RE: 1/2A trainer anyone?
Both. Some fuel tanks give you a diagram of how to set it up. The most critical element when setting up your tank is to cut the line to the clunker the right length. Try to cut it so it doesn't touch the back wall of the tank. Leave it short about 1/16 to 1/8 inch.
Most plans will give you the proper height of your fuel tank. The basic rule of thumb is to mount the tank so that when the plane is level, the centerline of the fuel tank is at the same height or slightly lower (no more than 1/2") than the high speed needle valve. You should also keep the fuel tank as close to the back of the engine as possible so the fuel lines can be kept short.
It is also a good idea to wrap your tank in foam prior to installing it into the plane to prevent fuel foaming.

RE: 1/2A trainer anyone?
mnrcaerobat, when you say you built up the center section out of spare balsa, do you mean like a solid section, and then add the dihedral after this part...
this is the part I'm confused about?? the dihedral in the center section of the wing??
any help much appreciated..

RE: 1/2A trainer anyone?
A great favor... somebody have kadet senior's plans(full size)??? I'm beging with a work about aircraft aerodynamics and I think that mathematic model of the Kadet Senior would be don't complex because it has a very good lateral stability.
Thanks...

RE: 1/2A trainer anyone?
i have seen that plan and would make an interesting 1/2A, would just need reducing in size and lightened.
my Trainer is almost done, just on the back burner as haven't got much time at the moment, will finish soon

RE: 1/2A trainer anyone?
Hi there, I'm from Singapore and just getting into R/C airplanes - think 1/2A makes plenty of sense here since fields are small and winds are light. Electric is one option, but I like glow.
Keen to build my own LST; having difficulty with the power plant - I can get an OS .10 LA for less than an enya 0.09 over here. A Norvel .061 AME would cost almost double the OS! A cox medallion (throttled) would cost about the same as the OS. Parts for anything but the OS are iffy. Would the OS .10 LA be too much engine for the LST? Am prepared to go with the enya .09 as an alternative, but would this also be too much engine?
Any help/suggestions would be very much appreciated.
Thanks!

RE: 1/2A trainer anyone?
I think the .10 would take away from the best characteristics of the LST designed for a smaller engine, but that is not to say you could not change the scale of the plan to suit your most available power plant.

RE: 1/2A trainer anyone?
If you can't find something at a reasonable price, use the .10. I designed it to use up to a .074, which has as much or more power than an OS .10. You can always throttle back if you need to. Or, like dieFluggeister said, scale it up a little.

RE: 1/2A trainer anyone?
Hi, thanks for the reply.
Yes; I was surprised to see that the Norvel .074 actually puts out more HP at a higher RPM than the OS .10LA while weighing a good deal less. Anyhow, figure the extra weight of the .10 might be useful since I remember reading an earlier post that indicated the LST needed considerable weight on the nose to be added for it to maintain its designed CG.
I already have a .15 LA and am comfortable with it - starts real easily by hand too. Figured the .10 would be similar and a safer bet than getting something unknown.
Sadly, prices and support for anything except OS are a little silly over here.
btw has anyone used an enya .09 IV-TV? Think I can get one on clearance and it does weigh a little less than the OS .10LA. Dunno what its like in use though.

The OS .10la might not be a powerhouse, but it's dead reliable! Sounds like a good powerplant to me. Like Bipe Flier (the airframe designer!) says, don't forget you got a throttle!

RE: 1/2A trainer anyone?
I'm not familiar with the enya 09, but I do have its bigger brother 15IV TV R/C and its really good a freind has the 19 and its also dead reliable. From what I can gather Enya motors are of very high quallity and very good sports motors , buy this I mean they generally have smaller venturies for there size , as a result outright power is slightly down on the competion BUT they throttle well and with the normal sports sized props performance is about the same as most.

RE: 1/2A trainer anyone?
Thanks for feedback. Read somewhere that the enya .09 is very similar to the .15 and that they're both very good engines. Have nothing against enya - just worried about local availibility of parts. Over here, the .09 will cost just a little more than the OS.10LA. Tough choice....

RE: 1/2A trainer anyone?
Hi guy`s.. UNCLE D. wants to surprise the KIDs with this plane... Is the last posted materials list, sufficiant??
I want to use an 0.049 cox,the other engine I have given the boys.
" " " " my futaba 7chp and the the receiver that came with it,,127 DF
" " " " a standard size x3 servos AIERONS, rudder, and elevator,maybe a throttle too(unsure)
WILL this fly??maybe scaled up ,or down??
Could someone put the current revised plans, and any other, relevant up dates in here,PLEASE...I can`t get them to upload from the other links..I`m leaving for the hobby shop shortly ,and would like to have suggestions on what else should be purchased...I want to build this really quickly....I`m not going to envolve the KIDS on this one ,except to fly it..does this require an iron-on covering or is it a complete sheet-up.I really don`t have time to investigate right now and the store is a 2 hr. round trip. AXLE wheel.landing gear.whatever.Thank you I`ll be watching DAVE B.

RE: 1/2A trainer anyone?
Hey Uncle D.
Raidio and RX are good. I would highly recommend an engine with throttle (and servo) if it is going to be used as a trainer. A Norvel 0.61 would fit the bill. The 049 you have will probably fly it but you will want a light build and equipment. Servos of micro size (ex: hitec hs-81) are prefereable but standard size will probably work but you will be handicapped by weight. It is a coverable model and will take at least one roll of covering depending on color scheme.
Dont forget control horns, clevices, pushrod wire, aileron linkages, wire for gear, wheels, wheel collars, hinges, spinner, fuel tank, fuel line, battery, switch, velcro tape, rubber bands or nylon wing bolts, props... did I forget anything? Oh and pick up some extra epoxy and CA for me will ya?

I`ve got.clevices,props, pushrod wire,battery, switch, velcro tape,AND hinges,.Going to use a film tank.WHAT SIZE wire FOR gear,(i`ll BUILD SOMETHING LIKE THE S.E.5a) wheels,and wheel collars? will use,nylon wing bolts

RE: 1/2A trainer anyone?
Got it ..THank you... I`ll be leaving soon, and BACK in about 4,1/2 hrs, maybe this would be a good time to document a step by step for this plane what do you guy`s think. I`ll probably ask for advice from Y`all ,along the way,..BE real good for the begginers maybe..??? only thing is I want to blast through the job. D.B.

Yes, please post construction photos.
If you are unable to download the plan from 1/2A all the way, use [link=http://www.donatelli.net/images/LST-½A-Trainer.gif]this link[/link].
There's no point in trying to post the plan on RCU because it will be reduced to 800X600, which is unusable.
