I found the instructions straight forward but there were a couple of typos where the pictures were in sequence but not numbered correctly. I would suggest adding more double sided tape when attaching the wing cover on the bottom of the wing. Mine didn’t quite stick and I ended up tack glueing it to make it stay put. When installing the motor it wasn’t quite clear that you will need to pull the cowl off first and complete the installation. Also, if you use the larger ESC, you will need to enlarge the opening in the firewall.
Flying the plane is where the fun began and a bit more research. The first flight resulted in a take off role of less than five feet on short grass. The Sea Fury required zero adjustments on the trims. I flew with the high rates and it does nice loops and rolls. It looks super cool with the gear tucking up on a plane of this size and coming down for landing. That last part is a challenge. It requires a proper use of the elevator on the flare not to get the plane to nose over as I found out on my fifth flight. The Sea Fury can also be hand launched and belly landed. If you are going to hand launch it, leave the rockets off as they will pull out on landing.
Although the plane flew great, I thought it could use a bit more speed and tried a couple of tests. First, I substituted the recommended E-flight battery with a Thunder Power 3S 11.1 V 2200mAh 25 C eXtreme V2 Li-Po and noticed a bump in power and longer flight times. Then I swapped out the 10 by 8 prop that came with the plane with an APC 10 by 10 and saw another significant jump in power. The 40 amp ESC can easily handle this. The plane will fly in an area about the size of a soccer field and since it’s so small makes it a great plane to take along in the car and fly at lunch.
