Any body got any suggestions about building one of these models? I am hoping to get one soon and would like some thoughts and suggestions about it.. I'm Obliged ... H^^ D>K

They are nice planes! I have seen a couple of examples. One was really gorgeous.
The plans call out a special tank with only two lines. If you read the construction article, it explains exactly how to deal with that, and it makes perfect sense. I just built one for a friend.
Pick an engine you are sure will be a steady runner, because you won't want to lose this one if the engine dies in the wrong place. A Medallion would be good if the plane was light.
As on most half-A's, watch the weight. Since this one is designed like a big stunter, if you don't keep your thinking in line with the scale of this plane, it will end up heavy.
I have a Pinto kit that someday should get assembled. Got to finish up some of the other partially assembled nightmares filling up the shop right now....
Go for it!

Thanks Dave, I have a Medallion and hope to get the model finished at 10-12 oz ready to fly (dry weight) what are your goals on your pinto, and thanks for the advice.. D>K #^

I have a Pinto that flies well with a Medallion .049 for power. Like Dave said the key is keeping it light.
Mine weighs 9 1/2 ounces completed and I used Coverlite on the wing and stabilizer. Prop is a COX 5 1/2 X 3.

I have another question, what size lines and type (steel or other) and length? Again thanks.. #^ n~ :!
-
With a Medallion and 6-3 pro, I would try 38’ x .008” lines and handle spacing about 1.25x 1 to your bellcrank size. Be afraid. Be very afraid and ready to adjust everything. Half A model setups just are not well established like the ones for big models. It takes a lot of flying to get one just right. But when you do get it right they can fly as well as the big ones.
-
H^^ again thanks.. I see that on the plans a 2" B/C was used, what other size would y'all use? Again thanks
-
I'd use the 2" bellcrank but pair it with a handle spacing of around 1-1/2". That seems to be the zone I'm comfortable with. (The Renger/RSM handle has adjustable spacing, and also has some overhang which helps center things a bit, too.) I use that combination on most everything to start with--and mostly don't find a need to change it.
Larry may worry about the control ratios on his planes a lot and he should--he flies stuff like Fright Streaks and such. I, on the other hand, only fly normal stuff like the DARPA RotorWing, which used my standard control setup....

A few years back I built a Pinto with a TD.051. It had a homemade tank. I flew it on 40' x.008 lines. Handle spacing was about 2". It was the best flying 1/2A model I'd ever flown. I didn't use the motor beams for engine mounting as I wanted the room in the the nose for my tank.I used a fiber filled radial mount. Build the plane ,you won't be disappointed.....Skip

Would a Pinto be all right with a Norvel .061 Big Mig? The motor I have on hand has a lot of scat thanks to Rockin' Rusty's great break-in directions. Maybe a Tercel also?

Medallion .049 flown on45 foot .008 lines. Flies very well.
-
Sweet! Looks gorgeous! 👍
What does it weigh, what size tank? Full pattern? We need details on this gem. Finish? Prop, fuel, the whole maguilla.
There is way too little information on how to get a 1/2A stunter working right. We need to share more than a tempting photo.

Here I am with my Pinto....still have the remains!

Just received the plans for it from AMA $8.00 plus $5.00 shipping. Will take to work and scan in and make a pdf.
