BARRACUDA EDF VIDEO

VideoParkJets

For those of you that haven't had a chance to get on over to and check out the newest RC plan on Parkjets, here is the video of the EADS Barracuda.  The plan file contains plans for a 68mm (or larger) EDF fan and also a mini version of the EADS Barracuda that is roughly 60% size and fits a 50mm EDF fan. 

PROP TO EDF CONVERSIONS

KnowledgeParkJets
Probably the number one question we get in our inbox is whether we have documentation to convert some of our excellent RC "pusher" prop plans into EDF, or electric ducted fans power.  Since we get the question all the time, we thought we would spend a little time discussing our feelings on the whole subject. If you are roaming around your local hobby shop, you will notice a lot of the boxed RC airplanes come set up for EDF.  So it has a lot of RC builders wondering if its a right fit for them.  Let's break this down a little. 

MIG 29 VIDEO

VideoParkJets

This is a great video of a scratch build MIG 29.  The video starts at the beginning, from the traceing process, the cutting, the assembly of the components, the installation of the electronic equipment, painting and finally the first flight.  A great example of a hobbyist taking a piece of foam and transforming it into an RC airplane that looks awesome in the air. 

BARRACUDA UP CLOSE

InterviewParkJets

We recently got a plan submitted to parkjets.com via E-mail that caught our attention, the EADS Barracuda. Being that it was all the way from Germany, of a German design, it was immediately pretty unique. Here is the meat of it:

Hi...a few weeks ago I got bored of flying RTF-models, so I decided to design and build my own aircraft. Parkjets.com helped me a lot in that process so thanks for that. I based my design on the EADS-Barracuda, a prototype drone aircraft. It ended up working better, than i thought it would, and the final model is an easy to build, unique looking EDF....Sabastian.

We decided to talk to the designer a little bit more about his design and got some excellent feedback. We think it will provide you with some insight and ideas about designing and flying. So here we go.

BUY OR BUILD

KnowledgeParkJets

Sometimes we here at Parkjets get the very good question related to whether or not its best to buy a ready to fly airplane or whether it best to strike out on your own and build it.  Most of the time, people want to know which is cheaper and what is the real difference (besides the obvious).

NEW CAD SOFTWARE

KnowledgeParkJets

We recently had a site visitor suggust we post a link to a new FREE CAD software location out there on the internet.

GOOGLE SKETCH UP & PARKJETS

KnowledgeParkJets

We recently got an E-mail from a Parkjets.com visitor that was interested in putting some more plans on Parkjets.  We love this kind of E-mail.  However, the individual had no idea how to put his plans into electronic form.  

There are many different programs out there to help people with Computer Aided Drawing (CAD) but one program has pretty much cornered the market for part time designers.  Google SKetch Up.

SOLDERING IN RC

KnowledgeParkJets

One of the essential skills to have when starting out in R/C is the ability to solder a few connections together.  It may come to the surprise of the new moderler that often times, connectors on the ends of batteries and motors require you to break out a little soldering iron and a few minutes of time.

First up is a great 15 minute how to on replacing bullet connectors on your electric motor. 

INSTALL SERVOS, CONTROL HORNS

KnowledgeParkJets

Many times, we get E-mails on how to install servos, push rods, control horns and all the various components needed to get a simple foam parkjet off the ground and actually be able to control it.  

As it turns out, we found an excellent video made by the guys at RCSUPERPOWERS that clearly explains the whole process, so why reinvent the lesson?

HOW TO BEVEL CONTROL SURFACES

KnowledgeParkJets

In an effort to expand the knowledge here on Parkjets, we thought this video is a great instruction on how to bevel the edges of the control surfaces and hinge them on your foam parkjet.

The video is produced by the guys over at RCSuperPowers (who have great plans on their site) and is a great example on how easy it is to work with foam.  

FLAT PLATE WINGS

KnowledgeParkJets

For the people that are new to RC and parkjets in general, the question always comes up - Does a flat plate wing work okay or should I spend the time and money to have a real airfoiled wing made?  Great question.  

One the things that makes parkjets so popular is the ease of construction. Throwing on a flat piece of foam and rounding over the leading edges is certainly a lot easier than getting an airfoiled wing made.  

NOTE ABOUT FREE PLANS

KnowledgeParkJets

These plans are NOT owned by Parkjets.com, they are posted on the Internet and they are owned by the persons who created them.

We assume no responsibility for what you do with the plans, most creators want you to build them for your OWN PERSONAL USE.  DO NOT RESELL THE PLANS.

FREE CAD PROGRAM

KnowledgeParkJets

So what if you want to ditch the pencil and paper and move to a more precise form of drawing up your plans but don't want to spend a bunch of money just to draw them up?  Simple, download this free CAD program and get to drawing.  Sure, its a little limited, but should work well for most people.

PLAN PRINTING SERVICES

KnowledgeParkJets

So you are ready to print your plans but don't have a Kinkos or other printing service around to get the job done.  Now what?  Well, there are a couple of options for you here.  

Winger Models is a great choice For Original and Reduced Size Plans.  Almost all plans offered on Parkjets are included.  You can pay via PayPal.  Buy On-line and have the plans mailed to you.  It's that easy!

BUNGEE LAUNCHER PLANS

Building, KnowledgeParkJets

Sometimes it's easier to get your parkjet in the air if you can use a bungee launcher.  Sometimes the plane is too big, sometimes its just hard to hold.  There are plenty of stories out there about pilots getting their hand or arm cut in by the propeller and that usually requires a trip to the emergency room. 

Here is a great design for a home built bungee launcher that incorporates a foot pedel so the entire thing can be operated by one person.
