TMG with highest capacity for added payload

[ToddP]

Anyone know what the TMG with the most capacity for added weight?  

is there a TMG with huge fuel tanks and heavy engines and baggage weight to spare?

Interested in EV conversions and wondering what platform would have the highest ability to add battery weight to the aircraft.

Thanks!

The grob 109B has a 26 gallon tank.  Not sure about the A model.  The wings were not as good on the A model.  But I think you can find enough B or A modules that need work that could make the conversion.  

I would look into a https://www.sonexaircraft.com/xenos/  motorglider.

Why do a conversion when you can buy an electric version of the Phoenix (https://www.pure-flight.eu/u15e-onix.html)?

Yes, the Phoenix is the answer whether you buy it ready (if available) or convert it.  It is two place @ 750lbs empty and has 26 gal total fuel, parachute, and a Rotax 912 ULS.  Swap those items out for battery and high KW motor and you have a pretty sweet electric with either short or long wings!!.  Sonex, Waivex, Xenos and Moni all have poor air foils for motor gliding or L/D efficiency.
