Default Air Hogs Titan Conversion

Hey ya'll
Im new around here,
For some time i have been wanting to get in to flying recently i have picked up a PZ champ and started flying that around campus at my college. Now i want something bigger that can handle higher winds that is still easily fixable due to the fact that I love flying in the wind ( weird huh I think its a bit more fun then just flying in circles and keeps you on your toes ) however the champ is too light for that so i have tackeled my first ever plane building project! I have picked up 3 Air Hog Titan gliders and i am going to make them electric powered. I have pordered the motor and most of the building equipments ill be using from hobby king. They should arrive by Monday ( i hope ) I will give yall an update when they come in.

They fly great! I just maidened my pusher powered Titan today and had a great time.

Mine has ailerons and elevator, the wings have been flattened and clipped at the transitions, uses an 1800kv Suppo outrunner, 7x5 prop and 1800mah 3s battery in the nose.
AUW is 180oz.

Awesome flyer

good luck!

that looks like a nice size foamie to try to modify, where did you pick that up? I haven't been able to find a titan at wal mart or target.

Still need to make the canopy and lettering though....

My dad has recently gotten into RC flying with me so I am going to make him a good trainer plane out of this airframe. I have started the project with the intent of mounting the prop on the nose. Seems like most people make this a pusher but tail mounting or on top of fusalage mounting. I want to power it with a brushless outrunner on a 2s 1000mah lipo (i forget my kv rating off top of my head) I am using an 18 or 20 amp ESC with it. What do you think would be a good prop size? The motor said it can run up to a 9x6 on a 3cell but i don't want to go nearly that big.

OK, with a guess that your motor is prolly 1200-1400kv roughly, and your plan is a slow flyer for Dad I would run around a 9x4.7 slo flyer prop on 2s. Put a link up as to the motor you are using and I can help you even more since I'll know all the specs of the motor

Thanks Ray, I was actually looking at it this morning I forgot to write it down, its tower pro 2814 i think...off the top of my head. I actually plan on using it for the short term in my airfield bf-109. I have to rebuild the motor mount and it will be alot easier to do with that tower pro motor with the x- mount than it will be to use the stock motor. I will probably just get another one for the titan project though or maybe try to use the airfield motor

this is my second fuselage attempt (was able to save wings and elevator from version 1) I had hollowed out too much of the nose and tried to use a stick mount and foam block that i glued back into the nose to mount the motor...when i powered up the prop for a static test tourqe was too great and tore mount out and nose apart.

If anyone has any comments on the tail feather sizing please let me know, I am wondering if I made the rudder and elevator surfaces too large. All the surfaces have a lot of throw on HI settings. The good thing is that since this was the second plane I now have a nice new set of wings that are un altered so i can swap out the clipped aileron containing wings to the stock wings and hopefully change quickly between a faster more aerobatic plane and a docile trainer. The plan is to give this to my father for father's day he has succesfully flown a few aileron planes but nothing fast and aerobatic yet. I am hoping this thing flies but may be a handful to trim out at first. The CG seems to be a tiny bit ahead of where the leading edge meets the fuselage at first it was very nose heavy, I then decided to make a battery bay futher back and that seems to help, I think a 1300mah 3cell almost makes it balance but I may need a larger battery or even some added tail weight.

Where do you find the CG needs to be? My first attempt at converting one didn't work out so well. I think my CG was too far forward. I had it a little over 2 inches from the leading edge of the wing.

I haven't done a lot of work on this since last post, but what I have done is cut away some foam under the rudder on the bottom of the fuselage and I hot glued two AA batteries there and then used some lightweight spackling to cover it up. The CG now seems to be maybe 10mm back from the LE at the wing root. My gut tells me it needs to be a touch further back especially with the sweep wing. I haven't attempted any flights yet since I don't want to total the plane before I give it away as a gift.

Well you can always test glide it. It should glide in a shallow decent I believe. That was my mistake. Also, I think I made the elevator too small so it couldn't pull up. If the CG is too far forward, I think you lose effectiveness of the elevator as well.

For the "rule of thumb" cg placement, measure the wing, divide by three, and at the first third, is where the CG should be.

Gave the converted titan to my dad for Father's day yesterday, weather was great so my dad, mom, girlfriend and I all went over to the field to test it out. I was afraid the ailerons and rudder had way to much through so i set them to 50% and left the elevator alone. I was not sure what to expect. we went out to the pilot's station my dad powered her up and i tossed her out for him. It was AMAZING, flew perfect required essentialy 0 trimming and was stable as anything we have flown yet. He flew the first battery and brought it in for a landing, even with the clipped wings it just floated down for a perfect landing. My girlfriend filmed it all on her cellphone so hopefully in the next day or so I can get that uploaded. My dad asked if i wanted to give it a try so after switching in a fresh battery and dialing up the ailerons to 65% he gave me a handlaunch. and boy was it fun, wind was prob a steady 10mph and the speed was decent going into the wind, quite quick downwind. roll rate was very good, inverted flight was sketchy...my design was not well thought out for quick manual trimming in the field and it doesn't have enough down elevator to work in inverted flight. but other than that its a great great plane to fly. There were a couple guys at the field and at first they thought i was joking when i said it was a 10 dollar glider i got at Target and converted. My Dad was like "no really it is". I bet we will be seeing some more attempts at this now from some other guys. I already have lots of thoughts on how to improve on this design and will be building myself one very soon.

Here is the maidan video of my fathers titan we took on fathers day, after seeing his fly I built another model for me with improved construction techniques.


you can see the other titan video I built too that I uploaded on youtube, only have 2 videos to choose from on my account right now.

Last night I added lights to my titan and snapped a couple pics.

Here is the video of my latest Titan, set up for nightflying. Haven't maidened her yet, was too windy at the field today to risk taking up a new plane.

Just finished this Titan EDF mod. I thought I would try to build a trainer EDF before I go crashing something expensive. It's got a 40mm EDF, 25 amp esc and I'm running on a 3S 850 mah lipo. Just ailerons and elevator. I'm going out for its maiden flight tomorrow. This is my first build. Any suggestions before I go fly it? It looks rough on the outside from all the measurements. I'm waiting to see if it flies before I paint it. The CG is about 5" aft of the leading edge, which is right about where it was when the glider was unmodified.
