When RC Helicopters Collide
Friday, September 10th, 2010
I trained my friend with a buddy box (LP5DSM) and my DX7 on the E-Flite Blade mSR. Not a single crash and he was ready by himself. He took it by himself and flew it nose out, take off, and land, without crashing. Not bad from only flying coaxial micro RC helicopters. I had my Blade CX2 so I started flying at the same time. We were pretty good hovering them beside each other. Many flights later it happened, they collided. Surprisingly, the Blade mSR won the battle. The Blade CX2 top blade smashed, i think the canopy, of the Blade mSR causing the blade to snap at the end. The Blade mSR, not a scratch. Cool.

I’ve flown the Blade mSR everywhere for the past couple of months and I’ve yet to replace a part. It’s had several careful crashes and falls. The blades are scratched but not cut. I’ve had to clean the motors a few times but other than that it’s been perfect. I would still suggest the Blade CX2 if you want to start flying RC helicopters because it has more power for controlled flight and crashing once will most likely brake it so you’ll try harder to fly with control.

RC Helicotpers – 1 Month Summary
Tuesday, August 3rd, 2010
I’ve been flying a few days a week for just over a month now. I’ve been using E-Flite models starting with the Blade CX2 then moving to the Blade SR and the Blade mSR. I started practicing with training wheels and the phoenix flight simulator. I was quick to pick it up and I’m able to push the CX2 to its limits without problems. You can only go so fast with the coaxial models so I upgraded to the Blade SR and picked up an mSR on the side.

The E-Flite Blade CX2 got me started. I bought the RTF kit, extra battery and training gear. I was off the ground first go but only for a few seconds hover. I spent 1 week hovering and moving forward/backward left/right nose out. If you’re lucky to get a windless day take it outside and give yourself some playing room. The Blade CX2 is simple to correct if you lose control. Watch the wind. Even if the trees aren’t blowing there could be small small gusts that will affect the flight. Adding extra weight to the nose and moving the battery forward will help outdoor flights. I’ve crashed the CX2 a few times. I’ve replaced blades, skids, and one crash took out my canopy so I had an excuse to get another one. The main shaft is very slightly bent and noticeable at full throttle but it hasn’t affected the helicopter enough to need replacing. That will be the next repair.

The E-Flite Blade SR got me started on single rotor RC helicopters. I also got the training gear. The Phoenix RC Flight Simulator has the full line of E-Flite models so I flew the Blade SR for a few hours on the Sim before taking it out. My maiden flight was a success and I’ve been practicing basic forward/backward left/right movements nose out. I felt I was comfortable so I tried a simple circle. I ended up correcting a problem the wrong way and smashed it into the ground. I broke the blades, training gear, main gear, tail rod, and blew the tail motor. Fun, and I’ll have more fun undoing the solder to rewire the tail motor…

The E-Flite Blade mSR is the micro version of the Blade SR and my latest addition. It’s basically a very small single rotor helicopter and it’s fully loaded. I got the Bind and Fly kit meaning I can use my existing transmitter to control the Blade mSR. The maiden flight was the best one I’ve had yet. Out of the box, the Blade mSR was performing very well with my limited flying experience. I could fly it comfortably (nose out) in all directions. I brought the helicopter outside and played around with orientation. After just 2 days I’m very comfortable hovering and spot landing it. I own a handful of micro helicopters but the Blade mSR destroys them. If you like booting around every now and then indoors then this is the model for you. Spend the extra money and get into a real micro RC Helicopter.

Progress Report – Week 3
Tuesday, June 22nd, 2010
I’ve had a good 2 weeks with the Blade CX2. I’ve had several flights outside and inside with two crashes to date. One crash was small but the blades knocked and broke them all. The other crash was fast, watch the video, and bent the main shaft slightly but not enough to throw it off.

My swashplate wasn’t level, so I’ve made adjustments to the server arms and pushrods and trimmed the weird rudder movement with the pot on the controller. With all trims centered the helicopter hovers to the best of my abilities. Trimming took a while. You have to make the minor adjustments by disassembling then reassembling for testing. Put a few hours aside if it’s way off, or if you’ve overcorrected by accident. I messed up so be careful. Make very small adjustments, half turns for the server pushrods and very very small turns on the controller pots.

Outside is fun if it’s not windy. There are a few problems with the wind that really take down the Blade CX2. First is the design. It’s not meant for outdoor flight because the model doesn’t have a rudder and the coaxial blades just can’t cut the wind. But it’s definitely not impossible. Try flying with the wind and maybe trim some forward cyclic. The rudder will swing if the wind hits it so have good orientation, my 3 weeks is ok in calm calm wind. I’ve gotten in going pretty fast with a little wind, but I’ve had to slow it down fast by swinging the rudder in the opposite direction giving throttle and correcting. Be prepared for the worst because you’re already taking risks being outside if this is your first helicopter.

Until next time…

How To Level The Swashplate
Tuesday, June 15th, 2010
So I got my E-Flight Blade CX2 Ready To Fly (RTF out of the box), and it wasn’t so RTF. I made a big mistake and not figure out the workings of the helicopter before flying it. I noticed I had to use a lot of right rudder trim to compensate the left rudder movement. It definitely wasn’t normal, so I took the helicopter apart and noticed everything was off!

I had one crash before the adjustment, but I’m convinced it was shipped this way from day 1. The swashplate isn’t level, and the servo pushrod isn’t 90 degrees to the server arm. There was quite a difference when I moved the server pushrod on the second notch, but not perfect enough to level the swashplate.

I had a big problem. After I made the adjustments I thought everything was level, it was not, in fact it wasn’t even capable of taking off at this point. I always underestimate this helicopter thinking you can just whiz by a couple forum posts and fix everything. These are delicate machines, even the blade cx2, and you have to understand exactly what does what so you fix it. So far everything I’ve tried has failed multiple times and that just sucks. I’m not giving up. So when I got home today I went back to the books and read everything over and over again. In the end, with only about 2 hours of research and work on swashplate leveling, I was hovering better then ever, and much better then out of the box. The best I can do is trim 2 clicks left rudder for perfect hover .

How I fixed a serious left nose rudder drift, elevator and aileron drift.
I made a great mistake and seriously destroyed the balance of my helicopter by doing everything wrong to fix a minor drift. I’m sorry I won’t get into too much technical detail so watch the video for more info.

Adjusting Rudder Drift
The Main Motor Proportional Mix Trimmer Pot can be found on the left side of the control unit. This “proportional” trimmer pot adjusts the amount of mixing between the main motors allowing you to fine-tune the rudder trim (sub-trim) to help prevent the nose from drifting to the left or right when in hover.

Note the direction the nose of the helicopter is trying to drift with the rudder trim centered and no rudder input.
Power off and remove the shell of the helicopter.
Turn the Main Motor Proportional Mix in the rotation required to correct the drift. If the nose is drifting to the left, you will want to increase power to the right-hand motor (spinning the upper main rotor blade), by turning the Proportional trimmer pot clockwise (+).
Hover the helicopter and make finer adjustments as needed.
Adjusting Elevator (forward/backward) Drift – The Swashplate
If your helicopter is drifting forward or backward you can first take a look at the elevator server arm and pushrod and make sure the swashplate is level. If your helicopter is also drifting left and right, adjust the aileron server after the elevator. Why? Because this process works great for me and I’m sticking to it.

Remove the shell. Center the trims and power on the transmitter, then plug in the battery to the helicopter. You want to make these adjustments while it is turned on so the servos stay centered. Unplug the motor power for safety.
Align the server arm with server pushrod. The elevator servo is on the right of the helicopter looking from the back. First you will want to check if the servo pushrod and arm are 90 to each other. If they aren’t then you will need to move the pushrod into another hole in the arm. First, remove the screw holding the arm in, pull off the arm and disconnect the pushrod. Put it back in the opposite order.
Align the swashplate. You can eyeball this but it’s best to hover the helicopter and make small adjustments. If you were to eyeball it, good luck, just make sure the swashplate is level in relation to the rotational plane of the main rotor blades.
Hover the helicopter and make finer adjustments as needed.
Adjusting Elevator (forward/backward) Drift – The Swashplate
If your helicopter is drifting left or right, use the same method here just on the opposite server. From looking at the back of the helicopter the aileron server is on the right.

Remove the shell. Center the trims and power on the transmitter, then plug in the battery to the helicopter. You want to make these adjustments while it is turned on so the servos stay centered. Unplug the motor power for safety.
Align server arm with server pushrod. The aileron servo is on the right of the helicopter looking from the back. First you will want to check if the servo pushrod and arm are 90 to each other. If they aren’t then you will need to move the pushrod into another hole in the arm. First, remove the screw holding the arm in, pull off the arm and disconnect the pushrod. Put it back in the opposite order.
Align the swashplate by removing the server pushrod and extending or screwing in the metal connector. Your smallest adjustment can be 1/2 turn. Again, I wouldn’t recommend the eyeball method to align it.
Hover the helicopter and make finer adjustments as needed.
Let me know if you’ve got any questions and I’ll try to answer them.

Good luck!
