3 Blade EP Propeller 15×8 / 381×204mm
Just received my 3 bladed prop shipment today and I immediately tried it out on my Yak-55. I spent approx. 20-30 mins shaving 2 of the 3 blades to obtain a balanced blade since it ain’t perfect out of the factory.
I hooked up the WATTS UP meter and recorded the following readings. Specs as per below:
- SWANG 480Kv Brushless Motor + 80A 5A BEC ESC 158U
- RHINO Battery 3700mAH 5S1P 20C
- 3 Blade EP Propeller 15×8
Max Amp: 57.74
Wp: 1110.9
Wh: 1.5
Vm: 19.13
Specs look ok for the system so will test out the flying performance soon!

Have you ever felt frustrated when you’re happily surfing on 3G or 3G+ and suddenly it switches to Edge? How can that be when you’re not even moving between cells? Well apparantly according to Samsung experts, the phone automatically selects the strongest signal and switches to that (even if that means switching to a suckier connection).
Well I’ve managed to find on the internet how to FORCE your phone to lock onto the 3G connection no matter the signal strength. If you feel the need to do the same, please read on for the instructions:
You CAN force 3G preference for your phone.
- dial *#1546792*#
- don’t press the call button, it will automatically take you to the Admin Settings.
- select ‘3 Network & Call Settings’
- select ‘Network Order’
- select ‘WCDMA first’
- press Done
- press the End Call Button
For those of you interested in getting 3G all the time if possible (up to the lowest possible signal) while maintaining GSM as a backend if in case you don’t have any signal, simply leave the Network Mode to auto and then change the Network Order to WCDMA first in order to prioritize WCDMA regardless of signal strength.
Note: The information provided here is to be used at your own risk and I take no responsibility for this information. No need to worry though because I have done the above to my phone and so far the connection has remained at 3G & 3G+ without dropping to E (Edge).

I’ve managed to fix my tail wag issue on my T-Rex 250. Thought I’d share it with those of you who are looking for a solution.
I basically did the following:
1) I made my own “chinese weights” for the tail by using the nut ends of EZ Connectors and putting them through longer screws used to secure the tail blades. With the Nuts as added weight, it perfectly balanced the tennis raquet effect of the unweighted tail grips. After making adjustment, I was able to move the tail pitch slider (with or without the tail blades) easily without much force and when I let go of the pushrod, it would stay in place instead of move back to the center. The basically cures the high-torque needed to move the original tail slider due to design flaws.
2) I substituted the Align DS420 with a DS520 servo. I’m not sure if the 520 is needed after my fix above since I made the changes at the same time but the 520 definitely packs a bigger punch in terms of torque delivered to the tail slider.
As a result of the above changes, My GYRO Sensitivity which was previously at 60% is now up to 70%. I am probably also able to move it up to 75% without getting much wag but since I have changed my pinion from 15T to 16T now, I had to dial it back a little to prevent tail wag.
The Heli now feels locked in. I have yet to test full collective climb outs but I have a feeling the tail will hold this time round. Here’s to having more enjoyable flights rather than an expensive paper weight 
I’ve also ordered a set of new tail grips from Align which comes with the counter weights. I’ll put them on to see if they perform as well as my mod but I doubt it since I’ve seen a video on YouTube which shows that the weights on the new tail grips are still not heavy enough to counter the tennis raquet effect. We shall see…
UPDATE – 4 July 2009 : I’ve installed the new tail grips from Align (which comes with the larger screw heads – thus new allen screwdriver is needed), and true enough, the weights on them does not make a big enough difference. As such I decided to put on my mod onto the tail which seems to even improve it more. Pls refer to the pictures below to see how I’ve done it.
Basically the new tail from Align and the weighted nuts did the job of curing the tail issue. When spooled up, I can move the tail freely with hand and if I leave it at any spot, it does not move or spring back to any position. Having said that, I’ve left the DS520 on the tail because that seems to deliver more power than the DS420 which in my opinion is a little on the weak side. Good Luck Guys
