The JR digital minis will work great on the heli, good choice.

I may end up putting HS-225s on mine as that is what I have lying around and they are pretty fast.

Good luck!

Jim!

Adapter

Helimike:

If you don't mind spending a little, JR makes a part #JRP960633.

Use this link

http://horizon.hobbyshopnow.com/pro...?prod=JRP960633

$13.25 for 4 of them.

If you want to use Micros like the HS-85s then you would have to come up with something else. I don't think the HS-85s would be a good idea on this heli so I am going for minis. They are typically only about .1-2 oz heavier than micros anyway, and much more robust.

Jim!

ds 8417 2.03 oz. full size alloy gear.
ds 3421 1.04 oz. Mini size alloy gear.

Those plates are not an ounce each.
3 ounces is alot when you are working with small stuff.
Answer your question.

Adapter plates

Actually the adapter plates are pretty light. I used them with my JR Voyager E and they are just about as light as wood, or even thick carbon.

They seemed to work ok for that application. The Quickie is basically the same size as the Voyager E, so they SHOULD work well for it too.

As far as weight savings.

If you consider 5 servos on the heli:

If I use all standard servos which generally weigh around 1.6 oz., my total servo weight would come out to 8 oz. If I went with minis on the collective and a HS-81MG on throttle and tail rotor, the total weight would come out to 4 oz. That's a savings of 4 oz! now, on electrics, this is really critical, but not so much on glow.

Actually, the heli might fly a little better on the heavy side than say my Voyager did. I figure that if it flys as good as my Voyager did, I will be very happy!

Well I just realized they had there head up there ass when they desinged the gas tank. (Look at it closely up to the light and try to
move the clunk around.) To long of a line and it just gets stuck where it wants. To short and you wil flame out inverted or knife edge even with a header, headers are only for bubbles.
The clunk position is all wrong, it cannot be made uesable for 3d
I am looking for a nalgen tank to fit like my fury, I also want to
unscrew the cap and fill her up like my fury with the drinking problem.
I hate fuel pumps.

If I go glow with mine, I will end up cutting the frame out for a regular tank. I don't know why they put the tank in that they did, but it is easy enough to change.

Ok here are some more pics

The way the gas tank lines need to be modified. The lines supplied
are stainless steel and not bendable. So I drilled it out a tad and added
brass lines so I could bend them into a usable position.

The tail blade clearance with 470 blades.

Stock blades held up to the MS 470's

Hotbodies .18

Its only at 160 deg right now and flying a little sluggish.
I am going to take it to 180 190 today and see how it does.
I also just picked up some 40% for it.
