VC Sir..its awesome...

I thought I will keep it simple. With all due respect to our poet VC ( VC ! Couldn't resist) and bumblebee stuff. In aviation , after an airplane is made. The best of the airframe designers, engine kingpins and avionics Guys are called. They go through the design, and give an independent view. If all of them unanimously pass the design, the airplane goes to the Tarmac. Else it goes back to the drawing board, . Maserati, you airframe is flawed, badly. Since you are on a budget I didn't want you to break your prop, mount and may be bend your motor shaft. The reason for telling you was simple ' save  money' , do flat outs. Plenty of plans on our forum and on the net. Sucesss rate is high. I wouldn't allow your airframe on the Tarmac. Bumble bee sounds poetic, in aviation you need to work from your head, while feeling good from the heart. Listen to the birds and bees, and you are sure make a mistake, worse, discouragement shouldn't take u away from the hobby.
Just a friendly advice.

sir can u tell me about kfm wing design......
thanks
hitesh

Go with flat outs like a Su 30 or something like that. Kfm? Later. Search this forum, you will find your answer. Keep it academically orentientd as far as Kline foggleman s concerned.

Gusty, just you wait.............

If we were to follow all these parameters, we would be better off building static display models! What's life without a bit of experimentation and suspense, eh Gusty me boy?

Which airframe designer would ever dream of certifying this as airworthy? However, the proof is in the video....................

Hi Guys,

Just to break the suspense ... here goes....

Last week Maserati visited the Noida field to take suggestions and have the plane test flown ... I myself looked at the plane and due to the construction, way it was built, material used, battery etc etc ... it was totally non air worthy ( sorry to be so direct), just to pump the emotions I tried taking it in the air but boy was it like mission immposible, the wings would flex if you were to whistle at them leave alone taking the thrust from the spinning prop.... Maserati was given advise by Pankajc a superb scratch builder who visits the field often..... I told Maserati exactly what Augustinev had to say that is learn to fly understand the controls and the mechanics and then start building your stuff.... best of luck Maserati... I am always there if you need any help...

His plane might not be airworthy now...cant we help him fix it and give it a last try? A properly built wing (suggested under cambered to reduce weight) and a wider horizontal stab might make it airworthy. How good it might fly is some thing else...but it might fly once he fixes the probs (wing, horzntl stab, control rods, etc.).

Gusty sir, I'm curious about the KFm airfoils too. I couldn't find much about it here. It would be great if you could start a KFm dedicated tutorial thread when you get your net connection.
I tried building a KFm-4 wing. Please tell me if it's correct and what modifications I should make. Here's what it looks like:


 

Hitesh, I'm a beginner too and I faced the same problems when I started some time ago.

Then I stumbled across Vaibhav's 'Model 1' (1st pic). It's a rectangular planform and seemed really easy to build and fun to fly!
I built it that evening in 3-4 hours! And I've had a really great time flying it.

Now this sort of plane is not recommended for beginners as it can be difficult to control. But if you are really itching to get that awesome feel of flying you could try this one. Just make sure you have a couple of spare cheap props!

The first pic is Vaibhav's 'Model 1' (depron) and the 2nd one is mine (4 mm coro).

See the links in this thread (not just the first one).

Thanks, anwar sir! I guess I didn't search properly!

swapnil thanks for your help.......

Folks,
Have been on PM with Maserati for a few days. Have asked him to collect some information and raw materials and then plan to help him build a bird. The only issue here is that I am out on a tour and return after a couple of weeks

sad...  :

That's why i was advising him to not to take the bird up and waste money, poetic is fine, got to be pragmatic in aviation,
