Hi Graham

Overlander do a motor 4240/10 890kv this will run on 3s-7s but requires a 12×6 prop and gives 540 watts and you would need a 60amp speed controller.
(you need a larger prop with less cells)

Hi Graham
Have a look at hobbyking web site for turnigy aerodrive motors sk3-3542 1000kv (£32-04) this is 670 watts a bit more than you want but that is on 4s so will be less on 3s. you can also throttle back when in the air and you never know when the extra power will be required. You may have to get a 60amp speed controller but once again look on hobbyking website.
There is also ripmax quantum 11 40 brushless motors M-Q2-40 (£39-99) with a 60amp speed controller but this is on 4s .
I suggest you have a search on the various web sites

Hi Ian

I believe that when conversion takes place dihedral is reduced by 50% but it depends on whether the model is high wing or low wing.
The dihedral of a wing determines the amount of self-correction capability an aircraft has in the roll axis.
More dihedral allows more self-correction at the expense of less lift, more drag and less axial rolls. Nevertheless, dihedral is sometimes necessary and is especially important for trainer aircraft.
Aircraft designs having no ailerons need dihedral in order to turn using only the rudder.
An aircraft that has no ailerons and no dihedral will tend to yaw and skid through rudder turns. Some dihedral is always required for rudder only aircraft models.
It is sometimes necessary to change the dihedral of an aerobatic design to rid the aircraft of undesirable traits such as rolling when rudder is applied (roll coupling)

If you have the RG411 in your parkzone glider and its been in thermals then perhaps the info about that receiver is a bit miss leading
but in a bigger heavier model i would still go with the RG631 as it has basically dual receivers eg: main and satellite

Hi Graham
No you need the rg631b as this is full range
The rg411b is only classed as a park flyer which is not full range
Electric motor and esc you need the equivalent of an sc40 which you should be able to find on the interwebby thing

Those servo’s should be ok
With regard to the two voltages those servo’s run on both what you normally find is at 4.8v they have a slower time and less torque than if they are running on 6.0v
How old are these servo’s???
If in doubt change them for hitec HS311 as they are £37-00 for 4 from the servo shop
maybe cheaper at other retailers???

Hi Ian

Ian is correct as you only want one ESC feeding your Rx make sure all plugs are orientated correctly and there should be no reason why it should not work.

Hi Paul
Having no problems logging in either the web site or the forums maybe at club night this could be explained before the talk.
