F4F-3 Wildcat Scratch Build - 1853mm Wing Span

Well guys, my first scale build went OK with the 1400mm version. Everything works as advertised and still waiting to maiden with the return of my test pilot who currently is in college. I learned alot during the process and I kept thinking of ways to improve the design. First I wanted it larger as I think it will be easier to work on and detailing would be more manageable. Second, I want to hide all of the control linkages - or most of them. Stronger landing gear. I also wanted better scaling, from the wings to the belly pan, better turtledeck, fiberglass cowling and improved cockpit. The whole setup will be electric again. I will use the power system for the 1700 FMS models - I believe it is a 300kv. Also looking at their motor mount with improvement to that item as it has experienced some flaws. I will be using the LX Corsair big 3-bladed scale prop - which essentially determined the size. The LX prop is 18-1/2" in diameter...the full scale prop is 9'9 - converting the wingspan to 1853mm or about 73".

best

Hink -

There was a beautiful F4F of around this size done back in the early '80s and was a strong contender on the scale scene back then. Don't remember the builder's name at the moment but there was a full construction article on it in Model Airplane News as I recall even with the construction of the very scale landing gear.

The fella had a bit of a time getting it all together with his skills as a pilot. I saw it fly at a Scale Masters regional near Kansas City. He took off with it on high control rates on the first round and nearly lost the model, the gyrations were so extreme! Had an O.S. 120 four cycle in it - the prop came loose on it in the pits and nearly tore up then too...

Bob (?) Carlsson, I think was his name, maybe with a 'K'.

edit: Found this short reference, maybe a bit large for you though....
"RE: F4F Wildcat

I don't think youll find a wildcat and retracts in that size. In fact I'm about 100% sure. About the smallest is the one offered in Model Airplane news designed by Bob Karlson. It's about 77 inches and you make your own retracts from his plans. Hope this helps."

.............MAN probably has the plans in their services..........

Hey Gnats,

Thanks for the info...I happen to have the Karelson plans from last year and used them as a guide. There were some things about it that seemed difficult and discarded most of it - but his retract drawings are very good. The plans I drew up are based on another model and modified to meet certain needs - like making the wing and retracts removeable - just in case something has to be done. It has worked well on the 1400. I have been finding it easier to redesign the parts, mock them up then go to laser city.

LDM - man you found this thread quick - it is only a couple hours old! By the way - this time around I am setting up all of the cut file sheets for my laser specialist and certainly can forward you what you need or even have them cut for you. Glad to see you here.

I attached a few pics of the mockup - like I did on the 1400. This one did add a few more parts and should fit and look much better this time around.

Tom,

your mock up looks great!
I'm really curious about your real build. That could be an interesting masterpiece.

LD,

I am with you, the Mokis sound great at idle, but sound like you describe at upper throttles. I would love to do one that big - that Fischer 1/4 scale is incredible. But I will say even the Fischer cockpit looks elementary compared to Pepsons.

I have been too busy with work, life and taking a ride in a real Helldiver! yeah baby yeah! - to finalize the cut files - I have the motor mount to finish and I need to fix a couple of formers that were lofted incorrectly.

Landing gear redesign

I made some mods to the gear to sturdy it up and prefitting them in virtual space. This should be better than version-1 with the overhead cam support and struts. Still fiddling but getting closer to cut time.

Ready - set - laser

It has been a nutty few weeks, but I finally got all of the parts digitized and formatted for cutting. Man there are a lot of parts in this thing. Hopefully the time spent with the drawings and mockup will speed the build. Attached are just a sampling of the parts manifest. The time consuming part was figuring out how to conceal the control arms and some of the cockpit details.

Parts

I have most of the 300 or so parts cut. Right now I have to organize and categorize - holy cow what a pile of wood. My cutter guru was short 1/4" balsa and 3/32 ply and should have the balance by the end of next week.

Looks fascinating, Hink...!

Remembering when I first got into building in my youth and seeing all those wonderful parts printed out with such precision on the sheets of balsa. Later, in my late 20s, the excitement of looking at all those parts pre-cut and then the building!

Really a dreamy project this Wildcat.
