Hi Seedo,
The thrust to weight ratio to make an aircraft go vertical is 1 to 1 or better.
Modern jet fighters have better than 1 to 1 when they have used up some of their fuel and are not loaded with maximum armament.
To make an aircraft fly a thrust to weight ratio of far less is required a 747 has a thrust to weight ratio of 0.25 to 1 for example.
The Wright flyer had significantly less.

Your thrust to weight ratio will be capable of vertical acceleration!
You could easily fly on one engine with 700g of thrust even climb quite steeply.
Hope your reflexes are good a couple of seconds of full thrust will be out of sight!
Be sure to have plenty of space for your first flights.
