Flying Legends 1/6 scale Hawker Hunter - ....RC Jet Addiction....
" Here's a clip from today's successful maiden flight of my Flying Legends (Ripmax) Hawker Hunter.
The model weighs 31 lbs dry and carries 4.5L (1.2 gallons) of fuel for an estimated take off weight of 38-39 lbs.
After running for just over 7 minutes I used only half of the onboard fuel so I landed at about 35 lbs. "
