how does this thing fly or should I ask, how well does it 3D? Does it feel like a brick? Im going back and forth trying to decide whether to convert my T700 to electric or go with one of these radikals for cheaper operating costs.

well i converted one of my trex 700's to eletric for a while, they are hard on battery's and i was flying 12s plus if you run a powerfull system the maingear and tail gear like to strip out .plus the fact you have 2 batteries so you need 2 chargers and so on and so on needless to say not much flying time, because the batteries are always chargeing and at the price of a pair of 6s packs who can afford to have multiple set's.
personally i like the trex 700 better as a nitro. as for the radical operation costs, you get four hours flight time to a gallon of gas witch with the cost of oil is about $4.00, with a 700 nitro you get 40 minutes tof flight time to a gallon of fuel that costs $30.00 plus, the cost of eletric 700 is close to the nitro 700 depending on how many flights a pack last's. the radical fly's great, does 3D ok, it does wiegh 10 pounds so some manuvers are slower like tic tocs and rainbows ,other wise just like a 50 nitro.however once the new gear ratio gets here and the motor is fully broke in so you can scream it, it will have more pop,i have for short bursts spooled it to 2150 and it pops pretty good, tic tocs are decent, on par with most 50 nitro's. |

I have plenty of chargers to handle charging a few 6S packs at a time and would go with the turnigy packs (two 6S 5000mah 30C for $200). I agree with ya on the constant charging, but it seems that the performance of a 700E would be incredible (suzi hans conversion is what I was planning on), using a 400kv motor and larger pinion would take care of the gear stripping issue. The radikal seems to be a nice option as well like you said- long flight times and dirt cheap fuel and realistically more economical. Decisions decisions

if your looking for aweome performance for cheap do a 12s setup in a trex 600e I have 2 and they are awesome,scorpion 4035 560 kv motor hv 85 2 6s 3000 mah packs 7 pounds 4000 plus watts,5 min flights, 620 wide chords at 2300 2500 headspeed,These make my trex 700e look pathetic and they are easy on batteries and maingears, and half the cost.You still spend most the time chargeing but atleast the batteries will last 200 cycles because they don't get abused, my packs come out luke warm flying as hard as i can.
Btw I'm pretty sure the suzi hans conversion is flybarless only.It does away with the bell cranks and uses direct servo links, so without the extra travel from the bellcranks the stk head won't work correctly. |

I forgot to mention the 600E as an option on 10 or 12S...thats probably the way I will end up going as you said it would be a bit cheaper than a 700E conversion. You are correct on the suzi hans being a flybarless only set up which I already have the FBL head but not the stab unit so theres more money needed for that route.

Radikal G20 info
Hey guys, The Radikal flies wonderfully. I am running the CH ignition on a 2 cell 2500 lipo and after 3 tanks time I only put back in 375 Ma. Running the Align DS610's on the swash and they behave nicely. As far as the build goes, I believe in using flat washers on all the installations where the frame holes are slotted for gear lash adjustment. Also things that might require occasional adjustment I went with regular socket cap screws in place of the button head ones. Mutch better grip with the larger
allen head for removal. I have been running Colman fuel and the Lawn Boy oil for breakin. At 32 to one it burns real clean. No after run smell like regular gasoline. I will switch to the Amsoil Saber oil on the second gallon of Colman fuel. I am flying with throttle curves, no governor needed as I see it. Buy it and enjoy this great heli! Just ask Bobby! :-) |

I agree with mtheliflyer. I used flat washers and standard allens in the slotted holes as well. Except the one behind bell crank, just for clearance. Will post some pics tonight after I finsh the tail control. I also moved canopy mounts for a better fit in my oppinion. As I know you have to trim around muffler or it melts. I have made a few changes as you will see in the pics soon.

Radikal G20
Rodney speaks about canopy clearance on the muffler. I oppted to cut the canopy hook white spacer that screws to the lower front elect. bay down to 3/8 inch This lets the canopy clear the muffler fine in the canopy recess molded into it. No heat damage has occured.

I'm doing the same thing with the frame bolts, regular socket allens with washers.
for canopy clearance i found that if you preload the canopy it norrows up and clears. |

Concerning type head you have
Make sure you have the right main shaft for your head that you are using ... You must have a 4mm hole in the main shaft for the HD...3mm hole for the LT head... Do not try to run a Lt head with a 4 mm hole main shaft. |

hey bobby you should put the whole cnc raven upgrade head on your's, you'll need shades to look at , it'll be so shiny
http://www.heli-world.com/detail.aspx?ID=8753 I've always whanted one of these,heck if i had your discount i would have them on all my century's should be no problem to put the 7mm spindle in it, just swap your grip bearings from your radical into the metal grips and the radical dampers. I use the cnc raven upgrade headblock on all my century's, includeing my 3 raven 's and 2 nx 50's and now my radical. It's only $24.00 bucks . http://www.heli-world.com/detail.aspx?ID=8496 the stk head block is pretty woosy will break with just a miner crash.plus with this block you get a wider flybar range of angle.for faster rolls and flips.and i twill take a crash, ask me how i know couple things though is it uses the hawk seesaw pivot parts, the kinetic 50 ones are the same also.me i had 5 hawks so i had these parts in spades laying around. second thing is the inner diameter for the dampers is slightly smaller so the shims for the radical dampers will not fit, so you need to find a couple orings to take there place,the radical dampers are considerabley narrower then the raven/kinetics dampeners.so have to be shimmed out to the edge of the head block. |
