To avoid unwanted flexibility of the plastic horns I make new ones from aluminum, and to avoid the servo meal gear tolerance, I changed the servo to a plastic gear servo.
The final weight of the all system is now 163.2 gram (134.2+29.0).
Best regards,
Isaac Najary

Hello
Today I flew with Isaac Najary, And I saw the Najarylyzer In action
At a time when the plane dive Isaac runs the air brakes . and have to see it to believe
The Plane diving vertically at a constant speed and slowly Like a parachute attached to his tail
Very impressive

Dives without any brake takes about 7 seconds.
Dives with the air-brake and the motor brake takes about 10 seconds – it is 43% longer then without any brake (10/7-1).
We did not film dives only with motor brake but I cam estimate that only with motor brake is somewhere in the middle.
Best regards,

I search this forum on "air brake" and found this thread. The finishing and all the machining technique is way more advanced than what I could do but I like the idea.
My Monolog 1.6m tends to land really hot. It doesn't bleed off speed. And at my club, I have to approach over 60-70' trees, have 400' to glide, and then a 400' grass runway. I see at least two planes a season go into the trees on approach because the pilot misgauged altitude or range so I always leave some safety room and then I almost always land way to fast.
The Monolog is a low end plane with parallel sides. I'm running through my head how I might be able to build something like this as all I'd need is a straight rod through the airframe. Maybe just monocoated balsa and a 3-5mm carbon rod and 12g servo would do it. Might make a fun project if I can just get my bench cleaned up enough to do some work.

Not to take away from Isaac's great creativity but, for L2T, another option is Spoilerons. Pushing the ailerons up 5 to 10 degrees to kill some lift and add drag once over the trees may be helpful. Most radios can handle this easily and what ever pitch mix that may be required to maintain glide. I have but don't use a three position switch with flaps for takeoff, center for flight and spoilers for landing.

I guess I might be hijacking this thread now. I read a tad about spoilerons and flapperons. I find spoilerons counter intuitive as planes use flaps to land. I did have flapperons on one of my light epp foamies. Didn't care for it much. The thing would land slow gosh darn slow withoutt flaps that flapperons were kinda stupid and flying that slow all I found they did was reduce aileron authority to almost nil.
I would have though flapperons is the way to go but I could program in spoilerons in about a minute. Then of course get three mistakes high, and play with them a bit.
But if I can finish to two projects on the bench now, I might play with the nararjilizer design just to see what it might do for the plane in general.

More seriously, I do know if I'm a good enough pilot to pull that off. I'd have to practice it at attitude to get a feel for it before trying it on final. One more thing to play with sometime.

Adjusted properly spoilerons are perfect for this application, sliding the plane for somebody that's starting competition might be very overwhelming with the added pressure of scoring landing point.....one may setup the plane badly on final if there's a strong crosswind/turbulence and getting much worse when he then try to recover....
Flaps all they do is increase lift at a reduce speed, which in this case you would just need to dive even more, don't think full scale putting a full size in a slide is much easier and pretty natural since your ass will (should feel) what your doing

Hey BG, welcome to the hijacked Najarlyzer thread. I saw your post on the RCG Monolog thread on the throttle->spoiler mix. I really want to try some of this stuff, I just have to wait for the rain to end.
