Default 1/6 Scale Hellcat

Truth be known the last thing I need right now is another project. However, after some prodding from various sources, I've decided to forge ahead with a 1/6 scale enlargement of my smaller Hellcat design. Because of my heavy schedule I have enlisted the help of my brother to get this thing built and between the two of us we should be able to get it done although, for certain, it won't be fast. Hopefully it will be steady though! For the most part the design is a direct enlargement of my 1/8 scale airplane but with a few changes to, hopefully, bring it up to a contest level effort so we can fly it in team scale competition. Anticipated changes include scale hinging on all the flight controls, scale slotted flaps, a power operated sliding canopy, full cockpit, and a few other minor nips and tucks for the sake of scale fidelity. As usual I hope to make the plans, laser cut parts, and accessories available once a prototype has flown successfully. Here are the specs:

Scale - 1/6
Span - 86 inches
Area - approximately 1350 sq/in
Weight - shooting for 25 lbs but 30-32 is within reason
Retracts - Sierra Giant mains and Robart tail wheel
Power - we will be using a G62 in the prototype
Construction - traditional built up with a glass cowl, belly pan, and a few other parts (We plan to build a second fuse to be used as a plug for a potential glass fuselage option)

Here is a comparison of the relative sizes of the 1/8 and 1/6 scale airplanes. The bigger bird has substantially more volume, not to mention wing area. Based on how well the smaller one flys we are VERY excited by the potential of the bigger one. If we can come in anywhere near 25 pounds it should be a big trainer.

As is the standard practice construction began with the tail surfaces. The vertical fin is actually much further along than shown but I have not snapped any pics of the progress. Much to my brother's chagrin I have decided not to use the horizontal seen here and am currently re-designing it. For reasons I cannot explain I used a much thinner than scale section on the 1/8 scale model and did not catch the error until just a couple of days ago. Since we are attempting to make a contest quality airplane here the decision was made to start over and do it right.

Most of the parts have been cut for the fuselage and the firewall/fuel tank/wing saddle box which forms the heart of the beast has been primarily assembled. Here it is shown with a few formers and stringers set in place for a quick look. We hope to get the jig fixtures in place and start gluing this weekend.

I have the Hangar 9 Hellcat .60 ARF.
It's a nice plane, I'd like to get a larger one, someday.
I look forward to following your build, especially the detailing you are planning. I always learn a lot from these types of build logs.
Thanks for sharing.

This would be a nice companion for my Corsair. Subscribed! I hope you are taking pictures as you progress.

Chad, your my hero. Looking forward to this build. Shows just how large this baby is. At 1/6 scale it is the same size as most 1/5 scale warbirds.

Thanks for checking in AB Bob and welcome aboard. I will do my best to keep your attention!

Not to worry FlyerInOKC, there will be lots and lots of pictures to share. I too have a 1/6 scale Corsair in the works that I hope will one day share hangar space with the Hellcat.

Thanks Ram-bro and you are certainly correct about the size of the Hellcat. While the P-47 is considered the largest single engine WW2 fighter that title must be based on weight as the wing span of the Hellcat is larger. In terms of volume the Hellcat would certainly win over the Jug. At 1/6 scale the span of the Hellcat is just under 86 inches compared to 81.5 inches for all versions of the P-47 save the N model. Even the extended wing of the P-47N is a bit smaller than the Hellcat's span at just a fraction over 85 inches in 1/6 scale.

As noted in my original post the model will be designed around the Sierra Giant main gear as seen below. I've yet to have a set of Sierra gear that were not top of the line and I expect these will be no exception. They will get a bit of scale "eye candy" added to bring them up to competition standard.



The airplane will ride on a set of 5 1/2 inch scale wheels from DaVinci Machining. These things are cool!



The tail gear will be a large Robart unit and with just a bit of dressing up will do a commendable job of simulating the full size.



And here is a look at the "quick and dirty" set of fuselage and tail group drawings being used to construct the prototype. The finished plans will be substantially nicer to look at!



Hopefully the weekend will see some progress and I will have more to share in the week to follow. Thanks again guys!

Truth be known I've built 2 Hellcats, one scratch build, and haven't flown either yet. [] More embarrassingly, I've only flown a foamie version.
Great project though Chad, and a favorite. They certainly do have a thick tail section also. One of those things where there's no escaping a bit of tail weight, to do it right. Do you have a supplier for the cowl, or will it be a hand made glass mold?

Hello Bill,

Thanks for checking in and nice little Hellcat you've got there. Is that a Guillows? Regarding the cowl and other items to be offered in fiberglass I will make the plugs and then have a third party do the actual molding of the parts.

Thanks, it's a 125% Guillows scratch build of around 40".
I figured there may be cowls available at your scale, but there's nothing like making the part exactly the way you want it, by making your own plug.

Default RE: 1/6 Scale Hellcat

We got some time in the shop today and a fuse is starting to take shape. Had to stick the tail feathers in place for a look. The horizontal you see here will not be used as I discovered that the airfoil is much thinner than scale. Not sure how I overlooked it when designing the smaller Hellcat. It's not all that noticeable on the 1/8 scale model but in the larger scale it becomes more apparent and, since we may compete with this model, the decision was made to start over and do it right. A new horizontal is being designed as we speak. Next step in the fuselage construction will be to get the elevator, rudder, tailwheel servos installed and make up the control runs while we still have easy access.

A tad bit of progress is made and, hopefully, more to come with the Holiday weekend. A revised horizontal stab has been designed to replace the old unit with the incorrect airfoil. I've strayed from my norm here and gone back to a "half shell" type of construction. I hope this method will allow for easier set up of the scale gapless hinge but time will tell. With any luck we will have a near finished stab by Monday.
