micro biplan 2

this is my first micro biplan.
i found the plan in rtp micro plane michael thread(pink panther)
so nice that i dedided to make it rc.
i used 3 mm depron and 2 mm selitac for wings(curved on a rolling spin heated in the kitchen oven,while my wife was in the garden!)
span= 25 cm,6 mm, 4.5 ohms pager,red= 1/7,10cm carbon 0.3 gr carbon prop(ff blue one copy)
90 ma lipoly,coural combo,12/13 gr auw.
i'll first try ailerons on lower wing with 1.5 gr stong double arm actuator+ 0.5 gr elevator one.
wonder if it's not too "lazy" on roll?
with 10 gr static thrust i think it'll be nervous!
this is the first pic!
patrick.

Or Pepe le Pew! And Patrick could design some horrible smell to go with it

PS: That Selitac looks familiar

I noticed you mounted your prop on the wrong side of the plane.. the tork is going tobe worse on that side. you should if possible remount on the right side... hope she ROG's good for ya!

It should be fine on that side. Just put some ballast on the right wing tip. I fly my 10" guided mite with prop on the left side but it is a smaller prop. looks like you have plenty vertical area to counteract the torque as well. Now when you get down to 3" planes the torque rolling does become a problem but can be overcome.

Nice plane by the way.

Pepe le Pew is a skunk with a heavy French accent. If you scroll down to the bottom of these pages there are some sound bites:

Patric ,
I think you have the motor on the correct side the offset thrust line has the same effect as adding right thrust.

sorry michael but my connection have no fragrance channel!!maybe in the future!
dave: ok for a snoopy with a long scarf flutting in the wind!
but it's not yet finished.
finally i think to use one bird 0.5 gr actuator for each aileron on the lower wing.
very good article in rcmicroflight this month about biplanes construction.
patrick.
