Parkzone Sukhoi Mods: Paint, Battery Upgrade, GWS props

Sukhoi: Krylon H2O Yellow Spray

Added a very light, simple coat of Krylon H2o paint to the Parkzone Sukhoi. It greatly adds to the visibility while flying and looks great while in flight. I also put on the other GWS prop I purchased which adds additional speed.  A minor mod I also did was to remove the crap velcro on the Parkzone batteries. The velcro hooks weren’t as long and didn’t have enough grip as the 3M Scotchmate Hook and Loop Velcro I routinely use , the battery no longer drops from the plane in flight and was a quick 30sec mod.

The GWS prop 5043 is now installed and flies great. I was using the GWS 5030 which is also better than the stock Parkzone prop and is the orange colored one in the other photos. They are both great props the have better performance and clearance. Remember that when using these GWS props you need an adapter for the prop to fit on the 1.5mm prop shaft. I am using GWS part no. gw/spnoo1 (package of 6, but only 2 can be used 1.5mm) there are also other adapters on the market but I like the spnoo1 as it protects the prop in case of a nose over.

My new batteries, the Hyperion 1s 240Mah arrived a short while ago. I haven’t installed them yet because I’ve changed my mind on the adapters I will be using. The JST connections that I have are larger then what I want to use so I had to place an order for a couple other connectors that I will experiment with.

UPDATE

** I have used all the battery connections below and in my opinion the hands down WINNER is the .8mm Gold connectors from Hobbyking! They are the most secure, easiest to connect and remove, and have a larger contact area which translates to more efficiency for current. Another advantage is it’s a easy install using .o38 solder. A lot easier then the molex connections. **

Bullet Connectors FTW!

The main problem I discovered is that you can’t easily purchase the battery side connector that is on the Parkzone micro airplanes and E-Flite micro heli’s. The local hobbystore has the receiver side (male) plug but Parkzone doesn’t sell the female connection. Hell, there isn’t anyone yet who can agree what to call the connectors but here is what I have learned.

The owners at various forums are using either different connectors all together or splitting THIS  extension from HobbyKing to make theirs just like the stock connection. Another option at Hobbyking being used by RemE (member RCGroups) and now myself,  is .8mm Gold connectors from Hobbyking. You can see pictures of his battery upgrade configurations HERE . These .8mm gold connectors are currently on my batteries (pictures above on my 240mah hyperion 1s lipo’s)

Hobbyking Micro Extensions

I finally located what I was searching all over the hobby stores and the Internet for! The Parkzone Sukhoi and Mustang Ultra Micro Airplanes use the following on the battery connection. This is the $320 crimp they want you to use! You should be able to use the the crimp common on most wire strippers as a less expensive alternative to the $320 Molex crimper. Make sure the connection is SOLID!

**Trying to crimp and solder your own connections with these small Picoblade molex connections can be difficult and if done incorrectly can cause damage. If you intend to use the same stock molex connections look into the Hobbyking connections or switch to adapters that you are comfortable with.

More Molex Picoblade info here:

PicoBlade™ 51021 (1.25mm)

  • Connector Type – Receptacle
  • Contact Type – Female Socket
  • Number of Positions –  2
  • Pitch – 0.049″ (1.25mm)
  • Number of Rows – 1

You then need to add a crimp onto the bare wire and then install in the housing above. The Digikey technician suggested the following crimp to finish the connection:

* another source for battery side connections through ALL-Battery.com HERE, they are more expensive then the HobbyKing connections though.

If you want to avoid having to solder any connections and would like increased flight times than you can always purchase the Turnigy 160mAh 1S 30C batteries. They’re about $3 and have increased capacity as well as a higher discharge rate. These batteries sell out fast and the quickest way to receive them is by backorder at the moment.
