Assuming that the Ino Labs fit, the carbonite gears should take most crashes in such a small heli without stripping. It took a lawn dart that bent the mainshaft 45 degrees and broke the feathering shaft in half (both grips exited the helicopter and had to be searched for in the grass) to strip the HG-D260's and even then it only bent a few teeth on the middle gear. The servo still worked but was gritty feeling.

ok, thanks for the info.
maybe it is possible to split the brushed esc into two parts to save on weight, I would need to study its circuit design to be sure myself, but the same has been done with other brushed double esc's.
The potential weight saving could be worth it for this size heli as you are adding a brushless esc as well, although the extra power from the brushless motor may more than compensate.

@pmerritt - thanks for your offer but I am completely sick of this servo. I have several stripped ones lying around and I don't want to any new ones. I have got a number of Esky servos around that I may try at some stage.

@mono - the servos that are known to have worked in the 4F200 and V200D03 will definitely work in the Master CP.

actually, the stock motor is 89.4 grams and the new motor, brushless converter AND esc come in at 51.8 grams....i'm actually saving weight!!!

I ordered 10 of those hk orange metal servos

I hope they work and are back in stock soon

Hi Tom,
Hows the T-Rex 250 doing? Still fly at that park ? I Need to stop just flying indoors as need room to open some helis up. Every time I decide to fly outside we get thunder storm. Monsoon season is about history as well as hot summer here in good los desert. Cheers,Dan

Not sure if you'd need to do the same for the Master CP, if someone can take a photo of how the servos are mounted, that would help.
The extra weight of the MGs makes no difference as far as I can tell. They are however, quicker than the 7.6.6 servos which is another benefit.
the mastercp doesn't have side frames, i think those servos would be very difficult to fit without some major fabrication. I hope the hitec servos i purchased work ok. They cost about the same amount as stock but they should be much better performers.

But with this 200 sized model spinning much smaller blades and plastic head........This motor is small, weighs little, and gives a decent amount of room for the surrounding wires. The stock pinion fits it and the mounting holes and even the stock screws from the motor fit. I can't wait to get everything going. Still waiting on the batteries to come in!!!! I'll be certain to make a video when I get it all working just don't be surprised to see me babying it early on....hehe. Don't want to break it on my first few outings ya know
I guess HB2622 is 5000kv and if i am not wrong than it will be too much of a head speed (5500+ rpm ) provided you also use 13t stock pinion. Master CP main gear is 115t and i remember dkfuji mentioned in his previous posts about using a 4200kv bl motor with stock pinion that made the heli rocket.

I am using a 3500KV bl motor with 11t pinion in my V400D02 and to me the power is more than enough. Keeping in mind the same it is just my guess that for Master CP any bl motor around 4000kv and stock 13t pinion would give it enough power (head speed of 4200+rpm)

I (like many others) use this excellent eCalc to get the idea

i'm planning on running a 10t pinion. If the headspeed is still too high (which it shouldn't really be) I will just lower the throttle curve to compensate. Again, the reason I went with this motor is the size, weight, and many people said it was a good motor and basically trouble free.

250 is flying better than ever, I'm still being a bit of a wuss with it. Its been a few weeks since I flew at the park due to being out of town and weather but I went down twice this weekend despite the wind. Hopefully the gusty winds will be done soon and there'll be some pleasent flying weather. I wonder if anyone's ever had their heli struck by lightning....

Doubtfull, not many helis are mainly metal, and if theres a tree/tower/radio mast / whatever nearby it will likely strike there instead.

Well if it happens I hope the camera is rolling.
Anyway, it's not a good idea to be out in an open field during a thunderstorm.

Lightning would have more probability of cooking the unfortunate fellow flying the model rather than the model itself, objects (including peple) which are in contact with ground are the highest risk.
But the odds are probably less than winning the lotto.

Very true, no one should tempt fate! Actually I think a heli might be pretty safe since it isn't grounded.

Like someone mentioned, the dude with the metal antenna would likely be the better target!

Hi firewolf, do you think this 3900kv Hobbymate motor will work on master cp?

http://www.ebay.com/itm/Hobbymate-HB...item2574ed12c2

And a brushless esc will be a necessary with the motor right? How to configure the esc connection on rx, which channel shall the esc goes in? And what how to connect the stock brushed esc, which originally control both main motor and tail

Thanks
