Have to agree here as well. I was three months crashing and rebuilding my first CP heli on a weekly basis, before I could achieve a loose hover like Rafa just demonstrated. Perhaps the 4F200 may be a good transition to CP heli suggestion if it holds up well over the next few months. Looks good so far anyhow.

Im hoping to see my 4F200 delivered some time this week.

Nice flying Rafa

How does it compare stability wise to the 4G6S? I am searching for that yet to be developed "indoor CP".

What do you guys think? very neat inside, must be well planned before cutting fuse....will get some brush paint in white/blue/red soon.

I am wondering the same thing. Maybe walkera will come up with their own version of the Blade SR cp.

Take III. More newbie questions.


Hi Guys,

I went for my third session this morning (no video this time), and now I'm thru this battery break-in thing that the manual talks about (With the battery fully charged, let the battery discharge to no less than 70% charge, then charge fully again. The book says that doing this 3-5 times will increase battery like and consistency. I did it 5 times.).

Anyway, I figured that if I could, I would stay in the air as long as I could, to try to gauge how long the battery lasts on this thing. The good news is that I made it 6:48 with no 'ground touches'. At 6:49, something went wrong. Maybe I goofed, maybe the battery went flat, I don't know. All the sudden, the heli stands on end, then comes down to the ground, doing a little cartwheel on the training gear. When I got to the heli, all was fine, with the exception of the tail pitch slider assemblies and tail blades. One of the blades broke, another one of the blade holders got torn from the hub, etc. There begins the $ and downtime that everyone was talking about. I knew it was coming at some point, I was just hoping it would happen when parts were more readily available. I can't complain, it was a great 6:48 (all tail-in)! I even flipped into ST-1 for a second or so in the middle of the flight, just to see what would happen. I got scared as I heard the motor spool up so I flipped the switch back to normal--that's what happened.

Oh yeah, my question. My CB100 would just slowly start to lose power as the battery discharged, and I knew to bring her down when the heli wouldn't 'punch' anymore. Should I expect a similar thing on this heli, or will it suddenly just give up the ghost?

So, I probably shouldn't ask but does the Walkera use a standard 3mm main shaft?

I am afraid not. It is a 4mm shaft. Also, the pitch of the main gear is .25mod and so is the belt drive gear. So, that makes it difficult to change things out or use a standard one-way bearing set-up. There are rumors that Walkera is working on fuse's for this heli as well.

The nature of the 3 axis gyro is it will go nuts when the voltage drops. There is no telling what the heli will do if you fly out the pack. One thing I do know is the stabilization ability goes haywire when the battery pack is flown out. This differs greatly from the CB100.

Thanks. Knowing this makes me feel better, actually.

There it is, we now have a baseline as to the absolute limit of time a stock battery can just hover around--6:48.

It so happens I have one of these fuses laying around. Did you relocate the battery or are you removing the front of the fuse every time you access the battery? How'd you cut it so clean? And what holds it firm to the guts?
Let us know how it flies with the full fuse on. I've been holding off on this heli, waiting for the larger Esky version (CT), but if the orange 222 fuse works good, I might forget about the CT.

I want to keep everything as stock, changing batt will need to pull out the first haft (thinking of using some small magnet to keep it fast-snap).After trimming fuse weights about 92g, heli still lift up with plenty of power! I use a thin scissor with small tip to cut the fuse and finish with some sand paper.You onle need to find some best place on chassis to put some tiny screws for holding the tail haft-fuse ,the front one once snap in will fit tightly between landing skid and battery holder, so just need to make it "married" closely with the other half.Anyway, there is some stock screws that fit perfectly with the fuse if you wants to keep it tighter but i think that's not very important tho.
Putting a 3blades heli on scale really change a lot of look. Hope i can finish it nicely!

Nice work A. It is going to look very cool when completed. All you will need is some lights next. LOL.

He he. . Of course. I actually installed the 180Q fuse on a 3D EP200 a while back and it did look very cool. Here is a vid of it flying in the park. The added weight did effect it flight characteristics though. The tail was not as snappy but of course I had some really cheap electronics in it and it was not flybarless. I also replaced the landing skids and built an aluminum subframe for the landing wheels to keep the "look".

ok, some update.It's really a pain for removing tail rotor, belt drive assembly to put fuse in so i've cut-off a 5mm space along the tailboom-fuse to make the job easier.Just snapit in and keep it tight with the existing stock canopy holder pin. This way, it will be verey simple to take it out for maintenance.Don't worry, plastic fuse can be slightly bent without breaking. So far, i'm looking for some magnet for the other half, maybe finding on some glasses clips....Also, using a thinner batt will give more space on the upper end & made fuselage fit more nicely onto the front.
