Well, in a moment of weakness, I shelled out fifty hard earned bucks for this model in HK's Xmas sale and, I must say, it was money well spent

My local park is a bit noise sensitive and, apart from being an abomination, I always intended to replace the EDF unit with a nose mounted motor and folding prop. I did this by back mounting an outrunner to a ply firewall and gluing the whole shebang into the fuse.

Set up is:
Motor: HK 28-30S Propdrive 800kv
ESC: HK 40amp Plush
Prop: aero-naut 10x8 folder
Battery: HK Nanotech 1300mAh

I will drop the supplied EDF unit and ESC into something else.

The weight of the motor and prop on the snoz necessitated the battery being placed back under the trailing edge of the wing. I opened up the lower fuse and was pleased to find a perfect channel in the fuse to take a 1300 battery.

The model is mildly aerobatic and thermals like a champ. With the folding prop on I expect it will be a nice sloper too. Here's a short vid, just cruising around down at the park.

I have been flying my Luft '46 Horten Amerika bomber for ten years and she was getting a bit tatty, so I stripped her nekid, strengthened the framework a bit and gave her some new glad rags.

Here's a vid of the maiden flight following the makeover.

So I thought I would dip my toe in the canardly pursuit and see what all the fuss was about

I chose a rather old design called a Canardex, built from a plan, as it has a relatively simple balsa construction and looked pretty tough, so would make a good trainer.

The model has been built with a 3S set up running on a 1100mAh battery, 25 amp ESC and 1100kv Turnigy motor with a Multiplex Xeno 9x6 folding pusher prop. These props are really neat (particularly if you are planning on doing a bit of slopin') for 3S pusher applications and, being specialized pusher/folder props, they don't over-rotate forwards or backwards.

Here's a vid of the maiden flights with a bit of AP. Crank up the HD to 720.

This model caught my eye when I was looking around for a scale 2.5m motor glider. It's a MotorSpatz (MotorSparrow) from VQ models in Vietnam. The fullsize was designed in Germany as a powered version of the existing Spatz glider and was first flown in 1960. Around 50 were made and a few are still air worthy in Europe with a couple flying in the USA.

Really nice flying model and a pretty straight forward build. I sourced the model from here:

Here's a vid of the maiden and second flights - on the second flight I tacked a Mobius camera on the l/e of the wing and have spliced some AP footage into the vid.

The previous blog entry recorded the maiden flight of my NPS thermal glider from TheBuildRC. I took it out to the beach recently for it's maiden slope flight - just left the pod on and it flew really well.

Here's a vid - the whole flight was unpowered.

I finally got my eagle ready for his maiden flight recently and took him out to the beach. He's still nekid at the mo as he has to earn his feathers by flying well and this is not always the case from what I have seen.

I deviated from the plan a bit in giving him a v-tail set up. This works as a ruddervator mixed at 80% to the ailerons. He is fitted with drag plates on the ailerons to aid in cornering. There is a bit of a trick to using these in that you don't want them extended for too long as they can grab on the air and cause an over-rotation. So, you just use them sparingly and "fly" the model through the turns using small inputs to keep the turn as smooth as possible.

Here's a short vid of the maiden - pretty low key stuff as I was just getting a feel for it and flying this model normally is pretty much a full time job. Excuse the bush landing, the wind was dropping off a bit, there were people all over the normal landing area and I couldn't get enough height to go over the back so decided to plant it in the shrubbery.

Took the E-Zulu out to the beach the other day and had some great sloping flights with it - really love this model :-D

All flights were in gliding mode - you can watch the vid in HD at Vimeo.

My PSS Spitfire sloper has recently turned four and a half years old, which is gettin' up there for a foamy sloper. It has done a lot of miles and is a veteran of some brutal landings, but is still hanging in there.

Shot a bit of vid out at the beach the other day - it was a nice sunny day, but the wind speed was 10 to 12 kts and the Spit likes 20 to really kick loose, but was very pleasant flying conditions. You can watch the vid in HD at Vimeo.

I recently assembled a Zulu aerobatic slope glider from Zupair.

RCG thread is here:

The Zulu is a very agile sloper that gets a helping hand from leading edge drooperons and also can be built as a powered park flyer by virtue of having a fire wall and detachable nose cone incorporated in the design.

I went with the parkflyer option, using the motor and prop from the HobbyKing Wingnetic which resulted in the battery being positioned on the cg. The model will still perform very well on the slope with this set up and can be thermalled.

Very fun model to fly. Here's a vid of the maiden flight - just cruising around getting a feel for the model. You can watch it in HD at Vimeo.

Well, by a somewhat circuitous route I managed to end up with one of Alex Louw's moulded gulls and maidened it last weekend in around 20 kts which made it pretty frisky.

Flew really well and I had trouble getting it to come down low enough for my head cam to capture it. Struck a bit of a problem with elevon flutter at (very) high speeds, so I will have to address that, but otherwise a great flying model. I added an elevator, mixed with the elevons.

Here's the vid - click on the Vimeo icon to watch it at Vimeo in HD.

Very fast little model so a bit hard to video - will try again on a sunny day with a bit less wind so I can slow her down and bring it in a bit closer.

This is my 20 years old 3.5m Hi Phase glider following renovation, which included recovering the wings and adding ailerons as I want to use it for ridge soaring as well as thermaling and club/park flying.

Well, I have been flying the Vag for six months and it is still going strong. Takes a likin' and keeps on tikin'. Fun model to fly and Hacker has a whole bunch of new stuff coming out - new colours, SFGs, a larger Vag, a motorized option and some scalish models built off the Vag concept:

I decided to electrifying mine to get a bit more stick time on.

Flies really well and still performs well on the ridge. In fact, it is better in some ways in that the flight envelope is expanded and only the most extreme VTPR aerobatics are effected a little.

Some guys I correspond with asked to see it flying, so I made a short vid. The model does some neat flat spins and a few other tricks under power, but I tend to do them fairly high up as I often mess them up and they were too far away for the head cam to pick them up clearly - so this is just some low and slow stuff. You can click on the Vimeo icon to see it in HD if you want.

So, I liked the look of the ZETA Science FX-61 Phantom FPV flying wing, but wondered how it would go with a wider wingspan. So I ordered a kit with an extra pair of wings and set to grafting the extra wings to the standard airframe. With a large dose of cf spars and a bit of glassing the job got done - extending the w/s from 1.55m to 2.6m. I then covered the model in brown paper and TowerKote and fitted a 600W 4S 4000 mAh power system. As a large part of the new wings were behind the cg I moved the motor from the rear to the front to save weight. A few decals and she was ready to go.

The model weighs 2kg RTF and will be used for general roust about flying and ridge soaring.

Been working on the Ogar recently and took it to the beach for its maiden flights. She's built pretty much stock. I added some cockpit detail and pilots and strengthened bits here and there. Flying with a 2200 battery and 44g of nose weight so could go up to a 2500 or so as the battery is currently all the way forward.

Fun model to fly and certainly looks different in the sky. Great park flier, thermaler, sloper and AP ship due to its RES (rear electric sustainer) set up. It has also become popular with FPV dudes o/a of the large space in the forward fuse:

Here's a vid of the maiden flights.

In the first part of the vid the model is just cruising around close in at a quarter throttle and then we head out to the ridge.

Hobby King are still selling the 2.4m version of the Habicht with the 2.6m available from the Aussie and US West warehouses.

I was never very keen on the 2.4m version due to the frail fuse, but one time in a Cyber Monday sale HK had them for sale for a few hours at $40USD so I thought "What the hell". For that price I could spend a bit of time knocking it into shape.

Got around to working on it recently and made a few mods to strengthen the fuse with some extra bracing and ripped all the innards out of the front section and laid in CF cloth, then put everything back plus added a deck for the battery and nose weight.

Will see how well that holds up over time.

Rest of the build was pretty straight forward and we were done.

I picked up one of these recently on a bit of a whim as I liked the powered glider set up it was designed as and have access to some neat slope sites to fly it at.

Here's a vid of the maiden flights. First flight was behind the ridge in a 10kts turbulent breeze, then out to the ridge in 15kts. Really a neat model to fly.

I have flown it several times recently in fairly calm conditions and have really been enjoying it. Very good bang for a buck.

We had a brilliant summers day yesterday so I took the opportunity to take the Kate out for her first sloping session.

Had some mates along and some "interesting" spectators made for a fun filled day.

The spoliers I recently installed worked very well. You can see at the end of the vid the Kate dropped in about 50m short of where I would normally have expected it to land, but there was a bit of a head wind so it will be interesting to see how they perform in calm conditions.

One of my favourite slopies is the Calypso Cobra.

This model is somewhere around 16 years old, still going strong and always puts a smile on my dial.

It's an F3B model and has been to the world champs in Germany back in the day. F3B models are intended to be winch launched, but these are rather brutal affairs and my Cobra has had more than a few repairs done to the wings over the years so I would not be happy subjecting it to the stresses of a winch launch. The wings are hollow and, if the leading edge ever splits on a winch launch, the result is a catastrophic explosion of the wing.

So, I wanted to get a bit more stick time on her over summer and thought about attaching a SLS (self launch system). There is zero spare room inside the fuse so the whole mechanism has to be in a self contained pod attached to the wing at around the cg point to maintain correct balance.

Had a hunt around and looked at some eye wateringly expensive set ups. I had pretty much decided on making my own when I stumbled on one a German chap had developed himself and was selling online as the Lifter:

This was sort of what I was after, but had the disadvantage that it could only be used once, then it collapsed and had to be reset manually on the ground after landing. Not a biggy, but I figured that the Cobra is such a brute of a thing that it should still fly well with the pod raised which meant you could get maybe four climbouts from each...Continue Reading
