Welcome to my build series of the Balsa USA Stingray RC plane kit. The Stingray 120 is a great trainer and sport rc plane with an 83-inch wingspan and powered by a DLE-20 RC gas rc plane engine. I will be using a Futaba transmitter system with with Futaba or Hitec servos and receiver. This plane is designed for .80 to .90 2-stroke glow engines, .90 to 1.20 4-stroke glow engines, and 15cc to 30cc gas engines. I will be using basic techniques of building rc plane balsa kits (or at least the techniques I have learned to build rc planes).
In this video I mount the wing to the fuselage by drilling the holes for the leading edge dowels where they connect into the fuselage bulkhead. I also drill and tap the holes for the nylon wing bolts at into the wing bolt mounting blocks below the trailing edge. I show how to use a tap and how to tap threads into the wing bolt mounting blocks. I show how to correctly align the wing on the fuselage to make sure the wing is aligned perpendicular to the fuselage using the "string method". Once I get all the wing mounts finished, I do the final sheeting of the wing. I also make a few modifications to wing mounting areas to make the connections stronger. I use Starbond Thick CA, Bob Smith Industries 30 Minute Epoxy, and JB Weld 5 Minute Epoxy. And I get to use a new tool, I show how to use a Warrior Right Angle Magnetic Bit Holder Drill and Driver Attachment for a drill to drill the dowel holes through the wing.
All of these videos will be placed on a playlist.
I have been building, flying, crashing, modifying, and repairing radio control planes (RC Planes) for many years and enjoy sharing what I do with the radio control plane community, so I started RC Plane Tech channel for fun. I am not an expert, there are many different techniques when building radio control planes. A good way to learn about flying and building rc planes is to see what others are doing, that's what I do and that's why I like to share what I do.
Thanks for watching my channel. Hopefully you will find my videos a little interesting and perhaps fun to watch.

James, love your videos. Just a quick tip. Before you glue in the wood dowels, use a pencil sharpener to put a nice 1/16" to 1/8" chamfer on the end of the dowel that you insert into the fuselage. Makes it easier to insert the dowel into the fuse. Do the same thing to the wing mount bolts. The taper will make starting the threads easier.

@JamesRCPlaneTech 7 месяцев назад

Hi. That is a great tip! I love that one. I’ll try to remember that in the future. Thanks!

@joepellissier2091 8 месяцев назад

Well done. I like the string idea. I would have used a tape measure but it would have been more cumbersome. I think I would have found a way to use T nuts for the wing bolts. I really don’t like drilling blindly through the wing. I probably would have waited and installed the wing screw blocks until I was working on the wing, squared the blocks to the wing, added T nuts and then glued the blocks in.

@JamesRCPlaneTech 8 месяцев назад

Thanks. Ya, I like T nuts better also. With the angles, the blocks would have to be shaped differently, but that wouldn’t be too hard to do. Not 100% happy with nylon and wooden threads…

bel video sempre piacevole ed interessante la parte della filettatura del legno e il suo irrigidimento con CA

Thank you Marco!

@dkrchangar 8 месяцев назад

One suggestion when drilling holes in wood, use a sacrificial piece of wood on the backside of the piece you are drilling to avoid tear out when the bit exits the new hole. It makes for very nice clean cut holes.

@JamesRCPlaneTech 8 месяцев назад

Great tip, thanks! and I was thinking also of soaking the wood with thin CA but forgot. Ug, it was ugly. Thanks again!

I’ve always had the impression that ratio is important when mixing epoxy, so I always use a jewellers scale. Probably over the top, but it’s part of my routine now ;-)

@JamesRCPlaneTech 7 месяцев назад

Thats a good idea. I always eyeball it and there are times when it cures a little faster or slower, but for sure need to get the ratio close, probably having it off too much would impact the strength.

Those “1,2,3,”steel blocks have become ubiquitous.

@JamesRCPlaneTech 8 месяцев назад

Great, they are supper helpful. I have 4 and need to get a few more.

@tomflynn7373 8 месяцев назад

It’s coming along nicely and quick. I know what you mean about taping vs blind nuts. I used blind nuts on the Smoothie and it was kind of wonky because of the angle you mentioned. It moved the wing about an 1/8 back because of the angle. I also like the more simplistic build of this vs the Smoothie, the Smoothie had too much carving of blocks.

@JamesRCPlaneTech 8 месяцев назад

Nice that you built the smoothie. I agree, this one seems to be going together quicker. This is my second BUSA kit, both old kits/designs. I’m finding that it appears that over the years they have made modifications to the kits and instructions that ate not always consistent, I remember the smoothie had different orientations of the blocks depending on instruction book or plans. And there were some other issues. This one is similar, things are not always consistent. But overall they are nice. I wonder if the newer plane kits have better quality control than these “resurrected” ones.

@ToyManFlyer1100 8 месяцев назад

I was looking at that angle...Hmmm...Yeah, you could use "T-nuts", but you would have to "Inlay" them into the mounting wood blocks...That seems a bit cumbersome...Same technique tryna mount Front cowl mounting bolts...Weird angles...Sooo, what I found was Brass inserts that are just screwed in from the back of the holes, sorta like Heli-Coils....Problem is in this case, how do you access the bottom of the Wong mounting mounting blocks, coz I think ,if I remember correctly, at this point, they can't be accessed... Will have study that part of the vid and see....

@JamesRCPlaneTech 8 месяцев назад

Thats a good tip. threaded brass inserts, ill have to look into that.

@ToyManFlyer1100 8 месяцев назад

@@JamesRCPlaneTech ... Well, Thanks Sir...I tryna get back in the hobby after 'bout ta 10 yrs hiatus due to financial reasons...Learnt alot along along the way, but as they say...."If you don't use it, you lose it"....Sooo, I'm watching you to relearn the some building techniques....

@JamesRCPlaneTech 8 месяцев назад

Thanks! I appreciate it. I do a lot of checking what others are doing. Best way to learn.

Great video, I enjoy watching your videos good stuff

@JamesRCPlaneTech 8 месяцев назад

Thank you, I appreciate it!

@gregadondad 7 месяцев назад

Next time instead of string use a length of wood anchored at the tail and then a fixed distance can be established to square the wing

@JamesRCPlaneTech 7 месяцев назад

Thanks. Ya, something stiff would be easier since it couldn’t stretch.

@anthony3D 8 месяцев назад

Super 👍 mais a la fin de la vidéo il manque le test avec la corde. Mais j imagine que c était bon.😉

What's a good RC plane store to go to, I'm in orange county. Thank you

@JamesRCPlaneTech 8 месяцев назад

Hi, I’m not familiar with any in OC, but there is Tony’s Hobby in Baldwin Park. They have a ton of ARFs, some engines, fuels, plugs, etc. they are pretty good. Any if you have a part number you are looking for you can call them to see if they have it. The place is Pegasus in Ontario, I have been in a while. They are similar to Tony’s but they also sell used items and they even had older kits. Hope that helps.
