Default 'Stinger' new composite sport jet (90mm)

Its back from the painters in a nice new shiny coat, although this is destined for Florida jets early next month to be flown by Ali Machinchy with a P20 turbine aboard this jet is totally optimised for 90mm EDF fan, fully composite, ducting, inlets sized to provide correct airflow. There is a trailing link gear set available for those interested or it can be bungee'd and belly landed. Its tough, flies super quick but slows right down to a crawl with no nasty habits.
Kit production starts in a few weeks time, more info and video can be found on:

Very sweet looking jet, was thinking about getting a Habu 32, but now, hmm

Interesting number comparison.

The Hacker a £215 motor and the Scorpion a £52 motor.

Scorpions are great motors imo, I’ve got four, never had an issue with any of them, had a few issues with Hackers in the past.

p.s. you should post this on RCgroups

Do you have any higher performance lipos to test these set ups as your at the limit at the mo, would be interesting to see the difference. Latest 65C 8s total voltage with may match your 9s 20C total voltage?

Hi, appreciate the feedback.
In the last few days a few of our new Stinger customers are going EDF, Stumax, Schub etc, we (Rich Chant the designer) and myself know this puppy will go with whatever you fancy putting in, wing tube is straight through so its tough.
My website is taking deposits on pre-orders, dont think too long ;-)

Joe ... The 100 quid is the booking deposit sum. If it were a mere 100 pounds, this baby will be the hottest item in RC history!

Default RE: 'Stinger' new composite sport jet (90mm)

the exact words on the webste are "Price shown is the PRE-ORDER deposit, the balance of the kit cost of £399 plus any shipping charges"

not that clear if total price is £399 or £499?

Marc, can you elaborate please?

Cheers
Alex

Its been a while and things have moved on, here's the update........

Following Ali Machinchy's flying session at FJ we decided to make a new plug, crazy yes, but with good reasons. Ali loved the way it flew but commented on the fact it could really do with being a 'little' bigger overall. Being bigger would just lock everything in and result in a smoother and better jet.

Well out came the cnc machine, new CAD drawings with changes to size, canopy opening etc... the resulting new plug was only 5% bigger but made quite a big difference.

We manufactured the new kit named Stinger v2 and got two completed airframes ready for Jetpower in September of this year. One was powered by a P20 Jetcat turbine, the second by Schuebeler's new HST51 12 blade fan.

Attached is a picture of the finished Stinger v2 in our FLASH colour scheme, one out of 7 schemes available. I have posted the video of one of the flights at Jetpower as well.

We have many orders for this little gem already and production is booked through to March 2012 as we speak, but as always we are open to more

You will spot the electric gear system we designed and manufacture specifically for the Stinger towards the end of the vid on the landing circuit, the gear, nose door and soon to added brakes are all electric so no need for air and all the clobber that comes with it!

The 'Glove'....

Now that we are shipping the Stinger kits abroad we had to sort out packaging and boxes etc, so using the CAD outline for the parting boards we made whilst doing the moulds it seemed like a neat idea to encase the fuselage in a foam frame, that way the whole fuselage is supported around its entire perimeter and should (not tested in transit yet!) help keep things undamaged.

The foam is 100mm thick and will sit in the middle of the box with foam blocks at 90 degrees to this panel extending to the box sides to keep everything in place. The notch cut in the top of the foam is for another box which is packed with wings, stabs and all the other parts needed to complete the kit.

I will wrap the fuselage in cling film to protect the paint finish and is thin enough not to bulk out the size and hence fit.

I got excited when it went together so had to post it as its not a way I have seen jet kits shipped, so was kinda pleased with the potential result. Naturally the client who's jet this is will I am sure let me know if it arrives safe!

Sorry its not strictly 'jet' related.....
