Payloads and blade size and rpm??

[MaSt0RaS]

Hello guys i want to hear your opinion about what payloads are the best for each blade size and what rpm..

What is the optimum payload and rpm for 600 what for 700 what for 750 and what for 800??

I have 750 and my weight is near 9 kilos but i think i have to add some weight what do you think?? I am on 1650rpm

There are many variables to consider, such as airfoil (sym, semi, flat bottom), available power (from the motor), Temperature, and altitude, to name a few.

Available power makes a big difference, an 800mm Single cylinder Gasser can carry 12-15 Lbs typically, but our Industrial Twin with the same blades can carry upwards of 25 Lbs.

12 cell electrics are producing amazing power, just be sure your drivetrain is up to handling that power when carrying payloads.

We typically spin our 800mm bladed machines between 1450 and 1650.

I know that there are too many variables... But i want to here some opinions like yours...

Difficult to answer, Here is what I ran on a few machines but ultimately you just have to find each machines sweetspot. Even if you put two machines identicle to each other you could still have a variance of headspeed to find the sweetspot.

ANyways.. I ran a GSR 260 with payload at 1450. Without payload at 1350. 810mm
Bergen EB I ran between 1450 and 1500. With or without payload. 800mm
Logo 600se I run with payload only. 1320 on 710mm

Just from looking at my Logo figure highlights what I am saying. If you asked most people who didnt fly one...they would say..hmmm 710 or 693 blades.. around 1700rpm? My Logo flies with authority and sharp response (definatley sharp enough for AP) at that low headspeed. I have even ran it as low as 1200rpm. Bit too soft then and got the horrible wobble effect on my camera.

You need to play.....its all I can say. Each machine is different. Also dont listen to a 3D flyer for AP advice...unless obviously he does both.

Quick cheecky plug.... My GSR is up for sale http://www.aplanding.com/forums/show...4797#post44797

Can run 900 ASYM blades @ 1100 HS and carry a 28lb load

pls tell us here the overall weight of the Flying AP machine..!
Thank you!

I do both

MaSt0RaS....

Quick question... is your Logo whats carrying 9 kilos?

If it is.. your pretty damn close if not well over its capabilities. Keep a close eye on all parts. Stretching it doesnt beef up its design capabilities. Really for 9 kilos you need to be on a machine that was built for 800mm blades as standard.

If your not using it... just ignore me

My logo with full payload come in at 6 kilos.

If your inquiring about mine... if I were to remove the cameras already installed, 13 1/2 lbs or less AUW

Yeap it is near 9 kilos.. its something lke 8-9...!

I have 750 blades...!
It doesnt have problem..! on 3ding the 4 kilos is something like 15kg...!

Only my camera and lipos weight 2kg the 6600 lipos and 1.3kg the camera ..!
3.3kg + 3.5heli + 800gr gimbal +400gr rec lipo + some more like Vtx bec etc i am near 8.5 kilos..1

I am sure that for 800blade machines you must have 11-12kg not 9-10..! Remember AP machines are for calm flights..!

[madmcphil]

Keep a close eye on it.

If I were carrying 9 kilos and kept electric.. I would choose a Maxi Joker.

My friend has a Maxi Joker with 800 and its over 11.5 kilos..

It doesnt have problems..! a heli that is doing hard 3d and weighs 4 kilos can easily do a calm flight with 8-10 kiloas..!

I only fly AP.
800 Machines can be used for any weight, light or heavy! Logo with 9Kg plus extended 750 blades @1650 in my honest opinion is asking for trouble. At least change the rotor head!

This is only my advice....you are free to take it or leave it.

This rotor can handle 690 blades and 700 on 1950 rpms with HARD manuevers and cannot handle 750 on 1600 rpms calm flights???

Thank you for your advice but it can..!

It can handle these flights and not a calm flight with 9kilos.. on tic tocs and on stops the machine is like being 15-20kg..

THis is the same heli i changed bearigs and some other things and i use it for AP


PS Also i want to here and some more opinions on this. .

[madmcphil]

Didn't say it couldn't do it... Just advised against it. If it were me I would get the right tool for the job thats all.

[PhotoShip One]

Just thought I'd jump in and say we've flown the stock plastic Logo 600 flybar head on an 800 ship at up to 23lb for the past 4 years with never a rotorhead failure. The only modification we did was to the one way hub in which we custom made a hub with two one way bearings stacked in the hub instead of the typical one in a stock Logo hub.

I know of at lest 3 other customers of ours who have been doing the same.

The stock Logo 600 head is well up to the task if 4 years of flying means anything. Just keep the headpseed under 1400 on 800's.

[madmcphil]

Ok... I'll concede,

I apologize for any miss information that I may have given. I truly believed that 9Kg of payload with 750's on a standard 600se was asking a bit much of the plastic framesets and plastic rotor grips and drive train.

4 years of successful flights cant be argued with.

My apologies to MaSt0RaS, I didnt mean to upset just wanted to put across a concern which was unfortunately inaccurate.

[PhotoShip One]

No need to apologize. You had right to ponder the integrity of a plastic head. Certainly it is true that an aluminum head of the same size would be stronger than plastic.

No problem my friend..

Do you sell them??
