i stable my heli in 1 speed in the air without moving the throttle stick
then it suddently drop, then climb back

why is this happen? i crash again because of this, it happened when i hover, but i just ignore it
when i fly it around, it like this again, so i crash again

no damage i can see, but the wobbling is now more obvious, and tail boom is bent,
i suspect the blade shaft is bent, or mainshaft bent
or both which cause the wobbling

for the tail boom, i just straighten it back

why my heli suddently lost power then comes back to normal?
esc?

I have the same problem too, so far when I clean up the motor's connector then the problem gone. Might be my ESC too but now OK already after cleaning the connector.
You'll need to verify and check if you have the same problem like mine.


Added on November 7, 2010, 6:40 pmMaiden my Cessna, thumb's up for this trainer plane for beginner.

At first when I poke my finger at the CG to check the balancing and found the head is heavy a bit. Put some weight at the tail to balance up but then very hard to fly down. Then just dun care and remove the extra weight, it flown better and much more easier.

Hehehehe, anyhow I crashed 3 times during landing because the grass is thick on the field. But surprisingly there is nothing serious and only the nose wheel is bend. Repaired and it is ready for another flight next round ..... it is really relax to fly than a heli and I can easily fly further to 150 meters away. Love this plane but too bad I have no maiden video ....

Quite fun and scare because I was flying in a big soccer field around my house in hometown. There are a lot of terrace houses and sometime my plane just on their roof .... hehehhehehehe, although it is very high but if lost control then it is very dangerous ......

Aiya, why some Malaysian so bad one. I want to order some parts from US to mod my nose gear but guess what, they stop entertaining us because there is a large increase in fraud from us.

How to fly? People stops selling us their parts tongue.gif .... hehehhehehehhe

But I just received my Cessna parts after 3 weeks, the stock prop so cheap in price but came with the adapter too ... initially I thought just only the prop but now so happy that I don't worry about bending my adapter already as long as the motor shaft is true.

Hehehehe since I have 2 spare props I think I don't plan to do this at the moment but I would rather to mod my nose gear.

The crash during landing in the past was all because of the small wheel I have with my Cessna I think. It has wheel pant too so landing on a field with thicker grass is almost impossible. Think of changing to a stronger nose gear with bigger wheels. If I have to change the rear wheel too then I am considering to remove the wheel pant but no longer that scale looking loh ..... what wheel size do you think it will love the grass?

California ... just tried to find out the shipping $$, it is slightly more than the price of the parts I am going to order ...... too bad .....

DIY also can lah but this time need to replace the whole nose gear, a lot of effort to find DIY materials loh ......

Ya, talking about epoxy, is that every type of epoxy applicable on EPO foam?
What's the differences in using foam safe CA and epoxy? I have heard that foam safe CA will make the foam brittle .......

Yeap, this is the one. funjet is faster ar? hehehehhehe, let me check it out ....

And then for epoxy ah, those that selling in supermarket or hypermarket can use on foamie plane or not? Instead of the epoxy you shown me in hobbyking which I need to wait for weeks to deliver.

I think i dont need epoxy for my foamie now, I want to get epoxy to install the nose gear upgrade on the firewall. The firewall is made of nylon.

But of course, I do hope that I can reuse the epoxy for my cessna repair in the future. Anyhow, touch wood first !!!!!!!!

motor mounting is something like aluminium then mounted on a piece of nylon for my cessna. Then this nylon is stuff inside the foam. Something like this ....

Start from 1:05 minute


Added on November 13, 2010, 10:27 pmIf I can only choose for either 30min or 5min epoxy for foamie, which one is the best?

Walkera's micro heli can actually allows you to do a lot of DIY job for part replacement if imagination is good enough tongue.gif
Just a bit worry that we will bring this habit to a bigger size heli later .... hehhehehe, I used to bend the 4G6 main shaft back after some crashes and reuse. Recently I did the same thing for my BCP main shaft ... wahahhahahah

I am a slow flyer. Not flying my heli slow but I mean I am slow in learning. Use to fly during weekend only so after 6 months then only I started to fly more nicely in F8.
Until now I am still doing nose in hovering with my BCP and 4G6. It has been 9 months since my first coaxial until now.
