HiDavid, The slow flying model I would like to add to my collection is realy a new avenue I want to investigate,I will have to look in my RCM&E back issues for the electric storch. I don't feel I could design the likes of it on my own.It's my hope that with slots, slats? Flaps it may be possible to have some authoritve power when needed and as Timbo said the throttle becoming more effective as a contol and not be just like A pico stick which I have got and soon lost interest with. By the way I will be watching for feedback on the Kong Power lip'o from al's models I hope they may bring out a lite version. thanks again David and Timbo Ian
