How to Remove the Color and Glue from Balsa
0Sooner or later it happens to all of us, we crash a plane. After the initial shock and disappointment it’s a process of getting all the pieces and going home to survey the damage. I usually let mine sit for a day once it’s in the shop….maybe I’m hoping it will cure itself, but most of the time it just seems to help to step back and let the crashed victim rest.
Once the damage has been evaluated and the decision made to repair it, the work towards recovery begins.
Once the woodworking is done there is the preparation for covering. Removing the old covering is usually pretty easy if you apply a little heat before you start pealing, but there is always a little bit of residue color/glue left. If you leave these spots there will be ridges under the new covering and you will hate the way it looks.
I use a technique of applying some clear packing tape over the remaining color/glue and then peal that up. It usually removes the majority of what’s left. I generally use a little heat before I apply the tape. It might take a couple of times to get it all, but any remaining residue is easily cleaned up with a rag and some denatured alcohol. Some folks use acetone and that works well, but I prefer alcohol because it’s less toxic.
Hopefully the video will clear up any questions.
Weatronic 2.4 GHz Conversion for the Multiplex Royal Evo
0In my continuous challenge to try new conversions for 2.4 GHz systems, my latest is the Weatronic dual freq frequency hopping spread spectrum system. I’ve been aware of Weatronic for a few years and their high end receivers that incorporate such things as voltage regulators, gyros, and GPS. Until recently when they introduced their new line of “micro” receivers it just didn’t seem like it was worth my money to try. I say that not because I’m cheap, but their systems are extremely high end and worthy of such things as $20K jets and other incredibly complicated aircraft. I don’t fly anything of that nature.
The recently introduced their “micro” system and the Weatronic system suddenly became a system that was suitable for “the rest of us”…meaning the normal guy at the local flying field. Prices are comparable to the Spektrum 12 channel conversion for the Royal Evo radio with 12 ch receiver.
The conversion couldn’t be any simpler. The video shows it in real time including my mistake of swamping the signal by having the receiver too close to the transmitter module. This resulted in an error signal from the module, but the significant part is that the signal itself remained reliable enough that had I been flying a plane it would have been fine. The micro SD card in the Tx module records the signal strength during the flight and it showed plenty of reliable channels still remaining to ensure solid control. This system is the most rebust of any system I’ve tested to date.
The GigaControl software really is remarkable in its capabilities. With the 12 ch Evo I’ve been used to assigning a channel and servo to every control surface. That means on my big biplanes I use four channels for the ailerons, two for the elevator and one for the rudder and throttle. That’s 8 channels and easy adjustability. With the Weatronic system and software, the same could be accomplished using a four channel radio talking to the 12 ch receiver…or 8 channel receiver if you wanted to save some money. The software allows you to assign multiple servos to one channel and still be able to trim each one with the software separately.
The binding process is like most spread spectrum radios so there’s nothing odd about that process. The module atop the transmitter might take some getting used to if you’re used to seeing an antenna, but I can assure you within a few minutes, you won’t give it another thought. The module gives real time feedback thru lights and optional speaker if you exceed the set parameters for temp, voltage or signal strength.
I’ve only begun to test the capabilities of this system, but so far I have to say I’m impressed. There will be a more complete write up of the radio in my Model Aviation Magazine column in the October 2010 issue. There will also be a complete write up of the 12 ch micro receiver in a future issue of Model Airplane News, but I don’t know the issue date yet.
Yes – I’m Still Alive & Well
0It’s been a busy few months and I’ve gotten way behind on updating the blog and the website has been dormant for ages.
I’ve got three electric ducted fan projects to get posted that have been done for Model Airplane News. Each is from Hobby Lobby and I have to say they seem to get better all the time.
I’ve also done some traveling and got to visit my newest grandson in Denver, CO. That’s always a great trip in the motorhome, but it’s a long way from NC to CO. We had everything from snow to 75 mph gusts while there.
A real biggie for me was visiting Estes Park, CO where The Stanley Hotel is. That’s the hotel where “The Shining” was filmed and I swear I could hear Jack Nicholson saying “here’s Johnny” while I walked the haunted halls
I’m still on the road as I write this and will get busy updating things when I get home. Stay tuned, I promise I’ll do better…..no honest, I mean it…..you believe that don’t you?
FMA FunJet (aka SkyFun) Hands off Landing
0I finished the FunJet from FMA Direct before Christmas and we did several test flights and video, but I’m just now getting around to posting it. The airplane can be set up to be very sporty and the roll rate will surprise you. It’s a blast to fly and I can turn the CoPilot II system on or off from the transmitter. The kit is very complete and comes with everything installed except your receiver.
And here’s what I promised, the hands off landing. Wayne held onto the transmitter and was ready to recover it because he didn’t trust it yet. By the time we did it for the fourth time I set the transmitter on the ground and it did it perfectly again. Really an amazing thing to watch. We haven’t been able to fool the copilot system yet and we’ve really put it in some extreme attitudes. I am VERY impressed with this system.
Update/Correction for Evo 12 Module from Spektrum
9It turns out that the Spektrum 2.4 module to convert the Multiplex Royal Evo 12 Radio needs a little modification before the radio will actually work. You must put a jumper on the main connector (white in the photo) between terminal #2 and #5
Once this jumper is installed, everything works perfectly. I talked to Horizon today and they didn’t know about it or that there was a problem. Now it’s solved.
[Update 1/27/10] This is only a problem if you have the Royal Evo Pro version of the radio and you will still need to ensure the software version is 2.62 or below. Multiplex has taken steps to block the PPM signal to disable 3rd party modules requiring direct PPM input.
The Official Spektrum Module for the 12 channel Multiplex Evo
0At long last, Spektrum has released their full 12 channel module for the Multiplex Royal Evo radio. Unlike the hacks others and myself have done using the Spektrum Futaba module, this is designed for the Royal Evo or the 3030 radio. No more misaligned channel numbers or reducing our 12 channel radios to 8 usable channels.
The one caution I would advise is to be sure you have software version 2.62 or earlier if your radio is a Royal Evo Pro version. When I sent mine in for repair it came back “updated” to the “Pro” version and luckily it had the 2.62 software. If yours is a later version you can downgrade it by getting the older software and renaming it so the installer will use it. The newer versions have made it so PPM signals aren’t present for the modules to work. Nice work Multiplex
Here’s a video of my conversion today. It takes about five minutes if you’re not doing video or taking photos of it for articles.
FMA Direct’s FunJet with Co-Pilot II
0I’ve just finished up a project that will be in my April 2010 column in Model Aviation Magazine. This one features one of the new offerings from FMA Direct’s Model Shop. They offer a Cessna 182 or this FunJet that I bought.
The real feature of this plane is the new Co-Pilot II system that comes already installed. When I do a post about flying the plane, I’ll go into that more.
Here’s a look at what comes in the box.
3D Joe Nall Jet
0There were two of these from Europe at Joe Nall this year and it was something to see. I’ve got more clips, but need to find them and edit them into a video. Here’s a teaser though and listen to that turbine engine!
Hobby Lobby Su-34 "Fullback"
1I recently did a review of the new Su-34 from Hobby Lobby that features 180 degree thrust vectoring. Since I did this, there has been an upgrade kit released to allow 360 degree vectoring so you can have rudder thrust for extreme flat spins.
This is an all foam ARF that arrives with everything installed except your receiver. The twin motors, ESC’s, ten servos and retracts are already installed when it comes out of the box. The kit even includes the 4S LIPO pack although it’s just barely capable of handling the 60 amp current of the twin motors. You’ll do well to upgrade this battery.
The flight characteristics of this plane are remarkable when you turn the vectoring on. This is selectable from your transmitter and you can choose to use only elevator thrust, aileron thrust, or both. It had no trouble flying from our grass field as you can see in the second video.
This airplane will be featured in the March 2010 issue of Model Airplane News and is on the cover.
Here is a little video of the test flight.
West Mountain Radio's CBA II
0I’m a big fan of devices that make caring for our expensive battery packs easier. West Mtn Radios had a device called the Computer Battery Analyzer II that makes this a simple process without breaking the bank. Since I did this video they’ve updated their software and also come out with a CBA III that I haven’t tested yet. The ease of using the CBA II makes it one of the more intuitive devices I’ve tried.
Within a few minutes of unpacking the device and installing the software you can be ready to test or discharge your cells and packs to storage levels or simply determine the health of your packs.
This video is a bit long, but it gives a general overview of the device features and software.
