RE: HOVERING RATIO???
Buy a 15lb digital fish scale, weigh your aircraft, then put a string around the tail on the ground and run at full power, and see how much thrust it has. that will give you EXACT readings. For example, my Showtime 90 weights exactly 9lbs now (dry), and with Saito 100 on 30% nitro and APC 16X4 prop the plane pulls a constant 12.5lbs of thrust, so I am 1.38 : 1 .....it can hover but you better be up high as there is not much extra power to pull out of any problems.
You can buy a scale at any sports store, get one for around 15 to 20 lbs MAX, as they are more accurate on lighter loads.
