Is there a way?
I'm getting 20 minutes of flight out of my superstar right now. I know that is plenty of flight time but i want more. I know the jet industry <both r/c and real> use a sort of Kevlar wing tanks. Could i put theses in my trainer? I'm takling little 3 oz. tanks in the wingtips. I know it'll weight her down more but right now its only a little under 5 lbs. is this possible? Any info appretiated.

RE: Is there a way?
Don't worry about it. Once you learn to land, you'll find that landing and taking off is one of the best parts of flying. Rigging wing tanks would require some serious plumbing (that can result in screwing up your fuel mixture ratio anyway). Besides, if you fly with others, you'll find they tend to get ticked off if you're hogging the sky (or frequency).

Ya i know what your saying about hogging the sky but know one else runs my freq. there. I just wanted to know b/c i heard some club members talking bout getting bug gliders to tow up but they don't have a tow plane. So i was gonna put in somthing like a .58 four stroke and tow for them.I saw on tower just know 1.5 oz. bullet tanks. What about mounting those on the wingtips with servo tape or a bracket system?

RE: Is there a way?
As Mike said, you'll have trouble keeping the mixture setting right. If you really want more time, find a way to install a lerger tank in place of the original. (A four stroke uses less fuel, so you'll get longer flights. ;))
One other thing, a .58 four stroke on your trainer isn't likely to have the power necessary to pull a glider up, a .91 maybe.... Dennis- |
RE: Is there a way?
Towing isn't real easy with a 40-size model anyway. Many years ago my friends and I played around with it with very little success. If you want to tow a glider up, get a larger model.
|
RE: Is there a way?
yes a .91 and a 20 oz fuel tank.......hehehehehhehehehehe........that should last an hour at half throttle[&:]
|
RE: Is there a way?
How long will it take you to tow up a glider anyhow? Should only take a minute or so right? Or am I mistaken?
|
RE: Is there a way?
Correct, a few minutes is all you need. We've done it lots of times. And while extra power is a must, a 70 4-stroke should be plenty, and it will give you longer run time than a 46 2-stroke

RE: Is there a way?
I've seen a glider towed up once. The most important thing I saw was the speed. Too fast and the glider does snap rolls. It was cool. So, to sum up, make sure that your plane has power, not speed.(large, low pitch prop) As long as your plane can stay up for 10 minutes that should be plenty of time for towing gliders.
Back to the fuel issue. What I would do if you really think it is necessary, put another tank in the fuse, put the engine exhaust to the exhaust attachment on the second tank. Then take the second tanks clunk and move that to the first tanks exhaust deal. Then take the first clunk and put that to the engine. I don't think I would bother though, unless you want endurance. |

One other thing to remember if your fuel capacity is greater then your receiver batteries run time you are going to run into problems.
:D You may find out how far a plane can fly on its own!!:D |
RE: Is there a way?
How about a scale model of a KC130 - you could do air-to-air refuling.... [X(]:D
|
RE: Is there a way?
You could always strap a heli header tank on top of the main tank and stick it out of the fuse. Personally, I would just land and refill it quick. Just takes a second and gives you a chance to grab a drink of water or chat with the others while you are filling it.

RE: Is there a way?
Went to my local BJ's saw 6 panasonic 3200 mAh NiMH 1.2v cells for $10.99 WHAT A DEAL!!
Make a reciever pack! Is this idea problematic? The packaging did not say the cells are matched. It just says, USE ITIN YOUR GAME BOY! IN YOUR DIGITAL CAMERA!! I did not buy it yet. Should I? I Mean it said 3200 mAh MAX. |
RE: Is there a way?
Not a bad price.
But those batteries won't have solder tabs and you will need a charger. |
RE: Is there a way?
Yub, if you are looking for longer flying time, get an addtional battery and change it out when needed. Otherwise a quick charger or Lithium battery and charger. If you build one from cells you know nothing about, will it stay together in the air with the vibration? I wouldn't chance that with any of my planes. Would you?

RE: Is there a way?
I've got a battery pack in my TX and one in my heli... both are made from Ray-O-Vac 1800 mAh AA NiMh cells. :D They are a bit havier than the NiCd 700's... take the exact same space though.
Its fairly safe to charge them on the radio's original wall-wart, C/36 rate is almost a maintenance trickle, but I can't safely leave them on beyond full charge. (for the 3200's it would be C/64.... or 3 days to charge it. you could leave it 72 hours safely starting from a partial charge.) The NiMh peak detecting chargers are getting inexpensive. (even the Li-Ion chatrgers are comming down) |
