I have built a Pulsar III from a virgin kit. Great little airplane. If there is any documentation I can provide from my files let me know. Cheers

Hi guys, we're another new member to the family after purchasing a new unused Pulsar III kit here in New Zealand late last year. The Kits been in New Zealand for a long time and almost all there, of course some of the components like resins etc have been thrown out but very happy with condition overall.

So far its progressed very well with the fuselage almost completed with newly machined Aluminum undercarriage replacing the fiberglass component, Horizontal and vertical stabs all done. Luckily one of the team does composite's for a living so very comfortable where we're heading and having an engineering background and a few previous plane projects with a Mill and Lathe also helps of course. The kit was basically complete up to the fire wall and we've been keeping an eye on this forum these past months and very helpful thanks. We were able to take a mold off another pulsar for the cowling so sorted there and we've decided on a 3300 Jabiru Gen 4 and the Aussies can supply firewall forward kit at a reasonable price.

What we'd like to find out is whats normally used for the firewall as there is only a sheet of thin Stainless steel and no details with the kit, is there a plywood or honeycomb bulkhead then the stainless covering that? All the engine mount points are detailed so that's understood.

BTW would anyone like me to post a few photos of our current stage of construction??

cooling jabiru 6 cyl engine

mike timewell
 

Hi Everyone,

 

Request for advice from those with Jabiru 6 cyl engines:

 

Have you had /do you have heating/cooling issues?.

This is my first year with cool weather flying and pot temps seem rather variagated.

 

I have a Pulsar III standard cowl design and the engine is overheating in summer on normal to hot days of 20 to 35 C.

Temps are higher on climb out and can take a while when levelled out to get temps down to within acceptable limits .

I do shallow climbs but still high temps on cruise in summer especially on pots 3 &5.

 

Winter is here now giving me good temps on cylinder so overheating no issue but  1 cold cylinder at 77 degs!! Any idea about that? Its definitely low.

I have not started touching the engine yet as I may be wasting time going on  the wrong track but first thing will be check the CH temp probes (which go into the cyl and not under the spark plug) for connection issues.

 

 

Winter temps (air temp on grnd 10 degs C) in cruise 2890 rpm 5 mins after T/O at 3000ft

 

Cyl 1

2

3

118

146

166

 

 

 

Cyl 4

5

6

70

165

144

 

 

 

EGT

683

644

OIL T

76

 

Oil P

49

 

 

Jabiru advise Temps should be 150deg C IN CRUISE AND NOT EXCEED 170C and all within 15 -20 degs of each other. My temps vary more than that.

In summer the temps are higher with pots 3 & 5 around 170 to185 deg C in cruise.

 

My ship has standard baffling [ from what I can tell from pics of jab 6 cyl installations] and the std plenum. There are no “plates” wired down between the cylinders & block. I bought some and will likely put those on in summer unless someone thinks they help in evening out temps.

 

Have not tilted the ‘carby’ yet.

Have not changed jets. Am  (using 5.25gal [21 litres] per hr at 2850rpm)

The oil cooler has been altered [see pic ]and not sure if this doing anything much at all. Is it cooling the air in the engine bay or heating it up??

 

 

In conclusion Temps seem rather unbalanced and running too hot in summer / uneven in winter

 

Any direction and advice is appreciated.

 

Cheers

 

Mike

Re: Navs & Strobes

I used Aero lites BA15 LED bulb replacements in my old whelan nav lights. No controller needed. They strobe or stay on by flicking the off/on switch. 
This is the bayonet type bulb. 
Very cheap.

These Whelen Vertex hide-away strobes are approximate bolt-on replacements for aviation strobes.  Built-in drivers allow for the selection of multiple flash patterns.  They’re relatively expensive but are very bright and are quality builds.   Typically about $100 each, these are going for half that.

I just used the standard 12" hose and attached it to the side of the engine cowl. I did use an electronic sender as against the standard mechanical unit. Sorry I don't have a photo.

Cliff, I like your grease gun hose approach.

Do you have a picture to share? Is the hose you use standard 12" or are you using 39" (1 meter) long hose so you can install sender to firewall.

A Simple Strobe

Bob Hartunian
 






A Simple Strobe

I finished a partially built Zenith 701 STOL that had Aeroflash strobe power supplies mounted near wingtips with no accessibility provided. Sure enough, when plane was finished, one strobe didn’t work and I could not get into unit to fix. Decided to make my own strobes from simple parts.

You can buy a strobe unit intended for search/rescue purposes for $5 each ( https://www.quakekare.com/emergency-strobe-light-p-45?gclid=Cj0KCQiAkKnyBRDwARIsALtxe7j4z_xEZrBx0EVx1hRgzOYaXuZw3cOU_1aDBW7Ce4Vd5MDB_3ZtD04aAuKZEALw_wcB ). ( Figure 1).  Works from a 1.5 VDC D-Cell battery and pulses at one flash per second. The strobe bulb has all the circuitry built-in (Figure 2). All you need to provide for operation is the 1.5 VDC from ship’s power that requires a tiny step-down voltage regulator.

Amazon has miniature adjustable DC voltage regulators for $1.50 each. I bought a pack of 8 each for $12. Only needed one to power both strobes at wing tips. (  https://www.amazon.com/LM2596-Converter-3-0-40V-1-5-35V-Supply/dp/B01GJ0SC2C/ref=sr_1_20?crid=25YLYBVX9OES6&keywords=dc-dc+voltage+regulator&qid=1581957870&sprefix=DC-DC+Voltage%2Caps%2C210&sr=8-20  ) (Figure 3).
Mounted one regulator in cabin and ran a single 22 gage wire out to each wing tip. Output from the regulator is split between wires. I set the regulator adjustment to 1.6 VDC output to compensate for any voltage drop from wires.

The hardest part of the job was to adapt the strobe bulb to the existing wing tip light bracket (Figure 4). I cut away the sides of the bracket to allow the wider bulb to fit. Bonded the bulb to the bracket and soldered a wire for power and ground to the bulb. Used Bondo to fair in the bulb to bracket. Mounted the brackets back to the plane and turned on power to see each strobe flash every second. 

The strobe bulbs are smaller than a normal Aeroflash unit but you still get an actual strobe flash that would satisfy an Experimental anti-collision requirement. For the price of ~$12, I have strobes working at wing tips.

I have had the same problem for 24 years.....I think it's just that the stator doesn't have enough output power. Instead of reading the absolute number I just use relative readings to know its normal.

Since I installed the new Stratus Transponder this year, it draws enough power that it will sometimes shutdown at low engine power, like landing configurations. If the Stratus doesn't have enough voltage it shuts down.

Thanks

On my XP with 912S the oil pressure gauge shows less pressure when I turn on the running lights and goes lower yet when I turn on the strobe lights. I’m sure it is a electrical load problem, but where do you suppose it originates?  Ground? Poor connection? Corroded fuse? Other?

Thanks Mark,
I’ve not been worried about it either. I just thought maybe it would be a simple fix. If it wasn’t for added weight I might use the grease gun hose connected to an isolator then a mechanical gauge.
