ive just purchased a decathlon electric ive read on the forum about some upgrades that have been done to them ive just been to my local model shop and got e new prop its a Tornado 8x5HY the one on the plane is a 8x4 which has got a wider blade area than the one ive bought will this make a diffrence Cheers Ady

The original prop in your plane is designed to give good pulling power... kind of like bottom end torque in a good old truck but not a lot of speed. This is helpful with little hand tossed electrics as they need the initial pull to stay airborn. The prop you bought is going to fly the plane faster but will lack some of that pulling power. If you have some experience with the plane and know what it will do when you release it you may be able to get away with flying the new prop without incedent but it will be easier to fly this plane with the 8x4 prop.

Hi
Thanks for reply
im a newbie to flying planes i just read on the forum that the plane tends to need more forward speed and gentle up elevator or it tends to dip its wing and crash so i just thought id give it and myself a better chance to stay airbourn as quite a few people say its under powered and the other mod done to the plane is changeing the motor to a venom 370 and the prop to a 10x4.7 but as i want to learn to walk before i can run i thought i would leave the motor stock for the time being

A little more power may actually make the plane easier to fly. The Prop change is a crap shoot if it will be an improvement towards making it easier. I would sudjest holding the plane at full throttle and feel which prop pulls harder. Also try not to jam the sticks when correcting the planes direction. Give it gentle/smooth inputs and give yourself plenty of room. Do not try to fly in a confined space. This will give you more time to react with smooth gentle inputs. Start with big lazy circles then change direction and always launch and land into the wind.

Good luck, have fun, don't quit!

ok ill see which prop has more pull ill be flying in a nice big open park with no trees in sight i wont give up as i bought a cessna 46 i/c plane in the summer but i crashed that on my first flight into a chaps garage roof nose first after replaceing his tiles i got the plane back and had to replace the engine mount prop and spinner i put that to one side as i thought it looked much better in one piece so a few months later i thought id buy a electric plane and try to learn with that the chap at my local model shop said the decathlon was a good plane to learn on so i purchased it then found a few articles on here about it i should of searched the forum first then i might have chosen a diffrent plane but im a bit of a impulse buyer and it does look a neat little plane thanks again for your advice
