GWS War birds on 400's ?

Does using a 400 size motor in GWS Warbirds direct drive work well. I see in the manual it is an option but have never tried it. I am looking for an improvement in flight time and power/speed over the stock geared unit.

What motor 6V or 7.4V? What prop?

Thanks
Charlie

I am sure it would work ok but, the prop would be really small and look pretty fake IMHO. Maybe a 7.2 and a 8 or 9 inch prop??

I flew my GWS P51 with a dd 6v speed 400, 6x4 apc prop,8 cell NiMh 650 and 950. It flew with much better speed than the geared setup, even though the airframe was draggy. Lost it a couple of weeks ago when I took my eyes of it to check the tx. Plane was destroyed but the batts were okay! If I got another, I would go dd again.

I have a couple battery choices. I could use an 8 cell pack of AAA size NiMH 700mAh I think they are or else I could use 2 or 3 cell packs of lith in 1200, 1500 and 2100's

I have several planes but I am thinking of the new spitfire from GWS I just got.

Thanks

GWS 400 upgrade

Use GWS 400 motor/gearboxes. Warbirds like the 3.0/1 ratio. They slide right in. No modifications for F4U or Zero, but mounting stick needs shortening for Spit, Me-109, and P-51 to get fuse/spinners to blend in. Extra weight is O.K. as most people have to add dead weight to nose. APC 8x6 slow for more speed, 9x6 slow for more vertical. Kan or CBP 8 cell 1050s can be squeezed in. Good for 200+ full-throttle flights. If satisfied with 400/gb upgrade, substitute Zagi reverse timed 400 ($10) for 10-20% mor power-but shorter flights. My 400 modified warbirds blow away the 350s and fly like heavy-metal planes should-slow to climb, but come dowhill screaming.

Spit9, the 400 motor/gearbox mod sounds like just the ticket for the spitfire since I've been reading most builders had to add nose weight to balance it right anyway. I would imagine with that big 400 sitting up front wouldn't need much (if any) extra nose weight. True? I've got an old 20 amp ESC and 9.6v 1100 mah battery sitting in a box waiting for a new home. I think they may have found one it a new Spit! I may just have to pick up a GWS Spit glider and 400 mtr/gbx to make a park flying screamer!

Thanks for the tip!

I'd go 400DD with a 6040 or 7035 prop that will scream just fine. The 400 geared down will give more thrust (for faster climbouts) but the DD400 will fly way more scale (even though the prop isnt, LOL).

Kamikazi, can you show you mounted the 400DD in the GWS planes?

Thanks

Direct drive speed 400s like small, 6 or 7 inch props. Most of the warbirds have two mounting holes fot the stick. The lower hole is for the direct drive mount. The mount is just a U shaped piece of plastic which cradles the motor. The motor is held in by rubber bands.

The main problem with direct drive is low end torque. It takes a while for direct drive motors to start pulling and the prop may be stalled until the model is going a certain speed. As long as you're aware of this, you'll be OK.

I fly my GWS Corsair with a geared 400 (D), APC 9x6SF prop, & 3S 1320 lipos. It flies fast and is robust, I have over 100 flights on it and its doing just fine.

I'd either go geared, or brushless if DD, your going to get half the thrust compared to geared and the spitfire flies fast anyways, relative to the corsair or zero. The spit likes weight up front, but it also likes to fly light, so I wouldn't throw in a 9.6v pack of Nimhs in there. Instead,I'd use lipos if you can afford them (allerc.com has a sale on several 3c packs going on now). Make sure you cut the battery bay all, or almost all the way forward or you'll need balast- even with the 400.
