The next job was control horns which are completely different than the original, but this job was made easier with pre-cut slots. All were perfect except one set which were just slightly off, but nothing a dremel couldn't take care of. I don't have any pics of the actually step, but have pics showing the finished product with linkages and wires installed.

Hi guys, can any one tell me what power level you use on your landings? I seem to be keeping the power up to much on my landings, I was told to keep the power at about 1/3 throttle on landing and I keep land to fast and damaging my landing gear. Should I bring the throttle down to idle after I have turned on to my final approach with 45 degrees of flap? I am censored that I will stall it out if I do that, does any one know how well the Turbinator glide if I take all the power out after I turn on to final approach. What power level do you guys use on landing? Any input will be appreciated.

Mine has not flown yet but, with any airplane you have to experiment what it needs on final to make the runway the way you want it.
Flying my Boomerang on a no wind condition day I can throttle back to idle the moment it turns to the base leg, on a windy day I got to keep power to half till it turns final and my approaches are much shorter and higher to compensate for the head winds, if I fly the approach the same way as on a no wind condition day then I will have to drag the jet low and slow longer than I prefer, it is all about how you feel comfortable doing the landings.
I suggest to go up high and throttle back to a 1/4 throttle and fly the jet that way, if it doesn't hold altitude then allow it to descend doing circles over the runway, climb up high again and do the same thing again till you fell comfortable with it, that should help you get the feeling of it during slow flights, on windy day make a shorter approach, be prepare for go arounds.
I hope this helps, have fun, be safe

Thank you, Cars II. I will try that out on Friday, it looks lake we will have a 7mph wind. I will use about 1/4 throttle till I get close to the runway and take all of the power out.

If you feel comfortable cut the throttle around 25m before you get to the begining of the runway and keep descending, ground effect will give you a bit of extra lift when the jet is over the runway low and slow.
BE PREPARED !!! To go around early if you don't like the approach,.
No stress hey? Have fun and please report back

I've got an original 19lb Jet Central Rabbit in mine. Normal landing is turn upwind and drop the gear after the turn. If all three are down, I turn cross wind at about half runway, and pull the first notch of flap as soon as I'm straight on the down wind. I cut to idle then turn base, then final descending in the turns. Once on final I increase to 1/3 throttle and drop second notch of flaps. Once I know I've made the runway I pull the power back to idle and let the plane settle in.

This is what I have been doing when I set up for a, landing, I do a gear check fly by down the field, then do a turn on down wind leg at 1/2 throttle and drip the flaps at 20 degrees then reduce throttle to 1/3 and then do a descending turn on final approach and then when I am lined up with the runway I drop flaps to 45 degrees and I am still at 1/3 throttle witch should be about 9lb. of thrust, then when I am close to the runway start reducing throttle to idle and I am still coming in way to fast and running out of runway. I have a King Tech 120 that has 27lb of thrust and the engine is set up at a half expo, this is the default on this engine and even at 1/4 throttle the engine is putting out about 16 % of the engines thrust witch is about 7 lb. of thrust. I was told to keep the throttle at 1/3 power, I think this is way to much throttle with this engine, now this is my first jet and I am taking others peoples advice. I hope this gives you some insight on my landings. I hope I am not taking up to much of every ones time on here. I also would like to know what you guys are doing on a missed approach to do on your go around, do you take out all of your flap or do you just take out 1/2 of your flap. Do you power up first and then take out some or all of your flap.
Again, thanks guys.

T Perk...a friend of mine has the KT 120 in his Excalibur and it won’t slow down with that motor either. He has lowered the idle rpm by about 4K and turned out both rudders for more drag and it’s still a challenge. The plane will roll by itself even on his reduced idle. It’s too much motor for the turbinator. I have a Jetcat P70 in mine and it flys great but a 100 size motor would be perfect.

What Vincent said is correct, you have a much bigger engine than needed, since you are getting more residual thrust then the usual, then cut the throttle on the base turn and go from there.
For the go around, throttle first, for flaps and gear, you have choices, 1 leave all as is, fly the airplane to enter the pattern to land again but don't allow the jet to accelerate to much by reducing thrust as soon as you have gained altitude, 2 flaps up one notch and climb to pattern altitude, again don't allow the jet to accelerate, throttle back when the jet is at pattern altitude, 3 move everything up, flaps first gear second and throttle back.
What I do if I have to do a go around is, throttle to max thrust, fly the airplane as it gains altitude, once it has gain altitude then I reduce the throttle to about half and I bring her around for another landing, I don't touch the flaps or gear, the one thing I don't allow is for the jet to gain too much speed in that configuration, practice, practice, practice, don't be too concern about go arounds, they are your friends and save you from making a bad landing, make a flight all about emergencies and go arounds, to get familiar with the glide envelop of your jet.
Have fun.

One other way is to make a very tight down wind off the edge of the runway and then a sharpe turn on final and you are down. Sort of a carrier type landing. A long normal glide approach going to idle farther out will work too but that will take some getting used too. Be prepared to get on the throttle just in case you get a sinker and come up short. A head wind is always nice but in dead air my buddy has also killed the motor completely on final. Not a great way to land but that works too.
