Default Copperhead Aviation Extra Stiffy - Build and Review

Well thanks to an earlier post talking about the Copperhead Stiffy's I went and had a look. I was first intrigued by the price as I'm sure everyone is when they first hear about a $90 foamy. So looked over the manuals, videos etc. and wanted to investigate deeper into what makes a $90 foamy and I found out plenty. These planes are pretty cool for sure. They are loaded with some ingenious features and in my opinion look like they are worth more then double price of your typical flat foamy.

Anyhow I spent a good amount of time on the phone with Tim from Copperhead and he gave me tons of info on what is involved in creating these planes. Call him, you'll be impressed with the features and his willingness to happily answer more then 300 questions . He also suggested the Extra over the Yak to fit what I wanted to do which is indoor IMAC and Freestyle. Well since I'm a fan of things that are better then the rest I decided to take the plunge and get his complete best setup for the money and power based on Tim's suggestions.

Check out the Extra Stiffy [link=http://www.copperheadaviation.com/comersus/store/comersus_viewItem.asp?idProduct=69]right here.[/link]

My setup is as follows:

MOTOR:
Hacker A20-20L
WT. 2.3 oz

ESC:
Hacker X 20, 20 AMP
20 Amp Peek and programmable.

BATTERY:
1500 MAH Polly Quest 20C
WT. 4.2 oz

PROP:
11.47

With this setup above you get 52 oz thrust as tested! That's more then 2:1.

SERVOS:
HiTec HS-55's
Copperhead micro servo leads

RX:
Polk Seeker 6 synthesized receiver
Full range dual conversion synthesized receiver. No Crystals needed!

Anyhow, I'll be posting pics and videos as I go along. Should be here sometime next week and in the air not too much longer after that! If anyone has this close to this setup please post your comments.

hello all, i've flow both of the stiffy's, they are both great flyers. the extra is a little more tammer plane. but it depends on your flying style on which you would like best!!! these are the strongest epp foamies i have ever seen!!! they can take a beatten and keep on flyin'!!!
stlpilot you put you would be running a 11x4.7 prop on the hacker 20-20. ihave one of these and it amps out on any prop over a 10x4.7, they say not to run over a 10x4.7. thats what i'm running on mine. can the 11x4.7 be run???

I just do what the man says, maybe Tim will jump on here and explain why?


It's nice to see such a complete line of accessories for E Flight. They've got bunch of high end accessories and everything you need in stock to get the Stiffy in the air. I really love the name of the plane too, brings back lots of memories from college.

I was also happy to find out that each one of these planes is 100% handmade in my home state of PA. Was very surprised to find out this as they looked like they were factory made.

Hi Dion

Just had my YAK delivered and Tim told me of your build thread. I've flown a friends Extra Stiffy many times with the same setup you are using and it has plenty of power. I'll have to ask him what prop he is using.

Can't wait to get started.

I'll be watching this thread. I just sold a YS110 to fund a "Stiffy". I think it'll make a great first foamy plane. Can't wait to order it and build it.

Well you don't have to take my word for it to wait to get it. These planes are starting to cause a stir in the industry. You won't be finding any negative posts about this plane for sure.

Also I noticed they dropped the price $10 today and have some nice bundle prices with free shipping.

As you can see everything is nicely packed and the quality is typical you would find in a fine made American built product. The snakeskin is professionaly adhered and looks to be very strong. The trim scheme is also top notch as well. Same goes for all the hardware, there is nothing that needs to be replaced or upgraded.

As you can see the ailerons is hinged via the snakeskin. This allows for wide travel and no chance for any air to get between the control surfaces. The elevator and rudder is connected by the snakeskin being sandwiched between 2 piece of depron which it really clever. The v-stab slot is nicely cut out as well for a simple installation and a strong hold.

I think I had the first Extra Stiffy post. Still got mine and loving it. Since I have a great amount of time on mine I have only found one thing that needs reinforcing. I ended up epoxying some fiberglass cloth to strengthen the two wood pieces that glue together for the landing gear. I initially had some serious CG problems, but once I got those worked out the plane has flown like a dream and been basically indestructable. I actually like the plane better without the gear and tailwheel. My tailwheel broke off from a hard landing. I fixed it by gluing in a 2" piece of stiff plastic hose for a new tailwheel.

You can really fly the plane violently I stripped the gears on my Hitec HS-55 elevator servo the other day, so use the strongest micro servos you can find.

Well you're lucky Iowa because I wish this was my first foamy. I can't even count the amount of foamy's I've got sitting in landfills. Price can't be beat when you talk about what you'll save in the long run and that's matters the most. And have no fear cause it's a good one.

Well, I'm happy to hear that then. Some people said $90 was too much for a foamy, but I think these are gonna be "king" of the foamies. Can't wait for some awesome flying.

LETS BUILD IT! Copperhead stresses not to use too much epoxy during the construction process. You will add unnecessary weight!

Here are the building supplies needed for the next few steps: Blue painters tape, 5 and 30 min epoxy (or ProBond or Gorilla Glue), Epoxy brushes, Pencil, Pliers, Alcohol and paper towels.

Place blue painters tape around the motor mount slot in the fuselage. This is to keep the fuselage clean. Press the blind nuts into the firewall. Trial fit the motor mount and trace around the wooden mount with a pencil so you know where to stop with the epoxy. Coat the mount front and back with 5 min epoxy staying in the lines you drew. Coat the airframe motor mount cutout. IMPROTANT!! Make sure the mount is straight. Use a square if necessary. Also make sure there are no gaps between the fuselage and the mount. As soon as the epoxy starts to cure, carefully remove the tape and clean up with alcohol and towels. Trial fit the wing into the fuselage. Place on blocks and adjust the wing till the tips are equidistant span – wise to the fuselage. Mark both sides top and bottom with a pencil so you know where to stop with the epoxy. Apply painters tape around the wing opening. Apply painters tape to the top and bottom of the wings staying slightly outside of the lines you drew so the tape will not get glued to the fuse. Replace the wing and brush with 30 min Epoxy. Clean up excess epoxy with alcohol and let wing and fuse cure.

Next insert z-bend into tail skid and wire down. With 5 min Epoxy, mount the tail skin into the fuselage. Find the center of the elevator and strike a line in the stab only. Lay out your glue area by drawing lines 3/8 of an inch away from center line. Use 5min epoxy to glue to fuse. Measure with a yard stick to check for alignment. Glue the two landing mount halves together with 5 min and clamp. Coat the landing gear mount and gear mount slot in fuselage with 5 min. Insert wire gear. Trial fit the rudder and draw a line on both sides to mark your glue area. Epoxy rudder to fuse with 5 min. Apply Graphics to elevator and rudder.

SWEEET!!!!!!!!
I can't wait to get my stuff in the mail. Worse than a kid at Christmas!

I'm gonna have to put my Fusion on the back burner for a few days Dion! It is all framed up though. I just need to start covering it.

Looks like it's a nice foamy. Good Job.
