Tab Number 69

I started building the brackets, that once welded to the frame, will be used to bolt the two aluminum rails that form the floor inside the plane. I reduced some 0.100 steel scraps to 0.050 with a bench grinder, than i gave them a rough shape and than i filed up to give the final shape. First one done...seven to go!

Throttle Lever

I spent a couple of days building the throttle lever. Not hard task, but took time! anyhow paid back time!
Just recently i heard that Aviat asked 200 dollars for the throttle lever without PTT button installed!
Here it is my, 5 bucks, throttle! Actually i have these duroplast knob "as per plans" but soon i'll go for a tubolar throttle handle with a PTT button.

Having Fun!

One advantage that you have when you build an experimental aircraft is to be able to customize. Now, I'm not that kind of engineer who makes significant changes, but small changes that make it more enjoyable and add performance or make you save money, are welcome.
So here I am, this is my trim lever! Instead of aluminum is made from a 4130 steel scrap!
Has the same dimension that plans call for, but to reduce weight i made those holes inside, which reduced weight from 135 to 90 gr.
Then i added a little lug to give extra lateral resistance.
So, it's a little bit heavier, but it's free.. tougher...and much pretty!


 Rough dimension.
 Cutting holes, not easy task... these saw is to small!!
Done! Now i need to decide whether to mount the small ball or the big  one! (plans call the small one).
