Re: Trimming

Thanks for all the help guys! I'll definitely try and keep that in mind next time I can use a gym. Not sure what the height is to the lamps right now, but I'll check. And yeah, I think it is a prop/rubber match issue. Thanks again!

Trimming

Wasn't 100% sure where to post, but I have hit a wall. I am using a ffm 2015 plane, and can't seem to exceed 3 minutes in the air. I've been having the best luck with thin props and narrow rubber, but it almost always lands with nearly half of the winds on it. Here is a video. It is using a trimmed ...

Re: Design

Have you tried using a helium filled balloon to retrieve it? That would have been smarter... we used a huge pole. Unfortunately, the prop was REALLY stuck in there, so in the process of getting it down the tailboom broke off of the fuselage and somehow managed to get wedged in the light. We recover...

Re: Design

Worst possible feeling... last flight after three hours of testing too... Time to whip out the backup planes I guess; regionals are in 3 days.

Re: What are your guys times right now?

Rubber is your fuel and your engine. Thickness is power/climb. Mass is fuel. NEVER fly with less than 2.0 gm of rubber, its like flying with a half full tank of fuel. Jeff Anderson Livonia, MI I remember hearing this, i didn't think too much about it. But I guess I'll have to give it a try, so than...

Re: Bottle Rocket B

I am looking to buy a new rocket launcher. Has anyone purchased the Bigfoot Water Launchers? Any good? Any other brands any would recommend? I have a friend who bought the bigfoot launcher and thought it was great. Back in 2012, we used this: http://www.pitsco.com/Aquaport_II_Water_Rocket_Launcher ...

Re: Design

This may be a dumb question, but if I have a dihedral, will the ES measure my wingspan by measuring across from one tip to the other? (like measuring the distance across the top of a "v") or will they measure the total length of each panel (as in measuring the total length of both arms of a "v")? I...

Re: Air Trajectory B/C

Has anyone had much luck with the racquetballs and practice golf balls? I've almost entirely seen people using ping pong balls, but they have a really poor flight pattern and tend to curve in the air. Practice golf balls don't fit well in any of the pvc tubes I've tested them with, anyone have luck...

Re: Design

I've noticed that Armor all has been frequently recommended for lubricating motors. I looked for it on amazon and found this http://www.amazon.com/Armor-All-10228-Original-Protectant/dp/B0007898UI/ref=sr_1_1?ie=UTF8&qid=1422241231&sr=8-1&keywords=armor+all Is this the armor all that you guys are ta...

Re: Bottle Rocket B

Yep. Sorta. I can't speak for OpenRocket but RockSim even calculates the weight of the rocket fairly accurately given the materials you select for the various sections of the rocket. Once you've done that you have to select an engine. Even though "water at 60PSI" isn't an option, it doesn't really ...
