    Hempel 50CC Yak Prop suggestions??

    Hey Guys- Been out for a while, hoping to get back into the air.. I have a 50cc Hempel Yak, with a DA50 on it.. I was running a Zoar prop, but it was pretty weak.. Any recommendations for a good general purpose prop? Flight style is beginner, basic IMAC and beginner 3D.. Thanks...

    DW Foamies 48" Yak 55

    Mike, Do you need testers for the micros? I suck at building, and I suck at flying.. Makes for a great tester, right? :-)

    DW Foamies 48" Yak 55

    I drink a pint of lube before flying, does that count? I am also using cheap 20C packs from Hobbyking.. I am only getting about 8 minutes, and using about 1900mAh from a 2200mAh pack.. I wonder if these are truly 20C, maybe they are a weak 20C? Oh well, $11 including shipping, I figure I can...

    DW Foamies 48" Yak 55

    Hmm, still confused.. I always took the inverted 45 deg climb as a pretty good indicator of proper CG.. Granted 'proper' depends on what type of flight you intend on doing... With my plane pulling towards the canopy during this test, it would appear to be nose heavy.. My limited experience...

    DW Foamies 48" Yak 55

    Is that a misprint? I checked with DW on the CG, and they verified the manual had a misprint, and we should be using the spar location (which may be 2 3/8 behind the LE). With CG on the spar, I can't hold an inverted 45 deg climb (tucks to canopy), and knife edge requires a little nose up...

    DW Foamies 48" Yak 55

    I didn't take any video, but I think I need to fix that.. No, do not use the CG from the manual! I talked to DW about the CG in the manual, and it is a mis-print. They are issuing another revision of the manual to fix that. The proper CG for the 48" Yak 55 is on the CF spar. For my first...

    DW Foamies 48" Yak 55

    Sorry, not sure where this should go... I failed to do a build thread, we were too excited to get the planes together to stop and take pics :-) Anyway, I have read a lot of reviews, and rarely do I see a negative one. After awhile, I start to question all the good reviews.. I started...

    Jomamma- Was yours a 50cc? If so, the price is low enough you might be able to just replace it :-) Otherwise, maybe Bill will jump on this thread and let you know about parts availability.. Lectrictech- I thought we purchase directly from Bill.. I just checked his site, and it looks like...

    Another idiot....

    I used to play with Hot Air Balloons a long time ago.. Our pilot warned us about this same issue.. Seems powered aircraft like to take a spin around the big dumb balloon, but the size is deceiving, and they tend to get too close.. Our pilot (Active ATP, and Helicopter Instructor) had an...

    Whats a better hand crank fuel/smoke pump.

    Again, sorry, not sure about smoke compatibility, but here is the thread I started on the slimline can.. I thought I was using the slimline hand crank on SuperDri oil with no issues, but that was a few years ago.. You might be able to call Slimline, last time I called they were helpful...

    Whats a better hand crank fuel/smoke pump.

    Oooh, I got a great one for you.. Slimline makes a really nice setup, sells you the can, the pump, and a nice machined mounted for the top of the can (pump mounts to a block that threads onto the can nozzle).. Sorry, that sounds weird, but it is a nice tight setup, and if you use one of...

    New from FG?

    Hmm, I must be a little stooopid.. Took me a few tries to figure out the hidden agenda behind Howie Felterschnatz.. Got a good laugh out of that one though :D I was wondering two things.. #1- With all the new regs on FG, can they really still call one membership, or post level "Bad...

    BH 50CC Yak 55 build

    Wow, has it really been two months since I last looked at this thread? Finally got to fly her on Sat.. Just two quick hops.. Had to add about 20oz to the nose to balance her at the back of the wing tube! Overall weight is about 18.5 if memory serves.. I don't think I can move anymore...

    Iron Corps Charging

    Sorry, last one.. Just one more confirmation.. I use the TP 610C charger.. This was listed on their website for a similar charger (1010C): Charge mode for LiFe (A123): Topoff charge: 3.65V per cell Over voltage error: 3.85V per cell Initial slow charge to 3.0V per cell LiFe (A123) recovory...

    Iron Corps Charging

    T-Man, What charger are you using? Attached (hopefully) is an interesting PDF I found on FMA's website. It shows the max voltage per cell at 3.7V, we should probably use 3.6 to stay clear of the damage zone.. Anyway, check out this PDF, from previous discussions with you, I think it is a...
