Was just watching TV today and spotted this toffee ad.

Hmm...seen this someplace before.

Another glorious perfectly calm day with blue skys. Almost don't recognise the country I'm in. If this is global warming, please burn more oil

Yesterday I flew on St. Annes beach and was followed by a camera crew filming a chap sat in a green leather chair being served by a dish on a silver platter...which is a bit surreal. Me buzzing them with the hawkeye probably didn't go down well.

When I came into land i just managed to miss the dry island of sand I was stood on and the Hawkeye got a light dunking in salty seawater Damn speed controller...battery had plenty of power left but it entered a soft cut-off mode and I just couldn't make it the few extra feet. No damage just a lot of wiping to remove the sandy spray.

Amazing flying weather today which makes a huge change from the recent dull, wet and windy weather in the UK.

I've been trying out my Hawkeye over the last few days on and off between the showers. It's been a struggle sometimes..despite the inviting blue skys and apparent low winds the weather has turned out to be much better suited to my easystar with high level gusty conditions.

Finally today it was perfect and so I nipped down to the notoriously magnetic Lytham windmill for some AP. Despite forgetting to set my camera to infinity it managed to pull off some fairly decent shots. It was also a pity it filled up the memory card and missed the low passes over the life boat station and life boat pier. It also missed an awesome Tornado fighter pass that gave me the fright of my life as it buzzed the Lytham coast.

I brought the Hawkeye into land at one point over by the lifeboat station carpark. This was a tight spot and I wasn't able to land into wind. Came in a little hot and fast with too much height. Had to dump the height fast and the fast rollout would have meant a heavy impact with the building if I'd not been standing directly in front of it. It came to abrupt halt against my hand with gasps from onlookers who thought moments before that it was a full sized ultralight coming into land. Very cool!! But what I didn't know is my camera managed to eject it's battery door and battery in the sudden deceleration. So a little later I was flying around trying to set up...Continue Reading

Slowstick is still going strong and earlier in the year I got it up to 2500ft as registered by the onboard altimeter (Eagle Tree).

The intention was to clear the sails and make a left bank around the back of this 18th century listed building but a major depth perception issue caused the turn to start a little early.....

Slowstick / Windmill...Fight!!! (2 min 51 sec)



The servos shunted forward on the stick due to the initial impact and pulled both connectors out of the rudder and elevator. That just left throttle and two loosely flapping control surfaces. Came down gently enough but nosed it in at the final second.

The only damage to both slowstick and windmill...one broken prop.

Picked up a Flytech Dragonfly cheap a few weeks ago. Always fancied an ornithopter of some sort and I'm pleasantly surprised....Well actually....its AWESOME!!!!
Just needs a bit of nose weight to stop the stall/bob and I'm really having a lot of fun doing circuits around my garden, occasionally dive bombing the kids who like to chase it and it's great to get my dad involved - he loves to to take snaps of my flying toys.

The only thing I'd add is some form of elevator control...maybe a servo or actuator on the tail to adjust cog. Has anyone done this?

Heres some of the pictures taken by my dad. Not exactly great conditions to fly.....still very cold and in the dead of night - it was very hard to see - but he insisted so.... ...Continue Reading

Not been doing any flying this year.....weather in the UK was terrible.
Heading into winter I've started to miss the fun I had last year, grabbed a slow stick to build into a decent AP platform which I probably won't be able fly till next year.

The Hoverdisks were tonnes of fun but are tricky to store and transport. I'll let you know how the stick goes and I'll stick up some pictures just as soon as its ready.

Meanwhile I got into tanks....yep tanks.....those slow heavy garden munchers. Not sure how tanks are going to fit in with my website but I'll think of something.

Its just a cheap HengLong ebay German WW2 Tiger 1 but now much upgraded from a cheap plastic toy to a real heavy metal monster. I can never leave things alone

Low passes over spikey bushes, with hindsight, was a dumb idea...

Video here

Bit of vibration on the vid but hey...I don't need to fix it now.

Bust up the mini-disc too. I felt it was a bit nose heavy so I pushed my rx back and it ended up permanently wanting to sit on its tail. Had the power with the little Feigao to head for the stars but ended up upside down and into the ground. Chipped a corner off one of the elevons but I managed to continue to fly it and eventually tame it. The big disc is soooo much easier to setup....well it doesn't really need any - just tends to fly right from the off no matter what the hardware, CoG or weight so I'm just going concentrate on getting Hoverdisc No 3 in the air.

Flew my big disc with the GWS 15T and 800mAh 3cell yesterday on a 7x3.5 prop. Flew really nice.....gobs of power, lots of hovering, harriers, vertical take off with half throttle and just general extreme slow flight. Only 10 minutes flight time though before sudden unexpected LVC.

I want more from the one battery so I'll stick on a 6x3 prop which will hopefully still give me adequate performance. Having said that, the figures for that prop on that motor on the GWS website suggest not. The numbers look a little screwy to me which I've queried here.
Basically its saying that a 6030 produces less thrust at 11.1v than it does at 9.6v and yet pulls more current than a 7035 prop at 11.1v.

Less hovering also will help the flight time but I just can't help it. Its soooooo much fun

I had a go with a my heli's 2.1Ah 3cell battery. Carried it fine but of course at 150grams along with a 1oz camera it lost all of its nice floatyness and vertical ability - wasn't much fun. The hoverdisc flys much better when its sloooooooow. Now if I'd taken the camera off...

Meanwhile a new servo came in to replace the intermittant one on my minidisc so should have that up and running over the w/e.
I'll prop it down aswell....with so much power in reserve I should easily be able to drop down to increase flight time without compromising too much power. Have never had a full flight with the mini disc so far, so I have no idea what the flight time is anyway. Hopefully will find out soon.

....and another thing Damn camera is playing up again. Cutting out after a few seconds of video. Had this problem some time ago but resoldering the battery connections seemed to fix it for a while. Maybe the battery is on its way out this time. Damn nuisance. Ho Hum.

I've had a couple more flights with the mini-disc. None of them good so far.
IPS with a pixie7p was a disaster. It works well with the GWS brushless 15T though if you keep the weight down and the amp draw low. Couldn't quite figure out why it was handling so strange until in one of those 'one more go' moments it ended up embedded in a spiky bush. One servo was severely chattering away to the bush but the bush wasn't interested. When the minidisc was finally released the other elevon servo apeared to be dead. I figured it'd burnt out but a sharp flick brought it back to life. Ah! this is why the minidisc was behaving so badly in the air....basically I was getting a roll everytime I dialed in a bit of elevator and aileron was not nearly as effective.
Took the servo apart and resoldered internal motor connections but it appears to be the wires that directly enter the motor which are a bit tricky to access. So another servo on order.
Meanwhile I installed a 12mm Feigao and 3cell 360mAh battery and with the dodgy intermittant servo I gave it another go...mad or what?
Sure enough the servo died mid flight but I managed to keep the minidisc flying. The Feigao with a 3cell and 10x4.7 prop has gobs of power. Anything above half throttle and the minidisc went vertical...but with half of its elevators gone this was sudden uncontrollable roll/spin territory. The best solution I found was just to float it around with a nudge of throttle and gentle rudder control and most of all...Continue Reading

Finally got out and maidened my mini RCDisc (as it's now known - damn lawyers ) on a damp, overcast, cold evening with the light quickly fading. Initially I tried a 7x3.5 prop on the GWS brushless 15T motor and together with a heli 25amp ESC and 1200mAh Lipo it flew not very much like the big floaty 3' disc. Did someone say fast??!!!
After some quick passes and general 'getting a feel for it' I decided to bring it in. The trouble was that the field was chock full of cow pats so there's no way I was going to let it touch the ground and it wasn't going to easily float into my hand like its bigger sister. This mini disc was coming in hot. It was like a moment from a USAF carrier operations training video showing F16's being snatched out of the air. The main thing is I got it home excrement free....well apart from maybe on my shoes - well its only cow poo.
Next day I switched to an 8x4 prop with the idea being that I could slow it down with high pitch and prop hang...but I'm still giving it full throttle as a hangover from many a practiced geared 350c launch. Bad idea.
It was quite a shock & awe moment as it shot over to the other end of the field before I'd finished the throwing action. Had to make a severe hard turn to avoid the hedges and then it was back over to me in an instant....hard right to avoid my head....AAAGH tree!! throttle full, full elevator, scuff the top branches and finally I was off into the tupperware lid grey sky giving me just enough...Continue Reading

Finally.

In between family holidays, birthdays & days out I managed to put together the mini hoverdisc kit that Tom from www.rchoverdisc.com very kindly sent me after the untimely death of my first disc.

Tom sent me a shed load of Overbreak Hoverdiscs of both 3' & 2' variety but I decided to try out a build over a 2' clone-disc that I picked up from a local bargain store. The Overbreak 2' disc uses a much thinner fibre glass rod than the original 3' disc and requires a rod extension to pull excess material taut. This clone disc uses a full sized rod providing a stiffer structure and the material is taut from new. It does however seem to be a slimmer saucer profile so it's most likely to be a bit faster and a little less floaty than Overbreaks disc*. Time will tell.

[*Edit: I finally got round to modifying the Overbreak 2' disc with a thick fibre glass rod from the 3' disc cut to the correct length to pull the material taut. I was surprised how much slack I was able to take up and gradually the oversized inflatable cushion look was replaced by exactly the same slim line aerodynamic profile of the clone disc.]

After an experiment with 3M dual lock velcro-ish type stuff I eventually opted for a mixed foam backed double sided sticky tape and hot glue build. I've used dubro-esque ez-style connectors for the tail feathers with a couple of cheap/light 5.6 gram Tower Pro servo's and an HS50 nicked from my heli. The servo's are routed up to my trusty R700...Continue Reading

A parcel came for me today....Tom from www.rchoverdisc.com sent me a whole bunch of hoverdiscs both mini & full size along with both kits and a couple-o'bombs. I can't thank Tom enough for his generosity and for getting me back in the air quickly after the sad demise of my HD. Thanks Tom

I intend to have a go at the mini rchoverdisc first just as soon as I get some pico sized servo's. In the mean time I'll be going over Greg McNair's thread for setup details here.

Ok, yeah I'm pining for my crashed RCHoverdisc but I thought I'd dust off the old x400 heli and give it a quick work out. I've not flown it for 6 months or so, so I did nothing spectacular....just flew around a bit to make sure I hadn't developed any heli killing nasty habits. I remembered quickly that concentration is required. You can't go looking away to swat flys - that results in carrying heli's home in a plastic bag. Also I quickly realised that I'd got used to a big 3 foot inflatable 'space hopper' which is a helluvalot easier to see and fly at distance than a 1/2 metre class heli...so chasing sheep was a no-no apart from the two that had strayed close to the kill dozers.

The trouble is with my heli and the main reason why I haven't been flying it is the battery is toast. Too hot to touch after just a few minutes with a 400dh motor and now even swelling. Thats not good at all.

I might switch back to my old Ark motor and drop to a pinion down to see how it handles that but after 50-odd flights of abuse its not looking well.

Anyway heres a quick video. The only good thing about this one is the lack of vibration. The camera is just stuck to the canopy with a few strips of double sided foam backed tape. Seemed to work well. Also near the end as the power fails you might also be able to see the flashing lights of a fire engine dealing with a roadside bush fire. Tried to sneak a decent view but my heli wasn't having it and I had to land before it plummeted.

At least it doesn't look to bad standing still with its Panzoa carbon frame, FG T-Rex canopy and black T-rex LG...but needs some money throwing at it to get it back performing well again.
