Thanks for taking the initiative I'm sure lots will be interessted!

Not too big the loop. Max 395 feet with 5 feet clearance with the ground

Hi Xavier… please count me in! I would appreciate the opportunity to learn from you & the competition aerobatic pilots, to raise my skills in aerobatic maneuvers. Unfortunately I won’t be around this weekend, but please add me to the list for next weekend.

Thank you so much for your generous time and attention to setup this activity!

[Michael O'Bree]

I would very much like to participate when possible.
Thanks to Xavier and the other volunteers.

Well it seems we are advancing!

I spoke with Marcel Bastien and he is ready to go to the field 2 or 3 times a week (I can also be there) to help with Aresti and maneuvers in general, so drop a message here and we will be ready.

Before we continue, I thinks these could be a good guidelines so we can try to go through all of them as necessary to prepare for the final test in September: a one day contest.

So here they are:

1. Aresti reading, maneuvers descriptions.

2. Airplane and radio setup: this might take a bit of time, but in three sessions we should be able to have an airplane ready for Imac.
- For airplanes we focus on mechanical linkages, CG, general airplane adjustments (wing and stab parallel, etc)
- Radio setup: focusing on the throws, exponential, dual rates, etc.

3. Flying sessions: best practices on performing maneuver: straight lines, hesitating rolls, loops.

4. Full routine flying: once we complete item 3 we will do this.


Anything you guys suggest, don't hesitate to let us know.

BTW is this the best way to communicate? How about a WhatsApp group for this? Let me know what you think.

My altimeter is not calibrated!

I would be keen to join in whenever I can, great idea!

I’m interested and would like upscale it to FPV after mastering it

On the subject of trimming an airplane for aerobatics, there are a few different chart on the web.
Here are some links:

I personally use the triangulation method from Bryan and in a few flights, the airplane is 90% good usually.

Any trimming obviously assume the airplane is straight, with no loose control linkage, etc.

Some airplanes have adjustable incidence on the wings and/or the stabs. It allows better trimming. But even without this, it is possible to improve the airplane a lot with basic trimming tests and adjustements. It makes the pilot job easier and it's safer for the plane :-)

All the interest in learning aerobatics is very encouraging! It should be a fun summer! Thanks Xavier, Juan and Marcel for getting this going. I find flying with a plan gives the hobby a lot more meaning.

Hi all:
I am available tomorrow (Sunday the 21st) so we can kick start the IMAC/aerobatics clinic.
I can be at the field after 9 AM, so if anyone can make it please drop a message here and we coordinate.
Also, Marcel Bastien is available two or three times during the week for Aresti reading, flight lines/level and turnaround maneuvers. He will post here which days weather permitting.

All the best!

Juan
