Hey, we've done the 'anyone got the MP' one to death, but who's been up in the air with one?

I'm waiting for batteries now and as soon as they appear it'll be in the air (weather/light permitting). Hopefully before Christmas??

Let's see some aerial shots

Thats so got to be the worst thing ever ... using the MP as an ornament

Might have a 9v batt kicking around it you need it

Hi Richard
Just waiting on a tail servo and it should be up .. I decided fettling up a boom mounted servo was too much hassle after seeing "that" indoor vid.

Is anyone running a non standard (non volz) tail servo?

3DPP Looks good, so how do you like it,
What motor combo are you using?

Can someone tell me what size of tail blade the 3DMP is using?

Thanks
David

I´m using the Kontronic set, Tango-Jazz and 10sp5.
It´s a nice bird good for beginner and also very well for experts, very fast with high rpm, good to see in the air and a real plug and play helicopter, I like him very much and would buy him again.
Congratulations to Jan, I flew everyone of his birds but this one I like at most.

My 3dmp is nearing completion - it is a stunning set of bits and the end result is even better than the sum of the parts would suggest.

I do have two queries though - what Rx pack are you using (800mah seems very small for 4 digi servos & gyro ect?)

The motor pinion, it states in the instructions, needs shortening. I can shroten it but am hesitant to as its quite an expensive unit! Has anyone cut theres down to 16.5mm?

Apart from that, bring on the packs.

Nick T

3DPP - what flight times are you actually getting on the 10s5p pack?

Thanks for replying, mine is coming with the same setup
I am going to try the Thunder Power 10s 3p's until the new TP 2ps are out

Oh, by chance do you know the size of the tail blades that come with it?

I'm not planning to use the 800's suggested as I don't trust NiMH for receiver packs but as to their size suitability my thinking is that I'll only have one flight pack for a while and the Chameleon charger will charge a receiver pack on output II while the main battery is charging out of output I so there shouldn't be any flat batteries.

If you have more than one flight pack though I'd be inclined to squeeze on a battery monitor somewhere just for piece of mind .

I've got an 1100 NiCAD pack which will sit in the 'battery bay' if there is space or somewhere under the ESC perhaps - I noticed that in the video posted earlier the guys receiver pack was in front of the motor possibly for C of G reasons .

I got the Plettenberg which didn't need the shaft modifying at all, it came with a flat already gound on to locate the locking grub screw and the shaft was only 16mm long to start with. I've seen the Kontronic though and wouldn't relish the thought of hacking it about - I suppose the reason for the shorter output is required for clearance of the flight pack underneath? The bay is already only 60mm deep and we don't know how tall the LiPo pack is going to be yet?

Yeah, I'd like to know too 3DPP, what times are you getting and how much charge is going back in to those packs? The theory suggests at an average current draw over the flight of 25A out of a 4.25A pack supplying 10 minutes and 12 seconds but we all know how far theories go in this hobby .

Hi guys
The tail blades are 85mm K&S.
It´s cold outside and the pack has his best performace at 40 degrees so I stopp at max 8 minutes to time and there I load back between 1800mah in soft 3 D and max 2800mah.
May be its more if you fly more pitch, I have 12° for soft 3D and 11° for normal 3D or if you handle the power management not that well.
I use 1500 Lipo cells for the receiver and mount them under the controller, but I´m not shure if it is not to cold in the winter for them, so I will switch back to Nimh.
The tango output shaft was shorten by Jan so I had nothing to do, only to polish a little the gear inside because it was to small.

Is anyone using a UBEC?
I have one in my logo (45V version) and it works fine.

Sounds great, thanks for the tail blade size
Rev. is who I got mine through and they are doing the shaft fix for free with the purchase

Thanks 3dpp.

It look like the flight times are going, at low rotor speeds anyway, to better than I had expected!

I am also going to mount a larger 1100 pack, would be constantly wondering about the 800mah NMhi.

By the way - I have decided to go with Jans built up packs for two reasons:

a) they are £50 cheaper
b) After a long think about it if a cell dies / is damaged in a crash - I can repair the pack cheaply (its not soldered together and I have a good digital voltmeter) rather than risk a total loss for one or two cells.

Looks like I shall have to bite the bullet and hack the end off my expensive new motor, always pains me this sort of thing.

Hi guys
May be it´s interessting for you, a friend told me the information from Jan about the pack for long life is well, but if I don´t fly I should store the pack at 0° C this stopps the chemical process inside.
More warm the pack is more faster he is going older
Mine pack now is sleeping at -2°C, outside from the window.

Shouldn't be a problem in this country Peter, it's that cold most of the year (or does it just feel like it ).

Might be tempted into 'investing' in a small fridge for the workshop - in fact that could give me that excuse I need to get a beer cooler up there aswell . Any health & safety issues about storing LiPo's and alcohol together .

Bring on those batteries!

Well
It NEARLY flew today, just about to take off and noticed the tail wasn't driving properly

The bit of the german instructions I hadn't double checked..

Ho hum ..no harm done

FWIW AUW with 8S2P Gen1 TP4000 is 2.9kg (6.5lb) inc blades.

1 major black mark against the design is the need to replace the canopy when it is "live"

Yup

After 2 false starts, second attempt I forgot the gyro won't initialise in normal .. a tail link later .. finally got it into the air this afternoon.

Must admit I was bricking myself .. HS was about 1300 as I hadn't recharged the batts.
Anyway it hopped up into the air and just sat there ..probably a click of rear trim .. it looks well ..wierd, that long thin canopy is like nothing I've flown before.

Ah ha - you did it !

It flys at 1300rpm??

Off home shortly to redouble my efforts - spent too long on the canopy and its still not perfect, mechanics I am very good with, paint just dosent click.

What rx battery did you plump for?
