I know not everyone agrees about weight, but I have NEVER regretted lightening up an airplane, and I fly in as much wind as anyone in the club. For me, given how cheap mini and micro servos are now, this would be a really easy choice.

I flew my Tri-Squire in 1971 with KPS-9 servos

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.

Well, you guys got me motivated. After moving this project halfway across the country three times I figure it's time to finish it. 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.

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.

Here are pictures of mine, hot off the press. I am not sure what the nose wheel bracket is, but I want to say GoldBerg with 1/8 inch wire.

What do the plans show as dihedral in the wing? And, has everyone continued to use what looks to be a very small chord elevator? You all are doing great jobs on your planes.

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.

Ireally enjoy seeing the old stuff. It surely brings back some neat old memories.On the back burner is my want to build a "champ"My Buddie flew one for years on floats. thanks for the trip back.

The plans show 2 1/8" from reference surface to bottom of wing tip. Hope this helps!

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.

jjscott

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.

I had an OS 19 on my Tri-Squire in 1971 and I used to hand launch it.

It's ALIVE!!! Ha! Good to see I have inspired so many with this one! Mine is still waiting to be covered. I have the Thermalspan and the dope, but no time. I will be moving to Jacksonville, FL with in the next 2 months, so I don't think I'll have it done until fall, but in Florida, flying season NEVER ends!! I am really looking forward to the move, hopefully I can get my fleet to the new house with out any damage. Keep on building! This is a mostly forgotten classic it seems as the Esquire was the more popular out of the old Midwest line-up.

Hi Acs guitars! Got all my formers cut out and the rear ones glued together on my Tri-Squire being built from those plans you sent me. What fun building my first R/C plane again from the early seventies. Will be putting glue to the fuselage real soon. As a sign of the times...I ran around last week to the LHS to pick up some 3/8" X 1/2" maple for the motor mount...the LHS doesn't carry such items anymore. I'll have to make a stop at a cabinet shop or the like in order to get the maple wood! Who'd a thought....

Good luck on your move to Florida! I lived down there in the early '90's in Melbourne. Yep..you CAN fly all the time but let me tell you son..it gets HOT! down there during the day. I did most of my flying in the early morning (6 to 9 AM) or later in the evening (7 to 9 PM). And you'll find yourself staying away from dark color schemes too 'cause those planes look real funny-like when they puff up....

Not so worried about the heat... Here in Oklahoma we regularly see temps around 100F in the summer and have a heat index of 110F+ with high humidity and ZERO wind (hard to breathe). In Jax I should see highs of 95 most summer days and living close to the beach I expect a nice breeze. Glad to hear the plane is coming together! Good luck and keep us updated!

How is everyone coming on the Ti-squire builds? I am getting really anxious to get mine covered and in the air. Still just to busy getting ready for the move [:@]

Hi, Acs! Have most of the parts cut out for my Tri-Squire and will be putting glue to balsa. This has been a lot of fun so far!!

Hope all goes well with your move. Soft landings. Joe

Hi, Those pictures bring back good memories, My first successful R/C airplane was a Midwest Tri Squire that I built in 1968. It had a K&B Veco .19 R/C engine and a Controlaire 2-3-4 radio with only 2 servoes to start with. The old fella at the hobby shop reccommended using only throttle and rudder to start with and then add more controls later, which I did. I learned to fly without any assistance with this airplane, and it was deffinatly a good choice!! The attached photo is just before the maiden flight in 68, note the snow!!! Good circulation back in those days I guess!!

Finally getting back to RCU and glad to see there is still interest in the TriSquire.... My last post was on 6-24-08, the next day I recieved a call and got news that my father in-law in Jaksonville had passed away. So to say the least, this has been a rocky 6 months. The move to FL got pushed back to September, and RC went on hold. If it weren't for the Parkzone micros I would not have had a chance to fly at all. All of my building projects are on hold until I complete the building of my new workshop. The TriSquire made the 1200 mile treck with out so much as a dent, and I am still really anxious to get it along with 2 or 3 other built planes in the air by this spring.

Nice work guys.

We expect both of you bring your Tri-sqires to the VRCS DeBolt Vintage Reunion on Mar 14, 15, 2009.
To be held at Dunellon FL.
You will be well received.

If I can get this thing covered and flight trimmed by March I'll be there.

I'm interested in the plans for the Tri-Squire.  That was my first RC airplane back in 1966.  If you can send them to me, I'll be glad to provide an email address.
