RE: Telemaster 40
ORIGINAL: DUCO ORIGINAL: edmoor ORIGINAL: DUCO Out freaking standing dude, and your own private field too boot. Some guys just have it all! The flight was impressive and the video was even better. Looked @ a camera outfit that includes a HUD that allows you to veiw what is going on while the plane is in the air, almost like a UAV , man that would be neat. Looking forward to the Telemaster flight. Just paid for a Senior tonight from a member here on the Forum who is just up the road from me. But alas, the 40 will come 1st. Have no plans this weekend, yard work was done yesterday and no honey do's, so should get a good deal of building done. Thanks for all your effort to post this. Rick |
RE: Telemaster 40
ORIGINAL: DUCO Interesting that you should bring that very detail up, I do plan to do just as you have suggested, this is the only thing I have seen that I thought could use a bit of strengthening. I will use a trick I learned long ago to keep from popping a rudder off, the rudder sets into the slot you build into the stab, then this whole affair is attached to the back end of the fus. I will add bamboo dowel pins into the rudder that will be attached to a block under the stab/fus. This should add additional strength and stability to the tail. I also thought about adding wire bracing, seen this on another Tele, but have not made up my mind. I also was wondering since I was up-gunning w/a bigger engine, which was here today, but mailman took back to PO f/me to sign, I was @ work of course! Adding wing braces? I understand if you give too much throttle, you induce wing flutter????? Any help would be great appreciated. When I was 15/16 years old, I lived in Williston, ND. My brother-in-law would bring me to the local fly field so I could watch him fly. Their was a gentleman that had a Telemaster 40 set up with a .60 size 2 stroke. The airplane was rigged to release gliders into the air at altitude. I have always wanted to do that. Now, if I can find someone interrested enough to fly gliders at my new club, I will be doing this most definitely! My Telemaster 40 had a Magnum .61 on it and built completely stock. I never had an issue until my friend flew it into a few power lines... The wing fluttered gracefully forever before it hit the ground. The fuse... that was a different story, however. Brian |
RE: Telemaster 40
yes.....im lost too why most folks think the tail area is weak.....fly the plane like it was meant to be flown and you wont have any problems with it.

RE: Telemaster 40
There isn't much "meat" at the tail to mount the stab to. If mishandled, this would make it easy to break off. When a person goes to put it back together, it could change the angle of attack if not careful.
It's easy to do when not paying close enough attention. Brian |

RE: Telemaster 40
your fillet method is not any different than what i used....it does the same function in my opinion. just dont use ca glue in this area use epoxy....30 minute stuff. i added 45 degree gussets in all my corners on the 40 build. but this is a 40 not a giant tm.

RE: Telemaster 40
i used micro balloons on my joints in the corners with epoxy. the first glue up.....i didnt use ballons. i grabbed the tail section and gave it the torture test.....the stab broke free. so i added some 45 degree gussets on the inside....mixed up a batch of 30 minute with balloons....let it cure overnight. gave it the same torture test....i couldnt break it free. and i also used the 45 degree strips per plans on the outside bottom/fuse /stab junction....only i drilled small holes with a pin vise in both surfaces before i epoxied them in. i feel this is as strong as the surrounding wood holding the structure together. you could over kill this area to your hearts content, but wont gain anymore than the wood will hold itself!

RE: Telemaster 40
Your method sounds close to what I had in mind w/o the angled gussets, do agree your's does sound like a solid assembly. Could you maybe, I know you can from what I have seen, maybe draw a diagram showing what you are talking about, I do not get the in-side!
|
RE: Telemaster 40
no need to draw up anything.....just put a small 45 degree gusset in every 90 degree corner you see in that area...then assemble and glue in the fin and stab. 90 degree corners are weak points....you will have to work around some areas of the fit to get this done. like i said....if you think an area is weak....add a 45 degree gusset....or maybe 4 or 5....on that line. its all about support. the strongest ultralights i done machine work on for the stress load in sun and fun in florida were constructed from chrome moly tubing. we triangulated every possible weak joing that had a 90 degree corner. you get the strength from triangles.

RE: Telemaster 40
When I got home today from work[:'(], I spied a big ole package on the front porch.:eek: Oh what could this be:), yea a Senior Telemaster from one of our own, thanks Mike.:D

RE: Telemaster 40
[&o] Oh, finishing up tail feathers, sanding and such, adding hinges. Once I am done, will move to the fuselage. Question, would you use or not bother w/a fuselage jig!:eek:

RE: Telemaster 40
no...dont need ajig.....

RE: Telemaster 40
Thought I would ask or should I say question the reason? I now have the Telemaster 40 and a Senior. Before I purchased either one of them, I ordered a set of plans from a dealer in Texas, these are a set for building a Tele 40. Now I have smoked over all the plans, 2 of which are included w/Hobby Lobby kits, and none of them are the same. Of course I understand the dif in scale, but it is as if the plans were drawn by different sources. Now they are all the same plane, but if you look close you will see they all are not the same?
Also, with the 2 Hobby Lobby kits, you get written instructions w/the plans, but I received a instruction booklet from the guy in Texas that is written w/photos. This one item has been of the most help. Just wondering why this did not come in the Hobby Lobby kits? |
RE: Telemaster 40
best to stick with one set of plans for the build. paper plans are not guaranteed 100% accurate. my 40 i built....the right half of the wing did NOT line up with the left half...in other words....you couldnt lay the 2 views together....and hold them up to the light and expect them to line up. its erors in paper shrinkage, and the printer. and my reason no fuse jig is its not needed if you build over the plans. if your plans are not large enough to build over a jig wont help you...you still at your judgement. most plans do not line up left to right.....least i havent found a set yet that does. take laser cut parts for example....lay them on the plans.....they are not correct. i find it best to just center them up best i can over the plan. its wood your working with anyway.....you always add or remove. hope this answers some of your ?????

RE: Telemaster 40
not sure about hobby lobby?......i dont buy there......they wouldnt sell telemasters last year becuse they said they didnt have any balsa.....thats bs. now they come out with a new version...see? they had the reason. i dont like hobby dealers like this. they can fool some of the people some of the time.....but not me. they are just middle men anyway....its all imported.
|
RE: Telemaster 40
Well in away yes, I agree, plans do draw up and expand. But I was pointing out something else! The out lay or drawing as rendered for ea. Set of plans I have has either a different detail for the same area or is drawn to reflect the assembly of a given subject, no 2 are the same in how they are represented! Does this make since. They all build the same plane, but none are drawn alike?

RE: Telemaster 40
I agree, build with the plans that come with the kit. I use the second set for ref only while building.

RE: Telemaster 40
yes...you can trust telemaster uk.....i had a video posted on that website of my build.....not sure if its still there or not? it would be under your telemasters...at the top. i cant give you an answer on your question about the differnece in plans.....everybody draws different i guess? i know that the incomplete kit i bought cheap.....only had a small book with small undetailed pictures.....it was totally worthless. had i i not had the plans....and years of building experience.....i would tossed it out the back door. all i can say is use your best judgment. its wood your working with not steel. you can do thing as you see fit rather its to plans or not. you will be ok. just make sure to get all the alignments correct. build straight and true.

RE: Telemaster 40
I built the Telemaster 40 many years ago and it does need reinforcing for the horizontal/vertical stab if you put a larger sized engine than recommended. I have an OS .55 AX 2 stroke in mine, which is great for climb performance with an APC 12x5 prop. I reinforced the tail by using an aluminum air-foiled tubing strut (K&S tubing) from the bottom of the horizontal stab to the under side of the fuse. Place the strut on the reinforced (blocked up) spar of the stab, under the fuse and up to the spar of the stab on the other side. Use Bolts through the stab and lags into the fuse. This strengthens the whole tail and the extra weight is compensated by the heavier engine up front.
Still have the plane and fly it frequently... Have fun with one of the best flying planes ever designed!!! Oly |
