    Fred, Puppy # 1 (mechanical, big and red) is just behind and near an accu. In my case it means it is over the banana tray. When flying, it is not very erconomical to use it by P1 but it is reachable by stretching the safety belts a little. On the other hand I will never use it when flying, emergency or not. That is it. I elected this place to minimize cabel weight and labour also. One extra benefit: this mechanical key is removable. That is a safety effect also. When the key is removed, it is much more hard to steal my Europa (in fact that thief would be quite skilled and/or mad if he (I point *he*) desided to fly my Mono out. Would be an interesting experience to see it!). The key is secured by detachable lanyard (that is against a mad passenger "hey what is this?" and "where it is now?"). Puppy #2 (electric rocking switch with 40A automotive lightweight light relay) locates as per Europa = panel=B4s left-down corner. I forgot to mention: of course it leaves also trimming system operative when switched off. When switched off, I have to switch also trim circuit breaker open to switch off trim power when parked. During emergency, it is still operative because CB is on. BTW I have no C of G problems at all; I have a fore located accu and The Airmaster CS prop and "some" other fore located gizmos. With an empty tank and a passenger 140 kg /62 lbs (!) C of G is still at fore limit. I am sure you understand Finnish enough to follow attached xls table.

    First: Any plane can only be trimmed for one speed. Any change of speed will require adjustment of trim. Second: We have anti-TRIM-tabs. Mind the trim part of the description. Without deflection, the plane has to be at the designed zero trim speed. Any other speed will require trim, in other words: deflection. Third: If the anti-trim-tabs could or would be level, zero, at any speed, you would not need them. It would be quite stupid to invent and add them in the first place. Frans, in your unique case you could save a lot of complicated, potentially dangerous, heavy metal and remove all that stuff. Just fix your trim tabs to neutral for ever. All readers: This is not a seriously intended, potentially dangerous advice. Please discard the idea, i shall not be held responsible!
