Hey Calixto, how ya doin? It's been raining and extra cold in Southern California the last 3 weekends, no flying for anyone. In addition, I have to work extra hard this time of year, I am a public accountant. This is how I make the big bucks to spend at Hobby Lobby. No weekends off for me, even if the sun comes out. I have a garage full of planes with fully charged Lipos and no time to fly. I am not a happy camper right now. I really need to get out and crash aa few planes so I can build some more. LOL Take Care Al

Calixto -> RE: Hobby Lobby Sr. Telemaster ARF (3/23/2006 1:02:35 PM)
Hi Al, good to hear from you again. I guess we are very lucky, we are in the middle of the dry season so we get to fly every week end, and some times we (the old guys) that don`t have to show up at the office every day, get to fly thursdays too. I have put about 20 flights on the Telemaster so far, it is a very fun airplane that even does some aerobatics and lands on a mail stamp with tlaperons. Well don`t make too much money and enjoy the hobby. Calixto

algutkin -> RE: Hobby Lobby Sr. Telemaster ARF (3/23/2006 2:22:53 PM)
Calixto: That little camera is sitting right by the computer, just waiting to be strapped onto the Telemaster. I'm really afraid that the end result will look like my normal family videos. You know, where the camera moves around and gives the viewers a head ache. Guess I could bring it to the office and take some pictures of the exitement, once in while my pencil falls off the desk, or the stapler gets jammed. The camera would also pick up alot of foul language and threats to elimiinate some of our troublesome clients. Actually the best time of day is between 10AM and 2PM, that's when DHL shows up with the Hobby Lobby or FMA order, also the US mailman comes with checks to be deposited. My retired clients call it "mailbox income" I think it would be fun to use the Telemaster to film another plane, while flying side by side. Today is Thursday, perhaps you could try it out. I've looked through Putfile and haven't seen anything like that. I'm sure it would work if the planes were slowed down. OH, I forgo something, next time you see one of the smaller cruise ships going through the canal, hold it for me. Take Care. Al

Calixto -> RE: Hobby Lobby Sr. Telemaster ARF (3/23/2006 3:49:58 PM)
Al. The film I took looking for my glider, came out very clear and steady, and the camera was straped to a 40 size Telemaster with a .70 four stroke engine, yours with an electric motor and a bigger airplane, should come out better. If I was in your shoes, I would go flying every morning, show up at the office at 10Am untill 2Pm to pick up the checks and the DHL or UPS deliveries, and go back flying in the afternoon, and have my kids or wife do all the boring work. I am training my family to accept that, either they will fire me from work and trow me out of the house, or they will learn, will see, either way I will have a lot of time to fly. Calixto

I'm building a hangar 9 J3 Cub. I've got a AXI 4230/16 I'm putting in. Kokam 3200 6S pack, a UBEC and a 15x8 prop. I hope this combo will work well. Larry

Greg Covey -> RE: Hobby Lobby Sr. Telemaster ARF (3/29/2006 12:25:15 AM)
Hi Larry, Yes, that combo will work well. It is exactly what my friend is putting in his H9 J3 Cub. Remember that you can use a 6v UBEC for no additional weight but your servos are faster and stronger. Hangar 9 continues to make the most incredible looking scale planes!

herm -> RE: Hobby Lobby Sr. Telemaster ARF (4/1/2006 11:00:05 PM)
aww!, sorry about that Mike.. Herm

algutkin -> RE: Hobby Lobby Sr. Telemaster ARF (4/2/2006 12:32:40 AM)
Mike, I'm real sorry to hear about the wing failure. I was looking forward to seeing movies of the bomb dropping. I have a son, much older than yours, and many things similar to your joint building project have happened to us over the years. We felt really bad at all of the unexpected failures, but, they did nothing but to strengthen our relationship, instead of hurting it. When he got older we built RC helicopters together, some crashed, then we souped up and swapped engines in his first trucks, some engines didn't make it, then we got into dirt bikes, then we hopped up jet boats for the river, now it's building a sand rail for Glamus. In all those projects, there were tears expended by both of us, there were angry fights, however the one thing that survived it all is the friendship of father and son. It's OK to shed a tear, kids need to see that their parents are human. Al G

acemace16 -> RE: Hobby Lobby Sr. Telemaster ARF (4/2/2006 4:49:20 AM)
Mike and Al, Sorry to hear about the crash. I know how your sons feel, my dad crashed my Sr Telemaster on landing once and I had to rebuild it. Luckily it wasn't as bad as a wing failure accident. I'm still flying that same Sr Tele 25 years later with the original covering on it! A few years ago I converted it to electric to fly at SEFF #2. I'm now building a SR Tele ARF for SEFF #5. I'll get some pictures up soon with some stats. Dave P.S. Hobby Lobby is giving away 2 each Sr and 40 Telemaster ARFs In the raffle at SEFF this year!

MikeFreas -> RE: Hobby Lobby Sr. Telemaster ARF (4/4/2006 4:14:35 AM)
Al was kind enough to offer me a new ARF and I'm going to go pick it up this week. I plan on starting a new thread documenting the mods and to say thanks for an act of generosity.

RickF -> RE: Hobby Lobby Sr. Telemaster ARF (4/26/2006 5:33:35 AM)
Hi everyone, I have been silently following this discussion for some time, and am happy to report that my TM will hopefully make its maiden voyage in two weeks, weather permitting. I am new to electrics, and am having a tough time wading through all of the different LiPo packs and specifications available. I could use some help! I have the Axi 4120/18 motor with the Jeti Advance Plus 70 amp Opto controller. Prop will be the standard APC 14x10 eProp. The LiPo pack I am considering is the "Twenty" PQ44004 4 cell 14.9v 4400 mAh pack, along with the PCM Guard for 4s LiPo packs, and the TPC425 charger. Like I mentioned, I am new to electrics and am not totally sure if this is the right direction to go, LiPo wise. I am also concerned that this is the correct charger to use. I am willing to entertain any other ideas from more experienced electric users out there. I am sure that there are many, many more combinations out there that might be better, and any input will be greatly appreciated! I am also working on several ideas for mounting the wing struts. Sure wish the manual touched on that. I will also post pics of the finished airplane on the ground and in the air. Thanks, in advance, for your help! Rick Santa Ysabel, CA

herm -> RE: Hobby Lobby Sr. Telemaster ARF (4/26/2006 3:18:26 PM)
You already bought the motor?, it seems to me that 4 cells is too low, Hobby Lobby calls this a 5-7 cell motor.. it will fly well but with a kind of anemic (in my opinion, many people would be satisfied) climb rate.. your setup is around 500 watts. Bump up the prop to a 1610 E apc, this will boost power to 630 watts, 45amps and about 60 watts per lb.. even better go to 5 or 6 cells and a 800-1000 watts. Your esc can handle up to 6 cells so that is the limit, good choice of esc btw. 4 cells, 33amps, 1410 prop, 475 watts at 50watts per lb 4 cells, 45amps, 1610 prop, 630 watts at 65watts per lb 5 cells, 48amps, 158 prop, 820 watts at 80watts per lb 6 cells, 44amps, 138 prop, 920 watts at 90watts per lb 6 cells, 49amps, 147 prop, 1000 watts at 100 watts per lb two 3 cell packs would give you versatility, you could use each pack individually in a 40 class plane, or both of them in the TM I dont know about the 425 charger.. can it do 5-6 cells (otherwise it will limit you in the future)?..if not consider the hyperion chargers or the astro 109.. instead of the pcm charge guard get the more versatile hyperion lba6 balancer/charge guard.. it will stop the charger if any cell goes overvoltage and also balances the pack, and it plugs into the battery you are considering. I own one and it gives me peace of mind when I charge my packs while I am sleeping. It is a better deal than a pcm charge gard. 400-500watts is about the power of a sport 40 glow engine (old K&B ringed 40), about what the senior TM was originally sold for.. very gentle. Herm

RickF -> RE: Hobby Lobby Sr. Telemaster ARF (4/26/2006 5:28:56 PM)
Thanks, Herm, for the advice. Based upon what you noted, I've decided to change my initial direction. I am thinking BalancePro HD 3200 1P6S along with the DPM set up for Opto, and the charger will be the BalancePro HD6S. From everything I have read lately, this seems to be a pretty sweet setup. A bit pricey, but I want the power and flight times. So unless I find anything better and less expensive, I will order tomorrow morning. Rick

MikeFreas -> RE: Hobby Lobby Sr. Telemaster ARF (4/27/2006 1:50:38 AM)
Well you have the exact same set up as my now dead TM. Before you go and buy a 6S pack take a look at this set up. I easly got 45 minutes of flight time using your exact set up and a 5S2P 8000 mah pack from TrueR/C. This pack sells for just 165 bucks. Now it's only 5C discharge rated but you don't need anything more for flying the TM. As for the charger I got one of the 79 dollar chargers from Dymond modelsport. This little charger charges every pack I have and I have never had a problem with it. Any set up above 5S will cost you more in the charger department also and most forget that. Now if your wanting a 1000 watt monster to tow gliders then this set up is not for you. I flew my TM with a large digital camera with an AUW of 11 lbs without a problem. Think about it. You could be flying for less then 300 bucks and have enough money for another pack! When I buy my new packs for the TM I'm going to split them up and buy 2 5S pack instead of two. Just another option for those of us with shallow pockets.

RickF -> RE: Hobby Lobby Sr. Telemaster ARF (4/27/2006 2:42:26 AM)
Mike, Thanks for the info. I was able to find the Dymond charger, but so far have been unable to find anything on the 5s2p 8000 mAh pack. Suggestions? Rick

flyifr -> RE: Hobby Lobby Sr. Telemaster ARF (4/28/2006 12:32:27 AM)
Good evening...now don't laugh but I plan on putting a spare saito 180 in it...power management is the key, long flights at 1/4 throttle. I am pretty sure the CG is going to be out with the weight of the Saito, easily fixed. I am not too fond of the wire gear and would rather have an aluminum or carbon gear, any recommendations. Also I read on the thread about bigger tires, better landings, how big is bigger guys. I agree, struts are necessary. I don't like the rubber band trick and see many ways to make bolt on. Recommendations for the most non invasive way you think with the ARF? Is the trailing edge stout enough as it is to drill and hold the trailing edge down, naturally with some hardwood mount in fuse to attach to...securely mounted too. From what I read and I have read all 7 pages, the extra rib approach seems the best way as you don't have to cut into a perfectly covered wing panel unless I misread this approach. Thanks for all the work on the thread on the ST ARF, answered a lot of questions for me, before I thought to ask them. Kit arrives tomorrow...can hardly wait.

algutkin -> RE: Hobby Lobby Sr. Telemaster ARF (4/28/2006 12:59:23 AM)
Flyr: I can't help it, but I am sort of laughing. This is the conversion thread, are you planning on converting from electric to Gas? Darn, if you put a SATO 180 in it, the thing will probably fly like a you put in a Dodge Viper V10 motor. Heck, it might hover. Re: wing hold downs, there are at least two methods of modifying the wing for a screw in hold down in this thread, my method is so simple, I can imagine any other way. The ARF's wings go together with two hard wood spars, there is not much of a chance of the wing breaking in half. The wing broke on Mike's Telemaster because he made his from a kit and I don't think he used hardwood spars. The screws don't add any more presure than the 16 or 20 elastics that the kit requires, and spare yellow covering is included in the kit. The elastics hold so tight that they actually might cause more pressure than the nylon screws. Anyhow, keep us informed, you should have the kit completed within one week, so, I, for one will check back on your progress. Based upon your success, I might just give my Axi 4130/16 the heve ho, and go to nitro. I just love those 4 cycle SAITOs, last month I sold 4 of them on Ebay, and converted my Hangar 9 planes to electric. They don't sound as good, but they fly and my nitro rash went away. Al G. (take this post with the humor that was meant when I pushed the OK button)

flyifr -> RE: Hobby Lobby Sr. Telemaster ARF (4/28/2006 10:09:56 AM)
Algutkin: Ok, laughing is allowed, I was as I typed. Yeah, I hate the residue of flying nitro, but I am hooked on it now after 25+ years of doing it., and the sound of 4stroke is intoxicating. Thanks for the input on the wing hold down. Great thing about "maturing" < grin >.....ya just don't care as much about outcomes. I remember back in the day when I would spend months buiilding, covering, painting kits, now if you end up with a day at the field with your stuff in you McDonalds bag along with the left over fries, well you just pick up another ARF and do it agian. Have a great day and I will respond back after my over powered ST is in the air.

Calixto -> RE: Hobby Lobby Sr. Telemaster ARF (4/28/2006 1:45:22 PM)
I used the extra rib method, and it works beautifully, there is no problem with the trailing edge to support the hold down screws. I used a Magnum 91 four stroke with a 15x5 prop and 25% nitro, it climbs out of sight at an 80º angle. 4" wheels work great, the struts will make you a lot more confident if you do some aerobatics, I strongly recomend you increase the rudder area by 50% at least, with the stock rudder, you loose yaw control al low speeds, and it will take a couple of turns before coming out of a flat spin. it will fly inverted with no porblems dialing in a little spolerons.

algutkin -> RE: Hobby Lobby Sr. Telemaster ARF (4/28/2006 3:05:19 PM)
Why we Fly Telemaster Electrics: Typical day of flying nitro, Pack all ths stuff into the vehicle, nitro fuel, fuel pump, adjusting tools, big battery, electric starter, lots of custom made cleaning fluid, or Windex. Last but not least, rags and paper towels. Next, get to the field, unload the vehicle, and clean up all the stuff that spilled and stained the carpet. Pump fuel into the plane, ooops, some squirts out and gets on your hands, arms, and clothes. You grab a rag or towel but that just smears the stuff even further. While you are bending down, your glasses slip down your nose. When you fix them, there is a nice large oil spot on the lens. Again, a clean wipe with a rag just smears the spot, now, you only can see with one eye. OK, check everything, grab the starter, trip over the starter cord and things get disconnected. Anyhow, after 1/2 hour of screwing with the starter, glow plug, fuel, and dirty glasses you finally get that baby to takeoff position. First try results in a stall, the humidity changed and the mixture needs to be adjusted. Now, you must get the help of somone else to hold the plane while you adjust the mixture. The problem is, that the new helper really wants to talk, talk, talk, and give you lots of unwanted advice. Now you have a airfield buddy that just won't leave you alone. When you finally get the plane in the air, it's torture when the knats and other flying bugs just stick to your oily glasses. The best part of nitro, if you don't crash, you get to do it all again. Maybe that's why I loved to crash nitro. Lots of smoke, a reason to go home and get free of my new talk buddy, a reason to take an extra shower and wash myself down with alcahol. Actually, it was a reason for me to quit flying RC for over ten years. Now, I like electric anything RC, cars, boats, airplanes, TVs. I'm a much happier person with electric and I love my Senior Telemaster with nylon screws holding the wings down, I love my Decathlon with screw hold downs, I hate elastics breaking and snapping on my fingers. NO ELASSSSSTICS.. Al G

Calixto -> RE: Hobby Lobby Sr. Telemaster ARF (4/28/2006 4:04:29 PM)
I have some small electrics to fly close to home, but nothing beats the sound and smell of nitro engines, silent powered flight just doesn`t feel natural. Because of the heat and humidity in Panama, I have to take a shower when I get home anyway, otherwise I would be hearing a lot of static the rest of the day and into the night from the wife. That is the good thing about this hobby, no matter what your tastes are there is something right for you.

herm -> RE: Hobby Lobby Sr. Telemaster ARF (4/28/2006 8:12:11 PM)
Calixto, can you describe exactly how you get into a flat spin?, also your CG location.. my TM arf wont do anything as exciting .. Having an electric plane is never having to clean it.. I'm proud of the 3 year old mud and grass stains on it :) The smell of castor fuel on a hot sticky day is enough to upset my stomach, and then I gotta run looking for a toilet.. I can tolerate it in the winter but not in the summer, the problem is that all the newbies at the field want help adjusting their glow engines. Last time I owned a glow plane was back in 91 I think.

flyifr -> RE: Hobby Lobby Sr. Telemaster ARF (4/30/2006 10:24:05 PM)
Thanks for the info Calixto ie: wing hold down and wheel size. Mine came with what appears to be 4inch wheels ( light foam type ) per my tape measure. Any of you folks seen a STM setup as trike rather than a dragger? See any reason why NOT to do this? You folks were correct, build documentation is pretty sparse, but it is pretty well built for you already. I am not big into advertising, anyone have a kind way to pull off all the decals ie: Hobby Lobby as well as all the others. Sure wish they had left those off and let it be an option to put on if you wanna. I am not much into dihedral. Knowing I can replace the joiner spars for straight ones, any nifty ideas on how to fill in the gap left by the dihedral if making the wing flat? I guess add another thick rib and sand it down until the two halves touch/mate. Any better methods/ideas?
