Other than the Sky Scooter... of course.

Which of their extinct kits do you most wish you could get your grubby mits on?

Do you harbor any hope of a re-release?

Smokescreen38,

what a dangerous thread you have started here. Since reading it first time a few months ago, I have managed the locate and purchase the wonderful Sonic Liner (which I had never heard of before), and now the TwinJet



Like the Sonic Liner, I will build and fly the TwinJet. Probably with modest power 2122mm outrunners and counter rotating props. As far as I can see, the wing profile of the TwinJet is designed for more lift / lower speed than the FunJet...

EDIT: I read somewhere that the recommended CoG point is at bit too far aft for most pilots liking. Would 1 cm further forward be better? THX

I stumbled over this nice, old video when searching for CoG info:

TWINJET MULTIPLEX DIRECTORSCUT (1 min 11 sec)

this one is mine convert into a monojet after i crashed it . im looking for another one since this one is no longer considered a twinjet .
.

OOOooh, I like red
What did you use?
Why all that reflex in the photo?
I've had blue TJ's (Blue Shark?) but never a white one.Was there a planform change/upgrade with the white one?

No, the blue and the white versions came out the same time and the only difference to the former gray/green/blueish version was the color of the material used.

Thanks Jurgen

P.S. Though I think the TE could stand some straightening out.

Most definitely!

the reason it looks like it has alot of reflex is because it doesnt have any control horns/rod or servos installled . so it just stood up like that in the photo . once i installed back the electronics i will massage the reflex to be straigt. as for paint . i just used miniwax. over the stock gray .then i painted it and and put another coat of miniwax .
i want a white one so i can do a different paint scheme

That's what we were referring to, the strong reflex of the elevons, not the fact that they were in "full up position".

I was advised to heat up my elevons and flatten them out when I bought my Twinjet...but I was pretty sure that if I did this, the plane would require some reflex in the trim anyway as most delta configuration planes do, so it would be a wasted effort. I opted to leave mine stock, balance at the reccommended CG points and it flies perfectly! It has a slight tendency to rise with throttle but nothing that you can't easily compensate for.

You might be able to save a small amount of drag by flattening them out but unless you're going for a speed record, I suggest leaving them alone. This is a fairly draggy airframe regardless.

mine climbs with throttle down . i had the ship trimmed for hi speed . and it would track very nicely once i let go of the throttle it would climb slightly .who knows i may just keep the reflex on its built that way for a reason . and as you stated most "if not all delta wings fly with at least 5mm flex on the elevons .

this is a nice video of the twin jet .

My TJ flew ballistic (read that vertical) with slight up input.Full down could barely keep it level.Yes,there was carnage.
I suspected thrust angle & reflex so I flattened the reflexed elevon and re-mounted the motors to adj. the thrust angle (using short lengths of tubing for visual reference) to parallel with the chord line.
Flew a dream afterwards.
In the early days after the TJ's release there was a couple vids that blew me away.This is from those vids!
One was a fellow flying along side or in front of a boat as it cruised a waterway.about 5-7 min long IIRC.I would guesstimate 5-15 mph speeds.All caught on camera from behind the pilot.Right up to the landing (or catch?) in the boat.
The there was the vid flying around a fountain,The pond,IIRC was a large circle in & above ground maybe.The singular fountain streamed about 40' in the air around 10-20 degrees from vertical forming a pleasant arc.This TJ pilot fly around the fountain,through the arc and thru the water stream! It was Great!. Alas,all lost on a HDD far far away.

Those videos were from RCG user "henke" from Sweden. He is still active here.

I keep hearing that you can still buy a Microjet... is that right? Are there any suppliers in North America?

I'd love to buy one and do a light weight set up.
