This is a repost that I made on Rotorworks.net

This is just a friendly suggestion...take it for what it is worth. :wink:

I had my Pro throw a tail blade last night and trashed my TR gearbox.

The blade that was thrown was still in the blade grip with an undamaged bolt through the grip bearing. The cause of this failure was not a part failure but an improper assembly IMO. Upon inspection the threads in the TR hub are fine as is the bolt...THERE WAS NO LOCKTITE :!:

I guess I took it for granted because the kit was mostly assembled that this was taken care of. This is something that would not have been overlooked by me had I put the kit together.(and it won't be overlooked again by me TRUST me)

I have not taken the other bolt from the hub yet as I want to take pictures of the aftermath before disassembling the remains.

Moral of the story guys is you probably need a dab of locktite here and there on this ARF.

Oh and by the way just because the parts are small they still can HURT :!: :roll:

When I bought mine one of the screw thats holds the blade grip onto the hub was loose too. I did tighten it, but i noticed after 5 or 6 flights one of them was loose again. This isn't like the elite or FP HB's. We got to check this heli over everytime we fly. Make yourself a check list so you can glance for cracks, or feel for tightnesses.

Oh I'd just like to add that the tail rotor system spins 5 times as fast as the main rotor blades. So if your main headspeed is 2700rpms then the tail blade are spinning at 13,500rpms.

I'd like to add that I always wear glasses when flying, especially micro helis. Seems silly to wear protective goggles when using the dremel, then take them off to fly!

Just got mine and it was missing the aft tail gearbox screw. Wasn't going to say anything on here, but, they never replied to my email. No big deal, just would've liked an "oops, our bad" at the least.

Compared to what I went through with my hornet 2, this thing has impressed me so far. Just wish I still had a good set of blades from the H2 to put on the pro

What do you like better about the HB Pro over the Hornet II?

Lowell, remember when i was talking to you about the play in the head system on the elite's? well the 3D pro is much better its a lot stiffer and more beefy.

Lowell,
1. The hornet wasn't a good beginner heli. Of course when I asked Helihobby, they said it was a great beginner heli. Yeah! For them. They made alot of money off of me.
2. MS parts are expensive. Most of my crashes weren't more than 2 feet off the ground and average cost per crash was about $60.
3. The 3Dpro feels alot sturdier. Spend $180 on a pro and compare to what you get for $215(some have it cheaper now) for the H2.
4. It's small things like:
a. clamps for the tail servo...not trying to CA a flat piece of plastic to a round shaft
b. clamp on horizontal fin and tail fin...see above.
c. better servo mounts
d. etc.....
I am far from being a good heli pilot and by no means an expert on building them...just giving my personal opinion.
