Dear Ken, 

You bought some carbon fibre from me some time ago on ebay. As you are probably aware ebay take quite a slice of value of anything sold and I would rather you were able to pay less for the carbon fibre than make ebay richer. 

It was always my intention to build up a modest clientele to pass on my surplus carbon fibre to, without involving ebay and as such I am writing to you directly to let you know what I have available so you can get your tow at the best possible rates.

I have also been writing some articles about carbon fibre and about some of the interesting ways people have been using it that I will be sending out over the next few months to give people ideas about how to make super light carbon reinforcement, cheap and easy ways of controlling resin content and generally how to get aerospace results without a million pound budget.  I have attached an introduction to carbon fibre, which I hope will contain some information you will find interesting. Sadly I am still too busy to be setting up a website for it all but I am still committed to enabling people like yourself access good quality materials in small quantities. 

Obviously I recognise that although you have bought some carbon from me, you don’t necessarily want to have loads of emails from me. This is a personal email, so there is not an automatic link to unsubscribe, but you can drop me a quick response to say you are feeling harassed by being contacted and I won’t contact you again.

As always I am making materials available that I use myself. I currently have 4 types of reinforcement fibre available and I have summarised these in a table below. 

Manufacturer

Fibre name

5670

276

Hexel

IM9

Intermediate modulus carbon

6140

304

Tejin Industries

Twaron 2200

High modulus para aramid

6K

3176

108

 In a nutshell the Zoltec fibre, is a high strength fibre being offered at a low cost in 100g spools. It has 10X the cross sectional area of IM9 so you get a lot of carbon for your money. It has physical characteristics in-line with 99% of all carbon produced. You can split the tow to make thinner bundles as it is not twisted/ 

The IM7 and IM9 are speciality fibres that are considerably stronger than high strength fibres and also considerably stiffer too. As a balance of strength and stiffness, these fibres are some of the highest performing fibres available. IM7 is an aerospace quality fibre and spreads well to make very light coverings (35gsm unidirectional) as it has a very light size. IM9 is made to an industrial standard but was until relatively recently one of the strongest commercially available fibres. 

Twaron 2200 is a fibre that is very similar to Kevlar 149, which was developed to make the new generation ballistics vest. A very light weight fibre, with excellent abrasion, shock, electrical and heat resistance. One of the handy things about para aramids is that they are lighter, stronger and less prone to fatigue than glass fibres but completely transparent to radio waves and microwaves, unlike carbon, which opaque to these signals. If you want abrasion resistance or strength in areas near your radio receiver aerial, this could well be the material you want. Specification sheets are available for any of the fibres. 

Prices are as follows: 

Zoltec Panex 33 100g spool

 

£8.00

 

Hexel IM9 12K

20M

£4.90

50M

£9.00

Twaron 2200 100M

£6.50

 Add-ons

I have called these ‘add-ons’ as they are zero profit items for me. If you buy any of the above fibres you can add these items.  It will be £2.70 to post these items because they are bulky. I am not keen to sell them as items on their own.

Micro-fibres (cotton) (50g)

£3.50

Micro-light filler  (10g)

£3.50

Laminating resin (130g net) choice of hardener speeds

£5.50

Peel ply (Per Metre Square)

£3.00

 Cotton micro-fibres are generally used with epoxy resin to make a structural bonding paste (bog) especially for bonding wood using epoxy fillet joints but it can be added to other resins to make a structural material. 

Microlight filler is a very low density additive to make a super light filling paste that is easy to sand. It would also be useful for low weight low strength items.

Epoxy laminating resin. This is a 130g pack of resin that has 4 hardener speeds from extra fast to extra slow. A great general purpose ambient cure resin, which is less toxic than WEST or SP resins. I made this available primarily for the rolls of £35 intermediate modulus fibre and 100g spools of Panex 33. 

Postage is always at cost. Tow up to 100M is £0.85 anything over that and less than 750g in weight is £2.70. The Zoltec Panex 33 100g spools are £2.70 but you could get other materials sent as well. All my stuff is sent first class and usually on the same day. You will always get an email to confirm dispatch. 

Payment by paypal or direct bank transfer. 

If you place an order by 18th August you will get an additional 10M spool of IM9 free of charge.

 As always I am available to answer carbon fibre related questions via email and will send pictures of products or data sheets as required.

 Kind regards
Jon Evans

I keep loosing my keys and bought a locator system - works great

I just bought two of the small radio beacons but it will work with 4.

They would be good for tracking down a lost model model

Slope Flying & flat field

 Monday

I flew  my Shadow on Minch there was some strong lift
Tuesday
Light lift at Frocester, Tony flew his Speedo

Wednesday
I flew HLG on Minch and did not do well, I was launching 3/4 power to 80 feet and failing to find much lift, best flight only 3 minutes.

The Blaster 2 should launch to 150ft +

Conditions: wind 5 mph and overcast 

Afternoon at Selsley

Very weak lift early afternoon, my supra would not stay up mid afternoon. About 4.00pm the slope lift came back

I flew Adam's TopSky Viper and liked it, I am not getting a good launch, perhaps I am not putting enough weight behind it

I went to Minch with the idea of beating Adam's 12 minutes with an HLG and failed

best flight only 6 minutes

 Friday  

Took the Topsky Viper 2 DLG into the back field behind my house. Found a massive thermal at about 50ft. God know how high it went but thought I'd lost the plane on several occasions over the river!! Managed to get her down only to find another thermal up wind.

Final time: 14 minutes 22 seconds!!! Whoop
Adam

Too good for me, started with a 4 minute flight, but  failed to keep it up, common problem at my age

Fun Fly at the Nationals By James Gordon

 

When some people think of the B.M.F.A National Championships, they think of the country's elite competitors, seriously competing with expensive, state of the art models!

But, while this is the case with some events, there is one event that attracts flyers from the elite, all the way through to the average club flyer. This event is the Fun Fly. 

Fun Fly was conceived at club level all over the country in the 1960's and in 1985, the BMFA Mid-West area, headed by Robin Jones, launched a national event that became an integral part of the August Nationals and has been going strong ever since. Robin worked extremely hard over the years in support of the Fun Fly and with his team, made

this one of the most enjoyable events at the Nats. The new team, now in our fifth year, is mainly made up of members of the Caterham & District Model Flying Club, with contest directors being myself and Nick Lester. Both of us have competed in the event for many years and we too, feel very strongly that the Fun Fly continues to grow and goes from strength to strength. 

So what is Fun Fly? Basically, at club level, a fun fly competition can be pretty much anything as long as it's simple and fun! I belong to the Caterham and Croydon clubs, bothof which have monthly fun fly competitions ranging from limbo, touch and go's or spot landing events, through to slightly sillier events like water carrying, balloon bursting

or even doughnut dropping! All these events are designed to entertain, both the pilots and the spectators.  They can also improve pilot skills and confidence and they certainly add lots of fun to any club! The other thing about fun fly events is that they are all scored against the clock. There are no judges deciding how much they liked your flight – your

score at the end of the time is what you get - simple as that!

 The models, too, can be very basic. At club level and indeed at the Nationals, most people use well proven designs such as the Limbo Dancer, Avicraft Frantic, Western Cougar, YT Magic or the Evolution Fusion. All of these models have the benefit of being relatively cheap, quick to assemble and easy to fly. But with the right set up, then virtually anything is possible from the transmitter sticks!

 In the Nationals, we also like to encourage flyers to modify existing models or even design their own. Over the years, we have seen some wonderfully ingenious designs that have been incredibly successful and indeed, we are now looking at awarding a prize to encourage and reward such design flair. This, then brings another element to the competition,

for the model can't be just good at one event, it needs to be good at four or five very different events, so not only are the pilot skills being tested, so is the design of the model! 

So, let me now briefly run through what the Nationals competition is all about. Basically, anyone with a BMFA 'B' certificate can enter whatever your skills at fun fly. The event is designed to introduce the average club flyer into competition flying, thus boosting confidence and skill levels. Many well known national and international pilots started in fun fly and have gone on to huge success. 

The event is split into two classes. Class 1 is for the experts, where some of the piloting skills have to be seen to be believed and class 2 for anyone with a 'B' certificate who enjoys

a laid back approach to competition flying. There is, by the way, nothing to stop you entering both classes! 

Class 1 models are basically unlimited, whereas class 2 models are limited on engine size or electric motor, with no tuned exhausts and no coupling (mixing) of control surfaces.

This is designed to keep the models to similar performance and keep them affordable to everyone. 

Now, to the competitions themselves. Both classes include a Longest Glide task that requires the pilot to stay in the air for as long as possible, following a 20 second climb.

Also included is a Limbo competition that is won by the pilot that completes the most passes under the limbo gate as possible in two minutes. A Touch and Go task is also included in both classes, where the pilot completes as many touch and go's as possible in a large square, again in two minutes. 

Class 1 only has a Triple Thrash task, that requires the pilot to complete three touch and go's, three loops, three rolls and another touch and go in the fastest time, where

class 2 has a Spins and Spot task where pilots perform as many spins as possible on the way down after a 30 second climb, then perform a spot landing for added points. 

During the last few years, we have also added a mystery round for each class which is drawn at random at the start of the weekend. These events include Dead stick aerobatics,

Touch & Go Bang, Water Carrying and Doughnut Dropping! New for this year to also join the mystery rounds are Roop and Blackjack. 

Well, I hope that's wetted your appetite for the Nationals Fun Fly. We are certainly great believers in this event, as we think the Nationals needs at least one low key event

where anyone can come along and have the experience of competing on a very low budget and have a whole load of fun along the way. It also shows the public the lighter side

of R/C flying, which can only be a good thing and it is also great fun to watch!! 

So, go on, fill out the entry form in the June issue of the BMFA News and give it a go - I'll guarantee a fun packed and entertaining weekend! Copies of this year's rules are available

from the B.M.F.A office or from me at the following email address: 

wlmailhtml:/mc/compose?to=jamesrrg@hotmail.com 

We both look forward to seeing you in August, either competing or just come to the line and say hello - maybe it will inspire you to give it a go next year. 

Happy Fun Flying! 

James Gordon.
