Thread: Incidence Meter/Gauge Measurement
31/08/2019 01:32:08

I have always used the old Robart unit with the little needle that swings. I understand there is a new unit with a screen and digital read out,but have never seen one. I have a friend ( odd, is it not) that uses what looks like what Cuban8 has in his picture, and he uses it to set up machines for metal work. I bought a similar unit , which looks like what Cubban8 has in the picture but got it from the model train people. They use it to set up grade incline for their train sets only it reads in percent grade. 45 degree angle is 100 present grade. Just got it.---Bob in KS

Thread: High Start Beginner
26/08/2019 23:35:09

Hello, for years I have launched my Bird of Time,( 3 meter) with my high start out here in the flat lands of Kansas. 100 feet of 1/2 inch OD surgical tubing and 400 feet of kite string to great effect. What I was wondering is just how big/heavy a sailplane I could get away with using this set up? Or just get into elec launch from the start? I was looking for something more scale. Anyone using this kind of High Start for something that had more weight?----Bob C

Thread: Hitec Optic 6 2.4
03/08/2019 05:56:33

Hello ALL---Maybe someone can explain an issue with my Optic 6 Sport? I could not get Hitec on the phone today, will try again Monday. The instructions say to never have the trans on when connected to the wall charger. My on/off switch is rather loose and easy to move either way. When taking it off charge , I accidently turned it on while still plugged into the charger for a few seconds. Is the problem with heat build up if leaving thus connected ( as when setting up a new model), or an over voltage to the circuits and thus damaging the trans? I'll try again with Hitec Monday, but would like to fly this weekend and am worried if I melted something. Any thoughts? Thanks in advance.---Bob C in KS

Thread: Hitec Optima Aerial Mount
26/07/2019 04:13:38

seems I have more planes than receivers. Now using Hitec Optima 6 sport equipment. I plan on mounting one on a piece of light ply. I have never really noticed any getting hot after a flight but did not want to mess up the case area exposed to air flow by doing so. I plan on mounting one on its side to expose the bottom and attaching it to the fuselage with 2 magnets. Easy to move from one plane to another. Magnets don't affect the rec, do they? --BoB in Kansas

Thread: Litho plate substitute?

OK , just what is LITHO Plate anyway? I imagine thin , easy to form sheet metal? Balsa I figured out years ago and I even know what glue is but,---litho?

Just wondering. With freq hopping ,just how many hops does it do in a second.---Bob

Thread: Hitec Flash 8 Battery Life
18/07/2019 08:54:58

I have a Hitec Optima 6 Sport which has a low trans voltage warning but only for NiCad and NiMh. To use a LiFe I need to program it to accept this. The instructions say I need some kind of equipment, possibly to go through a computer. I can not find any reference to this anywhere. Does anyone know about this?---Thanks--Bob

does anyone know if Great Planes still have the Sportster 40 twin?

Thread: What setting for charging NiMH batteries
14/06/2019 04:40:19

I have a 5 cell,AA nickel Eneloop batt pack rated at 2000 MAH. Two quick questions: The Mv trip point does not seem to fully charge the pack if set to 5Mv. If set to a higher number, it comes off the charger at 7.4 V and a little warm. What's a reasonable number? The discharge point I have set to use while checking the capacity is 1.2V. While doing a capacity discharge check, should I set the voltage to something lower , or is 1.2V about as low as you would want to get a nickel to?

Thread: Glow Sticks
11/06/2019 08:11:29

Graeme, How long is the wire between the batt and the plug? Or are your glow plugs doing OK @ 2 volts? Wire would, of course, drop the voltage a bit.------------Bob C

Thread: Model Noise Level - Interesting Findings
11/06/2019 02:59:05

Is this why a four stroke is, for me, perceived to be quieter and more pleasant to the ear. I am wondering if it would record the same level of sound as a 2 stroke? One half the power strokes= lower freq and therefore seems quieter?

Thread: Charge currents
19/05/2019 00:51:49

My son ran into a situation lately that puzzled me. he has 2 twelve volt batts in series for 24 volts. I believe they are LiFE .

This was for a power drill. Not A/C related but I figured it is the same chemistry. Taking it off the charger, he separated the two 12 volt batts , and the one measured 35 volts! How can this be? What is going on here? Any thoughts out there?----------------Bob in Kansas

In some of the more recent RCM&E additions there were mentions of two books. I am currently partly through "Bristol Scout 1264" and I must say it is a good read. It just now came into the US so maybe it has been out for awhile elsewhere. Also the "High hulls flying boats" looks interesting too but I have not cracked it yet. 25 pounds for the Scout and 40 for the flying boats one. It's only money! Bob chamberlain

the Super Sportster would make a nice ship, I think, but it has been awhile since I have seen a kit. I think there is an ARTF out there somewhere.

Thread: Hitec
25/04/2019 08:35:19

I just do not understand this deal with Hitec. The above posts are over a year old. Is Hitec really not going to keep offering transmitters? Or is this old information? My hobby shop here in the US says he can not get any Hitec trans! Just what is the real story?----I am off now to the Hitec site to see what I can find out. Maybe should have done that first instead of asking here. Sorry for silly question, it's late---Bob

hello all,--- what "after flying" cleaning fluid do people find works the best for them for glow/oil engines?

Thread: A simple problem
02/02/2019 07:38:59

sometimes my "Nistarter" gets a little low by the end of the afternoon. This is the kind with the batt and little meter that pushes onto the glow plug. I still have my good 12 volt batt on the tool box,--so how can I give the 1.5 glow starter a charge up from the 12V? I do not have a power panel. Resister of some value?---or for that matter, instead of trying to recharge the Nistarter, just run a line from the 12 V with a long voltage dropping wire and/or big resister? Of course, I guess I could just but 2 Nistarters! ---Thank you,---Bob in KS,USA

Thread: Identifying Laser Engines

I am looking into something like a WW1 bi plane for my next project and am looking at different four stroke engines that might be applicable .Any thoughts out there? How about kits? Flair, BalsaUSA, Proctor? I live in the states. Thank you,----------------Bob Chamberlain
