I converted my EasyStar with the intention of adding a video platform. After a bit of calculation a selection of motor (Scorpian 2215-18 plus 25amp ESC) was made and prop. Turned out the prop we used was hell for the EasyStar. The torc of the 10x3.8 was problematic and the same can be said of the 9x3.8 we then tried causing the EasyStar to be really difficult to control on take off. Fitting a 7x5 proved way better and put the "easy" back into Easy Star.
Adding some 5 oz of plasticine to cover the weight of the camera unit and adding a 2 oz plasticine counter weight on the tail the EasyStar flew really well even in a 6 to 7mph wind. Prior to adding the weight the plane weighed 1lb 15 oz.
The EasyStar has had some bumps during my training period and has been named "Phoenix" due to the amount of glue and additional sticky backed plastic holding it all together.
An OSD device I have will be tested when I'm ready. I will need to carry out a similar weight check and then I may consider an slightly larger prop. My thanks to my friend Colin who's help in this has been super.

Hiya guys - I'm a long-time flyer of EZ*'s, a great plane as stcok, but I think the 'perfect' motor for it is the HiMark 2816 or similar with an7 x 5 prop....an excellent comb. Verticals all the time but controleable on a 2200 2S (yes, 2S). And flight times of 30 minutes easily. But a bigger rudder always helps!!!!
