Something more than meets the eye is wrong with the Falcon. After the rebuild and tune up I just got back in from flying a couple of packs. My tail authority is gone. The tail kicks right 90 degrees on even the slightest throttle increase and pulling it back is all but impossible. It will hold when I am in stable flight but the minute I have to increase the throttle to keep it level the dance begins again. I messed with the prop pot to try and correct it and it just gets worse and worse. I had no issues before the crash today. the tail was holding fine with no real noticable movment during throttle increases. I wonder what is my problem? Is it the tail motor was actually damaged during the fiasco this morning? Or is the gyro in the 4-1 damaged slightly to where it does not hold as well as it was? Needless to say i am not in a very good mood. Any thought that may help. I wouldn't think you could destroy a little tail motor just from crash damage. It couldn't be dying by itself, it only has 16 flights on it. Sigh..

Good looking paint job RMG. I still fly the CX2 when i get a chance. I enjoy sooming it around small spaces when I don't have the space for Falcon flight. Plus it's still a blast to take to the gym or outside on calm days and push to the limits of what it can do. Plus i really don't care if i crash it so i fly it like it's someone elses


UTM, the only time I ever had simlar problems with my FP to what you describe is when my TX had a sticky controller that I had to spray out with electrical cleaner (Solos advice), and when my original tail motor started going bad. Your problem might be something totally different???

OK, I'll talk to the coyotes or elk and see what they have to say.
Maybe I can get one of the hawks, that always seem to show up every time I spool up outside, to land and give me some pointers.

I think you get the point.
It's not like I live out in the wilderness but I think I'm a pioneer when it comes to these helis around here.

Actually I do know of one guy that flys a TREX to take aerial pictures but that's about it.
He said he only knows of a couple of guys that fly helis and they're all nitros.
One day this summer I'll try to hook up with them. It's better than nothing.

Thank you, kind sir!

Just wait until some of the snow melts down and I can get to some of the more scenic spots.
It's kinda tough right now, wading through four feet of snow with a camera in one hand and my heli in the other.

Check out my gallery.
There are some really nice, scenic, CX2 pics there.
That is if you like that sort of thing.

BTW, I'm not a photographer by any means.
It's pretty hard to take a bad picture out here with this landscape.

RMG, Thanks for the kind words on my progress.

Wolf, don't complain about the lack of help, you have wonderful views I am very jealous of!

UTM, been there done that. I got my #4 first thing and after 2 weeks let a CX2 friend fly it. He went up about 15 feet and smashed it into the wall! You can let other CX2 people fly it, just tell them never NEVER go above their waist. Use RAADs flight technique. I tell people (the one person who has flown it) to stay withing 2 or 3 feet of a spot on the ground and to land if they go past it. Your 4n1 might be shot if he did not cut the throttle right away, make him buy you a new one anyway . Sounds like you did ok with your flying. It helps to have a calm day and more room then a living room for learning these things.

It sure did. I was flying slow back an forth patterns with great success. I am still not comfortable going nose-in to bring it back so I was taking it out flying around and then pulling it back tail-in. Looked pretty silly I'm sure. I was really looking forward to doing some more yesterday until my disaster. I didn't get a chance to put her back together until the evening and then can't hold the tail so I only got 1 pack on a day when I should've been flying all day outside. I think max wind gusts here yesterday were on the order of 3mph. My own fault though. I did let him fly it. I just hope I can solve my problem today and get her back up. I'm already feeling twitchy with heli withdraw

UTM, I still fly my FP back to myself backwards most of the time. Part of the time I fly it in from the side but rarely directly toward myself except for maybe short distance in transition from one heading to another. I agree, kinda funny looking when I come swooping down from a side-to-side run and go to hover in front of myself, then turn the tail in and back into the parking spot

We all learn this stuff at different rates, but sticking with it will get everyone over the "hump" Trouble is I have great hand-eye coordination and I usually learn this stuff very quickly! I'm being humbled by this heli flying, it's taking me much longer than I thought it would. Oh well, I am savoring the learning and modding so it just adds to the fun for me

Even though I haven't mastered the FP yet, I will have to admit, I have a list of all the stuff I need for my first CP completed and it's just a matter of the right day coming along when I order it all up

Here is a link to some shims that will allow you to adjust the pitch on your woodies.

I'm so excited my fingers are still trembling!!! I just came back from my second excursion to the park with my FP. I finally made it down to the large multi-field soccer/baseball complex I have been wanting to go to. Wide open space for hundreds of yards.

First pack my palms were sweaty and I was shaking like a dog shi*in' prune pits With my back to the sun and clear sky in front the FP went skyward! Hover out front to check trim on gyro (temp. sensitive). Couple clicks trim and drift is gone. Off we go, with left and right stall turns! Lots of room and no background clutter to lose the heli in like in the back yard! Eating-up sky like in my old fixed wing days! Heli gaining altitude with each pass and hard to tell orientation! I tell myself, "fly it down, don't chop the throttle"! Put the nose down and haul arse for the ground, it works! Keeping it in closer and learning how differently it flys in FFF verses hover! Couple close calls as very high speed nose down passes getting close to the ground! Lost orientation once and zoomed over my head and straight into the sun! Some how the heli swings out of direct line with the sun and I fly it back around in front! Pack finished, and so am I My pits are soaked with sweat and my hands are wet! Walking back to the Suburban for a new batt. and a smile finally comes as I realize, "I can fly this thing"

Second pack, better control and more confidence! Throwing some piros during FFF passes No close-calls and not quite so nervous, but still tense!

Third pack not nearly so nervous and much more confidence! Better overall control and some long runs of high speed stall turns. Throwing some piros at the top of the stall just before heading back "down the hill" No close-calls and calmed down quite a bit.

The FP flew flawlessly! Gyro worked perfectly and for the first time, I had complete confidence in the tail!


Stuff I learned on my very first day of wide open FFF flying with the FP:

1, Do not let the heli get to far away, it's very easy to do!

2, If you gain to much altitude you must fly the FP back down, you cannot just chop the throttle and settle back down without losing most of your cyclic control!

3, In Fast Forward Flight the heli only requires about 30% throttle stick verses 55% for hover (my setup). Along that line of thought, when you come sweeping down from the heavens at high speed and pull back on the stick to flare, be ready to apply throttle or your going straight to the ground! You are literally going from 30% to maybe 70% throttle briefly to transition from FFF to hover when you make that transition quickly!

4, The FP is WAY easier to fly in the wind when you have enough room to keep your speed up verses slow flight and hover like in the back yard.

5, My stock tail motor with longer Hummingbird rotor seems to keep-up just fine for FFF flight.

6, This FP will fly much faster then I ever imagined it would

I'll probably think of more stuff when I calm down a bit


I am gonna see if my son can help me tomorrow with the camera? If the weather holds, I'll get some video in the morning (cross fingers)!

Sounds great RMG!! I'm excited just reading your post and I wasn't even there. Nice work and good tips for those of us still trying to get there. Excited to see some vid of this hi-speed action.

The part that I photographed is a genuine #4 core. And yes that is a very large VEE. Epoxy sounds good but it isn't? Curious. The metal rod that I pushed through is just the ticket for me. Next I'm going to make a blade stiffener to see how that works. Or I'll mess with the Belt. I think the blades finally dried.
