Don't wake a Tiger until you've factored the teeth




My first RC Model was an IHC Apple Box, circa 1986 or so. It had a power pod, on which I had mounted an old Fox .09 belonging to my cousin

Since then, I've always been fascinated , by, but never really got down to either flying or building one of these graceful models

Plans here: http://www.outerzone.co.uk/plan_details.asp?ID=6789

Brief Specs: 74"Span, ~1.5 kg, power by 10 nitro equivalent

I would rate this as a difficult build in corro

It is fairly complex, lots of angles everywhere  Cheesy Cheesy

Landing Gear is extraordinary, hand constructed

Lots of adaptation needed from plans

Wing has a double sweep (front and back,) and steep dihedral

I think I've found the secret behind the success of Rai Saheb's models:

1. They have a pilot
2. The pilot has instruments

Congrats on your choice of another really classic plane.

Sanjay
The Fournier is on my to do list and have the same plan from RCM (before it went bust). Good flyer but my intent is to power with an OS 20 FS not the electric. Have also been eyeing MRM 1/4 scale kit that would be a good candidate for the OS 60 Open rocker 

Good effort on your part and I am sure it would be a good flyer.

Few things that I spotted in your previous posts
The Apple box was/is from Sharma and not IHC. IHC had the Orange box that was a design from UK. Plans available on outerzone.
The model has lot of curves not angles Smiley (and that is the reason why we love them curvy ones). Your biggest challenge will be the cowl rest is easy for some one like you. All the best

Don't wake a Tiger until you've factored the teeth



Thank you Captain  Salute

My mistake: Apple Box is indeed Sharma's and the one I built was Orange Box

To the best of my (aging and fuzzy) memory, IHC had a tie-up with Mercury models of the UK, it's chief designer being Henry Nicholls

http://www.rcindia.org/rc-general-topics/remembering-henry-j-nicholls-the-mercury-man/msg176467/#msg176467

But I don't think the Orange Box was by Nicholls. The Outerzone credits  say:
Orange Box 
by Clive Smalley
from Aeromodeller
March 1979

Getting curves in a corro build is never easy. Let's see how it goes; fair bit of work done on the cowling, and turtle deck planned too

Thanks again for the encouragement Cap'n  Salute

Sanjay yes right, while there were a lot of classic Mercury and other models being kitted by Aurora not all were Mercury or HJN product.
For example the Schoolmaster by Ken Willard of US underwent a gender change with Aurora and became Schoolmarm

Don't wake a Tiger until you've factored the teeth



That apart, besides all the Gnomes Mentors Marauders Magpies, there were also the beauty Queens: Miss Universe & Miss World  Grin Plus a decent Citabria

Now on the Fournier, the plans say 4"of Dihedral. It does appear that is each side, making a total of 8". Any ideas if that is correct? Also, in the RCM/Outerzone plans there are no ailerons, but I will be adding half-span ailerons. Should I reduce the dihedral or use the same 8"? Yes, it is needed for rudder turns, especially at lower speeds, and I typically use ailerons only for levelling the wings preferring to turn with rudder

I've used an NTM 2836-1200 KV and plan a 10*6 prop. The original used an Astro 10, this is more powerful, 300 W on 3S compared to 200-220 W of the Astro 10

Yes that is 4" under each wing tip and do not forget the washout.
Since you are using ailerons you can safely reduce the dihedral. With a dihedral wing the rudder induces a rolling moment as well. How much to reduce? I would suggest to to 2 1/2" or even 2" under each wing or look for other Fournier plans with ailerons to see what dihedral they have and interpolate from there. Remember with the original dihedral the aileron will have very reduced authority
Some reference material, hope these help

As for the cowl cheeks above are you planning to hollow them from inside? I suggest you can if you do not need nose weight. You can go really thin and line the inside with glass cloth and epoxy

Thanks Captain

I was planning to go with 3"each side, but will review again

The Alpavia, based on the RF3, has a 56"span, no ailerons, and 4 1/2"dihedral each side

That may not be an apt comparison, as the dihedral will also depend on the fin/rudder size. If you refer the plan for 56 inch Fournier  by Peter Miller on Outer zone you will see the dihedral is 1 3/4 each wing and the model is aileron equipped as well.

I don't think it will be unmaidened, and neither will the cub

I will fly this in 29

Dihedral is specified in reply # 49, and a picture is in reply # 52

Very graceful model....... Both in looks and flying..... Guiding a 1.5 kg model is well achieved by 74 inch wings

I have seen the maiden video on what's app

Don't wake a Tiger until you've factored the teeth



Flight Report:

For a maiden, it was remarkably smooth. Just needed a little uptrim. I wanted to hand launch, but then decided to do a ground take-off in case I wanted to abort

Battery consumption is very low. I used a 3000 mAh (for CG reasons) and as per my wattmeter was left with 87% battery after 3:34 minutes. This was exclusive of initial testing. With this battery, 2-25 minute sorties are a reality Cheesy

My aileron throws, at low rates just 12 mm up and 8 mm down, were too high!! Granted one needs time to get used to the model, but it could turn on a 1 naya paisa coin  Wink

Landing: knocked me for a Six! Just kept gliding on and on and on  Shocked  Finally landed in a puddle of keechad

But what a pleasure to fly. Fast, very fast. I was flying at less than 1/3rd throttle, but still fast! And graceful, very graceful. Really u-turned my concept of Gliders

Now I have to figure out the 'slip' method you advised to reduce speed and height for landing. Flaps of course can't be fitted

Iyer sir

Thanks. Yes, it does fly pretty fast; except the take-off I was flying at less than half throttle!

Oh, and it glides - endlessly Cheesy

Drove me crazy while landing -just went on and on and on!

@sanjayrai55,
Just went through the whole thread and video again.
Was thinking she flies more like my aerobatic Pilatus B4 than the Sunbird.
Was going to suggest you try aerobatics rather than soaring, but before that i Googled RF4.
Guess what i found?
The RF4 is the aerobatic version of the RF3 Grin

So, ladies and gentlemen,
In the next video from Rai saheb,
Expect shark teeth and inverted low passes at high speed with red and green smoke from wingtips...

@sanjayrai55,
Just went through the whole thread and video again.
Was thinking she flies more like my aerobatic Pilatus B4 than the Sunbird.
Was going to suggest you try aerobatics rather than soaring, but before that i Googled RF4.
Guess what i found?
The RF4 is the aerobatic version of the RF3 Grin

So, ladies and gentlemen,
In the next video from Rai saheb,
Expect shark teeth and inverted low passes at high speed with red and green smoke from wingtips...

Sirji,
Since you liked that Turbine Fox so much, we await “inverted low passes at high speed with red and green smoke from wingtips...”

So far I’ve only seen pics of you in half pants...
And coupled with your numerous and prodigious builds,
I expect you are young enough for high speed inverted low passes...

Aah Iyer sir, if you think I am young (not younger Wink ) then you are a really nice man

A few years ago I would do crazy aerobatics. But now, I'm content with just building and flying
