OK, have the steering servos placed and the retract shim blocks in. The servos are HS65MG with 30 in/oz and since ill be using an arm connection shorter than 1", i should have over 55in/oz of torque from EACH servo on the steering. I placed a 1/8"ply mounting plate and made the opening in the existing frame big enough that the servo sits recessed. I plan to use a Dubro micro pull-pull kit but need to figure a suitable connection on the steering yoke that will allow the cable to go slack and not catch on any structure when the gear extends.

Originally posted by sam51401 View PostWrangler, have you setup the Frsky Sbus yet? If I run life pack for 6.6v and y the two Sbus on the receiver, do know if the receiver bus can handle 7 servos on one port? I’m trying to find Sbus ref on the RCG thread but not found much yet on Sbus limits or suggestions.

I inquired to Aloft Hobbies on FrSky SBus capabilties as i was concerned about running seven servos from one receiver port. My question and the reply from Wayne at Aloft.7 HS225 servos will probably be fine, I suspect that would only pull a couple of amps at max. If you are pulling more than 8 amps I would start looking at running seperate power lines direct to the decoders to help avoid all of the power going through a single servo connector.Like to hear what the load and servo count limits would be on a X8R using Sbus with two 4 servo decoders Y'd off the SBus port. Battery will be 6.6v LiFe and all servos will be HS225MG. It is a twin OV-10 Bronco that I plan to use a dual SBus for primary flight controls connected as such,
2 Aileron, 2 Flap, 2 Rudder 1 Elevator on two SBus decoders. Left SBus is A,F,R and E while the other will be A,F,R. Ailerons will be seperate channels but Ruddder and Flaps will be same channel over both SBus decoders. Electric gear gear will have seperate power input so not using receiver power bus.
Might want to double check the amp load, but think you will be fine.
How would you rate my reply?
Great Okay Not Good

The Bronco used the M60C variant which had a standard 7.62mm ( .308 inch) bore diameter whereas the C model had a gas evacuator/ barrel extension system which was approx. 2.5 times the bore which was used on heli gunships and the OV-10. I would go with a outer barrel diameter of 20mm (3/4inch) which scales to like a 3mm brass tube.

I decided to change my factory livery to the Black Ponies of Val 4, Vietnam period. I got the idea off a Squadron Publications Cover. Callie did the graphics package, great job. The plane has 2 Rimfire .60's, with 100 amp esc's. The motors are good to 62 amps constant draw. I probably will use counter rotating 12 x 8, 2 blades. and 13 x8 3 blade props if draw is under the 62 amp level. Power comes from 2 x 6 cell 5000 ma lipo packs , and a 2s lipo battery pack for radio, and servos. I have saved at least 2 planes by having a power pack,separate from the esc power circuit. Personal preference...... Have not balanced the plane yet, but that is next. It has been a fun project.. We need to build a fire under everyone that bought this plane, and have them share there experiences with the gang.

I flew the Bronco today with a 5s set-up. What a difference from the 4s I tried. The 5s set-up will remain for now. Since the 5 cell lipos are heavier than the 4 cell, I will be able to take out weight in the nose. I am using E-flite power 32s, 100 amp ESCs, and 11x7 MAS three bladed props. This combo pulls 42 amps per motor at full throttle. I expect to get about 7 to 8 minutes of flight with a 5000 mah 5s lipo. I can fly it at half throttle and still have enough reserve power. With the 4 cell set-up I just didn't feel it had enough oomph and had to keep it at 3/4 to full throttle. Now it flies with enough power to really fly it like the real one. If you watch videos of the full scale Bronco you will see them throwing that plane all around the sky. I don't mean acrobatic, but it will bank and yank and have enough power to do a climbing turn that's fun to watch. Now I can finish up the final detailing and put on the pods onto the fuselage.
One final note, the hinges on the ailerons came loose again. This is the second time the CA didn't want to hold. I'm going to pin the hinges from the bottom or go to nylon hinges. Sorry about no video but Motion has a video from Joe Nall and mine looks the same flying. The flaps are very effective and slow the plane down nicely. I have to put a little more down in the elevator since it still balloons a bit. Overall, I'm glad that Motion started carrying this since it has always been one of my favorite planes. I just wish some one would have one flying at an airshow to put it through it's paces. There's currently an OV 1 Mohawk that is being flown at airshows and this would make another great subject.

I regret that i wont have my ride done for the warbird meet this weekend but i am making headway slowly. My biggest hurdle was learning and programming my Taranis X9D+ using dual SBus decoders. I had changed to all digitals due to the SBus output being 9ms, glad i found this out before flying! Now that the radio setup is done i can proceed in installing the servos and linkages and finish applying the graphics. Pics coming once that is done.

Well i have my final test from OpenTX programming on my Taranis radio and using the SBus decoders this weekend. Finally figured out my settings to allow the least connections between the L and R wings using a SBus decoder on each side. I also will be able to use the voltage sensor and amp sensor with logging to my TX to get real flight data.
If anyone is using a Taranis X9D+ on OTx 2.2, i have included my plane file that displays for that model.
I like this radio once i learned the basic programming and settings with all the options i wanted. SO here is my setup
Basic TAER with gear and flaps
Usual DR and Expo
Amp and flight battery pack voltage telemetry
Signal strength and rcvr voltage(default telemetry)
With the SBus decoders, my wing connections are one per side, 4 servo multiconnector(1.Sbus(A,F,E R), 2.ESC, 3.retract, one open for lights later) and the power leads feeding into the fuseAttached Files

Hi all, new to the hobby squawk, been reading a lot though, but it's time to get some activity going....
I might get the Bronco as my next project, and need some more information....
Bronco Mike, you have given it a nice paint job, did you just sand the existing foil and sprayed it? I would certainly want to paint mine if i was to buy one, cause i'm not too keen on the sceme out of the box....
Thx,
Didier
