I am waiting for the final engine to arrive before beginning this in earnest. I will be conducting a 30 size 4 stroke engine shoot out. Basically comparing RPM figures with various props and various fuels. The engines to be included are:

Saito FA-30S
Magnum XL30RFS
OS FS-26 Surpass

This request was originally an idea from a YouTube subscriber in Germany who is trying to decide on a power plant for his WWI Air Combat airframe. he is building a Nieuport 28. Following the rules in the attached document. It sounds like a really cool competition.

I already have the 26 Surpass and the Magnum XL30, but the Saito FA-30S just arrived today. I immediately began the break in of this engine in preparation for the shoot out. The OS FS-30 should arrive on Monday.

Since I cannot enter a table here I just made a screen shot of the test matrix. Basically I plan on running each engine using at minimum a 10x4 prop, as dictated by the WWI combat rules, and probably a few others for Min/Max RPM. I will run this test on several different fuels as well focusing on the FAI as that is easily available in Germany.

Omega 10%
Omega 5%
Omega Control Line 10%
Omega FAI 0%

In preparation for the shoot out I tested out a multiple tachometer setup today too. I have been less than impressed with the GloBee tach I have been using lately. The Tower Hobbies one I have is equally crappy. I have since ordered a Hobby King unit and hope it performs a bit better.

That little Saito is one sweet engine for sure!

The 2016 Katie Martin International Tribute was different in so many way. Every year each event takes on a new and interesting life of its' own.

As I have mentioned and as these blog entries are titled, Life is Good again. It has taken me 6 plus years to begin to be a whole person again. If you have followed our career and life, you know Katie and I were one person in two bodies. We were the sum of each other and our strengths and weaknesses were supported by the other. Slowly I have learned to live without her physical presents, although in nearly everything I do, I can feel her presents helping me to find solutions and make decisions that we use to make together.

So, LIFE IS GOOD AGAIN means that I have found the way to continue my life, have fun again, take on challenges and strive to be all I can be on my own. I have had lots of help along the way....believe me. You may have been at one or more of the Katie Tributes...talking with me and letting me talk about slope soaring and Katie....that was part of the help I needed to heal and move forward.....Thank you....You may be one of the thousands of people that read my blog or visit the Katie Tribute thread....this is very therapeutic also and I thank you too.

Each year I get a little sharper and am able to plan and execute my life and the Tribute better. Last year Pete suggested event shirts...he claims his entire wardrobe consists of event shirts...I was not able to put...Continue Reading

Here is another kit prototype rocket glider, using parts from a Cosmic Interceptor rocket kit, inspired by the XB-70 Valkyrie. I used some pre-molded panel lines in the cone to use my rotary cutter to cut slots for the canards, just to keep them straight, since they are lower than center on the nose cone, they angle down slightly but I like the look. Depron wing with turned down tips. Tail surfaces moved forward to clear the elevons. 38" long, 26" wingspan, 11 7/8 oz rtf. In keeping with the nordic theme but avoiding any copyright laws, I'm callign it the Valhalla.

Just a touch of downtrim was needed for vertical boost, glide was very nice with no bad tendencies. Waiting for decals to arrive to finish her up. Also is a video from last weekend in Kent, WA at the raceway with The BEMRC club flying all of my kits plus the bomarc prototype.

So why is it that some 3mm frames can be stiffer than 4mm? And why does it matter if it is stiff or not?

Name: IMG_5211.jpg
Views: 52

A lot of the stiffness factor comes down to the type of weave and layup of the carbon fiber. Using Unidirectional carbon provides great stiffness in the direction the fiber runs, but the perpendicular direction is really weak. This is the reason that most carbon fiber panels are made with 0/90 layup. It gives the carbon really good strength and stiffness in the X and Y direction.

However, using a 0/90 layup isn't the best practice for all frame types. Unless the frame is an actual X shape, most of the fibers will never make a continuous run from end to end. This is where layering the fibers in more than two direction comes in handy.

The layup we use in our frames differs by frame. The Quanic uses a standard 0/90 since each piece can be machined in the direction of the fibers. Pyro on the other hand has a special weave that allows it to retain torsion stiffness since the diagonal motor to motor material is not a straight line. The Invador (H Shaped frame) uses a more dramatically different carbon that gets the strength around the middle of the body to the other side of the frame.

Well the slope fest is coming up fast again,I was lucky enough to get my hands on a couple of 1/4 scale sailplanes that should get air time this year .

Working on a PZ Sport Cub with my favorite power system -- the PZ Sukhoi SU29MM's:
-Eflite BL10 1250kv motor
-Eflite 12x4e prop
-Eflite 40Amp Pro V2 ESC
-Eflite 3S 1350kv 30C LiPo (Sukhoi uses 2200mah stock)

Fun to fly! Feels like a light sport plane rather than a floater.

If i am not too lazy maybe i'll come up with some stickers too.
N010PZ or something like it.

i hear many use an APC 10x7e with the stock system successfully.
...dunno if that includes flaps.

Recently I went down to see Linda and John Stanley of Chestnut Brae, an 80 acre chestnut farm in Nannup, south western Australia. I wanted to demonstrate to them how good quality drone imagery, along with an online service such as Drone Deploy could be used as the base of an effective farm management and planning tool.

Some basic needs of farm planning and management are being able to determine distances, areas and volumes or different aspects of the property. Traditionally this would mainly be done by going out into the field and physically measuring it or perhaps by using low resolution satellite imagery printed onto an A1 laminated poster of the farm.

However its now possible, using low altitude drone imagery coupled with an online user interface, for farmers such as John and Linda to use a tablet or laptop to very easily to zoom in and out of a high resolution map of their property. Zoom levels are far greater than satellite imagery which make using the distance measure, area and volume calculating tools plus much more very accurate, this helps to take the guess work out of farm management ..... all from the comfort of their living room.

It is estimated that 1/3 third of the annual harvest worldwide is lost due to pest and fungal infestation.A farmer utilizing drones can take early actions,and countermeasures to protect the threat of crop loss.Drones equipped with multispectral cameras determine areas of pest infestation before irreversible damage of plants occur.The information provided by the drones will determine which areas need to be sprayed,thus reducing the volume of pesticides used.Applying these technologies will improve the quality of foods,and reduce the overall pesticide costs to the farmer.

I got this RTR buggy from Banggood and made a video to unbox it and give it a test drive. Pretty cool RC, it was fun to drive. Would make a pretty good beginner RC.

I got it here on Banggood's website if you want more info on specs and pricing.
