 I wouldn`t worry about a folding prop. <hr height="1" noshade id="quote"></blockquote id="quote">
I agree with Lee. I've flown a Zagi-like plane for a few years, and the only problem with breaking a prop has been unexpected power-on landings. With no compression stroke, they bump easily out of the way by the ground. As long as the power is off [:I].

Ask a question and recieve an answer, I love this stuff.

Lee, the Maxxprod.com site lists a Himax 3615-2100 and a 3615-3200. Is the 2300 an updated (or older) version of one of these? Which of these two (or where can if find the 2300) would you recomend?

Got the wing finished with the nacelles mounted and put the tail feathers on it last night. I love it when a plane comes together.

Weight at this stage is

I did end up putting spars in the wing. The spars are hollow carbon fiber arrow shafts that weigh .4oz apiece. $3.15 apiece at Academy sports.

This shows the wing saddle which ended up with a really flush fit because the top of the wing was left flat where it meets with the fuselage. Heck of alot easier than trying to shape the fuselage to the airfoil.

Mike, sorry, it is a 3615-2100 not a 2300. My mistake. I have a 3618-2300 also. It would work for SSC speeds but is 1.5oz heavier and draws a few more watts to make the needed horsepower.

I think that the 3615-2100 is a good way to go for an electric twin. I have a couple of flights on my 2548 legal Me 410 and the power output is right on. I need to make a new fuse for it though to shave off 3 or 4 oz, and finish the nassel/cowl setup.

Great looking plane Mike!
I tried all the larger prop and gearbox stuff. It actually helped to change the rules and have to work towards a single prop.
June 2004: http://www.rccombat.com/forum/topic.asp?TOPIC_ID=10744

I will be flying (2) 16x2 machine modified motors, wired in series, running through a 1.875 gearbox spinning the 8x3 props. 6s1p battery setup. Current draw is right around 30 amps with under load voltage of ~19.6V. This is the same brushed setup I am running in SSC x 2.

I would go with the setup Lee is using, whenever I run out of brushed motors! Only advantage to my setup is I only need 1 speed controller as well as no radio battery.

I am also running a single setup with a 12x2 turn motor through a 3:1 gearbox spinning the legal 10x3 APC IC prop. The other nice thing about these setups is the static prop RPM is well below the the max. at launch.

3615-2100 it will be then. Everyone has sworn by the Castle Creations 40A ESC. (Pricey!) Is the 40A what is required for this motor or will a 35 do the job? I don't see myself using the programable function of the ESC. I love to build and all but when it comes to power systems I am an "off the rack" kinda guy.

I did some calculating and the all up weight should be somewhere near 70oz(4.4 lbs) which will keep it legal for 2548 and 2610.

35 is enough for 17,5k on the 8/3. On 3s the motor will pull about 30A static, I`d recomend batteries rated for 12C continuous and at least 3000mah. RCLipos.com sells a Polyquest 2s3100 for $38. He only has 2S in stock right now, but has told me that he has 3s and 4s packs on the way.
