Things are moving along, albeit very slowly, on my Hellcat build! (I got distracted by a disaster of a mini P40)
The blurry pic makes it look cleaner than it is. I had some difficulty attaching the rear bodywork because I installed the wing before, instead of after. This also caused me to install the wing at too high of an angle of incidence, making the thrust angle too negative (for a model this size) relative to the wing. I suspect this higher alpha and wing load will contribute to stalls so I'm thinking about adding vortex generators before her maiden....anyone had any luck with those on similar planes?

As is, the plane balances exactly where indicated in the plans using a 3S 2200mah and 2216 motor. If I add much paint or tape behind the CG, it will get tail heavy which is something I can't afford with my upward tilted wing.
That is turning out so clean! I actually glued the wing on first and then put the molded pieces on so I guess its a happy accident for yours. By the way the hellcat flies, it should have no problems with that slight angle of incidence. Another thing too is this hellcat is so light that it has a really low stall speed.

I’m not a very patient or skilled painter but here is the final result. I am quite happy and not looking forward scraping up the paint on her maiden. I dont have grass at my field out here in the southwest so dirt landing will be rough! FYI, i covered botton surfaces with packing tape for durability and really scuffed it up with 400 grit sandpaper but the paint did not adhere well at all. I should have used Rustoleum, lol.
One trick that did work: lightweight spackle to fill foam board cracks and dents...thin coats then sand down and smear some white glue over it for strength.

Thanks for the vote of confidence. I have a 2:1 power to weight ratio so I’m hoping that if it stalls i can just pitch the nose up and floor it like a 3D plane!

Hi Niez, what is your hellcat all up weight with a 3s 2200mah on board?
That paint job looks great! I really like the paint scheme. I actually used 0000 Steel Wool to sand down my Hellcat. It makes painting so much easier. I am not sure how heavy the all up weight is with the Hellcat but on a 3s or 4s I have way more than a 2:1 thrust ratio. A 3s 2200mah is a perfect battery for the Hellcat. It's my go to battery of choice for flying the Hellcat.

I maidened the hellcat last sunday. flies amazing. super stable. slow stall speed, almost as forgiving as a trainer, yet can get up and go. If any of you are on the fence, you will not regret this build.

Glad it all went well for your maiden! Glad you like it!

I do not understand how this plane has not succeeded
I have made some mistakes but I have finished it
also with a system to extract the wing
forget to paint the cabin before gluing the canopy
Anyway, I plan to repeat it in the future, just like the spitfire, paying more care and more details, correcting errors.
Still, I like how it turned out

That turned out beautiful! Everything from the paint job, clear cockpit glass, and kill marks are awesome! How was the build process? Also, how did you strengthen the wing for the landing gear?

I saw the power pod center the wing and put another piece of the power pod on the back of the wing and a powerful neodymium magnet

two half skewers to hold the wing in front

and the lid with another magnet and another piece of skewer

I think it is possible to install a retractable landing gear without touching the wing structure

Yeah that looks super sturdy for the landing gear. Everything is just so nicely built and clean. I’m happy everything is going well for you on this build because it is sweet!

I’ve never messed around with retracts but I feel like there is enough structural support and space for retracts. Can’t wait to see where this one is headed. 😁
