R/C heli flying

I took my newly acquired Align Trex 450SE V2 out today for its first proper flight (other than hovering in the back yard to make sure everything was working properly). Man.....I'm certainly rusty! But, I suppose that's to be expected, having not flown a heli in over 2 years. It's definitely going to be a long road back to where my skill level was at before I quit :-(

Bad vibrations.......

I've been doing quite a bit of r/c helicopter flying of late, now that I have a shiny new OS .50 Hyper engine in it.......can you say 'power'? :) Unfortunately though, my helicopter has suddenly decided it's going to try to shake itself to pieces in the air. I've picked up a rather annoying vibration problem that's had me stumped trying to fix it. I've replaced (in no particular order).......
Mainshaft,
Tail output shaft,
Tail blade hub,
Clutch shoe assy,
Cooling fan (I got the shiny bling K&S one.....it's niiiiice),
Tail pitch slider assy (some more K&S bling)
Washout assy (yet *more* K&S bling!)

All of that to no avail....other than adding significant cost to the upgrades I've got on this thing. BUT.....last night while I was refitting the engine after painting the back of the new cooling fan black (so my new optical govenor sensor wouldn't get confused and keep turning itself off in mid flight), I discovered that I have a wobbly clutch bell. So, having replaced a whole pile of bits that didn't need replacing, I think I just might have *finally* worked out where the vibes are coming from.

I'm now waiting for some more 'upgrades' to replace those bits :-)

First R/C flights in 2 years!

Given that I'm not going to be able to kitesurf again until next season (thanks to my wrist tendonitis), I decided that I might dig out my radio controlled planes and helicopter for something to fill my spare time. I dragged them out and checked all the gear out, only to discover that the receiver pack in the helicopter had give up the ghost. Everything else seemed to be perfectly fine though, much to my surprise, considering I hadn't bothered to cycle any of the packs while they were in storage. Nor did I do any storage preparation on my engines.

Anyway, I replaced the receiver pack and gave the heli engine a quick test run in the back yard the other day and it ran fine, so I took it all to work with me the following day so I could go flying after work. Of course, it rained the next day. I went to the field anyway and had to stand around for nearly 2 hours waiting for the rain to stop. When it finally did, I got organised to fly but for some reason the engine decided it was going to play up on me and not run past about 1/3 throttle without suddenly stopping. It did this about 5 times, after which it started to rain again anyway, so I went home.

Next day, I decided I would try to sort out why the engine wouldn't run. I had it in the yard again, trying to start it, and my power panel blew up. No warning....just suddenly died. So, I went to get another one from the hobby shop. By the time I got home, it was too late to try again though. So, I packed the car for a day at the field today instead. When I got there and tried to start the heli, the brand new power panel also blew up! Not having much luck here! So, not to be dissuaded, I hunted around in my car until I found a couple of 1.5v batteries. With some electrical tape, 2 banana plugs and some aligator clips, I had myself a makeshift glow plug igniter :-) It worked a treat, so I was *finally* able to get airborne.

I tell you what.....after 2 years of not flying anything, you certainly get a case of nerves when you lift off with the helicopter!! But, after a couple of flights my thumbs remembered what to do and all was well. I took my World Models Super Sports Senior to the field with me too. No such problems with the YS.91FZ.....started immediately and ran like it had never been sitting in a room for 2 years under a sheet. I hope the YS1.10FZ in my Ultimate Bipe behaves as well when I head out later in the week with it!

What a fantastic afternoon too....clear blue skies and light winds. All in all, a very enjoyable afternoon :-)
