motor mount glued .i have made motor mount from the board thatt is used by carpenters and photo frame shops to cover back side of frame and glued four nuts with epoxy to tighten the screws and glued motor mount with epoxy and used hot glue on outer side to increase the surface area to have a strong joint

also done kf airfoils i am using kf4 in this plane to handle strong winds also it is my first plane with kf4 so lets see how it works i have used 3mm thermocols sheets on uper and lower part both

harshit batra

magnetic hatch done ihave made my hatch by using cello tape to make hinge on one side and a piece of metal on other to stick to the earth magnets on plane i stick magnets on thermocol by hot glue then cover it with tissue and diluted fevicol
it give a lot strength to the joint do any one know any other method to stick magnets on thermocol i have used hot glue,epoxy,fevicol but none of them works good

Here's my maiden flight video of su37 ,turned in a very bad crash due to my poor piloting skills

K K Iyer

No damage i hope.
Just go easy on the throttle when in trouble.
Maiden flight without your mentor?

harshit batra

yes i flew it without sanjay and girish sir.thinking that i could fly that thing (worse thought).i tried to cut the throttle but it was loosing signal i think and plane directly fall on field with full throttle the cannards and nose is broken now  .here is an another attempt to fly before that crash


harshit batra

is the video before sufficient for the proof of flying?

K K Iyer

Landing under control also required, i think!
