    @JAB1a I've got 410mm centre to centre on this and at the moment will be using the same motors which could be interesting

    Can always swap the arms out for longer ones if needs be there is just 1 m3 bolt and a nylock that holds them in.

    excellent @plexer, using the same motors will give you so much power as long as you keep the weight down. How is your other quad build going? did you manage to sort out all the wobbles?

    Here is my TeslaHex build...

    This is the first part of the build, just testing the frame...

    Here is a comparison between the Skywalker 20Amp ESC's and 1000Kv motors from my big Quad compared to the mini 12Amp ESC's and 2500Kv motors of the mini hex

    Hmm interesting, I didn't think they did a slim version of the 12Amp due to them already being so small compared to the 20/30Amp ones, I will have a search around

    Minor setback, second set of test flights resulted in liftoff and then spectacular pile in thanks to 15 degrees of aileron applied by controller as default (thought I had checked, whoops). Broke all props, one prop mount lost, one motor mount broken. Next test flight will be done strung between a couple of trees. Lesson learned.

    Probably spent another 35 buying a replacement X525 frame (woo, loads of spares), prop mount and props. Should be good to fly again this weekend. Until then, here's a pre-crash photo with my wife's 1:72 scale airfix spitfire project (she wanted to build something too and we were in the model shop)

    Wow, looking at all the progress being made in this thread has well and truely put me to shame. Since my last post, I have made exactly zero progress on my main quad. It's still hanging up waiting for me to finish the wiring so I can connect the FC.

    In the meantime, I'm still having fun whipping the Hubsan out every now and then and having a fly around. I've gone through 2 motors, a few props and a whole new shell. Oops. Ended up making a 5 battery charging harness for it too meaning I can fly around the house for longer, much to my wife's disappointment.

    @TwoZeroAlpha the build is looking good, shame about the crash but its all a learning experience. The X525 is a great frame with modifications, might I suggest you get rid of the horrible/flexy/brittle motor mounts and mount the motors directly to the arms, it reduces so much flex and vibration and you wont end up breaking the mounts everytime you land hard. I used one of the holes already there for the motor mounts and drilled another hole to fit the motor (also a large hole between the two screw holes for the motor shaft to fit into)(get rid of the horrible soft metal X motor mounts that came with the motors).

    With the frame plates, turn the extra little third plate around so that it locks the arms into position restricting the folding action, I have seen quads drop from the sky due to one of the arms unexpectedly folding away lol, not nice to see.

    I also swapped out the ali arms for stronger ali arms as the metal they used for the red and black arms is just one stage above tin foil lol, the swap added 80g to the flight weight but made the quad feel like it was on rails.

    I can't wait for some time off to get stuck into my own build, bring on Xmas!

    Forgot to add, I did eventually get a camera attached the Hubsan! It was a little heavy though even without the battery making the flight a little sluggish.

    @Ant lol wicked news that your still playing with the Hubsan, it will put you in a Very good state to then fly your large Quad. Did you run into trouble making your quad or was it just a lack of time that ground you to a halt?

    Just lack of time and priorities I'm afraid! We're doing some redecorating too so there isn't the space for me to leave all my soldering, wires, and bits lying around to have a dabble every now and then. BabyAnt will be making an appearance next year too, so my mind has been elsewhere!
