I hope you'll agree we have a nice and varied little collection of items here this month!
I had an interesting e-mail from Peter Miller, whose chum had bought a Robbe 'Charly' r/c model parachutist at an auction and needed some help and advice about setting him up. It was an unusual request which I couldn't answer, but I knew a man who could! Read all about it next month!
Trans-Atlantic Flight of an FAI legal r/c model
Record attempt planned for August 7th 2002
Latest news from Carl Layden
On club scene #53, Craig Trickett, President of St John's R/C Flyers, Newfoundland, Canada, gave us news of a planned world record flight of the Atlantic with an r/c plane. Here, Carl Layden, also a member of St Johns and one of the main organisers of the event from the Newfoundland end, gives us the latest news.
Some of you may ask,
"What's FAI legal?"
Setting up an external tank for a Cox PeeWee ·020
by Andrew Donatelli
found the engine to be quite reliable running on Norvel 25% fuel.
To set up an external tank
for the Pee Wee, first remove the original tank and drill a hole in the
side of it just large enough to fit a ½A fuel line.
Close encounters with an IFO
I actually think the IFO is going to be a really great flier - I just need to give myself a little more room for some "proper trimming" flights next time.
Next month, read about Tony's rather different model Halifax.
Futaba transmitters alert!
Gordon Cook, Chairman of Test Valley Model Flying Club, UK, alerts us to a weakness in the design of Futaba transmitters that could have cost him dear at the flying field recently. When Gordon ran through his pre-flight checks prior to rotating his pattern ship, he discovered that he had no rudder control in one direction and which then failed entirely, eventually tracking the problem down to a broken wire in his Futaba Field Force 8 transmitter.
is set up in Mode 1 and the problem was that there is a small circuit
board mounted at the base of the stick that actually moves back and forth
when the stick is used in the elevator sense - elevator and rudder control
being paired on the left-hand stick in Mode 1, as viewed from the operating
position. Wires from the board are connected back to the relevant pots
and the continued flexing of the wires to the rudder pot as the stick
has been used for elevator control caused fatigue in the wires to the
point of breaking. Gordon thinks that the reason why the rudder worked
in one direction only - for those last few movements that were witnessed
before total failure - was that in one direction the rudder wiring is
in compression and the other in tension.
Not much you can do about it, except to be aware of the possibility of this fault developing and if you have a transmitter that has been in fairly regular use over a period of three or four years, check it out!
Arising from this incident and from his own considerable experience and pedigree in model flying, Gordon has written a very thought-provoking piece on the general reliability of transmitters. Look out for it on the September issue of ModelFlight.
