Hi ...I do not know how to weigh it down ...All i did more is installing 2 servos on the rudder instead of one on the bottom of the Fuse...
But it is SO Tail heavy...Well, the weight of Moki with BCM silencer comes around 3.12 pounds, and the DA 50 comes around 4.2( inclusive of, puffa canister, ignition,stand off's etc)...
So i think that it should be ok with DA...
I do have a 3W 70 next to me so i will try to use it in the next 30 min....It is too big though..[&:] Does anybody think that i can use 3W 70 for y weekend flying???

Thanks

Manos
