Flew just fine on one with just a little rudder trim. You're gonna love the way this jet flies!
Can you expand on how having less thrust helped on a one engine condition? i will have Cheetha's 160 in mine, so may need to dial down.

Hey Guys
Just a warning on those new Servo style brakes that they use now. I have them in my 5.5. Do not use more than 5.1v on them. You will burn them out. Use some inline voltage regulators on them.
Main power supply is by Powerbox Royal set at 5.9 output.

Good luck with the build.

I would also agree with Craig that with my experience with Gen 3 with older P-120's and now a Gen 5.5 P-140 Rxi's the 140's work very well with this airframe. I too had a flame out with the Gen 3 in the air and didn't realize the flame out until I was in the pattern on downwind. It definitely got a lot more draggier but still a non event when it came up to landing, just increase the airspeed a little more. Can't relate yet to Craig on the an engine out on take off scenario, thank goodness, but glad to know it can work.
This aircraft was originally designed with 80's in the earlier generations, so maybe we are overpowering them somewhat.

Edgar,
It has to do with controllability with asymmetric thrust if you lose an engine in a high thrust/low-speed condition, particularly when close to the ground (i.e takeoff or go-around). Losing an engine in those conditions will cause a yaw and rolling moment from the running engine that needs to be countered quickly and correctly. The higher the thrust from the running engine, the more control authority is needed to counter it. It's possible in some airframe/engine combinations where there is not enough control authority to overcome the yaw/roll at low speed.

Many of the heavier wing-loaded/high-powered other brand A-10's have met their demise under these conditions. The MIBO A-10, in my experience, is much better able to handle engine-out scenarios although I know of at least one that did not. In any case, overpowering beyond what is needed for single engine flight just makes recovery more difficult. The other key in engine-out situations is to counter the yaw/roll primarily with rudder and not aileron.

Otherwise, how you power your A-10 is a matter of personal preference. Lots of guys like to use bigger engines and in some cases, fly it more like a sport jet. I prefer to fly mine more scale like and have never felt like I needed more power.

BTW, your A-10 looks great and I'm looking forward to following your build!

Craig,
Appreciate taking the time to respond. I'm expect to fly mine in a scale manner as well. I did got Cheetahs as I think the engine size/thrust is quite versatile, but will watch out on this.
I will have telemetry so will be notified on a flame-out, including which engine it is. I may consider having a mix in place that will reduce the max thrust in case of a flame-out on the remaining engine... will need to think thru that one.

Thanks

The mibo doesn't really care if one flames out , almost every scenario has happened ,,on take off while flying over a dozen times even both out downwind the plane recovers extremely well . But when one died keep calm and try not to do a loop or anything it will fly around just as before with less power that's all .

Thanks for sharing. Any comments on the build or plane setup?
I will post more photos of my kit later today.
Thanks

Building an A10 Mibo is a pretty straightforward and clear process. For my gen 5.5 I was just looking carefully for the electronic brake system.

Some picture from my kit. I ordered the plane with the "extra work package #1", so its mostly assembled.

AKB,

What inline voltage regulators are you using?

And Edgar, those pics are very cool! The formers seem to be made of some sort of composite carbon fiber sandwich! How about more pics of the landing gear?

Thank you!

Oh, and how much lead (and where are you putting it, I assume the front) are people finding they need to balance?

Raffy, these are really good and small. Widely used in the soaring community. I have used them a lot when using LiFes

Hi Rav
I have used the Futaba ones they work well. I'm sure that the servo that was included in your set is the same as mine as I got it about a month ago, they are HItec HS 35 HD's, (rated at 4.8v and also checked with Hitec RDC just to make sure) which are discontinued by the way. With this regulator you could put it in the wing before it gets to the strut. Mine is not so inconspicuous, I have mounted it on the strut. They do seem to work better than the electric ones that were supplied with the 5.5.
Good luck with your build. I am sure you will enjoy the aircraft.

It looks like the same Behotec struts as the 5.5, but looks like a change in retract motor has been made. Otherwise same 3D printing on the struts and linkages to the door. Obviously the change again to the servo brakes opposed to the electric brakes on the 5.5.

This is definitely a 'some day' project for me. I WILL have one of these in the future. Doesn't hurt that I get to see them every day either..

I just got mine!!

The boxes are huge and I’ve never seen such a well packaged airplane before.

The fuse is so long, I’ve forgotten how long this thing is! I couldn’t close the tailgate of my F-450!

More pics.

The formers are a carbon fiber fiber sandwich and the glue joints are a thing of beauty.

All that said, my A-10 is missing the Gatling gun! So, I’ll have to make sure I get it.
