" Latest update.

We are upgrading the battery pack to 117V. This will add 42 pounds (9% total increase), but increase the HP by 40%.

Change the gear ratio from 4.4 to 4.9.
Changed to a Thumb throttle.
Should get us to the Mid 8 second range (1/8 mile).

Painting on the body and fender has started!!

" Here is an interesting video showing ten electric aircraft. They are all kind of cool, but still have a way to go before they start carrying paying passengers. I looks like we still need much better batteries to keep these things in the air for very long: https://www.youtube.com/watch?v=abtj87wAX0Q "

" Thanks for the focusing my direction everyone! I will move forward with the stuff I already have, but design motor and battery mounts with expansion in mind. I have to adjust the motor mount by less than 2 cm to make room for a 50kw motor in the future. I have space to leave room for a few extra leaf modules to get me to the gen4 size 6 max voltage too. I will check the max voltage I will be able to tweak my charger to as well, before I fab up the mounts.
In the past year, I have only half rebuilt the brake calipers. I'm getting excited to get it going again! "

I desprately need to finalise the motor/controller so I can begin mockups and build the mounting brackets. Currently the Agni 119R is the preferred choice, but I'm also looking at the AC-20 as an option. The biggest advantage of the Agni is, it's locally manufactured and available. Also, it's fairly light and compact. But the dual motor setup is going to run me about $5,500 including taxes, etc... Conversion rate is approx $1 = INR 70.

" Andrew, if you haven't already made your motor mount yet, just design in enough space to add a larger diameter motor. Same bolt pattern and hole cut out. But also check the bolt pattern in relation to the 3 phase wires if your frame rails are narrow. I had to pivot my motor so the bolt pattern changed position. "

" The BOLT pattern is the same. The ME1616 motor is quite a bit larger and heavier though. The diameter of the motor is larger. "

The me 1616 is the same size ,(bolt pattern) as a me1003? It's so much bigger I thought. ?

This is the 3rd brushed motor i've Nuked in 8 years... I'm over it, want to go Brushless.

Option 3: Slam in a Motenergy 1003 dual-brush motor and deal with DC power... $650 (Don't really want to do this, but cost is tempting)

THanks for the input.
If you do want a me1003, I have and a axe 7245 for sale.
With work great but I'm also upgrading to brush less.
Let me know and we can work something out.

" Kelly specs are pretty optimistic in my experience, so maybe do some research to see what others say lately about that combo.

The me1115 (or even me1114 motor) is good, air cooled. They're the same Stator and Rotor as the ME1302/1304 respectively. I've got Sevcon files for the 1304, and we could likely modify my Size 4 file for the 1302 to fit the size 6. Might be able to find you a used Size 4 that would fit easier as well. "
