FT Baby Blender. Re Maiden !!

...a super bipe

I had long wanted a bi-plane and, having been bitten by the Flitetest bug, I decided that the Baby Blender would be the one for me.

Having built it and checked the CG I discovered, as I have with a few FT planes, that it was tail heavy and therefore I decided to fly it with a 2200 battery to add weight to the nose.

In addition to now being heavier, for the first time I used an "all-in-one" pack from eBay which, at about the same cost as making the plane, I thought a perfect fit. Unfortunately the Baby Blender turnout out to be pitch sensitive, either going up or down in a hurry with no happy medium achievable.




Also unfortunately, the eBay motor popped after only a few minutes, leaving the overweight bipe to plummet earthwards.

Fast-forwarding several months, I eventually replaced the Blender's motor and also gave it a covered lower cowling, something I'd tested with success on the FT 3D. Also, I decided to go with a lighter 1800 battery and see what happened.

The combination turned out to be a winner, the lighter-weight FT was still stable and now with a much lighter nose it quietly floated around the field once I'd set the elevator trim down a little; it headed for the skies so much lift was it generating!

The only change I made from the first flight was to increase the aileron throws a touch. Apart from that all good, and I'm looking forward to many more flights peacefully punting the little bipe around the oval...
