The VMX is not out yet so no way to compare.

If you compare it to brand bike like Duratrax DX450 , What is the difference?
I interested in a new bike & I hesitate between a good brand bike to the cheap HobbyKing.
What is your opinion ?

Hmm buy them all and let us know. Duratrax/M5=1/5th .ARX,QRF400 = 1/4th. Little info on QRF400 to date from owners due to how recent it is, but from whats posted seems decent for the $. Have to wait and see what venom offers with its 1/4th. Only established bike is the ARX all others are new to the scene.From what little has been posted of the QRF400 seems quite viable for a base rtr /given its start up cost.Too early to make comparos.Only 2 going through the tests with strong RnD input atm is the 1/5ths from what I have read.Another fact is the QRF400 is an exact rip off of the ARX design using cheeper materials.So you can get hop ups and replacement parts that will work from the original designer ARmodelling

This product is not worth the money.
I contacted Hobbyking support to ask them about spare parts.
They told me that they are not going to sale spare parts.
Here is their answer :"We only order spare parts for customer when his purchased product under guarantee".

In this case, This procduct is not worth 1 $ & I am going to wait to the Venom vmx 450

The video shows this bike to be not very stable, but the price is right if your going to run it in a park or schoolyard.I personally am very unhappy with the quality of the dx 450. I think im going to keep my Ricky bike and upgrade it, wonder if any of the parrts of this hobby king bike would work on the ricky or dx 450 , alot cheaper to use as a parts bike

it suffers from the same instability issues as the ARX... when the rear-end slips, the bike tries to compensate up front, and you get those crazy wobbles... when the traction is high, the ARX performs brilliantly... so i can only assume that this bike will be the same...

Hey akura I got my E gyro fixed, It was making the same sounds as yours was. It was the wheel bearings being shot. If the motor rubs at all it will stop and squeal. If you have 3s lipo you can try that and if it wourks it's the Bearings. Because the 3s will overcome the screwed up Bearings. Try that out.

Have you had the Bike at a 1/8th buggy track to see how it goes around that. Thats what I'm trying to do. I want this ARX not to just do good on a mostly flat surface but on a U.S. 1/8th type track. Hey I posted the above and then saw your video. It's awesome. But man get going in the dirt. I say that because on road of anykind is dead and buried out here in Wa State.
