36" Edge 540 full fuse with plans and build guide!


Hello all!

I've been scratch building for a few years now and have done over a dozen builds from plans including a number of Tony's builds. So now that I've learned a few tricks of my own I wanted to give a go at posting a build with plans created from 3 views. I caught the Red Bull races a while back and was really intrigued by the Edge 540. So I decided that it will be my first build with plans. I decided to go with the monoblock style build and is made entirely of Rediboard (minus the monoblock).

This Edge 540 has a 36" WS and an AUW of 24 Oz. It flies on a Hobbymate 40 gram 1500kv outrunner with a 9x4.3 prop and a 3 cell 1300 mAh lipo.

Since I just started going for it in the beginning not sure of how it would turn out, I didn't get all the build photos I should have the first time through. So I'm building another one and posting the build info along the way. To make things easier for those wanting to build I'll add links to this first post pointing to the build steps and update as they are added. I will also be updating the plans as changes are made or parts added.

With my first build complete I can say that this is a relatively easy build, and a solid plane that flies great!

Here are the plans! I'll update them if/when any changes are made and also add any additional parts here.


Update: I've replaced the airfoil in the plans to better match the wing. You may still want to trace you own wing for a snugger fit, just be sure the flat bottom is even with the horizontal stab.

Looking good. I'm a big fan of the Red Bull Air Races also, so is my 2 year old daughter. Just curious, What are some of the basic dimensions? Material, WS, length, power plant, ect. That is an interesting outtake on the airfoiled wing, haven't seen something like that before, but it seems like it will do nicely. Keep us posted, and thanks for sharing.

Thanks for the interest!

This build it primarily RediBoard from the Dollar Tree. The pink foam was packing foam I salvaged from work, but 2" wall insulation foam should work as well.

My WS will be 36" and about a 29" length. I think I should be able to bring the whole thing in under 20 Oz. I'm going to try this Hobbymate 2827 1500kv for starters, but I've left enough room to try something else if I'm not happy with performance. I just bought this motor and haven't used it yet so we'll see.

I've got the main wing and stabs all glued on. I use skewers split in half to add strength tot he leading edges of them. Everything seems straight and she's moving right along!

A little progress. I covered the front top of the fuse. I've also started building the removable piece for the battery. I also cut up a 2 litter soda bottle that should work for the canopy. Well, it's starting to look like an airplane!

I got a bit further on the canopy and I'm felling pretty good about it now. I use some magnets on the front, but it fit's in pretty snug right now. Without electronics the CoG is about an inch back from my target or 2.125" so hitting it shouldn't be a problem.

That canopy and nose detail look very nice. I hope you have enough room in the nose opening to mount your motor.

Thanks Eagle, I don't think the motor will be a problem. I'm using a HK stick mount (you can see the mount attached to the motor above) so I just need to drill a hole in the top for the screwdriver access and I should be able to just pop it on. Worst case scenario I can cut the front cowling off and use magnets to reattach, but I don't think it's going to be necessary.

Good to hear, I was a little worried, hate to see you have to cut up something that looks so good. I saw the stick mount in the fuse, but I couldn't make out what it was attached to the motor.

Yeah, I recently discovered these stick mounts from HK. So far they seem to work pretty well.

Thanks Albert....I had to take a break from building all of your cool designs!

I haven't had it out too much yet because of the weather, but my Dark Knight already gets a lot of attention.

Well, I got her covered last night. I used Polycrylic and coffee filters which works well for me. It adds quite a bit of strength to the foam without too much weight. Now all I really need to do is install the electronics and I'll be ready to maiden. I plan to add the landing gear, but depending on weather and where I'm at with building I may just do the maiden flight without them and belly land.

I'll be picking up some paint as well. I expect she's going to fly fine, but I usually wait until it's proven before painting. I think I'll pick up silver and a nice metallic blue and go for the Red Bull colors, although I'm not sure whether I'll go with decals or not.

Wow!


This is looking really nice! I guess I'll subscribe and see how she turns out. I've got a profile scratchbuilt 540 and have been wanting to scratchbuild a full fuse. We'll see. I might have to copy yours!
