ok i've been outside tonite to start the N9 for the first time and just run the engine .Problem i have a flight box with a 12volt jell cell battery that is fully charged , my starter is a Ripmax turbex 2 it will not spin the engine over in fact its .......crap ! ! so have given in tonite and will have to buy a new starter the question is WHAT SHALL I BUY ? is the battery anygood ? do they do a starter with its own battery built in ?, first time i've tried to start a 90 size heli not had any problems with the 50 or 60 , guess its just the size of the engine .

Don't need a new starter run the starter you have on upto 16cells Sub c of around 3300mah or try it on a fully charged car battery.

Gel cells are no good for 90 motors.

I run a magnum geared starter from weston uk £30 and 16 cells 2 years no problems.

Thanks droid , by c cells do you mean the 1.5 volt cells like you use in a model car ? so basicly you are running 24 volt through it .

I have 2 12v gel cells in series spinning a regular starter. The setup has been working for almost 4 years now on my ys91 with very few problems. The batteries recently started having problems holding their charge so I replaced them.

No, 12 to 14 volts not 24. Try another starter with your battery.

Sullivan or Hobbico work well. I use the Hobbico Torque Master 180 with 2400 Sanyo C batteries.

Go to Rick's to see how they recommend using 2 6-cell per pack (2400mah or 3000mha) in a remote starter setup. I'd suggest Power Pole or Deans connectors versus the Tamya type white connections pictured. Power Pole can handle 30 amps.

If you run too high a voltage on your starter you can damage your motor if you try to start it with too much fuel in the cylinder. Vapor lock is the term.

Thanks Chuckie ,i have a couple of 6 cell 2000mha pack kicking about if i wire these together with my starter do you think they will be good enough ?

Sure give it a try. With 2000mha packs you'll just have to recharge then more often.

Hi

I use a 7amp 12v gell cell battery with no problem at all, starting all 90 engines, this is with a Dynatron starter and I solder the wires directly to the battery so very little loss.
This set has worked well for me for years although I change the gell cell every couple of years.

Cheers

Thanks Bob , i could try putting the starter straight on to the battery as it goes into a power panel at the moment , when i check the voltage it reads 14 volts on the battery but through the power panel it only reads 12 and if i put load on the starter it drops to 9 volt ,might be worth a go ???

Hi

The Ripmax start is not really up to 90 engines but certainly going though a power panel makes life much harder for it as normally PP wires are fairly thin so won't take much current.
Give it a go anyway.

Cheers

Hi Simon

As I said I use a 12v Gell cell same as you but a Sullivan Dynatron starter and a Robbe hex start shaft, both are not cheap but very
good so you will only have to buy them once.

Cheers

I use two 12v Gell cells wired together to give 24v for starting my 90 models with a Sullivan Dynatron and it never fails. Just make sure to turn the engine over by hand first to check it's not flooded before applying all that torque to it! A single 12v Gell cell just doesn't always seem to have enough punch...

A Dynatron with 16 x sub C nicad cells is all I use, starts all my 90's, also with the K & S Battery holder you can get everything into a compact unit. See the pic below... There are a couple more shots of it in my gallery too

Dont forget that you have a brand new motor too. You can loosen the glow plug a little for the first couple starts. Once it's started tighten it up and your golden. The dynatron is an awesome starter BTW.

if you want something that will last get a dynatron and robbe wand. i had a few other starters before i bought this setup but nothing beats it now, i have a pair of nicads on it for power.

there is a certain few cheap skate idiots at my club (one in particular) who just buy the cheapest starter they find and it never works, they always end up borrowing mine. spend the money and buy the dynatron and robbe wand.

cheers

I do a sullivan dynatron on a 7 ah 12 volt gel cell and it barely starts my 90. If I run the engine to tdc with my hand on the start wand it can often turn it over. I have a new gel cell and a plug type setup on my field box capable of handling 40 to 50 amps. One thing I'd definately not do even though the sullivan can take it is to use 24 volts. A....if you hydrolock you will stuff your conrod B...It can fling the starter and wand right out of your hand (been there and done that) C...if it doesn't start straight away then the revs on the starter are enough to cause the heli's clutch to start grabbing. (been there and done that)

I am gearing down my sullivan with two timing pulleys and a kevlar timing belt. 1.75:1 Don't need speed to start these things....only torque.

A lot of guys use the two nicad setup (14.4 volts)This does it nicely with the dynatron. It's just if you get the cradle and stick the batteries on the dynatron it's a pretty heavy setup. I find it a pain to have to charge the nicads so I'm going with the geared down system and that way I can trickle charge the gel cell overnight every month or so.

The dynatron is a good starter. 14.4 volts is necessary in my eyes as 12 volts on the dynatron is just a wee bit lacking in torque.

Once my Cspec was broken in I didn't have a problem using a gell cell as long as I didn't run it through the power panel. I smoke checked the Power panel the first time I did it. As for hydro locking it.... I got that figured out too. clip off the fuel line to kill the motor on your last flight and don't open it to allow fuel until right after the starter starts spinning. Works EVERY time.
