RE: GP .60 Extra 300s Build
Beautiful planes guys. I think I'm gonna quickly build another one of these and use a gas engine, and i'll post another the build in this thread here, so stay tuned within the next month or so.

RE: Dope cover question
Hi oldbassard, The cloth and dope I've been using for years is all Sig products, which would be the koverall (availble in different sizes), Sig Nitrate Dope (used for sealing the cloth, and I also use it to hold the cloth down on the wood) and SuperCoat Dope which is used for fuel proofing, or adding some color. The sig stuff has worked for me for years, but than some other people use different brands (can't think of any right now) and have success also. The dope I imagine can be sprayed on if you thin it out quite a bit, which would then take more coats to seal the cloth, but I've always brushed it on with good results. For application, I usually apply 2 coats of nitrate on the wood framework, sanding lightly between each coats. I than lay the cloth over where I just applied the dope, and I will now take some nitrate dope and seal the edges of the cloth, and the nitrate I am putting on now will soften up the coats I put on earlier, to make a nice bond. After that, I shrink the cloth so that the weave of the cloth will shrink freely across the whole area (for example over the ribs on a wing). After full shrinking is complete, I then apply nitrate over all the wing ribs to attatch the cloth down there, and after that, its just applying 2 or 3 coats of nitrate to seal the weave of the cloth. Take a look at this thread here I did about a month ago, lots of good info on the application process http://www.rcuniverse.com/forum/m_11181552/tm.htm Its more work than iron on material, but IMO the results are much better, more rewarding, and the covering lasts ALOT longer.

RE: What is the
[quote]ORIGINAL: CellTech Just bought a GP Christian Eagle. Not sure what the so called lite Ply is made of but there is not much of it. No doublers on the front end what so ever. I am almost afraid of mounting an engine because I am certain that the torque will break the nose off. Now for the Rant. The Monokote covering or whatever it is is the worst pile of garbage I have seen in my life. This airplane is more wrinkled than a old dried out Prune. I have used Monokote for decades and never seen anything as horrid as this. My Iron on max heat will not take out half the wrinkles. The covering literally does not shrink. Anyway, after burning holes and unable to make the model any way presentable it has been thrown into the attic. I am done with The conglomeration of Tower/Great Planes. They have destroyed the industry and are now nothing more than a middleman importer of Chinese garbage [/quote] Thats exactly what I've been afraid of, the engine vibration and airframe stress just basically destroying this cheap crap GP uses. Its amazing how kit prices go up and quality goes rock bottom down, but I guess its like anything else anymore. Thanks everyone! Jason

What is the "lite ply" that Great Planes uses for their kits??
So I opened up a great planes kit today, and I went through all the die cut pieces, and the manual said it was lite ply, but it looks and feels NOTHING like the lite ply I get from BUSA or national balsa. Is this is cheap or fake lite ply great planes uses to get the price down or keep the price the same but a break on their part? Jason

RE: Should I Be Worried?
This is like reading reviews of products from people who have boughten and used them, you cant trust half of them. So people say its a piece of junk, some say its the best machine out there. People may have problems because they don't have it set up properly, drained down battery, etc. Think about it, they are not going to put radios and equipment on the market knowing it could be a problem or it is a problem. Now, if the manual states DO NOT do this, DO NOT do that, than don't do it. Sometimes you have to try out stuff yourself and see how it works for you, and not the other guy. I've boughten so many items that had bad reviews, and the product worked great for me. Hope I helped! Jason

RE: Its Official... I Ordered a Kit
[quote]ORIGINAL: turbo.gst Congrats Bill! I hope you enjoy the build process. I like it as much as the flying. BTW the Kadet Mk.II is one of the better flyers out there. It is a harder build than some.( only in lots of sanding / time). You will be rewarded by a great flyer that you can enjoy for a long time..... [/quote] Yep, the Mark II is more or less a builders kit, because there are no laser cut parts (the die cut parts still fit well) and if I recall from my build, there are stamped parts, meaning there are sheets of balsa wood with the part printed on with black ink, and you cut it out with a band saw or jig saw. Remember to have LOTS of sandpaper for this build, not trying to scare you, but you won't get through it without the sanding equipment. Would you consider doing a build thread? Its all your choice but it would really help with all the good and experienced builders on the site to help you if you run into trouble.

RE: Its Official... I Ordered a Kit
As WacoNut said, find a club and get some training. You could also invest about $200.00 and purchase Great Planes Realflight simulator, which will be good for getting you the basics, but don't rely on it completely for the first solo flight, you still need an instructor, but realflight will help you greatly before taking on the model you built, and hey, you crash, hit a red button and you got a new airplane, instead of going to the field with an airplane and coming home with another kit to build. Good Luck! Jason

RE: Making Parts From Kit Instructions?
Sig does a good job of making sure no parts are missing, but in the RARE event, like everyone says, copy the part down on paper or call Sig and ask to ship you a new part of a new sheet that the part is on, they are a good business now so they will take care of their customers. Jason

RE: Sig Kadet Covering ?
For a long lasting durable covering that you can paint to your liking but is ALOT of work, I would maybe take a shot at Sig koverall and dope. Thats how the full scale airplanes are covered (cloth covered airplanes that is) and its a tried and true process that works. Depending on how much work you want to put in and what type of finish you want, this covering is very rewarding when you are done, but it may not be the best for a beginner, but hey, you have to learn somehow. Covered at least 5 airplanes in koverall 10+ years ago, starting to use it again. Jason

RE: Looking for my 1st build.
They stopped making the orginial OS46ax engine I see on tower hobbies, but OS has a new engine that I hear is a true powerhouse. The price is very reasonable if you ask me, and the engine will last you for years. Can't beat this engine: http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXCABL&P=ML Oh and like RV7garage said, you will need a sanding block, some sandpaper, some more sandpaper, and lastly sandpaper. After you build a kit or two, you are going to be the master at sanding, especially because there are parts on the Mark II trainer where its sorta a "sand to shape" deal, so stock up on sanding supplies. It also doesn't hurt to have a couple squares sitting around to make sure your ribs and parts are square. This is a little more expensive item, but it doesn't hurt to have a drill press if you have the space. Sometimes trying to drill a straight hole into a motor mount or similiar becomes a hassle. I wouldn't make it without my drill press [:)] . Jason

RE: Looking for my 1st build.

RE: Looking for my 1st build.
Not having an experience with the aviastar engines, I can't tell you if they are good or not, but I would sure go with an OS max 46 engine instead, quality is much better. As far as whats on the list, you will need for sure: 1. The kit itself 2. For glue, its the builders preferance. Some people use CA glue, traditional wood glue, and some even use the old cement. Epoxy will be needed for higher stress areas such as landing gear plates, firewalls, joining wing panels, etc. 3. The resin isn't really needed, as it is mainly for fuel proofing areas like the firewall and for glassing the wing center section. You could also use thinned out epoxy for that 4. You will need the foam rubber to protect your battery and receiver 5. A FLAT building surface There are many threads on RCU that you can check out that talk about tools in the shop and building for the newbie. Here is a Sig Kadet Mark II build here: http://www.rcuniverse.com/forum/m_6781006/tm.htm All of the sig kits include photo illustrated instruction manuals to guide you through the build, which is really good for a new builder. As people have already stated, its a good idea to check out airfieldmodels online. This guy has all the info you need for building, photos and how to's, its a great site that will help get you going. The kit will have all the wood to complete the kit, landing gear parts, manual, cowl, pushrods, etc. The big things you need to worry about are radio gear and engine. Jason

Sig Koverall Application Process
Hi everyone. I'm just finishing an airplane up and I've decided to cover it with Sig Koverall and nitrate dope. Having not used this covering for several years, I'm a litte rusty on the process, so I just wanted to clarify the standard process for putting this stuff on properly. Ok, heres what I can remember: 1. Apply 2 coats of unthinned nitrate dope to framework (except ribs, attatch cloth to ribs after shrinking the cloth) 2. Lay cloth down, apply two more unthinned coats to secure the cloth to the framework 3.Thin the nitrate dope about 25 thinner and 75 nitrate, using sig thinner 4. Apply 2-3 coats to seal the cloth and fill the weave 5. Apply Sig supercoat and color to finish off the model, or start painting right on top of nitrate dope to fuel proof it Can someone maybe correct me on number 1, I read and watched a video and they both stated not to attatch the cloth to the ribs until after its shrunk, and the reason being so the cloth can shrink the way it wants to, and if its tacked down, it could be "restricted" and put an unwanted warp or twist into the wing. Thanks much! Jason
