Bloody Wonder With Modifications

by dharkless | January 1, 2014 | (9) Posted in Projects

Hi guys & gals,

First I would like to thank the guys at Flite Test for making it easier for people to get started in the hobby.  I did RC in the past but have been away from it for about 15 years.  I was all nitro back then.  When I decided to get back into it I wanted to go electric.  When I started looking around I ran across Flite Test on Youtube and got the impression right away that this would make for an easy transition.

I talked with the science teacher at the local high school about adding an RC module to his classes.  He is very interested if we can afford it.  We are a financially distressed school district but between using my old radio gear and the resources available at Flite Test I think we can manage it.  I am also the Maintenance Director there.  I think the kids would really benefit from a fun yet demanding project like this.

Now for the Bloody Wonder modifications...

 

BLOODY WONDER MODIFICATIONS:

I watched several of the FT build videos and printed several sets of plans.  I decided to build the Bloody wonder first.  I started by building one per the plans.  I noticed that it had some features that were done differently in other models.  I decided to build another one with some modifications.

First i decided that the wings could easily be extended to 30" and use the full width of the Dollar Tree foam board. I also decided to move the Ailerons to the top surface like they were on most other FT models.  I added 3/8" to the top trailing edge since there was a 1/4" gap there on my first build.

Next I decided to make the fuselage extension more stream lined.  I extended it to 1/4" from the elevator gap and tapered it down to 3/16 at the back.

Then I added a canopy inspired by the F117 Stealth Fighter.  It is made with three simple pieces of foam board with back cuts.  

Finally I decided to add contoured sides to the fuselage with curved cowl extensions to soften the appearance.  The doubled bottom edges and cowel should help to protect the power pod on hard landings as well.

I am waiting for the last of the radio gear to arrive to complete the electronics installation.

I am planning to use two aileron servos so I can do flaperons..  

The results are in the photos below:

 

 

 

RAPTOR MODIFICATIONS:

I also did some modifications to the F 22 Raptor from the FT site.  I added removable bottom fuselage panels to cover the gear. The gear will attach to the wing and the covers are attached with velcro.

 

 

GIFT CARDS CONTROL HORNS:

I have submitted a separate article under "Tips' on how to make control horns from gift cards. The picture pretty much tells the story.  Color is magic marker.

 

 

 

Update: 

The modified Bloody Wonder is ready to fly.  32" F 22 in the background...

RAPTOR MODDIFICATIONS:

I also did some modifications to the F 22 Raptor from the RCGroups site.  I added removable bottom fuselage panels to cover the gear. The gear will attach to the wing and the covers are attached with velcro.

 

Update:

This is a 32" F 22 made from RC Groups plans but I made the wing in two layers with a 2 layered spar.  Notice in the second photo the scraps used to set the curve of the wing.  I made a 50% cut close to the spar front and back and used a rounded pen cover tip to depress the joint.  I then used hot glue and scraps of foam board under the edges to preform the two wing halves before joining them.  Top and bottom are the same.  It is really strong but a little heavier.

The fuselage is 3 layers.  Rudders and elevators are single layer. Airframe weight is 408 grams (14 oz).  Gear should be under 300 grams.  Flying weight should be about 700 grams (25 oz).  Wing area is about 3 SF without control surfaces.  Wing loading will be pretty light at 235 grams (8.25 oz) per SF. I will probably add lower body panels to conceal gear on this one too.

I plan to iron the leading edges and will probably add functional ailerons and possibly rudders.

I may build a coutoured fuselage / cockpit using curved panels by removing paper from one side.

I reduced the prop slot for a 10" propeller.

 

 

GIFT CARDS CONTROL HORNS:

I have submitted a separate article under "Tips' on how to make control horns from gift cards. The picture pretty much tells the story.  Color is magic marker.

 

 

CURVED FOAM PANELS:

I am also submitting an article on making curved panels out of foam board:

To make these I removed the paper from the back side and then scored the back side generously with my finger nail. It helps to have a tubular object to form around.  For the lower one I used a large magic marker.

Very nice job. I always thought the bloddy-wonder was a bit stubby and always thought ehh its supposed to have a different "character" look but I like yours alot. I know Ive heard Josh promote taking the next step but what your doing is truly fantastic.

Thanks. I did a lot of designing and scratch building about 15 years ago so it is hard to leave anything alone.

Very smart. Cant wait to see the article on curved panels.

I just submitted it. This one took a few days to get approved. A word of caution, I am still working things out.

Thanks. It is fun to play with these things. If it wasn't so presumptuous i would be tempted to use your comment for a project title.

Thanks for sharing. I like your mods to the Bloody Wonder. Anxious to hear and see the flight info on it.

Thanks. The flight info will probably be a while. I am in western PA and haven't seen much if the ground lately.

Hey buddy. This plane is great.. but the weak point is the satabilizers.. my modified versions were pushers. Flew awsome. But what i did was put the Elevator on the top and cut completely the original elevator. If you dont it will fight against you. And act as a wedge. The elevator on top braces the vertical stabilizers. And looks cool as h€€L. Hope it helps Buddy

I assume you are talking about the Bloody Wonder. The high elevator would make sense if you convert to pusher. Where did you place the motor and propeller, clear at the back or in the middle somewhere? If it was in the back it probably limited the propeller to 8" or so. Where did you mount the servo for he elevator. Did you have any trouble balancing with the motor and servo in the back?

Yes youre correct on my balance issues. FT Bloody Wonder.The way i set it up is with 5 gram sevos (3). One directly on the tail. And 2 for ailerons, pushed against the spar. The motor was a 3800 kv , to get enough thrust on 6x4 prop. Mounted directly ontop of spar. Lipo had to be all the way forward. But these things flew great.

That sounds unique. You should do an article on it.

Thanks. I think i just might build another, and share the mods. Wouldnt mind flying it again, it is a great plane. You keep up posting those mods too !

Great plane and modification done. I'm also looking forward for pusher type Bloody Wonder as what flight monkey did.
