Hello everybody,
Am going to trow something in to your direction see if you guys can help us figure out the possible reasons of our crashes. I own(ed) a brillelli 26 which i had in my CMP giles 202. I have flow my new plane about 9 to 10 times, flawlessly. My friend, own(ed) a dl-50 which he had in his stinger. This plane also flew about 8 times flawlessly. However last Sunday we both lost both our planes and our engines due to fatal crashes.
The strange thing is that we both lost them within half hour from eachother and in simmilar manner. Note, we were the only two gas engines on the field. Both planes did the same "maneuvers" and kissed the ground. I was going downwind in a level flight, I had the plane quite high. All the sudden I felt like I lost radio contact and the plane spiraled straight down. After about half a second I regained controll over the plane and put it in a left bank heading towards the strip for a landing. However about one secon later, it did the same thing but all the way towards the ground. I had no controll over it whatsoever. Well, about half hour later, it happened EXACTLY the same, with my friend. The same sequence and the same spiral dive.
We still cannot figure out what might have caused this. We had each at least 1ft seperation betwee radio and engine (by the book). Needles to say we are a bit hesitant and (scared) to reinvest in the same type of combination, here gas engine seeming to be the common issue since my radio system is futaba and his is JR. The only thing a bit out of the normal was the weather. Uncommon for Aruba, we had overcast and here and there a bit of rain, or mist, cannot really call it rain.
Needless to say we want some input as to what we might have overlooked or what might have happened.

Guys Please shed some light upon our darkness

Thanks

P.S. My engine used the fly-wheel and my friend's had an electronic ignition.
