Thanks for that. That definitely will help.
Iâve been considering my first motor and after reading this thread have confirmed my suspicion that this one should be it. Also thinking that as skills progress and desire for higher flight times and budgets grow I can simply add batteries. Heck, I can even imagine extended excursions done by stashing batteries along a route like early aviators in the arctic used to do with fuel depots.

I teach PPG and the standard is gas. Gas will have the advantage for a while but not that long because what Paul and his brother designed is what many of us dreamed of long ago in PPG terms. My students know about my machine (Paulâs design) which I named the VoltAir because I had built an flown other electric prototypes and had given them the name. They have seen my videos and will soon actually see the machine. I already know what the reaction will be 
That said, I sell and train my students on gas setups, knowing that if I could offer them another choice I would, but we are not quite there yet based on their expectations after watching gas versions flying for a few hours on a single tank. My previous electric prototypes worked but they had the same torque problem all one prop machines have. Paulâs was the fix beside the decreased weight factor. I soon will start training them with the Voltair but only for kiting on fields like this one (yesterdayâs session) P2 TRAINING JERSEY - YouTube
The machine without any battery in it will make it the perfect tool for them to learn the PPG moves after they know the PG ones OpenPPG FLIGHT 2 - YouTube

I do not know much about electricity, and yet, I am flying my machine which has been trouble free so far aside from a few non-electrically related minor quacks THE ELECTRIC BUZZARD 7 - YouTube
Which is an awesome wordplay.
If you wanna know more, google âVoltaireâ
and if you donât wanna google: Voltaire was a french Philosopher

Thanks. Every school in France was teaching the classics - I had no choice but learn about Voltaire, Molière, Beaudelaire, and such.
I thought VoltAir was a good name at the time for my electric proto after being the SupâAir US. Distributor for many years.
I think I would like very much to do the same, I must find a way to afford this.
I wish I lived in the USA, I would come study with you.
Peace.
Disclaimer i am not familiar with the setup but the âElectrical stuffâ of a battery powered motor canât be that difficult. The âhard stuffâ is in the engineering and design. I can only imagine on the consumer end changing out a motor and battery is very simpleâŚ
Electric motors rarely if ever will go bad. Bearings wear out eventually but other than that these brushless motors will last forever and never need tuning/tweaking or any parts or maintenance.
The battery will have a cycle life. Maybe 500-1000 charge/discharge cycles and itâll be not worth using. On the OpenPPG you change out the battery every time you want to charge it. Unlike an electric car the charger is not built into the vehicle and the battery is easily pulled out and swapped for a charged one.
Yes, very simple compared to owning and operating a 2 stroke. Charge the battery, drop it in, fly, pull it out. repeat as often as you can! 
Paul and Zach are doing all the hard stuff of ensuring the system is well matched and works together smoothly.
