Hello all.
I have a two fold question here regarding two different models. The first is.
I have the pratt hobbies D Region Tomahawk that is streamer recovered and its about 4 ft lon and 3 inches wide. Its the yellow caution tape.
I want to replace it with a parachute and i have a small field and rocksim gives me a decent rate of 12fps. If i use a Estes 12 in chute and cut the spill hole out, how much faster would the model descend.?
The second thing is the way to work out how far my rocket will drift. My field is about 500ft x 500 approx.
I'm going to use a B6 which rocksim says will take it to 248 ft so that keeping it low for my small field but i don't know how to calculate the drift. I'm bad at math's.
The model weighs about 1.4 oz's.
Thank you
