settings using FALCON 120
Hello
I am looking for the settings you have made on your FALCON 120 -
Can you give me your settings using for the servos Rudder, elevator, and spoiler (R &L) ?....
it is for a Kingtech 100G
I think start editing and enhancing early 2014 to fly in late 2014 - I started to buy major equipment..........
thank's

Refer to the Falcon 120 instruction manual. The recommended throws and CG are an excellent place to start. The only one you need to change is the flap setting. You'll need about 45 degrees (with 1/8" down elevator compensation) to slow it down for landings.
See if you can get your money back for the powerbox. There's absolutely no need for one in a Falcon 120. Also I'd be concerned about the reliability of those Chinese electric retracts. Use a separate battery for them in case they jam.

Thank's joeflyer
It is however recommended to use a power box on réactor jet ..but it well be using on my Pantera and Scorpion AD ....
I can use the Electron (40-EVO) or Robart (635 -639 - pneumatic ) retract that i have for the FALCON but it seem's too heavy - For years I use landing gear TURNIGY or RC LANDER (métal) and never had big problems..

The only planes, jets or otherwise, that need a powerbox are the very large ones with a lot of high current servos. I sure the Pantera doesn't need one and probably not the Scorpion. Robart 635's are way to big and heavy for a Falcon. I have Robart 550's on mine and they've held up fine for over 200 flights so far.
That being said you should use the equipment that you are comfortable with. The Falcon is a great, easy to fly plane. I have 5 turbine jets (none with powerboxes) and the Falcon remains my favorite every day flier.

as noted from joeflyer. you can also read page 126 (or 127) of this thread.
I'm using a Spectrum DX8 - I use 45% expo on Aileron, Elevator & Rudder .. I use a separate nose wheel servo on Aux 3 (and use the knob on top of the radio for fine trim of nose wheel), mixed from the Rudder. I use the recommended throws on Dual Rate Position 1 - I have "a little less" throw on pos 0 & "a little more" throw on pos 2.
I haven't used the "0" or "2" rates yet - have plenty of authority and docility as well.
I'm using a Wren 70 and its more power than I'll ever need for Falcon 120.
You may want to "dial down" that K-100G - it's a beast - I use one on my Boomer Sprint - what a rocket motor it really is.
Last but not least, these F120s ARF are notorious for the wing tube being about 1/2 short (mine was)- make sure the tube reaches all the way in the wings ...
Just take the very well spent time reading all the pages in this thread!!! and do all the mods your little voice tells you to do.

Hey Guys,
Is the Navy Cat the same thing as the Falcon 120? I notice they offer the NavyCat with carbonfiber reinforcement version and the pre-formed tank for a turbine setup.
Thanks,
Mike

Hello Mike,
Ken at KMRC Jets has a mould/mold? almost ready.
http://www.kingtechturbinesaustralia.com.au
I will be getting a couple when ready.
Please let me know if you find a source for the cockpit tub.

hi all have a mould for the cockpit tub and canopy. will be pulling some asap
all falcons came from fly model no matter what any one ever said that's where
they have been made. navy cats are carbon reinforced V3 falcons much stronger
than all earlier versions and more expensive. I import them into Australia. we also
have the blown plastic tanks $35.00 aud. can be sent any where in the world but
freight is not cheap

Thank you guys for all the good info. Ken I was pretty sure they all came from the same factory. How do you like the Navy Cat V3? From my research it looks real solid and no to little modification needed for turbine flight? But it does cost a little more.

hi mike
the V3 carbon falcons (navy cats) are much stronger and better built. the hardware package is also very good
I think these can now be called a jet model compared to what the earlier models were. by that I mean next to no
modification needed. I believe that henry no longer sells them due to a difference of opinion with fly model. in the
UK modelbau UK sells them as kestrels I don't know who in the states is selling them now.

Hello Mike,
I read your last post just now after returning from flying my Falcon at my local model field. The field is a short mown grass strip (www.larcs.com.au) and my Falcon has no problem with it at all.
Takeoff run is about 30m at full throttle from the K80 and landings only a little more. Today I slowed to a standstill into a 10 knot headwind with full flap deployed. Nose up attitude and a gentle rate of descent. Ailerons were responsive with no tendency to drop a wing. I have forced a full stall with resulting wing drop by assuming an excessive nose up attitude, idle rpm, no flaps and plenty of recovery height. The falcon dropped a wing, I let the nose drop and applied full throttle command, it accelerated quickly and recovered to level flight just as the rpm came up. Loss of height was about 80' so a full stall on the landing approach would be fatal but I really had to abuse the model to get it into a full stall. when landing I usually lower gear and flaps (flaps are as per factory setup and lower to about 45 degrees) on downwind, throttle to idle halfway through base leg turn onto final and assume about 10 degrees of nose up. This usually gives me a gentle descent with plenty of elevator authority left for flare.
I hope this info is useful.
Regards
Col

KMRC, Let me know when Navy Cat V3s are available.
The Fly Model Falcon 120 is (maybe "was" bc I' haven't seen them available any more for quite some time) a good cheap Chinese knock off model, provided you did due diligence doing all the mods req'd (LOTS if time spent doing so).
Now, I'd rather see something more ready/refined as a model "intended" to be a jet.
(PS CARF and others want way too much money for theirs)

Hello Mike,
My Falcon is a version 1 (single set of wing bolts) with ver 2(?) sheeted wings so I don't keep full throttle on for too long. I have replaced the thin wall ver 1 wing tube with thick wall ali tube cut to the right length.
(the correct metric size is easy to find here) I would estimate that the lower end of the speed range would be similar to a G26 powered, 72" span ARF warbird, say 10mph safe landing speed while the top end is a mystery. I would estimate my normal flying speed (about 1/2 throttle with the linear setting) to be in the region of 60mph. Before I would try an extended full throttle excursion I would buy one of Ken's Ver 3 Falcons and use top quality hardware capable of handling high speeds. Thrust to weight ratio with a full tank is about 1:1 and the Falcon is actually quite slippery so I would guess that it would effortlessly exceed 100mph.
Perhaps Ken from KMRC jets has feedback from ver 3 owners about top speeds?
If you decide to get one Mike you will enjoy flying it.
