Nice Pics, you do nice work Gerald.

I put some pictures of another wood fuse 2M design on my webpage if anyone is interested.

It's Scott Dunphy's new design the TITAN .
As you can see, its a widebody design. Balsa fuse. Foam attachments. Glass canopy and chin cowl.

Very nice indeed.
I will be starting 2 of these after the holidays.

The plane is still being tested and evaluated by Scott, but he has graciously allowed me to get involved in the beginning stages.

Gerald,

thats a good lookin airplane. sent you a paypal for the formers can you tell me if you got it please?

thanks

Hey GW,
The Titan looks very good. Is the stab just a flat plate or is it very thin? can't tell from the photo.
Keep us updated
thanks and Happy New Year!

Its a modified eppler airfoil , or very close. Almost a 168, but slightly thinner, . Its a modified version of a well known pattern aircraft airfoil and moment.

Its fully symmetrical, and fairly thin, but not as thin as some of the airfoils of the past 5 yrs or so.

Looks alot like a Synergy 2M to me, At least thats the closest resemblance to anything else out there right now.

Stab is one piece design, Plug in wings.

I got my stab finished today. Going to start the wings tomorrow. Hope to finish them by the end of the week.

I will post some pics on the progress as I go along.

Hi Patternjunkie
Can you tell me if Scott intends to release the plans for his Titan once he has finished developing it?
If so does he or you have any idea when this is likely to be?

Mike

Im not real sure of his plans right now. There are probably 5 being built right now. All prototype stuff. But, he is real happy with it so far, and Im sure will be offering it to whomever wants to pursue building one. He made a statement when I asked about publishing his pics of the Titan, and my building of one he stated to me :

"I'm in this hobby for everybody to enjoy , I have no secrets ."

Great guy ehh? Sure enough!

Where can I buy a set of ribs for the T2000 wings (laser cut preferrably)?

no where yet. Were working on it this spring. Hopefully!

I have 2 more laser cut sets of the Typhoon 2000 formers, if anyone wants them. $40 delivered to you. It includes all the formers on the the full former sheet, and a few extras cuts that will be needed elsewhere( total of about 30 laser cut parts). Anyone that has cut one of these sets by hand will know this is a great timesaver in building this plane. The only changes made from the original Typhoon 2000 was to slightly round the bottom of the fuse ,for a better looking plane as well as building ease.

I ordered 4 sets that were "spoke up" for and only 2 modelers came through with the funds.

Thanks to those who followed through though!

The other 2 are available now . .

I am not in the business of selling laser parts, as Im sure many of you know, I just wanted to make these available to the individuals who wanted to build this great 2M plane.

I just received my set of formers from Gerry and they are A-1 quality. Nice, light contest grade balsa.

(No charge for the testamonial, Gerry!)

Dave

glad you liked them

OK
Lets see some construction pictures of the T2K's you all are building with these laser cut formers.

how much would it cost to build the typhoon 2k model?

besides engine and electronics..

ok i found this page:
http://www.gatorrc.com/kits/typhoon2000.htm

looks like id need the formers for the fuse, plans, canopy, cowl, foam cores, what other wood do i need for the fuse and for the wings,stab,rudder?

im thinking of building this airplane, it would be my first pattern airplane and also first time building with foam core wings..

please advise! im really thinking about this plane for my next project

10 pieces of 1/8" x 3 x 36 contest balsa for the sides and turtledeck.

some 1/8" lite ply for a few supports that are not laser cut.

For foam wings. about 20 sheets of 1/16" x4x36 contest balsa

Where are you guys getting the foam cores from? I guess Gator's pricing is pretty steep.

Gerry, do you still have some laser cut formers? How are you building the fuselage, are you using a jig?

I am looking to build a new pattern plane for the next season - it seems winter will extend around here.

Foam cores fom Gator RC. Bout $100 for the full set of foam.
The plans show how to build wing and stab from Balsa if thats you liking.

I have some more laser cuts being done now. Let me know if you want a set.

I use a gator jig for the fuse. Check out my webpage listed below for some pictures of the Typhoon framing.

I have also built my Titan in that same Jig. I think its the best fuse jig ever. Perod.

GW,

What are you asking for laser cut parts? Do you have anything for the Typhoon 2+2?

Larry

MHester, I've thought about creating balsa composites for parts of my planes before, but CF cloth is incredibly expensive. Have you ever tried Kevlar cloth? Granted, it's not nearly as cool looking as CF, but would Kevlar or even S-glass fiberglass cloth perform the job at a more cost effective price?

snsmith-

I'm sure other people can give you better info than me but,

Carbon fiber is the stiffest, and therefore great for strengthening something to make it more resistant to flex.

Fiberglass is not as stiff as carbon fiber, but still stiffer than most things such a balsa, so it does compliment balsa for stiffening/ strengthening. Its more "springy" than carbon and will result in more weight to acheive the same "stiffness"

Kevlar tends to be more for reinforcing for ultimate loads, as in it just wont give up completely, unlike carbon which will snap when overloaded. So kevlar tends to be good for reinforcing something to prevent if from breaking apart, but lousy for stiffness.

If i were reinforcing something to make it stronger and stiffer and didnt want to pay for carbon than my next choice would be fiberglass. I would reserve kevlar for something that was impacted where ultimate strength was key not stiffness.

Now these are only my opinions and someone more knowledgable than myself may very well feel otherwise. I think MHester was a good person to ask.

Hmmm...I thought Kevlar had near zero elongation before failure, which ideally should make it a good stiffening component in bending. I know fiberglass will stretch and I'm not sure about CF. I guess I should dig out my engineering books...

Just looking for ways to make some stiff composite structures without breaking the bank...Kevlar cloth is ~1/3 the price of CF cloth. I might just have to buy a yard of it and see how it performs...I was hoping someone here might have tried it before.

You oughta look in the composites forum, i'm sure if you do a search you can find what you are looking for. I hadnt heard that kevlar had near zero elongation before failure, but if thats the case then you would think it would be good for stiffening, wouldn't you?

Although, kevlar is used for things you would think would need flex. Applications such as pull pull cables, bullet proof vests, and containment shrouds on jet engines. I can tell you that kevlar is hard as hell to cut with scissors and CF is easy.

Anyway, i would look in the composites forum, you will probly find your answers there.

Good luck

JetA, good idea. I didn't even realize there was a composites forum (been away from RCU for awhile and just now getting back). Yes, Kevlar has near zero stretch which is why it makes such good pull-pull cables. Flexibility and elongation are not necessarily related properties. Perhaps I'll raise the question in the composites forum...thanks!

I posted some more pictures of the Typhoon 2000 on the webpage, as well as many new construction photos of my Titan.

The designer of the Titan is entertaining the idea of making the plans and parts available to the aspiring builder. I think it would go over great, as there seem to be many balsa builders still out there. I will keep you all posted on this if he decides to go this route. I truly hope he will. I have no idea how it will be marketed, that will come later i guess.

A few things I have noticed about the Titan, now that mine is framed up:

1. It builds light. No extra measures taken to make it light, there is just not many parts to make it heavy.

2. The engine bay is HUGE!! Maybe a zdz 40 gas in the next one?

3. It does not cost an arm and a leg to build. You have a balsa plane,that is lightweight, no noise enhancing fiberglass, and has the look of the European designs costing $1000+

4.. ,,and ,,Its dang pretty! at least to me
