Bob Banka (Scale Model Research) has nine or ten photo paks of Ov-10 in several schemes. Oh, you WILL come out tail-heavy; get the biggest battery pack you can get in the nose, mine's done except for finishing the wing, I did a test balance and ordered ANOTHER 1800 pack to parallel the first one; get out the hole-saw and swiss-cheese the rear end of the nacelle sides; make sure wood for elevator is dead light-the rest of the tail needs all the strength you can get. I have pix of my stab mounts, as soon as I can figure out how to post them on this *&^%$#@#MACHINE FROM HELL! I'm using two O.S. .70 four strokes with three blade 11 or 12-7 props.

I used a 36"x80" closet door on saw horses and built both wings and the tail parts at once.

Bob Bamka (Scale Model Research) has lots of photo packs of Bronco variants, some have panel/ejection seat views.

Hello all. FYI, I emailed Dan Palmer and asked him if he could give me a few names of people that had built a Bronco from his plans. He replied back promptly that he did not have any names he could give me, and suggested I check out the chat rooms and forums for that information. I then replied and asked him if he could answer a few basic questions, such as had he sold a lot of plans, are they still "ever popular" as he advertises on his website, and did he build a prototype of the model or had he seen a model built from his plans fly, and if so were there any problems, how did it fly, etc. He did not reply back....you can draw your own conclusions from that. Although I was hoping for something a little bigger, I am going to build the RU 81" version. For those that are interested, I contacted American Eagle Model Aircraft, web site: www.flyrcmodels.com and they have a kit that includes plans, fiberglass booms and pod, and foam wing core for what I consider a very reasonable price, considering the consruction time that will be saved. Have any of you bought or seen this kit? If so, what was your opinion of it.

Speaking of useful weight and large battery sets, I needed nose weight in my UltraStick 120, it got a set of Sanyo KR4400D cells - 4.4 amp hour capacity. If I kill my car battery charging the electrics I use the plane to jump the car. Well, maybe a slight exaggeration, but not much.

I also have the Ultravich 80" plans
I notice in the thread there are notes about the tail and NOT using the bellcranks

Anybody got some pics and further details to explain this
Also noted someone saying they had a fiberglass vs. balsa - any info on that one as well

Here is a shot of the tail of my Bronco. You can see the servo mounted in the fin. There are servos in both fins. Low profile servos fit well in the fiberglass fins.

Here is a shot of the first takeoff. Two ST 90's running very rich had no problem hauling the 21lbs into the air. Flaps were used on takeoff because the inadequate 3/16 wire gear flexed and bent so badly it was difficult to get it to rotate. New gear to be installed.
Those trees are not nearly as close as the telephoto lens makes them look.

I will start my 81" Bronco this winter. The plan is for 2 x Saito 72s. The first engine has about 4 hours in an Extra (60 size) and has been rock solid. I'll drop the 2nd Saito 72 in the same plane for break-in shortly. They weigh about 50 grams less then the 91s and are rated at 1.2 vs 1.6 hp.
JHM has an 'on-board glow driver' I plan to use. Have used it on another setup and they help even poor performing engines run better.
This thread is excellent! Got me fired up to get on the stick and get mine going.

I was wondering the same thing as Crashnburn:

Has anyone built the American Eagle short kit of the OV-10? What did you think of it? At $350 for the short kit and $420 for the Sierra scale landing gear, you could have a contest quality Bronco for less than the cost of a VQ P-38.

Thanks,

Jay

Check your math on VQ. Holiday special at http://www.vqmodelaircraft.com/produ...craft/p38.html is $600. No more Morris hobbies.
Unfortunately my 84" Bronco is no more!!!! Whine whine

Hi Guys,

I would be extremely grateful for any information and photo's of your engine installations in the 81" Bronco. I am trying to figure out the best way of fitting the two OS61's without having anything stick out, head or muffler etc.

Many thanks,

Sarah

Looks like I read the fish weighing scale wrong..it came in at 21 lbs. (not 12) with 1 1/2 lbs. of lead in the nose. Two OS .61FX with 13/6 props at 10300 rpm. Take a look at how I store the plane and the easy way to transport to the flying field without taking the tail feathers apart each time.

Hey Twinman, and all you "carpenters" out there...
I just ordered the new 81" Bronco ARF from Hobby Hangar along with the Spring Air gear made for it (Sierra Precision not ready yet) and a dbalsa.com scale cockpit ( to be shipped next week).
Going to power it with Saito 72's or T.T. 61's, undecided.
The bird is silver grey with a white bottom and red wing tips.
Cost is $429.00 for the plane and $125.00 for the cockpit.
Don't know how much the gear is, forgot to ask when I made the second phone call to add the gear to my order the next day.

Twins make yor crazy?

Hi Carlos Murphy,
When you get your ARF, let us know what you think of it. I have been thinking of doing the same.
Was in Nam in 68 and always looked up when one of these birds went over. I sat in a real OV10 while at the Chu Lai air base. Couldn't get over how high you sit in the cockpit...all un-protected by plexeglass.

MX240,

Semper Fi, Bud! I was in MAG11 at Da Nang '70 - '71. VMO-2 was just a few hangars down from us and, like you, I loved watching these birds. Late in '70, the squadron started strapping cannon under the fuselage centerline of a few of their birds. Big, big guns! The conical flash suppressor was just inches behind the front strut and the breech was about eight feet behind that. Rumor mill had it that they were 37 - 40mm auto loading weapons. Lord only knows where they got them. From what I heard, the tech reps had fits as the OV-10 was never designed for the stress these guns would impart along the fuselage bottom where these cannon were now attached. Shortly after the addition of the heavy firepower, stenciled "gook heads" started appearing on the sides of the Broncos. Guess the cannon worked! I've never seen a picture of a Bronco with this modification but it was impressive, to say the least.

Take care, MX. See you in Hell!

Musta mist it, where do I get the glass parts for the 81"er.

I canceled the ARF from Hobby Hangar, found one built from scratch and didn't have to wait for it. May get one at a later date.

Twinman,
Which mufflers did you use on your 148's?

Just a crazy question, has anyone installed functional retract gear doors on their OV-10?

flyalan

My Feedback: (47)

I have been working on mine for about a year or so off and on. Mostly off...

Using Century Jet retracts (semi-scale), cockpit kit from Dbalsa, In-cowl mufflers (actually behind firewall), and Kimbrough rotary drive for ailerons.

Using 6 servos in wing(4-flap, 2 aileron), 3 servos in each nacelle(rudder and throttle) and 1 in nose for steering and of course 1 for retracts.

Using thin wing servo's in the horizontal stab x 2 for the Elevator (wires run up the vertical stab).

SuperTiger G-75's for power.

Have posted a few pics of the construction and also a collection of actual OV-10 pics that I have taken and/or collected for this project.

My paint scheme will be that of VAL-4, Naval Light Attack Squadron (Black Ponies).

The Pics may be viewed at:

The construction photos are on page 10.

Cheers....
