Will you be going to E-Fest Dan? I'm still debating.

A series of these is a great idea! What's the wingspan?
If you can finish it out at around 2oz it will be a great flying model.

Glenn,

The way it's looking now, I should easily be under 2oz. I cut and assembled the wheelpants, wheels and landing gear fairings last night and put every thing on the scale minus the battery and it's just over 1.0 oz, but not enough to register at 1.1oz.

Wingspan is 19", wing area is about 54sq.in.

I'd like to do a series of these and maybe even make conversions of things like Comet kits or other old rubber powered free flight designs. One of my short list items is to do a conversion of the Guillows Piper Cherokee to use this Power Pack concept.

Hi Zeke,

Looking good. Since making the power pack removeable has to cause some redundant structure, any idea of how much weight it's costing you over a direct installation?

I may try to sneak down there, but with the newborn, It's a very delicate situation with the wife. I have friends that go every year, so I'm sure the pressure will start to mount for me to go along too.

We have a series of indoor fly-ins at a large sports complex here. Something like this would attract immediate attention.

I'm guessing somewhere around 3g by the time you add up the balsa structure and the magnets. I can try and weigh it tonight.

Well...it looks like the maiden of the Monocoupe will be a while off. I had hoped to have it ready to fly at a indoor event this weekend, but due to a really stupid mistake, that won't be happening.

I was using my heat gun to shrink some tubing. I accidentally pointed the heat gun at the AR6400 brick for a couple seconds while my attention was focused elsewhere and...melted the servo cases! The receiver works, but the servo cases are distorted and the teeth on the servo shaft melted slightly. The servo motors work, but the servos are basically dead.

Add expletive here________. Done that before, a replacement servo should do the trick for you. I may have one to send you, but it may not make it in time..let me know, I could always. Check the lhs or overnight you from my stash.

Good news is that the servo mechanics are available. So for $20, I'm getting replacements. I may see if any of the not-so-local hobby shops have the ar6400 bricks in stock...I wouldn't mind getting one of the new bricks with the brushless ESCs.

Zeke,

You'll definitely be filling a hole in the micro RC market. Good going!

You know whats funny, when I was browsing through this thread from beginning to end, and before I got to post 22 I said to myself...."Self, I dunno if putting the heat shrink tubing to attach the control rods directly over the brick is such a good idea". Then, I read post 22 and said..."Self, you were right". :-)

Enough of that...pretty sweet that you can get replacement parts. Keep at it friend!

-Mike

The only way I've found to mess with heat shrink over a brick is by gently touching a soldering iron to it. It's not the easiest method, but it has proven to be fairly effective.

I've already worked out the kit cost ($29.99), I just need to get it finished and test flown before I make any kits available. Then I need to make some assembly instructions.

Kit will include:
Laser cut balsa parts
Front windscreen
Rare earth magnets
CF rod for control rods and wing struts
possibly wire for the landing gear
