More on 40/60/90 Pattern

[Tomanek, Wojtek]

Use scaled down wings from sequel or prophecy.  Typhoon wings are too big.
Or get one of the new pattern type ARFs.

	   Hi everyone, greetings from Chile!
	   
	   I want to move on to "advanced" pattern. (Here in Chile we only
	fly novice, advanced and F3A) 
	   I'd like to build a nice plane for my Saito72. (I don't want to
	get a .91 engine, I'll wait more and get a Webra145 for a 2m plane
	later)

	   So, I have an engine that pulls more than my former 46FX but less
	than a 90. I think the available 40 size models are too small and
the
	60/90 too big. Here's my idea:


	  I'll take the typhoon 2000 plans, reduce them to 77% (60.5",
	694sq.in.) and use an eppler 168 airfoil on the wing (1-piece, of
	course). For the landing gear, I'd use fixed aluminium gear on the
	fuse. Dry-weight should be under 2.5kg (5.5lb).


	  Questions:

	         - Does it sound good?? (Or at least would work better than
a
	Tracer46, Venus, Spectrum or Tai-ji.40??)

	         - I'd build the tail group flat. Any suggestions for
	airfoils on the stabs? Would I get any clear benneffits on an
	airplane this size?

	         - Would retracts work better? There's a lot of weight
there!
	    

	      Thanks a lot for your comments/suggestions!!!
