I used to spend time reinforcing cowls. Now just simple packing tape with the glass fibers running through it placed mainly on the bottom and crossed. One previous set up stood up to nose in serious enough to break a pwr 15 motor shaft. explode the motor mount, break the hatch in half and shorten the nose, strip the E&R servos and pull out both wings. Too bad it was a crash virgin unit. This was over the E control horn failing. I tried Chicken Sashimi's and other ideas. This was quick and works. Oh the cowl in that crash lost a 1/2" chunk part of a cylinder. Start with packing tape ( Must have string in it) Lay it in a criss cross pattern all around. Lay in gorilla glue in layers. At each lift wet it with water. If I felt the need to do that again I would use Great Stuff foam. That cowl can still be used, But I prefer a more neutral CG these days. Not all of my landings are greased, but I do no feel the need! Chris |

Reamed with #11. At first could not get it past threads and used a wire stripper/cutter a bigger dia then the rod. This shattered the CF. Dipped in accelerator and a little ca fixed that. The cheapo HF diamond wheel made clean work of it when off the rod! My wife uses CF shafts in archery. I got a dedicated cutter which has some kind of abrasive/ resin wheel. Of note the health warnings that come with arrow shafts are scary! Chris |

It does every thing I want it to. T is smooth end to end. Flight times are good and yes vertical! I have been wanting to try an 11X5.5E but 11 is probably pushing it for a belly lander. Of note it is worth the time to balance props. Chris |

oh there wont be an awful lot in it, those two props have similar top speeds, you will probably find the bigger prop will accelerate faster, but chew more amps. you might like to buy a 9x9 also.

You may have to use T management with that big one. Figure your kv on 10V over your flight. So 11000 rpm. From my pitch speed nomograph. 9 reads 118 mph 8. 101 7. 90 6. 80 5.5. 65 You will not get these pure speeds. With the 7 my power 10 Cat may get 60. But as long as I get get out of trouble, vertical power, I am happy Chris |

Droid would not let me get the smiley in were wanted. I did in fact try an 11X5.5 Wildcat was slow and flight times were short. Vertical was there. Over a year later bet it will harrier with one! Chris |
