Century Bell 47 scale build

OUCH!

Donnie D

Started "dry fitting" my electronics and fabricating battery and motor mounts today. Pics later.

You are smokin' right along. How about a picture of the finished color scheme, if you have one?

Hi Chief,
How you doin partner. Hope you can make it to Fatdaddy's funfly next year. I'm gonna try to. It'll be good to see you again.

I'm gonna keep the yellow canopy and tail truss. The mechanics will be dry brushed a silver grey sort of color. It looks like aged metal that way. I've done a little area on the tail mechanics as a test, and it looks pretty good. I haven't done any decal work yet, but probably will do some this week or next. I've done just a little "dirtying up" work, but not much. (Hydraulic fluid splatters on the fuel tank area). I'm not gonna do any scale work to the cockpit at all until I get it flying. I want to keep the mechanics as stock as possable until then. The cockpit scale work requires a lot of changes to the servos and the electronics and I want to make sure I can get her in the air first, know what I mean. Fatdaddy is helping me with the motor conversion part, thank the Lord.

I've almost got all of the electronics mounted (hate all those wires, they're a pain in the butt) and I'll be posting some pics later this week.

OH, by the way, like I said, I'm gettin ready to start making up some decals. I have the decal paper. Do you think the decal stuff you use to make the decals edges blend in is necessary? I didn't buy that stuff, but I can get it if you think it is worth it.

Hey Donnie, After you print your decals there are two things you have to do. The first is to "fix" or waterproof them by spraying them with a fixative. The second thing is to make them lay flat and conform to the shape of the object you are applying them to. That is done with a decal solvent. You also want to apply the decals over a gloss surface, either clean plastic or gloss paint.
Making the edge "disappear" by applying one or more coats of clear is another step. That step is optional, but you may want to consider it because it will protect everything, weathering, oil streaks, rust, etc. Also it is common practice to dull down the finish on models to a matt or semi-gloss finish to make them look more realistic.
I would recommend that you put a couple of junk decals on the sheet to practice with. These print yourself decals are a little different than what you may have used in the past. They have to be slid off the paper without letting them curl under, it's almost impossible to straighten out if it does.
It may sound complicated, but once you start doing it every thing will fall into place.
PM me for my phone number if you have any questions or just want to talk.

I just finished printing my first sheet about an hour ago, and I'm letting the clear spray protectant dry awhile. I did print a few extras to practice with. I'm gonna go try one in a few minutes. I'll let you know how it works.

Hey Chief,

Those decals work great. I'm printing out some others that I'm gonna apply tomorrow. Thanks for telling me about em at the funfly. Pics later this week.

Hey D it's me Skyhunter..... So this the Bell 47 huh!.....

Here is what i build M.A.S.H Bell 47

Hey Skyhunter. Welcome aboard. You are gonna like this forum. There are a lot of great folks here. We try to look out for each other and help each other out. Some have a good bit of experience, some are complete noob's, most are like me, kind of in the middle.

Hey, where in the heck did you hide that battery? You would think a bqtt like that would be the size of a brick.

Donnie D

Hey Donnie D, Thanks you....

If you see the Video you can see the battery 0:09 It’s the two long black things lying on the stretcher on the side of the heli then I box them up with the confin box when done.

Well we are all at same level then i still have alot to learn D.

Thanks.

Don't we all. So you are using two batt in series. That's what I'm gonna use. I'm not doing the Mash version, but my batts will still be mounted on the skids, but in close to the frame, and I'm gonna disguise them as auxillary fuel tanks. I think that will go over well. I have my electronics all mounted, my ESC programmed and the Bell 47 is programmed into my DX6i. I'm just waiting for one extention wire for my gyro signal lead to arrive from Heli Direct and I can finish my wire routing, plug everything into the receiver and bind the rec to the transmitter. Then I can start setting up my cyclic. I don't need the motor installed for that stuff. I'm trying to get as much done as I can until I can get the motor and clutch installed. I'm gettin there.

I'll post more pics in a couple of days.

Hi Donnie D, Here is your request!

Oh yeah, I sure love scale helis.

I know you know this, but I don't think I've mentioned this in this thread yet, but the Bell 47 uses a 90 degree swash and mechanical CCPM.

Donnie D

Sorry

HUH?

Donnie D

Sorry I was on my phone when I reply.... i ment to hit cancel insted of send.

Skyhunterhobby,

Just out of curiosity, did you scale out the cocpit on your Bell 47? I plan to do mine, but since it requires a fair amount of modification, I'm gonna leave it stock until I get her flying.

Donnie D

Matthew 22 : 35-40

Hi Donnie, No i dint not scale out the cocpit no time :) but if your putting a pilot you will need a 10" pilot guy.

Good site to look to copy Bell47 Cockpit and any other detail.

Just finished binding my DX6i to the reciever. Everything seems to work, all 4 servos move. Kind of wierd to see just one servo move when you give collective or cyclic input. Kind of neat to be doing a mechanical CCPM heli though. It's a learning experience.

Anyway, next step is to make my servo horns and get them set to 90 degrees and hook up the rest of the links and start setting everything up. Gettin close and I'm really lookin forward to seeing this thing fly. Nervous as all get out too.

More pics this week.

Thanks for lookin,

Later

John 11 : 25-26

OK, this morning I got all my servos to 90 degrees, made up and mounted the servo horns, attached the linkages from the horns to the bellcranks, set the endpoints on the Aile and Elev servos and tested the travel on everything. Everything seem to work great. I was worried because I had never even heard of mechanical CCPM before this, but everything in the swash movement is very smooth and the swash stays level from bottom to top. If it flys as well as it looks, I'll be a happy dude.

Next is making up the main blades, getting my motor mounted, (gotta figure that out, but I've got a couple of ideas), and setting it all up. Maybe it won't be much longer.

Gonna try to take some pics later today.

Thanks for looking,

Donnie D

Hi Donnie, I just send you PM see if that help.

Got a LOT of scale detail work and paint work to do. The little wooden boxes just behind the cockpit are dummy batterys. That's where I'm gonna mount them and disguise them as auxilliary fuel tanks. Next is main blades and motor mounting. Boy, I'm gettin kinda nervous...and excited.

Thanks for lookin

DonnieD, Lookin Good Bro. Dont be nervous man this thing is going to blow your mind when you put it into the first hover,
this size heli is stable as can be. You'll see what I mean.


sdjb

Donnie D, it's getting there man!... keep it up.

Hey Donnie. The decals look really GREAT. On your battery box covers, one could be an equipment storage box type of thing. Again GREAT JOB!

Thanks guys, I hope I'll have it in the air before too long.
