Default RE: Defiant Model 74 Flight problems

Wil,

I did all the calculations from the link to the canard calculator in this post. The "new" CG location is only 1" from the LE of the wing, instead of the plans called out ~4.1".

I could not get my model to fly with added weight in the tail...like you are doing. Maybe you will have better luck. I have 2 OS70 4 cycle engines in mine. Did you do with 2 cycle? If so which kind?

I am so glad to have another builder on here! Let's keep this thread going...we can help each other....I've already had 2 crashes on mine, hopefully my information can prevent you from going through the same frustration. Another thing is that these canard planes need a lot more ground roll to get in the air. I'm going off a grass field...I'm wondering if these airplane designs are better on a asphalt strip? Anyhow, I'm keeping tabs on this.

My plan of attack is to rebalance at the "new" CG from the calculator above and try another flight. AFTER I'm done with the minor repairs!
