Thread: Hitec Aurora 9
19/08/2015 21:09:05

Hi Victor,

Had a similar problem with my current TX (ff9) which was 35Mhz Futaba could not find a fault but changed the module as a precaution. No further problems have been encountered. Still use the ff9 but with a hitec/futabe 2.4 module as I hope to get an aurora 9 some time in the future.

All the best with the move.

With the amount of building experience (or lack of) that you had at the start. I think that you have done a remarkable job so far.

Please box what you have built and wait for the mojo to return.

Hope to restart my build soon and I have yet to finish the wings.

Not sure where all the time has gone, although been busy getting a lot of little jobs out of the way. None of them model related, still have got to the stage where most of my free time is available to hobbies.

Have now started to fly regular (weather permitting), so a few maintenance jobs on some airframes, legionnaire to fit radio and test run engine. May assemble an artf and get ready an acrowot.

Once I start building the chippy again I hope to make better progress.

Colin, it would appear that it is only in one panel, but it is only a small amount 2 or 3 mm. May try and correct when I sheet underside. Pretty sure that a little bit of trim on test flight should sought it out asking as rest of airframe is true.

07/04/2015 13:28:39

Thanks for the heads up. I will make legs as per plan and adjust where needed. More than likely to post photo before final install, as once the sheeting is added then a lot of work to try and rectify any problems.

Does any see any problem with leaving the little bit of offset in the wing build mentioned earlier in blog? personally think that it should not affect general flying overall to much, as not expecting to do any precision aerobatics.

Thanks Colin, I think that I may have some brass sheet lying around. like the idea of the triangle section between under carriage ribs and LE.

Was considering mounting the front part of the leg in hard wood block with a piece of tube rather than P clip.

Yours is getting along quite nicely.

Still awaiting oleos from HK first set never arrived! I intend to build under carriage as per plan then trim to suit oleos if they arrive. If they don't turn up then will look for an alternative or may just go with standard piano wire legs.

just out of interest what have people used for the retention straps?

05/04/2015 17:14:31

Both wing panels built but only top surface sheeted

wing top sheet.jpg

I have checked the measurements for LE, main spar and TE. The main spar is ok but the LH LE is 1.5 lower than the RH and the TE is 2mm higher than the RH. I think that the problem is with the RH panel, I may attempt to correct this when I sheet the underside. If this does not happen then I think that a little bit of trim applied to the ailerons should sort it out.

Will start to take a look at the under carriage next.

The basic for the RH wing panel now complete.

Managed to use the large permagrit bar, did wonder if I would ever find a use for it.

dscn0049.jpg

Was a little concerned with the angle as I could only get 52mm measured under rib 18. However checked the

length of spar and double checked using simple trig and at 52mm this gives me 3.925 degrees.

dscn0048.jpg

There is a very small amount of warp starting from rib 15/16, not overly concerned as this is producing a very small amount of washout. It may well disappear once the panel is re-pinned to board for sheeting.

dscn0050.jpg

Needed to alter quite a few of the ribs to allow the top spar to line up with lower spar. Without this been done the panel would be warped.

dscn0051.jpg

Guess who didn't look for B1.

Will revisit RH panel to sheet top and then profile under side once centre and LH panel built. I intend to add the centre section next then will build LH panel onto the centre. I will leave the shroud etc off until the hinges for flaps and ailerons are done.

Definitely prefer to build three sections then assemble, it allows much more freedom to ensure everything is correct.

With all the additional work to get spar and ribs to fit, not to mention adjusting the dihedral brace it seem to take an age to get this far with the wing. However if the centre and other panel turn out like the LH I will be pleased and should have a reasonable base to finish the wing.

07/03/2015 10:44:29

Gents, thanks for the replies it is encouraging that the warp should build out. I think that this may be part of the reason that I have not been in a hurry to start the wing.

Although I have traced the wing for the LH panel I may just try the meths, as it should be more accurate.

A few words of encouragement do really help get things moving.

Well of up to the loft, will start with a dry run and do any final fettling, just need to decide on what to listen too.

06/03/2015 20:55:46

Checked the dihedral brace and a little sanding has given a reasonable starting point.

dscn0038.jpg

Holes for control rods, doublers and building tabs added to all rib.

dscn0044.jpg

Rear spar glued and filled

dscn0045.jpg

Glued the lower spar to the first dihedral brace, this is a starting point.

Used straight edge as a guide to pin spar, I use dress making pins and a panel pin hammer for securing the main spar

dscn0047.jpg

I think that the warp in the dihedral brace will be removed once the other spar and ribs are in place!

dscn0046.jpg

Hope to get a start on the wing over the weekend.

Colin, your not on your own with regards to taking a long time to not do very much! Your way ahead of me, just about to start the joys of a Dennis Bryant wing.

Yours is looking good and closer to having a complete airframe ready for all those lovely rivets!!

Quite happy to go with the spruce for the undercarriage, but not to sure about the main spar brace is a little warped, not to sure if this straighten out once the ribs and spars are in place?

It's been a while since last had a chance to do some building for various reasons.

Was getting a little frustrated with lack of progress, it seemed to take an age to get fin and rudder complete. I felt the same way about the tail plane and elevator.

So have decided to move onto the wing to try and move the project along.

Filled the wing rear spar with Roket powder, this seems to have worked quite well and do not think it will need any additional beefing up!

At present just sorting through a few tasks in readiness for the wing build and have noticed that wood I intend to use for the undercarriage mounting blocks is spruce rather than beech. Does anyone have any misgivings with using spruce for this task?

Just like to add my thanks for the photos.

With all the work done by Danny and all those that have nearly complete airframes I don't want to let the side down, so must really get some building done.

Just starting to do some prep work (getting up to date with other blogs) before starting on wings. Progress very slow due to having to sort out a few things. Hope to push on once wings get started.

Fin and rudder now complete with shroud.

fin rudder.jpg

Using the technique that Danny showed was very effective

rudder shroud.jpg

Generally quite happy with overall appearance, however the transition from top of fin to rudder seems to be about 1mm. Not sure if this is and the general fit of the rudder/shroud or correct. Not sure if any further work will be done on them as the intention is for a stand off scale, however lesson learnt.

rudder transition.jpg

Just about to fit shroud to tail plane but will await any feedback so that the evevator/tailplane transition is correct.

In the mean time will start to have a look at the wing.

Hi Scott,

If you were the parent how would you like to find out?

Hi John,

Thanks for the information and apologies for not replying sooner. I have also done a bit of research and according to the pilots manual for the chipmunk the control movements are as follows.

Aileron up 21˚ down 16˚

Flaps 15˚ and 30˚

Elevator up 38˚ down 15˚

Rudder 31˚ each way

After transferring the angle for the elevator to the plan 38˚ seems to be quite a lot?

A rough check for the ailerons give 20mm of up movement for 21˚.

elevator movement.jpg

It would seem that if 38˚ was used that would give nearly 50mm of movement

It will be interesting to see what we actually end up with, at the moment I would be thinking of those airsail movements. I daresay we will have a few maiden flights from others before i have to make any decisions.

Anyway not any chance of doing any building today, off for another dinner!!

Happy Xmas to all chiperteers.

Have enjoyed the blogs and learnt a few things.

So all the best for next year and hopefully a few maidens (flights that is).

All the best SW
