	Sweet! I don't think you'll have any worries about control response. You definitely do not want anything more than enough to be able to keep it within the confines of your flying patch - the wing won't take too much of the G force from a sharp turn or pull-out, unless you swapped out the spars for spruce.

	WoW...sweet looking model. With the twin vertical stabs you can get away with that light mono-gear. I like the scheme!

	It's been a rough week, maybe things are back to a normal roar....I think we are finished with this little jewel. Maiden flight when it is warmer and no wind....

	Looks great and the perfect location for the battery. This will be a great flyer!

	Progress, got the tail feathers on, and the elevator hooked up, then I decided to do the front bottom 'bubble'...it's a design feature...so it will be useful in holding the small battery! Using 1/64" sheeting here...

	The wing is built, slowly putting the covering on....tissue wrapping paper. This stuff is tuffer than tissue, a little heavier tho. I have the RC gear bound to my new transmitter, and this motor is DEFINITELY strong enough ....will blow papers off my table!!! Marc

	Wing time...Volare kits are really nice, great prices too for poor old farts like me! I'll spend some time this morning inside at my building board...after lunch, when it dries up outside...I have some painting to do....you know, "fall work to get done before winter" stuff....we all do it

	Ditto what Ian said!!! Twin verticals are great and the Connie's triple even better!

	I like the look of anything with twin rudders, even the Ercoupe! I think that they fly better for some reason. Keep up the good work! ian

	I have the tail stuff going pretty good....I will hav the rudder linked to a cross bar, so both rudders operate at the same tim. You can see my pivot point mounts, which I will use a 90degree servo arm linked up. The elevator is a little more easy, the pushrod will exit straight out the bottom. It's neat to engineer stuff, and try to keep it light! Marc

	doubling the 1/16" sides really beefs up the fuselage!!! Looking good! Sky9pilot

	When you want to try your patience in building a small straight fuselage.....build one of these ....cuss jar is overflowing now...but it's done. It's the double curves that are hard, the only flat place is the wing saddle. Anyways, I decided to mount the motor. When she dries, I'll mount the servo brick....20.9gms with radio and motor....

	The sides are being attached at one station at a time....the fuse has curves in all directions soooo she's kinda tricky, I'm trying not to build it a third time...

	Progress....the sides and top/bottom are built using 1/16" with trusses. Small weight penalty for strength! Motor mount and servo brick mounts being made. I will expect her to be very light. The motor and batt, servo brick may be the only weight here...I haven't weight them, but I'd say 10gm. We will let all the titbond glue to dry good, then after lunch, I'll do the port side and glue up. Then on station pull together and glue. Next time, I will get 2rulers to lay on the sides that are exactly parallel seems, I thought I was on the plan...then when dry, she has a tiny sway...maybe a .5mm deviation....not noticeable but not perfect either Human error.......
