Wasp Auto CP RTF 7Ch RC Helicopter With One Key Auto Inversion

Product Review (submitted on 28 November 2014):

Top notch on all degrees. It's small, it's light, its battery lasts quite a long time, it flies well in 3D and can survive a nasty crash with a bit of easy repair.

Strength: Extremely strong. Frame will give way (crack) and literally pop out parts that are under extreme stresses. Example: the tail boom holder cracked and let the tail boom free so the tail was fine and wasn't snapped or damaged. Pop it back in place and it's perfectly fine to fly again. To remove the crack, just use a dab of super glue.

Agility: I'm new to 6ch helicopters and it's definitely a step up from 4ch and quads. The power is UNREAL. It's also got very good receiver distance and the gyro keeps everything nice and steady against wind. Going from 6 axis gyro to 3 axis did throw me off a bit though.

3D capability: This chopper (believe it or not) is **VERY** capable of 3D. Just dive into the transmitter's settings, increase the D/R (dual rate) to 75%+ and it'll have no problem flipping over. You may want to customise your pitch curve though because the negative pitch was quite shallow for stock. For some reason, my model didn't come with that "auto inversion switch" and I'm glad it didn't! Learning the proper way is always better.

Battery charge: The chopper comes with a USB wall plug to use with a usb charger, and that can supply quite a bit of current. If you use a 1 to 5 way splitter, you can simultaneously charge 5 batteries at once! But it'll obviously take longer and the battery's must all be flat. The chopper can last around 10 minutes in normal mode (with the right set up) and around 5 in idle-up. Not bad for 240mAh.

Faults: There are 2 faults with this but I think they can easily be solved.

Issue One: the servos are unbelievably delicate. I've already stripped my front servo and I need to get it replaced. £10 for a single servo is quite steep, but I don't think there are metal gear 2g servos around. It's also irritating that these servos are 5pin instead of the regular 3 pin.

Issue Two: I'm not sure what's causing this, but if you hold your cyclic in any direction, the servos don't move there quickly. They move around 3/4 the way fast, then go really slowly for the other 1/4. Letting go of the cylic also warrants the same problem. This can cause issues while flying because the response time is massively reduced.

Overall: The 2 faults are nothing compared to how great this chopper really is. I love it to bits! Quite literally, I've already broke a pair of blades and the tail boom holder haha.

Definitely recommend for intermediate-advanced pilots. Not for the faint hearted that are just starting out because it'd be too responsive. Anyone who has experience on quads or 4ch helicopters (single rotor) should be able to jump straight onto this chopepr, but I'd recommend a slightly bigger one because of how squirrelly the smaller ones are. For the rest of you, I suggest you download a simulator and practice! Aerofly RC7 does a good job, so I recommend that.

One thing though.. It has dual rates, but no dual rates switch or knob.. But there are knob/switches on the side that do nothing on the transmitter. What's that about? Can it be used for your rates? Who know.

Happy flying!
