“New” 28% Wild Hare Extra 300 84”– Red Black Yellow

[FlyinTiger]

I found that the spacers are too small at only 1/4," so I guess I could get 3/8" plywood from the scrap heap. After the firewall was marked (so I could tell exactly where to put the 0.25" spacer disks), I glued the spacers in place with medium CA. I drilled the holes using the center of the spacers as a guide. Since I already had 1/4" spacers, I decided to make additional 1/8" spacers from plywood to add on, no problem and it gave me perfect spacing.

I don't worry to much about getting the spinner close to the cowling as the right thrust Tom designed into the airframe will be a great starting point in the trimming process. If I need to fine tune any thrust issues I'll use a "throttle-to-rudder" mix that will take care of any wacky behaviors. I'll be going through the trimming process that Peter Goldsmith has outlined and giving everyone the results here in the flying portion of the review...stay tuned for that later on...we've got to finish building her first! I like a purpose built aircraft, and set-up can really make the aircraft easier to maintain as well as more robust in the long run (read "200+ fifteen minute flights" .

Like Tom of Wild Hare R/C suggests, I wicked thin CA into all the joints on the firewall and forward ply area. This is just to make sure everything is secure.

Wow I really like the price on those spinners, not sure I understand what you said about the bevel though? Also do you have to drill it for the DA? AND could you get a picture from the side? I may want one but the picture you posted it is hard to tell how it looks.

I also ended up moving my CG back to about 3 3/4 now I did this by putting my batteries in the turtle deck, I also put some pants on, and all of the servos are programmed, the DA has now about a gallon of fuel through it and I was wondering if any of you have ever switched to the Amsoil right away? CAn I hurt it? I am just sick of this black crap that thi sLAwn Boy goo is spitting out. Plus would synthetic be better for break in anyway?? Going to fly tomorrow, can't wait! Here are a few updated pics of the fuse and pants.

Thanks.

Here's a picture of the spinner from the side. These are pretty nice spinners. Esprit also has them in Carbon Fiber for only a little more money. This shape is more of an "Extra" shape than an "Ultimate" shape.

The bevel is in the rear of the center hole in the backplate. It allows the spinner to slide fully onto the crankshaft extension on the DA-50 without bottoming out on part of the shaft before it rests fully on the place where the bolts will be forcing it (aluminum thrust washer).

Yes, you will have to drill it. If you have a "drill guide" you will have no problem. It would be even easier if you had a drill press...just remember, everything needs to line up so you can flip the prop from the one o'clock position for starting.

How do you get that grey stuff on the inside of the fuse?? Is it a paint??

Dittos to that question- that really is a good look - yet some would complain about the added weight!
I see the backside of the covering at the interior must have been masked off?

[cyoung450]

Yes it is paint, it is a texture type paint you can buy in a spray can at Home Depot. It was time consuming but turned out real good and it is a very light coat it takes just a little to cover. I used primer first they say if you use primer first it won't chip or vibrate off. Don't ask me who "they" are...lol.

Well after moving my batteries around and all this thing is flying great! I got about 7 more flights in today. I am really starting to like this plane....should be great for IMAC, haven't done much 3D yet.

Hope to get some video this weekend.

Looking great guys. I like the spinner also. Conrad if you keep on posting pictures of that textured fuse I'm going to have to do mine. Although I don't know if I have the time or patience as you .

Not a lot got done on the plane today, the small part of my life that doesn't have to do with model aircraft got in the way.

Prepping the servo mounts in the fuselage for the elevator servos took longer than I anticipated. I had to trim back some of the plywood to make room for the DS 8611s that will guide the elevators. Here are two pictures, a before and after (opposite sides of the plane).

I was concerned with not cutting into the underlying plywood that holds the servo in place as a cut would compromise the integrity of the mount and could come loose at the most in-opportune time (like during a "wall" ).

It looks like the aileron servo holes will have to be opened up a bit to accept the servos as well. I'll use the same technique as I did for the elevator cutouts. After the size is correct and I'm happy with the fit of each servo in its mount I will use thin CA to be double sure the mount is secure in the fuse/wing and nothing will work its way loose (remember the 200+ flights the airframe will need to endure?). The CA will also firm up the screw threads for the servo screws so they will stay tight and take abuse.

wow im going to have to pick me up one of those spinners!

[youngflyer]

btw where do you get that paint?

It's time to glue the hinges in! The second most involved process in building the Wild Hare Extra 300.

Here are the items I used to successfully complete the hinging of my control surfaces:

1. Gorilla glue
2. Paper towels cut into small scraps
3. Xacto knife
4. Blue masking tape
5. Glue application stick
6. Q-tips
7. Small container of water
8. Acetone
9. Control surfaces cleaned and prepped

Let me stress the importance of keeping the hinges clean and oil free. Clean them with rubbing alcohol if needed.

My biggest piece of advice is to have everything out and ready to use before starting as the glue expands and foams out within minutes after application. I checked every hole for the fit of the hinge making sure they would go all the way in. Some had to be drilled out slightly at the opening with a 1/4" drill bit. Now, I started by applying the tape over each hole and cutting the hole out with a sharp xacto knife. Then, I dampened each hole with a small amount of water with a Q-tip after pulling most of the cotton off the tip so that it would fit. This allows the glue to foam and expand properly. Next, I applied the glue using a small, round stick and inserted the hinges in - one side at a time.

For the next stage, I moved onto another control surface and repeated the above process while going back to the first and monitoring the glue expansion. I used the scraps of paper towel to wipe away excess glue. As the glue dries, when you move the control surfaces, some of the dried glue will break away...the rest will come off with the tape. I continued with the rest of the control surfaces while always going back to check on the previously glued hinges.

The paint can be bought at Home Depot. I can't remember the name it is something like "Gay Creations" or something...LOL

CYoung,

If you are using the BatShare why do you have two regulators?

[cyoung450]

Now that you mention that I am not sure. Never thought about it. I do have two switches, so I run both batteries on seperate switches, so both switches go to both inputs on the Batt Share then Batt Share has two outputs so I put one reg on each output to the RX. Make sense I always have to think about that one..... so it goes batt to switch, switch to batt share, batt share to voltage reg, voltage reg to rx on two channels.

Am I missing something about the Batt Share device I thought I read the instructions correctly.

Yes I just checked it again, It is how they say to do it to keep a redundant system, 2 inputs 2 outputs, and the regs go on the output side going to the RX.

Conrad,
Did you get any video today? I'm heading off to church here in a minute to do a wedding.I couldn't make it to the field today If you did, E-mail it to me I would like to see it .
