Wild Hare 88" Edge 540 Build

Table cloth is a riot!

Some people run out of engines, some run out of headers, some run out of servos. It's just timing. I'll let W/H respond to your other issues except abouty what engine the plane was designed around.

W/H does not suscribe to the "most popular" engine theory. Too many people chasing after the latest, greatest, cheapest engines available for any to be the most popular. What IS done is to have a firewall positioned to where most any engine can be fit without having to cut away and recess the firewall. You want to see someone upset? The person that had an engine too long to fit inside the cowl mounted flat footed on the firewall would be one pi$$ed off sob.

Personally I measure every firewall and engine combo I intend to use to determine my standoff lenghts. I've never had one come up short or long that way.

It only makes sense to measure for your standoffs first, takes 2 seconds to do. I have a WH 35%er and the quality is first rate and Tom always treated me great, even after my purchase. Most arfs usually have a couple little things that aren't quite perfect, but my WH almost built itself

Subscribed.

Thanks for doing this one up Piper. I was/am very close to dropping the hammer on a new 50cc and this Edge was the forerunner. As it stands...I am going to watch and wait to see how yours comes out and how WH sorts out your issues.

Sorry you're having to deal with those issues...small though they may be.

you can't simply measure to the center of the firewall and expect the hub to be centered in the cowl when the fiewall has built in right thrust(as they all do).usually you you add 1/4"to the right as you face the firewall. You simply need to aquire some building skills. Maybe if you didn't spend so much time typing? Not trying to be rude, I'm just saying..........

If you're not trying to be rude, then don't be..

Perhaps the guy is new to building and has a few things to learn, but it's kinda low brow to rip him for attempting to give other guys a decent build thread, isn't it?

It is not the most popular engine people are chasing. Rather, people are chasing the cheapest most popular specs. Most 50cc planes are designed for seven inches from firewall to spinner. With a standard deviation of +/- one inch. Most 50cc motors are in the range of four pounds +/- one pound. The biggest varient is style of flying.

My TOC has a wide set. I'm glad most of the design work was done for me on my Dawghouse Yak. Apparently, Wild Hare has a large target market which leaves little room for specialization. Low price and little specialization leads to an increase in demand for a commodity. But, as mentioned in the build, quality and ease of the build will suffer.

You are being rude. Let's try to be more constructive. I'm glad I have the attention span to read all of his posts.

Thanks for the heads up on the quality control with this bird Pipercub123. I was ready to drop the ball next week and order this plane. I've been eyeballing it for awhile. Now think I've changed my mind. I'm not really concerned about the engine thrust lines. But the poor wing fit is a huge turn off. Not to mention the poor communication from Wildhare. I guess I'll stick to Aeroworks.

pipercub123, First of all I want to thank you for the long and detailed write-up expressing your observations and opinions. You have included many great pictures and good points to ponder, and have obviously done a lot of research.

In order to center the spinner on a cowl when you have a 3* thrust angle on a 7" long motor, you need to offset the aft end of the engine by about 3/8" toward the left (facing forward, or to the right when facing the firewall). 7" x sin (3*) = 0.367". That explains the need for "offset".

When you attached the wings did you install and tighten the wing bolts? I can't see now where you talked about that. I have never owned a plane that had the wings fit perfectly flush to the sides of the fuse without tightening the wing bolts, whether it was SD/TT/TOC/AM, Aeroworks, Hangar 9, Extremeflight, etc. Actually, I think the QQ 102" Yak fit pretty flush to the fuse but it was impossible to tell because the wings fit into "pockets" in the fuse.

The SD/TT/TOC planes come with the firewall set in the forward-most position, requiring the end user to cut it to fit the engine. It seemed like a pain the first time I did it, but all I did was measure the length of the engine, measure the distance from the front of the cowl to the front of the spinner and add an 1/8" or so, subtract this from the first measurement, and then mark this exact amount aft from the forward face of the firewall and cut the motor box. This removed an equal amount from each side of the motor box and left the thrust angles untouched. That whole process was a lot of extra, unnecessary work but wasn't really too difficult once I understood the total concept.

You mentioned developing slop in the hinges of the 40% planes. They actually use a completely different hinge design with a single carbon rod running through the hinge "knuckles" the length of the control surface. Your plane uses Robart Hinge Points, and they are nearly indestructible. You won't need to worry about them at all!

My least favorite operation in building a plane is installing the canopy. I am happy to see the canopy on this plane is already installed. That makes it even more attractive in my book.

I hope this helps answer a couple of your questions. I love to see a good build thread like this and hope you will keep it going.

Brett

p.s. When trying to contact Tom did you try calling him, or did you just drop him a single email? He has always promptly returned my emails, perhaps one fell through the cracks.

Keep the pics coming Piper

[flatspinjim]

Piper, could you post some pics of the wing to fuse fit?

[Tram]

I haven't had any issues with the wing fit on mine...

[flatspinjim]

I've seen quite a few build threads on this plane and haven't heard of any problems. Was curious to see what was going on

[yakpilot]

Pipercub123 and others, I'm sorry for coming off as an *********. Please accept my humble appology and I'll try to keep it more positive. Best of luck with the rest of your build.
