South Leicester AeroNutz

NL 57  Oct 2000
Next Aeronutz Fun Fly is on Sat. 21st Oct 2000, 5pm until 11pm at Parklands Leisure Centre Oadby, £7 per flier, bring a warm jumper, Tables and fishing rod supplied, All R/C fliers must be insured,

R/C Model Restrictions at Aeronutz Events,
All machines must be semi scale and weight less than 150g. All other machines are strickly banned, no excusses. If in doubt, ask before you travel . We are keen to help new folks get into indoor remote control but we are heading towards semi scale 25g models so its no good building 7 cell carbon stick machines.

Bernard's made a super little blue foam Yak 15, rubber powered I should stress as he is now a remote control flier too - he will have to sit on the RC side of the hall and get out of everone elses way!! He has also made a Cradinal, I thought the Pope makes those?!?!

Microflight Mag have nice looking little electric sea plane the Pond Baby - intereeting, we might continue with our swiming baths based Schnieder Trophy idea.
 

Now we have new light weight control equipment, the Aeronutz are considering reducing the flying weight of models at our Oadby events from 150g to 80g. Electric fliers are asked not to design machines that fly for more than four minutes, which with the 100 Ma NiMH is now easy peasy. With the new light and cheap IR control systems we would like to see fliers bring a couple of sub 40g single motor mono planes and a nice twin steer twin model each flying for 3 minutes - and some F/F planes too. We still think there will be more indoor fliers in future and so we can't have two planes being flown continuously for 8 minute flights. Our Two Cell Two Channel project is going well and we are encouraging new indoor fliers to start with these machines.

Two Channel Two Cells.
We are confident we can design and make the models (mono plane about 16" span flying weight 26g) we have the motor and gears sorted out (500mA @ 9g average thrust) and the IR control system is working from a 2.2v supply using our DC/DC converters. We are just sorting out how to control the rudder, muscle wire or coil actuator? Probably start with coils actuator as the MW is using huge amounts of power at the moment. Andrew controlled the motor on a three cell Kenway powered machine with the IRRXFA Rx at Nottingham and Bernard has the same system in one of his Depron two cell KP00 models ready for Sat 21st Oct.

Big Tango man - when M&S started indoor F/F flying way back .. it took their combined genius three months to get a plane to climb - now new fliers and son have produced a stretched Tango that cruised beautifully round under the beams - excellent start !

It seems that Rick Ruijsink’s wife is seriously ill and there is a good chance he will not be visiting us or for just a short stop on the way back to the ferry home. We hope all goes well for them both.

Barry has some had a model published in Model Flyer, a Russian Foxbat made from Depron with rubber powered looks nice, could be a good park flier as it would penetrate into any "wind"?

Nice to see some new indoor venues around the country

Jetcal, paper that can be printed on with an inkjet and produces a thin self-adhesive decal, the sort you wet and slide off.  <http://www.modeller.co.uk>

Simon's re-designed our web site too, nice new photos of Mark's Catalina, Andrew's Flycatchers, map to Parklands has been added to the new General page
 

Hello to the three families that stopped by at our last funfly , one being entranced by Ray's huge super slow flappy wing thing, don't just stand their launch something !

Steven Glass has some really nice F/F outdoor jets using ducted fans (see Flying Styro Corsair jet in Model Flyer) He is also interested in indoor models so we hope to see some fine machines from him,
Ray has bought a twin steer IR system and we think he has a twin ducted fan machine and a flying wing ready for 21st Oct - but it’s all bit secrete.

Mark's 29"  Catalina has had three blade props fitted and goes much better , some of Andrew’s photos of it are on the web site. It flies real slow - 1.8 oz/Sq. Ft and with a power to weight ratio of about 37%. It is infra red controlled and has no servos - steering is done by varying the thrust of the two motors, the same as Simon’s flying wing, Southampton, and err the other one. Steering on the Cat is adequate for missing the walls but not brilliant as the motors are running at almost pull power and twin steer system is better with about ½ to 3/4 throttle. If you are tempted try one at about 27” span. It is powered by two 50mA Ni Cds and KP00’ with std. orange pinions and a non standard servo gear, carbon prop shaft, three blade KP prop set to fine pitch - uses about 480mA per motor. The battery voltage is boosted up to 3.4v for the supply to the Rx using a Mk1 DC/DC converter. If goes without saying that its made of 2mm foam. Has a crew of three with the pilot modelled on our own president Joe who flew them when he was half Mark’s age.

Bernard is using IR control but just for controlling the motor. Rather than having plugs and sockets for charging and no switch he is using a switch but charging the cells via the metal U/C legs, be careful not to short the battery by connecting one leg to the other, leave the model discharged.

Mark's 4 cell Rumpler is proving tricky to trim just like the Albatross was, a proper R/C pilot would help too!!!

The new aeronutz rubber powered, free flight, Project 56 is going well, the latest sports a nice orange and brown stripy paint design, there will be a plan for it in the near future.

FliteHook have a luvvvly new small plastic prop, similar to the Ikara Butterfly one but 115mm Diameter. Mark has used one on our successful Jigglet design and it goes well. Buy a dozen !

Andrew is working on a counter rotating prop design for the KP00 motor!!  He has also added a coil actuator to his experimental Kenway powered Infra red controlled glider.

Mike has used a new cicruit to convert the output of a JMP 2.3g micro R/C Rx. It can now control a proportional coil actuator, making it very similar to the Rick Ruijsink system. The new new cicruit (digital to pulse converter) is from the USA - more details later
