It was blowing 8 to 10 when I got to the field. The heavy snow from Monday had melted making it a little muddy but I thought it was doable. I tied a bridal to the C lines in the middle of the right side of the wing. The camera would come up and swing into the lines every time. It was hard to tell if I had enough tether to get the camera flying in the right spot without going into the prop, but it looked right.
The launch was a mess. The wind, that had been blowing hard, came down dramatically. I set up the wing and took great care to prevent the camera from crossing any lines. Well, … while I was setting up, the wind shifted. I wasn’t aware of it because, (like a dummy), I’d put up the wind sock by the truck instead of out where I could see it from the trike. Needless to say the wing came up hard to the left and I had to abort. I reset in nil wind.and blew it again because the wind had come up from the wrong direction just as I started my run. This happened one more time before the wind settled down and I was able to get up.
I could see that the camera was flying off my right shoulder but I could also see that it was swinging left. and right. The are was mixing and bumpy so maybe that was it.
When I got home and viewed the video the camera was positioned well but the swing was not acceptable.
Maybe Mike will have an idea when I visit him on Sat.
Mike Bennett and & arrived at 6:30. It was much better than yesterdays rain/mist, there was a fresh 7mph breeze from the SSW and clear blue skies.
Trying to solve the chest pain I have made some modifications and this was the first time to try them out. In order to position my arms farther forward I have moved the hangpoints 1 inch and to rebalance the rig, Mike and I mounted a 12 pound weight over the front wheel. The brake lines have been lenghtened 3 inches and the brake pulley was lowered by the same amount and drawn in closer to the riser.
I will have to heal before I know if the problem has been fixed but I think I’m on the right track. It was definitely more comfortable and the pain is no worse. The next step will be to remount the battery forward of the seat this will not ad weight to the rig but allow the hang points to be moved another inch forward. Then I’ll play with the seat mount to get it dialed in.
Mike and I flew into the wind SSW and overflew the old ICBM Missile Silos. The wind speed increased dramatically with altitude. Mike flew low and I flew 400 feet higher at a much lower speed. For the first time I flew with the trimmers out and enjoyed the Eden III ‘s much crisper response. On the return leg downwind I exceeded 50 mph.
After a short break I went up again. The last several flights have all been higher wind and its been a good experience. The Eden comes up fast and sometimes pulls the trike back a couple of feet in the process but with a smooth surface it feels natural. The wing comes overhead … I ad throttle, start the roll and usually rotate within 50 feet. On soft terrain (sand) or worse…. bumpy (pasture) it may not be so easy. On this flight I stayed close to the patch and worked on steering. It is still not as comfortable as the trike buggy because I do not have the same range of motion. I don’t seem to have the power and it feels like I’m using different muscles. I can’t quite put my finger on the difference but I’ll work on it.
Paul M arrived just before I finished the second flight, so I decided to go for three. It was starting to get thermic and was most bumpy over by the farm houses so I flew out to the gun range and crabbed back to the LZ. The winds at the surface were twitchy as hell and I had to go around twice before I felt good to land. Two of the three landings I popped a wheeley after touch down. Next time I’m NOT going to kill the engine at two feet but will either go in dead stick or under power and taxi. It was a good day.
This was an interesting flight. I didn’t plan on flying tonight but I glad I did. The air was smooth and the breeze was light. Marek and I flew south over the open fields. We are both a little wary of the massive group of high Power lines and got plenty high to cross the 5 sets of parallel wires. It was similar to this morning with Greg. I stayed high and shadowed the pilot down low. Both Marek and Greg are pleasure to watch Greg with great wing control.
I moved the hang point rings to a horizontal position attempting to lesson the friction on the trim tab. No Joy…the problem is in the webbing that acts as a back-up in case the ring brakes loose from the bullet bar. I’ve replaced the heavy webbing with a slightly lighter and longer one which will hang loose over the risers and hopefully I’ll be able to use the trim tabs. If I end up hanging from the reserve or the H.P. ring brakes, the hangpoint will spread about two inches but I don’t think it will adversely affect how the buggy hangs or the how wing flys. The next flight will tell allot.
The wing came up crooked again but, like yesterday, it stabilized quickly. I think I’m not lining up square with the wind. I did notice that when I went from idle to full power the front wheel would dip about 6 inches and return to about 3 inches below the starting position. I expect that it will be even more pronounced when I am able to use the trimmers. I’ll move the H.P. Rings forward 3/8ths and see if It helps with the wheelbarrow effect.
The incident of the evening came as we were returning to the field. Marek’s hero camera came off it’s mount on top of the cage and went through the prop. He landed without issues in the LZ but was a long walk from the car. I knew something was wrong so I landed by the truck and walked out to meet him. We wandered around the field finding parts of the prop and eventually found the camera. Up on top is probably a good position for the camera but the vibration was working the mounting bolts loose…some lock tight would help if it does not have to be changed after every flight. I hope Marek got video all the way back to earth but I’m betting it stopped when it got whacked by the prop.
The skies were ugly this afternoon so I used the time to try an idea I got from Johnny Fetz.
What I did was add a pulley to the foot steering line. It increases the travel by 50% it also increases the friction but I don’t think it will be a show stopper, I can hardly wait to see how it flies.
I had an e-mail conversation with Alex Varv yesterday he is sending me a set of filters for the airbox. NO CHARGE! Nice Guy.
Added some length to the tubing on the bungee holding the bottom of the air box to keep it away from the offending nut.
