i've always been told that on take off that i should have a flat trajectory, jump for the back of the pit. my question is would it be better for me to jump up or out when leaving the ground on the plant. i'm 5'11'' 160lbs on a 14' 170 pacer with a 17.3 flex and the highest leagal hand grip. i'm getting into the pit just fine jumping for the back of the pit, but haveing trouble inverting

This might be my problem as well. I am bending my pole way too much and I am getting 0 pop from it. Its recoiling too slow and its really hurting me.

flat trajectory ....aka...sitting on the pole....aka.....looking for trouble

I will try to interpret for Altius

In order to land where you are supposed to, you must get the pole to vertical. By jumping up (your speed will automatically carry you forward) and taking off just before or as the pole hits the back of the box you can maximize the angle of the pole to the ground at take off. This means you have to move the pole that much less to get it to vertical and you will get deeper into the pit if done correctly. Also the greater the angle, the lower proportion of energy that will go into bending the pole (and therefore the lower proportion that is wasted by the imperfect nature of pole recoil) and the higher proportion of energy that will go directly into raising your center of gravity.

(anyone feel free to correct anything i said incorrectly)

The reason that you aren't getting the response you want is becaue we just had this conversation 2 months ago.....make sure you look at past threads before you ask a question.

A lot of people get tired of answering th same question over and over

Well truth be told the perfect takeoff is 0 degrees the problem is you need to be running at roughly 30 m/s. I speed I doubt anyone will acheive so I guess your right.

In theory I would have to agree with you......a jump would be unnecessary if the pole could be penetrated with only speed.

We could have a new event. At a 0 degree take off angle and 30m/sec take off speed -rocket assisted of course - folk could compete to see how far back down the run way they could be projected. Would be fun to watch! :idea: :yes:

However a 0 degree take off angle and 8.5m/s is just about enough to get you killed on the right - or should it be wrong - pole. :crying:

Ive heard something about an 18 degree angle at takeoff being the most effecient??

Does any body have a giant protractor to measure this?? jk.
