Give it a try, I've noticed a bit of improvement in LIFT, & F-R mobility...give it a try, ya got nuth'n to lose, but a few mins time & some scotch tape.

Nice. Just make sure with anything like that that you keep the weight and length balanced. Along those lines, on my helis, I take that tape and put it on the leading edge, I'm not sure why or how, it protects them a LOT from bangs, wear, rips, etc. You rip up a tenth of a penny (if that) of tape that you have laying around and isn't good for anything anyway, and save probably 2, 3, maybe even 4 sets of blades depending on how often they hit stuff.

Yah...I was thinking that something a little more H-D, like maybe packing tape (NOT reinforced strapping tape) would be good for the leading edge.

 

I like your idea of applying it as a preventative measure...BRILL! Wish I'd thought of that first, but def gonna do it to my set of new spares.

 

It's amazing how good a repair can be done to a chew'd up leading edge with a little smoothing (sanding) & tape applied...almost new.

 

I fly "banzai style" in the cabinet shop, trying to hover over, & land on, light fixtures etc...tha prop wash looks so cool when you hover over a light fixture, with about a decade's worth of old sawdust accumulation on the top...surprised

 

Yeh, I know...it'll eventually fubar my gearz, etc., but hey, after all is said & done, it's a 25 dolla toy...& I'm hav'n more fun than any 50+ should be havin' with his clothes on...wink

OK...just spent the better part of a day off, frittering away my time diddling with my 109G.

Stripped her down to the bare essentials, was amazed that there was almost NO visible sawdust contamination on the insides or gears.

Used some Schwinn factory chain wax to lube the gears & main rotor pivots. This stuff is liquid initially, then dries to a fine powder which they claim doesn't attract dust.

 

Then I took CPD's advice to the next logical (in my mind) step...I wrapped the entire set of main rotors in HD clear packing tape, creasing it around the leading edge for impact protection, & sticking the excess to itself off the trailing edge. After smoothing out any air bubbles, I trimmed the ends with a scissor, then used a straight edge & a sharp knife to trim the trailing edge...leaving about 3/32" overhang to increase the blade width, & in theory, lift.

Now she practically jumps off the floor...& has become an even worser ceiling magnet...cool

 

I haven't flown her enough to notice any decrease in flight time, but am enjoying a bit more lift.

 

EDIT: after flying in the shop today, I've noticed that the lift is stronger 4 sure, as well as forward momentum.

And taping the leading edge is spot on as a preventative measure...thanks for the tip, CPD!

 

EDIT 2: after using a stopwatch to time several flights, I'm averaging 7:30-7:45 mins per charge. Apparently, the extra weight of the tape mods has little effect on flight time.
