I think all is working again now. Please leave a comment on a photo somewhere if something you need is not working still.

The first time I used it I was surprised by the coordination required to hold the prop and the model on the floor with one hand, pull the lanyard with the other hand, and release the model before the rotor lost speed. At my age, amazingly, I still can get down on the floor and do this! However, the next one I build will have the pulley on top of the rotor head. rgood, Comment for image # 40160 30 Apr 18 11:38 This is a "first"? (It is for me) Very different. Super. Don C, Comment for image # 40160 30 Apr 18 09:56 I agree with DD. Pretty cool little machine! David Duckett, Comment for image # 40160 30 Apr 18 09:19 Not sure why you would be embarrassed, surely no one else there has achieved such a flight:-) hjlittman, Image # 40160 29 Apr 18 13:39 This is one of my Bostillation prototypes that I modified into an autogyro by adding a rotor mast in place of the wing. I did this for the Don Martin Cup contest for rubber powered rotary wing models and ornithopters on April 27. It does fly but on one flight it flew half way across the gym, pitched up, stalled (Yes,model autogyros can stall.) and fell to the floor on its back without breaking the rotor. Then, since the flight started with 2500 turns on the motor, it swept around the gym floor for nearly a minute like a berserk, propeller driven floor polisher. Worse still, Dave Gee videoed the flight! Despite the embarrassment, if I get a copy of it I will post it. hjlittman, Image # 37157 15 Nov 16 21:45 All my new box fuelage designs have an almost self-aligning design that uses laser cut parts and some aligning tools that are part of the kit. The evaluation kits that I sent out have gotten good reviews and they are starting to sell. Of course, I really expect things will get interesting when I finally get the P-6E into kit. hjlittman, Image # 37155 15 Nov 16 21:37 Last year I designed what I thought looked like a proper Bostillation.Turned out to be so popular that I put it into kit this year. The Irish Jumping Bean will be in kit before the end of the year also. I have another Bostonian design up my sleeve, but I'll surprise you with that.
