Default Wild Hare 35% Edge

Thought some might like to see how the new W/H 35% Edge can turn out if someone wanted to go a similar route. I'm going to be trying out some Extra wings on it later as a Slick 540 conversion.

Specs, please

I had the 33% one a couple yrs back until the smoke pump blew a seal and coated the whole inside of the plane. I dried it out and stuffed a DA85 on it and shook it apart

DL-100 with DL mufflers. 102-1/2" span at roughly 1998 sq. in. Weight falls between the low 24 to mid 26 pound range depending on equipment and engine. I've had 2 of these now. The first with an RCGF 100 that was in the mid 24 pound range, and this one at a touch over 25...I think. Haven't weighed it yet.

This one has a pair of 2,300 mAh A123 type batteries for the flight syestem with a 4.8v 2,000 mAh Eneloop AA nimh for the ignition. All the surfaces are driven with single servos. No need to double up on any of them. Wings are built up, as is the fuse.

This can do any type of flying you want to do with engines ranging from 85 to 116cc's. The amount of control you have with this plane a flight idle speeds is simply amazing.

Great looking Plane Pat, and Bubba, I tried buying a used Yellow,Black and White version used but it got sold out from under me. I think it had something to do with building a crate to ship it.

I really like the looks of the "gunfighter" single-seat canopy compared to the Edge 540T setup. The pictures really look nice. I am sure it is spectacular in person. This plane is very high on my wish list.

I have done a LOT of research on al the planes in this size range. For many years I have compared/estimated flight performance on my planes using Cubic wing loading instead of the standard area-based wing loading. This was especially important when using nicad cells and cobalt motors in electric planes.

Anyway I want to add this Wild Hare Edge has a cubic wing loading that is overall near the lowest of all 35 or so 100cc planes on the market, with the added benefit that it weighs several pounds less than all but one of the planes with a lower cubic wing loading. This means (to me at least) it will float like a butterfly while still having the power:weight ratio to sting like a bee.

FWIW the cubic loading is only slightly above the Park Flier range...

I can assure you that it will indeed float like a butterfly. Ask RTK and Altavillian.

At ultra low speeds and full control throws the plane remains under full control and does not unexpectedly depart from controlled flight unless you tell it to do so. At normal flight speeds it can be effectively used for IMAC. Pitch coupling is quite low in KE without any mixes in place. That surprised me quite a bit since it's a single seat Edge. It holds a line nicely and is not at all yaw "wobbly". All of that with a plane that was a bit on the nose heavy side (8 ounces of nose ballast) for the first flights for conservative purposes. It gets even better with the cg on the center of the wing tube.

I think I prefer the appearance of the single place canopy version over the two seater.

I've always prefered the single place configurations of the all the various aerobats. Something about the 2 place (trainer?) versions have always been a slight turnoff to me although I do own several (models). Same with classic automobiles.. seems I'm just more attracted to the 2 door coupes as opposed to the 4 door "family" sedans.

With that big turtle deck, this thing should do ballistic KE spins. My 33% would stand up with the wings vertical and go around it's wing tube like there was no tomorrow. The first time I got it into that position, I landed to make sure I did not break anything, the 50CC does them like that as well.

I'm very interested in this plane, very interested, like bipes, I have a soft spot for Edge's.

BTerry, what weights did you do your calculations with.

If I do this I'm thinking the following setup

DA100
MTW 75K cans
Mezjlik 25x12 3-blade or Mezjlik 27x12 2 blade (very strong DA100 [&:])
tru-turn spinner for both props
3 A123 2300 cells
AR9100 receiver using the soft switch
32oz tank
8711's all around

I actually have a set of CF main gear left over from the 33% and I have a feeling they might fit this plane

So I'm thinking I'm gonna come in around the 26lb side

Going with a wood prop and fiberglass spinner saves quite a bit of weight off the nose, which is likely something you will want to do if using cans.

You're correct about the K/E spins. It's the easiest plane I've flown to make enter and hold a K/E spin.

Bill,

My spreadsheet uses an average of the actual weights I can find, sorted by engine size/"type" (single vs. twin). Tom's Edge with the DA-85 on a 25 oz canister system weighed 24.5#. On a pitts muffler the weight will be a bit over 23.5# so I used that number.

This gives a cubic loading of 7.55 which puts it in good company, right in the middle of the EF Yak, 2.7m Radiowave Extra, Dietrich 75cc Extra, WH Extra, Pilot-RC 35% Yak, QQ 101" Yak, etc. Of course the Edge is significantly lighter than all of those planes with the exception of the Dietrich and Radiowave planes.

The undisputed king of the hill in terms of cubic loading (when using an 85cc engine) is the PAU Edge (7.07 cubic loading), based mostly on its mammoth wing area and the fact it is several pounds lighter than the Pilot-RC Yak on the same wing area. Incidentally the Wild Hare Giles (7.09 cubic loading) is very close behind the PAU Edge. These two are far ahead of the next group led by the Pilot-rc Yak at 7.29, and EF Yak and WH Extra both at 7.38.

If you look at the same planes using a 100cc twin (on mufflers) things change a bit. The Pilot-RC is the tops at 7.29 followed by the PAU Edge at 7.63, EF Yak at 7.80, WH Giles at 7.81, WH Extra at 8.10, and WH Edge at 8.19.

To give a frame of reference the Aeroworks 100cc Yak is an outstanding plane and is an impressive flying plane. However it has a somewhat smaller wing area and slightly heavier than most other planes in its class. Its cubic loading is 8.6 on an 85cc engine and 8.95 on a 100cc engine, putting it near the "bottom" of the 100cc planes. It is good, but these are "better" in terms of flying light. My friend Dave let me fly his 150cc PAU Edge a while ago and it was in INCREDIBLE floater. At ~38.5# it has a cubic loading of 6.60, which confirms its floating characteristics. It literally floats like a balloon.

All this intellectual property is based on my own research and calculations, and I retain all rights to it. I also stand behind it with the numbers to back it up.

Honestly if you add two+ pounds of canisters, in addition to an extra pound of engine, you might blow the curve a bit. I have no doubt the plane will fly fine but it won't be as good as it could be. I estimate your weight will be about 27.5#, which would give you a cubic loading of 8.83 which is a rough equivalent to the (excellent) AW 100cc Yak. It will fly very well, but not as well as it would if it was 2+ pounds lighter.

Does that cover it? Hope so!

Brett

I can agree with Pat, I flew his first "prototype" and it was very nice. I found the edge to be very stable and have no bad attributes at all. It also grooves very nicely.
