"Century" 90 Scale Bell 222

Lamar Cooley

Senior Heliman

Houma,La.,U.S.A.

I've been contemplating a scale heli build for some time now. After monitoring "Runryder" and "Helifreak" "Scale Fuselage" forum's for awhile and seeing all the great builds,tips and how-to's shared and passed along. I'M IN .
For my "First scale heli build", I've chosen the "Bell 222". I've been a scale warbird,aerobat and sailplane nut for 40 years so this will be a new adventure for me. Any "build", especially a scale one is always: FUN,EDUCATIONAL,GRATIFYING AND SATISFYING. I'll try my best to share my experiance with you all. I'll be asking for help. Which I've already done. As well as passing along my progress,
problems,solutions, observations and evaluations. I'll also have photos of the build in gallery. Soooooo here we go.
I chose the painted, 90 size version, because I already have mechanics to drop in and "Century-Funkey" has done an outstanding "finish paint" job on this line of heli's. I'll be utilizing "Raptor 90" mechanics, "which should" be a "drop in" for this project.
The heli arrived in a rather large "shipping" box: 59"lx21"wx11"h.
Good thing, because it did have some "battle scars". Opening the "original" box to inspect for damages, I found everything was well packaged:fiberglass parts wraped in paper and foam,all other parts in plastic bags. No damages...Oh Boy.
I found beautifully painted fuselage,top hatch,horizontal and vertical fins,"instruction-build" manual,long plastic tube with linkages. The windows,wood parts,foam piece and screws were packaged in plastic bags. Next step; Reviewing the instructions (8 pages).
The manual has 3 assembly-construction "stages".
1.) General Installation.- pages 1 and 2
2.) Installation of Retractable landing Gear("Century brand"page 3
"Note": Page 4 - Mesh Template
3.)Installation of "your choice" Mechanism.-(page 5. for "Century Predator".) (page 6. for "Hirobo Freya" (page 7. for "Thunder Tiger Raptor"
"Note": Page 8. (not numbered) "Optional"-Retractable landing gear: "Century part numbers".
Other interesting observations: The following steps of assembly have already been professionally completed: 1.Wire mesh for ventilation ports in fuselage and top hatch(templates included in instructions).
2. Top hatch aluminum "alignment" pins and plastic mounting brackets.-3.Fuselage plastic mounting bracket "retainer" plates mounted with screws painted over.-4.Fuselage plywood "alignment pin retainer plates"-5.)Exhaust pipe-tubes.-10.Fuselage and hatch "light lens covers".-11.Tail "hatch" to boom, plywood "mounting plates".-
13.) Vertical tail fin "light lens cover" and wire.
O.K. This completes "PHASE ONE". I'll be back later with "News ,Views and Notes" as the build progress's. Man....this is FUUUUN.
YOURS....."In the brotherhood"

Installing Mechanics

Installing the mechanics begins with a trial fit of the Raptor 90 mechanics. It is necessary to remove the header tank, it will not be used. I also removed the "rubber band" servo tray tabs(2). The "Mavrikk" muffler required removing some material from the already installed rear fuselage former. As well as shaving down the bottom top edge of the former to allow for tank clearance and allowing the mechanics to slide back far enough to center the main shaft into the top hatch rotor head hole. Careful fitting and measurements reveals a little work to be done in order to use the included plywood rear mount base plate. The raptor tank has a nipple on the bottom which extends below the frame base which does not allow the frame to sit flat. To get around this I will use a carbon fiber base plate and four small washers under the frame holes. The mechanics still "rock" left to right but not as bad now
The instructions call for a 76.5mm wide x 212mm long bolt pattern(center of hole to center of hole). I found my mechanics would require a 77mm wide pattern but the 212mm length was right on.
NOTE: The provided "Raptor base plate" had it's holes predrilled at 77mm from inside edge to inside edge. ( I will not use them )
This 77mm width was varified because I will be using a carbon fiber base plate. The carbon fiber base plate made laying out the pattern on the bottom of the heli an easy chore. But before I committed to the bolt pattern. I found it necessary to do some fine tuning to the plywood base plate. The "rounded" bottom back and sides required some extra beveling and a shallow grove to the bottom center in order to move the base plate back far enough for a good flat fit. This then changed the line up of the base plate holes to the heli. No problem. Once I was satisfied with the base plate fit. It was centered up left to right and epoxied in. At this point the existing holes in the base plate were filled with epoxy. (They would not be used) Next I Carefully measured and layed out the bolt pattern on the bottom of heli.
TIP: I used a black "Top Flight" panel line pin for my markings. Highly visible and removable with alcohol. The important part here was making sure the rear base line,front to back, was correct. I used the 29mm measurement as instructed in the manual. Once satisfied with this measurement I then established the center line, found the center line of the carbon fiber base plate and used the base plate to determine the location of the four mounting holes. Holding up the fuselage to the light. I could see the center line and base line so I could locate and mark them on the inside bottom for the fuselage. I then centered the base plate on the center line and centered the rear mount holes on the base line. I taped the carbon base plate to the inside bottom. Installed and centered up the mechanics to the base plate,installed the top hatch and varified the center of the main shaft. Looking good at this point. Removed the mechanics and used the base plate to mark the four mounting holes on the inside.
So, decision time. I decided to go with the mounting hole location determined by the base plate rather than the pattern layed out on the bottom. This pattern would keep the main shaft centered to the top hatch rotor hole. O.K. drilled the holes and to my amazement the holes lined up perfectly with the bottom outside pattern holes.
Next will come mounting the mechanics, installing side frame mounts and installing the boom to make the tail pod cutout for the tail rotor case.
Note: As seen in the photo of the base plate; the "rear holes" will be used, the "front outside" holes are filled with epoxy.

Build Photos

Hello GrantL,
I have the first photos of the build in my gallery now. Sorry for the delay. You'll also find a photo of the "Eurokit" gear's. Thanks again for the lead. I'll have some more soon. I've installed the mechanics side frame mounts and horizontal fins. I'm working on the tail pod now. I'm also sizeing up the landing gear install and investigating landing light control options.
Regards

Tail Pod and Fins

Today I got around to cutting out the tail pod (tail hatch) for the tail rotor case. The "cut out" drawing and measurements in the manual are for the standard TT tail case. I'm using an "Elevated" aluminum tail case, so some custom fitting and cutting were in order. There were 3 plywood "pod (tail hatch) mounting plates", one on top center and two on the bottom (opposed), already installed in the tail boom. The manual indicates self installation of these plates with two on top and one on the bottom. "Oh well". The cut out eliminated one of the two bottom plates so I had to relocate and installed another one. Leaving them as one on top and two on the bottom.
Note: "Century" provided 6 pre-painted mounting screws for the pod (tail hatch): two top (blue)and 4 bottom (black).
Of note: I found it necessary to remove the baked on enamel paint from the threads of these screws
I also installed the horizontal fins. It took a little time and tweaking with a jewelers file to get the fit just right for my taste. Still not satisfied with the fit, a small fine fillet of black silicone sealant made the top and bottom joints invisable. Tomorrow I'll tackle the frame to fuselage mounts.

Nose gear door and steering

Gentlemen,
A couple of questions.
1.) Is the Bell 222 nose gear "Steerable" ?
2.) In observing Mr.GrantL's "Bell 222 landing gear build". I see a third gear door affixed to the nose landing gear leg. Is this door utilized on the real thing.
My searches haven't turned up anything on either of the two above.
Thanks in advance for any and all help.
Regards

to answer the first question: yes the nose gear is steerable.
the second question: The main doors open, the gear drops down, then the main doors close back up. The small door affixed to the main nose gear remains open until the gear is retracted in the upright position. Hope that helps. Check copterdoctor's gallery for some detailed pics on his bell 222/airwolf retracts. At the bottom of his page there is a video as well.

Lamar,

If you go to this site:

http://www.airliners.net

Do a search for Bell 222 and you'll get lots of ideas and no two are the same..

Gear doors

Hello Mr.Grant,
Thanks for the lead. I've been aware of this site for some time. It has been one of my main resources for scale thingy's on planes and heli's. In particular "cockpits". Of note, all my findings to date have not shown a nose gear "third door" in the configuration you utilized in your "retract build". All I've found indicate the
"leg door" seems to fold back and lay almost flat to the fuselage without the "small bent tube from leg to door"
Nevertheless I do intend to include a third door in my retract build. More than likely I'll do the same thing you did to solve the problem. As an aside, I have to get around the "Raptor" fuel tank so I'm planning to construct a "double bell crank" placed behind the tank in order to "connect" the two main gear. I've also made some other modifications to accommodate my particular install. But still utilizing your basic principle of "one servo to activate all 3 legs" On the other side of the coin. I'm still pondering a way to get steering for the nose gear. Any ideas ?
Thank you and all for the interest and guidance.
Regards

Hi Lamar,,

First.. Just Grant will do.. no Mr..

The design for the "One" servo gear retract belongs to the "CopterDoctor" here on RR... You might want to ask him what he thinks.. He's done quite a number of these mods... With regard to the steerable nose gear... I personally wouldn't go that far on getting it scale looking.. I'm pretty anal about this stuff and think you may be going a bit deep.. If you fly off grass, you won't see the results of your labor... Just my 2 cents, and I'd probably get change as well..

Hey Lamar, i agree with Grant on the steerable nose gear. it isnt worth the hassle of making it steerable. first, you have to come up with a way to make it go back to center when you pick it up off the ground, you dont want to retract it if it isnt centered and second, steering with a pivoting nose or even a tail wheel isnt as easy as it looks, believe me, i have a blackhawk, a seaking and an apache and it takes practice making it look good especially on concrete. lastly, you can still steer it left and right even though it doesnt pivot. to taxi, you gotta have it light enough on the gear to roll and this makes steering easier as i have found with the airwolfs and 222's i have built.

Gear build

Hey Grant,
Thanks for the reply. My hats off to "CopterDoctor" and also
"dcavy".(Guy's) I appreciate the words of wisdom concerning steerable nose gear and grass fields. Sorry...no refund. I think you will agree that it's sometimes not "should I do it" but "CAN I?" do it.
As, bi-enlarge, its how we derive, our "scale" building pleasure. Seldom seen or noted by others but appreciated by those who know what it took and takes to accomplish such trivial things. At this time the jury is still out deciding if my brain and intestinal fortitude are up to the challenge.

Bell 222 60-90 build

Some of the latest photos of the "gear build" for this project.
When I'm satisfied with the "completed" components install. I'm planning to do some fiber glassing of most if not all the wood work for strength and fuel proofing.Regards
