Status: offline 		Given I'd probably opt for the electric power in the Tri-Squire I'll be building, I would most likely go for smaller servo to save some weight; though I would not use the tiny servos for this plane. The idea of electric power appeals to me vs. a 4S, initially considered, because the airframe will remain clean. Thanks for the info.

I agree on building light, but this is one where the difference of an ounce will have no ill effect since so much weight has been shed already.

I originally built this in 1978 (yipes! 30 years ago...) while in college. I always got hung up on installing the systems. I guess ACS_guitars and Rainedave have shamed me.

I got back into RC flying a couple of years ago and knocked out a mess of ARFs. As such, I've been installing systems without a hitch. One day I looked in my closet and thought "geez, my TriSquire looks sort of like an ARF..." Anyhoo, my 10 year old son asked me "why don't we get that flying?" Of course I had no good reason to say no so it's on the workbench as we speak.

I plan on putting a slimer on it just because it seems like that was my plan for the last 30 years. Here is the project after we dusted it off. I've got an engine and tank and will be getting back on it. Gotta get a flight pack on order.

Hey, what nose gear did you guys use? I'd like to make this one steerable.

Your birds look great. I'll try to keep up with progress pictures also. I tried to attach some photos. Not sure if those took.

Status: offline 		Pro, have you ever used fixed nose gear? I had it on my Goldberg Skylark and really liked it. It steers on grass very well. Just hold up elevator and steer with the rudder. It never loosens or gets out of whack and it can't strip your rudder servo, so you can use all micro servos.

If you have a paved runway, different story.

My plans are buried somewhere and I don't have ready access for the dihedral measurement. Yes, I am using the small cord elevator and at first I had reservations about it. However, after flying it, it is plenty.

Status: offline 		Hi, jjscott!

Checked my plans and the dihedral is shown as 3 1/4 inch on each wing tip. Or..lay one wing panel flat to the building board and raise the other 6 1/2 inches. Works the same. Hope this helps and happy building.

Joe

Edit: This 3 1/4" measurement on my plan is shown from the flat table/ building board surface to the top of the wing tip surface.

Status: online 		Thanks guys. I'm drawing plans by enlarging the jpgs at the beginning of this topic. I cropped then printed them out on 8 1/2 x 11. Then I scale up the drawing to size using known dimensions. It's actually working quite well at least what I've got looks like a Tri-Squire even though I may be off a bit dimensionally here and there. I couldn't read the dihedral dimension on the jpg.
