What Tony said is consistent with what my vendor said as well. But it really depends on what you are comparing it with. He is not a micro heli flier and so I would not take his comments with a pinch of salt. He also said that the material looked cheap and was surprised that it was being sold for more than $80. He is used to flying high end stuff as Logos, Henseleit, Kasama, and Trex 600/700 owned by this clients. He is a video of him flying a Logo 400 that belongs to the owner of Helipal. Just look at the power of thing, especially those 3 consecutive loops at the beginning.

I'm still confident that if you let the motor cool down in between flights it should be ok. Lot of problems with brushed motors appear when people do several flights without pausing in between. But time will tell. What I said before. I never had brushed motors suddenly stop in flight. I notice a degration in power long before the motor dies. And if I notice this I replace the motors.

The problems of the V400D02 are well known and that ls why we have to take V999D02's comments seriously if the same motor is used. I have used the same 7-6-6 servos in other helis and they are pretty bad as well. The V400D02 is a cult heli which has a large and loyal following despite its problems.

The V400D02 never sold well in Hong Kong. Vendors usually did not carry spares because they were usually bought by tourists. For some reason, the Master CP is really selling well in China now. I wonder whether it is because Walkera is perceived to have improved its quality since the Genius CP.

+1 on that.

I am really at boiling point right now. I got 4 batteries and found that the heli would not work when I plug it in. I am sure it is the ESC as I was able to power the receiver using a BEC for my 250. I suspect the ESC was damaged when I tried to plug in the battery with the erroneous banana connector.

The battery was a third party battery and so it has nothing to do with Walkera. I am just mad of all the helis that have been sold by my vendor, why must I be the only one with this dud battery? If you buy third party batteries, make sure you check everything is alright with the connector before you plug it in.

Pfff, that's a case of real bad luck. Can you get a new ESC fast?

I would think so, I don't really think this is my fault.

I see you are in Hong Kong. Should have an ESC soon. In my case I would be grounded for 1-2 weeks.

I have about 20 flights on the stock brushed motor and it seems to have the same climbout power as it did when it was new. I do not fly a brushed motor back to back so I give it ample time to cool down. So far, it has shown to be reasonably durable since the last crash was full speed reverse inverted flight into the side of my house. Damage was a bent tail boom, fractured boom support connector, bent vert fin, cracked horiz fin and a stripped elevator servo. All shafts were still straight, blades survived and skids had a serious paint scuff mark but still in one piece. Not bad really given how bad the crash was. I bent the boom back, epoxied the support and fins and replaced the gear in the servo and the heli is flying just as it did prior to the crash.

I have also installed a BL motor conversion. This heli becomes a rocket using the TA 4200 kv 3s motor on stock pinion and 18A Gaui ESC. IMO, it is no longer a beginner's CP with the conversion. Its just too quick and a the flip/roll rates are aggressive to say the least. Anyway, the tail holds solid even with full pitch climbouts inverted or not. Pretty good for a brushed tail motor set-up.

IMO, I would rather keep this particular heli stock brushed for some relaxing mild 3D flight. Just my personal taste is all.

Actually, its kinda Walkeras fault, as they have decided to have their connectors reversed compared to whats usually used with those connectors. Its the same on the mini/gcp.

Any chance of letting Manuel have a go ?

It is very difficult to describe what happened, but it was not a simple case of reverse polarity. The factory just got it wrong with the connector. Walkera has been using the mini/gcp connectors for years. Since they are probably the largest user of these connectors. they have the right to dictate what is usual or not. It is the others such as NE who are not conforming.

I ordered a couple of more helis so I would have spares available before he takes a shot at her. I figure they should be here this week so that would open the door to some Manny test flights. This heli has no idea what she's in for then. LOL.
