Man I've still got a smile on my dial from this morning. Not sure about average speed of passes choopi-I tend to break up my flights with some very tame tricks and inverted flying, not just rocketing around. The few really fast passes were all over 200km/h. The temp reading was spot on-just used the auto function. Wind was around 7km/h.

I'll try again with an average over the next few days. How my passes do you need for a speed to be respectable? I might compare with the APC 6x4 prop also. I'm telling you though, get onto graupner props. They are sweet.

Just one! Pretty accurate all the time! It's fast that is all there is to say!

Would a 1300mah 4 cell fit in this thing pretty easy?

Hey guys,

Great thread and it's sold me on a Radjet! After reading from start to finish I'm nearly decided on my set up but had a couple of quick questions.

I'm going for speed here and like the sound of the 2836 - 2350kv Turnigy on a 4s nano-tech 1800mah BUT Has anybody run the 2386 - 3200kv?? This motor is lighter (72g compared to 79g according to the king) and has the ability for 5s

Also i see most people are running a 6x4 (or Pete's 6x4.5) prop but there are a few comments about 4.5x4.5 and other smaller ones earlier in the thread. Can anyone suggest the best prop for speed for me.

Sorry for the questions but I'm a nitro heli pilot who dabbles in planes so props and electric motors are not my thing - UNTIL now that is!

Any help would be great.

Cheers
Mac

Hi Kiwi. I don't actually have a radjet but a skyfun-think it's s bit bigger than the radjet and can take more weight. I would have thought that you'd lose too much rpm with a 6x4 prop powered by a 4s 3200kv motor, compared to say a 4.7x4.7, which would have a much higher rpm.

I have the 2836 2350 in my radjet and while i have only tried it on 3S i am pretty confident that it will blow your mind on 4S.

Thanks Pete. done a bit more home work so getting the hang of the motor / prop thing I think. So how would I tell what's going to go faster? The 3200kv with 5s and say 4.7x4.7 or the 2350kv on 4s and 6x4? Is there any set formula or is it a after of experimenting?

and cheers nogas good to know. Pretty sure I'll run your setup as it seems pretty popular

on the crazier side anyone got near 300k/hr out of these? Any suggestions to get one there?

thanks guys

thing is it's not a simple yes or no. Its a yes but you need to get rid of foam to make it a yes. flick back through the thread and you'll get your answer with some other helpful advice.

I did read the thread. I saw about a 1000mah 4 cell but I didnt see anything about a 1300mah 4 cell. that is why I asked. I would like to know what a good battery would be that wouldnt require a lot of foam removal. some is ok, but I dont want to remove a lot.
