If these aren’t the ones he’s referring to, they are close: I’ll continue with mine but a new Viper inspired 250mm race build beckons. How do I start a new “string” for this frame fix? Please repost! Good Luck with your Sky Vipers, folks.

Very Gentle, and full performance restored, even newly realized. Turns out the reduction gear/prop mount was slowly slipping off of the shaft, which was then easy to bend. The kitchen sink slip jaw pliers solved my other problem, power robbing gear lash. Who knew? Learned Hover 35%, down from 53% and it’s quick as a cat now. Really! For an entire charge, even with a bit of breeze/turbulence. My v2450 can now (position) hold completely still. The frame is now as stiff as a new 4mm carbon X race.

How to hold the frame in place to get proper measurements? Bingo! The same way the Sky Viper will fly from now on! $0.45 worth of Spectra kite line carefully wrapped around, and pulling in on the motor lowers completely firms up the frame like a bow and string and brings the motors back into alignment. …so now what? I was measuring for some braces I’m building to try and straighten/stiffen the frame. As a result, I will doubtless avoid injection molded frames in the future… I knew my frame was flexing, getting softer and taking a beating, just not how much this affects every single aspect of performance. The thumbs off GPS position hold drift that becomes an expanding, accelerating helix until the battery dies, impact, or worst of all, attempt to RTL! O.K., you know the drill, try to decend from on high, but it won’t, now it’s rolling and pitching back and forth, oh no (you didn’t know about Acro and sensors either), wham, darn hard landing - or. YOU HAVE GOT TO BE KIDDING ME! Frame fix for less than a dollar! Performance Hack! Go little Viper, go!!! What a great project! That being said, the CrazyPonies are definately a big step in the right direction! That was probably a mistake as those motors will likely bring the SV’s t/w up to an even more acceptable level.

I am starting a new build project and didn’t want to spend the $27.00 plus. In retrospect, I would probably go with the Micro Motor Warehouse 17 or 18k (“insane speed”) motors equipped with long 11t pinion gears (not the MMW versions). The Viper’s personality is so much better with these motors. The leads were too short and they all spun ccw, but after some soldering, I couldnt be happier. Although they sound as if they are not spinning as fast, they appear to have more torque than stock. I found some Crazypony motors for $20.95/8 on eBay. Speaking of motors, the factory jobs are not up to the task for the heavier v2450/2700 and slowly died after less than 2 hours f.t. I tried some Gemfan Wind Dancer 5042’s, they do not generate sufficient thrust and allow the motors to overspin. That setup though, is the fastest, makes a bit more noise and are “wilder” than the Cyclones. They pull too much air and require an 11t pinion to calm the SV down. The Gemfan 5550 3 blade bullnose are hard to come by and expensive ($4.00 p/pair B&H). They are quiet, smooth, fairly fast and have great control authority. Am I going to have to throw a $30.00 set of 17k motors at this thing? Thanks, SEĪloha Brad, I am currently using Dalprop 5544 Cyclone 3 blade props. Again, knowing the design rpm considerations for the motor/propeller on this drone would be most helpful. longevity) and potentially extend flight duration a bit. Dropping to a 13t pinion may be necessary at this point to ease motor load (i.e. Autotune’s 1'-2' bumps become 3'-5' jumps at a cost of about 5%-7% flight duration.

Adding a third blade ended up not being as necessary but still makes for an impressive acceleration upgrade that I am going to stay with (Gemfan 5550 bn3b). “Bullnose” profile props appear to provide all the additional surface area needed to compensate for lower altitude density.

Although top speed is only slightly higher, the drone gets there much quicker. Rate of climb and more importantly controlled decent are similarly improved. Position hold “wander” is reduced by orders of magnitude. Autotune mode shows much less bounce and f/c corrections are more precise. Upgrading to a new prop (one that doesn’t flex?) has helped tremendously. What rpm is the current model using? I believe that I’m seeing 1760rpm a learned hover of 53.17% meaning a maximum motor speed of 17k? Are the actual numbers listed somewhere? Possibly the Micro Motor Warehouse or other 8.5x20mm varieties (that maybe are a bit more economical than $27.00 p/set for the MMW’s?). I have seen the stock setup wind down in as little as 2 hours flight time! I am looking for recommendations on new brushed motor options. For the Sky Viper v2450gps version, anyway, the motors are indeed at their limit.
