Century Hawk - Falcon - Raven - Predator > Raven vs. Falcon

People have been saying good things about the falcon SE V2.

Is the primary difference between this and the Raven 50, that the Raven is CCPM??

Raven

Trevorz,
Yes the "primary" difference is CCPM. So, most of the differences surround the radio tray and servo placement.

Personally, I like CCPM but did not like the method that Century mounted the servos. Looks like somebody took a plate of aluminum and made a quickie bracket to mount the servos under the swash. To me it just looked "cheap" but, I bet that it is an EXCELLENT performer.

I think the new Predator 60 is going to be a CCPM bird ase well so we all might as well get used to it. Just think how many of the new release helis out there have been CCPM helis.
Venture
Caliber
Voyager
Raven
and I think I am forgetting some.

Maybe someone with a Raven will chime in.

CCPM

I already own two Kalt Mercury (46 and 60) CCPM heli's and the CCPM is excellent!

Provides much crisper response as you have 3 servos working on the swashplate instead of one. Only problem can be in matching the servos and you tend to take out servo gears more easily in a crash (at least with the direct to swashplate type arrangements).

CCPM

Yeah I agree. I have had a Vigor CS, Venture, and Fury. All use 120 degree CCPM.

Of the three I REALLY liked the arangement of theVenture. If you are gonna do CCPM might as well make it go through as few links as possible. Yes, they can stip servos but I think it is well worth it.

As far as interaction goes today's radio have enough Program mixes to eliminate most if not all interaction. Believe it or not but my Venture with JR531s flew just as good as it did with Futaba 9252 digis with no visible or apparent interaction in flight.

As good as the Falcon flies I can just imagine how the Raven would fare. I just didn't like the servo arrangement. Kind of a lame reason but it left me a little unenthused.

It sure does seem a bit cheesy to me too.

Anyone fly one that can comment on strength and durability?

Strength and durability of Raven 50...

It's a pretty solid heli, I must say. The only part I've had a real problem with, durability wise, was the stock boom supports can shear at the flattened part where it connects to the frame in a hard landing. I've been practicing a maneuver that some people might call an autorotation, and needless to say my landings aren't the softest, and I managed to break a boom support on one of my better ones:P. Replaced with carbon supports with machined ends and now no problems. My first crash I balled it up to the tune of $250, broke the tail boom in two places, but the torque tube survived unscathed.

It also flys very smoothly and can be set up to have a lot of cyclic speed. It will fly a whole lot better than I can fly it.

$250????????????????

What the heck did you do to come up to $250????

Please tell us. Does that include blades and all?

I balled her up pretty good...

The crash was a straight-up dumb thumbs maneuver, but I do blame some of it on the slow roll rate of the beginner setup. Basically, I got nose-in in FF at low altitude in a left hand banked turn, and zigged when I should have zagged (left aileron instead of right to level it off). I immeadiately realized what I had done and fed in full right aileron, but it was too late. She went in nose down and on her left side pretty hard, which broke off the throttle pushrod. This caused the throttle to go to about 3/4 and the heli beat itself to death. The thing that added a bunch to the bill was that the boom supports ended up getting caught up in what was left of the blades and wrapped around the rotorhead, which busted up the head, washout and seesaw pretty good. And the $250 includes replacement Aerotech woodies, not the stock Hurricanes.

A short list of damage:

Blades, tail boom, boom supports, fin set, tail rotor hub, tail gears, both lower frames, landing gear struts, pushrod and ball link set, upper mainshaft bearing, main gear, clutch and liner, main shaft, flybar, spindle, washout assembly, seesaw assembly, flybar control arms, blade grips, gearset for Futaba 9252 servo.

It was pretty bad, but imagine what it would have cost to replace the above on a Fury or Vigor?

Ouch! Did you get 'er all back together? I know just what it looked like. I did something similar to my Raptor a few weeks ago. Wasn't worth putting back together. I'll be spending my money on a new Falcon. Good luck! Dave

Some tips......

Here are some tips that could save you and others some money in the event of the unlikely:

1) Throttle return spring. I HIGHLY advise the use of one. Just get a cheapie little spring from the auto parts or hardware store and attach it from the throttle arm to the frame. Use enough tension to close the throttle with the link popped off the servo horn. That is all you need.

2) CF boom supports. Alot of people don't see the hoopla around these CF upgrades. Many are eye candy but a CF boom support WILL NOT bend and certainly not wrap itself around the head like bailing wire. Boom supports always seem to end up there if you get a chicken dance. Another good reason to do the throttle return spring. Also, they tend keep the boom fairly well intact protecting the CF torque tube.

3) Tail blades fairly loose in grips. If you run the tail blades tight and brush the ground you more than likely get to replace the tail gears or main gear. Run them a tad loose.

4) Main blades faifly tight in grips. Keep your main blades tight in the grips. This improves the likely hood that they will not fold out on auto and strike the boom. I keep mine tight enough that it takes just a smidgeon of effort to get them to fold back for storage.

5) Properly working clunk lines. For the inverted stuff you HAVE to have a properly working clunk line. One that does not rest on the wall of the tank restricting fuel flow. Conversely, make sure that it is not to short and fails to reach the tank bottom either upright or inverted. Another area to watch for is using to heavy of a clunk. The fuel line in these kits is usually very thin walled and flexible make sure that you cannot shake the tank and get the assembled fuel line to fold over in the tank. This almost always pinches the line closed causing the pilot to practice inverted autos with a touchdown on the headbutton!

Just some ideas that I have tried to implement in my building and setup. I hope they are useful. I am no means an GURU but if I can save somebody $20 bucks with this post then it was worth the effort.

Driftrider,
Man, that is the kinda crash that sends most people out of the hobby. When the cost or repairs exceeds 50% of the kit value you really have to pucker up! That is one reason most of these "low end" helis seem to become replacement cost items. Hang in there dude!!

Took me a month to fix her...

...but she's flying better than ever. Just had a recent very minor crash (botched auto/tipover) that only damaged the main blades and put a ssmall dent in the boom. The head speed was so low that only the covering was split off the tips of the blades. Crashes suck, but I'm not going to quit because I know that even the greatest pilots ball one up every now and then.

throttle return spring

Hey Lift,

could you post a pic or send me one of your throttle spring setup. I'd like to eyeball that one. Also have you experienced any glitches with this setup?

Thanks,

Lift.....Payton.....

......I've got to hand it to you dude!!!! That spring idea is GREAT!! Did you come up with that all on your own????

IF you did, MY HATS OFF TO YOU....IF you didn't, well that's OK, thanks for posting it. I'm going get one of those today.

Nope not me

Not on helis. I think someone beat me to it. But, I did it on 1/8 scale buggies for years.

One of those goes WOT(wide-open-throttle) at 60 mph and things get messy quick too.

Throttle return spring.

RCPylon,
Hey unfortunately I don't have pic of it. I have been trying to borrow Dad's digi cam since last weekend to get some shots of my setup on this Falcon.

RF noise. Just to be safe I used a insulated wire through the frame making a loop then attached a spring to it. You don't have to worry about it with a platic framed heli but the Falcon SE has metal lower frames.
