A bad weekend for flying

Well, it was going to happen sooner or later, my first crash of a Helicopter, and this weekend, it did.

I had bought myself a small electric Helicopter, these tend to be harder to control than the larger petrol ones, so figured it was a good thing to use to push myself a little more. hovering it was fine, I can do that, it’s not a problem. I had a day of flying on Saturday, having bought an extra battery for the electric, so I had 2 batteries for that, and got through a tank of fuel on the Nexus. having re-charged one of the batteries for the electric, I started to push a little more, I was doing small-low circuits with it before, this time I started going a bit faster, as it came in fast, I pulled back to slow it down, and the rotors hit the tail boom and down to the floor it came… it took me a moment to work out what had just happened, I’m still not sure why exactly it did that, as it shouldn’t. but new parts are ordered, that’s only £20 – and it should be flying again by Tuesday (internet orders, have to wait for delivery – ho humm) – all I can say is, I’m damn glad it wasn’t the Nexus, because then I’d have been seriously gutted. I just have to work out why it hit itself once it’s re-built.

On Sunday, I went back up the airfield, this time only with the Nexus. Neil gave me some spacers, so I could put my nice new Carbon Fibre rotor blades on – and they look really nice! once they were on, I had a quick hover, but there was a couple of issues, the tracking of the blades was out, and the head speed was too high, well first job is to get the tracking roughly right, with a guage, next step is to get the head speed slowed down, and then to finely adjust the tracking. while sorting the head speed (we wanted this at 1750 RPM – as this is “optimum” for these rotors) we got it right, and I made a mental note of the display of my receiver so I knew exactly where to set the “max” power. – if you’re interested that was 55% throttle. job done, so move the collective stick down and…. wait… it’s not doing anything… I have no control at all. The Heli had decided to turn the electrics off! so, my toy that I really enjoy was now a sitting duck, with rotors spinning at 1750 RPM, engine running, and no control! Neil ran round telling everyone that the machine was there and has no control, and all we could do was wait for it to run out of fuel… and 30 minutes later it finally did. fortunately the pitch was still too low for it to get off the ground, but had the wind picked up, it could have gone anywhere.

The good news is that I did get the settings for the head speed – though, this will change slightly once it’s in the air, and there’s some friction on the rotors. but it’s roughly there. I have sorted the switching off problem (seems the switch was faulty – and was hard to turn on, but very easy to turn off again – just a light touch and it went off, so it most likely vibrated to the “off” position.

Next I need to sort the tracking out, and check my Gyro. the Gyro has been a hard thing to setup, but little point in messing with it until everything is set up right, otherwise you only end up changing the gyro again. though, I might replace this with a better one before long.

all in all, a bad flying weekend. however. I learnt more. I stayed calm when there were big problems (and dangerous problems) and I’ve had my first crash. I’m sure there will be many many more, I just hope not with the Nexus!

Thanks to Neil for his help. was much appreciated.

Toys and Hobbys

Overtime, People go through lots of hobbys, and I’m no different. However, I rarely find a cheap hobby to do. I have done juggling and now everytime I’m in Camden I spend £100+ on things for that, though you don’t need to service them, that’s ok. I’ve taken to playing computer games, Guitar hero (mostly the drums) on the Wii and racing games and flight sims on the PC. The equipment to play games properly is also not cheap, you need a nice fast computer, plus the racing games I have a £180 steering wheel set. The Wii is pricey, the drums for the Guitar hero (with Guitar hero) was around £130 and before you know it you’ve spent a few thousand pounds on…. stuff.

Well, some years ago, I took to flying Model Helicopters, started with small ones, and sort-of worked up, I flew someone else’s helicopter, but not for very long, this one was a couple of feet long. I haven’t flown one for a while now, and I was talking about buying one again so I could go flying with it again. However the need to buy one has been shunted out. and here’s why…

DSCF1304 Yep, That’s right, I now have a Nexus 30 Helicopter, this has a petrol engine, and no, I won’t be flying this in the house. It did however need some work, This was my fathers, and he…. well…. crashed it. :-) This week has been delivery after delivery of very small parts and the rotor head has been re-built, it has new rotors, and is about ready to crash fly.

Basingstoke Model Flying Club have a field, that I will be at on Sunday, at least trying to fly this. though, it does still need some setting up, testing of the servos, the engine, and a few other checks too, it looks like I will have help in getting it through the checks, and air-born, hopefully some help trying to fly the thing too (I need a trainer).

I’m not scared of flying this. I am, however, scared of landing it, that’s the bit where it all goes wrong. This is going to A) be an expensive hobby, and B) going to take a very long time. I’m pretty sure I’m not going to get bored of this one very quickly, and even if I do, I’ll probably have a helicopter to build again.

Well, wish me luck on sunday for getting this thing off the ground, and safely back again.
