thank you.
My power package cost me $62 (ESC/motor/prop)

Unorthodox setup, but the video is two posts above, you make the call.

The only disadvantage to a small prop with 1000 watts is if you stall or you need to get out of trouble, you need WOT. 1/3 throttle will get you moving, but if you need to bust out or go straight vertical, you need to floor it.

This is my first experience with 7 and 8 inch props on a glider of this size, but it works when you want a cheap setup. You just need the watts.

JohnnyRocco123,
great vid up above like you said, but I think over 900 watts for a
newb like myself is too much.

Im coming from a Radian which has 180 watts.

is there a powerPackage thats more like 300-400 watts?

do you think the 300watts is too low? may stall a lot?
I think 400 watts is better.

where do you get your electronic powerPackage?
(esc/brushless/prop etc....) great price what you had....
I'm interested !

It's all from hobbycity. The model numbers are in the video.

I tried this plane out on 500 watts the first time around. It didn't have enough authority in 15mph winds. It was a disaster. It wasn't until I moved up to 800-1000 watts that I felt like the power was fitting.

Moving from a Radian to a Siren is a big jump if you haven't flown with ailerons before?

If you have experience with ailerons I would say this is perfect. It is my first "hotliner" although I have hopped up gliders in the past.

The thing that I had to get used to is the giant wing. You have to be careful turning at low speeds. It sinks like lead if you stall out. That's why a bigger prop would probably be a good idea for a newbie. IMHO.

I fly little pylon racers and figured it would be like flying a giant one.....nope. Not at all.

One more thing. If you don't have decent power, you will be all over the throttle, non-stop. Power is good for these planes. All it takes is 3 to 4 second bursts and you are across the sky or way vertical. Then you can float around and try and catch a thermal.

RC
refer to page 1 of this review on a primary setup for your first time Warmliner.These are good starting points on motor,esc,props etc.
From there, glance through the rest of the review,talk to allot of people,and ask tons of questions..The more info you get,the better..Most of the mistakes have been made already at other pilots expense,you just need the patience to sift through all the info and determine if it suits you or not..

Flight...

firewall support

During a flight the other day I noticed a different kind of vibration noise. After inspecting, I didn't find anything solid. But while I had it down I decided I should beef up the firewall, so I don;t have to worry about it.

What's the best way to do this?

If I put a layer of fiberglass cloth over the firewall and load it with epoxy, which cloth thickness? Do I overlap it?

Do I just drench it with epoxy and then sand it down and re-drill my holes?

Is there an alternative or better method?

Thanks guys

How thick is the stock firewall? With the power you are running there may not be enough mass in the firewall/fuselage joint to handle even a small imbalance in the prop/spinner. Also, make sure all of the motor mounting screws are tight. You may want to beef it up from the inside to get more glue joint area between the firewall and the fuselage.

Ok, you say replace it. Sounds like a good idea, but how do I do it without destroying the front of the fuse? I'm a foamie/balsa guy, I have no experience making mods or fixes on something like this. In the last fuse, I just about tore a hole through the bottom trying to get the battery tray out.

Go to radio shack or michaels..from Radio shack,buy a piece of printed circuit board,and make one.Michaels has some real fine plywood,like 1/8 or 3/16 thick..they come in like 1'x1' foot squares..
For removing it,just use your handy Dremel tool and cut it out..once you get it down close to the fiberglass,use the small drum sanding disc and finish it off...

I removed mine and rotated it for the new motor.

See it here.

I have to tell you that if yours is like mine there is little or no epoxy on the back or sides of the firewall. Once you remove and reinstall it with the correct amount of epoxy it will be much stronger.

Circuit board over ply? I'm thinking mine cracked from tightening screws with lock washers. I didn't over-tighten either.

When I glue the circuit board back in should i use straight epoxy or should I put some fiberglass filler in it?

I'm off to try and pry the other one out.

nibble out the old one,then use the drum sander to take out the rest..
I think straight epoxy is good..I tack mine in place with Ca,then lay in a nice fillet around the perimeter.
Layout the holes for the motor prior to installing the firewall..
While you are at it ,make extra firewalls for other applications..leave them big,you can turn them down in a drill motor for a perfect fit...

McMaster Car has G10 fiberglas plates in 1/16, 1/8 etc thickness. A 12x12 sheet will give you enough material to make a bunch of motor mounts. Stick some paper on it and draw the diameter that you want, mark the motor holes on the correct diameter and sand and drill. Takes about half an hour from start to finish.
