RE: Hangar-9 Pulse XT PNP

I'd agree. Good quality, good engine, excellent second plane...... and third....and fourth.

It's a good performer when you get into it. It's one of those planes you'll use for a long time no...

RE: melody 1500 with twin edfs

I was looking for he weight of this model on the internet. I haven't found it yet. What I did find was it looks like parts are not available for this plane.

Check it for yourself, but with the...

RE: Electric motor generalities?

Just a couple ideas. A three cell pack will help quite a bit, usually ESC's will work with a 3c pack.

I'm sure you have, but did you move your CG after all the mods? A nose heavy plane can fly...

RE: Vertical Stall

Whatever the terminology it boils down to your engine is not producing enough thrust to pull the plane vertical. The easiest solution is to check your tuning.

RE: help??? Second Plane from walmart??

The cheapest complete plane I can think of is the Hobby Zone stuff. The Super Cub is about $150 or less used. The Aerobird is around $100.

Both are a little better than toys. The Super Cub is...

RE: Stupid question for clever people

I'm too lazy to find the link, but Graupner said (if I remember correctly) to convert to a 3-blade from a two blade subtract 1" dia or 1" pitch. For a three blade to a four blade subtract another...

What kind of performance are you looking for? Unlimited vertical? Or just get it in the air?

Yea, and if you're getting confused by all the motor specs, wait till you start comparing motors of different manufactures......

RE: Bought my first biplane!

Any way it'll fit. Don't drill any holes in the mount till you think it through and plan.......... Hopefully not inverted though. <groan> [:@]

RE: Maidened the downer... good and bad/help with fuel soak plz

Something that might make you feel a bit better: Yes the fuel ruins the wood and yes you have to clean it up, but soaked wood doesn't mean your plane is ruined.

Do the best you can to clean it...

RE: Amp Draw?

If you hammer the throttle and your motor pulls a maximum of 40A with a properly sized prop:

You want the ESC to be able to deliver AT LEAST 40A without damage to the ESC. SO, you pick a 45A ESC...

RE: Hey crew, new to gliders - need some help.

I'd agree with not using an ESC being heavier. You'd either have to run a switch and seperate battery (to eliminate the possibility of running your radio battery too low) or run a BEC that is in a SC...

RE: Bought my first biplane!

I'm jealous. These are beautiful planes on the ground and in the air.

There are two of these at the field I fly sometimes. Awesome man! I'm pretty sure it'll do every stunt in the book.

RE: Electronics suggestions

What will be the weight of the craft? Or how large physically do you expect it to be?

RE: What voltages should I stop flying at?

FYI, I fly till 4.6V and 9.4V

0.9V per cell I believe is in danger of damaging the cell (which I don't realy agree with, but that's what they say)
1.1V per cell is a operational minimum
So,...

RE: Spinner for APC 12.25x3.75?

I don't think any spinner fits that prop off the shelf. I used a prop nut. I could have (and do) cut the spinners, but I didn't bother on that plane.

You could build a R/C - Moller M150 Skycar model! I'll bet two OS .55AX engines would haul a 1/4 scale model of the M150 around pretty good!
