Default Choosing a 450 sized heli from hobbyking

I've decided I would like to properly fly rc helicopters. I've flown a few coaxials that require no skill, as well as learning on proper simulators (realflight). For my first helicopter I think 450 sized is the size for me - although 500 is more stable, I think the added power needed and weight of it make it a bit much.

I already own a Futaba 6EX system I can use, so I don't need to buy a radio. I also have lipo chargers and balancers. I'm a fan of hobbyking, and think I will probably get the actual helicopter and accessories from there. So, I need to decide on:

A helicopter

I have no idea which of these to get - I've heard the torque tubes are less forgiving, so I'd be tempted towards the HK-450GT Pro. However, this doesn't seem to be full alloy - so why is it more expensive? Any thoughts?

A motor

The 2215 seems to be popular, although the 2218 seems to have a little more power. Are there any disadvantages to the 2218?

Any suggestions for parts or ideas are much appriciated. I've read most of the 'HK-450GT CCPM Alloy T-Rex compatible' thread on this forum, but the range of equipment people are using leaves me a bit confused when it come to choosing mine.

Thanks

Andrew

I'm not sure if this should be in the T-Rex heli section - if it should be, could a mod move it? Thanks!

Default RE: Choosing a 450 sized heli from hobbyking

You have probably ordered one by now. I have the HK450GT, just finished it and did test flight Sunday 3/13311. Flies very well, smooth and quiet. I basically ordered most of the stuff recommended by HK. I did make one change. Since I saw how the servos mount and they are a real pain to get in and out if you break a gear I ordered 3 metal gear servos just in case. I use a DX6i Tx and Rx. This allows me to tame it down so I can fly it. It took me 3 evenings to get it together. I downloaded the T-Rex 450 SE V2 manual and followed it for the build. I took pictures along the way and will post them when I get all the descriptions written. I am very pleased with the HK heli and will buy a second kit for backup. Hey for $54 you get a lot of spare parts.

Keep us posted on what you did.
