(https://i.postimg.cc/0NbRhs72/IMG-20181101-122955307.jpg) This model is being built without plans! Working with the build manual, and some photos/details found on RC Universe Title: Re: Sig Kougar( modified) Post by: sanjayrai55 on November 04, 2018, 04:51:29 AM Wing sections joined

Title: Re: Sig Kougar( modified) Post by: sanjayrai55 on November 05, 2018, 05:04:27 AM Thanks Mehul. Still a long way to go!
Title: Re: Sig Kougar( modified) Post by: sanjayrai55 on November 05, 2018, 07:15:31 PM I considered using 3 mm balsa sheeting for the fuselage. But after some consideration, I realised it would add about 150 grams, a lot more work, and Corro would work fine
Plus, if I don't use some corro, it would be OoC ;) Title: Re: Sig Kougar( modified) Post by: prabal276 on November 05, 2018, 09:33:46 PM What is OOC? ;D
Great build sir! -Prabal Title: Re: Sig Kougar( modified) Post by: K K Iyer on November 06, 2018, 01:19:24 AM What is OOC? ;D Great build sir! -Prabal Haha. Try to guess.

Prabal, OoC is "Out of Character" Title: Re: Sig Kougar( modified) Post by: sanjayrai55 on November 06, 2018, 10:34:29 AM Wing is held down by dowels in front, and bolts at the back. Before gluing in the formers I fixed the Dowels, as later there would be no place for the drill once the fuse was assembled

A part of life Not dependent so much on quantity of models, but on how they are stored, and how long they remain idle without being flown Title: Re: Sig Kougar( modified) Post by: sanjayrai55 on November 08, 2018, 07:52:21 AM Need to make a balsa piece for the lower fuselage front.
Supposed to be carved out of a 1"block, I fabricated one instead by gluing strips (https://i.postimg.cc/mkN3tdpq/IMG-20181107-170536201.jpg) (https://i.postimg.cc/wjbXyRF6/IMG-20181107-183342621.jpg) Title: Re: Sig Kougar( modified) Post by: sanjayrai55 on November 08, 2018, 07:53:42 AM Fuelproofing.

Sent from my Moto G (4) using Tapatalk Title: Re: Sig Kougar( modified) Post by: K K Iyer on December 16, 2018, 07:26:57 PM Not at all!
Just looks too fast and fighter like for my skill level (electrics below 300 watts, except for one 40 high wing) Haven’t had the gumption to assemble the Cap 232-46, or to complete the Minare! Perhaps I should try my hand at precision aerobatics before I get TOO old... And btw, my control liners were all Enya 19/ OS 20 powered. I once bought (for 500) a 35 stunter from Mr Nagar, (engine and lines borrowed from him) But after just one flight, and the line tension really scared me. So I returned it. He said once sold is sold, can’t return the money. But he was kind enough to give me an old Merco 35 in exchange. I still have it some 40 years later, though the carb mounting screws are nowhere to be seen... Hope you did the maiden flight today (being Sunday). Await video eagerly. Here’s what a 50+ year old Merco 35 looks like... Title: Re: Sig Kougar( modified) Post by: sanjayrai55 on December 16, 2018, 07:39:41 PM Which Mr. Nagar was that: Vijendra or Ajit?

It was a defective aileron servo extension! Was causing one aileron to jitter badly :violent: Anyway, repaired, extensions changed, and a very smooth remaiden https://youtu.be/Xd_72vdFlf8 Title: Re: Sig Kougar( modified) Post by: sanjayrai55 on February 24, 2019, 05:37:37 PM https://youtu.be/bzXyMTj3NiU

nothing more satisfying than a successful maiden. Title: Re: Sig Kougar( modified) Post by: sanjayrai55 on February 28, 2019, 04:17:22 PM Thanks Manoj :thanks:
This one was particularly satisfying - did a lot of work to make the model, and then crashed on the maiden because of the faulty servo extension :violent: Guess all's well that ends well ;D |
