I picked up a like new BOT ARF with radio and was wondering if any washout is required.
It seems to be balanced 3 7/8 " back from LE. I weighed it at 58 oz. Any flying tips? Thanks, David

They fly great. Use a Hi start. Anticipate turn response time and plan ahead. Don't land downwind. Drink plenty of water, and try to stay in the shade....

Only grease it in for a landing, the fiberglass just behind the training edge is THIN and will crack no doubt after a couple less than perfect landings. It flies nice but they probably still haven't fixed the bad wing structure. Basic Chinese crap.

Dear Mirage 1

I have been flying my original BOT for 15 years and most definitely you need washout. If not there will be some interesting behaviour on launch:eek:

Tip stalling with such a narrow tapering tip is always a possibility and I used to have to reset my washout every now and again when the covering stretched [it was Solatex fabric on an all balsa/spruce structure]. As the covering relaxed the tip stall would manifest itself with a moderate yaw on launch. The stall was controlled by a sharb dab of down which re-established airspeed.

I would set my inner panels with about 3mm and the outer at about 6mm.

Don't need it if built to plans. Tips go semi symmetrical when sanded as per instructions. Plane will generally stall straight w/o tips dropping other than slow downwind turns and almost anything will stall that way.

Dave's original hand drawn plans have the washout in the last six to eight inches.

Built mine from plan. Got it rediculously light (needed ballast to make it competition legal until I recovered it in something stronger and heavier) but never did put washout in.
Flew/flies great, slow flat turns, sharp steeper ones, stress free, hands off thermaling at its best.
