Added a couple of additional tabs to the spinner backplate with rivnut fitting to allow two opposite support fittings for spinner … These provide additional rigidity to the existing centre bolt fitting
Trig Radio and Transponder bits going in … Cut dash to accept both heads and fitted the base behind the pilot seat. Cable routed around body struts and now removing the pre tinned bits I did as Adrian advised me that the crimper will expect to crush onto cables NOT tinned .. Which might prevent proper crimping !
Manual in hand and pins and crimper at the ready .. Adrian also advised to butt the outer cable close to the end of the pin
Many thanks to Paul HS for the kind loan of the superb Crimpers !
Update 6 June – OK – I worked through the night the other night – all excited to get to this part – makes it so much more real …. and, having crimped on the females to the radio thought lets crack on and use the remainder of the pins to do the Transponder … Oops – managed to use the wrong gender (females) so am now short of said item.
Looked on RS and wasn’t sure they looked the same and no one in Jersey will have them I guess so a quick call to Trig. What an amazingly helpful, polite team they are… lady answered just before 1800 (and I thought I might have to leave a message). She kindly passed me on to James who couldn’t do more to help .. sure he would pop some spares in the post – tomorrow OK ? – simply perfect !
We also had a chat about what aircraft they were going in and how it was progressing and the sort of support they offer after sales. Really good solid Company ! Many thanks guys.
The LAA kindly followed up on my penultimate submission (Jon Viner .. He’s really good and responds by email almost by return) .. The ‘final’ bits they want are some photos of the carb heat fitting and also evidence of how I know it’s working … I plan to put warning lights on the panel for both heater elements …
also photos and description on how I have secured the tail ballast
My original taxi checks had proved interesting as what had seems like good brakes turned out to be quite soggy !
Mike and I had a look and tightened up a few parts so they became much more firm and solid affair.
So these were re tested today. Took the checks away and started her up .. She start so sweetly … First turn every time !
Then waited for the relatively busy area outside the Jersey Aero Club to settle …this area is a strip of Tarmac in front other hangers quite short and quite narrow … Should be a good test and if it all goes to pot .. Just shut down .. Jump out and turn her by hand.
i should not have worried … I temporarily disconnected the steerable Tailwheel to leave her castoring and, with differential brakes, she nipped up and down .. With careful but beautifully tight right hand turns. The Stampe used to react quite positively to blips of throttle but I don’t want to use too much in such a confined space with about 8 aircraft all around.
Spent a very happy 20 minutes going up and down and around to the left then around to the right .. All turning in her own length ! great .. And I feel so much more confident now about popping into the active taxiway at Jersey … Don’t fancy holding up and Easyjet of BA airbus whilst I ground loop ?!
At the end of 20 mins I stopped as I could hear a graunching sound .. Turned out to be hot brakes ! but hey it had been on them the whole time against power … Very pleased with the result !
Yesterday saw a very productive session whilst I await radio and transponder arrival.
Months of barn and hanger residency has meant a build up of grime and dust and dead fly bits all over the Oratex … Being bright yellow it looks great anyway .. Until you wash one panel and dry it .. Then it bounces back to that lovely smooth clear soft supple finish !
This did give me a chance to go over all the ironing bits again and I noticed a few places where ironing the doubler pinked strip down had not taken as well as it could. I remember at the time that I didn’t want to ‘drag’ across the pinked edge as the heat could distort the points …. So it was more of an action at 90 degrees so that the points of the pinking all held their shape. Now I could see that some bits were just standing proud. Small shoe iron back on (thanks to Danny B for helping me source this .. It’s been fantastic and pretty much completed the entire aircraft just with that !) .. And at about 145 degrees and it all seals down nicely.
Then I re checked the connections for the EGT and CHT as these had played up on the Infinity. First of 3 engine runs got one of them working … Realised that I needed to re check the set points and thresholds for them. By the 3rd run I had 2 x EGT working on a scan basis and 1 x CHT .. The other CHT just has a flashing arrow pointing down … Either it’s a bad connection or a duff sensor. Will follow it all through to check.
having now removed the standard Jabiru RPM and spliced int the charging circuit in my ‘hunt’ to get an RPM reading on the gauge I find I still can’t get a reading. Checking with Danny to see what I’ve missed … Last part in this wiring puzzle … It’s not my strongest point but hey .. Nearly there 😄
I have had a few problems getting successful readings out of this and, on subsequent re reading of the instructions I noticed that on a page very near the end of the document it mentions that if you intend to monitor both EGT and CHT then one MUST wire before the other .. And I had it the other way around .. In terms of channel numbers
As all connections have been put together with hand shake connectors it’s easy to review and change sequence
I have also struggled to get ANY reading from the RPM sender unit which was factory fitted photo cell …
Contacted fellow builder Danny (Baker) who advised that he used the charging circuit and set the pulses to 5 and it works a dream. I will look to change mine over as, after about 1 hour 40 mins running on sense and sound alone, I need a proper gauge to check RPM
Ordered the last bits ! Trig Radio and Transponder from Paul and the wiring harness that TLAC have a fantastic layout board for
This is now loosely in the aircraft and I have tinned all the cable ends in readiness for what I gather is the crimped method as you build up 15 pin and 25 pin D plugs for the kit ..
once this is in then I can get sides covered
I wrote to the LAA sometime ago requesting that I be allowed, offering my 80 plus hours in the Stampe SV4 and around 12 on the Chipmunk (ex Air Atlantique – Mike Collette – local Jersey resident)
The LAA quite rightly asked how ‘recent’ my time was and on checking it’s over 7 years ago … I know it all comes back very quickly .. BUT I do t want it coming back during my FIRST take off roll !
I called Paul at TLAC and he kindly arranged for Howard (Barbour) instructor, to sit with me through some circuit bashing. Three dates came and went as the weather earlier this year confounded every attempt. Then, in April we finally cracked it .. The grass strip was waterlogged on the Thursday but dried ok for the Friday BUT we then had around 20m viz and a base of about the same !
On driving up to Little Snoring you just felt it would lift … And sure enough by 10 am it did to reveal lovely fluffy white clouds
Howard kindly let me do it all from the P1 seat and we took off a lovely grass strip in G-TLAC for some initial upper air work. Such a benign stall … Then back into the circuit for some classic lovely tight right base approaches … What an unbelievable wonderful fantastic aircraft this is to fly … You strap the ‘plane onto you ! not you into it ! you just think of the turn and she goes …. My second approach below
The first approach takes your breath away .. Then you get into the groove and happily wing over and roll her out into a very short final .. Flaring out for my second attempt and so so close to 3 pointer … Then I got slightly excited and pushed a little too far forward on lifting the tail on take off .. Howard gently reminded me of the angle I should be looking for …
We had around an hour then landed for a breather then up again … Normal circuits in Jersey involve longish straight in approaches so we tried a couple of those which makes you realise that seeing over the nose is tricky so you side slip … We tried a couple of long ones of these with a nice little kick straight at the bottom of the roundout …decide I hate long straight in and prefer the much sportier tighter approaches !!
After some amazing approaches Howard ‘kindly’ chopped the engine and said “power failure” .. Cheers mate !! I hauled her around and kept the nose down to keep the speed up but it was going to be tight …. Landed part on the taxiway and part on the grass strip … Nice and gentle .. Howard advised I could have pulled harder and she would have carried in turning to make the taxiway !
Howard then left but Paul was happy for me to do a few more with my son Sam who quite rightly had a go … Loved the responsiveness !
LAA have indicated that this will be fine for allowing me to test fly her out of Jersey… Happy days
Having set the starter button (decided against a key start – something to lose when you are travelling !) on the right of the dashboard and the two mag switches .. I noted that the two Trig panels that TLAC now produce would look much better if I put radio one side (right is logical – keeping the left hand free for throttle) and transponder on the left side.
This meant I had to re locate the starter and two mags … Sam, my son, cut a piece of dural and shaped it to fit nicely as a side panel to hold all three, drilled holes and then helped disconnect and extend the leads to allow the slightly longer run.
This gives a nice easy access side mounted section for all things starter related
