what's the diameter of the main motor on the HB in mm?

Looks to be 24mm (15/16 in).

And you won't go much bigger. The front servo's arm barely clears the motor can. This rules out the speed 400, and I think it rules out the 380.

If you're considering brushless, it's been done by "pulling" the throttle signal out of the 4-in-1. But, the person that was brave enough to try it had problems with flight times. Here's the thread: Esky Brushless How To

batfalcon,
My HB2 doesn't cut off at 9 volts, the li-poly's I have will not lift the heli at 9 volts. I did drain one battery pack to below 9 volts by "dancing" the heli around on the floor. The battery survived, but I won't do it again.

batfalcon,

With the timing advanced properly on my 370 motor i could easily keep the honey bee in the air when it reached 9 volts ( of course you could feel it was losing power) anyways thats why i bought the warning led that i mounted on the 4in 1 box. So i would know exactly when to stop flying it.

To all,

Well since the financial department gave the "green light", I went to the store and brought home a "Twister CP" yesterday evening. After the charging was complete I gave it a try in my living room. It was the 2nd attempt. The first was in the hobby shop where everything went smoothly.
Don't exactly know what the h... happend but both the main blades are good for the fire place

. I hadn't flew it for more than 1 minute. This machine is MORE sensitive BY FAR in stick movements than the FP. Today the hobby shop will get 30 more €.

I am thinking to move the push rods of the servos 2 holes towards the servo. Not the pitch servo just the other 2. That's what I did on my FP to reduce my over-reacting.
Fact is from what I saw that the CP flies less smoothly than the FP. It responds to the corrections more rapidly than the FP, giving you a feeling of insecurity.
What do you think ?

paedbo,
Did you retime the stock 370? How? I've been thinking about straightening the four crimps holding the brush plate and turning the plate a little to advance the timing. Is my thinking correct?

batfalcon,
If the Twister is just like the HB2, all three servos are used for both pitch (collective) and cyclic movements. For collective, all three servos pull the swashplate down. For left/right cyclic, the rear two tilt the swashplate. For foreward/backward cyclic, all three are used to tilt the swashplate. Lessening the movement of any one of the three will throw everything off.

yes i uncrimped them just alittle bit, just enough so i could turn the endbell withalittle force it does not turn freely but its loose enough if you give it a tug it will move, and i used an amp meter to set up the timing , except i went just a hair higher on current draw to make sure it had some more gusto.

Here's my no-yo yo fix for the HB2, if your heli is still new you may not have experienced this problem yet... It started out as a carbon fiber project but while I was waiting for some epoxy to set up I tried aluminum. I have only hand tools, it's tough working with such small parts when your cnc machine is a hand file. I saw something similar posted at rcgroups, and it's designed a bit after the MS hornet. It looks pretty overkill, but I've had the chance to test it a bit and so far it's working great.

Hi guys, im totaly new to rc helis. I think the help you guys give to the beginners is really cool

There is just one favour I would like to ask.....Could anyone pls email some clips and photos of your birds in action.

It would be greatly appreciated.

PS: It does'nt have to be the best flight or accrobatics, it can be anything from take-off to 3d flight.

Not being a HB2 guru yet, what exactly is a yo yo movement that the heli does ?
Plus since I broke my first main blades on the "Twister CP" and a new pair costs 30 €, Ι tried to make a pair on my own. I did not pass the test, so I ask you guys:
1. Do you build your own blades, or you purchase a new pair each time you have to?
2. If you buy them from somewhere, where is that? Any suggestions?

Michael

Yo-Yoing is an annoying & relatively uncontrollable up & down movement of the heli when hovering, anywhere from a few inches to a few feet at a time..some people have reported it happening with the HB2 and have tried many different things (greasing & sanding the pitch slider etc) with mixed results.

Do a search on RCgroups.com under Esky threads to see some examples of peoples fixes. There are also threads on how to make your own blades, if you are so interested.

I generally buy my spare parts fron deeteeenterprises.com, but I dont know if there is a better supplier for you since you arent in the US.

Darrell,

I noticed you said that it might be difficult to find a Lipo charger for less than $80, you might try this link:

http://www.his-hershobbies.com/page/page/1027622.htm

I ordered the Apache 1215 from them a couple of days ago for $24.95, but it's only good for 1-2 two cells and 80 ma to 1200 ma.

I'll order the Apache 2500 for $49.95 which will handle 1-4 cells with selectable rates from 250 ma to 2500 ma when I get a CP heli and change over to the 11.1 volt lipos,

From what I've read about these chargers, they have a pretty high customer satisfaction rate.

Rick

wayne8louw,
go here: http://www.helihobby.com/html/rc_helicopters_videos.html

It has regular videos, 3d flight, full size helis and more cool videos.
When I had my jabo, I used regular plastic blades and I crashed quite a bit. They never even cracked. You might wanna try them out.

loserbaby,
interesting little project. How long did it take you to do that? How did you mount it on there, just put it right on?
Can you post pics of your main and tail motor heatsinks?

Should receive my HB tomorrow!

Batfalcon: You can usually repair blades quite a bit before trashing them. Usually a squeze of CA and some packing tape does the trick. The secret is to re-balance accurately after fixing. It is amazing how much repair a heli will take and still fly! Beats being grounded and waiting on delivery.
Based on my Twister experience, Loserbaby's mod will be mandatory sooner or later. The "no yo-yo" honeymoon won't last forever...

I usually do, but this was my first min of flight with my new CP.

The blades just touched the very same spot where my previous FP had crashed 1000 times, (with no blade damage at all)

, and one of them broke in more than 10 little pieces

. All the damage was at the outer 1/3 in length and at the trailing edge side !!! I was so disapointed that it took me 1 day to lay my hands on the machine. Next day I tried to hover it at the same spot where I had the crash, my stomach was tied

(if I use the correct expresion) and my heart's pulses were near 150

. Didn't have the control I usually have with my FP but I managed to keep it in the air for a minute or two. Have to say here, that the free space in my living room is 1.5*2 m. Furniture all around

.

So for the moment I plan to keep practicing
