Hello!

I had quite some pause in my RC activity. My daughter had priority over RC stuff, so please excuse my lack of posts.

Now the indoor season is going, so we can join in a school sports hall on Friday evenings for one and a half hours.

Outdoors flying is probably getting very problematic in the future, our club is being kicked out from our flying field by the municipality. Unfortunately there is quite some politics and corruption involved, so we don’t really have much of a chance in this game.

My 10th flight was rather boring probably. I haven’t been flying for quite some time, so I tried to freshen up my reflexes.

My latest indoor flight was the 11th flight with my Extra300. I used a new camera for recording, purchased recently an SJCAM SJ4000 action camera. It is basically a copy of GoPro3, with some attractive pricing.

The camera is rather okay for my application. I knew that it has some limitations, so I was not expecting it to beat the latest GoPro4 series. For instance it has some issues with white balance and it would not work so fine for FPV either. It cannot do 60 fps, only 30 fps. But it is fully compatible with GoPro accessories and has a rather okay picture for the price. I made some very simple reviews of it, you can find some videos below.

I look forward to fly a bit more during the winter season.

Hello,

It was quite some time since I reflected on my Extra300 EPP indoor plane. The build was rather long and I had many questionmarks. I think this happened partly due to my inexperience in building and due to the manual being written by a very experienced senior pilot who mentioned only the most important aspects of the build. I am not even novice in building, so I would have needed a lot more detail in building instructions.

Anyhow, the plane is ready and it flies well. I tried to take a stepwise approach with flying. I knew that indoor flying would demand constant usage of rudder. While flying my Easystar I started to turn with rudder and aileron together. So I made some rudder practice to prepare myself for indoor challenges. However I knew that playing with rudder while having “the whole sky” to my disposal is rather easy. I was prepared for some crashes as I knew that indoor will be a lot more difficult.

To not ruin the plane within 10 seconds of flight I tried to practice on the ground first. That said applying a fraction of throttle and “driving around” in circles rather than lifting off. This was more difficult than I have thought it would be, since nothing was trimmed and I had a new radio system even. As result I had some occasional unintended takeoffs. These were aborted mostly, that said I crashed the plane nose-in to the floor. Like a warbird tip. I consumed propellers at some rate 🙂

Maiden flight:

2nd flight:

3rd flight, I started to enjoy high angle-of-attack slow passes. Not easy, but fun. Tried to mix directions, figure 8 and slalom flight. Very exciting to do, maybe not so exciting to watch, though.

4th flight, I tried to transition to hover.

5th flight, with hovering practice.

6th flight, more hovering and fun flight.

7th flight. I started to grow devil horns, had some “moments” of daredevil actions. Landed on the wall for instance.

8th flight, my first roll indoors. Scary but fun.

I skipped last weeks flights as I was fortunate enough to have my daughter born. She was born at 1:30 on the 20th of January 2014. A real miracle, 49 cm and 3230 grams of new life. Funny enough it is my birthday, I received the best possible present ever! I stayed home to help my wife and the baby, no flying right now. I will regain action soon, just need to sort out the first few weeks with helping around.

I am not sure what will happen to our outdoors flying. The flight club is going through a very difficult time period. The council announced that they will remove us from our flying field. As from 1st of February 2014 we are no longer allowed to use the field, we have to clear the area and cannot return. We haven’t received yet any other area to use, so the very existence of the club is in danger.
Our flight club and cross motorcycle (dirt bike if you like) club is removed from the area. The cause for this unfortunate decision is that an investment group tied to some politician tries to build a set of luxury golf flats in the area. It is rather interesting, since the golf club itself went bankrupt several times during the last few years. Besides that there are many issues around the build plans, as it seems politics and corruption got mixed up things quite a bit.

The club tried to apply for a negotiation, but the council does not really listen. So as for new it looks like that 1st of February is the end of our current flight activity.

I don’t know yet how we will do. There are some locations where I can fly, but the club itself will not be able to survive without a flying field. We will see.

Hello,

Spring is here, the long winter sleep is over. I haven’t been flying for real for the entire winter, only did some simulator practice. So when time was ready to actually fly I was rather nervous.

To cure the lack of fingertip feel I launched the simulator to get some reflexes. Please find some hovering exercise with an Ultimate biplane.

I observed great interest in this plane, ArcticRC and his mate fly this model in the North of Norway. Great plane, great recording.

Nevertheless, I am still flying my modified Multiplex Easystar. I plan to learn flying more before I build a new model. Need to get more confidence in hand starting (although that it might not be needed with planned models), also handling wind gusts and of course flying more stable. I think the more practice I gather with current plane the more I can avoid some stupid mistake with future planes. Although that pilot error is never excluded, how much I might practice.

We had some promising weather during the week, so on Thuesday after working hours we drove to the field and started flying. Clouds around us were rather threatening, wind gusts came from nowhere, but overall conditions were okay.

I had some problem with one of my mini cameras, so I just have the hat cam and the Hobbyking Wing Camera recording. Anyhow it is more than enough material.

I managed to start and land without incidents, however once I did a full roll without willing to do it. I was subject to a stronger wind gust, the plane was tilted almost 90 degrees along longitudinal axis. I wanted to correct, but did not react fast enough and this let the plane do a full roll without me doing really much about it. I think I started to correct but was more amazed by the fact that my Easystar can fly “so advanced” than I was ready to act. Fortunately I was at altitude, so the plane did not lose height that it became dangerous. After this happening I was more alert and could correct wind gusts.

I did some low passes, also some gliding.

My conclusion is that this 3-blade propeller is not really god. It makes transportation much more difficult. The wings cannot be stucked close to the fuselage as you have a blade every 120 degree. With a conventional 2-blade this is no issue. The efficiency is lower, this results is loss of power. And for some reason even though that I have reasonable pitch on it the motor revs crazy high. So I did not dare to use it on full throttle for long.

I ordered APC 6x4E pusher props, will mount one when I get them. That configuration worked much better, but I cracked that prop earlier. Hence the try with 3-blade.

Here is my 11th flight, please check it out.

Hello!

I am not flying for 2 weeks now, the weather is really bad here. We got some storm called Katia, lot of wind and rain. So no flying outdoors.

I had to do some simulator flying, no other option is working in these days.

Since I never really used rudder for more than correcting some turns I though that I need to get more advanced in this question. Doing a knifeedge seemed a good point. What does knifeedge mean?

Knife-edge means that the plane flies 90 degrees roll and altitude is held by the rudder.

I started to do practice runs in simulator. Crashed maybe 20 times before it started to work for me. You need to compensate for the speed and rudder in order to have proper speed and altitude. And of course holding the plane in 90 degrees roll is important as well.

Please take a look at how I managed:

For a first attempt it is okay. But I need to practice a lot more before I get a rock solid knife-edge in a perfectly straight line. Long way to go 🙂

Best regards,

Sir Crash a Lot

Hello!

Happy Easter!

I thought of practicing with simulator again, need to prepare for Easystar maiden flight. For this I committed an A.A.S. what stands for Another Act of Soldering 🙂

I had two flat type Li-Po batteries for transmitter usage, one is used in my helicopter radio, the other is a spare. Since the Lama v3 radio transmitter that I use for simulator control is without batteries right now (I used them up for the Turnigy 9X v2) I had to mod that radio. Now it features Li-Po as well.

Back to the practice, I tried to fly smoothly and after a while I tried to coordinate my turns with rudder while compensating with ailerons. I don’t say that I managed well but tried.

I also comment on my pilot errors, you can read my comments during flight.

I think I will practice more until next week, when I may do the maiden some day. This is getting exciting!

Best regards,
