33% Lanier Laser 200 - power setup options

[Stuntman]

Well, I acquired a NIB 33% Lanier Laser 200ARF (96") for a great deal the other day and am intending to go E-powered. ;)

Not having done something this big before I am after some opinions, but I would prefer to use an outrunner solution.

I have looked at a couple of options including the budget HXT 80-100 motors (weight is roughly equivalent to a 50-60cc gaser) but they seem to have some issues, and I am starting to warm towards a hyperion Z5045 - but they are lighter and balance could become an issue.

I'd like to get away with a lower cost solution but don't want to buy twice either

Allup weight will be in the 20-21pound region I think, and being an older design is more suited to IMAC style rather than 3D style aerobatics. Can anybody offer some thoughts, advice, etc.


cheers, Shawn

I use the hyperion z504518B in a 30% extra 260, 12s 4350s 24x12 apce prop
its around 3600 to 4000 watts depending on packs and flies the 15LB plane well

I am sure it will work for sport / pattern flying, you may want to do 2 things
1. experiment with a higher pitch prop maybe a 23x15????
2. go with the biggest packs you can get ( 2 6s 6000ma lipo)
or doulble up and go 12s 2p with 4 6s 5000 ma lipos , that will get the cg right and give you very goods duration and power!

Have you seen the Vortex range of motors? They are a lot cheaper than the swanky types.

And if you want some cheap ESCs try:-

Even the largest motor vortex sells, the 63/62/286 at 630 grams is much to small to fly a 33% laser at imac performance

at 286 kv it is limited to an 18" prop on 10s

I'll be watching this thread as I have both a 1/4 scale Lanier laser 200 and a 1/3 scale Lanier Laser, both of which are partially constructed.
My plans were for a G26 in the 1/4 scale and a G62 in the 1/3 scale.

[Stuntman]

If I was going gas, it'd be a 60cc sized gasser. The review over at RCuni..... used a ZDZ80. It was a little too heavy and had way to much power and the reviewer suggested a 60cc sized motor would be an appropriate sized power plant in retrospect.

So maybe the lighter hyperion with the weight of the 2X 6S 5000-6000 (or 4x) would be right on the money.

I think I can get the weight down a bit more. Box suggests 17-22lbs, the Zdz80 powered one in the review was 21.5lbs (or thereabouts) dry. Maybe 18-19lbs is possible with some relocation of the servos (its setup to have 4 servos in the tail 2xelevator, 2x rudder). If I move the rudder up under the canopy and use one larger servo on a pull-pull setup that'd be a good start.

Well I just completed my 33% Ultimate biplane with a phenomenal setup. Plenty of power and very fast which is not common on a biplane of this size. On your monoplane it should rock. The following setup will fly your plane beautifully:

Turnigy SK 170kv motor (from hobbyking.com)
Sentillon 100 amp, 12 lipo speed controller (from hobbyking.com)
Apce 24x12 prop
12 lipos

My bird is weighing about 23 pounds actually and I'm getting enormous power with a 24x12 apce. Pulling about 90 amps. Also, my bird is running on 14s2p a123's which is 5 pounds and 8 ounces just in batteries. Considering a123's have a lower voltage then lipos, this is equivalent to 12 lipos. But I recharge every 15 minutes. :)

Lipos would save you good weight but then you have to worry about c rating, heat and having to switch batteries for every flight which is a pain. I'll have the extra 2 pounds for the added convenience.

So you have an idea, I was getting 25 pounds of thrust on 13 a123's with a 24x12. I haven't measured how much thrust I'm getting now with 14 cells but she pulls much harder. The setup above will run you $170 for motor and speed controller and is guaranteed to fly your plane since it is what I'm using.

[Stuntman]

Thats great info blnk00, and I hadn't considered A123's.

What powersource are you guys using to charge at the field? My club doesn't have power so this is a consideration too.

[BulletMaster]

nice project S.... should be nice when it's finished. But the little car might struggle?

[blnk00]

Well if you go the a123 route, anything larger then 10 cells and you're better off buying a Mastech variable power supply. That will put you back $290. You don't need to balance a123's, you just charge them and go, they balance themselvs. The Mastech power supply is what I use at the field. I charge 28 cells in 15 minutes. But you need 110v source. If your club doesn't have a power source then you would need an inverter to use the power supply from your car battery or a generator.

If you use a 10 cell a123 pack instead, you can purchase a charger from hobbyking.com for about $200 that will charge 10 cells. I have that too for my smaller packs, works great. Just attach the charger to your car battery and charge. Make sure the car is on or you will drain the battery.

But if you use 10 cells on that plane you will need to purchase the Turnigy SK 230kv motor instead of the 170kv. The prop will be a 23x12. This will fly your plane decently since I had it originally on my biplane before the upgrade. Don't expect massive power though with 10 cells. But she will fly and fly nice.

[BulletMaster]

cheap generator S? Ebay special?

[Stuntman]

I have the chargers to do the job (both A123 or LiPo), its just the power source that I am wondering about as our field doesn't have power onsite.

I have a deep cycle battery and its ok for upto 5S, but its just about near the end of its life and is struggling to hold voltage. One of the guys is using two together for a 24V source, but maybe like bullet has suggested a generator - but then why not just go gas. One of the points of of E power (for me) is not to have to cart fuel around. But I guess a generator eliminates the after flying cleanup.

Ah decisions, decisions.

[Peter M]

Ah decisions, decisions.

LOL! Shawn, I reckon its more like "Ah money, money!" with these big conversions! :D

Geoff Dryer puts forward a compelling case for using Turnigy/HXT 80-100 motors after a fairly inexpensive bearing change (I'm sure you have studied his very useful Hanger 9 Sukhoi thread) but agree that sometimes paying a bit more for consistent quality has its attractions.... :rolleyes:

Another option is to wait another 8 weeks until the new 65mm stator diameter Hyperion/Scorpion outrunners are released. If the recently released smaller Zs's are an indicator, the 65's should be quite impressive and very efficient. But then again, at over twice the price of a 80-100 Turnigy, it should be!

I look forward to seeing what you end up deciding on!

Cheers

S... I have a 1KV ebay 4Stroke generator that runs for about 6 hours on a tank of fuel. Perfect for your app (plus you wouldn't need to re-fuel at the field). I also have one of the HC 16A powersupplies that in combination with 2 x TP 1010C chargers I can charge 2 x 6S Lipo at 5A with no problems at all... Thinks you can get the 1KV units for about $500-$600... Very handy..

[Stuntman]

Well the $$ for that generator is not far off a good deep cycle 12volt battery and certainly a bit less than two batts to make a 24v solution, so maybe its a good longer term option. Hmmm this hobby just keeps ya gettin in deeper and deeper :D

Peter, I am going to revisit the HXT's, but yeah will wait to see what the new 65mm hyperions look like. No rush with this one just yet - got to get the talyorcraft finished (with sound:D) - but in the project sope out stage (which is all good as the Aus$ is heading back up).

cheers, Shawn

good ol' HC agin :)

[blnk00]

I have a large boat deep cycle battery that I keep in the car. They run $100. I use that battery to recharge my 10 cell a123 packs at the other field where there is no power outlet. I go for about a month without having to recharge the deep cycle. Very convenient.

And I fly Sat and Sun.
