The controller I used was a cheap one off ebay from China. 4 Axis CNC stepper motor driver TB6560. I also got 4 NEMA17 stepper motors from ebay. Metal work was home brew from 25mm tube and some all thread rods. If I build another machine I would pay the extra and use roller ball screws rather than the cheaper allthread rods.

With arduino uno?

Hi sadly I have not got airborne with this setup yet so I can't really comment on how it works in flight. Hold up to flying has only been the retracts nothing to do with radio. The bench testing looks good had no problems.

Not sure I built this one up from scratch

I used Profili 2

Hi Donny, yep getting harder to get the old LPT port machines, I just happened to have one lying around not doing much :)

You can using usb to lpt converter for your new computer :)

It's a thin foam board

Thanks for answering. What program are you using to layout the ribs and place them and if you don't mind, what program are you using to cut with? Thanks again.

Hi Ken I left the standard motor. Pulls beautiful with stock 4 blade on 4S. Should ship for 4S.

+Mick Paul ive been flying mine that i just bought at auction with stock motor and esc with 3s 2200mah and slow as shit.

+Ken Pappas yep pretty slow and boring on 3s. I have my throttle limited to 75% on 4s to keep the current limited to the motor, and it flies great. I will never put a 3s in it again.

Can you take a pic as to how you mounted 4S and where please.

Renix Charles Hi Renix, I think as the motor is only really to get initial launch altitude (and emergencies) the load on the motor (duty cycle) is quite low, one thing to check is the ESC is rated to take the amps ESC will typically die before the motor if it's not capable of taking the load. I am flying many of my (3S) models on 4S, as are many of my friends, to date all have been fine, it is really important to check the load with the prop, couple of models we have "throttle" limited due to very excessive amps. Heat is the danger so keep an eye on the temperature on some ground runs also if you can.

Renix Charles Hi Good question, and yes there is some increased possibility the motor will burn out. Per these motors it's difficult to know what their maximum rating is when they ship with the model, little or no documentation. Going from 18.5 amps (192w) to 27amps 378w) = 46% increase. I don't fly it on 4S and have found the best change was to increase the prop size and keep the original (lighter) 3S battery. I can't remember the thrust difference as I did it too long ago, but moving to 12" prop improved the powered flight a lot! And with very little additional load on the motor. First flight on the lager prop was just "wow", much nicer.

WorksopGimp Hi WorsopGimp well RF does not radiation (or is at minimum) off the end of the antenna, so if the antenna was extended and pointed towards the model that would give the weakest signal. On my taranis I extend it just a small amount (when I remember) because the return loss (VSWR) or SWR for old CBers is best when it is slightly away from the case. Hope that kind of helps.

That test was with the stock ESC. Since the test I have replaced it with 60A ESC and fly it on 4S only now. MUCH nicer to fly on 4S ;)

Keith hello! I don't know how I missed your comments (from over 1 year ago)... Yep another flying wing :) How are your models flying?

Mick Paul hi Mick this year's been a bit slow. Son got married and wife's had operation on here ankle so not had very much time. Trying to get the Hurricane completed. posted a video last week that I finally managed to done. Wing is still flying great. how's your CNC going

Think you mean Gimbal :). I have one but won't put it on the Nova until it has been flight tested properly, I was even a bit weary about putting the gopro on it. If you look at some of my other videos I show the gimbal being tested.

Hi Aaron sorry I didn't see your first message. Yes the internal Taranis module is compatible with V and D series receivers. You can find a very good list of Taranis compatible receivers and their capabilities on alofthobbies website and also on the openrcforums.

Hi Aaron RC, I'm using the build it module in D16 mode. No additional module required.

What is the range?is it okay for huge turbine rc jets? The built in module can support up to 16 channels by binding two x8r's together right?

Hi Aaron, I don't use any external module. So it it used exactly as it was from new out of the box with the internal module and fitted antenna. Does that makes sense?

Aaron .T 1 Million Miles!! More than you can fly in Twenty Minutes......I think :-)

Hi Douglas, after so many flights with the FX79 in all conditions without any stall or dramas this happened - completely out of the blue (2 times in the one flight)....

Hi Keith yep you and I both, thought it was going in for sure. No response to any stick inputs, just a spiral dive like an arrow. Brain was telling me inputs (opposite to what you think it needs), but nothing, it was like it had no receiver on-board, regardless of inputs it just continued falling like a collapsed kite and it didn't look like it would recover. I was about a 100th of a second from giving up when it finally came out of the spiral dive like nothing was wrong. I'm gong to put that video up again with audio :)
