A discussion with a fellow RCG member has led me down this path to help solve the issue of how much current a servo draws under regular use and max use current draw. Knowing this information is a great way to determine if an external BEC is necessary and it is also a great way to prevent brownouts and subsequent crashes.

Just think if this information was known years ago. I can only imagine how many crashes would have been prevented if servo manufacturers would list this data.

I have been trying to nail down this data by searching the WWW and was led to a french website that did have some servo draw information. It's fairly old and does not list a number of newer more popular servos.

As a testament on how scarce this data really is, here is a thread; http://www.rcgroups.com/forums/showthread.php?t=2123039 with over 500 views and yet no one has been able to put a finger on any kind of decent data that we can use relative to max servo draw numbers.

ServoCity (my favorite place to buy servos) does help us out some by giving is this for example:

Current Drain (4.8V): 5.3mA/idle and 400mA no load operating

But knowing that is not enough for us. We really need to know what these servos are pulling under load and what is their max draw.

So in an effort to help my fellow modeler, (do I have Mike and Bryan to blame for this? ) I have started down the path to discover something that is not freely known. I hope to get my test equipment up and running within the next week or so and start testing servos. I'll keep a running list of what I learn and I hope this will help us all out in the future. Just like Dr, Kiwi did with brushless motor testing when there wasn't any info out there for us.

And of course I'll list the equipment I am using and post some photos of my test stand so if anyone else wants to try this for themselves they can do it. And as usual, prototypes can always be improved on so yours will be better than mine.

Years ago it was hard to figure out what prop, ESC, Motor, etc you needed to fly your plane safely. Now, there are a number of websites that do the work for you.

Here is how I easily figure out what my next power system is and it only takes me a few minutes to do so.

I have been videoing a few of my balsa builds as of late and as I been doing so, I have have been getting emails, phone calls, and PMs with questions about certain things pertaining to a certain part of a build.

I figured I would extract some of this things from my videos and make them into separate "how to" videos.

Here are some of them and if anyone would like me to make a video on something they do not quite understand or need clarification on, please let me know.

As I make more of these, I will drop them below.

We all know that the Mountain Models Switchback Sport is the quintessential park flyer. Nothing can beat its ability of flying at such a slow speed and yet still be aerobatic enough to keep an experienced pilot happy. It is also a great plane to fly in smaller parks and areas of 1.5 acres or so. I have often taken off and landed my SB width wise on my driveway.

But, along came an even sweeter flying model that has an even lighter wing loading than the SB Sport and two servos per wing. This beauty is call the EVA Sport and is also designed and sold by Mountain Models & Laser Arts.

As with my other build videos, I plan to build this airplane and video the construction of it as a guide to help others in building this plane or as a reference to build other balsa kits.

Below I will list all the components I plan on using in the EVA Sport and will follow that with step by step videos from initial unpacking to her maiden flight.

Please let me know if there is anything I should cover and I will be sure to include that in my video.

For my next build video I plan on building a Stevens Aero SPORTStik.

I am thinking this would be the perfect step up for a beginner wanting to learn how to fly with ailerons and learning how to build something out of balsa. This is a very easy kit to build and perfect for a beginner builder.

I will be using the following components:

Motor: http://www.innov8tivedesigns.com/pro...roducts_id=814

Servos: http://www.innov8tivedesigns.com/pro...roducts_id=138

ESC: http://www.innov8tivedesigns.com/pro...roducts_id=897

Battery: http://www.buddyrc.com/glacier-30c-1300mah-2s1p.html

Tail Wheel: http://www.empirerc.com/dubro-1-1-2-...s-2-p-179.html

Prop: http://www.horizonhobby.com/products...-sf-APC11047SF

We all know that the plastic that comes with the standard SS is pretty poor quality. So I am upgrading the plastic and adding a steerable tail wheel. The parts can be ordered from Millennium R/C.

Stay tuned for the build videos. I'll be posting the links to them as soon as I can get them edited and uploaded.

Here is part 1. And as always, please let me know if I missed something that...Continue Reading

There has been a lot of discussion in the past few years on how difficult working with balsa is and how tough it is to build a balsa kit. Since many of us know that is not the case, even for a newcomer in this hobby, I have decided to make a video while I build a Stevens AeroModel Buzz 400.

The Buzz 400 is the next generation of SQuiRT 400 that many of you have flown in the Wings Across America 2008 adventure.

Here is how to build a balsa airplane.

We all love model aviation no matter what the form. Some like airplanes, some helicopters, some sailplanes or gliders, others like multicopters, cars and/or boats. No matter what form of model aviation you participate in or like to do, at one point in time there was someone to teach you the ropes and show you how to build, fly, or how to know what power system to use on your new model. We were not born with knowing how to fly model aircraft or knowing how to build a foam or balsa plane. That skill or talent was most likely taught to you by someone close to you, or someone you met at your local club. But for some, finding that person to teach them the necessary skills is not always easy to do.

I have found a solution which will make it easier for modelers to get help in their local area, and an easy method that allows providing and offering help to others in this hobby. I have coined the term for those willing to help others “Model Aviation (MA) Mentors.” The idea is quite simple and it uses an online map program that is available to everyone.

MA Mentors can volunteer to do many things. They can teach others how to fly, build airplanes, or helicopters, or multicopters or whatever you choose. Forums are great, but they lack the personal one on one ability and real time interaction that we get working with people face to face. And as you know, looking at a PC screen is no substitute for a real person.

This idea is great for AMA members because as a...Continue Reading
