Pocket rocket !

My PZ in the long version was airborn today. Rotor now is 45 cm, TOW is 210 Gramm, highspeed tailrotor 1:6,5. Just only 2000 rpm headspeed for lift, this is only 50% motorpower (RCMart BL Motor) at 65% power. than I have a rocket ! Crazy, very crazy! INCREDIBLE !!!

Sub-Micro helis should be light, they fly better that way.
If you watch the this video carefully, look at the black canopy heli, there is no fighting the natural pull of gravity on the helicopter weight, because it is lighter, in comparison to the Pocket zoom, it flies at almost 1/2 the weight. It is not a floater but just the ideal weight, to alow a pilot to fly it confortably without the worry of damage in a mild or hard crash.

The Pocket Zoom even with some of weight reduction mods, still comes out heavy even with a lighter canopy than the original and cutting down as much as possible everywhere on the heli, including using lighter equipment and minimizing lengthy wires and connections. The problem is that there is a lot of mechanical parts, on the Pocket Zoom, necessary for more precise CCPM, but unfortunately, just adds weight. If the electronics were 1/2 the weight of the ones recommended with the Pocket Zoom, then the Pocket Zoom would fly much better.

MIA Micro Flight was challenged with this "ideal" CCPM weight to lift ratios, in their own Sub-Micro Designs, for years, since their first 2001 House FLY Sub-Micro helis. MIA wanted to make one of their HF, full collectice with a similar setup to larger nitro helis , back then, but the weight factor for such plus, electronics and batteries, at this sub-micro scale, at that time, was not favorable. MIA bypassed making a simple mechanics to reduce weight and made a "flybarless" CCPM House Fly. NiMH Batteries were sort of the new thing when MIA made these helis. See pics.




Making a Sub Micro heli with a high degree of precision, that is not a brick to fly, and approaches the precision of larger ones, is still a challenge.

With this in mind, the Blade canopy actually weights a lot more than the original pocket zoom canopy. Not sure If I would want to do use that big heavy canopy on a heli that should look small and cute. If you want to make a heli look like the Blade, but smaller, simply reduce the size proportions of the original blade helicopter.

We all have understand that you don't like the Pocket Zoom, but this heli is very popular at the moment. The Blade CX canopy has accurate the same weight as the original PZ canopy, isn't too heavy. My PZ flies very well, and the long Version has incredible flight performance.

You missed my point. I like the Pocket Zoom! it is just a heavy small heli. Are you certain about canopy weights? Here is what my scale reads.I think the CX canopy is about the same weight as the standard Blade one. Even if it is same weight as the original, compare that with the ones from the Bumble Bee canopy weight and you see why I think the Zoom is a brick and we are just talking canopy weight. The Pocket Zooom is roughly the same Size as the BB.

I think you never had a Blade CX Canopy in your hand, but here I show you:

Even if Blade CX and Original PZ canopies are of the same weight, the overall heavy weight of the PZ still remains unchanged.

Making the helicopter longer will make the heli even heavier but it will improve the dynamics of the rotor if it is enlarged in proportion. However, my point with this was why not just use a Blade CP and shrink it instead of going the other way around. This way you also have more robust parts and you will probabbly end up at about the same weight and possibly cheaper too because a lot of the parts for the CP are easily interchangeble with other similar inexpensive helis like the Honey Bee King for isntance. Of course the motors would have to be replaced with ones sized according to the rotor size. Have fun!

Do these "upgrade frames" become comercial kit?

Yes skywave, it is a conversion kit from micro-heli-tuning.com

@ skywave
Yes, the kit is very expensive, but very useable. Here i have an other airframe for you, made of G 10 with carbon tailboom.

This is made for 20 mm Servos, a very stiff construction.

Can the "one way" gear wheel from GAUI be used in the "pocket MP" frame? The main shaft in this conversion kit seems not the original one, right?

Yes, all other frames need a longer main shaft. One way gear is possible, no prob.

Hey freshair You are the designer of the carbon frame from micro heli tuning?How many grams is actually saved from your frame versus stock with the stock landing gear?Reason for asking is beacsue I think I just made a deal for a 100ep.You know we always got to modifyWhat is needed to convert a stock setup 100ep to your version?Your version on micro heli tuning is the same size and fits the standard canopy right?What gyro is everyone here using on this bird?Which one works the best?

hey Sm1nts2escape,
If you will buy the combo package incl. servos and gyro that is ok. Only the original frame is not stiff enough, and if you want other Servos you get some problems with the original frame. Thats the reason why I made a new airframe, same weight but very stiff and no prob with other servos.
kind regards

have you guys seen the mini zoom from infinity hobby with the all metal components/? Looks nice. Was wondering if everyone is flying these on 2s only or will 3s work. And what pinion would you need for 3s? I see the motor coming with 15t pinion.

Yes robl 45,
I know this frame. The designer must visit my webside many times, but this frame must have more weight and my servo holder gives more comfort.

Hey I have the ep100 pro from infinity or Fling-hobby. The heli is great inside a house on 2s. I have flown it on 3s, but the throttle was turned down to 65% to keep the head speed around the 4300rpm range. What a rocket on 3s!
On 2s, 4800 Gaui motor 15 tooth pinion, 4200 rpm headspeed, the heli is really nice, fun to fly in close quarters, I have mine hovering almost as good as the Trex. \
One thing on the ep100 is the blades. The foam 3d ones have the best ciclic. the flat foam blades have the most lift (like 50 percent more). the wood blades fly well upside down like the 3d foams but with less ciclic responce the wood blades are also quite stable. the fiberglass blades are very stable but with even less ciclic.

For me in the house, I use the foam because I can crash into everything while just breaking foam blades and maybe bending the main shaft. Eventually I want to loop it inside a house, but need more time with the heli to justify.
Outside? 3s and 4400 rpm on the wood or fiberglass is the best, but why bother...get a t-rex. I have done loops outside on the 2s, but need recovery room.
In order for this thing to fly at all, you need at least 4000rpm so get the pro with all the aluminum goodies.
The carbon frame on the ep100 is heavy (about 30 grams more than the ep100 plastic) but it is very very stiff and as far as I can tell won't ever break.
My RTF Pro with 6.6 gram servos and big pcm 146ip receiver is 246 grams.

I don't know how you are doing flips on 2s, I tried that and went head first into the ground. How much pitch are you running?

I can only get 12 degrees of pitch in either direction to be equal. When you flip it, it is not a regular heli that only needs a little bit of stick movement. When it starts it's rotation, you need to pull full negative on the stick. 14degrees of pitch would be way better, but I cannot seem to get that on the inverted side and still have it on the right up side.
When I first set my heli up (14-16 pitch) I did not check the ciclic up and down in all directions. What I mean is that if I pushed the collective up all the way then gave it full forward ciclic, I would not get full ciclic because it was bottoming out the servo throw or something.
So when I went fling and gave it full ciclic to make a correction, the swashplate leveled out and wammo!
