Coax choppers will always turn one way better than the other, it's just their nature.

The tail trim does appear to only be adjustable when the heli is powered up.
Trimming the tail is something...

1. Cut off may be 3.2, but the voltage changes under load. At rest it may be higher, under load it may have dipped to the cut off. Are the flight times short?

2. Are you sure the brass bushings...

I guess the plug polarity was right out of the box? or did you have to change them. 5mm longer and 150mah more sounds good, did the flight time change?

Like many I have been a little disappointed with the forward flight ability of the DR-1. Looking closely at other similar models (hubsan H203) I noticed that the cyclic control servos were reversed...

If you stand back a look at the industry you will see that there are no standard controllers or 2.4Ghz tech.
Horizon hobby owns spektrum and e-flight so that's why it appears "standard"

I'm thinking they're working on a bigger/better Spartan

Dr-1 with the Xtreme racing frame set.

The pieces weigh about half of the stock...

shutterm4: I doubt that a transmitter reset will help the issue. I told PeterV these stability issues were going to happen and after seeing how they come out of the box I'm not surprised.

P.M.: ...

Different product, the Traxxas radio only uses the left(throttle/rudder) stick to enter/cycle through the menus and the right(elevator/aileron) to toggle into expert rates. The model itself has to...

It sounds like you're confusing binding with calibration. The blinking red from the box shows no link from the transmitter. Binding is a link between the transmitter and the receiver, Outlined in...

+1 on the x642 being too large and the P215 as a great replacement for the stock plastic

The batteries need breaking in. It's like nitro motors, take it easy on break in and it will serve you for a good long time. There should have been an info sheet on the batteries, mine was taped on...

I'm having the same issue with the same packs, almost the exact same. The charger is taking a few cycles to try and balance the cells out. They need properly cycled through the truck a few times to...

Yes, it can be done.
(this is a Summit, so the one motor is spinning in reverse)...

Yes it looks cool. I've tried them and the don't really affect performance. What does tend to happen though is that they will loosen unless you loctite them often, good way to end up dead in the...

Yep, I've been running them and they work very well.
I have the 3s 5000mah and they have good power with the stock system. I would recommend following Traxxas's break-in at the 50% throttle...

The biggest cause or torque rolling that I have found is the misalignment of the drive line. The source of the problem is the amount of play the strut has on the transom.
I would loosen the set...

3.3-3.0 volts per cell is the usual average. It will change under load though. 10.73v is good, you don't have to discharge them any further.

I'm also a bit leery on the C rating for a boat. I think the were intended for cars first, there are rumors that they may come out with better ones later.
The packs the are constructed 3s2p (3...

I've run a P225 on 4s using 2x Team Orion 2s 5400mah 40C and the packs do get warm, but not hot.
The amps load with the new castle motor is around 110A.
I don't have the new esc so maybe they...

Sometimes the servo can be the culprit if it's damp. Leave the receiver box open for a day to let it air out and try unplugging the servo.

Then the receiver must be damp or damaged. Take it out of the box and see if it got wet.

I'm not sure why this old thread got resurrected. :rolleyes:
This was started in reference to the old V1 system that had no business pushing a hull of this size for more than 4min.
Added cooling...

I ran an X440 and the amp load was around 140A and I felt that it made the boat act a little strange with my setup.

I keep coming back to the P215 on 6s as it seems like the best balance for the...
