Title: my latest homemade RC plane
Post by: aaindthu on September 07, 2018, 11:26:42 AM
The first low wing rc plane I built did not fly and crashed.  So I made this plane.

1) it's a high wing trainer
2) more pics needed
3) do you have plans?

No plans.  I just made it without plans, and fyi I am going to fly it

tomorrow for the first time.   so, I cannot assure you that it will fly, yet, because anything can happen. :-\

Make sure you've got the cg correct. If you mess up the cg, it won't fly.

Beautifully made ..

Proportions are very nice.

I do hope you have a successful first flight

My first plane blu baby crashed in hand launching. Launch your plane without propeller and try to learn hand launch. I missed this part. So, my blu baby crashed.
My blu baby rc plane's landing gear starts bending in take off & I can't fly plane. So, test your landing gear before leaving home.

I will check my landing gear as you said.  Thank you

@aaindthu,
1. Ensure that it balances not more than 25% of chord behind leading edge
2. Use half throttle for test flight launch
3. Hand launch. Level. Neither going up nor down.
4. Avoid giving any control input for first few seconds. Thereafter use minimum control.
5. Check that controls move in the correct direction!

Model looks good.
If you follow the above guidelines, high chances of success in test flight.
Best of luck.

EXCELLENT  {:)}

For tomorrow REDUCE control throws, and REDUCE power to about 75% once you are 5-10 ft high.
Then find the throttle setting for cruise without climb or dive (maybe around 50%). This will allow you to fly without too much tension!

Congratulations on your successful build as well as successful initial flights. Well done.
Regards

thankyou sir.  
I could not do a level-flight as you mentioned.
But could it be because of nose-heaviness perhaps??  
i dont know.

Nice Build!
Landing of rc plane with negative angle of attack will cause crash.
Landing faster is better than crash.

Also, if you have flaps function, then apply flaps down at different angles with simultaneous up elevator  accordingly and check its affect at different slow speeds in combination of proper throttle management.  Perhaps this might help in finding a proper low speed touch downs.
