James,

What would the weight be like with a firewall mount? With the double thickness FFF, that should hold real well with epoxy.

Ugh...I hate firewall mounts. I have never been able to get one to last, they just pop off too easy. After trying it again on my last Yak and having the same results I made a promise to myself to never do a firewall mount on a foamie again...EVER.

Default Oh yeah baby

Had a couple of great flights this morning. Conditions were great with little or no winds. I still need a little more elevator and a little less ailerons.

I augered it in a couple of times wide open just for the fun of it. It handled it like a champ, flip the prop straight and toss it back in the air. I will have to get some torture testing video. All that's left is a trial by combat but I am sure it is going to do great.

Sorry guys missed your early post. Yes I have a plotter cutter here. I design RC related products and we cut wooden CNC plans from 1/16 and 1/8 ply, used it last week to cut my new P51D in 6mm depron and was a complete success. Had to change cutter head and laser concentration but its flawless. But back to the topic at hand, let me know when you can and I will run this plane, just need paper measurements or actual templates, I will clean em up and go to cutting.

That sounds great James. I have all the wood templates cut out I just want to do a little more sanding before I cut out the foam. My order from Hobby City has shipped so I may wait until it gets here and send you and Kev one of the mounts to help me test them.

Right on Justin. Did you cut the fuze in half length wise and lay the strip flat in between them? That's what it looks like but it's kind of hard to tell. Will you be adding a Kf doubler on top of the wing or just go with the one underneath?

Seems like some looping thought went into this plane according the elevator design. You ever thought about extending the alerons the full length of wing?

yeah the carbon strip runs through the fuse. Im going to leave the wing like it is. I put a 1/4 in. strip of foam underneath the back edge of the kf. the lighting holes are covered with packing tape. I thought about running the aleirons all the way out but its suppost to be a spit fire and they dont on the real one. I did make them bigger though.

Hey James

Looks great Jack

I would lean toward the nose heavy side, my first flight with it was tail heavy and it was a handful. Maybe 2.25" and work your way back.

I seen where you found somebody to help make plans in a PDF format. How has that worked out for you? Do you have anything yet?

Actually James yes I have and I'm working on that right now. My designer I got is a retired as he puts it "NOTHING TO DO" self taught cad writer who worked for a construction company and did the cad stuff there. Hes a nitro pilot and coming to foam. My design of a certain plane had him approach me to do my designs, and I'm proud to say, yes..now we are working out printing and making sure everything goes on foam nice. But soon as I got a program for doing this and also giving them away...as I said lets do the TCS...I will be glad to help.

In the next day or so, I will start a new Brewster build in the same post..building from my new plans hot off the press lol. I would hope to think my new plans are different then most as they will download in all formats builders like and we have added alot of info on plans for building. The best feature added totally by the plan designer is the painted all fixed up plane..right on the plan print..it just shows you what it will look like when the plane is complete...VERY COOL!!! But not to bore you with my extreme happyness, but whom ever sent this gent to me...thank you. I will announce him on my site soon...lipo profile page.

so not to be a teaser...heres a quick shot of the new brewster plans just laying on floor with the fine details not added yet...as I said Im testing assembly from paper, but should have plans coming out to web by the end of the week.

Well James I may have to build another wing for her, I didn't add a spar she flew pretty till the wind caught her and stuck her nose in the ground snapped the wing in line with the left aileron. Gonna try and reglue it and add a spr to see what happens.

It was about 2 1/4 2 1/2 tosed her without power first and she just floated about 8-10 ft into the wind. So I said ahh what the heck tossed her again same thing so I gave her some power, realized I need to go to an 8x6 then broke her wing. It's drying now, gonna go ahead and try her with a spar if the wind drops tomorrow I'll give her another toss.

I'm back on the TCS mission Did i miss a memo or something...you left LoL Lots of work...time mainly for testing, which is what your doing now, and putting it all together...good foam planes dont fly over night they say.

As far as flying the TCS without a spar, I would think it needs it no matter what..mid airs, no spar, crash landing. On more then one occasion the spars saved the plane....like here..watch these wings baby...thank you carbon fiber.
