My Build of the FT Simple Soarer

Hello Flite Test Community,

 

I have not written an article for a while, (What is wrong with me?) so I decided to document my recent FT Simple Soarer build. I have been wanting a nice toss around glider for a while and since I have really enjoyed flying FT planes in the past I thought I would give their glider try. 

Enough chat, lets build.


The way any FT plane starts. A sheet of Adam's foam board, an IPad, a hotglue gun and some bamboo skewers.

Here are the electronics I used for this particular build:

Two nine gram servos: http://www.hobbyking.com/hobbyking/store/__662__HXT900_9g_1_6kg_12sec_Micro_Servo.html

 

HK 18-20 amp ESC:

Orange RX 6ch reciever:

FC 28-12 Brushless Outrunner

1300mah 3 cell or 1000mah 2 cell, you'repick.

1300 3s:

(Unfortanetly I can not find where I bought the folding prop, but this one would probably work.)

Heres the motor I'm using. It is a bit more powerful than the blue wonder Josh Bixler used on his glider. Since I had one of these lying around I thought "Why Not?"

I did not buy the speed build kit for this glider, but if you are new to the hobby I would highly recommend getting one. They come with everything you need to build the plane for a very resonable price. The laser cut firewall FT sells works very well and is what I used on this glider.

I also bought some of their control horns. You can't go wrong for $4.

Here is the assembled power pod. 

While digging through old supplies I found this carbon fiber folding propeller. With a bit of modifying I was able to fit it onto the shaft of the motor. I want this to be a decent motor glider and using a folding prop really helps with drag issues.

This particular wing was a bit more difficult to cut out then most of FT's wings. I prefer to use a single edge razor when cutting out wings like this, for they have a more narrow blade than an exacto and also cut straight lines more easily. This wing is REALLY long so be sure to have a good straight edge when cutting it out.

Here it is, assembled and ready to fly. The most difficult part was putting in the dihedral. Be sure to use a lot of glue and let it sit for a long time with the dihedral guage in place. Besides that it was reletively simple.

 Another shot of the wing.

 Here are the tail surfaces. For these I used an exacto blade because they are better at cutting curves.

The fuselage all cut out. The biggest thing I have to say for this is TAKE YOUR TIME! If you try to rush the cutting out process your fuselage will not assemble nicely in the next couple of steps.

Here it is, all assembled! Be sure to have a 90° angle close by. 

Here are the installed servos. As you can see it is a very tight fit.

Assembled tail surfaces. Once again a square is very helpful in this step.

Power pod in place. As you can see the folding prop does not really interfere with the design itself.

I had the option of mounting the battery externally, but as I said before I would much rather have an aerodynamiclly clean glider. There is just barely enough room for a 1300 mah 3 cell.

I'll do some testing to see wich battery preforms better. The 1300 runs the motor at a higher rpm, but it is quite a bit heavier than the 1000.

Another shot of the nose.

Here's a shot of me just messing around with the focus on my new DSLR. Also helps show how large this plane is for a swappable.

 Decal Time! No glider is complte without some nice red tail stripes, right.

I also added two bands around one wing to make it easier to spot on high altitude flights.

She's done!

I am very excited to fly this glider but unfortanetly Iowa winters are not the best time to fly...

Ughhh... Snow. Once this stuff melts I'll be sure to post some flight videos and a review of it's charcteristics.

I'd like to thank Flite Test for desigining this awesome glider and you the reader for reading my article.

 

Until next time,

Did you have any problem with it being tail heavy? My dad built one from a speed kit and it came out very tail heavy even with a 1000mah battery. He ended up extending the nose 3" to get it to balance.

According to Josh Bixlers CG mark mine is tail heavy, but with previous planes of his the cg is typically off. After a few glide tests I did it seemed to work just fine. I'll find out in the spring if it flies well or not.

My scrach build was tail heavy. I just had to add one ounce in the nose. Now just right with a 860 mah battery. Thank you for the article . Great looking glider!

As pertaining the the subject of the S.S. being tail-heavy it was my experience with it that, yes it will be if you build it by the plan. However I have found that if you slide the power-pod forward 4 or so inches ( depending on the weight of the motor and ESC you use) it did away with the tail heavy problem. I mount my battery on top of the fuse just in front of the leading edge of the wing (I use 800 mah 3s batteries) and I can fly around gliding on therms and updrafts for at least 30 minutes most of the time and at other times a bit longer. As you slide the pod forward keep checking the CG with battery installed until you get a satisfactory balance. I love mine and will build more as each one wears out.

A P.S. on the above comment. When you extend the pod forward it leaves the fuse un covered for that particular length, so I made a 3 sided cover for it and attached it with a BBQ skewer.
