I have the Lentus kit which I have just started to assemble and I am having trouble with the undercarriage pushrod.I have assembled the U/C as per instructions and it operates manually very smoothly and easily. The problem I have is with the servo and pushrod. I have fitted the HM85G servo using the kit mounts but the alignment seems out. I would have to put a bend in the pushrod as it fouls on the servo body when connected. I have fitted the ball joint in the correct hole on the U/C arm (12mm) yet it is way below the body of the servo and not in line with the servo arm.Cannot figure out where I am going wrong. I will have to re-drill the servo mount holes in the side plate to get the servo to align correctly.Has anybody else encountered this?Paul
Hi Paul, I don't see where there would be any problems.Can you post a picture. With so little info no one can do anything.Greeting macsimu
Ok. Here is a image of the problem. The pushrod as connected as per instructions can not align with the U/C connector with out it being bent at an angle so as to be able to connect. If I put a bend it the pushrod there a chance of it flexing?
I hope this helps explain it better.
I would insert the push rod into the servo arm from below, then it should fit.Greeting macsimu
Hi,if this this measure is not enough, You might drill a slightly bigger hole in the servoarm. Maybe 1,7mm diameter. This will offer You the possibility to move the pushrod up and down.

The main problem is that the servo you have used is higher than the one shown in the drawing.I would just make a bend in the pushrod and leave the rest as is.
Max.
Thank you everyone for the replies.Max. The servo is too high as you say but it is the one recommended in the manual. I shall slide a brass tube over the pushrod and solder at one end where I plan to bend the wire. I can then bend the pushrod to the correct angle and finish soldering the other end thereby making the pushrod much stiffer.Probably overkill.Paul.
Most likely overkill. I am judging it to be 1.5 mm diameter, ample for such a short length. It may even flex a bit on the way, but if it gets the gear from one stop to the other it should be ok.Max.
