D25 Delta Update

So, we tested the BL-2212/6 brushless motor. It is a great motor and it may be great on other applications but, it's not what we're looking for.
So we have on the way a 3000 KV motor with 4S. This is a 700 watt setup. This is the ticket to the 100mph goal I set for this plane. Anything above a 100 with this setup is gravy. Stay tuned I will post video hopefully with a speed gun on view to clock speed. Also maybe some boat videos. I just had to build one. Oh! And maybe Control Line electric. You have to keep coming back so you don't miss all of this.

D25 Video Great flight

Success! We flew the D25 this last Sunday and it was a great flight. I am still dialing in cg but, it flew great. Controls were responsive, everything went smoothly. I still have to change the prop. The prop used in the video was from a glow engine and of smaller diameter than requered for the setup we have. So, when we dial in the cg and with the appropriate prop we should see even better flights. So, here's the video. There's a small blooper halfway trough the video as my cameraman let the camera fall to the floor no biggie, more funny than anything! WATCH THE VIDEO!

How To Apply Checkers

Hi there and thank you for coming back! Here I want to show you how to lay your graphics on to monokote film without getting a sticky mess. I say sticky mess because on this case I am using the sticky kind of monokote for the red checkers. If you have been building RC airplanes this might be old news to you but if you are a newbie, you might learn something. So here we go.

First start by selecting where you are going to place your graphics. This works for any kind of graphic you want to layout on the monokote by the way. Then spray the whole area with Windex or any other similar product. I used windex because I had it on hand but you don't have to use windex you can also use soapy water on a spray bottle. Just fill with water and mix in some dish washing soap till you get some soapy water. Don't be bashful, saturate the area with the Windex or soapy water.

Now start laying your graphics. Now you will have the chance to position them anyway you like without them sticking and having to peel them away you can just reposition them.

Keep laying your whole setup.

Start removing the excess windex with a paper towel. Make sure everything is where you want it to be.

 

Now with an old credit card or similar object start squeezing out all the excess Windex. Make sure you don't move you graphics. Continue to squeeze out all the Windex and remove excess with paper towels.

By now things are starting to stick to the monokote. If you have to trim any pieces do it after you make sure they are not going to move.

 Clean up everything, and admire your work!

This also works with iron on monokote. Just cut your graphics, position them as you like, squeege out the Windex, clean up and iron the edges. Hope this works for you! If anybody has any suggestions on how to do it easier. Cheers.

A preview of the 2200KV motor

 Here's a similar plane with the recommended Bl-2212/6 motor

2200KV Brushless Motor + ESC

It's here! I recently ordered a nice 2200KV motor for my ongoing D25 Delta wing project. This was recommended on RCGroups as a better substitute of the 16/15/7 brushless Mega that I used on the first flights. This is a motor to achieve speed. The prop I will be using on it will be an APC 6X5.5 at this setup this should be producing approximately 24oz if thrust with a 11.1v 30C 1350Mah battery. With the decreased weight of the motor and the battery I would be expecting the whole wing weighing at approximately 13 to 14 oz. With this motor we will have a nice thrust to weight ratio of almost 2:1. I bought these at Nico Hobbies. They shipped fast and I didn't have any issues so, two thumbs up! Also the whole thing came as a combo for $27.99 plus shipping which was like $3.00. I have read reviews about this motor and it sounds like it gets things moving. Wanna see it in action? Stay tuned.

Flying Wing Delta

So, I have already started rebuilding my scratch built delta and it's coming along good. As you can see in a previous post it didn't suffer much damage so it is an easy fix. I did uncover the whole thing and will be recovering it. It's should come out at 14-16 OZ this time since I'll be adding a 1350Mah battery this time. This is due to the fuselage being too narrow to fit my 1800Mah battery sideways. The 1350Mah battery is shorter and should fit sideways giving me a wide range of movement to balance the plane with the position of the battery. I also commented on a new motor for it I have an 2200KV motor on the way so with the troubleshooting done on the first try we should get some good results. Stay tuned.

D25 Crash

Well, I had some radio failure and here is the result. I don't really mind at all since there's pretty much no damage. And, since I have made this from scratch, there's nothing I can't fix on it! In a way I'm happy it crashed. That let me know how strong this frame is. I have to say that it is strong and sound. This crash was from altitude at full power, nose first. I wish I hadn't untangled the motor wires as proof that there were several twists on the wires since the plane hit the ground under power. Wing tips took damage because they were balsa. Right now the wing is completely unassembled and uncovered and the minor damages will be fixed. Also since I now fortunately removed all the quirks from the equation of aft CG, radio glitches, I have on the way a nice 2200KV motor to move it along. The Mega motor 16/15/8 proved to be a nice sport plane package for this plane but, this is not what we built it for. The 2200 should provide more speed and oomph. With the right settings this thing will fly perfect on the next try. Keep coming back, next time I hope to have a video to be proud of.

Maiden flight of D25 delta

Here's the video of the maiden flight of the D25. The flight will look erratic due to an aft cg and excessive control surface travel. Will keep working on it to achieve the goal of making a fast delta wing. This is actually the first model airplane I design. It has been a learning experience and I don't doubt more will be learned from this process.

D25

Ok, So I am almost done with the plane. Here I put the fins on still need to set elevons and fix engine to the plane. Almost done!
