The RCFW Hellcat Group Build
 
4 Attachment(s)
The time has come to launch an "official" group build thread for the R/C FrameWorks Grumman F6F-5 Hellcat. For those who have been following the "Guaging Interest" thread you already know what this is all about. For everyone else I will give a brief history of the project to get you up to speed.

R/C FrameWorks is what I call my little side business of designing and producing accessories for the scale builder. ( All three of them left out there! ) :D The Hellcat is my introductory plan / short kit offering and in an attempt to entice a few more builders out into the open I have decided to try a group build and taylor it somewhat to the "newbie" warbird builders. If you are at all interested in the idea of building a Hellcat and doing it with a few other like minded modelers then please visit the web site at the link below. There you will find all the information on the Hellcat itself, how it came to be, what kinds of things will be covered in the group build, and how you can get involved.

www.hellcat.cwvmodels.com

Here are the specs on the airplane:

Scale: 1/8 (1.5" = 1')
Span: 64.25 inches
Area: 652 square inches
Weight: 9 - 11 lbs.
Wing Loading: ~32-39 ounces/sq. ft.
Volumetric Wing Loading: 21-25 pounds/cu. ft.
Power: .61-.91 two stroke/.91-1.20 four stroke (or electric equivalent)

As of right now the RCFW prototype has flown half a dozen times and has exceeded all expectations. All test flights were done prior to detailing and painting (My Momma didn't raise no dummy) and the airframe is currently stripped down so that the finishing process can proceed. My intentions are to do the finish work on the prototype as well as to continue to develop the construction gallery on the web site while the group gets started on the airframe. By the time the group gets to the point of finish work the prototype should be done and the web site complete. That's the plan anyway! If you have any questions or input please feel free to post them here. And if you would like to review the "Guaging Interest" thread mentioned above it can be found here:

http://www.rcuniverse.com/forum/m_8962908/tm.htm

I will probably wait a couple of weeks to let everyone who is interested get their orders in and processed before starting the actual build. If you are interested and want to get started with the group please get you orders in ASAP so I can get the kits produced and shipped. Of course, kits will be available and you can join the build at any time in the future if you don't mind playing a little "catch up". ;)

I would be remiss if I failed to thank a couple of retailers who have agreed to sponsor the build with discounted merchandise.

Ray and Robin's Hobby Center in Falmouth, Maine
&
Pete's Pilots

More information on the sponsors and links to their web sites are available on the Hellcat site.

Well, there you have it. I am very much looking forward to building with whomever decides to jump on board. Thanks for your interest!

Regards,
Chad Veich

Hi All
I have to let every one know what a cool plane this is. I flew Chad's Prototype and I found it to be one of the nicest flying warbrids. It flies like it is on rails and will do anything you ask of it with in reason for a warbird. (NO 3D!) I recently got my kit. Great design, Nice scale lines and everthing tabs together. I am not a super accomplished builder, though I started on the center section of the wings and this kit will make you look good. In less than an afternoon I had it framed and sheeted. I will start posting pics soon hope everyone enjoys theirs as much as I am.
Thanks
Tighe O'Meara

Thanks James for your order and thanks Tighe for the endorsement.

By the way, Tighe already has his kit because he is the guy doing the laser cutting! ;)

For anyone interested in having a look I put up the construction gallery for the vertical fin today. Please let me know if you find any links that are not working or anything that looks strange. I've viewed the site with Explorer and Firefox and all seems well but you never know.

Barcandson,

Did you receive the order information? Just want to be sure nobody was missed.





Not much to report as far as progress on the finish of my prototype. Most of the last couple of weeks has been spent getting everything in place to produce kits. I have made a bit of progress to include getting the landing gear shortened, cleaned up, and repainted. I've also added the aerial masts, the waste gate in the belly, and am working on getting the drop tank installed. We had a scale fly-in here in town this weekend so I "polished" it up a bit and took it out for display as can be seen below. No sales but lots of good comments. For anyone who was at the fly-in yesterday and could not find me, I apologize. My plans were foiled and I did not get out until today. Onward and upward!

PS - This is the waste gate in the belly pan. These parts are vacuum formed and will be part of the optional exhaust outlets package. Sorry for the fuzzy pic!

RE: The RCFW Hellcat Group Build
 
Just FYI, I have added a reference page to the web site as well as started a "tips & tricks" page. Both can be found in the construction gallery. The reference page contains links to several nice on-line Hellcat pictorial sites and also offers up some Hellcat books that you might consider for your library. I will continue to add to the tips & tricks page as the build progresses and we reach those stages where I think I have some info that may be of some use. If there is anything in particular anyone would like to see covered please let me know. Thanks guys!

Chad,

I don't know anything about the Hellcat. Does it have flaps on the full scale? Just curious.

Barry
www.canopyrailsforwarbirds.com will give 10% off the cost of my rails if purchaced for this build. I take it that it had a sliding canopy.

Chad Veich 10-26-2009 08:21 PM

RE: The RCFW Hellcat Group Build
 
Barry,

Thanks for the offer of discounted canopy rails. I'm not putting a sliding canopy on my prototype but some of the other guys may take you up on the deal. The full size does indeed have flaps but I did not want the weight or complexity on this rather small sport-scale airplane. They could certainly be added if someone were so inclined but they are not necessary as long as the weight is kept in check. I will simulate the flaps on my airplane when I do the detail work.



Gianluca,

Thanks for the kind words, much appreciated.

Thanks for the feed back Chad! Nice looking sport plane. Although I think it looks like it could be detailed and be a masterpiece.

RE: The RCFW Hellcat Group Build
 
hi all
I have completed the center section and the left wing panel. I have add rockets to my plane so there will probably be an add on kit for these. i also installed nav lights. I found LEDS at radio shack in a variety pack, they are already the proper color and just about the scale size (3mm) in the wing tip. the package also comes with 5mm lights which are great for lighting instrument panels and the nav lights on the spine of the aircraft. I will be adding pictures next weekend of the winfg panels and the rockets.

my next decision is on the flaps
do I go scale? - would have been easier from the begininning

non scale?

skip it ?

Truth is the plane files and lands fine without them - would just be a nice scale feature

RE: The RCFW Hellcat Group Build
 
Question. Any larger planes on the horizon?

I like the concept and it sounds like fun with the added comradeship, but I would say, many of us builders have moved into the larger war bird scales, 1/6 and 1/5 etc.

I have a Jemco P-47 (1/8th scale) that still sits unfinished after about 16 years. Just lost interest in the smaller nitro size and haven't gotten back on it yet.

These larger scales can easily be detailed to the max and still not be too crazy in wing loading. With advancement of very reasonably priced and reliable gas engines, these scales have never been so easy and fordable to power.

Perhaps a 1/6 scale Corsair or even a larger version of your Hellcat? I like the 1/6 size as they are still large enough for the smaller gas engines available now, parts are larger and easier to detail IMO, and fairly inexpensive 12" full body pilot figures are easy to find for them.

Anyway, this will be a fun process to watch. Wish you all a good time.

The 1/6 Corsair is already under way, although stalled for the moment while some other things get finished up. Please note that this started out as an enlargement of the Royal plan but has evolved into a totally new design.

http://www.rcuniverse.com/forum/m_7335038/tm.htm

A larger version of the Hellcat is a very distinct possibility. However I probably will only go up to 1/7 scale which would be about 74 inches span. Any bigger than that you already have the Jerry Bates, Nick Ziroli, Don Smith, Don Lien, Iron Bay, and probably some others I'm forgetting. Other warbirds are being considered in the 80-85 inch range however, including a Yak-11 (see link) which is being prototyped as we speak as well as some others.

just to ad my two cents

there are a number of .60 -1.20 size gas engines available on the market now at extremely resonable prices

not only are they more afordable to opperate they can swing bigger scale props

this 17cc has got great reviews with comprobale weight

This all sounds good. Good point on the choices in 1/6. Maybe 1/5 then.:D I'm building a 1/5 scale Meister now. Maybe a 1/5 scale P-40 or British Hurricane then. Lots of Spits out there to.

I don't know anything about it, but the RCG 26cc gasser might work too. Apparently the listed weight is wrong as the first of the reviews says the total weight of the engine, exhaust, ignition and hardware is 1297g.

On a 64" war bird??????????????

Tko310 11-02-2009 12:56 AM

RE: The RCFW Hellcat Group Build
 
I know the RCS SV 17 cc is 33 oz without ignition and battery i believe the total package depending on battery choice is approx. 41 oz

the proto type flew with a OS 61fx, plus 7-8 oz of nose weight.

acording to tower the OS 61 weights 23.6 oz with muffler

RCGF or aerovate makes a 15cc also this might also be a good choice though i have not looked into it yet

Tko310 11-02-2009 01:03 AM

RE: The RCFW Hellcat Group Build
 
i agree he 26cc might be a bit much

could be entertaining though

Tko310 11-02-2009 01:07 AM

RE: The RCFW Hellcat Group Build
 
the 17cc is approx a 1.10ci engine totaly in the realm for this model

i have seen a lot smaller with a lot bigger engines racing


the power in these gasers would allow scale size props in addition to alot less mess

I had a Gee Bee R2 a few years back. Flying was OK including the take off. Landing was a different story. Planes that are all engine are not fun to bring home. A detailed war bird with hours and hours of work in it would not be my first choice to experiment with in this way. But to each his own, as they say.

Yes, a 26cc on a 64" plane wouldn't be for a beginner pilot or anything. For the right pilot, the RCG 26 sure is a cheap way to turn a 19 or 20" prop, though.

DaddySam 11-02-2009 09:57 AM

RE: The RCFW Hellcat Group Build
 
I had a RCGF 26cc on a 10.5 lb Edge and it was anemic. It would fall out of a loop if you weren't careful, and the best prop for it was a 17-8 if I recall correctly. I'm currently running a DLE 30 and it is night and day - almost crazy fast power. I see the 17cc has something like a 38 oz wt, which seems pretty heavy. Depends on how much nose weight would be needed. I'm not sure now big a scale prop would be (I like them too) but the 17cc was spinning something in the area of a 14x7? Not sure if that's scale or not.

RE: The RCFW Hellcat Group Build
 
The scale prop is ~19.5 inches in diameter and I don't think there is anything you're going to stick up there that will turn that large of a three blader except MAYBE an electric power system! I'm looking at the possibility of either electric or the RCS 17cc gasser for my next Hellcat. Whatever you decide on if there is a chance of your Hellcat ending up much heavier than 10 pounds I would definitely suggest you look into the Sierra retracts and stay away from the Robart units, especially if you fly off of grass or dirt.

One of my local flying buddies is going to build a Hellcat for warbird racing and will be putting a YS 1.40 up front. To that end I have re-designed the wing slightly to take a 1/4" plywood dihedral brace so the extra weight and power of some of the engines being considered here should not be a concern.

One engine would be the RCV 120 4-stroke. It is geared, compact, and very powerful. I had a 20 X 12 2 blade on my Gee Bee R2 with that engine. It was amazing. It is perfect for war birds because it swings large props at less RPMs. Fits very nice in a 75" Mustang as well.

Not onlydidhe buy me dinner and a big slice of pumpkin pie, butChad even let me tire-kick his Hellcat prototype!

OK, I was wearing flip-flops so I could not do much damage, buty'all can best believe thatthis is oneVERYcool airplane! http://www.rcscalebuilder.com/forum/...s/smiley32.gif</p>

After a while the paparazzi urge came over me, and so now just<font color="#810081">click here to check out the slide show!</font></p>

p.s. MAXIMIZE the slide show page for best viewing; you can also pause any image, tinker with the slide show settings, and/or click back to view the photos as I postedthem onYahoo's photo site, Flickr.com.

This is my center section. Chad's design makes this a snap to put together. The shear web is 1/8 ply that is notched for all the formers. Once everything is tabbed together the shear web is capped with stringers top and bottom. The retract rails are also incoporated into the main spar in addition to the a short brace interlocking with the ribs. This makes life really easy. All said and done i had my center section framed up and sheeted in about 3.5 hours.

Chad will be posting detailed pics on the hellcat web page i am just providing feed back and my progress

The next step was to build the outer wing panels. I started with the right panel first. as you can see from the picture I wanted to add rockets to my plane. So after the basic frame up of the the wing and the top skin attached I designed my hard points, pylons and rockets. I felt it was better to do this before proceeding with the rest of the wing because installing hard points after the sheeting goes on would be much more difficult.

this image is the completed right wing panel

I will go into further detail in the next posts
