Compy 300: general messing around


This is my new Compy 300! Manufacturer's website is www.compy300.com, and I purchased mine from Albert at www.aero-fever.com in Hong Kong. Shipping is fast and not unreasonably priced either. There is a Compy build thread here:

https://www.rcgroups.com/forums/showthread.php?t=611407

My Compy weighs 420 grams and is equipped with:

ARC 20-34-130 motor from www.lightflightrc.com, 8T pinion
Castle Phoenix 25 (using governor mode with latest firmware)
Park BEC
BMS-306BB servos on swash
HS-50 servo on tail
TP 1320 battery

Enjoy the video.

-Chris

EDIT: I have determined why the gear whine was so loud! It was due to improper mesh on the main/pinion gear. It has been corrected and no longer makes such a ratty sound. Here's a short clip with the re-meshed gears. Even with the fence behind it to bounce the sound back to the camera, and with a slightly damaged pinion gear, it is much quieter!

It looks really smooth. I like! Seems like it flies much better than the CP2

You know, it really is smooth. It does have the friendly personality of the CP2, but with a wicked fast and deadly accurate tail. Mechanically the Compy is somewhat of a cross between a CP2 and a T-Rex, so not surprisingly it pretty much flies like you would expect such a creation to fly.

Thanks!

The performance of the Compy will surpass that of any King I've seen. It uses (or can use) the same motor, but it weighs about 100 grams less than most Kings. And the tail (being a T-Rex tail system) is super-precise and fast. It also just has a much nicer control feel than the King, IMO.

Considering this is a "version 1" that has only been on the market a few months, it is a remarkably well sorted package. It's only going to get better!

Excellent video, a real demo, not a quick flip over and inverted hover that leaves how the heli flies to the imagination. Maybe you should do Demos for Hire.

Thanks, CH! I tried to show how it does in regular flight. I'm not a "hardcore 3D" guy and probably never will be, so I tend to fly more "warbird style" with my helis. You know, just lots of fast passes, stall turns, loops and rolls. Since that was my first day out with the Compy I didn't do any acro, but I could tell by the power and control available that it'll do nicely for the "soft acro" that I prefer.

Hey, maybe some manufacturer will see this thread and hire me as a demo pilot for the non-3D crowd.

Don't feel bad, Cityflyer. We all probably spent too much on our Blades / CP2's, all trying to achieve what the Compy does right out of the box.

The great part is, all your Blade head parts will fit the Compy's main shaft, so you can keep those spares.

I know... I'm not helping, am I?

Thanks Chris! You really bring a lot to us here on RCGroups. Thanks to Liz too for her great video and support.

This looks like a nice heli for the money. How much would you say you have in the total gear?

Thanks for the kind words!

The airframe + autorotation gear upgrade is about $100, the motor + ESC combo is about $70, there's 4 servos for about $60, and a Telebee gyro at about $60. Oh, and a Park BEC at $20. So that's about $310, plus your receiver and transmitter. To put it another way, it's only about $75 more than I have invested in my brushless CP2!
