Paper Plans Pour Perfect Pixies
Just had an email back from my mate Derick who sells plans on fleabay - cost to us on MZ is £5.00 inc p&p within the UK.
Plan is A1 sized and on high quality paper.
Address is ...
modelplans@flyer21.plus.com
Use that for PayPal payment too - just mention in the message what it's for.
Once the design/name is finalised, I'll send him the updated PDF - probably best to wait until then.
Cheers
Neil

Done, just added a 'Mode Zero Goblin' plan topic in Documents - don't know if it's sticky though. No doubt there will be more changes anyway - as well as the name

Seems to work fine.

Re: Recreating the Irvine Pixie S/C or intermediate glider
Please can we have a scale on the plan somewhere?
I always need to check on my Epson'n'Sellotape printing that I am actually getting the plan at full scale ie 10 cm on plan is actually 10 cm on my print out
Regards
Gordon

Re: Recreating the Irvine Pixie S/C or intermediate glider
I don't have access to a SC friendly slope within a reasonable distance, I do have half a dozen Cox 049s, and, EP systems to mount on a removable power pod. What angle up thrust would I need to power a rudder only MZ Goblin?
Cheers,
Dave

Re: Recreating the Irvine Pixie S/C or intermediate glider
From memory, it's around 30 deg either tractor or pusher.iflylilplanes wrote: ↑24 Jul 2018, 04:37 I don't have access to a SC friendly slope within a reasonable distance, I do have half a dozen Cox 049s, and, EP systems to mount on a removable power pod.

You could always start at 90 deg and work your way down until you get horizontal flight.

Re: Recreating the Irvine Pixie S/C or intermediate glider
Version bv1.04 just uploaded - some minor errors fixed and scales added.
viewtopic.php?f=8&t=429
I'll leave it for a couple or more days and if there are no more changes, we can nail it at that.
Other than the contentious name of course

Re: Recreating the Irvine Pixie S/C or intermediate glider
I just checked my Bixler 3 (it's a pusher) approx 30deg downthrust - same for tractor except upthrust.
I feel there may be a great aeronautical argument blowing here
However, having tried a google search for interest, I can see tractor pods having thrustlines from about -1 to 35 deg !!
I have an old Graupner Cirrus power pod in the attic somewhere and it is around 20 to 30deg.
Be careful when looking on google, a lot of the pods have flat bases and were designed to be banded on to the rear portion of the wing section, so depending on the aerofoil, it will give differing angles of upthrust.
Perhaps an empirical approach starting at 10 deg would be good - probably best with a switchable e.power first

Re: Recreating the Irvine Pixie S/C or intermediate glider
I’ve always just set them to the datum line, zero degrees, never had any problems with impala, soarcerer, little V. It only uses the power to climb up to altitude then glide down anyway.
