Bluto -> I need a new RC Helicopter!! (8/9/2003 8:55:25 PM)

My Hawk Sport took a lot of tweaking and a lot of upgrades to make it what I would call an ok beginner helicopter, my Raptors all flew great from the start. My Hawk sport had a bad tail wagg and even blew the tail gears out on the second tank while I was trying to get it all sorted out. This is when you will find out that the Hawk isn't that great of a deal, the replacement parts are not that much cheaper than a Raptor and some are more. I've had problems with the collective being a bit sticky due to not having thrust bearings in the main blade grips, the tail rotor blade grips are very sloppy as they only use one radial bearing per grip. I ended up putting over $100 in upgrades on my Hawk Sport and it still doesn't fly that great, I keep it around for my Brother in-law to fly when he comes to visit, the plan is to sell off the good parts after the first bad crash.
Here's the weak points
Wire Driven tail rotor (It will work ok but can be a pain for a beginner to set up, you can convert it to a torque tube drive for $50) My tail wagg was due to the stock gyro location, I made a platform and mounted it behind the main shaft, now its pretty solid.
No thrust bearings in the main grips (this really isn't a huge problem for a beginner, as long as you run the head speed around 1500 rpm in hover and don't go over 1700 max you'll be ok) I like to run a little higher head speed for 3D flying and the extra force exerted on the bearings causes them to bind a little, the fix is a high torque servo on the collective and even then its still a little sluggish under a load. They have a $40 upgrade to add thrust bearings.
Single radial bearings in the tail rotor blade grips (this could cause some problems for a beginner trying to get the tail setup) again they sell an upgraded version not sure of cost.
There are several other minor things that I don't like about the Hawk Sport but I don't have time to list them all. I'll just say this, if you want a 50 sized helicopter get a Sceadu 50 or Raptor 50, if you want a 30 sized helicopter get a Raptor 30, the Sceadu 30 is a great helicopter its just a little heavy.
