    Motor Comparison

    Hi All, I have a question about trying to "compare" electric motors. I'm looking at buying a Balsa Cub Kit (Link) from Sig/Alien Aircraft. The recommended motor is a Himax HC-2808-1160 (Link). If I want to fit a different motor, what are the important numbers to compare (besides dimensions)...

    Help! Flying Rc Car

    Hi! I am thinking about trying a project to fly my rc car. I have a power pack C for propulsion and was planning on building the airframe around the rc car so that I could still drive. The car weighs a little less than 6 lbs, and I think the power pack C weights a little over a pound. I think it...

    Help! How much thrust on my flying wing airplane?

    I bought supplies for my first plane, which is the flying wing design! It is carbon fibre and will weigh 403 grams. The tricky part is the motor i bought supplies only 285 grams of thrust. My aircraft will have just over 400mm squared of wing space not including aerons. Will it fly?

    Help! Simonk ESC has a lot less thrust...

    Hi, thats my first post and also my first scratch build so I'm pretty much a newbie. I built a FT Mini F-22 and it was working great. For different reasons I now wanted to use another ESC and I bought a cheap 30A Simonk ESC from ebay. The problem is that with this ESC I have alot less thrust. My...

    FT Explorer with a Bixler 2 Stock Motor

    Hi there, I had a Turnigy Park 450 in my previous Explorer and it had plenty of power. Now I've built my second Explorer and I wonder if it can fly with a 1300 kv Bixler 2 stock motor? As this motor is not very powerfull I will not put any FPV equipment. Thank you all

    Tiny Trainer With No Thrust

    I recently finished building my first Flite Test airplane. I built the Tiny Trainer from their "Getting Started" package deal. This package deal comes with an Emax 1806 motor, Emax Bl Heli 12amp ESC, a 2 cell lipo battery, and a Spektrum DXe transmitter. I attempted a maiden flight today but had...

    Propulsion Systems

    Hi! I'm new and designing an aircraft at my university for a competition. I'm trying to learn more about the math behind propulsion systems (electric motor with prop, not doing anything with gas/glo). Does anyone know some good resources I'm missing out on? One that's been recommended to me is...

    Programming Throttle Disable Switch on Twin Engines with Differential Thrust

    Hello I could use some help. I am fairly new to the hobby and most of what I have learned is from the internet, mostly Flitetest and Experimental Airlines. I have build a couple of the FliteTest SuperBees. These have two motors and two ESCs and I have succeeded in programming in Differential...

    Rotary knob thrust limiter

    hello! any one know if theres a way to use one of the rotary knobs on the taranis, to set a maximum thrust? setting a fixed thrust value seems to be quite straight forward, but i didnt pick up how to use it as a max value yet the idea is basically limiting buddies that have never flown before...

    Kadet LT 40

    I'm building a foam replica of a kadet LT 40 I owned a few years back. I know it's a trainer plane, but it was quite a fun plane inverted three feet of the flying field. Anyway I have found enough info to get it looking like it's older brother but I don't know what size motor/battery to use...

    Can't get Punjet to fly. What am I doing wrong?

    I purchased the standard (recommended) Punjet setup from FT - the Power Pack A (Minis) and I cannot get it to fly. I am using the Loong-Max 800mAh 3s 20c Lipo Battery sold on FT, and the setup together doesn't produce enough thrust to fly. Also, I built according to instructions, and had to...

    Power Draw, In-Flight versus Bench

    One thing I've noticed in a lot of advice columns and articles is that most discussions of power draw are based on bench testing. Hook up the battery, ESC, motor, and prop, with a watt-meter in-line. Run it up, and check the power draw. Put it on a force balance and check the thrust. This...

    Thrust vs Power to Weight Ratios for Prop Planes

    I'm scratch building the FT Cruiser and would appreciate all the help that anyone can provide in designing the power system from the ground up. I know that I can use the parts specified by Flite Test but I really want to learn the fundamentals for future builds. I'm not into 3D flying yet so I...
