AeroNutz News Letter 79a, Feb. 2002.                                 

Next Fun Fly is on Saturday 23rd Feb 2002. 5pm until 11pm, £8 per flier, fliers with models over 10g (weight of a pound coin) must be insured.  R/C planes must weigh less than 85g and be of scale appearance. Fishing pole, tables and chairs provided. Free parking, hall heating will be on.
 

E Pilot (Michael Henriksen) in Germany has made a 12” span Jigglet  with Z Tron, infra red, control system, using Dr Chris’s voltage booster so he can fly using one cell and a pager motor. Fuselage is 2mm-wall foam and wings are (European) 6mm-wall foam with a carbon stiffener laid into it. Total weight is a very handy 12g. There are now several one-cell planes about, a trend that will no doubt continue next year.

Rubber Power
Peter Frostick is making a Pink Mk10 Spitfire. It will be rubber powered with R/F control running from a capacitor, something well worth seeing when he gets it all sorted out, his last rubber power R/C plane was a Flea, which flew for 90 seconds!
Mark has sorted out his Ikara P51d and it looks really nice in the air. Needs lots of up elevator.
Barry has made some nice Depron sports machines, which could be used as park fliers too.
Big John has won a Gold Star on his report card for wearing out his Aeronutz Mk3 rubber motor winder/counter, that’s lot of wind ups!

Mark’s theory that young people are clever than olde people (otherwise we would still be living in caves) has so outraged Bernard (79 this year) that he has got a grant from Saga and set about building a R/C plane. The 35 MHz Hectegenarian, caused quiet a stir when he dropped rubber power and went electric - much like Bob Dylan before him. Mark will be checking the plane’s weigh to see if it is over the statutory 85g, in which case he will be banned along with all the other R/C fliers he has been moaning about for years. If you see Bernard launch one of his “bonce bashers” it might be wise to continue hiding under the table as he might have his left and right mixed up. Bernard is the one with the Saga baseball cap on backwards. Said model is a Depron flying boat with geared Kenway, five 50mA cells and rudder servo which means he will have something polite to do with his hands while his plane is flying

Andy has done some fine work with Muscle Wire, he started by making a simple throttle for his Co2 motor and has now moved onto consider elevator control.

Mark’s Mig 3 is in Coventry where it was flown by Graham Stanley at their last indoor event, said to be well received by the locals.

John had some nice flights from his first electric F/F machines. A two cells, direct drive, KP00 powered Depron sports machine designed by Bernard “Two Cells” Wright.

70 mA NiMH cells.
Peter Frostick is successfully powering his radio control systems from just one. Mark is going to use two and a geared KP00 with super efficient carbon prop to power a Spitfire, about 13” span and 21 grams using a 2mm Depron wing. The 70mA cells weigh 1g less than the 50mA NiCds but can't handle more than about 500mA.

Hello to the French and Belgian chaps who saw Mark’s infra red, two cells, Corsair being flown by new Aeronutz man - Philippe. Philippe was very pleased with it despite its performance being reduced because his charger will not correctly charge just two cells. He now has a new one and he is looking forward to getting up in the roof steels. However! The Corsair is direct drive and produces about 7g of thrust compared to the Mig’s geared 11g of thrust and longer flight time - whoopee!

New Vids. Andy is going to put the vids on a CD in mpg format so if anyone is interested in starting indoor flying or designing little remote control planes you can see them flying. The basic design details are on the web site too - just how easy can we make it!

MD2.  Mark has 60m2 of 2mm thick Depron.  It seems softer than previous batches so we can form airfoils easier, it is 60 per cent lighter than the 2.5mm thick Depron used for Mark’s last two cells Corsair. To make a wing just draw round a template, round off the LE and TE edges, form the airfoil, paint, cut into bits and glue back together forming the dihedral - quick, easy cheap! You can buy all sorts of sizes from Flitehook as both supplies came from the same importer.

Foam glue, alas Bison is no more, UHU Por and Czech versions exist but they are slower drying. We have asked the new EuroNutz to see if they can find a quick drying gooy glue.

AirVironment’s Matt has sent us some very interesting information on his planes. They are generally higher speed outdoor designs but very small non-the less. He has written a very nice article about this super little 9” span, balsa, P47. The article which should be out in the shops in a couple of months, covers wind tunnel testing, construction and flying with lots of nice pics.  The P47 uses five 50 mA NiCd cells and a Kenway direct drive, flies a over 25 mph - as you would expect! He has done some nice little data sheets of some of his planes, thanks to him for letting us use then here
 
Chris Stewart from RCS Techik (Falcon Kits) came along to test his new super scale balsa Vimy. Soon to be kited like the successful DH60, SE5, DH2 and Tiger Moth, what a pleasure to see his traditionally made balsa models again.

Good to see new indoor events springing up all over the place, Mark has been encouraging the Americans to get their indoor scene going.

There has been a lot of interest in one and two cells planes this month. Dr Chris has made some carbon fibre gearbox housings, which make it much easier to use pager motors.  Gordon is selling a few of his carbon fibre props, they are suitable for sub 25g gram planes with two cells and geared KP00 motors.

Dr Chris has been using a new DIY 27 MHz system. It is two channel and proportional, weighs the same as the Z Tron infra red system - which is very good. He has flown with 35 MHz systems without problems but it can’t be used with another 27 MHz. Chris says he is not planning to sell them, but it is another interesting development and another mile stone on the way to indoor Valhalla.

Carbon Prop. Developments.
Gordon has run a muck and made a two piece mould for a three-blade prop! Some fine development there, well done to him.  Mark has made a two blade mould. The female half is made from clear plastic so you can check and see what the C.F. is doing underneath it. Dr Chris has successfully made C.F. props by making the blades separately and then fixing them to a central hub. Carbon props are very important because we need a very thin prop so it spins easily which allows us to have a larger diameter, which is in its self more efficient. Our new WW2 fighters do not have undies, so they land on their prop, so the prop has to be a tough too. Mark is writing a data sheet on making making CF props, it has an 18 certificate as it involves detail descriptions of male / female parts, lubricants and barriers. It will be available soon, in a brown pager bag.

Mark and Philippe are tinkering with old R./C Tx’s, converting them to infra red control. This involves replacing the 5k Ohm pots with much larger value ones, not as simple as it sounds! More details later.

Graham has made a two cells CAP, I am not too sure what a CAP plane looks like but if it flies as well as his two cells IR SE5 at 11.75” span we will be as delighted as him.

Details of Rays new Delta and the other new remote control planes are now on the web site

Nice to see that Bob Selman is flying one of  Dr Chris’s, Z Tron, infra red, foam Jigglets, I think I am right in saying Bob is the only American fun flier making aviation with sub 25g planes?

Summer project - I wonder if we could get a 35 MHz, three channel, 25g, WW2 fighter flying at the August Bank Holiday Nationals?

Sergio from Z Tron  will be at the WRAM show with all his infra red control systems and Dr Chris's one cell Tiger Moth
