Ok so I have run about 6 tanks through my heli over the weekend. 4 of them were just scooting around my garden, just skimming the ground. Then I took it up the park and managed a few hovers for a couple of tanks worth.

As it was all brand new I started out with the fuel mixture at 3 turns out, started it very easy and it ran fine. But was chucking out shed loads of smoke.

The heli, training gear and anything near by completely covered in a film of fuel. When I was in the model shop buying the fuel & I asked the guy the best way to fill it, he said put a fuel filter in the line and just pull off one side and fit you hand winder on the other. What a F'ING POS, the bloody thing just pissed fuel every where so I slung it and went back to one bit of pipe, much better!

As im learning I have the pitch range set at 0 +5 +9 (+5 at centre stick) & throttle curve 20, 40, 50, 60, 100% but the heli seems to hover at about 3/4 stick. I figured the head speed was prob low so on the 5th tank I leaned it out a few clicks and it was a bit better so I ran it for a min and gave it the touch test, only mildly warm so I leaned it out to 2 1/2 turns out and spooled her up. Well the hover was still above centre stick but just before it took off the engine note changed from a low sounding splutter to a much higher pitch / crisper sound. The heli seemed to behave much better after that.

I though about dialling in some more power on the throttle curve but I have it all setup as stated on raptor technique so I didn't think that was the answer.

Is it ok to start leaning out the mixture after 6 tanks?
What's the best was to check the rx battery power? If I flew a couple of tanks one day should I charge the pack before the next flight?

Cheers ears...

You might want to think about getting a 3 way fuel filter....it makes filling up the tank much easier. this is an old pic of mine

newbie also

The local heli "expert" had me run a full two gallons thru mine before leaning it ( thats about 18 flights on my rap50). He said its better for the engine, but I've heard about 50 different break-in techniques so I'm not sure which ones right. As far as batteries I have a Rap50,JR6102,standard servos,GY401 with a digital servo, OS 50 I get about 4 maybe 5 flights before charging. My transmitter seems to get low before my flight pack. The transmitter has a voltage on it and I bought a little meter that plugs into my reciever pack to show when the voltage is getting low. It was $12 at the LHS.

For onboard voltage I got this thing called a voltwatch and stuck it to the back of my tail servo so I can see it all the time works great only about five flights out of a 2100mah pack and TX in a bout two to three hours of flight get my gallery for pics of the voltwatch and my fueling fix

Don't lean it too quickly. You should be able to leave your finger on the backplate almost indefinately when breaking that motor in. You don't need a bunch of extra power to learn to hover... Keep the motor rich and happy. Gallon two is a better place to SLOWLY get the temp up a bit.

You can get an onboard volt meter to track your Rx voltage. Voltwatch, Gem, or 1000 other generic ones. The other way to go is with a handheld voltage checker. This will put a load on the battery and give you a more accurate reading. Most of the better chargers will put a good load (1 amp) on the battery and show the voltage on a discharge cycle.

With standard servos and gentle flying you will typically draw less than 250mah per flight. After 2-3 flights you should be thinking about field charging unless you have a large battery pack. Normally when the voltage gets a little low you will feel the tail get weak and not hold as well. That is a pretty significant danger sign.

Good Luck,

Mike
