Check out the new line of Flat Foam Fighters for RC combat or fun flying at www.montanamodelworks.com (http://www.montanamodelworks.com). There are several WWII designs along with biplanes and twins. Download the free workbench plan while you're there. This is a great addition to the fine selection of park flyer designs.

Scott,

Those look very nice. Thanks for posting the link. Maybe a klutz like me can even enjoy one of those. :)

Any thoughts on using Depron instead of FFF for these?

Thanks for the reply. I have not tried Depron, mainly because of low cost and the availability of the Blue Core. My intent is to make these as easy as possible to build for the lowest cost because they are intended for combat. They also make great knock-around planes. They're very rugged. One thing I don't like about many foam planes is the way the fuselage twists as you maneuver. These don't, that you can see. I've built lighter examples with other materials. They fly great, but won't hold up for combat. I don't know how stiff Depron is compared to the Fan Fold Foam. These are very rigid using simple balsa strips instead of Carbon (at $4.00 or so per stick). I spend more on the paint than I do on the plane. If you wreck it, t's not a big deal to simply build a new fuselage and reuse the wing & tail. There's enough power to hover with a GWS 400 drive system (inexpensive, low power) & 2s 1240 mAh LiPo.
Thanks again, tell your friends. It really is a blast.

Who do you get your GWS systems from?

Also, I saw gearboxes; what ratio do you like? Is it different for different planes, or are the power systems all pretty much interchangeable?

Thanks for the reply, and I will pass this along to my electric flying club members.

I've had good luck with the EPS-400c with the "D" gear ratio (1:3) and their 1080 prop. They're $12.69 from Tower. If you shop around you may find them a little cheaper. I've also bought these from Todd's Models on close out. The GWS 400 sized speed control is just under $20. The GWS NiMh batteries work ok and are about $10. I have also used the GWS setup with a 1240 mAh, 2s, 15C LiPo and the difference is dramatic despite that it's 1 less volt. It will put out a lot more current. I really recommend the LiPo - more power and about 1 ounce less. I've also used a 100 watt Himax outrunner with a 3s 910 mAh LiPo with excellent results. It has a lot more power than the GWS. It will just shoot straight up. This is the way to go if you want performance and don't plan on combat. I would simply rather risk a $35 setup than a $90 - $100 setup when there is the very real possibility of mid-airs (the risk is minimal, though). If you don't mind risking damage to the brushless, it is much better. It's also easier to convince others to get involved if they can buy a less expensive new system. Electrics are still met with sceptesism at our field. I have a couple other planes that make their jaws drop, though. They have a hard time believing what an electric will do. Once you get past the cost of batteries & chargers, you can't beat it with a stick.

Hope this helps.

Sorry, I forgot to answer part of your question. The motors are very easy to change from one plane to another or swap motors. There's one screw and it pulls off the stick. I have not tried all of the gear ratios. You can change the gears pretty easily, but I don't mess with it. To me, I just buy another complete drive for $12. I have used the 350 sized drives. They cost about the same & weigh about an ounce less. They will also pull the streamer around. Use one if you have some laying around. The 400 size works better, though. It only takes a couple minutes to swap from on to another. The 400 speed controls will also take 9.6 volts where the 350s take 8.4v.

Have you ever looked at www.headsuprc.com (http://www.headsuprc.com) for brushless setups? Much more affordable, I would bet. Jeff has some great stuff, may pair up real nice.

Thanks for the info, I just ordered a set of plans to check them out.

Here's a $30 brushless/lipo set up I'm running on my WWII combat foamie. It works great.

2408-21 with 18amp esc (https://www.unitedhobbies.com/UNITEDHOBBIES/store/uh_viewItem.asp?idProduct=4852)
2s lipo (https://www.unitedhobbies.com/UNITEDHOBBIES/store/uh_viewItem.asp?idProduct=5477)

An APC slow fly 9x6 works best for me. Plenty of speed and power with around 7-8 minutes flight time, pretty much wide open the entire time.

Hmmmmm that looks vaguely familiar, James.....;)

I bet that setup would work well. Those TP motors are gaining quite a good reputation.

Thanks for the order. Let me know your impressions, please. The brushless setup looks great. The price is definitely right.
