FTScratchBuild-Intermediate

This Flite Test scratch build airplane was inspired by Bloody Mick's FUNBAT and the Sig Wonder.

The FT Bloody Wonder is the newest addition to the Flite Test Swappable Series!  A series of scratch built planes designed with an interchangeable fuselage.

The Swappable Series currently consists of:
The Nutball
The FT Flyer
Delta Wing
Baby Blender

 

The FT Bloody Wonder features a swappable fuselage that is interchangeable with the other airplanes in the Swappable Series! 

This combat flyer is capable of vertical take off, it can fly off the 24gram motor setup on previous swappable fuselage or you can upgrade to the NTM Prop Drive Series 28-26A 1200kv / 250w motor

One of the unique designs of this scratch build is the rounded aileron wing design. Created the same way that the Baby Blender wings are made, the rounded ailerons provide great lift! 

In case you missed the review of this plane you can check it out here:

FT Bloody Wonder Build Plans Available Here:
FT Bloody Wonder-Swappable - 1 of 2
FT Bloody Wonder-Swappable - 2 of 2

TIP for printing the plans: 
To print "tiled" use Adobe Reader X and in the print dialog select "POSTER", select "Cut Marks" and make sure "Tile Scale" is 100%. Then overlap and tape as required (after trimming the top overlapping edge). 
(Thanks youtuber larrybarrick for this suggestion!)

This is my first (so I'm buying everything). Total came to just about $100. Most of that cost was the transmitter (6ch, ~$28) and the shipping costs for the transmitter and battery from Hong Kong (from hobbyking.com ~$40). If you can avoid getting anything from Hong Kong, then it will all be much MUCH cheaper.

I don't know if you got an answer yet but the foam board is 2 bucks and the hardware and electronics can be as little as 30 bucks plus your tx and rx. I have about 40 hours on one and I love it in all kinds of weather (except rain)

Just getting ready to glue my fuse parts together and notice there is no reference as to where the notch on the back piece should be cut. Where does the back of the fuse stop at the front vertical notch? The fuse plans just show a C channel, no notch.

I'm going with the front of the Vertical tab but a quick plan correction would be nice.

I just finished building mine (first swapable AND first plane evah!!) Now, the electronics need to arrive (by the way, does anyone else think that the hobby king site is the WORST SITE ON THE PLANET??!?!?)

Quick notes about my build
-Took 4-5 hours! First of all, those plans don't have any measurements. Try figuring that out when some measurements are in centimeters and others are in inches
-Other than that, not too difficult. Taking the foam out of the grooves was harder than expected, but that will come with practice
-Beveling the control surfaces was harder than expected too. You really need a really really sharp blade.
-THAT HOBBY KING SITE IS TERRIBLE

See ya'll in the air soon!

I'm looking at getting started on building this (my hardware is in the mail) I've noticed that there are no dimensions on the plans, also that the rear section of the fuselage doesnt have the notch cut out of it like in the video. Is this something that we can just wing? or can the plans get updated by someone who knows what they are doing (its my first scratchbuild, so i really dont know what i'm doing lol)

Just finishing up my Twin Twirl I think I'll build one of these next. In the video however, it shows you opening up the hole in the servo arm with a Xacto knife. Don't do that. Instead, chuck a spare piece of the wire that you intend to use that has been cut off into your drill and use that to drill the hole open to the exact size of the wire. No slop solution.
Also, a little whetstone can be bought for a buck to put the edge right back on your Xacto knife. Don't have to replace them so often that way.

Good tips! Thanks. It'd require some skills to sharpen a razor, though.

MrClean November 3, 2012
its an easy skill, lost in a disposable age BUT it costs nothing and keeps paying back. If I weren't cheap I'd build my planes from Gold instead of Dollar foamboard.

Unfortunately they'd fly just as good!

Just finished building my airframe. I cut the notch in the back at 2.5 inches. It looked about right but I don't know for sure. I built this one out of black $tree foamboard. Looks pretty decent but I think the white stuff is better overall. I just need to add servos, control horns, music wire and glue on the vert stabilizers to finish. Still need to do most of that on the FT 3d too...Can't wait to fly these two. Thanks again FT.

Hey guys, I'm from Brazil I already built my Bloody wonder, and i'm plannig to buid a new one, but I still have some doubts about the foam that Josh uses in the video
I've built my first in pure 5 mm depron

but it is fragile

and i want to know if the foam in the video is coveres by paper on both sides
and if we need to peel of any of the sides during the build.

My first coment so hallo to All :)
mtperes... i'm building my planes from deprom 4mm but i use PVC foil to coat it (outside).
First i was also thinking that it will make my plane havy. I 'm jast finishing to build my BBlender.
but in total it is now without battery ~390grams (including landing gear, servos, engine, reciver, and 20cm of thin aluminium pipe to make it more stable).
Foil that i chose is realy havy, so now I bought now some :
http://www.hobbyking.com/hobbyking/store/__22980__Wing_Tape_45mic_x_45_mm_x_100m_Wide_Red_.html
and this one is way thiner and way more light, so now i will coat my planes with this one :)
And using tape is for perfect for bending wings, without it depron brakes.

How i make it is easy. I cut out depron part, put foil on it and then with heat gun activating glue on foil, if You do it right then PVC is realy soft and melting with depron to one. Looks great because my foil is red, and it makes everything way more stable and wather prof.

Sory for my english, but i'm from Poland (living in Germany and working in Netherlands :) )

Chad, love the videos and the swappable series. However, I've noticed that what you show and what the plans show aren't always the same ie. the rear fuse doesn't show the step where it fits into the front part.

A noobie question, do the Hobby King motors come with the motor mount and the other stuff that is required to mount the motor?
Log In to reply
kah00na May 24, 2013
Most of them do. Look at the extra pictures on the motor you're looking at. You can also try to look in the "files" section and see if someone posted a picture. Another thing you can do is post the question in the "Discussion" tab and someone should reply with an answer for you.

hhins May 1, 2013
A couple quick questions before I build...

-- Has anyone tried using two aileron servos vs the center/single servo?

-- Does the lower half of the vertical stabilizer need to be so long, it will make adding some landing gear a bit more tricky as it'll need to be taller

-- Any flight videos with a blue-wonder/similar motor? I won't get my upgraded motor for a while.

Thanks!

kah00na May 24, 2013
Sometimes the location of the servos have to do with weight distribution. If you move it back, you may have to make some adjustments to where you put your battery, ESC, and receiver.

This is the 1st Foam board build I have done, my total build time was 5h, 3h consumed by cutting and measuring. the actual assembly was done in 2h and quite a pleasure.

Will post my Maiden flight as soon as it happens (August 2013).

Thanx for an awesome build.

What is used to hold the prop on the shaft? I recall them showing some rubber band that held it down, on crash the prop would give.

I use a PropSaver on my motor shafts. I use either a 3mm or 3.17mm depending on the size of prop shaft you have on your motor. A rubber band is used to hold the prop on the PropSaver. I get mine from headsuphobby.com. The PropSaver and use of the rubber band makes it possible for the prop to move therefore giving the prop some protection in crashes.

I love the PropSaver! I keep busting the Oring it comes with so I took some small hair rubber bands from my daughter, with her permission of course ;), they can be bought at $tree for $1. and you get like 500. Keep em' Flying! This Bloody Wonder is a blast to fly!!!

I use an o-ring about 1 inch in diameter.... holds up better than rubber bands but still allows the prop to pivot and not break prop

finally got to fly it! I used a grayson hobby disposable foamie motor combo for $19.99 that i had on an old foamie. i got the sport not the 3d motor. its a 2208-14 with 1450 kv with an8x4 prop and an 800mh lipo. flies great! power combo runs cool! had to add alot of weight in the nose (3 sinkers behind firewall in pod) to offset extra weight from the elmersboard vertical stablizers to get it balanced. I balanced it about 2-3 degrees nose heavy and flew it in moderate wind and noticed that going into the wind the tail wagged like a happy dog. don't know why, but I think that I'll try to iron the leading edges of the v. stablizers to a sharper edge to help itcut the air better. (any suggestion?) the plane flies nice with conservative throw on controls, I even had my son ,a slightly experienced beginner, fly it in that wind and he handle it well for about 2 minutes, then he got nervous and I took over as the wind was gusting up the the point that the plane was flying backwards ( about a 20mph gust) on my final approach. I landed it.
I might swap out the elmers foam for dollar tree foam on the stablizers to lighten up the rear and add a rudder servo. might just throw on a speed motor pod to balance it out with a big motor instead of dead weight and run it low on the stick and long on the battery.
overall its a great plane design.

Just finishing up the nutball as my scratch build and learned a lot about building foamies.

With all your great swappable designs, it looks like this will be a winter of shuttling between my building table and Dollar Tree.

I'm an RC noob so hoping the nutball is as forgiving as advertised. The electronics are on order from Hobby King so stay tuned for a maiden crash report in a week or so.

More full-throttle, prop- breaking "landings" than I care to talk about.❇. Contemplating building a pusher to get the prop out of harm's way. Likely Experimental Airlines Axon.

I'll tell you what I built a specter v2 from Ibcrazy via fpv labs.com also there is a great write up on here just search it. Got it in the air and give the control to my older brother who has never flown and did I great. It's fast it's slow it's a pusher and the throws on the ailerons are gentle so it won't twist out of control lol. Here is a video of mine sport version with a micro jet v3 and 2200mah 3 cell from a few weeks ago. http://youtu.be/1EZEVbyuLqg

Looks like a build I can handle. Does it fly OK with just rudder and elevators. I don't have enough thumbs or brains for ailerons yet. Can you recommend a motor and prop combo?

Thanks.

lol it is just bank and yank BUT i put my ailerons as my rudder stick. the ailerons are not big enuf to get you into trouble and that plane seems to self right its self more so then not. motor and esc, here are a few links keep in mind i have 2 versions one for crazy fast flying and one for fpv. fast flyer has 2200 kv on 6x4 prop 30 amp esc. second is 1200kv on 8x6 direct drive prop. the slow fly props work well too tho. here are some links. http://www.hobbyking.com/hobbyking/store/__26487__Turnigy_DST_1200_Brushless_Bell_Motor_1200kv_USA_Warehouse_.html

For sure dude. I keep fist full of props. Keep in mind the bigger the model the smoother they will fly. Small =fast in most cases. And the specter is the best plane I've ever flown or built. Have fun and if you have rates and expo play with theme to get the model smooth in flight

I have built the ft duster, and am working on the baby blender. Built all but the fuselage of the ft cruiser. Am going to try the bloody wonder and the old fogey pretty soon. Enjoy all the swappable series. However, I am building and using individual power pods on each one. Motors and electronics are not that expensive. So I do not swap power pods. Much easier to use one on each plane.

dharkless December 24, 2013
I have built one Bloody Wonder per the plans and then a second one with some modifications. I took the ailerons off the bottom of the wing and put them on the top. Based on the first build I added 3/8" to the trailing edge of the top first so the aileron joints are behind the trailing edge of the wing bottom. I also let the wings run the full width of the foam sheet so I have a 30" wingspan. I made the fuselage extension 10" long and tapered it down to 3/16" at the back. It stops 1/4" short of the elevator hinge. I also cut the back edges of the fuselage to match the angles on the power pod. I added a canopy at the joint between the front of the wing and the fuselage. It looks like a stealth fighter canopy and is made of just 3 pieces of foam board. The changes make the model a lot more streamlined and more like a fighter jet. If I build another I think I will extend the fuselage sides down to provide side cover for the battery.

I am waiting for gear to arrive to complete the build and good weather. I haven't flown for 15 years and always did nitro. I hope I didn't forget too much...

I tried one more idea out... I made my control horns from a gift card. First cut into 6 equal squares. Then cut each square into two triangles. Then cut the 90 degree corner off leaving the bigger part 7/16 wide. Nip about 1/8" off the two 45 degree corners. Drill 3 holes to match your control wire. Glue them in the same as you would the plywood ones. Makes 12 out of one card. They allow almost 90 degree rotation and they are FREE.

Second, third, or whatever on this being the funnest plane ever! Got loads of foamy store-bought planes, this is way more fun, and hand built by me. Awesome plans and video Flite Test! Keep 'em coming. And the Gift Card Control Horns rule, though I cut grooves in the base that's going into the foam for the hot glue to grip. I wonder if anyone has added some support for the tail section? Extra foam layer back there, maybe in stringer-form? I added a couple barbeque skewers at a diagonal after a hard set down when doing some grass trimming at 3/4 throttle.

When using Windows, when you click to print, the print window opens. About half way down there's Page Size etc. Should be a tab for Poster. Click that, and just below, make sure the scale is 100%, then make sure under that you have "show cut lines" clicked. Print and then trim/tape. Hope that helps.
