Thanks for the compliments Bazhound and Treetopper! I`ve been building/flying racing quads lately, starting to miss flying my 250`s. Going to have to dust them off and get `em back in the air.

Just bought myself a syma x7. Its no racing quad bjt pretty fun. If onky the yaw rate could be increased its sloooooooow even with devo tx.

I love mhy 250. Now that its flying well im getting more confident with it. Now stsrting more inverted flying

Great! Looks like you have the 250 flying very well. And, good on you doing flips already!

I've been concentrating solely on the simulator for all of winter. I hope I can still fly 'real' helicopters ...

I have been simming with the 250 and the Oxy3 in Heli-X. I felt that the Heli-X 250 was rather similar to the real thing. I only use the larger models to slow down moves so I can focus on the stick movements.

I have phoenix, realflight 7.5 and clearview. none of them small helicopters that well. even 450 size is weird.

ive never flown larger than 450 but the 600 and 700's feel good, beloow 500 is just weird. the 450's are nothing like my 450. not only do they not fly like my 450 they also sound like wasps in a bottle.

Even so, I find the simulator builds muscle memory, and it does a great job of helping me explore new moves without costing me a fortune in repairs. If I cannot do a move in the simulator, then there's no way I can do it in real life. Also, if the weather is bad, it helps me satisfy my need for flying.

I second that, sim is a great learning place.

im trying to use the sim to learn but i find it does not translate well to my real flying.

in the sim im doing hurricanes , funnels (though with only 50% success rate) stall turns, loops. flips and rolls in all orientations. and half piro flips.

IRL im still flying slowly around, cant do stall turns, not even dared try a loop. My flips are carefully planned and almost alwasy tail in 45 degrees.

anyway,

new canopy paint job, probably added a good 20g weight lol

Have patience, and work on improving that 50% success rate and you'll see a difference. You will.

The biggest barrier to applying what I do in the sim to real life is simply knowing that in real life, the helicopter is really real. That knowledge creates a psychological inhibition, but whenever I have gotten myself into strange situations, the sim-training kicked in and helped me to bring the heli home. So, I'm convinced the simulator helps, even if slowly.

By the way, your 250 looks great! Tail fin should be pointing rearward, though.

The problem i have with the sim is its so different to real life that i feel ive learnt how to fly the computer and non of it applies so if i flyt he sim a week, once i get back to real life its like ive went back several steps.

while i get better in the sim, i get worse in real life

Was just gong through my bar setup as i had bound it to another sat (testing for my 450) and noticed that my main gain was down at 20 and agility at 90!!

whooops that may explain the slightly slow fips

Had the 250 out in pretty windy conditions. was actually surprised at how well it handled.

[ame="https://www.youtube.com/watch?v=VNWzfpXYlSE"]Trex 250 @ fannyside Road - YouTube[/ame]

the only issue was the wind was coming from behind me, the first flip i did i never thought id get the heli back is it went over 100m away and was just a tiny shape. I basically just had to pull back and give almost full collective watching the sahpe making sure it didnt fall down or go any higher until i could see the tail again.

video is pretty shakey, fist time using head cam with less than ideal camera (no stabilisation) and no way of seeing waht the camera is seeing.

That's some pretty vast, open space you have there. Good job on those flips! I had a V120D02S get away from me once--just zipped out and turned into a tiny black spot. Just had to patiently guide the black spot closer until it looked like a helicopter again.

Yeah its the only space nearby where i dont feel like someone could walk up to me at any point or walk out into my flight path.

The only issue is the wind, its always more wind there and the wind tends to be always from behind.

The land is pretty boggy aswell, i think its a pete bog with heather growing so im not keen on trying to recover a crashed heli, might even possibly to loose one if you crash it hard onto a puddle

I had upped the gain previously from 40 to 50 to see if that helped it in the wind, i think it did the trick.

ive done some tweaks now with a few points down on the p gain which is sorting the sto pbounce and also getting the tail locked in better. now that i dropped the p gain i could increase the overall gain and BOOM the tail stopped randomly wagging in the wind. and now the piro rate is consistant instead of speeding up and down.

agility was at 100 on that flight, still slow so ive bumped it up to 120 and lowered the style a little. I think getting the flip/roll rate will help alot. Most of the flips in the video is full forward cyclic.

[ame="https://youtu.be/ObJHBx29Q8A"]250 & 450 summer flying - YouTube[/ame] some more 250 flying (aswell as the 450)

i had a look at the land a little bit more, turns out its not as bad as i thoughtl right infront of the concrete floor is a pond about say 30-40 meteres wide and 3-4 meteres long. theres actually a sort of bridge in the middle that you can walk over to get to the other side. beyond that its all petey land and looks pretty dry with some soggy bits here and there and then a small loch.

So crash recovery wouldnt be too bad, just avoid crashing near your landing zone as you could end up in the pond!!!

[ame="https://youtu.be/ObJHBx29Q8A"]250 & 450 summer flying - YouTube[/ame]

something weird happened during a roll, its hard to see in the video as it went out of focus but it looks like the tail shifted clockwise as it came out of the rolll. I couldnt see well as the heli too close to me so almost above and i was looking up so couldnt quite see what was going on i just new something was wrong and saved it.
