Chipping away

Hovering the EXI 450 in the garage...

The weather improved, but I wasn't able to get out to a field, so I hovered in the garage. The EXI is still having blade tracking problems, but the CCPM and cage are set up sweet; I have never figured this one out and have wondered if its something in the blades themselves. Well, don't you know, I get to find out... In hovering, I brought her down near the trash can, she bounced and just winged the can, but this chipped the ends of the blades enough to delaminate them. And I had just been wondering how I have had this heli for months and she still had her original blades!

I put some new fiberglass ones on, rechecked the CCPM and everything looks good. The Feathering shaft and the main rotor are fine. these blades were nicely balanced out of the bag.

I hope the tracking issue is gone with the new blades. It was off about 0.5 cm at mid throttle, even with a nicely tuned CCPM. The feathering shaft is straight and the pitch is right on. We'll see if these new blades resolve the issue. I plan to fly a few packs tomorrow! The weather looks good! I am excited to get her out.

Frankenheli

I am wondering if Frankenheli should get the 4 blade rotor head? The larger rotor disk will stabilize her more being that I won't have a FBL system in, though I have been toying with the idea of getting a BeastX for her. It would be one way to get a stabilized flybarless heli without buying a two blade FBL head. Hmmm...

Gyros!

I am excited that Hobby King has shipped my GA-250 mini-MEMS gyros. These little pretties are getting good press as a $10 MEMS gyro, a relabel of an Assan gyro. Yup, $10! I had mine backordered, and they are already NIS! I need to think about getting a few of these little puppies!  BUT WAIT!  Looky at what I found when I went to get the link for the GA-250s!  HK has another MEMS gyro, a programmable one, for $70! The Turnigy mini-MEMS with programming box. Very nice... Must consider...  I had purchased another Detrum GY48V, an inexpensive piezo, but of course the moment I ordered it I got the email telling me HK was shipping by backordered MEMS. A guy on Helifreak crashed his Blade 400, and being on some tough times he was upset about the crash and not being able to fix it. While he wasn't seeking sympathy, the HF's banded together around him and he is essentially receiving a new Blade 400 in parts pieces! I am sending him what he needs for a Milton Mod (which I am trying on my 250, and my other helis as well probably), and will be including that GY48V, since I don't need it. very happy for him!
