Baby Lightning Streak Electric from Brodak
« on: April 14, 2014, 09:51:36 PM »
Day two of building the Baby Lightning Streak in between messing with finishing my Prowler and breaking in an engine. My first electric too. Now I can fly this near my house and practice up. Got the kit from Brodak. Love that it was complete as electric is new to me and I am working on sussing it out.
So fun to build this though my mitts have been rough on it a time or two)))))

Thanks....me too))))) I forgot how many steps there were in modeling. Used the silkspan on the wings for the first time....still dubious.
Feels fragile.
Got it primed so as soon as some chores around home and work gigs are done I'll get back to finish. I hope.

Whoooooo Buddy)))))))

Hi Shug,

Like as has been stated in some other threads, no need to prime the open bays.  Use clear dope to seal it and save a good bit of weight.

That silspan felt so flimsy....my first time working with it.  Sanded most of it off. May me a tad more weighty but that electric motor feels powerful on a bench.  Thanks  for the great advice Bill.

Well.....I went and tore the silkspan off. Will use some Monocote on the wings. Needed to fix a rib anyway that I man-handled)))))

Poly-Span is much tougher than silk span and tightens with mild heat.  However I prefer Monocote on "just for fun" airplanes.  It is fast, light, and easy to repair.  Clear packing tape works great as a field repair.

May try that polyspan someday. But will use monocote on the wings and paint the fuse.....strap on the electric motor and bits and get in the air)))))

Pretty much got the BLS finished up. I have an electric motor kit that worked on the bench test and put it on the plane today and first it ran backwards then would just go into constant beeps. I checked all connections, checked that Lipos were fully charged but having no luck so far. Scratching my head on this)))))))
Got some 42' x .008 lines all ready. Stooge set. Now to figure this out. Will post something in the Electric Section.

Swap any two of the three motor leads to reverse the motor rotation.  The instructions sheet(s) should explain on how to match the speed controller to the  timer.  The speed controller is probably beeping because it is looking for a OFF single from the timer to arm itself.   A safety feature so the motor doesn't start to run before you are ready.  Most speed controllers can be tough what the timer calls an off signal.   If you have a good LHS that does electric RC they may can help get it set up.

Ps Your Monocote looks amazing!!   H^^  #^

Yup,that is one sweet looking ship. What does it weigh with battery? To get acceptable performance on my Baby Flite Streak, I had to add working flaps.
Think S.M.A.L.L. y'all and, it's all good, CL, FF and RC!

It took me a bit but I got it all set and ready. Brodak sent me a new timer and now that I messed up everything....and then re-programmed it all I have a good feel on how the electric gear works.
Thanks on the finish.
Now...waiting for a less blowy day to go and fly. Stooge ready.

I have not weighed but I shall. Flaps! Bet that does really get 'er looping. I really built this to just get back on the circle and fly near the house.
Did you add flaps after the build or during.
Whoooooo Buddy)))))))

After. I ran a link from the center of the elevator pushrod forward to the flap horn. An easy retrofit technique!

It weighs 7 ounces without battery and 8.5 with battery. Loving the flap idea!

Wow...that is terrific.....thanks for the picture. What did you use for the hinging if I may inquire?

The hinges are Spectra fishing line, but any thread will actually do. Just never use monofilament line, it is too springy.

Thank you. I am going to fly it first without flaps then maybe add them after. Been so long that I need to see how I do. Waiting for the weather to co-operate here.

Hey there Larry....did you sew those through the wood? I have my Baby Streak torn apart nor to do the flap job. Flew today for the first time in eons. It was mighty windy. Not sure if flaps would of helped me but I like to think they would.
Man it was fun.
Thank you.

Yes, right through the flap and trailing edge. Figure eight through the gap. I use a t-pin to make the holes first, then follow up with needle and thread. Do a search on sewn hinges for more hints.
