Nitro vs Electric at 3D Masters 2010

No Gravatar

At the 3D master i decided to try to count the number of nitro helicopters and the number of electric helicopters, and i did that more or less as promised, i installed an application on my android phone for editing excel document and i updated the document every hour or so and the result you can see here:

Nitro flights Electric flights
82 flights 17 flights

Nitro still is the dominating choice, but it is just a question of time i am sure, you can’t see any difference in flight style between the two. Only how long the flight lasts.

The results are not scientific. :)

I am starting to get ready to go to 3D Masters, packing the car charging the batteries for the cameras. I really can’t wait I am sure it is going to be great, I am planning on make some statistics of the amount of nitro and electric helicopter this weekend, just for the fun of it.

And like I already have told you I am planning to keep you updated live from my phone, keep your eyes open for updates on http://rcheli.dk

WUUUUUHUUU I am back, on the internet that is, I changed internet provider and because of that i had to wait for a new internet connection for about 3 weeks, bummer, but I can save some money on the new internet deal and that money I can use for Fuel, look I made a chart, I am a big boy.

Here are the prices for 30% nitro fuel recommended for RC helicopter, prices are in Danish kroner. I compared the prices in liter.

If I forgot somebody, or if you have a good/cheap place to buy fuel, feel free to write a comment to keep me updated, then I will update the chart.

Can I at the same time encourage you guys in the other country’s to make the same kind of chart to urge for some price competition, I will link to your price comparison


The Pitchbrother society

First of all, let me just start out with confirming that I am NOT a member of the Pitchbrother society, I am way too happy with my helicopter.

The definition of a Pitchbrother: Well to put it frank, you have to rape your helicopter like there is no tomorrow, that’s true, fly that baby as low as you can, and make those blades green with grass. That’s a Pitchbrother, interested in being a member? Well if you can prove it with a picture or a video, then you can be a member and get a Pitchbrother sticker :) AND it has to be a nitro helicopter, THAT’S the rules.

If you’re interested post a comment here with a link to your Pitchbrother evidence.

And here is a video with one of the founders of the Pitchbrother society.


Wasting two gallons CoolPower

No Gravatar

I just had a great heli weekend, I got two days of flying, and that’s not common for me, but it’s with great sorrow that I had to see the weekend fly away with fine tuning the engine.

I have never been very good at tuning my engine, and I know that. The first day I was flying I did know that some tuning had to be done, I change the fuel brand from HeliMix to Coolpower. With that change of fuel brand some engine tuning has to be expected. But I am very sorry to conclude that my engine was not running well at all with the HeliMix the engine was setup completely wrong, and I am the only one to blame. And it was first when I changed to CoolPower that I could feel and hear that the engine was not running correct at all. :(

First Gallon:
Well the first day went okay, I did try to tune the engine and at the end of the gallon it seemed like the engine was running okay, but I still had some issues when I gave it full throttle, it was running kind of nervous, but it was running better then when the day started.

Second Gallon:
Next day was very disappointing, first time I started the helicopter I could hear that the engine was not running the way it was suppose to, it really got me in the red zoon. But hey I was ad it again, trying to tune the engine, with no luck. But to my advantage a fellow pilot came by the field without he’s helicopters and he helped me out, then the engine started to run a lot better, very nice indeed.
But it was still running a bit nervous with full throttle.
The fellow pilot told me that he had the same issues with he’s OS 91 SZ until he mounted all the O-Rings in the engine, with all O-Ring’s at 0,5mm the engine should not run nervous with full throttle.
Well I mounted one more O-ring in the engine and now I have 0,4mm thick ring. And I can’t way to get to the field and try it out, I hope this works because if not, I am seriously considering to changing the whole think to an electric Helicopter. But I hope it works, because I am going to miss the smell of burned fuel.

Wish me luck.

And by the way, I was running HeliMix 15% nitro, and now I am running CoolPower 10% nitro, my local hobby store could not deliver HeliMix as fast as I was hoping and that’s why I changed fuel brands, I am not saying that HeliMix is a pure product, I am simply saying that I didn’t setup my engine correct with that fuel.
