Hi Guys
I was wondering if any of you are still flying the Spanish design FIVE-JET? Its an excellent trainer model and the MW54 size turbine can be used in it. I use my home-built KJ-66,with full auto-start to power my one. I made a bigger wing for my one,to give it more wing area and it made a huge difference. The new wing is 400 mm longer than the original design. I am planning to build a bigger version of this model,for the P120 size motors.
Regards
Craig

A friend, also named Craig, has one currently damaged after a landing accident. He's currently building another. Both use the Wren MW 44, less engine, less fuel, less weight. They fly fine from our grass strip. - John.

Hi Dave
I bought this kit about 5 years ago from Jesus de Acros. He arranged for it,from the designer of the kit and sent it on to me. I havn`t been on their site for a very long time and can`t even remember how I came across it. If you use your search engine,type in "FIVE JET" and you will come across it. They have got a new one,called the "SIX JET". I`ll see if I can find their web page and then I will post it here.
When I bought my one,I only purchased the fuse,canopy and tail booms. I built the wing and stabilizer. The stabilizer was just a piece of 10mm balsa sheet,with the ends rounded off a little. I used the profile of the CURARE 60 pattern plane,to build the stab and it is fully symetrical. It generated more lift in the tail section. The drawings also show a built-up version of the tail booms. I kept the rudder servos inside the wing and used 1.5mm piano wire,to connect up the rudders. This kept the tail section light. The main undercarriage is made from 6mm marine aluminium and is very close to the duranium type undercarriages,which MK used to make or still make. I had to make steel jigs,to bend the aluminium plate to shape and then I cut out the "Lightening holes".Its very tough for a home-built undercarriage.
On my new model,I will use retracts and a 120 size motor.
Regards
Craig

Hi Craig,
i am now on my second 5 jet with MW54 14lbs thrust.
Fixed u/c for simplicity.
I have also fitted flaps and had a few flights and they seem quite effective.
You need to slow it down as it come,s in fast.
Been having fun with them for a few years.

I have had mine for four years now, and I love it!
I thought twin boom trainers were a thing of the past, but look at the success of
the Boomerangs (and they dont even look as good as the Fivejet :-)).
I think the Spanish guys could have made a lot more out of that kit.
MW54 sized engines are a perfect fit and you could mount a 50 oz Dubro tank right on CoG.
Mine is light built an weighs exactly 5kgs without fuel.

Hi Martin
I had speed brakes,which were fitted on top of the wing,but never had a chance to test them,because the model crashed on its maiden flight. The crash was caused by the gears on both of the aeleron servos,which stripped their teeth. I have thought of flaps for my bigger version,which I am going to build. The NACA design wing profile is good and this is why the model just wants to keep on going. I normally land it in a "dead stik" condition,especially if there is no wind.

Hello Lars
Thankyou for your photograph and I am glad that there is still a few of these models flying. Thanks for the link to their web site as well.

Hi Guys
Here are some photographs of my 1st FIVE-JET,which crashed on its maiden flight. I just had to replace the wing and also built a better turbine for it.

Hi Guys
The above photographs,are of my first jet model and I was so dissappointed,when it crashed on it maiden flight. The aeleron servos were called Eagle servos and they were not for jet model and I learnt this the hard way. At that time,there were very few jet models,here in S.A. and we all learned by the "trial and error" thing. I left that model in my Workshop,for about 2 years and then one day,I decided to get it going again. This time,I changed a few things and now its my "weekend flier". The engine was a home-built one,manual start and I used the first FADEC unit as the ECU.
