Windchill outide -10  :134:

I like it very much. And I think that I did not like it when I started learning.
Piro speed is insane, even clockwise.
The tail seems to hold better in the dutch windy conditions too.

Maybe tonight I go fly indoor and will test it in FF and FFF and curves and stuff.

Love the sound too.

The motor was 1 buck more expensive then the Bee V2 stock motor.

!!! Needs a new heatsink, a round one. Just forgot to order. Now heaving 2 Bee heats which do not work that well on the new motor !!!

Very happy with it  :130:

I gues I have t make a small vid for you ?!

HBFP NL: you better put the heatsink the other around. It's much better, more aerodynamic. You might need to desolder the cable first before putting the heatsink.
In FF, this heatsink works alright.

I ordered a new heatsink, I will wait till that one arrives and put it on a different way.

I gues you mean the same side, only heatsink upside down?

No. Right now you attach the heatsink from the back of the heli or in your picture, on the left side of the motor. You should attach from the front or right side of the motor. So the fin pointing towards the back.
With your setup, the fin kind of blocking the air. If you put it the other way around, the air will follow the contour of the heatsink fin.

Hi HBFP looks great I think I'll order one tonight.  :127: If you want to fly you can make a heat sink out of some heavy soldier (like they use to soldier pipes) wrap it around the motor and it will dissipate the heat.  :138: vsbkv  :oldcane: :flyaway: :propeller:

That looks like an possible upgrade for a DD tail.  Did you look at the "super" motor?

Looks good  :138: how is it in terms of tail weight compared with the stock setup ?

Thanks for the information. I have 1 question left. By blocking the air I thought I had a more effecient cooling? What is your idea about that?

Good tip and I will reveive a new heatsink today!

It's just my opinion with not blocking the air, because it will cause some drag.
This is what I use now






If you want to fly you can make a heat sink out of some heavy soldier (like they use to soldier pipes) wrap it around the motor and it will dissipate the heat.
The stock Esky heat sink weight like nothing. Very very light.

What super motor you mean?
You can use HBCP3 tail motor.

Hello Penguin,

I am looking at the Xheli page that list the spare parts for the CP HB and they show the main motor as "370super motor", part number EK-002393.  I was wondering if it would have a positive impact?

I may place an order just to find out.

Stock motor 8.2gr
CP3 motor 15.2gr

Stock prop complete 5.2gr
CP3 prop complete 1.8gr

Stock tailfin incl bearings 5.6gr
Modded stock fin ex bearings 4.4gr ( I modded the old shaftholder away and also dremelled the nasty point from the fin bottom).

Stock HBFP V2 heat sink 0.7gr
Stock CP3 heat sink 1.8gr

So here we go:
Stock setup for tail: 19.7 grams
CP3 DD setup for tail 23.2 grams

Cheers for that HBFP  :136: I had a feeling the CP3 tail motor would be a tad heavier however all up that only equals an extra 3.5g of tail weight, which should be able to balance out with repositioning the battery a little if it matters.
