| If you have to use those old wooden blades, they could be dried out and ready to crack.
I would strip off any covering and any fiberglass reinforcing around blade roots. Examine blades for any cracks/condition, put new fiberglass around blade root with thin CA or thinned out resin so it will soak into wood real good and should make a rock hard root area, re balance and get them a go.
Just be careful with them as those crickets like to be wound up pretty good for decent performance.
Just remembered something else.
Adjust the angle up and down of the tail boom so that the tail rotor drive wire has as streight a shot as possible to tail gearbox. The boom will probably end up drooping down a little for proper alignment of drive wire.
Adjust the drive wire guide also during this process so that drive wire also runs in the slot in the tail boom without rubbing on tail boom material.
We used to have a problem with the tail boom fatigue cracking at the slot area and we would put some fiberglass cloth around that area all the way around the boom and saturate with thin CA or thin resin.
The little dampener music wire on the head likes to break so have some extras on hand at field. |
