Hi All,
Today I fly this model and she flu very well. following is the observations
1.   Dihedral is High ( 2.75 Inch)
2.   Before coloring , the model was balanced by two small weights ( apx 30 gms) ,but this time needs more weights ( 60 -80 gms )
3.   Motor ( Aeo Lian 3542 – 125o KV ) seems as a very powerful motor for this weight  ( apx1120 gms ) , any suggestion for new motor ?
4.          Cown Has to rebuild with Ply support, Depron Nut Support was brocken at the time of tightening the Nut.
For problem 2 and 3 , pl provide me your valuable inputs to correct the issues.

HI All,

Pl advise , that can I use Emax 2215/09 ( 312 Watt )  Motor on this SAPD, because the Aeolian 3542 – 1150 Kv Motor is  powerful for this SAPD.

Thanks Kalyan Bhai for your suggetions,

Actually , I have Emax 2215 ( 313 watts ) already in my stock, so pl suggest, that I can use it on this spad?

Vipin : Yes , you can learn in Bhopal , you may contact me on my cell no and i dont know any hobbyist from sagar.

Wattage is not the only thing. Don't go beyond 1200-1300 KV. Use matched prop.
Or you may just change the prop of existing 3542. Or use 3S instead of 4S battery to reduce power. May check 8"x4" or 9"x3.8" prop.

Replacing the motor will reduce nose weight and battery replacement will also shift CG.
Adjust of CG is to be done also. Better Adjust CG by shifting Wing Assembly than adding weight.

WHere do we fold the wings as in the diagrams?how much mm of coro to be used to reinforce the wings inside?please help .i ve cut out wing part from sheets as shown in plans by vc . but confused on how to fold it?where to fold it?how much mm to reinforce(the one used inside wings)?please help.

Hi Kartik,
For Wing Spur- I used wood spur ( 1 inch wide and 3-4 mm thick, 48 inch long) and screwed with ply dihedral . Also you can make wing spur from 4 mm coro  , but you should make at least 3 spur and glue together.

For wood spur - You can use wood measurement scale or wood beeding available with carpenters.

To Fold the wing – fold the wing from centre line and make crease by using a blunt edge.

thank u so much man.u r great!
