Status: offline 		CP - Glad to know I'm not the only one who's had problems getting a Guillows to FF.

I've never had any problems working with wet sheet. I've learned you don't glue it, just pin/tape/secure it in place until it's dry, and also only wet one side to force a warp. Another way is to wrap the sheet around something round - anything from pill bottles (several taped together to form a tube) to full soda cans and 2L soda bottles (being full they don't collapse or crush) to paint cans to car wheels - what ever will give the closest radius. I also like to have the curvature less than the finished curve so it'll rest on the center of the sheet and leave the edges slightly off the mating structure - it's easier to pin the edges down than risk the center lifting slightly and not being glued in place. Trim and glue in place after they are fully dry (I like to give it 24 hr min., and preferably 48 hr. to fully dry...I'm a slow builder, too much of a perfectionist and don't rush anything). Also depending on the part I'm working on, if I have opposite sides to do, say a turtle deck or fuselage side on something like the old Sterling Corsair, I'll wet and shape both sides at once so keep the structure from moving and inducing an unwanted warp on the under structure.

Status: offline 		I have really enjoyed reading this thread. I was building a "G" 190 in south Mississippi toset up as a radio control version Planing on rudder , elevator, throttle and Air.. I had it framed up and covered with silkspan. Had filled in between the longerons with 1/32 and sanded well . I was still thinking on power and what radio gear to use. But Katrina got there first. I had worked on it when ever I visited my brothers house. I will start another one now when I get my board cleared.
Will change the airfoil; use plastic bottle material for the cowl and canoply. i may go brushless or throttled 0.20, or 0.49. This thread has been very helpful.
Thanks,
John J. Smith [RCDOC]

Status: offline 		That's good info, I think patterns could be developed to make forming a fuselage from 2 major sheets doable, even the canopy sides. Once I get familiar with this style of construction, then it's goodbye sticks and stems, unless one of those psycho-masochistic spells strikes again!

Status: offline 		HI RC DOC! Sorry to hear about your work that got washed away. If you saved the plans and have plenty of #11 blades, you'll have another one going before too long. I just divided up the cutting of parts into a few 1 and 2 hour sessions so's to not get too burned out.

Status: offline 		The wet sheet approach works very well with the Guillows kits. You do have some amount of cutting and splicing around the compound curve areas and I used wood glue so I had time to "work" the sheeting onto the fueslage. I did this with my Guillows Zero and will post some pix later this weekend. Around the firewall I coated the inside of the sheeting with a thin coating of epoxy resin first, then rubber-banded and pinned the pieces into place. The epoxy works both as glue and fuel-proofing, and I can't imagine trying to brush this stuff in place afterwards.

If you beefed up the longerons and formers I'll bet you could leave out the spars entirely on the Guillows kits. Might need a few around the compound curves to glue down the sheeting, but that would be minimal. I used 1/32" sheeting on my Zero but will use 1/16" next time so I can sand it afterwards. (yes, I will be doing another Guillows conversion - probably the P40!) The 1/32" sheeting is amazingly flexible, but there's limited ability to do any serious shaping without sanding right through it.

Status: offline 		CP - The Ace Simple kits use the "two slab side" approach and build quickly. Not horribly scale, but with the right paint job and finishing they look pretty good - especially in the air! I'd bet they'd look better if you rounded the formers slightly. Hmmm. Might need to whip out my F4u plans and try a rebuild this winter...

Status: offline 		Hmmm .... lots of food for thought here!

1/8 stringers or 1/16 stringers ... to sheet or not to sheet, that is the question ... beef up formers, or eliminate some ...

While all of this is mulling around in my mind, and I'm watching this thread intensely, I'm starting my Spitfire build. I'm taking pics all along the way and will post in a new thread.

1/2A makes it so a guy can try alot of different things without spending half his pay check.


And ... you can build it all in a small area. I have a cubicle desk at which I can sit and relax, and the build doesn't take up all of my workshop. I like big planes, too, but I quickly run out of room for them, building or storing.

Actually CP, I'm not a 1/2A lover, I just like R/C in general. If you saw my garage, you would think I'm insane with all the various sized hydroplanes(34" electric to 62" gasser), an under construction 54" Sig Kadet Jr and plans for other planes ranging from a 30" Electric Northstar to three big gassers(a 80"+ Katana, a 68" Pitts 12 and a 70"+ Extra 300), in addition to my two Guilow's kits. Each has their own challenge, and I love a good challenge. The biggest challenges (for now) are time and money , but you know how that goes

Status: offline 		Well, outside of putting on a second coat of paint on the cowl, this one is done enough for me. I weighed the plane with all equipment prior to covering, and it was 10 ozs even. After covering and some paint, it weighs 11.4 ozs now. I wouldn't want a plane this small to weigh much more, it is comparable in wing loading to the MUSTANG OUTLAW. I have to make up some fresh 150 mah packs, and then it is time to flight test this little fokker.

How'd you decide on the size and throws of your ailerons?

Status: offline 		Dig it - Looks like another screamer! When's the maiden flight? Since we know how it looks we'll want a complete write-up so we know how it flies.

Are you really 11.4 oz RTF? If so I'm waay impressed!
