Mike,
I've been thru a couple of them, both old & newer (second generation) kits. I'll dig in the shop for a manual for correct throws tomorrow & post them if someone else doesn't jump in first.

The original had a Dubro tank mounted above the nosegear retract on the plate & a hopper tank back by the engine. Worked OK, but saddle tanks seemed to work better. I converted one to Sullivan saddles but had to move the formers some to accomodate them if I recall correctly. One of the "necessary" mod's is to open up a hole in the inlet ducting just in front of the engine so that extra air can be drawn through the nosegear cutout. Substantially shortens the takeoff run. I believe the later models had a larger intake area so this wasn't required. Area should be about 2" or so, and was covered in a builder addendum.

The sport wing performs well, the scale wing was, ummm...... "quick" to say the least! Keep the speed up in turns & especially on landing until you get used to it. They fly on rails when fast, but can bite you when slowed down. Split flaps looked good, but I really didn't see a need for them & they didn't do too much on takeoff or landing for me. I'd keep 'em off to keep the weight down.

Enjoy your Scooter!

Bob
