Gordon,
We are lucky or fortunate here in the states or at least I am. K1 is available around the corner at the local gas, sorry petrol station, and is just $2.89 a gallon. I have four fying fields with asphalt within a 1/2 hour drive and access to a full scale runway with zero traffic within 1 hour. I still like the "clean" flying edf offers and I think those that argue about which is cheaper, which I am not doing with you is a mute point. I could have quite a few battery packs for what I spent on my Turbine/composite plane combination. As you know I converted the Yellow F4 which is a fantastic flyer and a nice size model. A local fellow bought it from me shortly after the intial flight. I will most likely build another this winter but time will tell for certain. There is nothing quite like the rush of flying my Jepe F-16 on 1100+ watts and yet it still lands like a trainer.
Regards,
Bob
@ Bob: I agree with you on batteries and prices. The motors and fan units last for ever, so all we need is for lipos to drop in price to nickel levels, and it'll be much better. Regarding numbers of flights per session, I've been taking six 6s packs along to fly my 90mm EDFs which use 6s, and getting 8 flights with a couple of re-charges, so have been reasonably happy with that. Twenty turbine flights indicates that you must have a vehicle big enough to carry two 5-gallon drums of fuel!! Over here that'd be £50 in kerosene, but Jet A1 would be 60% of that cost - if I didn't have to drive 60 miles to buy it. My car would have problems fitting one 5-gall drum inside along with the model, though I guess a bunch of 1 gall containers in the footwells would work out.
That being said, I'll still lust after a turbine!
Best regards
Gordon
