Tbh I've been really busy, not had much time to fly anything and with conditions being crap, hopefully in the new year I'll have some new projects on the go, mostly to do with HAM radio, will certainly fly again soon. FTR I hate FB too   :D Merry Christmas

My first brushless 75mm , snapper 7 .

A few comments , and of course a video.

Had been rather disappointed with brushed whoops two years ago - low power and voltage sagginess - much more impressed with this craft.
my first ever ( barring a Syma x5 back in the day ( still flies !!)) ready built ,but at £60 complete ......
Motors and batteries seem to be holding out ok , the motors seem to have extremely fine tolerances between rotor and stator .
Whole craft has took a beating over maybe 100 flights , frame bends back well , but one support arm is broke.
Camera has had its share of impacts but always goes back togetherish.
Feel the aio has got better since two years ago.
Will be trying a cloverleaf antenna.
As for flying with prop guards - what a delight !

Main attribute is lack of noise , and along with that , I feel ,slightly less offensive / scary to non-flyers.

Still getting over 2 mins aggressive flight from well- used batts. ( over 3 mins @ new)

I do find it amusing -
my (old) 4" 180 quad with its £20  , 4s 1300mah @180g
And
This 2" 75mm with its £4 , 1s 450mah @14g
Similar flight times.

Finally I must give respect to betaflight and especially its osd and the interactive on - screen elements for pid tuning.
( have been an open/ librepilot dinosaur up til now )
Spent ages messing with rates ( impressive curves available) but then went back to my old linear/ no expo
Will add flight vid in following post.

Cam isn't quite as good as it was - lens has been damaged and loosened on occasion .
I feel that recording with the fatshark Dom v2 in built recorder maybe isn't best . .?
Also this is 25mw and a plain stick antenna.

That's quite impressive. I didn't think you would get that much performance out of it.
You have extended my search for a micro. Thanks.
Nice flying.
I try :-)

Ern Stock

Thanks
Am now considering a mobula 7 , ( currently £75 inc 4batts) same thing but with a 2s board , lighter frame.
Very unscientific of me but I feel that 1s batteries have some sort of inherent weakness. Am happier when the load is shared over several cells.

I had been looking at things like the Diatone GT M3 3" and while it has decent components and I doubt I could build equivalent cheaper but it's getting reviewed at over 100mph!!!! Which I think would be too fast for me. They also do 2" and 2.5" versions but they are still doing over 80mph!

Ideally I am looking for something that I may be able to fly round the garden to get some stick time but still able to have a good thrash round a field when I get the opportunity.
So maybe the Diatone GT M2.5 running 2S in the garden and 3s or 4s in the open?
I try :-)

Ched just so you know the GT M2.5 is exactly the same as the GTM2 I built which you've seen on my post....I contacted Diatone to ask what the difference was between the 2 and the 2.5 and the frame on both is the same it's just the baseplate that has slightly larger arms....They told me I could only fly with 1935 props but actually you can 'just' squeeze 2035 props on it  ;)

Speed is relative (!)
And of course pretty much entirely dependent on camera angle.
I find it more exhilarating flying agility-testing rather than 50mph + up in the sky .

I pre-ordered the mobula7 and got it yesterday....it is next level compared to my 75mm 1s brushless whoop.
it's the same weight before batteries, 28g.  Absolute bonkers.

FYI the eu-lbt version uses an XM+ which is really great for range but it's extra weight. That version comes with the FLYSKY fc which you can just desolder the XM+ and use flysky protocol.  Then sell the XM+ to get some £ back or use it on another craft if you can! (easily flash it to fcc if needed)

Maybe we need a bit of a Daich review  ::).

Yup let's see some flights on the mobula !
Edit - just seen it on "did you fly today" thread - ace!
Sounds like good tip re the rx ( am on spectrum myself)
