Hi Guys,

Here's my latest toy . I call it the FFF . Fu##ing Fast Foamy ! It lives up to it's name ! I know it's been done before but not in my part of the world

The airframe is a Multiplex TwinJet meant for twin electric motors . Add one Lambert T32 Kolibri and you have maximum jet fun per pound ! The airframe weighs 2lb 15 oz wet and the engine is putting out close to 4 lbs at 242000 RPM . I have 400ml on board and that's good for about 6 minutes .

The engine is manually started with an air blower but a full autostart version is available . I don't see the need because it starts quite easily and runs really well .

During a rare break in the weather we got in a couple of test flights yesterday . Definitely a keeper !

Marc

Congratulations, and welcome to the Club of Most Fun Per Pound !!!!

PS. I definitely assume you do not mean Pound Sterling !


Nicolas.

Very Cool!
You guys across the lake sure know how to have fun

Hey Nicolas, The next time I come over the pond maybe we can get together and go flying...

I think I saw Alan C with Boomerang Jets fly one of those. I like your transmitter hand warmer deal where did you get that thing?

Andy

I'm just busy with completing my Colt V-glider with Kolibri again....

I like your FOD-screen, but also make an engine cowling from a bottle neck of a 500 ml water bottle... The diameter of the bottle is a bit larger, but don't worry, cut it through and use a little overlap...
It doesn't cost you anything, it doesn't add weight, but really looks better and moves the TwinJet even faster...

Most Fun Per Pound !

Rich,

Good idea ! If not, I guess we'll meet again at JetPower 2009 ??

Nicolas.

Ohhh man !!! That didn't take long for the thread to sink to new lows. Does look kind of fun though

To me, this looks more like Most Pounds Per Fun. [:@]

I loved that glider at Jetpower and would love to do that eventually . I'll just play with the TwinJet for now ! Regarding the FOD screen , where do you think I got the idea I used my little CNC mill to cut a ring and glued the strainer onto it . I don't think I'll do the cowl . If you look at my Twinjet , you'll see that I have my motor mounted lower and my elevons are made from balsa to be stiffer . I bet mine is even faster than your's now !![sm=punching.gif]

I got it quite a while ago . Can't remember . I just bought some thin gloves with rubber stickys on the finger tips . I'll try them today instead of the glove .

Here's my contender for the most fun per pound

Overall length: 62"
Weight: 102 lbs
Performance: Exceptional

Oh, and the Gripen is a lot of fun too!!! Regards, Jim

That's more like it !

Marc

Hi Marc,

Here's one more in my living room right now to make you drool. Just moulding a wheel caddie for it to avoid all these "overwhelmingly-enthousiastic-clubmates-who-wish-to-handlaunch-this-heavy-glider-after-too-many-beers-in-our-cantina" !

Nicolas.

FASTER ??? Impossible !!!

That's a good idea . Hand launching ,like building , is becoming a lost art ! I'm going to try launching the TJ myself today . Wish me luck !

Marc

Well to start with .... we already know that the white ones are faster than the blue ones . That and less drag due to the lower engine , it's no contest ![sm=devious.gif]

I agree with you, the elevons must be stiffened. Mine were done with one layer of glassfiber (110gr/SQM) top and bottom, with as little epoxy resin as possible.
I bet mine are lighter and stiffer than yours !!![sm=punching.gif]

I wish you luck ! I gave up after it became very obvious I needed badly such FOD screen !!! Two first attempts ended in the long summer grass and my turbine had ingested a lot of it. Shouldn't be difficult, as there are many vids on YouTube showing easy handlaunches ?... [&:]

Now I take it from the lazy side and use a catapult : http://nl.youtube.com/watch?v=qMNzONt1h9E

How much money goes into one of these Kolibri foam jets?
Scott

You mean in the Kolibri or in the foam ?


Prices of the non-foam parts are here : http://www.lambert-modellturbinen.de/html/english.html

But still, it is the Most Fun per Pound, either it be for the "Pound" the 'weight' or the 'money' !

Well ... I guess it 's also the most expensive per pound ! Off to go flying

Lucky you !

Ok, but who's dad can kick who's dad's ass LOL!!!!!!
