I finished all the flight testing I wanted to do on revision 1 and came up with the name for the airplane. It is called the Kshatriya, a hindu term referring to the military elite. I just think it sounds cool.

All I have right now are some 2D graphics to share. I didn't do much to the design. The big thing was giving it a little more wing area by stretching the leading edge forward 13mm. I also pulled the aileron roots forward 6.5mm and changed from a single aileron servo to two. I hope that the stresses in flight during rough pitch maneuvers don't overwhelm the servos! On a single servo model they cancel each other out but on a dual servo model there is a possibility of servo gear strippage or blowback during hard pitch maneuvers. Especially as the ailerons get to be enormous like they are on this model. I also added a few aerodynamic accessories to try and nullify some of the coupling issues I have. I have no scientific reasoning behind the placement or size of the T-can or wing fences. I know the wing fences will give it a little more area to knife edge on, also hoping to tame some of the harrier wing rock on the model. It's a light model, but without any wing fences and that high aspect ratio wing it can be a little tippy at high alpha. One of the reasons I increased the chord was this as well, lower the aspect ratio and tame wing rock. It's not awful on rev 1 but it doesn't groove in a harrier, you're always busy unless you're turning. Which brings me to the T-can....Continue Reading

Well hi again. I haven't got much in the way of text today but I do have some pics. Just today I ventured out an hour away and a local foam plane shop helped me out with their laser and we got a few prototypes cut. One for myself and two for friends who were willing to try it out at cost.

It's amazing what the laser will do for you. The level of detail it's capable of is astounding. Plus it cuts the whole plane within five minutes! We didn't even waste a sheet of foam like we thought we would getting it calibrated to EPP for the first time.

I ended up taking more pages from twisted hobbies book with the wood spar. I'm not sure what they used but I went with basswood and it seems great. I decided to do pull pull controls on the tail surfaces so I wouldn't have to worry about pushrods. Used 1/16 ply for the horns and the motor mount.

Well, it's been a while. A long while.

Not even sure if anybody will see or read this. Anyways, I've matured quite a bit and am working on this new airplane design. I actually haven't designed anything for quite a while, let alone a full blown 3D machine.

So in the 4 years or so that I haven't been designing I've been learning. I've sharpened my flying skill and my knowledge of what makes a good airplane. I've gone from thinking Twisted Hobbys planes and their use of EPP and wood as not high performance to having a Crack Laser and wanting more TH planes. One thought I still agree with my past self on is that man are the TH planes pricey. They are worth it, absolutely. I plane on getting a Veloxity and a 39 inch crack yak before the winter is over. But still, they are costly.

So I decided to sharpen up my CAD skills, or rather learn some from scratch, lol, and make my own design. Of course this isn't worth anything without a means of getting the design to foam. So I've called around and found a place willing to cut my kit. And here I am. I am posting a PDF of the Isometric and of the profiles of the parts. Any readers on here let me know what you think and what you think I might want to change before I get my first plane cut. I will be getting the first prototype cut here in the next few weeks.

The airplane will be cut from 1.3# 9mm EPP. It will use carbon tail trussing just like a depron model, but the wing support will just be a spar, no wing struts. I want to...Continue Reading

Alright well here we are, RCGroups, I got out my graphing paper, straight edge, and a pencil. Time to design! If I can figure it out I will start uploading pics and so on of the plane. But for now I need to design it, at least a rough design. I also have to make a mechanical drawing of my other one that I have put on hiatus for awhile, the Techno. This new one I am gonna hopefully make fly F3P stuff, hopefully. Name for it is gonna be Shadow, at least at this point anyway. Back to my topic, I will leave updates as I go, hopefully at least one person sees this, LOL. If you want to see any of my previous planes or designs on video, check out my youtube channel.
