What a great day for me and my Tiger!! This is long winded and you'all might not want to read this whole thing, but I think some of you will appreciate it. I'm so excited, I needed to tell someone. I've had my Tiger for a little over a year. But I have yet to get through a gallon of fuel. And until tonight, I've only ever flown one tankful each time I flew. Either I crashed before a second tank or I was so nervous that I was afraid to do a second tank. But tonight was great. I joined a club here in Richmond. They have a nice field but no heliport and out of the 70 members in the club, I'm the only one who flies helis. So it makes it difficult to fly when I have to share the main runway with the plankers. But tonight was a very calm, relatively cool evening. So I drove to the field and found no one there. There was just a slight breeze. It was great. The last time I flew there, I got nervous because everyone was watching and they even filmed my flying. I got through most of a tank and then crash landed. It seems that every time I crash, its because I'm trying to do a nice, controlled landing and somehow mess it up. But with no one there, I could really concentrate. I hovered for a full tank, all orientations. I actually kept the hover pretty close to the ground, even when I was doing nose in. But, as expected, if the Tiger began to drift, I didn't have much time to react before I would end up in the weeds so I took it a little higher to practice hovering. I also practiced a lot of landings, but I always spun the Tiger around so I landed tail in. The only time I tried a side orientation landing, I pulled the stick the wrong way and tipped it over instead of straightening it up. So I've decided to stay with tail-in landings for awhile. But one thing I finally realized a couple of weeks ago is that my normal pitch curve was way too steep. I hover at 3/4 stick and have followed JB's approach from the manual. My curve was a straight line from midstick/0 degrees on the axis up to about +8 degrees of pitch. Below midstick, I had a gentle curve to about -3 degrees. I decided that I needed to smooth out the curve from -3 to +8 and not necessarily take it through 0. This resulted in a much softer landing which was easier for me to control. The Tiger doesn't drop now nearly as fast as when I had a steeper curve. I don't know why it took me so long to figure that out but when there is no one else in the club to talk to, I just didn't think about it. So tonight I ran 4 tanks through. I hovered for the first tank. The Tiger was so steady that it was almost scary. With the slight breeze coming head on, it just hung there without my fingers on the sticks. That was really impressive. So for the second tank, I did some forward flight and flipped the switch to idle-up1. I had never gone to idle-up before. I had the heli high in the air just to make sure I could recover if something unexpected happened. I found out that my normal pitch curve and my idle-up curve were slightly different. When I went to idle-up, the pitch at that point in the curve was less than at normal and the heli dropped. I quickly recovered and got it back up. I'm sure that's because I adjusted my normal curve to soften it near 0 and didn't adjust my idle-up curve quite enough. I also turned off the GY401 to see the impact on the tail. The tail drifted a little left. I adjusted the trim to correct. I'll adjust the linkage length before my next flight. Also, when flipping to idle-up, the governor kicked in. It increased the headspeed just a bit so I know it was working. I also now know that the headspeed in normal is OK. I'm still flying woodies so I have the headspeed set at 1750 in the governor at idle-up1. Its not engaged at all in Normal. Now I'm really feeling good. I'm on my third tank and doing pretty good in fast forward flight. So I decided it was time to do a barrel roll. Had the Tiger pretty high and did one roll. Not pretty, but it worked. I have the Tiger set up for novice flying (long flybar, heavy paddles with weights, etc.) But it still worked fine. But after 2 rolls I decided not to push it. I also used my 9CHP to time how long I had on a tank of fuel. It looks like I can get 12 minutes on a tank and just start into the header tank. I'm not ready to cut it any closer. And when I start flying more FF, it will probably be less than that. But I did thin out my hyper a couple of clicks. I remember in one of JBs earlier posts that he said the hyper runs best at about 200 degrees. Even after a full tank of just hovering, I was still only reading about 115-120 degrees. So I figure I can lean it out a little more. But with not even a gallon through it yet, it probably could use a little more breaking-in. I was so focused on flying that I didn't really notice the bugs or mosquitos. But when I finished and was cleaning up the Tiger, I cleaned lots of bug juice off the rotor and paddles. It was relatively cool this late in the evening but I had broken a pretty good sweat. What a great day and what a great heli. I just need to find more time to fly. And by the way, no order for parts this week!!
