Just need a little advice, I have just received my GWS Formosa today and I have a spare Typhoon outrunner 15 motor and kontronic (non lipo) speed controller.
Will this motor (the 15) be okay to use in the Formosa as I don’t really want to start having to buy another motor, I realise the Formosa comes with a motor, but I am sure it wont be up to brushless.

Any help would be greatly appreciated.


Many thanks

Keith

Hi Keith,

the Typhoon 15 should be ok with the Formosa, have seen others on the internet use it and report good flight performance. Be sure to keep weight as low as possibile, as every added gram lowers the performance of electric foam planes. If you can, use lipos instead of NiCd/NiMH cells.

okay I have another question. As i will be using a typhoon outrunner 15 motor on the formosa, i have managed to get a Ply GWS Stick mount so I can attach the motor with hopefully no problems. I have a Kontronic Swing speed controller which I shall be using. as for the battery.

I have a CP1300 mAh 10 cell pack. Will this be too much for it as in weight or what ? I dont want to go to Li-Po's or lithiums on this model as I have the speed controller and its only for Nicad or NiMH and I would like to use this in the model otherwise I consider it a waste of money.

What batteries are you guys using that are NOT Lithium or lipo and also what size prop will go best.


Once again Many thanks for all your input.

Hi Keith,

I use Lipos even with non-Lipo ESC, which sounds kind of funny but is not. You can safely use a 3-cell Lipo on this plane with a non-Lipo ESC (just check your current draw), you will notice a drop in power when your Lipo-Pack is almost empty and that is the signal "time to land". You will have enough time to land safely, don't worry.
The main problem is, that foamies and pattern planes in general fly better if light, lightest. You can use 10 NiMH-cells, but you won't be very happy with the performance. Put Lipos in and the plane will change completely - be sure to follow all the safety precautions!!!
If you still want to use NiMH, I'd go as light as possible and consider buying 10 KAN 1050 (21g per cell, 2/3 A), IMHO the lightest and strongest NiMH cells available for e-flight.

Keep in mind: these planes - as any other pattern plane, too - fly best if they are light, possibly VERY light. Many people ask if the can use standard equipment in small depron foamies. The answer is "yes you can, but will it be funny??" No it won't. Light equipment (such as 6g-servos, 7g-receivers and such) has its cost, that's true, but without it I consider it to be a waste in money and time - it won't be funny at all! That's also true for Lipos.

As for the prop, follow the advice of the manufacturer, he knows best. I think it will be around 9x4,7 or 10x4,7 for 10 cells/3 lipos.

thanks for your reply. A few people are telling me that I should use Li-Po's and use that speed controller, it just worries me a bit, as you hear all stories about li-pos catching fire and having to be careful with them etc. I may go that route, or I may consider getting a KAN pack and trying that route 1st or I may just put the SC on Ebay and flog it and get something 100% suitable.


I dont dispute what your saying, im just worried about bringing a cell under the 3v load, im not 100% up on lipo's yet and my knowledge on them is somewhat limited at the moment.


Kind regards and thanks for your advice, Now i need to get hold of a CC Phoenix 10 SC for my shockie, maybe they will have some at good price at The Nats this w/e

Okay well I have got some things sorted, now need your help urgently lads as I need to get this built in the next 4 days and sorted out for my flying clubs trip north to bonny scotland.

I have got a Typhoon 6 3D motor, a castle creations 10 speed controller. Now I am unsure of what batteries (lipo) to order and what size props. Could you excellent people out there give me some advice for this please as would like to order the packs asap.

Many thanks.


Keith (UK)

just a quick question, I have the formosa started now. I have a typhoon 6 3D with a Castle creations 10 Speed controller, a 1500 3 cell lipo pack (on its way) what size prop and i wont be fitting the landing gear as I fly off of grass. so I would think I would need a folding prop ?


I dont know how to understand what prop sizes you work out to go with this set up.

Many thanks


Keith

The manufacturer states 9x4,3 or 8x4,3 for the Typhoon 6. Sorry I assumed you had the bigger Typhoon 15, which is IMHO more suitable for the Formosa. Try 9x4,3 APC or GWS, a bigger prop might be too much for your lipo cells. If you have the chance to, check the amps of your setup and decide: if the amps at full power are more than what the lipo cell manufacturer states on the pack, then choose a smaller prop.

Have a look at the electric flight forum over [link=http://here]http://www.rcgroups.com/forums/index.php?s=&topic=air-elec[/link] for a lot of comprehensive information about lipos and why you have to be careful when charging them.

Have fun![sm=tongue.gif][sm=thumbup.gif]

I used a Himax 2025-4200 with a GWS C (5.33:1) gearbox, APC 10x7SF prop and Kokam HC1500 3S packs. It has unlimited vertical, top speed is in the high 50mph range and flight times are in the 15 min range with very little throttle control. At full throttle it really isnt a park flyer anymore...lol!

I have all programmable esc's but don;t even use a auto-cut off it cuts off to early, adn you don;t want it cutting out while low and in (if it were a 3d plane) a hover ya know what i mean

Well I have finally managed the maiden of this mode. It has a Castle Creations 10 speed controller, Typhoon 6 3D motor on a 8x4.5 folding prop and a 3 cell 1000 3D 11.1v lipo battery. Flies great it really does, I am very happy with it. Don’t know if I should perhaps try different props as it seems ok. What do you think ?

Only problem I had was the 6 channel Narrow GWS receiver glitched a few times. So don’t know if I need a new rx as that one was brand new. ?

Try to achieve a larger separation in space between ESC and Rx, and route the antenna in a different way. If nothing helps, try sending the Rx in for a check before buying another.
If the plane flies like you expect it to, there is no need to try different propellers. Of course it is good to try and get that last 0.01% in performance, so if you feel like it go ahead (and perhaps report about the improvements!) [8D]: the 8x3.8 or 8x4.3 APC or GWS slowfly props should be a little more efficient than the folding prop you currently use.

Thanks for your reply. I shall try that with moving the RX. The only thought I had about non folding props was the fact that I dont use the undercarriage/landing gear on the formosa as i fly off of grass and it would be too fragile and i would have thought that if i did not have a folding prop it may damage the model, or motor mount ?

It's all a matter of weight. If your model is light, then it should not be a problem. You can give it a try with a GWS (very cheap) if you want to test, and then decide. As I said earlier, if you're happy with your current setup there's no need to change anything. Just have fun!
