Nano has the hiccups


My nano has a pitch pulse(servo pulse) the nano jumps about one inch at about mid stick sometimes when i increase throttle sometimes dropping throttle it's all three servos, every once in awhile not to often it will pitch pulse and jump up or down maybe an inch then shoot off to the right like I jammed the ailerons full right. Also maybe at the same time something happens with the tail I can't tell if it bobs from the pitch change or the tail motor pulses the tail doesn't swing it stays straight I'm not sure whats happening there and it doesn't happen as . I have checked every thing main gear was my first thought with the jumping its tight, spindle straight and has some play, blades loose, good batteries, only about 20 flight's normal mode, no crashes, no vibrations. tried both sets of blades. Dx6i setup per manual, pitch curves per manual, throttle curves per manual,
I have a video below I'm holding it but you can see the servos jump and not sure if it happens in idleup just can't tell. I called horizon today and they told me to clean my aileron servo and no go called them back and it will be sent back for repairs. did a search in the thread and didn't find anything. Thought I would see if any ideas here

Do you guys (those of us that are still learning) fly with your finger hovering over the thr hold basically whenever you aren't totally sure you are fine? I am finding that is the only way I can hit it quick enough. It is a new thing for me to hit thr hld instead of cutting the throttle so its taking some retraining of my poor brain

Just practice using the switch when you are not actually flying... or practice on a SIM if you have one... it is always best to practice something new on a SIM first before trying it in real life. Even way back when I was flying the MCX2 I always used throttle hold... so I do not think much about it. Transmitter might make a difference too, I have a DX8 and the throttle hold is very easy to hit with out too much thought.

Is your flying area too small or what exactly is the situation you keep finding yourself in that makes you feel the need to "hover" over the switch?

AH - it's not an uncommon problem. You've got dirty servos my fiend! The tracks behind the fingers need cleaning -

You can clean them with:
1. Deoxit spray and then follow up with their lube.
2. Motor cleaner spray that's plastic-friendly.
3. Take the servo off its board, and use a pink eraser to clean the tracks. Don't bother touching the fingers as they are very delicate and tiny.

Hope that help you out!

You are a "go" for reentry

I don't have the 4 RTF radio but I would assume its like the normal training switch switch button. You don't hover over it your pinky or ring finger should be on it ready to press if it starts getting away from you.
Reaction time improves with practice but hitting throttle hold wasn't the harder thing for me. It was feathering the throttle up to increase the blade pitch and not cut the throttle. Cut the throttle and the blade pitch is usually in the wrong direction throwing you to the ground.

I'm a good pilot, and although no 3D yet, I too always have my finger at the ready on the TC switch. My nCP Xs are the fastest things I've flown to date!

Finally somebody is set to answer my calls:

Rakon just announced the frame for the nano !!! (Yipppppeeeeeh!!)
http://rakonheli.com/rkh/index.php?p...emart&Itemid=1

however, the price is probably going to derail that idea still for a bit into the new year
(why does it always HAVE to be so costly to be early adopter? ...)

Anyway, hope they also put some pics up soon ...

I saw that as well on their web site yesterday. I sure hope the designers over at RKH know what they're doing, because the nCP X is a full 3D heli and will crash. If the main frame's CF parts are wafer thin like the 120SR's RKH frame, then I'll pass. It won't be able to withstand the abuse we put these things through like the stock frame does.

Well, if the RKH should not be "your cup of tea" you still got a chance with microheli (as they wont take long to offer a frame now themselves - at least anything but this would be to the highest degree surprising)
I tried all 3 upgrade frames for the mcpx, and as much as I like the rakon, I got to the conclusion that the MH frame is best for me (and I think its ultimately the most well thought through of the 3)
Anyway, I got the aftermarket frames mostly because those darn canopy posts keep breaking when the wind blows wrong at them - and for that purpose they were a good investment (in particular the MH, which I already crashed bad multipe times ... even WITHOUT 3D .)

It's not clear in the manual, but does the Nano rotor have a flap/teetering hinge? My little fp heli doesn't, which means the rotor disc can't tilt without tilting the whole model.
