F-100D by Col. Art Johnson

Was looking through some of the old plans my dad has collected over the years, and lo and behold, we came across this! He graciously donated them to me, since he said he wont ever fly a jet!

This plane waspublished in the early 90s in RC Modeler magazine...eas designed for a byron fan on a rossi 81.. Im going to use an eturbax from jhh I think..unless someone had a better suggestion?

Other changes will be to add a hatch in the nose area, and to add intake ducting!

Might be a bit before I get to update this, as I will be gathering material...

Btw this will be my first scratch build in 30 years of rc! Only have done kits and arfs before, so I may have some what may be dumb questions as I progress...

Btw yes, I have several years of edf exp. But this wilk be my first "large" edf, as all others have been 90mm and smaller..(but all composite, not foamy lol)

Any suggestions before I get started woukd be wekcome!

Thanks,
Matt

Alright Matt!! another F-100 in the works.
I built a 70mm out of balsa a while back from some old Comet plans. Easy building plane, no real complicated curves.

My Hun is the best handling jet in my hangar. Lots of wing area, comes real smooth and slow on landings.

i'll be watchin this one. I have these same plans and been considering doing an electric conversion my self. Been holding off because ducting to me seems a little intimidating with all the area rules and such. Hope to pick up some things from this. Phil.

Ducting shouldn't be THAT big of a deal, I'm hoping Air Sally ( a damn good fiberglass guy) will give me some advice when that time comes..

The "Saber Dance" was primarily the pre-D models, that had the smaller vertical stab, which caused it to roll in the stall without any control to stop it, but ANY deeply swept wing bird can go into a deep stall like that, the tips stall first, which then moves the center of lift forward, creating what is, in essence, a severely tail heavy condition.. the key? DONT STALL! lol..

I'm thinking I will likely finish this in Flite-Metal, anyone have experience with that material?

Also, found out, my LHS does not carry balsa or lite ply any longer! Is there a good site to order a pile of it from?

Get my balsa and ply from National Balsa. Really good stuff.
I get a bunch of that bargain grade aero lite balsa for not critical formers/parts, sheeting and thick wood I'll need. Really cuts down on the final weight.

I've built two F-100's from the same plans. The first was a full pound heavier using locally sourced balsa & ply. Lite woods really makes a difference.

The ducting is a piece of cake. The F-100 has a huge fuselage to work in.

My F-100 is a pusher but one of my favorites. Always wanted to do an edf version. I will be watching with great interest. I've done plenty of scratch builds. My advice is trust your modeling skills and don't be afraid to ask questions here. There is always lots of good info and plenty of people willing to help.

Well, ordered my balsa/ply from balsausa.com.
will be placing my order for a E-Turbax from Jet Hangar this week as well, I used carbon paper and construction paper, to transfer plan templates to the paper, then to formica for templates to use for the wood when it arrives.. also created my root and tip templates for the foam wings..

I've never cut foam wings before, and was considering having them cut for me, but, with the huge amount of possibilities for scratch building, I think id rather build my own cutter so I can do it myself int he future.. any advice on this?

Thanks!
Matt

Matt, you can make your own cutting bow or purcahse one I made mine, you can buy them for around $50-60 I believe doesn't have to be anything fancy at all, for the wire you can use nichrome or I just use music wire from the hobby shop. I have a variac, have had it for years, some use battery charges, and other power supplies, again keep it simple and it doesn't have to be fancy or expensive, cutting wings is pretty easy, just takes a little practice. Good luck.. W.

Aircraft spruce sells a simple kit for I think 35 bucks ...I have one and it works great. i just use fine wire(not sure what it is as it was laying around the shop)..broom handle with small fiberglass rods for the bow...easy and cheep!

I have that same plan. I was thinking of making it smaller for 90mm edf. But got my hands on a KA F-100. Also, I will have access to a larger F-100 (Usher?) later hopefully.

K&a f100

I also have the K&A F100 that I started to build a few months ago. I never get much time to work on it, but it is a solid and high-quality kit. I love the all-glass jets.

Going with a Stumax 90mm fan and NEU motor with 8S, eFlite 24-46 retracts...etc.

Here are pictures of the base paint before I did all of the weathering.
