Frocester landing Many of our members do not like to fly at Frocester because of landing worries. The pessimists may like to read this article http://www.ebley.plus.com/frocester.htm The optimists should look at these movie clips Pegase8,wmv the ideal landing approach is 1.40 minutes into the clip although there is no landing until the end , notice how the model slows in the compression . The other also by Ian and shows landing a zagi and a 3 metre model . The landing is very safe as the model is nearly stationary, it is the approach that needs courage http://www.dursley.plus.com/videos/videoclips2/frocesterlandingapproach.wmv Please note, the brambles can cause minor damage to large film covered models Virus warning |

F3J, B or F moulded glider. Would consider one in repairable condition. The MSA need a new/second hand slot
timer. Do you have any
It would need to contain a microcontroller based timer circuit referenced to a quartz crystal, a large clear LCD display and a low level audio output for an external PA system. The user must be able to select from standard pre-programmed time slots of 8, 10, 12 and 15 minutes, and for warning tones to be output when the countdown periods reach 2 minutes to go, and then 10 seconds. In addition, the user needs to be able to program any time slot up to 59 minutes for other types of competition. All time settings should be shown on the LCD display and the current countdown figure. The system must run from a standard 12V automotive battery, making it ideal to transport and set up quickly at any location.
Regards, Nick Neve.
F3F racing Sunday Had a top 10 finish with 20 runners so can't complain really: not as rusty as I thought I'd be and am looking forward to competing in a few races this year. 1 9767.64 Mark Southall Sorry no pics: light was crap.Did get a sun tan though...?! Will probably be out in the week. Andy Freeman |

Tuesday at Frocester, 20 MPH till late afternoon when the wind went light but enough lift for Alan's copy of a Phase 6. This was very light and easy to fly in light lift. We had the usual argument, Alan wanted to put another 4oz in the nose and I thought 4oz should come out. Andy had a fly on his way home from work with a Nyx |
| Wednesday at Selsley, It can be annoying when the wind
keeps changing but today it went from the west slope to the north slope
and back to to west, just a short walk. A very warm day for the time of
year, where were all the scale fliers?
This Rutan Defiant passed overhead see http://en.wikipedia.org/wiki/Rutan_Defiant for details Thursday strong lift at Frocester but feeling cold in the strong breeze |

Friday a fresh westerly and not very warm

| The idea is to set a model up for its optimum performance
and make it nice to fly. Ailerons on a model like this need to go up a little more than down to get a nice roll. Flaps need coupling to the ailerons to get a good roll rate. Flaps and ailerons need to be lowered to allow the model to climb well. Elevator to flap coupling makes it turn tighter. Crow braking makes landing very easy, the flaps go down and the ailerons go up a little to avoid tip stalling , down elevators stops the pitch from altering and rudder coupling is switched in with the throttle stick , this helps with control and makes landing very easy Photo Crow braking deployed, with this amount of flap it will fly slow enough for me to catch it

Malvern auction, plenty of time to view the models,
rather too much while all the sale items were slowly entered into the
computer. When the auction finally started we had a detailed description
of a plethora of books, this seemed to go on for ever, most sold for a
£1. There were a few quality models and many thermal type models. The
Hawk looked good..
Adrian bought a Calypso Contest T and I bought a moulded HLG
. Doug sold his PSS Tigercat and John Parker bought a 60 slope soarer. The money
was settled very quickly but finished at 11.00PM too
late to get a pint. total sales £1100. |

Indoor Flying – 1st Att Having been over to Chosen Hill school a few weeks
ago to have a look at the indoor flying, I decided to give it a go. To
me, it seemed something like a Crash model (from Robotbirds) or a Mini
IFO would be a good model to start on. These are both small and light
models, which should work well in the small hall. The bigger &
heavier models just zoomed around “wall of death” style which looked
a bit hairy. So, having deep pockets, I decided to build my own
model. First things first, onto eBay to get some 3mm Depron. This was
duly ordered, only to find out 3 days later that Tim that had
bought a stack of Depron and was selling it at ¼ of the price I paid (Doh!). Next was the radio gear. My eyes fell upon my old
Piccolo helicopter gathering dust on a shelf. Five minutes later I had
stripped out the 3 servos, receiver & Phoenix 10 speed controller.
Now all I need is a motor and 2 cell Lipo pack. Back to eBay and a
brushless motor is winging my way for £9.50 from Hong Kong (RevolutionShop).
Then onto RCM Direct for the Lipo battery and some carbon strip. A couple of weeks later all the bits had arrived,
so time to break out the scalpel and glue. A Mini IFO shaped piece of
Depron was cut out, edged in carbon strip and various bits of radio
stuck to it. Model built, onto the flying! The longest part of the
construction was thinking up a name. I eventually came up with I-Ope. …As
in I ‘Ope it flies J

Over to Chosen Hill school on the 10th March,
let’s get it in the air. I connected everything up, waggled the
sticks, here goes…. Oh errr, the room looks awfully small now that
I’ve got a transmitter in my hand! Anyway, model on the ground, full
throttle and take off. Followed ½ second later by the I-Ope flopping
into a weird half loop and heading straight back at me. Then another ½
second later, a crash as I cut the throttle and it hit the floor.
Hmm….

So time to go home and build I-Ope 2. This will be
pretty much the same, but much stiffer (hopefully). I discovered that if
you gave it full throttle, it warped the LE of the wing and I got a lot
of down thrust ….not helpful J If you fancy a go, make sure
you build something LIGHT so you’ve got half a chance of flying it
slow enough so you can control it. A 2 cell LiPo is more than adequate
and something like a Shockflyer would be ok, as long as you keep it
light. Incidentally the photos are the “after” shots.
Don’t laugh at the big hole ripped out of the front after the last
crash, it’s not funny! .. Well it is really, but not as
funny as the bent prop and the slash in the wing where the prop stuck
through it after one “flight” Regards, Mike |
