Thanks Chic.......I do remember your references to to the Advenger and Birdog and the Bobcat........I can only keep up with one project at a time......and even at that, I spread myself too thin..........in reference to the washout, is this for the Bobcat or the Advenger?.......I do know that it is 2 degrees pos at rib #26 for the T-50............as far as the engines used ..........I peronally will be using two OS 160 Gemini 4-cycle nitro engines.........she will perform just fine on as small as 120's...........as far as gas is concerned......I have only the input of other builders on this thread...........Murphy is using the G-26's........send him a post........he can advise you there..........back to the washout problem Chic...........you can actually induce the necessary washout in you wing panels.......it's no different than removing a warp from your wing.........in this case, you are inducing a controlled warp at the tip of the wing.......the Don Smith wing used a jig at the rear spar to evelate it gradually from the wing root out to rib #26.....so the 2 degrees of pos washout was built in..........but, something happened on my right panel........it ended up with "0" washout on that tip....and 2-degrees on the left.........but not to worry!........my friend Ross said if it's made of wood.......it can be warped, 90 degrees if necessary......but remember, we are only looking at a measly 2-degrees..........so, we set the wing up on a table and level it at the center section.....then we weight it down and install incendince meters at the root and both wing tips............the meter reading at the root should be "0"..........my let wing panel meter indicateda pos 2 degrees washout............but the right panel was at "0", same as the root!.......so, we addeda long bar to the meter and clamped it at 3 degreesafter wetting the leadingedge planking, top and bottom....and.....the front and rear spars with a mixture of water and amonia...........after 24 hours.........we now had equal washout in both wing panels.......................in reference to your paint scheme, I love the desertcamo used on the RAF Bobcats............I think I may have a photo or two to send to you....if not I think I have a friend who could supply them.................Chic!.......get back to work on your Bobcat!........I will help in every way!

I have all the faith in you Rich. The parts and pieces really look good as do those twins. Happy Thanksgiving to all of you guys.

Dentist says I can't drink anything through a straw for a few days. But Linda is going to shred some turkey for me and whip up some mashed potatoes. But I also have a bad tooth on the other side that's gonna have to come out eventually, so chewing anything is problematic. The tooth I had pulled today was on the good side!

Thanks so much Ken!..........and a "Happy Thanksgiving " to you and Joyce!!!!!

Great thread guys! The detail on some of these aircraft is outstanding. I understand the starts and stops of the builders here. I plead guilty also. I finished this RCM plans-built T-50 about 7 years ago and have yet to fly it. O.S. .30 fourstrokes for the push.

Hey Rich: Glad to see you're back on the Bamboo Bomber! Absolutely great work..."You da Man" Thanks for sharing the updates. I think you will like the OS160. I had one on a 1/4 scale Cub...never missed a beat!

Dauntlessuk: My Songbird weighs in dry at 32 pounds...25 pound wing and 7 pound fuselage. Of course everything is in the wing except the rudder and elevator servo's. She's still a hanger queen however...(insert lame excuse here).

Wishing you all a Great Thanksgiving!

Thanks so much Murf.........I made a promise to my faithful friends that I will make a real effort to stay with it to it's completion by August...........they said, do you mean this August?

Happy Thanksgiving to you and family.....

.....Very nice work Bob.........I think I have the 1964 issue of RCM that featured these plans...........I purchased a set in 1995 and made plansto build her and then I discovered Don Smith had a 1/5 scale version...........I originally planned to scale the RCM plans up to 1/4 scale............then decided to just gowith the Don Smith plan.........If I can rememberright, the RCM plan made no reference to the cowl construction and I notice that yours looks to be of fiberglass or thin alum........they look great and theattention to detail is very nice.........also, what did you use to build the canopy frame?......that also was not clear on the RCM plans...........and, what does she weigh?...........when I saw your photos it occured to me that I had one on file but dont remember where I found it.....I have been collecting info on this plane for years, which reminds me that I have a copy of this same plane .....also in the Canadian Crane color scheme.........in fact, I thought it was yours, but it turns out that it is not...........I will include a pic so you can see how close they are.

.....Bob, tell us about your project........like, what inspired you to build the Bobcat.....the color scheme........how long did you spend on building her...........what kind of problens did you incounter along the way?

.......and.....welome to this littlegroup.

.....Mike.........did you survive the holliday?..............How was the turkey!............I had a great time, spent Thanksgiving day with close friends......hope you did too.....

Yep. Linda shredded the turkey in her food processor and chopped some carrots extra fine. We also had mashed potatoes and stuffing. Everything was soft enough that I was able to eat without any trouble. The pumpkin pie's crust was a bit difficult, but I was able to wolf everything down.

....That's great Mike.....thanks for the feedback.............now you need to get in shape for Christmas dinner!!!!

Rich.

........I have no photos or info on my build, but I will as I progress from this point onward......in the meantime, I will intertain you with some reference mtrl of the real thing..........I know you will want to file some of this in your folder Murphy...........

......Okay you guys, I'am not the only one building one of these birds..........but it seems like it.........my friends have now refered to it as my life long project....I guess their right!, I did start on it in 1995.........I started out to just build it plain and simple........but the further I went into it and the more reference material I gathered the longer it was taking to the point that I could no longer project a completion date..........the new roll-out schedule will be Aug 2013.........and, you guys are witness to the fact that I am really trying to meet my deadline..............so, help me out here, sometimes I need encouragement..........write an article about your project........post some pic's.........or, just say......."HEY"...........wahta-yall-doing out there............(Texas Talk)...............while I'am waiting to hear from y'all, I will post a few more pic's....

......These engines will be mounted vertically opposed rather than horizontal to take advantage of of the dummy engine cylinder arrangement to allow for proper cooling..........a few more pic's for your viewing.

About the same time I started on my book! Maybe we'll both finish at the same time!

Rich: What are the cooling baffles made of?

And just to keep you on track for the August 2013 completion date...I'll match that with a maiden flight.
Mike, do you want to join in with the completion of your book? August next year seems like a good target...
M

rhsmrt50

......I was wondering when you would ask?............the cooling baffels and the air scoop are all made of Crystalblank paper.....some people call it poster board......it is about .016 in thickness and is great to work with...........the secret isthe stiffining of it after the part has been made. you know that CA will harden wood.....it will also harden paper....in fact so hard that you will not be able to cutitwith anexact-o-knife......the CA soaks all the way thru thepaper and seems to displace it's every fiberwith a plastic like consistancy and feel......I have found that if the part is to have a paint finish it's better to coat the paper on the opposite side as it tends to produce an uneven surface that requires sanding to smoothing it for paint, and that works,but like I said, it is very hard....Once the part is made andhardened alight sanding will help prepare it for priming and paint....I am using Nitro fuel, so my choice of paint is Aerogloss......but they only produce the clear, sanding sealer, balsa filler coat andthinner........I primed the surface inside and out with the sanding sealer, my favorite.........I used three coats of sealer and finished it off with SatinBlackLusterKote spray paint. Try experimenting with this method on test peices ofdifferent paper to seehow well it works.........but besure to lay it on a non stick surface such as a sheet of teflon, that backing paper on most peal and stick decals........also an old teflon skillet will work.............so, now for a few pic's to better illustrate this procedure.

Rich: That method works great. It's light and strong. That's how I made the rear hatch on my T-50. And it takes primer/paint very well. When I made the hatch, I used some CA that I got at Walmart...very cheap. Another reccomendation...do it outside, and preferably with a bit of wind. The vapors from that much CA are intense!

....Your right.....I forgot to mention that.............I also forgot that we talked of this paper process earlier in the thread,.....well it dos'nt hurt to mention it again......this time on a different subject.
