Anyone build Uravitch's 81" Bronco? Nearly completed and it's coming in about 12 lbs. or so. What engines are you using?

Hi, I am about to start on mine....I measured the plans and I believe .91 OS FX's will fit if you don't use the wooden block offset on the firewall...THey may protrude out of the top though...just a little....Mr lumpkin aka TWIN MAN says to go large like a .61 and up if you fly off grass besides you can throttle back...I am still debating myself...

ACHTUNG!!! Caution!!!! I remembered that you'd better reinforce the horizontal stab/elevator mounts as 3 seperate people had elevators fly off in flight.... Just a warning..

There is a post nearby that I started several months ago about my Dad's OV-10.

12 lbs is really light. Ours is closer to 20 (for a number of reasons - including a pound of ballast in the nose ) and 2 saito 91's provide plenty of power.

It is a sweet flyer!

My ears are burning. Yes, if the plane is over twelve pounds and you fly off of grass, I would suggest at least 90's.
Mine at rcwarbirds.com is a little heavier and I wanted scale three blade props, so it has a "Little" larger engines.
Good Luck,

I scratch built a 70 inch version. Mine is about 13lbs I'm not sure always been to scareed to weigh it!! I first flew it off of grass with a pair of MDS.40's It was scarey a little low on power no room for mistakes. I went to a pair of Thunder Tiger .61's and made a fun airplane to fly. I mistake I made was not putting flaps on it, landing speeds are very high. We have about 900 foot of very nice grass runway and it takes most of it to land! Live and learn high wing loaded airplanes need flaps!

I have both nacelles framed up and the fuse framed on mine. I wasnt going to put flaps on, but now I think I will. Still havent chose what retract to use. I've been shopping, found some scale looking retracts, but $$$. But I like em!.....Don't tell anyone, but I ran nyrod thru the fins for the elevators..... Then I read to beef up the stab area...... so I chose to drill a few holes and glue 1/8 inch dowels thru the stab and plywood nacelle sides......Yup you guessed it. Shhhhhh.... I drilled right through the nyrod caseing on both sides. Put a dowel right through em' both...duh
Actually, my repair job made things a little smoother, and I believe stronger.
This is a cool looking plane, I can't wait for the first high speed low pass........

I will not tell you know sometimes things just happen! I have alway felt it usaully was for the better. I think you will like having flaps. I took off work Friday it going to be nice here and hope to get a few more flights on the OV-10. I will try to get a picture to post.

I build mine the cheap way, we fly off a grass field I did fixed gear. I also do not have cowling on this one. I had a small one with MDS .28s on it and the overheated with the cowls. The way the fire wall is on the OV-10 you need to duct the hot air out some way, mine did not have enough exit area. I fixed it the easy way on the bigger one I left the cowls off. Yea I know it does not look right but it sure is fun to fly!!!

It is modeled after one NASA still uses for atmospheric research.

Nony, What kind of engines did you use? Do you have trouble keeping them cool?
