Hi Sunnyside,

Looks like an interesting project. Just a suggestion, providing some commentary will be helpful for others to appreciate better what you are doing. I would like to know more about your ideas for this project. Cheers.

Will try. Thanks!

The engine was mounted to the bench and ran-in for more than a gallon of fuel.

I have decided to oriented the engine mount such that the manifold and muffler results in a 6 o'clock direction.

The landing gear is made from aluminium flat bar, bent to shape. A 3mm wire tensioner was necessary as the flex on the aluminium bar was excessive. The position of the tension wire was later found to be less than ideal.

The wheels in the photo are temporary fitting, the actual wheels are larger in diameter.

What are you using to build the fuselage. It looks like some kind of PVC like material - could be wrong. I like you running in bench With most of the current crop of high quality engines, one needs only to fly rich and refrain from extended full throttle runs for the first gallon and they'll be fine.

Hey sunnyside

i saw a similar plane flew at CDF a while back was that this plane?

sunnyside, just some curious questions:

Where did you get those white rectangular pieces from? Or what is it, anyway? The SPAD site usually recommends some "gutter pipe" that most hardware shops here don't know what it is.

How do you stick the coroplast to the white material? Epoxy usually doesn't work so well because it doesn't soak into the coroplast.

The fuse is a combination of corrugated plastic sheet available from Art Friend and the White material, something I found in the refuse bin at an industrial area behind Safra Tampines.

Bench run-in of new engines has many benefits. The one I like most is "if you can't getting right on the ground, it's not gonna get better in the air" .

It is not similar. That is the plane.

Gutter pipe (American or Canadian) = Air-con trunking (Singapore)

The one in the picture is something I picked up from trash.

Sand both surfaces. I used PVC adhesive and Max Bond and CA for tacking.

The other method is CA + water mist. This I used on the wings.
