are there any good brushed 3d planes out there?

i need to find a 3d plane with good performance on a brushed motor. i just dont want to get a brushless motor yet. what would the best setup for it be. i would also like to be able to fly in medium to high winds (10-15 mph). thanx

the 3dx etc. from www.foamyfactory.com all 3d well on brushed GWS eps300C or eps350c motor/gearbox with the "D" gear ratio (6.6:1). these are made from FF foam or depron and u just download plans from the site for free. I don't know how well they handle the wind as I don't have one but i have read lots of good stuff about them.
What batteries are u thinking of getting (how much money u got ) ?
These eps300 motor/gb drives from GWS are definately the best brushed motor for doing 3d and are very cheap.

Blythe, i have about $250 to burn. i was going to get a miss june but i havent heard any glowing reports from people flying it with a brushed motor. i just went to their website but i noticed that they have a flat-plate wing. does anyone know if there will be a noticable difference between a plane with a flat-plate airfoil and a fat symmetrical?

Fat airfoils do not generally do good real 3D manouvers and would not fly nice in any solid wind. 3D is generally flying beyond that stall point of a wing, with a light plane and a thick wing you dont get to that point easily. If you want a good electric 3D plane go for one with a flat plate. Get a 3DX for a couple of bucks and blow the $250 on a killer power setup. Either brushless or buy alot of 350c's and run them hard on 3s lipos. The brushed motors wont last too long but disrespect is the key to 3D.

One of the Ultimate bipedesigns is maybe even better, less wingloading with them..
Erik Johanssen's free Pulse design looks good
I'm gonna try both

The 3DX will NOT be happy in 10-15mph winds. I cannot think of any small 3D model that will.. I flew my Diablotin in 15mph winds, gusting to 25, and although I had no "problems", it was no fun..

Missed that part,
Andy is right, all the light Depron 3D models are not suited for flying in that kind of wind..
Maybe a GWS Formosa or better the heavier 1 meter span 3D models will do

a GWS350C-D on 3S Li-Po's with either a 12x6 or 11x4.7 will fly an MJ, but i'm not sure how well? and the motor wont
last very long!. I don't understand the resistence to brushless motors?? with a Himax 2015-**** and CC Phoenix10
available at $105 which will give more power, and long outlast the 9 GWS350C's you could buy with the same money

I don't understand either happy harry. Everybody I know that has started into the 3D planes have all spent more money buying a bunch of brushed motors and had more tied up in it in the long run than if they would've just went with a brushless to begin with. Even if you just want to try it out and find it's not your cup of tea, you can always sell a good brushless setup for almost what you gave for it. The guys are telling me that the brushed motors are only lasting between 8-15 flights on 3s. At 2s they are saying they are marginal. The 10-15 mph wind is a problem for anything doing 3D...even a GS gasser! hehe If your starting out in 3D ther wind really makes it tough. Any of the light electric planes are gonna get blown around pretty good in that kind of wind. It's best to wait until near dark or early in the morning if you want to do 3D with a small light electric, or on days when it pretty calm. I just got into this myself, and am very glad I bit the bullet and went with the brushless setup. I know that I won't be replacing motors at all with the setup. I got a Himax 2025-5300 and went 3s2p 1200 Kokam, and 3s2p 1500 Tanic. I got a motor combo deal that came with the motor, CC P25 ESC, and GWS GB for 149 bucks. I did have some Tanic 2200 on BO, but exchanged those for the 1500's as they suited the application better. The FoamyFactory 3D planes are great to start out in 3D with and are very inexpensive to build. The power system is more expensive yes, but it really is cheaper in the long run.

Vortex 3D in the wind

The Vortex 3D from www.flatfoam.com does pretty well in 10-15 mph winds. It's the best one I have for windy conditions. Much better than the Trident, Foamtana or Edge 540. Here is a video Vortex On Windy Day flown in 10-15 mph winds (except the hovering shot we waited for a calm spell). At 25 seconds into the video, the plane is torque rolling while blowing down the runway. At 40 sec., some knife edge hovering and at 50 sec. some high alpha rolls, etc. etc.

Right now, I only have the Vortex, Edge 540 and Edge 540T in kit form with 6mm depron. I'm thinking of offering the plans only for them (same price as Tim's Yak). I'd appreciate any feedback on that.

In all, I agree that 3D is best done in calm conditions. But you can still have some good fun in the wind.

Top quality kit for those with previous 3D experience. Has been tested on brushed as well as brushless motors.

High Desert 3D

HD3D,HDFISH and the AFTERSHOCK are all good performers on brushed power systems. The AFTERSHOCK is the first flat wing model offered by High Desert 3D. I will soon have videos posted on the website.

T3D II, phenominal performer on 2 cell lipo setups

do you have lipos

this plane has to have lipos to fly excellent, if you build light you can achieve a 1.7:1 thrust to weight ratio

OK you said you have 250 $ to spend..

Yes the flat plat planes fly great.. I have flown my SF in 10-12 mph winds and I found it fun... but I am weird that way..I just dont find that the flat wing design allows for a mix of 3D and standard high speed manuevers so I went back to fat airfoiled planes (Miss June, Flubber)

If I where to recommend a setup and I noticed you where looking at the Miss June (I just maidened mine) and have flown it in 10-12 mph winds...this is what I would get

Rough estimates but pretty close

Miss June $65
solite 2 rolls $20
Himax 2015-4200 $50
Phoenix 10 $50
Etec 3 cell $40

Total $ 225

Fun Value.. priceless.

Hope this helps.

Mike
