What did you do with your PRÔTOS today?
Happily flying, minding my own business and this tree just ups a grabs my miniP! How rude.
After a grappling match (slow on TH) and a 20ft fall, I dusted it off, replaced the lower Jesus bolt and carried on flying - try that in a Trex

Accidentally jumped my 500 Protos 25 feet in the air after hitting TH ,while working on a my fault mechanical tail issue. Unlocked the TH as soon as it went up but didn't have auto bailout turned on. Hit square on the skids at a about 500 rpm and full positive pitch, flattened the skids till they splayed out straight bounced up a foot or 2 and landed on its side. Picked it up checked it out, spooled it up, and found out the feathering shaft was bent. Try that with about any other 500 and its game over when the skids snap.

Really Smooth Heli
Flying my stretch Protos 500 today. In the wind and it still flies so good, quite, smooth and precise. Sleek and sits low. Italian design !!! This thing is awesome.
I was flying upside down and doing loops for the first time. Sure glad I have kept this Heli. It is still one of the best !!!!!

Still wish I wouldn't have sold my Mini. they are awesome little Helis, very durable. I kept my stretch 500 though and it flies awesome.

Went out and burnt off 5 packs, tweaked settings a little bit since going to 470 blades, practiced stationary and traveling flips and rolls, as well as straight line traveling slow piro
Thinking about going to 18t tail pulley, or easing up on the pitch. Dropped pitch pump to 25, upped tail gain a couple points as well as pitch precomp. Tail works ok at 2500 rpm struggles at 2400 rpm. and is moving a good 20° if flying backward then pitching nose mostly down for a wall stop. Guess I will start with reducing max pitch a point or 2. Maybe bump p-pump a bit to compensate. might have to turn comps off and retune tail gains. I think if I am going to have to retune any way might be best to go ahead and throw in the 18t pulley first.

From what I've read, doesn't sound like you need a hard-smack-3D machine. Why do you need that much collective, HS, etc.?. I've tried 2450rpm HS with my 470mm narrow-chord blades and it's quite unnecessarily fast. Any higher HS with 12+ degrees collective with 470 blades is hard-smack-3D setup. As posted in other threads, the video shown below I was flying 2400 HS, <10deg cyclic, <12deg collective, 470mm narrow-chord blades, 20T tail gear. It's by no means slow in any way and those "instant" mobius transitions would've killed stock 1-idler/alumin-OWB-pinion yet there's no shortage of tail authority with 20T tail gear. Same for the high speed funnels. No problem with tail authority. And I normally fly even lower HS at 2250 with no tail issue. Just make sure you run close to 45 degrees tail pitch both ways. Yes, you need that much tail pitch.
One thing I can think of is that when you say 2400rpm does your governor hold 2400 well under heavy load? Check out my video, you see 6 "stationary" blades all the time which means governor is holding 2400rpm HS even under the heaviest load. If stock low-rpm motor drops out of efficient rpm range it losses efficiency significantly and may drop HS even more and lose tail authority. When you have enough tail pitch you don't need very high tail speed. More often I hear people try to fix tail authority problem by increasing HS but they actually make the problem worse because with higher HS setting governor may not hold HS as well under load. Sudden drop in HS (and tail speed) is more likely to affect tail authority than a constant lower HS (and tail speed as long as you run enough tail pitch) because when tail speed drops effective tail gain also drops.
EDIT: BTW I did 19 flights today. None of my friends showed up. By myself I just kept flying and did minor tweaks in between. I bought 7 packs. Recharged 4 of my packs 3 times. I was going to fly my 300X or FPV quad but it was so windy (maybe that's why nobody showed up) only my Protos could stand a chance. I was very happy with my stretched Protos handling the wind like nothing. I don't know why people say super light-disc loading gets blown by the wind. I was piro-flipping in the wind and it didn't affect me. My protos is about 1700g AUW with responsive 470mm blades but I didn't feel like pushed around. Pushed up and down a little yes, but not pushed around as long as the swash/FBL setup is good. Maybe the narrow-chord blades help.

I run full 45 ish both sides tail pitch. Problem was at some point i had turned my precomps off and ended up with them set backward after turning back on, gov was struggling a bit as well.
I also ended up coming down on my rpm and pitch a little when I finally got to fly those 470's. I am at 2350, 2400,2450 and 12 ish on collective. Works great thanks for the heads up. Gov is holding quite well now with my current settings. As to why my pitch was so high? Well it certainly isn't because I feel like a smack 3d pilot, I am more like just past SMACK!! frequently. i guess i felt like my 500 should jump as fast or faster than I can move my stick. My also quite light stretch 450 seemed like it did that. Lol, since I didn't start learning to really fly until right before i got the Protos I guess at first I didn't understand that collective response is more like a tire on a road, and less like an afterburner-jet. By that I mean you can only put so much power into it and change direction so fast while still maintaining precise control if you want to stop you need to hit the brakes quite a bit before you actually plan to stop. What I used to think was cool is what I kinda see now as pounding on it for no reason. Once I got the Protos, T-lift kicks in at a much lower speed, it will just float along and for once I felt like I had enough control while in FF to do more than eak out a turn it didn't take long before I learned my first real lesson in collective control. Its ok for heli to take a moment to change directions or react to collective, it is not reasonable to expect the heli to dart off at top speed the very instant you hit max collective, it takes way too much pitch and way too much power to try and make this happen Had it out this evening, and enjoyed just flying around and practicing, controlled ascent/decent both while flying otherwise straight and while turning. If i had it to do over again I would have got a P500 much sooner it is so much more predictable and controllable than my smaller helis.

Ran five packs through and had some fun. I'm getting funnels smaller and closer to the ground lately which is fun and freaky at the same time. Caught a tail blade grip coming loose (despite loctite) on a preflight check - glad I noticed that!

Playing with trees @1400 RPM
I did a little playing in the backyard today at 1400 RPM with some traveling pirouette practice and play with trees.

Couldn't get the you tube of flying through the trees to play "must be my tablet"
Got home from a week long vacation, opened the blades cleaned offf the grass stain and polished her up a bit, checked all the bolts a drop or two of oil here and there. Spooled her up, and got a little test hover in the front yard. Would loved to have flown her over the alantic coast, but I got a me or the heli from my wife. You guys may boo me but, my wife is still #1 and good fun at that, and at least this way I knew I wouldn't dump her into the salt water. Peace deebee Came home to a load of packages in front of the door, and a slip in the box to pick up 2 more, I think I will have all the bits for my stretch as soon as the P.O. opens back up monday.

Nice job and I love the 'landing pad'.

Thanks guys. I prefer a canopy but for bumming around the back yard I sometimes get lazy. The landing pad is nice because it yells at you if you don't have a soft landing.
I did a tail slide later on and nicked the tail blades on the thick grass. No harm, no foul. This was my first CP heli after am MCPx. It was a great purchases. |

I tried to fix the video link. Let me know if it worked. As for the time, I'll need to do some checking on how long I could fly. I was not paying much attention to how long I was flying. My timer is set for 4:40 but I ignored it and probably flew for 7 minutes and put ~1800mAH back into the 3 year old 6S 2600mAH packs.

That's cool. Nice backyard. Looks perfect for FPV proximity-flying a 250 quad.
Here's what I've done long time ago sport-flying my stretched Protos with a 3S 2200 pack for 6 mins easy with higher than storage voltage left. I could parallel 2 2200 packs (still lighter than a 6S 2650) and fly 12 mins easy.

Neat that it flies so well at 1400rpm. No canopy and 3s might get someone the world's lightest protos award.
I had someone at the field today marveling that the heli just has the one belt for main blades and tail. It is pretty cool. On the other hand, I dropped the canopy on cement and someone said "Hey, you crashed it!" Yep.

Wondering if my 430mm blades will even do much more than a weak hover at 1400 rpm. Guess I'll find out.
I also hate crashing canopies when they're not on the model. Rolly canopies, windy days and concrete floors are a bad combination. Just the other day my classic black and orange lid blew off the table, landed right on the nose and took a big black chip off the front

Seeing the low HS videos has inspired me to try it, I feel like I could learn a lot more about collective management. It would make me work for loops, stall turns, rainbows etc. My hopes are that low HS can teach me what the gobs of power available to most every heli on the market can not
Today I changed the HS in my basic gov settings to 1600, 2000, 2400. Did a test hover in the front yard with a light pack at 1600 rpm. It had a surprising amount of power and tail authority (470mm (38 wide) blades, 18t tail pulley) I even banged the collective around, tail held w/ no drama. I also noted it is super quiet at 1600 rpm. Next trip out, I want to try to set the governor to be as flexible as possible, need vice grip rpm hold at at least 2400, and hopefully 2000, I expect 1600 may not have quite as solid of a hold. I am not concerned with heating up the YGE as it is made for this sort of thing. . If anyone has any experience with this, tips for me on the gov settings or gov settings that would suit the situation please let me know I would greatly appreciate it. Flew at 1600 rpm got a descent amount of lift, enough for slow vertical punchout. I am sure I could increase pitch and get more. 2000 rpm is actually nice and smooth, plenty of lift, no real danger of not having enough lift to catch yourself. 2400rpm More than enough ummph here, tail on 18t is really humming wouldn't want to go too much higher. I think around 1900, 2100, and 2400 might be more what i am looking for ATM or 1800, 2200, 2400. I know 2400 is good for top, and 2000 was over what I want for min and just a tad low for a mid speed. Anyhow what i really need the most is to practice and quit boring everyone with needless details about things you guys already know Fly Steady db
