I never learned the square manoeuvres, triangles, hourglass and four leaf clover!

All others possible with a Peacemaker on an OS Max 20, 8x6 prop, 52 foot lines.
About 4 secs per lap at about 100kmph.
Rather faster pilot rotation than with, say, a Nobler with a Fox 35 on 60' lines...

If you are getting into C/L for the first time, then I recommend something like this (see pic) as your first model. Cox Babe Bee 049, 6x3 prop, 30' dacron lines.

At you service for more...

Here is Fox 35 stunt motor which is a tough machine.  In mid 80s, it powered Flite Streak Combat control line model from Topflite.  It had a control line of 60 ft.  Prop 10x6.  Flite Streak now available only in ARF.  

This particular engine is carefully maintained and still has no sign of rust.  It's a powerful motor with excellent compression.

A Cox PT-19 U control model powered by .049 Cox engine can be an excellent control line  model for beginners as it provides four engine thrust postions from novice to expert if someone can still source it.  A very stable flyer at novice position.

Have two Skybees that are built and a Aurora Tyro still in kit box. Have 1.5 cc and 0.75 cc engines cleaned and ready for bench test. They were boxed for over 15 years. Managed to source ether. Kerosene is very difficult to get in open market ever since it is no longer available from ration shops. Will have to try and get them in the air before the monsoons hit in June.

I have flown control line models when I was part of NCC (Unit 1 Guj Air NCC) and thereafter for quite some time.
Can share my experiences on flying control line (C/L) aerobatic model.

As suggested by "sanjayrai55", Vivek Sharma of Sharma Models is also the right person for C/L.  I can provide his number, if "sanjayrai55" has not already provided. 

Sharma Model Aero Engines & Propellers are in to C/L for a very long time.  They sell SENIOR PEACEMAKE C/L models which is a good model to learn C/L flying.

Happy Flying.....

Start with what you already have. SkyBee is a good beginners model. Second the Peacemaker too but it takes time to build it correctly as any other good model airplane. A larger model like the two mentioned above will increase your chances of learning CL and aid in reducing the dizziness over the small 1/2A models. Longer lines help a lot.

Thanks for the inputs. The Tyro is a smaller model with lower power engine. Thought it would be slower- so easier to control.
Saw this on Facebook- seems interesting what the Philippines CL flyers are doing .
The model seems very stable and slow.
Indoor CL is a good option during monsoons.

At the risk of scandalizing the purists, there is a pretty wide range of electric CL models available. I remember some time ago RC Bazaar had some. Easy to use and lots of fun

Bigger model, longer the  line, slower it flies. Best for newcomers. I would start using what I have and just begin. You want to be around 5.5 to 6 seconds a round.

Those electric fliers in the link would be good too, lighter the model foamy, less chance of higher breaks. But cannot get those plans and details.

Yes - electric CL is an option that can be considered especially for indoor.
Less problems for beginners - engine starting problems etc.
Have found getting kerosene is a problem nowadays.
Have a design and plan down loaded where the battery pack is in a belt with the flyer and the line runs to the model. Switch on handle - so can start stop as required.  Was a profile design. Will dig it out and post

and then, we have this too

What about CL combat??

So much to do and master in just the CL world.

    

I'm building Senior Peace Maker and just paused it due to my exams.
Senior peacemaker's Ribs are of normal ply, not balsa.
I think if it crashes, then it will be difficult to repair the ribs part.

Yes, Kerosene is tough to find even in Delhi NCR.

Till now, only one wholesaler of Keroscene from Gurgaon Sector 10 is agreed to sell in small quantities if I inform him in advance.
But I'm not worried as my control line instructor prepares diesel fuel for me

Nitro engines for control line is a way better in terms of speed, easy start and fuel cost.
Methanol is Rs.45~60 per litre and Caster oil for Rs.150~250 per litre in Ghaziabad.

Cool, nice workmanship.

Your model coming up well.
Good to have an instructor to help in the learning process.
Where do you source your nitro engines?

I bought Cox 049 nitro engines from an eBay auction and I bought a 3.2cc diesel engine from Sharma Models for my senior peacemaker.
Btw, I have flown my instructor's Skybee with my 3.2cc diesel engine for level flying.

3.2 cc is pretty powerful for Skybee. 1.5 or 2 cc sis enough I think for level flights.
My Skybee had a 1.5 cc engine Ithink when I recently dismantled it to clean the engine that was not used for 20 years. I dismantled all the parts - changed the gaskets . Now need to bench test it.

Found a pic of me doing a wingover at Safdarjung.
About 40-45 years ago!

Nostalgic memories keep the interest going. Each different aspect or category of Aeromodelling has its own excitement , challenges and expertise required.
