Thanks.
I watched some videos of the V1200 and the plane lands pretty fast. Even with the flaps. I had the thought of using the thrust reversing capability of the Avian ESC to slow the plane down more. I got it working and put it on the I button so I could try it. I actually still haven't flown the plane yet but I'm getting close. Just curious if anyone else has tried it. |

I had a guy tell me the retracts from 64mm A10 thunderbolt will fit with little trim .I ordered some for mine as it collapsed on maiden and the second flight got stuck in up pos. And right one down couldn't get them to cycle.they worked fine before take off .long story I crashed

That makes sense. I was really surprised how heavy the plane is when I got it. Assuming it survives long enough, I'll give the reversing a try at a high altitude and see what it does. I saw Horizon using the reversing on some big red Tundra type plane and they used it after touch town to make for a quick stop. Maybe that would work. It would be tricky to do.

My motor/spinner/ESC swap dropped 2 lbs from the airplane. Flying with a 4S 3700, no wind, I can get it slow enough now to stay on our 160’ grass runway….IF I can touch down close to brick one. |

This is a link to the manual on the Turbo Timber Evolution. The directions on how to set up thrust reversing are on page 18. Below that is a link to a video I did a while back with the TTE and used reversing on all three landings. It does take practice to get the timing right, especially since the TTE doesn't really need reversing because it can land so slowly. On floats it is very useful. BTW, I have turned on thrust reversing (with plenty of altitude!) on the TTE and the Night Timber X. The result is predictable; it almost stops in midair, the airplane drops like a rock, and you need altitude, and plenty of it, to recover and remember flip the switch back to normal thrust. You'll feel really stupid if you try this without enough altitude.... Someone mentioned using the button switch "I". Before you do that, remember that's also the default for panic mode, so you'll have to turn that off or move it somewhere else or panic mode will come on too. https://www.horizonhobby.com/on/dema...-Manual-EN.pdf Landings with reverse:

Thanks Irving. So you turned it on briefly just before you touch down. That looked perfect. Nice flying. If you get time, update us here how it goes on the V1200. Like supercruise said, it a flying brick.

Before my first flight I figured to get an idea of how long my batteries will last. I have two 4S Turnigy 4000mah 45-90C batteries. They both lasted about 5 minutes with mixed speed flying. But on one of them the voltage sagged down in the 12 volt range right away. I must have abused it in the past. So forget using the voltage to know when to land. I’ll use the timer till I buy some better batteries.

That is an excellent idea. Maybe somebody will come up with that one of these days. You’re right, it’s always one cell that malfunctions early and ruins the whole thing.

I think LiPo batteries are already made that way... single cells bound together into one cohesive unit. I'm wondering if one could buy the separate cells somewhere. In addition to the ability to replace single bad cells I'll bet they'd be far cheaper that way too. Of course there's the wiring and plugs to consider.
EDIT: Is $29 delivered a good price for a 5000mAh 5 Cell? Or $46 for 2 of them? Unfortunately, the discharge rate isn't advertised for these. I'm going to research it a bit more. I think the key is in the battery numbers. Maybe someone here knows? https://www.aliexpress.com/item/1005...51062496%22%7D EDIT #2: It looks like the discharge current rate is 2.5A continuous and 5A burst. This assumes these are the same batteries which I very highly suspect they are. https://ydlbattery.com/products/3-7v...AaAnDBEALw_wcB |

I'm sure that's true. I suppose having one or two more batteries than one needs would provide the spare cells needed for repairs. A 60-70% cost saving on batteries is appealing though.
