What happened to the P1B-1 ?


Hmmmm , In deed .....

Ok the problem with the P1B-1 ...

The folding prop was the problem ..

A) The prop weighs too much
B) RPM and torque roll are effected by the heavy prop
C) Props hangs or folds , changes CG
D) The folding prop is a nasty cheap affair ...

So after a while I realized the folding prop was the problem and the model was hung up as an ornament .

The other day one of my FF models with a timed electrical system fell onto the floor .... Ding Ding !
And a idea flashed into my brain ...
For over a year I have been wondering what to do with the P1B-1 , mostly geared around some form of RC .
But what if I could ? Fit one of these timed electrical power systems ...

The battery fits in the tube , the timer / switch fits in the tube ..
I 3D printed a motor mount for the pusher set up .
The P1B-1 glides amazing without that brick of a factory prop .
The power system has been tested in doors , but not out doors ( very windy ) + the mod is barely 24 hours old .
It looks promising !

I was lucky , the 3D printed mount came out perfect 1st time out .
The motor is a 7mm DIA and the system uses a Lipo battery that is USB charged VIA the timer .
There is not enough power to pull vertical , but horizontal should be fine ..
Hopefully be some fun , especially as the rubber powered factory set up was a PITA .

What I need now !
Is to 3D print a nose cone that allows me to push the start button ..
My 1st attempt at such was a full fail
