OV-10 for GWS EPS Drives

I have a CAD model half completed for a fan-fold OV-10 Bronco. Plan is to power it with twin GWS EPS geared drives, 2 GWS 7 cell NiMH batteries, 2 ICS300 speed controllers, and aileron, rudder, elevator, and retracts (robart 1/2a). Maybe flaps, but I dont think they will be necessary. May nix retracts if weight gets too high, but I cant believe that will happen.

Wingspan now is 37" or so, planning to use fan fold for a formed airfoil wing also.

What do you guys think? I will post some pictures as soon as I have something good to show...I think it will make an awesome park twin.

So do I, sounds like a great project. Some of the guys have done Broncos in the past and they are nice planes.

Sounds great Ben. There's probably more than a few of us who'd like to piggyback on your development effort and do one of our own.

I've planning on doing a Bronco for some time now. I've got three sets of plans and one balsa kit (K&A) that I've been waiting to build. I'm specifically waiting for my RC piloting skills to catch up with my building/flying ambitions, I'm new to RC. I flew the real Bronco for a few tours back in the 80s. Let me know if you need any more specs, drawings, photos, or tech manual information, I've got a Bronco library.

Cheers,
Todd

Thanks for the offer! I may take you up on it.

I really like the idea of this project because the GWS drive units are cheap, and I think I could fly this at my local high school field.

I have the fuse and boom profiles in solidworks CAD now, as well as EPS drive units modeled. There will obviously be compromises in order to make it relatively simple in fan-fold foam, but I think it will look really sharp. I hope to do some work on it tonight, maybe I will post some pics then. Thanks,

Ben

I will post the templates as I go so that you guys can build one at the same time, if you want. I cant guarantee how it will fly, but maybe if we wrap our collective heads around it, it will turn out better!

Here is the CAD for the fuselage. You can see the robart 1/2a nose gear and the 2 GWS drives modeled.

Few more nights like tonight and I will be cutting in no time!

I can send files to anyone who might be interested in trying to make one. Keep in mind that it is experimental at this point..(i.e. it may not fly very well!)

You guys beat me to it... I wanted to do exactly this same thing one day. Every FFF plane I make, I think "I oughta do a GWS Bronco...) Woohoo, here it comes!! What are the pointy things at the back of the tailbooms though?

BTW if you need some scale reference, check out the website I do on the side: www.OV-10Bronco.Net I have a bunch of stuff I haven't posted so if you're looking for specific info or photos lemme know too and I'll see what I can do.

Todd-
What unit did you serve in? Check out our website and get in touch with us... everyone's welcome in the Bronco Assn. but crew members especially so... it's a good fun group (a lot like the EZone, but with a museum and a 100% scale OV-10 model)

Broncos Forever!

Hmmm... as far as we know there are no flying OV-10s in the USA that aren't owned by NASA, the Calif. Dept. of Forestry and Fire, or the US State Dept... there are several in museums, including one in North Carolina... any idea who this might be? (It could be an O-2 or an OV-1 that you're thinking of.. or the white NASA plane N524NA, which is a really beautiful aircraft.)
