If you do not get an experianced glider pilot to help and you cannot find a reasonable slope with the wind flow up the hill then your first choice will be the toss test flight, there are no other options beside Hi start/winch/power pod.

The park you mentioned is entirely adaquate for a simple hand toss. Grass of course is ideal for this I would reccomend someone besides yourself to launch so that you will be prepared on the sticks. Launching by yourself is not difficult but only for someone with some experiance, Here in lies a difficulty. Most folks even newer RC flyers are overly timid on the launch resulting in a stall at release. Another common problem is launching in a nose high attitude (OK on a winch or hi start to a point of course). This will result in an immediate climb to a stall. Its really a no brainer just a good firm toss absolutely level and not nose up will work just fine Your job will be to just keep the airplane from ballooning up at the launch and to keep the wings level till landing. The landing actually will require no additional effort other than keeping the wings level. you will be shocked at how far this thing glides so do not try to rush a landing it will do better by itself and of course only do this on a calm day and make sure you have every avaliable inch of the field in front of you.

Hi start is the most common option for folks without a ridge site and they work fine but require some room and two people. I would not suggest a hi start untill you have seen it done. Like Flyboy has urged, Get help.

I am currently prpareing a Characture glider bash of a Kadet Senior to be aero towed behind the Kadet Senior in my Avitar and am nearing the first tests of the glider Senior which will be on a hi start.
