Kind of reminds me of straping on an electric chair

Also great deal on this one for 23,000.

Stock Mini 500 = Deathtrap.

Dump the rotax engine, put a small turbine in it and you have a halfway decent machine, with a few other mods...

That helicopter was WAY underpowered. It was setup to squeeze every last ounce of power out of that little rotax engine. Neat machine but was in need of some changes to be really a decent, safe helicopter.

Just my thoughts on a machine that has taken at least one person I personally knew from us.

This biggest problem with the helicopter is the power plant. Most manufacturers put an engine in that gives them the power they need at approximately 70-80% of what the engine can actually put out. This is what is known as de-rating an engine or powerplant. It generally extends the life of the engine and typically increases the reliabilty of it as well. The problem with the rotax engine is a) its not all that reliable in the first place and b) the engine is just simply too small for that application. Instead of an engine that puts out enough power for this helicopter at 80%, they put in an engine thats working its guts out putting out max power just to get the helicopter off the ground. Not wise engineering. The engine is constantly working at max power, straining every part and component at its design limits and it leaves absolutely no room for error. On a hot day, say 90 or more, a 180 pound pilot would be lucky to get 10 feet off the ground with it. There were some other design issues as well concerning part of the drive train and the control system, but the biggest issue was the engine. There was an individual who put together a package comprised of a number of upgrades to the control system, two different upgraded rotor heads (one being a 5 blade system) and a turbine powerplant. He wanted to sell it as a conversion kit, however thanks to a lil blurb in the contract every buyer had to sign from the factory, he was sued for breach of contract and subsequently lost in court. The factory sued him and won, defeating an individual who could have turned that helicopter around (in my opinion). Apparently the contract states that you cannot make any changes to the control system, structure, or the powerplant on the helicopter. I didnt think that was possible since its an experimental aircraft, but I guess I was wrong.

It has the potential to be a good helicopter with the right changes, but the company is no longer around (that I know of) and not many people want anything to do with them anymore. If you want them, you can find them, but you might be on your own...

Just my thoughts... FYI, one of our most experienced pilots (pushing 27,000 hours total time) was killed as a result of a crash in one of these machines. Rear cylinder in the rotax siezed shortly after take off. Had he been in a Jetranger, he would have been ok, but the low interia rotor system on the 500 didnt leave him with much at the bottom... balled it up, put him in a coma from which he died a week later. Anyway, like I said, my thoughts on the machine...

Eric

P.S. No, that isnt a typo on his total time, ex-vietnam pilot with many many hours of helicopter time

I must first qualify my statement in that I am neither an expert or an actual pilot. That being said, I have been researching aircraft for about two years now for a near-future purchase. Every decent experimental aircraft that I have seen has a motor that is derated for aircraft. application. It is just like your rc helis. We all fly our motors derated except for people who want burn something up. The BH Hanson modified 260 is said to be rated at 4.8 hp. That is in a boat at 17,000 rpm with a tuned pipe. In a helicopter you are only using maybe 3hp.

Low interia rotor systems are the nature of the beast when it comes to weight/power/lift equations. Look at the R22, lots of heli places train with them in the US. They are more prevelant in other places like Canada.
PS it is rumored that Robinson is coming out with a turbine R66.
Life has risks, weigh them and plan your moves.

R66 would be cool...

Canadian Helicopter (largest helicopter operator / school in canada) trains with the R22. But most of the smaller schools uses the S300.
