The difference is electric Raptors don't have a clutch, it's not needed.

Any time a nitro guy shows up at our club he gets the boot because it's electric only If you want to fly nitro around here you've gotta get in your car a drive a while to one of the clubs located 'out of town'.

raptor clutch

Ok I give. The original post was and is on a raptor e-series forum and ( I didnt notice) and I was looking for somewhere to vent about my clutch experience. I gotta look into this electric stuff cause Im tired of clutch and engine failures. How long would a say, 30 or 50 size fly on a charge?( I get 25 minutes per tank and 3 flights before I boost my heli battery) and are the batteries and motors expensive compared to gas? How long does it take to charge?

If you take the cost of Nitro and Electric and look as the total cost over about a two year period the cost is about the same depending on low much you fly. After that Electric is cheaper and has a lot less maintenance problems. The price of nitro just keeps going up and the price of electric keeps going down. A Z50A-800 motor (more power than an OS50 Hyper) is only $134.99 and will probably never wear out.

I still have a couple of nitro and the clutches are definitely a problem area. They don’t last long and are a real pain to change. You have to scrape out all the old lining and glue before installing the new one. If you don’t get it perfectly straight it will grab and take a few flights to ware in.

Flight time with electric is totally dependent on the performance that you want. If you are just sport flying and occasional 3D you can get a power system the will fly for 20-25 minutes. There are light weight ECO-8 helicopters that fly for over an hour.

After flying electric helicopters for many years I would say that for reasonable 3D performance you can get 12 minutes. For extreme 3D (a 50 size helicopter with more power than any nitro 90) you only get 5-7 minutes.

raptor clutch

Thanks Ben! I kinda like the sound and smell and tuning of a nitro engine and my failure incidence rate on mechanical is not that bad i guess. Just found a conversion kit for 500$ without batteries at Helihobby. Thats too steep for me. If the motor is only 150$, why is the kit 500$? Thanks again

The reason why the raptor clutch gives up is usually engine misalignment. This causes excessive fatigue in the shoes which ultimately results in fracture; any misalignment that exists will cause the shoes to oscillate up and down as they are taking up the misalignment. This is of particular concern with manouvers like sideways tictocs as the plastic frames flex, but normally you should achieve a good few hundred flights of abuse until the clutch says byebye.

raptor clutch

Thanks Yug. I think you are right but/and I have no way of measuring alignment. I know when I place a clutch in a clutch bell there is too much side-to-side play. Thats why I posted the liner suggestions. The motor mount holes on the Raptor are very tight and the clutch bell/starter shaft are very loose(side to side).So.. Thanks again!! Oh, and my last clutch failure was not the clutch but the very bottom end of the starter shaft wore down and would not grip the one way bearing in the clutch. THANKS!!

I can't imagine that a clutch lining won't last the life of the helicopter if you know what you are doing and don't have hot starts or do the funky chicken with the engine wide open. I rarely do a clutch lining on any of my machines. I replaced 1 clutch on a Rap 50 V1 after 4 years of continuous service but the lining is still the original. I've got 4 gallons through an EVO and I'm still on the same lining and clutch.

Raptor clutch

I had a misunderstanding with TMoore( My misunderstanding). He sometimes posts a "Quote" and replys. I thought his posts were directed at me. I finally understand( damn noobs- example-ME). So thanks all and here is his mail to me. Hope you dont mind professor........... Jim,As you’re finding out, the promise of electrics hasn’t quite gotten us to where we need to be just yet, in spite of the enthusiasm that some of us have for them. I’m like you, when I get out there, ready to fly I want to do it for 10 minutes at a crack. In my back yard I fly a Trex or a Mini Titan and if I hammer it for 4 minutes it’s just about out of gas so I just go put another pack in it and go fly because I can fly it in an area about the size of a postage stamp.

Nothing and I mean nothing compares to a nitro powered machine. In the case of your Raptor, I’ve got to think that there is something causing a major amount of runout in the clutch assembly causing the clutch shoes to break. One tip that I pass along to everyone that flies a machine with a clutch is to take your time spooling up. It doesn’t have to take minutes either just gently push the collective up and give the rotor system time to catch up so that the clutch won’t slip on spool up.

Thanks everyone.

The professor thing is kind of hard to take, I don't deserve it for just making posts or for any other reason. This is Mark's way of charting our participation in the forum.

Take a close look at the clutch assy and make sure everything is as it's supposed to be. There are a lot of good dudes in the Atlanta area that would be happy to help you with your heli in person.

Thanks

Thanks. Just by chance(I didnt know before I started flying) the famous John Benario is in the club I joined and we sometimes fly 3-4 times a week. And the liner tip was his. I never tire of watching him fly the blades off of his Synergy.He has helped me and motivated me alot. And Ed Kinkade with his Synergy and Knight and all the guys.
