|For the evening show he just kept saying "can I have a selfie" every 30 seconds and exclaiming he loves JD and needed more drink.|
Frankly it was embarrassing and I've left a review on the Facebook page stating it too.
Commentary is supposed to be commenting on the show, not exclaiming how cool/pissed/awesome/badass etc you are or how the current pilot won't do what you're telling him to do so you take the piss out of him.
|I never had a problem with Nik Johnson before though, but today I found him annoying.|
Might be one to feed back to Steve Bishop as he's the one organising and ultimately paying out for the commentary...
|We popped down for the late afternoon bit then stayed for the evening show and thought the same.|
I actually thought he seemed like that embarrassing uncle at a wedding who's had too much to drink and nicks the mic off the DJ and won't give it back...
|Thread: 48" Depron Spitfire|
Well, the 3D printer has had a good test at least!
New motor mount designed with the thrust angle built in - pretty much the same angle as with the x-mount and washers but a lot stronger.
Also printed a wedge piece to bring the undercarriage rake forwards which has worked out great too.
Now just need the weather for testing...
I may go mad and 3d print a wedge out. I did wonder if it might need some more rake on the undercarriage to help prevent the tips.
Felt so good to let it fly rather than having to fly it myself if that makes sense.
Might have to do some measuring and see what sort of angle I'm going to be needing and see what I can come up with...
Managed a few flights with the spit yesterday - pretty much zero wind so pretty good for it. First flight was with the 8x6E prop and it ruined the plane totally. Really bad left roll at pretty much all throttle levels and instantly felt tail heavy again.

That's my cameras fault - it date stamped it wrong and I just played follow the leader
I will build a new wing with the retracts in (have a set of eFlight ones ready) but I still need a bit more stick time to get my eye in on this one yet. Slowly getting used to my first low wing plane that just happens to be a warbird too
Quick prop change and tightened the motor X mount bolts as somehow they were slightly loose (might be the cold weather, will keep an eye on it).
Well this morning's weather didn't disappoint at all. Cold at 0 degrees but bright and sunny, even though the sun was in a slightly inconvenient place for finals. Slight cross wind over the runway of about 8mph and gusts to about 12mph at altitude.
I did try and add the washout in the build but it's hard to get it spot on without a full jig. Certainly better than not having anything anyway.
I did do some CG checking this morning after I'd added the radiator covers to hide the flap servos and looking at my plan I think I must have miscalculated it slightly.
Here'e the radiator covers anyway - good shot of the cut down Carbon Copy undercarriage too...
I have a root chord of 316mm if you take the fairing into account or 282mm if you don't. I'd calculated that the spar should be about 90mm back from the leading edge which sort of works out right for a single spar wing and the strength is in the right place no problems.
So my balancing was based on having the spar on the CG point so when I balanced the plane for the first flight it was on the spar. It was very much too tail heavy and I only just managed to bring it in (as you can see from the video). The second flight I moved the battery forward by about 20mm and it was more controlled but I still had to trim the elevator a long way down as any application of throttle still wanted to pull the nose up although not as hard as the first flight. I have about 3 degrees right and down thrust on the motor mount so shouldn't see the level of throttle ballooning I was seeing.
The flight yesterday was a little further forward with the battery but still not massively and the CG was balanced at about 5-7mm in front of the spar.
This morning though I did some working out based on a few reference images of both the full size plane and a few models and I think the CG should be more like 70mm from the leading edge! This could well explain the porpoising I've been getting and general instability in flight.
I've shoved the battery right forward now and I get about 65mm from the leading edge which balances nicely with the plane inverted with the nose pointing slightly downwards (or nosing up if you prefer as it's inverted!)
So, I just need to wait for the next day that the weather allows now to test again. Maybe I can get it close enough to fly without fighting it and hopefully not need to add any ballast!
|Will try CG next time out and I've still got the throws set up to adjust them with the dials on my tx so can tweak them in flight which is rather handy |
Little steps but so far so good for my first ever low wing plane...
Practice makes perfect, going to hit plenty of sim time to get my eyes accustomed to the shape to help me with orientation.
Need to try a slightly more nose heavy setup too as it still felt a touch tail heavy today although not as bad as on the maiden.
After paint I decided to concentrate on my landings and not tip stalling when I come in which I've done on the old spit and this one when I maidened it the other day.
So with a bit of messing I managed to add some flaps and got to test them out today. Yes, I can finally land without tip stalling and actually bring the thing in nicely! No more scuffed wing tips from runway rash!
I did manage to nose over at first and clip the prop though, but a new prop was to hand and I got it airborne once more albeit somewhat louder due to the out of balance prop! I actually was about to abort the take off when the wind got under the wing and tipped the plane up so had to power up to prevent any damage and I was airborne after that. Still need to work on orientation when in the air, but that will come with more practice I think and hopefully better skies too rather than dull and not very bright.
All in all though, I'm happy with the result and I can now get the radiators made on the underside of the wings to hide the flap servos!
Here's the flaps in action...
Happy New Year folks!
You'd love the one from the previous week which was a combination of hard left torque roll and me swearing as it hits the ground!
Maiden completed a couple of weeks ago - found it very tail heavy at first and could probably move things forward quite a bit from how it was on the second flight. Gusty conditions didn't help, neither did the cross wind but it came back in one piece with no damage other than a bit of runway rash on each wingtip.
All in all though it flew well enough and I've now got it in paint ready to fly again, whenever the weather and light allows. This was my first ever attempt at airbrushing too so quite a learning curve but I think I managed it ok!
After crashing my FliteTest Spitfire from it being far too heavy for low wing conditions and having far too much aileron dialled in I decided I wasn't done with the Spitfire just yet.
Here's what happens when you have very little control, bright sun blinding you across your glasses and no idea which way your plane is heading when you get vision back.
I decided I wanted something a little more scale looking this time, but nothing too deep and ideally a relatively light plane.
I managed to find a few plans on aerofred.com and basically took various bits of each plan, scaled it, adjusted it and made a plan up from there.
I came up with a 48" wing span and had two major requirements. Firstly the wings had to be removable and secondly I needed it to be a semi-scale shape as going full scale is beyond my skill set and frankly it would be heartbreaking to end up nosing in after putting in so much work and I wanted more than just a square fuselage.
So I ended up building bit by bit over the past two weeks (since the crash) and I'm now ready to maiden it. No filler has been added, not a lot has been sanded so it's as raw as it can be for the maiden.
I've got fixed under carriage on at the moment but do have a set of e-flite retracts which I might fit to a second wing at a later date.
Hoping for decent enough weather to get it in the air sooner rather than later - we shall see how she flies. You can see more info on each of the pics in the album running through each of the stages in the build.
|Thread: Am I missing something - Flying today|
Definitely seems the majority of the problem I have in the wind now the temperature is dropping is wind chill.
Was flying last night and the wind was up at around 15mph gusting to about 25mph. Not a problem for my fresh build but my fingers were numb by the end of the flight.
I'd love a set of thin gloves with heating elements in - would make things so much more comfortable! Doesn't help that the general shift towards winter is happening now so rather than windy and warm it's just downright chilly!
Here's the plane I was flying last night though - one sheet of depron and some LED strips.
Handled the wind perfectly too
|Thread: Depron 49.5" Spitfire|
Just need to get it airborne in still conditions to get it trimmed in.
It has now lost around 250g since that flight so should fly quite well hopefully.
Typically the one weekend where I was away and couldn't fly the weather was perfect for it!

After the mods and wrapping the wings are now very strong with very little deflection even in Sunday's high winds. I was surprised exactly how well it flew in gusts that were making me shift around in the pilot box.
Just need the weekend to stay dry and a bit less wind is always welcome
