RE: Bob Cat Copy Falcon 120 Jet
 
Hi guys, going to order one myself. have a Artes Super Bee for it. Do you guys think this will be a good turbine for it? It's rated at 14lbs.

also, what would your best guess be the straight and level top speed would be with this turbine? Maybe 150?

Thanks


If we could see a few pics of the hardware install like tanks, plumbing, stuff like that.


thanks

Hi noahb
My mate has a super bee in his small mirage its about the the same wieght as the falcon.
And its very fast, i think the performance with your set up will be BALLISTIC.
Now ive set my54 up properley at 160,000 iam proberly getting up to the speeds you mention or at least it seems that way.
UPload pix later iam off too ,dare i say it a heli flyin.
regards Steve.

Guys,

As far as servos - can you please list the necessary servos needed fot the Falcon 120 ? a friend ordered one and wants to buy servos already, before he recieved the plane.

thanks.

Good servos are

For Rudders 2 Nr HS225 MG

For Elevator 2 Nr HS225 MG

For Ailerons......... 2 Nr any good 4 - 5 kg torque standard size servos

For Flaps.............. 2 Nr any good 4 - 5 kg torque standard size servos

For Steerable Nose wheel 1 Nr any good 3 - 5 kg servo

For Retract switch........... 1 Nr Any thing you want

How does that sound

anyone care to post some pics of the electronics install? Just wondering how you laid out everything for the turbine.

Hey Guys!!! Some fuel tank shots also please... also what size did you go with?
Thanks
MOJO[>:] Happy Flying Enjoy!!!

Well, I have yet to order my turbine but I was thinking the Artes super bee at 14lbs, however I have looked at the Falcon (22lbs) and I know the thrust is too much, but I can dial that down. however, I am wanting a turbine that will give me a larger choice of models.

Any input from you guys on the turbines?

The falcon weighs about 1.2 pounds heavier which may not be the best match for this jet...but with 22lbs of thrust, it does open up a whole lot more models to be able to fly.

however, the superbee is such a good engine and there is plenty of airplanes out there already.

thanks

The Falcon at 22lbs will be far too much for this plane IMO

RE: Bob Cat Copy Falcon 120 Jet
 
yeah I know. However, I will only be getting one turbine and would like to know from those who fly turbines alot what there idea is. I really don't ever think I will get a large jet, however I think the bee would do me just fine for most of the stuff I might fly. However, there are jets out there that I like where the rec. 18 lbs of thrust and the bee prob. would not do it justice.

On the falcon, I could always limit the rpm down to give me only 14 or so lbs of thrust.

then later, if I go to a diffrent jet, I could have the thrust.

However, the bee is really light and so trouble free.

I say use the power, but use it responsibly. The only limit should be your thumb's position. Use the appropriate throttle position when flying straight & level or descending. But when going straight up, warp speed Mr. Sulu!!!!! Beef up the structure to match.

noahb 08-05-2007 02:33 PM

RE: Bob Cat Copy Falcon 120 Jet
 
LOL. Here you about the verticle power.

I am torn between this Falcon 120 jet or a boomerang. The price tells me to go to the Falcon. But the boomer has more room to put stuff.

Would like to see some more videos of those that are flying theres already.


as for the turbine, I have yet to decide if the bee or the falcon.

I guess I better make up my mind sometime soon....

Hi noahb,

I believe either the Super Bee or MW54 Mk3 would be a perfect match for the Nitro Falcon. The MW S/S at 18lbf plus would probably rip the wings off the plane if you ran it at full rpm. After all, the plane is designed only for nitro engines.
The Jet Central Falcon IMO is a complete mismatch to this plane. Yes you can dial the thrust down but you can’t dial down the weight and physical size!

I’d go with the MW S/S, dialled down to 14lbf, if you have future plans for larger planes AND want to fly the Nitro Falcon first.

Otherwise the Super Bee or MW54 fit the bill.

HTH
Kind regards,
Eric

RE: Bob Cat Copy Falcon 120 Jet
 
I agree that the weight of the Falcon is excessive, but if you are certain to beef the airframe up, and don't mind the higher wing loading and wear & tear on the gear, go for it!

noahb 08-05-2007 03:52 PM

RE: Bob Cat Copy Falcon 120 Jet
 
Yeah, I know the falcon is too heavy, even thou it's light for it's size.

I will most likely end up with the bee. I have nothing bad to say about Wrens. Great turbines. However, the Artes Bee runs great, is very light and has a lifetime warrenty all for $2495. Not too bad.

I had considered the Wrens, but after looking at the Artes and reading about how much people liked them and the service...I will stay with Artes turbine. I do like the MK 54 SS. What a great turbine....

Don't want to hijack the thread... but I wondering if you can use a Throttle to throttle mix to limit the signal to the receiver in order to mimic the dial down on the turbine. You can use the retract switch so that you have full power for takeoff and aborts. With the retract up, the signal will limit the turbine RPM to whatever value you select, effectively dialing it down.

RE: Bob Cat Copy Falcon 120 Jet
 
I don't see why not. It would be the same as holding the throttle stick say at half way.

Edgar, sounds like a nice idea ! good call.

You guys using MINI servos (Hitec 225) on the elevator ?? why not 2 full size servos ?

noahb 08-05-2007 08:43 PM

RE: Bob Cat Copy Falcon 120 Jet
 
hey guys, the few that have there turbines in, can we get some more pics?

Pics of the fuel system, electronic install, turbine electonics too.


Thanks

oh, any more videos would be cool too.

All,
If you can go turbine, go with Wrens MW54SS (18 lbs), Artese Falcon (22 lbs),
Jetcat P80 or P70. Use batteries in nose to ballance, the wings are not going
to fly off if you fly reasonable (it is not a Bandit). The stability of this plane
is unbilievable (sp). I lost an engine after taking off today with full 85 oz
of fuel, could not make the runway so landed in the grass, gear up and
the plane was solid in turns (no power) and glided easy (no bad habbits).

Hello !

I have bought myself a Falcon 120 Here in Norway, and are planning to put on a os 1.60 on it...!!! What prop are you guys recomend me to use...???

The prepared cut outs are too small for standard servos the HS225 fit perfectly and have enough power so why make life difficult... Of course you could do what many do when they build an artf which is some or all of the following lol

1) Throw away the hardware on the grounds it is crap
2) Strip off the covering cos you dont like it
3) Fully sheet the whole plane cos you are going to overpower it
4) Make it so heavy by over powering it that it needs better landing gear which of course makes it heavier still which means you need more power.
5) Spend loads on top quality servos that are not needed
6) Make sure that all your servos are digital so you need a bigger battery and hence the weight goes up again

After doing all this you could just decided that you have bought an ARTF and trust it and use sensible equipment and the correct power for the plane..................... Still each to their own
