Default RE: E-Flite Electrajet

Yea I have flown her a couple dozen times with the brushless setup... And yes I would say I am getting somewhere around 50-60 mile speeds easy now...

The reason I went for this setup is I wanted to trim weight... The Electra jet tends to be tail heavy so I decided to go with a direct drive setup to lighten the tail and the whole plane some... My plane with an 8 cell 2/3 1200 pack weighs in a 17 oz... Yea power to weight ratio is just awesome...

I am running a 6x5e prop on her and vertical is pretty much unlimited other then the size and color I don't let it get to high... You should see my high speed passes they are awesome and the brushless motors have this really unique high pitch sing to them that really makes her sound like a turbine powered plane...

I need to see if I can find someone to capture some video on a high speed pass and I will put it on here...

Anyway all I can to say to anyone with a Electra jet is get a brushless setup and you will be amazed as they have been at my field how a little foam plane can hall some much tail!

Oh BTW my flight times are in the 7 minute range depending on how I handle the throttle... I tend fly fast so I am guessing a moderate throttle would get 10 minute flights easy...

I really thought a whole lot about using a gearbox but I have to thank my motor supplier for suggesting the 16/15/3. I was telling him I wanted a really light gearbox due to weight factors and he told me that a lot of flyers have been going for the 16/15/3 direct drive setups ending up with a 17000rpm at 27amps

Like he was telling me I would get longer run times due to less current requirements with a gearbox but if you do all the calculations with the weight of the plane ETC you are talking few minutes on the end of the pack and if I want speed which I did (HEY it is a Jet Right)
Then the direct drive setup is the way to go...

The only downside I have found on the system is the battery packs get pretty ole warm if you run at full throttle the whole flight with the calculations on that were about 27 amps with the 6x5 it is no wonder. I am thinking of trying a 5x5 so I can get about 20000 RPM at 20 amps..

I need to try some other props but I have been so happy with the performance I just saw no need to but hey you never know I might even be able to go faster!!!
