Sand is a very soft landing...doesn't take much to stay together jumping in sand.... The Mugen is many times over more durable then the Hellfire is...you would be much better off to buy a Mugen ! its honestly not even a fair comparison... The Hellfire's may be decent enough to plink around in your yard, which is why I say unless the price is dirt cheap, and I mean dirt cheap ! do not buy it..... Even if you paid more for the Mugen initially you would end up saving money over the long run as the Mugen is going to break much less........ So its up to you, if you love wrenching and fixxing buy the HPI, if you prefer to run all day instead buy the Mugen...... Also to consider is the Mugen is an awesome performing machine, the Hellfire is not anywhere near as capable as the Mugen.... So not only will the Mugen outbash and outlast the HPI it will also runs circles around it in any form of performance comparison ...truly we are comparing two different classes of machine here.........
