, which are of rather poor quality. Recently I took delivery of the FMS 1100mm F6F Hellcat which I intend to upgrade to a 3536 motor and 45A ESC. The F6F's 900Kv motor and 30A ESC were removed and fitted into the Extra.
Prop is a 10x5 APC on a parkzone prop adapter (it was all I had).
With a 2200/3s battery no additional nose weight was needed to hit the cg (90mm from LE)

I've fitted HXT900's to the rudder and elevator and larger diameter wheels for grass takeoffs and landings.

Maiden (for me anyway) was on a pretty windy day however she flew rather well and was very precise and manoeuvrable. Seemed to have loads of thrust but the speed was a little slow for me. I might upgrade to a 10x7 prop.
I can't 3D to save my life but with the rates dialled down this plane is docile enough to be flown like a sports flyer.
