Hi my friends!!!

Well...finally and after several weeks of no flying because high winds here in central México, here is the conclusion with photos:

1.- The original linkage.- It was made of a weak glow clevis and a very thin link. That wasn´t the correct form, the result; the link is twice and the throtle answer was inconstant. At the middle of stick, I had almost al the power.

2, 3, 4 & 5.- The original linkage was replaced in the engine; by a DUBRO ball link, a more strong rod and, in the throtle servo, with a heavy duty single square link.

In the airfield, I adjust to parameters; the first.- the ATV´s at 85% in rate A, and 85% in rate B. the second.- with the tachometer showing 1500 RPM in ralenti and, 7000 in top power, I adust the exponential curve between the 13 points (photo 6).

The results was succesfully (with a Top Flite 22x10 prop):

1/4 of power at 25% of the throttle stick, 50% at medium, 75% at 3/4 and 7000 RPM´s at full.

To the final adust the throttle curve, I had to fly 3 times. The showings in land, are not the same feelings that in the air, for example; at the middle point, the tachometer shows 3500 RPM (usually 50% of the power), but, in the first flight I feel the middle of the stick so weak. Because this, in land I had to move a few of the parameters.

Again, thanks for all your suport. Without your help, I never can set correctly this.

The plane now is flying great. I had no problem with the mixes; rud to ele, rud to ail and ele to thr.

In my new proyect, I also use the information that you helped me. It´s a GP Edge 540 27% with a DL 50 cc engine. I have started with the mechanical procedure and, the next week I will testing in the airfield and set the radio.

Good bye, and see you soon!!!!.

Sincerely.

Pedro.
