December 2000.

Merry Christmas to our reader,
You are invited to our New Indoor Winter Expo and fun fly on Saturday 30th December at Parklands Leisure Centre Oadby, South Leicester 5pm until 11pm. £7 per flier/family. Fliers of machine over 10g must be insured (£1 coin weighs 9.5g) Remote control fliers can fly at anytime but their machines must weigh less than 85g and be of scale appearance - so no stick planes please, if you are in doubt please ask before travelling. FliteHook will be coming along, Mark will bring along his IR Catalina, Ray and Mark will have three or four Two cell, Two channel IR planes including Mark's new 13" span Vulcan prototype, plus all the usual free flight machines. Indoor Thermals - As its now a little colder you are advised to bring a warm coat as the heating will be off.  Tables and fishing rod supplied.

The view from here
We should have the two cell infra red control planes all sorted out by the end of December. We will be able to fly twins by varying the thrust or fly single motor machines with motor and rudder control, all controls being proportional. Then we can start building some more adventurous planes - jets, mini bipes, airliners, sea planes, canards - the usual sort of stuff!  Our Nov. event was notable for the lack of R/C machines, only about 5 were flown, all of them flew very well and looked nice as models and looked good in the air. Most of our indoor R/C builders now have the smaller and cheaper infra red system. This system can only allow one machine to be flown at one time. This will not be a problem if we all use two 50mA Ni Cd cells and fly for about three minutes. The IR system is very cheap so we can have three motor/rudder planes and one twin motor steering machine and a box full of F/F rubber designs. If you break a two cell two channel plane, just fly another, and fix it at home.

If we swap one of the parts on our new DC/DC voltage booster we can power the IR control system from one cell, I.E. 1v to 1.4v supply. We could then fly Co2 or rubber powered models using proportional rudder only. Mark and Flitehook are working on a joint project to try a rubber powered Hangar Rat with proportional rudder control. We might be able replace the 50mA re-chargeable battery and use a watch battery to reduce the weight, but it can't be recharged.
Graham has developed a combined infra red Rx and DC/DC voltage booster. They are on a special extra thin circuit board that measures 15mm x 15mm.
He has also figured out that swapping the IRRXFA's 4.7uF capacitor for a 33 uF one and adding 10 uF caps/100 Ohm resistors to the sensors smooths the output.

There will be two new indoor fun fly events next year, one in Coventry and one in Cambridge good luck to them - more details later.

Ray has made an A10 Thunderbolt remote control, twin ducted fan which is flying very well,.
While John has a really nice F/F rubber Gladiator in camouflage.

The current issue of Model Flyer (Jan 2001) has lots of interesting articles in it. One is about our October fun fly with photos of Mark's Catalina twin steering machine, Ray's big rubber powered flapper, couple of Geoff's RC jobs and Andrew's Flycatcher R/C foam model.  F/F twin Beagle by Andrew and a couple of youngsters explaining to Bernard how to trim one of his 496 Depron 25g KP00 powered planes. There is also a piece on building a Hangar Rat and an interesting article on how to make your own simple R/C Rx. Rick Ruijsink's trip to our fun fly in October stimulated an article on his models and Micro R/C system too. Dr Chris's mini IR Flea was in there too but he was called Geoff. - I been called worse things!
Peter Frostick and Eric Hook have produced their own two cell, two channel Depron machines based on one of Bernard's 25g F/F jobs, only it has three cells and weighs 30g! - someone could be killed !!

Stockholm's model club had a talk on indoor planes and samples of 2mm where given out along with Aeronutz model designs.

Simon has bought a digital camera. The new high tech snapper will be used to quickly and cheaply upload photos onto our web site. It is easier to alter or edit the digital photos electronically but it can't sort out chopped off heads or planes out of the picture.

Flitehook has a bigger tub of Bison Clear Adhesive  for about £2.50, useful if you are doing a big project or maybe even some DIY ( DIY! who does that)

America's only Aeronut Paul in Detroit has made a new Albatross fuselage following a major crash and is working on a 2mm foam Camel, He has just won a No Cal competition with a nice ME109 wubber power stick and tissue and is looking into converting it to a two cell, two channel infra red controlled machine - nice idea, if it's not too big.
Andrew's twin turbo power up grade, if you have a twin turbo system you can upgrade the power it can handle using Andrew's new circuit diagram, emial for more details.
Aeromodeller, have some nice photos of the F/F Jetex models flown by Peter Smart, including a Vulcan and Gnat as mentioned in last months AN News letter. It goes without says they are perfect in very detail!
Some of next years dates as now on our web site but not all as Parklands are not too quick with the confirmation letter ....
