Oh and my model came with a hole in the bottom. I use it for the ignition battery as that sits under the tank. 

 

Looks nice have you one of it completed

I have the exact same tri- Square that’s on your bench. I got from my dad, mine must be 60 years old ...if not older

[Paul De Tourtoulon]

And me, but can I see an adjustable spanner on Jon's table ?.

[bert baker]

I’ve been looking at the various cowls I have to hand

 

whist not wanting a long scale debate as for me it just covers up the engine I’m wondering where a all the variants come from and who produces them,

 

It’s quite possible that some or all aren’t actual Stampe ones,

 

Perhaps  a Moth Or a Chipmunk I care not

 

I know Carbon copy did one in glass cloth

Errrrmmmm

Dare I say it,

A Zenoah G38 on a reduction drive

my Big Moth has same setup but is the variant for the moth 

The Dawn patrol and many others use the G38 and reduction drive, My first Pup kit had the firewall machine cut to take the G38 and reduction drive 

The Practical Scale moth Advert always said you would regret not fitting the G38 and reduction,But they did fit a 60cc four-stroke later on, I have one to fit as I think the prop on the Moth is to big for the plane but want need to scratch the itch 

 

plus I need to cut a large hole in the firewall to take the four stroke

There’s one built for sale

I have a Slec cowl. Pretty substantial 

[Steve Dunne]

I too used the SLEC GRP cowl - very substantial, and I was easily able to cut hinged access doors from them.

Recommended.

I’ve been lazy for a while now of doing stuff 

I was going to fit the Laser 180 into one of my Stampe’s but just can’t be bothered with the fuel tank issue, it would be easier to modify a new kit build, but I still Would prefer to go petrol,

Dan’s in the proses of getting one airworthy with a Saito 40cc four-stroke,

I’m half tempted to do the same but did happen to notice the OS 40 petrol four-stroke is slightly cheaper but may be a bit lower on performance of the Saito 
 

 

[Peter Jenkins]

My experience of Saito 180 is that it's of average power but vibrates like crazy.  The 150 has slightly less vibration but OS 160s are as smooth as silk and don't spit their silencers off on every other flight!  Oh, and yes, the prop was balanced!

I have no experience of a Saito 40cc petrol but my Saito 100 is smooth as silk.

It might be wise to see if you can check the vibration on a Saito 40 cc running.

Just saying.

I may be ridiculed .....but the Evolution 33gx fits nicely in the cowl, just a small piece of muffler on the outer port side. The downside is its not a 4t. NGH 30 maybe? If you can find a good one.

[Paul De Tourtoulon]

I have the Saito FG-30, other than the weak con rod and first star bubble issues it's a dream to fly and hear.

[bert baker]

 

I’ve got a NGH 38 that’s now in my SE5A 

whilst it’s ok ish I would like to try something different 

[cymaz]

Feeling  flush ?

[bert baker]

It’s a possibility 

have noted the low rpm

 

the different array of fuel mixes on the petrol four strokes is a bit of a worry  
 

 

[bert baker]

Back to the grindstone 

time to get some balsa bashing done 

 

 

[bert baker]

Slowly slowly 

[Paul De Tourtoulon]

"Bashing", maybe an axe would do a cleaner job than your claw hammer,,,

[bert baker]

All ready to cover,
Although ow would have been better if I could get 1.2M of Solartex Satin Cub Yellow 

 

I've primed it with some Cover Grip

Be interesting to see how it compares to Balsaloc 

 

Ive ordered the paint 

[cymaz]

I’m now leaning towards using nylon and dope. Easy to apply once the proper preparation has been done. Paint adheres well to it and it stays very tight.

[bert baker]

I’m thinking on the same lines but trying Diatex 100

 

[bert baker]

Finally got the wings Re covered since a rebuild of my Premier Tiger-moth,

mot was me who purchased all the Silver Solartex in the land

 

[bert baker]

Next up is to fire up the CNC router and cut some ribs for the rebuild of the Green and Silver Stampe,

Hopefully the cut files will still be on the computer since curt some for Williams Blue Stampe so should be fairly straight forward
