Fellow Freaks,
Well I took my first flights with my new Titan Friday. Wow what a machine! Being my first nitro heli I was pretty intimidated by flying such a big machine (compared to a T-Rex). But once it was in the air it was awesome! Very-very stable, very easy to fly, and very easy to see (again compared to a T-Rex).
I did have one issue that concerned me. During spool-up the Titan started oscillating left to right for a few seconds (it got kind of violent actually) then settled back down as it continued to spool. I thought it was the blades, crooked in the grips, then straitening out. However after a bit of flying around and landing it did it again during spool-down. It seems to only occur if I slowly spool-up or down. If I land and hit throttle-hold it doesn’t do it. I tightened the blade grips a bit and that got rid of the problem during spool-down, but still does it during spool-up….. Blades are balanced, fly-bar and paddles balanced, everything seems to be fine mechanically, just wobbles during spool-up… Any ideas or insight on this?
So, occultation problem aside, I was out flying Saturday and was forced to do my first Auto-Rotation! I had just done a big turn and was flying back towards myself when the motor (an OS non-hyper hand-me-down from a friend) seized; forcing me to auto in from 35 feet up!! So I did my first auto and first nose-in landing all at once!! Everything turned out ok, the Titan returned to the ground without injury. Whew!!
Let me know what you guys think…
Thanks!

By the way... Will the stock gear ratio work for my new Hyper 50?
Thanks!

Stock ratio is fine for the Hyper 50, but the optional 8.727 gearing will allow you you to get more power out of the hyper at a lower head speed. i see no real downside to it really that i have seen. i have not ben able to bog my heli since i added it.

I fly with my multigov set at 1950.

DS are you running 600 or 620's. I've got the gears, just havent gotten around to putting them in yet.

Thanks for the input guys! I'm assuming that I can get the gears from HeliProz....? By the way I'm running 600's and am NOT Joe-3D flyer.
I think I solved the oscillation issue… Blades were too loose and not tightened evenly.

One more question; What's a good pipe for the Hyper that's not as loud as the TT pipe?

BarracudaHockey, I actually introduced myself to you in Mulberry if you remember. We were watching the large scale electrics fly... You were right, I Love the Titan!

Thanks,
Jimmy D

What is that part number.. do you change the pinion and maingear?

PV0518 You have to change the pinion and the main, it changes the gear ratio from 8.5 to 8.7 something. Now 17K on the engine gives you 1950 vice 2000

Yep Jimmy I remember, it was nice meeting you.
