Oh I seen the canopy fly off first hand, and the damage from it falling off

[Beeg]

I might have to grab one of these. They look so cool flying.

They're a great flying model but as others have noted be sure to mod the canopy for security. Mine flew off on it's maiden flight not heeding the warning others have presented.

I'm flying mine with the Spektrum AR637T with Relative Gain settings at a maximum at 40%. I've dialed the settings back to about 37% to take out the "Tail Wag" as Xviper mentioned. I sure enjoy flying this plane.

I am using a Horus 10X and a S6R which makes a big difference between when the stabilization is on or off. With it on, it flys smoother in the turns and thats just with the rudder gains set to use as a yaw dampner. Gyro help on yaw axis is highly recommended and its 13 mins of enjoyable flying on box stock config.

[Mad Baron]

It seemed squirrelly to me but I suppose its more of the tail wag, so I will get a gyro to see if it helps this plane out. Thanks for the help!

[xviper]

I flew my OV10 today and it flew good but it was squirrely I'm thinking I need to put an gyro in it to see if it will help with the flight quality. Its been a long time since I installed a gyro but I only have a 6 channel radio and every channel is being used.

What do you mean by "squirrelly". Do you mean the infamous tail wag as you are coming out of a banked turn? If that's the case, all you need is the simplest, cheapest gyro to get this plane to fly solid. Something like a HobbyEagle A3-L or Freewing gyro. You don't need to have an extra channel to switch it on or off or to have the ability to control the master gain on a knob (extra channel needed). Fly the plane and have it trimmed as well as you can, then you install the gyro in the proper manner and start very conservatively with the rate gain pot set low (say ~25% of its full travel). The heading gain should be set to zero on this plane. When no leads are plugged in to control "mode" or master gain, it's just ON all the time. After you do your first flight to make sure the gain is OK and the plane doesn't do anything weird like oscillating in any axis at full speed, land it and turn the gain pot up just a hair (say to ~30%). Take it up again and do a fast pass, if no oscillation occurs (and you'll see the oscillation on the roll axis first), land and again turn it up a hair. Continual to do this until you see aileron oscillation, slow down immediately and land, dial back the gain just a tiny bit and it's all set and good to go for the rest of the time you fly this plane as is.
However, if you mean it's doing something else when you say squirrelly, you'll have to describe it better. In terms of roll and pitch axis, this plane flies very well. It just could use a bit of a "yaw damper" like in some of the big airliner jets to control the tail waggle a bit.

hope it works out for ya we need pics lol

Here is the battery I use in my OV-10, from Amazon 1 ZEEE 7200ma 4 cell 80-100c, and price is reasonable. Zeee 4S 14.8V 7200mAh 80C RC LiPo Battery Hard Case with EC5 Connector. Reduces the weight overall, and replaced the motors with a 5 for $42.00 deal I found on Amazon...Drop-in replacements, and changed to the Tigercat Props, with their hardware. KV rating of 920. The motors are branded "Exceed". Amazing change to the available power. It flies like it should have from the start....It is a half trottle plane now, with plenty of overhead. Bronco Mike

Anyone having trouble with the flaps not going down smoothly? When I actuate the flaps they chatter on the way down. I don't believe its my receiver I wonder if it could be the blue box?

Could be. Plug them in one at a time (if you can) into a servo tester and run them through their range of travel and see if you can reproduce it.

I am using the Tiger Cats EDCs which are the same as the P-38 but some Hobby Star motors. My complete setup has been listed in this and the RCU thread. Currently using Socokin 3500 packs and love them.

yes it’s awesome to have MotoGP back!

[SanExup]

Evan D You are using the P38 power system, escs, motor, and props? Is it a straight drop in replacement? Did you use the F7 prop adapters and spinners? I can't remember if it's just a matter of swapping wires to reverse the motor for counter rotating or is it better to do it through the esc programming? And lastly what is your favorite battery for this setup?

And I hope you have been watching Motogp! Doha is not the most exciting track for television speculating but it was fun to see them racing again and breaking speed records and fastest lap times.

[xviper]

Yes, he could. However, when he said he flies it with 2 X 4000's, I just extrapolated to him meaning 2 X 7000. Since he's maintaining 50C, there isn't any advantage to going to a single 7000 from twin 4000's. The savings in weight wouldn't give him any significant extra punch.

[Evan D]

He could fly off a single 4S 7000...

[xviper]

One more thing comes to mind. You say you ordered 2 X 7000mah batteries. 2 X 7000mah, 4s batteries won't fit in this plane, UNLESS you are talking about 3s batteries, in which case, if you are flying this plane on 3s batteries, no wonder it's as anemic as you say it is.

[Evan D]

To add to Xviper... What altitude are you at, that can affect performance. Did you calibrate the ESCs so you get "full" power?

But all that said the stock power is very low. I built mine with a much hotter power set up, about 3X, and absolutely love it. Takes off in 3' and unlimited vertical, throttle differential for spins, Tons of flaps available as well as crow and rudder airbrakes... And FPV. I love my Bronco!

Does anyone have the same problem? With 2 4000 50c, it barely takes off and doesn't have speed to climb at a normal rate. I wasn't expecting a speed racer, but 2 flight, 3 left turns and 2 harrowing landings barely escaping disaster, I thinking of upgrading the motors and esc's.. I ordered 2 7000 50c batteries but not sure the stock esc could handle it. Advice?

1. You didn't install the props backwards, did you? (IE, there's front side and a back side.)
1.a. There is a right prop and a left prop. Did you get them mixed up and reverse the rotation? Looking at each prop's top blade - it should be turning towards the plane.
2. It's NOT the "C" rating of the battery that the ESC can or can't handle. It's increasing the cell count that may create a problem.
