Hi guys,
I had a hard landing last fall and jammed the left main gear and it stopped working. I ordered a new gear and I am trying to get it installed. I am having a hell of a time trying to figure out how to get the wiring ran. I can’t even see where to unplug the one that is in the plane. Any tips on gear replacement on this would be appreciated.

The FMS and FW are essentially identical in terms of output in my testing. Within ~3-4%, with the thrust, price, weight, speed and efficiency nod(s) going to FMS. That being said it does take a bit of carving to make the FMS fit, whereas the FW is a drop in replacement.
If you don't mind the extra 30 min. of work the 1850kv 6S FMS unit would be my pick, but at the same price (and they're typically much closer in price between one another if sourced from China direct), it's essentially close enough to be a non-factor and I'd defy anyone to identify the fan that was in the plane by how it flew alone.
As it stands, assuming that is the pricing you have, the less expensive FMS unit seems like a no-brainer to me. I hate carving foam, but the pricing delta is significant enough that I'd take the plunge as $158 stings just that much more to me.
I have no experience with Taft, but good experience with FMS and FW, so I'd pick one of those two.

( Hugh Wiedman's favorite 90mm) the FMS 90mm 12 Blade 4068-1850kv @ $116. or just for interest the Taft Hobby 11 Blade 3674-1500kv @ $73. The Freewing weighs in @ 530gr and 3900g thrust, the FMS weighs in at 560gr (the heaviest) 4000g thrust and the Taft weighs in at 430gr and 4400g thrust. On paper the Taft is the way to go. Lighter and more thrust and way less expensive.(but only 11 blade vs 12 blade) So please add some confusion to my decision and pipe in on the pro's and cons for each. Thx.....

I don't know how it compares, but I had a Taft Hobby 90mm Cobra a few years ago (maybe 2018) .... I wasn't impressed and sold it on . Wouldn't buy another one and the stock power setup was 💩
- High Performance EPO Electric Ducted Fan Jet.- With Flap System Installed.- With 90mm EDF (11 Blade) Installed.- With 11 x 9g Digital Metal Gear Servo Installed.- With New Version Full Metal Electric Servoless Retract Landing Gear With Suspension Leg Installed. &nbs

Aros meant to say, great job on the Friday Cameo ... guest starring Todd Breda the Viper Dunkin' Raider... 👍

Just not sure if I'm ready to give it a try and maybe Aros has an idea of trying it out on a "disposable" aircraft (hmmm, now which one is going to be the guinea pig?)
I suspect this is more relevant for those of us out there with 9-blade inrunner setups (80mm or 90mm).
Things were twitching that shouldn't have twitched when I tried it, but then again I felt like I had nothing to lose at the time and had at least had some experience with it on other fixed wing aircraft.
I did try it on my trusty L-39 beforehand.

Just not sure if I'm ready to give it a try and maybe Aros has an idea of trying it out on a "disposable" aircraft (hmmm, now which one is going to be the guinea pig?) Only concerned that I'm so used to throttle placement with my fingers (my visual judgement of actual airspeed kinda sucks in windy conditions), especially on landing approach and landing that I'll be too slow at the lower end of the throttle curve that I'll end up with a wing stall, and the F-18 is not a fun airframe to wing stall at low altitudes. Obviously it worked great for you on battery management but doubt I have the same skills. Interested to hear how it works on your A-10, but since I'm already getting 5 minutes on that and 4 minutes on the F-18, will probably just leave those as is. I used to be able to get an additional indication of EDF "speed" with the older fans from their whining noise, but since I've converted all my 90 mm to the 12 blade inrunner, it's not quite as noticeable.

Hi all, so I was messing around with my (old) DX6 and came up with this curve, which I think is similar to the one I have on my Futaba, for Futaba users an EXP2 curve of 50% worked best for me, lower curves reduced the benefit exponentially (pun intended):
I think I'd maybe try something around 30% throttle @ 50% stick to begin with:

Got a satellite for it that will go up in the nose section and face the same problem up there.

I love the idea of it and I can totally see how it can help manage battery life.
