Yep. You say it correctly. The trim tab will remain in the same position relative to the tailplane at all times. If you change the trim, you introduce imbalance, and the tailplane moves to another po
Correct. If you want to do it this way, you need a double pole switch, and use one pole to switch the C-lead to the battery. In our Europa's I think it is not worth the trouble, as the cable from the
I understood the tail plane of the Europa is aerodynamically neutral indeed, and the sole function of the trim tabs is to give the pilot tactile feedback and to push the tailplane in such a position
I agree with this. I'm stating again: The position of the trim tab is NOT an indication of the trim setting. The position of the trim tab is determined by the tail plane... as you can easily see when
Anyone who reached the flying status interested in a harmless experiment? My idea is that if you get the trim tab to line up with the tailplane you will experience less drag. There is a very easy way
Read again what you just said. If the trailing edge of the tailplane moves up, the trim tab moves up even more. It *always* goes back to the same stabile position, regardless of trim setting. The onl
Hi everyone, Who has followed this forum recently knows that the PH-DIY is for some time ready to fly. So far we have not been lucky with our test pilots. We had one very good option in the Netherlan
I have contact with Rob Zeelenberg now, if weather cooperates we are going to do some taxi-testing and maybe more at friday. I got some other offers as well, the Europa-community is wonderfull! Thank
for me. The latter I will do. What happens friday is up to Rob of course. We are not going to push it, but we aren't going to delay it either. We'll just see what happens. Most likely we will not eve
The biggest weight savings can be found by trimming the pilot. 1) Make sure to go to the toilet before commencing flight. 2) Get a haircut. Shave yourself. We're talking about grams, remember? 3) Dre
I agree about the vibration, although if this is a valid argument, why not add even more blades? 7 blades gives even less vibration. ;-) Well, I can't follow this one. Can you explain why? The vibrat
Right. If you increase the amount of power, at some point you have to increase the diameter of the prop. If you can't do this (for clearance reasons), you will have to revert to adding some more blad
It has a lot to do with sound. A 3-blader produces less sound. Furthermore it has less vibrations, and to some folks looks sexier. Performance is another subject. A 2-blade prop IS more efficient. Th
Hi everyone! Today, at 12:25 LT on EHHO, PH-DIY made his first flight. Conditions were vulcanic ash, 17-22 KN head wind (straight on the runway). According to the test pilot, the PH-DIY flies beautif
Thanks! Final test pilot was Robbie Snghal, the empty weight is 421 Kg's, build hours unknown (really!). OK! So, then only the right rudder thing is something to work on. Thanks, Frans
Hehe. There is a story behind that: The painter showed us pictures of his plane, and he had some bright orange circles on his wings, so he was more visible over snow and in the event of a forced land
Did you shim the engine in the engine mount to the "right" when installing the engine... We did, but I'm going to measure again to see if nothing has moved. If looking from behind the airplane, the u
