I saw a large 1/2 scale BD5 made out of depron in RCM&E this month. It was interesting as it was over 2m span and only weighed 11.5lbs. Apparently a similar sized model built in traditional means would have come out at over 100lbs. So I was wondering if anyone has attempted a 2m patternship or similar in this stuff.

My first 2M built up plan from Mark Hunt utilized a depron crutch, depron turtle deck and lower rear deck. The formers were sandwiched 1/32 balsa depron balsa.

Plane weighed 10 lbs 6 oz with OS 160 on pipe, covered in monokote and placed 3rd in Intermediate at NATS.

Jusy need to be careful, depron is denser than contest grade balsa but can be lightened through milling. I used 6mm.

Could it have been built any lighter if a different power plant was used?

Chuck,

Didn't win the concours....but that was a really great flying airplane....someday u should build another one for that OS160.

Sure, if it was designed for electric I think things could have been done differently.

Here is whats been on the board for ...mmm...... 2 yrs.. hard to be motivated sometimes.

Anhedral canalisers? Now I've seen everything.

Ty, I am a leader in Bizarre.... just ask my friends.

Chuck

I AGREE!!!

Ahem... i said FRIENDS.. hahahaha.

Yes, poor Arch had to listem to some of my wild hairbrained ideas... never did get a chance to go thru the diesel converted OS 160 turning a 20X10 prop on a 10lb model.

oh yes, i said DIESEL baby!
