RE: throttle servo
I use good quality standard servo and good quality mini-servos and have had no trouble on medium and larger gassers. I have had trouble with lower quality minis mounted closer to the engine and I believe that was due to vibration. I have used a standard size servo on the firewall with no problems.

RE: Glow plug burning out on power panel
If you are plugged into the left jacks with the pot turned to the left and are blowing plugs then the glow circuit has failed and your getting 12 volts direct to the plug.

RE: Glow plug burning out on power panel
Do you have the glow plug leads plugged into the glow plug jacks and not the starter jacks? It's been done before and you send unreguated 12 volts to the glow plug. If it's connected properly and you have the dial set to low and it's still blowing plugs then your glow plug frequency circuit on the panel has failed. Putting a meter on the glow plug terminals of the power panel it will read 12volts regardless if the frequency circuit is working or not. It's not going to read 1.5 volts. It doesn't work that way. If you have a scope you can see what is happening. If you have electronic board repair experience you can repair the circuit. If not then you can use a glow stick or buy another power panel.

RE: Zenoah G-38 Prop Hub/Flywheel Problem
When you do that is the flywheel actually "rocking" side-side on the crankshaft or is the flywheel and crankshaft moving together in&out or front to rear a little bit A worn key or keyway would cause side-side movement on the crankshaft while the in&out movement is end-play and if severe could be a failing bearing or wear of case where the bearing fits. Was the engine in any crashes or did it experience any severe prop strikes when taking off or landing? Zenoah's are pretty tough engines. I have a few and never had any bearing issues. Seems the worst that happens to them is a bent crank after a severe crash.

RE: Lipo/ESC Connection question
Also, if you don't own one look for an amp meter. Either a good commercial multimeter,, convert a cheap harbor freight meter, or a purpose-built RC watt/amp meter. This can easily tell you have many amps and watts you are drawing from a motor&prop combination and you will know if you are coming close to or exceeding the ESC ratings.

RE: Lipo/ESC Connection question
You didn't state what voltage lipo(how many cells). The wire gauge difference won't harm anything as the heavier wire can pass more current. The motor will only draw what the load(prop) calls for and the ESC you have can only pass 60 amps. The prop you selected running on 5 cells should draw around 53 amps .

RE: Deployed flaps plane stalled and crashed
Well they make a difference on 30+ pound planes ! Plus I'm really starting to have fun with them after some practice on smaller planes. Ultra Stick with quad flaps doing short field take-offs and landings, diving down with crow and almost helicoptering in for a landing, slow fly-bys . Even on the new 60 size Meridian I'm having a blast with the flaps. I would say again to rebuild the plane after looking at it. With a non-computer radio you may have had too much throw by using the lever. Would have to limit max throw mechanically and find out how much flap it can handle by testing it up high going slow. You might have to manually input some down elevator when coming in until it slows down enough.

RE: Charging Lipo Batteries In Transmitter
Well yes that was as clear as mud ! I just read about that lipo and it's designed with a balance board inside the pack and it's not designed to be charged by a normal lipo-type charger . As you say it is specially made to be slow charged through the transmitter after the transmitter is programmed to lipo. You will need to keep the charger on for a very long time to fully charge and balance the pack. You are charging it with the wallwart charger so it's going to take maybe 20 hours to complete. Because the battery is specially made it can't be charged outside the radio.

RE: How old is too old for servo horns?
I have some planes that have been around for a long while and you can tell when the control horns, plastic clevis, etc...need to be changed. They get stiff, the color tends to change, and yes they can break. Depends a lot how the planes are stored as that can speed-up the aging process of those parts. I don't have an answer to how many years. If they look bad and feel bad then change them out.

RE: Deployed flaps plane stalled and crashed
Don't get discouraged. It takes practice to fly with flaps and the first part is getting the plane set-up properly. After you rebuild this one and take it up again, go up 2 or 3 mistakes high ,slow down to about 1/3 throttle ,deploy the flaps and see what happens. Typically the nose of the plane will balloon up a bit or it will balloon a lot ,or sometimes it stays straight and level, Depends on the plane. If it balloons up you have twp choices, either fly it with forced down elevator or preferably program in a flap-elevator mix where you can adjust the amount of down elevator applied automatically when you deploy the flaps. You take it back up in the air and lower the flaps again and test it. If it still balloons up then add some more down elevator. What you want to achieve is to lower the flaps ,keep the plane level and it will start to slow down. Once you have the mix dialed-in then go up again 2-3 mistakes high and see how the plane stalls with flaps down. Slow the plane down with flaps deployed and see how it reacts. Keep lowering the throttle until the plane stalls then increase the throttle and regain control. Hopefully the plane just slows down and begins to loose altitude. Some planes will slow almost to a crawl with wings level while others will drop a wing and start to spin. You need to find out how your plane will react and how much throttle it needs to keep flying. Landing with flaps takes practice. I'm still learning about them too ! You can't slow down too much or you risk a stall or you land too short on the runway. If its windy you usually don't come in with flaps. Rebuild it and try again !

RE: please identify this engine
Either regular pump gas and 2-stroke oil 40:1 or AV Gas and 2-stroke oil 40:1 is what I run. You would have to buy or make a prop hub to replace the stock flywheel and almost any electronic ignition could be made to work Here is a place that sells the parts If you convert to EI then the rev limiter has been removed. If you want to keep it stock I doubt that engine has one (non of mine had them) but if it did it wouldn't make much difference as on an 18X8 prop it won't go much past 7K except when unloading in a dive.

RE: New Evolution Engines!! 15GX, 20GX, 33GX
^^ Don't forget, the 15 is a ringed piston and the 10 is an abc so it will "feel" different. As the 15 breaks in the ring expands and contracts and it will "fit" into the liner. Then it will seal properly and you will notice a difference in the "feel" of compression.

I imagine you can get a little more out of the engine with the modifications he is doing but if it only gets it to the point of a 15cc then may as well get the 15cc engine! Still , it is interesting to look and see what he is trying to do. I don't think I would dive that far into it though. Weakest link theory and all. Start getting more power out of it then the next weakest part fails and you beef that up then the next fails, etc, etc....Before you know it you have redesigned and replaced the entire engine.

RE: Charging Lipo Batteries In Transmitter
How are you connecting the charger and what charger are you connecting ? As stated you can't charge through the transmitter like you did for NiCd or NiMh packs. If you have a charger that charges and balances lipos through the balance plug then you can charge it that way. If your charger requires both the balance plug and the output leads to be connected to the charger then you need to remove it and connect it up to the charger that way. I've had LiPo's in my transmitters for 5 years and I remove the cover, connect a cellpro4 via the balance plug and charge it . If you take care of the batteries, maintain them, charge them properly and monitor them(keep an eye on them) you shouldn't have any problems.

RE: Trying to learn but im terrible at math!
Maybe revisit this a minute. I suggest you read through this to get started:http://www.rcuniverse.com/forum/m_7100376/tm.htm If you want to start testing your electric set-ups you need at a minimum a watt meter for RC use. It connects between the motor and the ESC. As you try different props it will register amp draw watt produced, volts, etc The load on the motor determines how many amps it draws. The motor will continue to draw amps until it burns up so you have to be careful not to exceed that rating. Similar with the ESC it will pass current and if the current is too much it will cut-out and if it continues it will overheat and burn up...all based on the load of the motor. The batteries will give as much power as is requested until they reach their limit. As long as the motor can handle a 3-cell battery it doesn't matter if you connect a 3-cell 1000mah 20C or a 3-cell 5000mah 40c the motor and ESC will only draw as much current as the prop demands. The C rating on the battery determines the amount of current the battery can supply. Go above that number and you risk damage to the battery. So a 3-cell 2200mah 30C lipo will deliver around 66 amps . As lipos age their resistance changes (gets higher) and they can't deliver the amps as well. Different types of batteries have different resistance when new so a 2200 30C lipo made by one company may perform a little better than one made by another company . As they age or if they are missued the resistance goes up and they loose their ability to deliver the "punch". If you have the specs of the motor, esc, battery, you can use this to help determine what prop to use and see how many amps it draws, what power it can make, etc.. http://www.adamone.rchomepage.com/calc_motor.htm Other than that you need to start searching out electric flight , rc electric flying articles and read, read, read.

RE: please identify this engine
That must be where they are coming from then. With the cost of the newer chicom 30cc engines and how well they perform it's not worth it to buy parts to convert these engines . Now if you have parts lying around, or have a machine shop with aluminum stock and time on your hands then that's a different story. The Evra for sale above would be good for a 120 size cub, biplane, warbird to fly it scale. Just use it as a lugger.

RE: Trying to learn but im terrible at math!
Well, all the larger mah lipo will do is #1 add extra weight, and #2 give some added capacity or run time. If you want to try to push it get a 12X8E 2-blade prop and use a 1800 or 2200 mah 3-cell lipo. It should pull around 25 amps on the 30amp ESC. You can't push these stock motors too much as they aren't made that well. I ended up putting in a motor from the Parkzone Extra300 and the 3-blade prop from the Parkzone BF109. Looks more scale and flies nice but not overpowered.

RE: Spinner size ?
Typically you choose a spinner diameter that fits the front of the cowl on a cowled plane. Also it used to be a performance "rule" that you don't exceed 25% of the prop diameter for the spinner diameter. Otherwise you would be covering-up the part of the prop that makes the power. For example on a 10" prop you would want a 2.5" or less diameter spinner. As far as fitting the spinner cap/top to the prop, it depends what type of prop you are using. Some props fit in the stock cut-outs while others need the cuts-outs enlarged to fit around the blades.

I don't think it was BUT I never had one let loose however I never propped them to run over 8K. There is a Ryobi 30cc out there too that would be a conversion engine that is a bit beefier than the 31cc and can push higher rpms after conversion......closer to 10K. I never had a Ryobi 30cc so I can't say for sure.
