Hi Ian
Writing in theoretical terms only, as I have no experience of an electric vehicle able to tow a glider. Damage to grass is a primary concern at Keepit except in years when we have extensive rain (about every 10 years). Damage to grass is directly related to the tyre pressures necessary to support the weight of the vehicle and rider. I have never heard anyone suggest that the weight of batteries + electric engine is less than the weight of an equivalent powered internal combustion engine. Please tell me if there is such a vehicle? Otherwise it is just an esoteric discussion with no particular purpose in mind.

Subject: [Aus-soaring] Electric replacement for quad bikes around airfields All & Simon I hear Simon H is an electric powered vehicle expert (Solar Challenge Darwin to Adelaide) and wondering if you can offer thoughts on suitable electric vehicle which could be used around airfield and towing gliders. I am sure within a few years it will be the standard vehicle for airport use. Recently at Bathurst I noticed an electric skate board for personal transport to the launch point - now just need a larger glider towing version!!! Off topic I have heard overseas insurance companies may consider you are not covered for damage to a glider when towing behind a vehicle. May be a good reason for driving very slowly when towing glider as just maybe you may not be covered (esp if using other than factory gear). 18 months ago I heard about a Libelle Written Off!! being towed behind vehicle and many many gliders with about $5000 damage from towing behind a vehicle .
