Official Nexa OV-10 Bronco 1800mm ARF Discussion Thread

I found the manual's recommended CG to be spot on...

[MikeT]

About ready to wrap up my assembly. Any of you that have flown this have any thoughts on CG , flap to elevator mix or any other helpful tips?

Thanks

Just finished hooking up my two receiver's, one in each fuse. So now putting together at the field I only have ESC to battery out of one wing and the same on the other wing plus nose gear lead.
Hopefully it looks like it all works well...………….well till the test flight. Still waiting for MRC to get the retracts in, got to be soon, surely

[TBolt]

I'm going with a separate receiver battery.

Hi Guys
The build continues, I am thinking of running two Rx's one in each fuse it would be easier at the field when putting it together, less connections and no cutting of red wire on ESC. ( thanks Wrangler1 )
This seems like a good idea to me. but I've been wrong before ( 1972 ) Could I have your thoughts on this pro's and con's

I did that in the old LX P-38 and it worked great.

Unless you have the capability to handle 2 receivers at the same time that are synchronized together, i never done that. So i can't help you there. Although it will be interesting to see how that works and what measures (if you think on those) will you take if something happens to one of the Esc internal Becs that affect the Receiver. Also i will suggest to add a capacitor to the receiver so when the engine starts (if it is electric) the amp draw does not affect the rx. i will post a photo of the one i'm using.

Fits it pretty well i say! Nice.

Just a tad larger than I would have liked but I don't think anyone will notice or even care.

Used some of Callie's graphics but decided to go with Motions A-10 Shark Teeth. The water slide with setting solution is a bit easier to work with.

Thanks Wrangler1, was concerned about the current draw through the wires and connectors.
Next question is with two ESC's you have to cut out one of the red wires ( instruction manual page 43 ) I'm not sure why this is !!!

Is used in case you decide to use the ESC integrated BEC. So the receiver is connected to only one power supply. Is a common practice, but in my case due to the aircraft size and the time that i'm spending on it i choose to go with a separate power supply. A 2,500mah 3 cell Life attached to a 20amp Bec (was the one i have available). So in case something happens with the motor batteries i still have control.

After reading through the thread I thought this looks good, so ordered one.
Received big box and recommended servo's only to find the recommended servo's were standard size...…..wrong, should be micro ( they have changed web page now )
After a seniors moment I found some 5S battery's at HK. so now going with eflite power 46 and 100 amp ESC.
Question: When hooking up power do you Y lead the ESC's and Y lead the two battery's or is it one battery to one ESC ?
Well it's now a matter of waiting for the retracts to arrive at MRC, can't be much longer, surely.

In my case i will do 2 options, a " y " extension to be used with one 6s 6500, and in case i decide to use two 6s 5000mah i will connect them directly to the ESC'S.

Apparently there were 2 both now retired from I understand.

I think the NASA OV-10s were both recalled and used in the 2015 mid east OV-10 experiment.
They are likely two of the four the US is selling off. https://www.thedrive.com/the-war-zon...being-sold-off

Outstanding find Mike..........in all the years of perusing the WWW I have never come across the NASA Bronco

Crap wish I had these pictures before I started mine.

Hello to all, i resume the building of the plane and at the moment i just install the nose gear cover. I needed to order a new cover since i broke the one that came with the plane.
On the power setup, i plan to fly it on 6S 5000 .

You can't put full figure pilots in it. The front pilot is above the front retract and steering servo. The rear is above the lipos. You could put the lipos further back in the fuselage but the nose would have to have a large amount of weight for proper CG. As I have said before, you can use a 4s set-up but for me it wasn't enough oomph. I tried different prop combos but none seemed like it was enough for my style of flying. I'm using the 5s set-up with HRB lipos. They aren't that expensive and have worked well for me in many applications. I have a VQ Beechcraft Bonanza with an E-Flite 46 using the same 5 cell lipos that I'm using for the Bronco so I have more than one plane on 5s.
