Aresti 40

[Larry Diamond]

Any idea on weight?

I had (Ooops, lawn dart) a 8 year old GP Trainer-40 with a 46 on it and did
very good and has more drag than the A-40. Vertical could have been
improved. The plane was exactly 6 lbs.

My dilemma is the engine size for the A-40. I have the 46, it survived, and
was going to use it. The specs call out 4-1/2 to 6 lbs, a very wide window.
If it comes in at 6 lbs, I would consider a 60. At 5-1/2 lbs I would use the
46. Don't have any experience with the 60 to know if it's too much weight
and overkill on power. A-40 seems pretty small for a OS 61 FX though.

If anyone has good experience with the MDS engines, I would bite the bullet
an go with a MDS 58...Don't know anything about MDS, but the price is
right...

There's a great article in the latest issue of Flying Models on the 'A - 40'
(also has a nice front cover photo of it, too). The author used a Saito 72
and
liked the combo. To me, a 40 size engine would seem a stretch for power

I had thought about using my Saito 56 in the A-40 I am building but was it
was
suggested it might be a little weak in the verticals, so have opted for a
ringed
OS 50SX and use good throttle control (one doesn't always have to fly fast
<G>).

The (Flying Models) article indicates (as did a good friend) that it  pulled
a
little to
the canopy in verticals and required some forward stick pressure while
inverted,
but other than
this nothing else (e.g. weight) was much of a concern. The magazine article
outlines
the adjustments made.

I'm looking forward to flying mine. Good luck with yours...
