EXI 450 Pro Shaft

       Remove this ad - become a site supporter!
I have just upgraded from a 3 ch indoor and a 4 ch Walkera Dragonfly 22D, which I find impossible to control it seems to be out of balance or something I got it used, to the EXI carbon 450 pro shaft. I have not flown it yet I am still waiting on some parts. Well my question is should I start with something else before I destroy my 450? Or should I be ok as long as I leave on the training wheels lol.

Re: EXI 450 Pro Shaft

I posted on your other thread, so have a read there too.

The 450 is actually a good CCPM heli to learn on and as I mentioned in your other thread spares are readily available. It is a lot more stable than smaller machines, (I started out with 3 King 2's, very soon making them into "Baby 450's" and compared the original machines to an "Epileptic on Red Bull").

However, no Collective Pitch heli will fly anywhere near like a coax machine. These helis have no inherent stability and any input you make to any control system affects all the others. Just like when I learned to fly real ones, it was comparible to dancing atop a greased beachball while twirling a plate above you on a stick. A good training reference is Radds School of Heli Flying, available for download.

Training gear is good, but if installed incorrectly can actually contribute to problems. Most times I see it connected directly to the skid tubes. The issue is that now the balls support some of the weight of the machine. When lighter on the skids during take off or touch down that can start the heli oscillating. The best method is to fasten the sticks approx halfway up the legs, (rubber bands are about the only thing that will hold to the tapered legs and not drop). That way the training gear will only come into play when really needed. I found as I got better and more confident I shortened the sticks in progressive steps. Once I was down to near 1/2 their original length it was time for going without them. I think this reduces the major difference when first trying it "Commando".

One other thing about training gear is that the gear itself can and will contribute to oscillations as the mass of the balls on the ends of the springy C/F rods will vibrate. The heli will also be a bit sluggish on cyclic with that mass out there, as well.

You will also want to try starting on a hard surface. Carpeting and grass do not allow the heli to slide if you have any horizontal movement when taking off or landing and will help the heli try and roll over.

Finally, due to ground effect you want to try and hover at least 3-4' off the ground. The heli will actually fly better when not interracting with its own rotor wash and it gives you a bit more time to correct for minor mistakes.

If this is your first CCPM heli I would advise you to look for local help. They can give you a lot of advice and check out the machine.
I know there's money in aviation........I put it there!

Re: EXI 450 Pro Shaft

Thank you for your advice on both topics. Unfortunately I do not have much local help here in Japan. The biggest problem is I don't know any Japanese yet lol.

Re: EXI 450 Pro Shaft

I started with Realflight and although some guys don't suggest you do, I do. I spent four months learning to hover before I would consider the real thing and It helped. Back then Realflight G2 was all you could get. Now with Realflight G5.5 and Realflight Basic you are far better off than 5-7 years ago. Trade someone who wants to learn English for helicopter lessons and that pro should be flying in no time! Kidding aside, The pro is a good helicopter and with help there is little comparison between the collective helicopters and the co-axial or even fixed pitch heli's.
