No that i can think of for the pane that is you will also need some "field" equipment such as
chicken stick
glow ignitor
fuel pump
those 3 tols are the ones that are used the most and you should be able to make dew with those dont forget you can always ask t borrow stuff at the field

Wild Foamy

ive got a glow igniter from my HPI savage and a 500cc fuel bottle, a fuel filter, a chicken stick could easily be made so that isnt much of a problem...

i was thinking of investing in a "6V hump pack" as i dont want to use alkalines which are expensive but i still want maximum range and power to the servos

You need 5 meters of servo wire? That's what the radio is for. Sure you sure the servos don't come pre wired? No wonder I've never heard of "Jamara" equipment. Hitecs over here have wires, but you have to make sure the receiver accepts that plug. And batteries for Tx & Rx if not so equipped.

You'd need also 30 minute epoxy, white glue or thin and medium CA, #64 rubber bands, one more wheel (the Seniorita takes two 2-3/4" and one 2-1/4"), 3 of 1/8" wheel collars to hold them on. Two 2M rolls of covering, more if you want to pretty it up (or trim sheets). A 9X5 prop.

Here's a link to a partial list of what you need for a Seniorita:

Wild Foamy: with 6V the servos would give more output but for less time. Increasing the voltage has it's costs. The old analogy is putting more holes in a bucket. The water comes out faster but for not as long.

Wild Foamy

if you put 4 1.2v rechargable cells in a 4 pack holder, you get 4.8v, right?

BUT, a "hump" pack incorporates a 5'th cell to make it an even 6v, and seeing as it is adding 800mah more to the circuit wouldnt it last longer? (assuming the cell is 800mah...)

and the servos are pre-wired, the cable is cheaper than extension leads so if i need to extend the servos i can

but come to think of it... with the glue, wheels, collets, covering e.t.c i may be looking at £200 for a trainer... is this a good/average/expensive for a 60" odd wingspan?

and as for the collets i dont think i will bother... couldnt i just drill a small hole through the axle and use bodyclips from my savage and washers to keep the wheels on?

Wild Foamy,

All you need is a 4.8v 600mAh pack. That's what I normally fly and the charge easily lasts for (7) 20 minute flights. I've flow this size pack for a bit over 2.5 hours straight on a glider that probably used more power than the newer radio you going to use. Now if you were to fly a precision aerobatic (read pattern) plane with digital servo's, then I would say yes to the 6v, but for your case, just keep it as simple as possible and fly a 4.8v 600mAh pack.

My Feedback: (9)

Ok, first off I sincerely hope that you aren't seriously thinking about putting cells in a "pack holder" for your receiver batteries. This is a sure-fire recipe for losing your plane. I imagine in cars you can get away with doing this, but you can't in an airplane. The vibrations from your engine will cause the batteries to lose contact and you will lose receiver power. You need to purchase a premade rechargable battery pack.

As for lasting longer, the answer is no. The servos will move faster but you won't get longer run times with it. Trust me here, a standard 4.8 volt 700 Mah pack is enough for at least 3 flight of 10-15 minutes. That's a lot of flying time for somebody that is training.

Unless you are very good at soldering your don't want to mess around with trying to make your own servo extensions. One bad connection cost you a plane here.

cheers lads

ive updated my list, which is growing in price a lot... still not sure what prop(s) and spinner to get for engine run-in and normal flying (im going to run a thunder tiger GP-25) so anyone got any ideas? and some advice on covering would be good...

and also, should i use a failsafe to stop it flying off into someones house/car if i loose control of it?

Charlie P.

9X5 for the prop.

I don't have a failsafe on any of my planes. If it's out of range even a failsafe can't distinguish what it's going to hit. A PCM can be set up to cut throttle and give a bit of rudder (and a chance it may come back into range or pancake in instead of meteor). The new sky/ground detectors may get a hold of the plane if they're on board, but I don't know how they actually function in use. I've only evey known one fellow who was monkeying around with one and it was working.

Agreed that it isn't intuitively fair that adding voltage will not lengten the flight time, but instead shortens it. Curse Ohm and his laws. As mentioned, add more mah capacity, not voltage. Even better, get additional battery packs. You have to refuel every so often, anyway. Swap out batteries and keep flying all day.

Missileman

When adding more batteries in series voltage increases and current remains the same. Adding the 5th battery does not give you another 800 mah. Assuming the batteries are all 800 mah batteries the entire pack is still only 800 mah.

Can I guess this is your first time flying
trust us you don't need 6 volts on a trainer
things will happen plenty fast at 4.8
keep your first plane very simple you'll enjoy it more
focus on flying you can get a hotrod later

alan0899

G'day Mate,
You are not adding 800Mah, you are adding 1.2Volts, they are wired in series, which means more voltage & hence more current, being forced through the load, servos, electric motors & so on, hence more speed, so the battery will only last about the same time, the only way to get more capacity from nicads is to buy larger capacity cells, that's why there are 600, 800,1100,1500,1700,2000 Mah, etc. cells, but they are all 1.2 volts per cell.
You don't need more than 4.8volt packs, 700, 800 or 1100Mah, until you start using either high torque, or digital servos.

Wild Foamy

ok, thanks for the input

im not really confident with building a kit aeroplane (which is what the SIG is... i think) as i havent got any of the tools, materials or experiance... im thinknig about finding a ARTF plane or something similar instead, any suggestions?

bruce88123

Sig also has ARF's.

bruce88123

More importantly, what is available on your side of the pond? Buying/shipping a SIG plane may get expensive.

bruce88123

I don't remember if you found a club yet or not. If not, look here: http://www.bmfa.org/clubs/clist.php
The club people can give you some guidance too.

Wild Foamy

i have found a club who are willing to teach me, but in regards to shipping a SIG yes it is very expensive

SIG Seniorita kit will cost $35.34 to surface mail ship, $45.89 for air, $74.45 UPS worldwide express

so thats about £20 to ship, and $64.00 for the plane (roughly £50) so £70 for just the plane, and then i need covering, fuel tank, wheels e.t.c

Wild Foamy

and also, ive found sig Senior ARTF's, but no ARTF Senioritas, only Kits

Wild Foamy

"Wing Span: 63 in"

thats the same as the seniorita, but its a 40 sized trainer so would it haave higher wing load?

JPGale

I have the alpha, and I also have the OS 46 LA in it and it is a great plane easy to fly and everything, I would recommend that to you, just get some 30 min epoxy and glue the wing halves together. I would also buy the futaba radio on that page, with very little else you will get into the air.

I had looked for an alpha to recommend to uk but I could not find one back home, well spotted.

Wild Foamy

And the list gets shortened:

Hangar 9 Alpha 40 trainer
Jamara 4 Channel Radio set + RX
Thunder Tiger GP - 42
6oz Radio Active Fuel Tank
Fuel Tube x 1 metre
Hitec HS 311 Standard Servo
Super Glue 50g Bottle Medium compound
Graupner Propeller 9x5

Total: £166.69


Foamy is pleased

And i thoguht that Futuba Skysports radios were discontinued?... i havent seen one for years... but with the futuba system its £212 and thats overbudget for me, and thats not including the P+P or fuel...

JPGale

You may not need the fuel tank etc,

I would if you are going to order from 2 places order the alpha first, and then order the rest once you see what you need. Here is what hangar 9 say you need to complete the aircraft

http://www.hangar-9.com/Products/Rel...ry=Recommended

Also get a bigger prop, that will make a 45 engine very quick, I would get a 10x6, in fact if you pm me your address I will send you a couple of 10x6 zingers I have that I don't use. I have to send some stuff to the UK soon anyway.

Wild Foamy

seriously? cheers bud, im trying all i can to get as close to the £200 maximum mark. PM sent

and is that all i need? ive already got a plug wrench, plug heater, some OS #8 plugs (will it work?) a 500cc Fuel bottle and i think the fuel tubing is included... but its still £205.70... never mind, its not that far over budget
