-hey everyone, recently i have converted one of my ENV 700 nitros to a 635 nitro. any one who is interested in doing the conversion all you need is to get the 635 boom, torque tube,625mm blades, and boom supports.
1.)ND-YR6-AS2001 - Tail Boom
2.)ND-YR6-AS2002 Torque Tube
3.)ND-YR6-AS2003- Boom Support Set
-the ENV does not use the two boom clamps like the ballistic does to mount the tail servo. The ENV Nitro has the tail servo in the frame to assure that it does not get drenched in oil, also this helps with the CG. since the tail push rod that comes with the conversion is for the ballistic 635, it is about an inch to short to reach the other side of the boom. so what i have done is take a push rod from the 700 size kit and cut it to the length it should be and make 3 small (Zs) at the end of the rod with some pliers to bend it. once the rod has this( Z) pattern take some needle nose and curve them a little. once this is done take a little bit of J.B. weld and put it on the end of the rod and push the link into it, the zig zag pattern is there to assure that it gives the link a little bit of resistance so it does not pop out. Note, make sure to have the side with the J.B. weld towards the frame of the helicopter so it is exposed to less oil, over time the oil might break down where the J.B. weld is.
- another option is to cut the tail control rod to the correct length and put threads on it.
(if anyone knows what tool that could be use to do this please let me know)
- the other thing about converting the ENV into a 635 machine is that weight could become an issue. i have talked it over with a few other people and cutting out all the non-essencials such as....
1.) boom support bridge
2.) head button the the top of the rotor head
4.) (if you have on already) remove header tank
5.) try to get a smaller receiver pack like something with 1300mah to reduce the weight
6.) if you have 3 metal bearing blocks take two out and replace with the plastic ones and keep the metal one on the top.
- i have not tested this conversion yet because of the weather here in NY, it has been in the negatives the last week or so. hopefully next week it will bee warm enough to test it out. If anyone beats me to it please post your thoughts about the conversion and what you find that is different in the flight characteristics and setup.
-thank you Brian Butler for helping me out!
