I will now complete the electrical connection. Then it will follow the first flight. Details will be delivered last.

Because the model has new controllers, I had to draw a new circuit diagram.

I finally finished wiring the model and the model is ready for a test flight. I am waiting for tall grass, my favorite meadow. I attach a short video motor test.

The maximum speeds do not regulate and I will therefore drive the climb to the size of the propellers. Now the propeller is 3/2. The total weight of the model is 160gr. For comparison, HP W8 with two engines weighed after all final adjustments 120gr.

S4zb, I love this airplane project of yours. I'm particularly impressed with the engine control. Are these controllers commercially available? I like the idea of two power phases, climb and cruise, which makes it helpful when adjusting the flight pattern. I also like the way it delays at the beginning.

I look forward to seeing it fly. Well done!

Hi Ivan,
it looks great, sounds great too! Looking forward to some flight videos... What is the total weight


Rich,
timers with these functions have been available for many years, at least in Europe. They are standard for indoor scale models. I must admit, I did not know this supplier Ivan uses.

But since my Czech is not very good ( Grin) here are the other known ones:

Atomic Workshop Zombie (for brushed motors)
http://www.atomicworkshop.co.uk/catalog/index.php?main_page=index&cPath=66&zenid=69mn3397kcga1afdnvdirc7ju2

K&P timer (scroll down)
http://www.kpaero.com/productreport.aspx

In Nijmegen last year there was another one available, by Jiri Dolezel, but I have no website for that.

The timer I use is simple, inexpensive and is only suitable for models that fly outdoors.

I'm slowly starting to fly. The video is not good, next time it will be better.

That looks  very good.  A little more trimming perhaps and it will be there I think. I do not know if there was some wind but if so it seemed to handle it very well.  You have done well. I am pleased for you.

That last flight was stately!   Just some tweaking needed.

You have some lovely tall and soft grass.  I'm envious.  Great flight that last, and an excellent model.

  Well Done, almost there, I know you are quite capable of the final trimming but could I suggest a bit more downthrust in the outboard engine to dampen the stall and in turn it will hold up the inside wing. Please take this as a suggestion only.
   I am very envious of your flying field also,
