2M Aerojet T33 Maiden Flight.

I have converted my T33 to EDF and it weigths 14kg. Unortunately the manufacturer's center of gravity information in the instructions is not quite correct. It is too nose heavy which leads to the kind of pumping during the landing approach shortly before touchdown. Same behavior as seen in this video. A slightly more tail-heavy set-up leads to much better control on the elevator during the landing approach.

Hmmm … thats annoying isn’t it. I have one with the new stabiliser but it has a K100 in it, I wonder if the lower residual thrust on mine helps with the porpoising which ai get less of.
Can I ask what yours weighs, I would guess 10-11kg?

Hi it’s a friends plane, I think he said it around 35lb’s almost 16 kg.
It sure is sensitive on the elevator for such a small surface.

@@andrewe9155 16kg is a lot, mine is around 10kg dry / 12-13 wet
