on the hm1a you need that plate to mount the rudder gyro to so might not work doing that unless you could find a better place to put the gyro... found this link that you might be interested in has hundreds of different servos and there specs and measurements... http://www.servodatabase.com/ using servo tape and cutting the plate like i did i could probably get the Henge servos to work but the elevator servo might cause a problem cause it sits so close to the motor can...

I mounted my new gyro by my rx in the front so not a problem ,I will let you know how it works out later this week.

just ordered 3 of the exi213 servos and a feathering shaft for the hm1b from hobbypartz.com they have free shipping on orders over $25.00
from what i can tell the hm1a and hm1b are the same accept the hm1b uses a tail motor instead of a belt drive and its not brushless....so i hope the feathering shaft will fit cause i really don't want to have to spend $40 for a v370 head just to get the feathering shaft... |

crap, it might not work mine measured out to be 30.50 L and 3 mm diameter ....well i might be able to use a extra washer on each side to make up the difference....i got one ordered with the servos so i guess i know for sure in a couple days....
thanks for the info.... |

guys on here in the v400 thread are using align feathering shafts cause they can't get one for it eather, but i don't know if it will fit the v370....i asked for measurements and waiting for a reply and if it will fit i will order them they come in 2 packs...
well found out the v400 uses a 4mm shaft so the align wont work unless a align trex 250 shaft will fit.... Last edited by magicmarty; 06-27-2011 at 10:18 PM.. Reason: more info |

found out some of the align 450s use a 3mm shaft but it is 40mm long so i am probably going to have to get those and cut them down to the 30.5mm i need as long as it has enough inner threads i think it will work....anyway they are real cheap so if it don't work i wont be out of much money....can get 4 of them for $1.99 plus shipping...
measured the stock shaft and it has 8mm of threads and the screw only goes in 4.7mm so the aligns have 10mm of threads on each end so i think i can cut off just shy of 5mm on each end and they should work...cause it will leave me 5mm of threads on the ends after i cut it off.... |

Hey Marty
Are the 370d05 blades made of Fiberglass or covered foam blades? There cheaper than The Hm1a blades, I also ordered some carbon fiber blades from Helipal that should also fit yours! |

there fiberglass from the looks of the one i busted up the other day in the crash....they are the same length as the hm1a i believe its 260mm .....
one thing im going to have trouble with in the conversion is i plugged a servo in the rudder channel on the rx and it wont drive a servo....if i touch the throttle it slams the servo hard and starts clicking the gears....wonder if im going to have to use a signal converter and go with a brushless tail motor instead of doing the belt drive i really want to do....or i might have to get a different rx.....ffs im going to have to much $$$ in this heli when its done i could have just got a v450 .... |

I was wondering how Walkera sets those rx to work with brushed motors?I was thinking of trying that rx but didn't know how to set that up as well.If you can solve the problem it will benefit me as well so good luck on the solution!

there is no way to get the rudder ch to drive a servo on the rx for the v370 and the v400 ...i plugged in a servo to the rudder ch and it did nothing until i raised the throttle and then it slammed the servo one direction and started popping the gears....a guy on the v400 thread on a different forum is a electronics wizz he makes his own signal converter and such and he can't figure out how to get this rx to drive a servo....a signal converter wont work on the rudder channel because it only drives voltage one direction and has a wider band then a servo requires so it only works for brushless motor conversion....i could go with a brushless main and then come up with a way to mount a small brushless on the tail as a direct drive perhaps....or just get the 4f200 rx and do the belt drive i dunno yet....for now i just want to get the servos mounted and get it back in the air....what little time i had it up the tail is super solid its real surprising how good the tail holds to be a motor driven setup....
so you don't want to use this rx for your conversion as of to date no way a servo will work on the rudder ch.... |

omg dude , i just seen that HobbyKing has the hm1a in a bind-n-fly version for $94.00
i might just get one instead of ordering the parts to do the conversion if i decide to do it.... |

It's flys really good for a flybar heli,has alot of mod potential as you can use normal( non Walkera) parts that bolt on and work.I had trouble with my tail gyro and tried for a week to get it going ,finally replaced it with a Assan Ga250 mems gyro from hobby king for $13 .I had bought my Hm1a from wow , was supposed to have been test flown and setup, but was pretty disappointing to pay extra for nothing!But the good thing is I learned for my self and won't be needing to buy premade any more!

what i was thinking was instead of getting all the parts to convert the 370 to a belt drive i could just get the hm1a as a bnf and have everything i need and then have extra parts for another project .....the parts if i order them separate are going to be over $70 so for $30 more i can just get the whole heli....but they are out of stock on them at the moment but i requested a email notice when they get back in stock....
i ordered a brushless motor and esc for my 370 and also had to get a signal converter...got the elite 370 4100kv it is a in runner ,because of clearance on the front servo i didn't go with a out runner ....the stock motor is 24mm diameter and the one i ordered is 20mm so it will give me a little bit more room if i need to move the front servo up a bit to get the EXI servos to fit.... hopefully they will be in this week along with the align feathering shafts i have to make work cause HeliDirect wont have the 370 shaft in stock until August... |

dang servos still didn't come in today, but i did get the align feathering shafts in and cut one down and got it to work perfectly....i used the extra spacer that goes between the bearings that came with them and placed it on the end so i didn't have to cut as much off cause they didn't have as much threads as i thought....so instead of cutting to 30.5mm i ended up with it at 33.5 which gave me a extra 1.5mm on each end....so now i got to cut the other 3 the same and i will have extra's for the next time i need one....

I converted my Hm1a to exi213 servos , alot of fitting but I was able to get them in there.I've only hovered so far but seems to respond quicker with more precision!Also on the Hm1a thread there's a guy that has already bolted on the v370d05 head , direct bolt on, no mod!He's going to use the Micro beast fbl system,while I'm going to try the rx from the v450.Only problem for me is I'd need the 2801 tx so it may be awhile before I can afford the $!
