Another video uploaded by Gauravag, with a very interesting looking slow flying pusher plane/glider.  Was this built out of some plan ?

Can gaurav  or any one else give me the plans of the pusher shown here. it is really awsome....

No, I got it mixed up Anwar,

I was referring to the flying wing a little more up the page. I realise the pusher type are hard to breal but the flying wing has me intrigued as to why the prop doesn't break because there is no undercarriage and little space between the plane and ground. I wonder if anyone has a photo of how motors are mounted on large flying wings. I would really appreciate any info on this matter.

Sorry Anwar I thought it was you flying the wing but again you posted it for another flyer, that's what confused me.

Cheers to all.  Stuart

Since the prop is on freely rotating motor shaft, it will move away in case it hits ground. I have had scratches on the prop, but never broke one.

we had a small break in the showers so i and sujit bhaiya(raja_mastana) went out to the airoli field to fly. i flew the yak and he flew his hk450

the full flight videos of both the aircrafts are posted below

i have also posted a video of the airoli field just so that others could have a look at its present state. all cricket activity has ceased to continue due to the rains as shall be evident from the video.

also attached are a few pictures

had great fun today flew two sorties on the yak 55 and we had a little meet at the ground

saurab had brought his blu baby for maiden which did not go well due to high winds and ameet narvekar uncle had come to meet us too.

we did more flying than video shooting so i put together a small video of today's activities at the airoli field

watch it in widescreen mode at 720p


also attached is a pic my father took of us all

had some  awesome flying to day..! 7 flights 4 models

a .40 strega, .40 calamato, .40 classic, any my ZZIP soarer...!

tied  one maneuver today... launched the ZZIP soarer by hand and then caught it back before  landing...!
the plane never touched the ground for 2 flights...!!

we had  a  visitor today..! Wg cdr AJIT KUMAR(retd) had good time talking to him also....

on the bad side.. nobody took pics...!

Flew 3 packs today morning, everything seemed fine. On the 4th pack, i was coming in upright, going inverted and immediately pulling back both sticks so heli goes high up and comes upright nose in. Did this once, it was fine, on the second attempt there was tail blowout (as soon as i pulled back on both the sticks) and i completely lost control. I never had a tail blowout on me before. Damage is pretty bad. Any ides what caused it?

I was using  the dual push tail mechanism and some HK tail blades (in the past i had the single tail rotor control arm and KBDD blades)

real life heli has Four major reasons for Tail Rotor failure (a) Drive failure (Belt may be) (b) Servo/linkage failure (d) Overload (e) Electronics glitch

Overload (motor?) and Electronics glitch might be a possibility.

Possibly there was a drop in headspeed because of motor overload which caused the blowout. That reminds me i can check the CC log to confirm this.

Also, I did the maneuver once, so it seems there was enough pitch in the blades to stay steady.

Sounds like you are applying full pitch and cyclic. It will load the head too much. Any gyro will loose control if you load the head too much (there simply isn't enough tail rotor RPM to have authority). The cheaper gyros aren't that good dealing with maneuvers. From you sig, it looks like you are using Quark, it is one of the better ones, so I'd suspect head speed first. Also look for any play in the whole tail system. It should be butter smooth, but without any play.

Also check the gyro mount if it is too loose.

Try to do the maneuver with as little cyclic and collective. It certainly doesn't need extreme inputs. Keep the head RPM in mind always during flying, allow time for RPM to recover if you have loaded the head too much. Do not go from one heavy pitch maneuver to another without allowing RPM to recover.

There is a little play in the tail (near the linkage rod), not too much. The slider moves smooth in both directions, no problem there.
Gyro mount is also fine. Using a 4mm tape to hold the gyro.

QuoteKeep the head RPM in mind always during flying, allow time for RPM to recover if you have loaded the head too much

I agree with this - if i have given 2 secs for RPM to recover, it might have been a different story.

I combined two moves and i had a failure, wonder how the 3d pilots do all those complex moves without any failures 

Enjoy some more view of Airoli, Navi Mumbai

Pilot is Subbu

Wow. Awesome flight.

thanks sujit bhaiya for the video  , after the total 13 minutes of flight the battery still was at 11.7V that means we could have flown another 5 to 10 mins
the 2200 3S Lipo is a beast for the easyfly

thanks hyd_quads


Subbu

great great flight.

Had a slope soaring weekend this Sat Sun.
Flew everything from Foamys to Composite moldies to heavy wing loading flying wings

some pre fpv flight done over the weekend. windy weather not allowing to start fpv

http://www.youtube.com/watch?v=M3c3L8XCegQ&list=HL1343130353&feature=mh_lolz

Today's been a big day for me, novice. My second quad (MultiWii, dt700s, 18A SS series, 10x6 GWS-style) has hovered (~1ft.) at just 15% throttle. 

Dual channel U-shaped Al rods (used as rails for sliding glass panes in showcases, they're ultra hard)
Centre made of an examination pad made of some thermosetting fibre. (I remember reading this idea on RCI itself)

Vineet

My day:

A little bit of wind, that urge to see the heli flying, that feeling of urgency ... took put the 450 v2, put in the battery, took it to the roof (my fav. spot to fly) and hovered tail in for about 2 mins when suddenly a gust of wind came and knocked the heli on the ground ... boom ... a few broken parts at hand.

The feeling was not just sad, it was a mixed bag, this 450 v2 is an RTF version, just like a virgin, waiting to be explored. Was a bit excited, lets see how i can open it up and see if i can get it all packed up to fly again.

Kept it on my workbench, initial examination shows a few parts to be replaced:
1. flybar
2. landing skids
3. tail boom
4. vertical fin
5. tail boom support rod
6. tail assembly
7. main blades

Good part is that i had most of these spares handy, so the operation started and i slowly started to open her up, slowly studing where to start and how to keep her sanity intact

Lets start with the flybar, was the thought, Ok, agreed the impatient me.

To Be Continued...

today was a Fun Day

dude, you have got a nice helipad there  ..
seems to be a underground-tank lid..

Yeah it'sa underground tank we are planning to add a cricle and H in it.

Was invited to visit the Wings India field yesterday in Mumbai.

Very kind hospitality extended by Nandan, Dosu and all others.

Lucky you! :)Those are some serious stuff

Hi All,

Doc and me having some fun in morning. here's a small video of a Roll --testing cam close ups
